In October, the team has announced various Swipe Improvement Proposals (SIP), product upgrades and migration, additional coin listings, and partnerships to make your cryptocurrency experience as easy as possible. Swipe Verified Pages Swipe’s Instagram, Facebook, and Telegram accounts are now officially verified. Make sure to follow only the official pages of Swipe to get the latest offers, news, product developments, and updates. Also, please be reminded that Swipe has only two official channels: T.me/SwipeWallet(verified) T.me/Swipe(Announcement Channel) Swipe Discord Channel The team has officially opened a Discord channel to connect with users who have Discord accounts. Swipe gave away a total of $1,000 in Swipe Token (SXP) to 10 random winners who joined the Discord channel and followed Swipe’s official Twitter account. The ten winners were announced last October 6 on Swipe’s Discord channel. Updates on Swipe Cards & Migration The Swipe Slate card is now upgraded to 8% cashback with $30,000 referral rewards activated immediately, same rebates, and on-chain staking rewards with governance. The monthly spending limit for Swipe Slate is also now upgraded to 50,000 Euros. Other Swipe cards such as Saffron, Sky, and Steel will be migrated to the Binance card platform. Users of these cards will be able to use it and SXP lockups via their Binance account, including the migration of benefits and rebates. SXP lock-up card tiers for Binance cards and Swipe cards ordered on Binance.com will be released soon to match up to existing benefits, perks, and rebates. Swipe Slate will remain on the Swipe Wallet platform for SXP Elite users. This move shows Swipe’s commitment to push the Swipe Issuing platform products to businesses, like Binance, which will help the SXP deflationary ecosystem. Swipe Improvement Proposals Last of October, the Swipe team announced on its official channel the voting procedures for the Swipe Improvement Proposals (SIP) on Swipe Governance. On October 5, Swipe announced the voting procedure for the Swipe Improvement Proposal 1 (SIP-1). Those who staked SXP can vote to upgrade the staking contract to add a reward claim period controlled by SXP holders. On October 8, the team announced that the SIP-1 has now passed with 3,456,709 $SXP staked for YES while 0 SXP for No. SIP-3 was then made available on Swipe Governance last October 22. Staked $SXP can vote on upgrading the staking contract to add an unstake period for $SXP collateral. This proposed unstake contract upgrade enables a dynamic period in which new stakers have to wait to be able to remove their collateral from the network via a decentralized trustless system. On October 25, SIP-3 has been passed, with 5,283,856 $SXP staked for YES while 119,080 $SXP for NO. This was followed by the announcement of the voting procedures for the SIP-4. Those who staked $SXP can vote in favor of, as well as against, the increase in the daily staking rewards for on-chain $SXP users securing the Swipe Network. However, SIP-4 had an issue in execution due to inadvertently adding a “space” in the proposal parameter, which throws a smart contract error. This was tested before deploying, and when it was copied, the space was accidentally added in. The team re-proposes SIP-4 via SIP-5, which is now available on Swipe Governance. This proposal corrects the parameter with SIP-4. View the details of the Swipe Governance Proposals here:https://app.swipe.org/dashboard Coin Listings Swipe has added several coin listings on its platform. Adding to its list of supported cryptocurrencies are Venus Protocol ($XVS), Near Protocol ($NEAR), Kusama ($KSM), Ocean Protocol ($OCEAN), Filecoin ($FIL), and $AAVE. Swipe users can now buy and sell these cryptocurrencies with credit/debit cards, instant exchange, and trading, and spend it using Swipe Visa cards.

SXP Wrapped in BSC $SXP wrapped on BSC is coming. The team will enable fee-free wraps and launch cross-chain staking when this deploys. This will save users high fees and latency currently faced on Ethereum. Swipe Slate Staking Rewards Swipe has distributed the first week and second week of Swipe Slate on-chain staking rewards to Slate cardholders last October 13 and 20. Swipe Slate cards can be ordered with a 30,000 $SXP stake lock up, which includes 8% Cashback in BTC, top brand rebates, and on-chain staking rewards.

It is the fifth Syrup pool project to be announced by PancakeSwap. The SXP staking campaign will run for 200,000 BSC blocks from block 1582740 to 1782740 (approximately 6.5 days with a block time of 3 seconds), which means that there will be 0.5 SXP given out to SYRUP holders in each block. BEP20 SXP will also be circulating and transferable on BSC when PancakeSwap starts the SYRUP pool, so users will be able to harvest your SXP tokens and trade on PancakeSwap at any time. Also, earn $CAKE by being a liquidity provider for $SXP-BNB on Binance Smart Chain with double rewards for approximately seven days followed by 1x on-going. To wrap your $SXP from ERC20 to BEP20, just deposit $SXP into your Binance Account and withdraw via the Binance Smart Chain option. The Swipe Wallet app now supports BEP20 BSC deposits for all supported coins. Simply use the same address you normally use to deposit ERC20 based supported cryptocurrencies to deposit Binance Smart Chain BEP20 based ones such as $SXP, ETH, etc. Spend Fiat Using Swipe Visa Cards On October 23, Swipe announced that Swipe Visa card holders can directly use fiat currency as their funding source.

I lost it all (this my old rogerver bcashy troll account btw) I don’t even know how to start but as of yesterday I’m officially broke, I ruined my life and future. I’m a 23yrs guy, my journey with Bitcoin started in 2014. I bought it to actually use it not sure if people do that nowadays? but The HODL journey didn’t start until the beginning of 2017 as I notice the $ value in my blockchain wallet steadily increasing didn’t even know how or why it was increasing I thought it was a glitch making me free money for this reason I decided to go ALL IN I dumped my life saving into Bitcoin. price was around 1-2K $ and I was able to get 11 BTC in total. Unfortunately before the Bullrun start I lost around 4 coin due to ICO"s scams and just buying shitcooins in poloniex with zero trading knowledge(had a great time with the trollbox). After my loss I took my coins out of the exchange and held in a cold wallet, Fast forwards September 2017 the price kept going up I couldn’t even believe it specially after it broke past 10k I was so euphoric matter fact I was chilling in here, in this subreddit celebrating with everyone posting memes etc.. When BTC hit 20k my greedy asss still didnt wanna sell I didn’t have a price target I though it will keep going up forever. It was going so quick I couldn’t even process what was happening I told my siblings I was rich they told me to sell this bubble but I said "HELL NO! I was part of the moonboy gang we don’t sell we HOODL" I was 19 at the time. seeing this type of money was unreal I had more than 6 fucking figures in my wallet. Eventually we topped out at 20k I didn’t sell although the price kept going down and down and Depression started to hit after we dropped below 10k specially when it went down more near the 3k level I started to regret everything kicking my self for not listening to my siblings when they told me sell. Nonetheless I still had faith in Bitcoin and knew one day we will recover but I needed to accepted the fact that it might take months maybe years to get back to ath. for this reason I disconnected from the crypto community I had to forget about Bitcoin so I shifted my focus somewhere else luckily I stumbled across this popular game called “Fortnite” it took all my time and distraction away from my crypto for a good year or two I barely even noticed the peak of 2019. Anyways mid-late 2019 I got heavy in the stock market I started to see all these guru make insane amount of money just day trading. I was more of an investor type guy but I consumed so much information about day trading and how the psychological aspect is so important, I guess I mastered a bit of that by holding Bitcoin throughout the bear market. Anyways recently in August during the Bitcoin rally I though I had enough skills and decided it was finally time for me to trade Bitcoin specially because it was tradable 24/7 I wanted to start increasing my money and stop sitting on my coins I've had enough of the bear market I thought it was gonna be another P&D episode specially after I started to get deeper in the Crypto community and understood how price moves. I used to be Bitcoin maximalist but then I started to notice the suspicious activity around bitcoin, I came to realize that bitcoin was not the same as it was before, these toxic unregulated entities have turned bitcoin into a giant ponzi playground with everyone being brainwashed by these crypto twitter advocates who are nothing but CZ binance acting puppets. I know it sound crazy but it’s true, the receipt it out to the public, the price is manipulated by Tetther Mafia and these scam exchange. I don’t believe in conspiracy but neither do I believe in coincidence, I witnessed this fraud my own eyes, Whale-alert notified me every time Tetther printed new money and sent it to exchanges and next thing you the price went up. Ever since they added derivative I assume they manipulate the price in spot to liquidate future traders. This whole rally was propt by Tetther mafia using the overall condition in the market as an excuse to attempt artificial FOMO and bring real liquidity in this fake liquidity pool. As the fraud was getting more obvious I started to despise Bitcoin and traded the ponzi based off emotions I neglected the technicals I didn’t have risk management and eventually got liquidated. This is my 3yr+ journey went from 11 btc to 0.. I feel horrible,sad, hopeless and disappointed this was my whole networth vanished in 1-2month. I deprived myself from so many things these last few years hoping my investment grows enough to fund my future. My family still think I’m holding Bitcoins I feel so bad I let them down not sure I'll be able to recover from this. Ps: for those saying Tetther is an old conspiracy trust me this time is different and incomparable to the previous years, the fraud is fully transparent now. Their activity has been very suspicious and concerning lately I’m sensing a major exit-scam. this will impact the whole crypto space because this unbacked counterfeit USD holds most if not all the order book liquidity.
Sàn OKEx và tất tần tật những điều liên qua mà bạn cần phải biết
Tìm kiếm sàn giao dịch tiền điện tử phù hợp để tham gia là một trong những nhiệm vụ quan trọng nhất đối với bất kỳ nhà đầu tư tiền điện tử nào. Trong bài viết này chúng tôi trình bày chi tiết và mang đến cho bạn những thông tin quan trọng nhất về OKEx Exchange. Trong này chúng tôi sẽ giải quyết các câu hỏi phổ biến như “Sàn giao dịch OKEx có an toàn không? Chúng tôi sẽ xem xét lý do tại sao một nhà đầu tư tiền điện tử có thể sử dụng sàn OKEx để trao đổi tiền điện tử, nêu lên nhược điểm và chỉ cho bạn cách để bắt đầu trao đổi mua bán trong mục hướng dẫn. Đừng bỏ lỡ bất kỳ chi tiết quan trọng nào về sàn OKEx nhé.
OKEx là gì?
https://preview.redd.it/zi3zxvppwrx51.png?width=800&format=png&auto=webp&s=c83e13d0d227adecffed24c3d4e5d4a20e298179 Sàn OKEx Sàn giao dịch OKEx là sàn giao dịch tiền điện tử hàng đầu cho phép bạn mua và bán các loại tiền điện tử khác nhau. Sàn giao dịch được thành lập vào năm 2014 và được hỗ trợ bởi các quỹ đầu tư mạo hiểm như Giant Network Group, Longling Capital, Ceyuan Ventures, Qianhe Capital Management, eLong Inc và Ventures Lab (đồng sáng lập bởi nhà đầu tư blockchain Tim Draper) với hàng triệu đô la vào các khoản đầu tư. Vào ngày 11 tháng 4 năm 2018, công ty đã công bố mở rộng sang Malta, với nỗ lực cung cấp khuôn khổ quy định hợp lý cho các doanh nghiệp blockchain và trao đổi tài sản kỹ thuật số. Tháng 5 năm 2018, sàn giao dịch này đã trở thành sàn giao dịch tiền điện tử lớn nhất thế giới theo doanh thu được báo cáo. Đến tháng 6 năm 2018, nền tảng này đã trở thành một trong những sàn giao dịch lớn nhất ra mắt và cung cấp dịch vụ nhãn trắng để trao đổi tiền điện tử với điều kiện người đăng ký phải có kinh nghiệm trong ngành vững chắc và 2,5 triệu đô la trong tài khoản của họ. Vào ngày 25 tháng 11 năm 2019, công ty đã công bố bốn đối tác chính cho mã token tiện ích toàn cầu “OKB”. Vào tháng 2 năm 2020, OKEx thông báo rằng blockchain của riêng họ có tên là OKChain sẽ bắt đầu thử nghiệm. Sàn giao dịch tiền điện tử có trụ sở tại Malta lần đầu tiên tiết lộ rằng họ đang phát triển một sàn giao dịch phi tập trung (DEX) được xây dựng trên nền tảng của nó vào tháng 3 năm 2020. Hiện tại, OKEx có khối lượng trao đổi tiền điện tử cao thứ hai trên toàn cầu và không còn xa nữa sẽ cạnh tranh với Binance để giành vị trí dẫn đầu. Điều này có nghĩa là một số thị trường tiền điện tử do OKEx cung cấp là lớn nhất trên thế giới. Khi sàn giao dịch mở rộng cơ sở khách hàng ra ngoài châu Á, hy vọng sàn giao dịch này sẽ tiếp tục phát triển và đè nặng áp lực lên Binance để giành thị phần. Ban đầu, công ty có trụ sở tại Hồng Kông. Tuy nhiên, vào tháng 4 năm 2018, sàn giao dịch OKEx đã xác nhận rằng họ sẽ chuyển đến Malta. Giám đốc điều hành OKEx giải thích rằng Malta không chỉ là một quốc gia thân thiện với blockchain mà còn có các quy định nghiêm ngặt hơn về các tiêu chuẩn chống rửa tiền. Sàn giao dịch cởi mở và nói rằng những tiêu chuẩn này rất quan trọng để bảo vệ khách hàng của họ và đây là động lực quan trọng cho việc di chuyển. Điều này có nghĩa là nếu bạn đang tìm kiếm một sàn giao dịch có quy định chặt chẽ hơn về tiền điện tử, thì OKEx có thể là một trong những sàn giao dịch phù hợp với bạn.
Các loại tiền được phép giao dịch : Hơn 100 loại tiền điện tử khác nhau có sẵn trên sàn giao dịch.
Sàn giao dịch lớn thứ hai: Dựa trên khối lượng giao dịch, OKEx là sàn giao dịch tiền điện tử lớn thứ hai trên toàn cầu trong các sàn tiền ảo.
OKEx được sử dụng ở những quốc gia nào? Sàn giao dịch chấp nhận hầu hết các quốc gia từ Châu Á và Châu Âu. Hiện tại, sàn giao dịch có khách hàng từ hơn 100 quốc gia khác nhau.
Gửi tiền thông thường: Không giống như các sàn giao dịch như Binance, OKEx cho phép gửi tiền thông thường qua chuyển khoản ngân hàng, Apple Pay và WeChat Pay.
Bạn có thể sử dụng thẻ tín dụng trên sàn giao dịch OKEx không? Có, sàn giao dịch hỗ trợ thanh toán bằng thẻ tín dụng.
Tính thanh khoản cao: Vấn đề với các sàn giao dịch nhỏ là số lượng lệnh bán có thể bị thiếu hụt. Điều này có nghĩa là nếu một nhà đầu tư muốn mua một loại tiền điện tử trị giá thậm chí là 500 đô la, giá có thể cao hơn. Tính thanh khoản cao có nghĩa là các nhà đầu tư có thể mua loại tiền điện tử đã chọn của họ trong một lần và với cùng một mức giá. OKEx có tính thanh khoản cao thứ hai trên thế giới và điều này giúp việc mua tiền điện tử ở đó trở nên dễ dàng.
Đòn bẩy giao dịch: Sàn giao dịch OKEx cung cấp đòn bẩy gấp ba lần trong giao dịch tiền điện tử.
Phí giao dịch trên sàn OKEx
Hầu hết mọi người sẽ không giao dịch trị giá nhiều hơn 600 Bitcoin khối lượng giao dịch trong 30 ngày. Điều này có nghĩa là phần lớn các nhà đầu tư tiền điện tử sử dụng sàn giao dịch sẽ vẫn ở mức 1. Phí giao dịch cấp 1 là:
Giao dịch thị trường: 0,15% phí nhà sản xuất và 0,2% phí tham gia.
Giao dịch kỳ hạn: 0,03% phí nhà sản xuất và 0,05% phí tham gia.
Giới hạn thanh toán trong 24 giờ: 100 Bitcoin

Về khối lượng giao dịch, OKEx đứng thứ hai sau Binance.

Hướng dẫn mở tài khoản OKEx
OKEx cung cấp cho các nhà đầu tư tiền điện tử một loạt các loại tiền điện tử để lựa chọn. Nó cũng cung cấp các tính năng bổ sung như giao dịch đòn bẩy, giao dịch ký quỹ… Chúng tôi cũng rất thích việc OKEx nhận ra rằng ứng dụng dành cho thiết bị di động là một ý tưởng hay và không thể đợi ứng dụng iOS và Android ra mắt đúng cách. Không giống như các sàn giao dịch tiền điện tử khác như Binance, OKEx cung cấp khả năng gửi tiền tệ Fiat qua chuyển khoản ngân hàng, Alipay hoặc WeChat Pay. Điều này làm cho việc tham gia vào thị trường tiền điện tử trở nên dễ dàng hơn.
Đăng ký sàn OKEx
Điều đầu tiên bạn cần làm khi truy cập trang web OKEx là kiểm tra xem bạn có đang ở trên trang web chính thức hay không. Nhiều kẻ lừa đảo tạo ra các trang web tiền điện tử giả để mô phỏng các sàn giao dịch thực. Để thực hiện kiểm tra, hãy nhìn vào thanh URL trong trình duyệt web của bạn và đảm bảo rằng bạn thấy biểu tượng ổ khóa và dòng chữ “Secure”. Sau đó, bạn hãy sẵn sàng để nhấp vào nút đăng ký.
Điền vào mẫu đăng ký
Bạn có thể đăng ký bằng số điện thoại hoặc email. Bạn quyết định phương pháp nào phù hợp với mình. Tuy nhiên chúng tôi khuyên bạn nên đăng ký trao đổi qua e-mail. Nhập địa chỉ e-mail của bạn và nhấp vào “Request code”. Thao tác này sẽ gửi một mã gồm sáu chữ số đến địa chỉ email của bạn, mã này bạn nhập vào trường “Enter Code”. Sau đó, bạn có thể nhập các thông tin cần thiết, kiểm tra xem bạn đã đọc các điều khoản và điều kiện chưa, và nhấp vào nút ‘Register’.Bạn cũng sẽ nhận được một email tự động xác nhận rằng đăng ký của bạn đã thành công. https://preview.redd.it/7ns1qwrrwrx51.png?width=800&format=png&auto=webp&s=8ad6973d8ef20ccce1b040783e5cbf80f6c95e9f Đăng ký sàn OKEx
Việc bảo mật cho tài khoản khi giao dịch tiền ảo là rất quan trọng. Vì vậy các nhà đầu tư cần phải chú ý hoàn thành việc bảo mật tài khoản trước khi thực hiện bất cứ giao dịch nào. Ở biểu tượng tài khoản cá nhân, nhấp chọn Security Settings để tiến hành các bước bảo mật cho tài khoản.
Funds Password: Thiết lập mật khẩu cho ví của bạn, mật khẩu sau khi được thiết lập sẽ luôn được yêu cầu mỗi khi bạn thực hiện hành động rút tiền.
Mobile Verification: Xác thực số điện thoại. Sau khi số điện thoại của bạn được xác thực thì đây cũng chính là nơi sẽ gửi mã xác nhận về mỗi khi bạn tiến hành rút tiền, thay đổi mật khẩu tài khoản hoặc bất kỳ hoạt động nào liên quan đến bảo mật tài khoản.
Google Authenticator: Bật Google Authenticator để tăng cường tính bảo mật cho tài khoản. Việc bật xác thực thông qua app Google Authenticator rất đơn giản. Chỉ việc tải app về điện thoại và quét mã được cung cấp. Sau đó nhập mã xác thực được hiện thị.
Anti-Phishing Code: Mã chống lừa đảo. Sau khi bật chức năng này thì bất kỳ email xác thực nào được gửi từ OKEx đều sẽ kèm theo mã này.
Nhấp vào P2p Trade bên cạnh Quick Trade để chuyển đến phần giao dịch P2P. Tiếp theo, nhấp vào menu thả xuống tiền tệ và chọn đơn vị tiền tệ bạn muốn. Bạn có thể nhấp vào Sell để xem lại các đề nghị bán có sẵn hoặc chọn Order Book xem lại tất cả các lệnh mua và bán hiện có. Hiện tại thì sàn OKEx chỉ mới hỗ trợ người dùng Việt Nam nên các giao dịch của người Việt trên sàn này vẫn còn khá ít (hầu như là không có). Cuối cùng, chỉ cần xác nhận chi tiết giao dịch của bạn. https://preview.redd.it/693hmoivwrx51.png?width=800&format=png&auto=webp&s=bd1661297af24014068538e0f8fcfe7ef00b2754 Giao dịch P2P trên sàn OKex

Việc lựa chọn sàn giao dịch tiền điện tử là một quyết định rất cá nhân. Sự trao đổi tốt nhất cho một người có thể là sự lựa chọn sai lầm cho người khác. Sàn OKEx chắc chắn có sự hỗ trợ mạnh mẽ từ các nhà đầu tư mạo hiểm và một trong các sàn tiền ảo lớn nhất trên thị trường. Nó cũng cung cấp cho khách hàng nhiều tính năng hơn các sàn giao dịch khác, làm cho sàn giao dịch trở nên hấp dẫn hơn đối với các nhà giao dịch tiền điện tử có kinh nghiệm.

Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses. Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes. First, some background. Here is a summary of how custodians make us more secure: Previously, we might give Alice our crypto assets to hold. There were risks:
Alice might take the assets and disappear.
Alice might spend the assets and pretend that she still has them (fractional model).
Alice might store the assets insecurely and they'll get stolen.
Alice might give the assets to someone else by mistake or by force.
Alice might lose access to the assets.
But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
Alice can't take the assets and disappear (unless she asks Bob or never gives them to Bob).
Alice can't spend the assets and pretend that she still has them. (Unless she didn't give them to Bob or asks him for them.)
Alice can't store the assets insecurely so they get stolen. (After all - she doesn't have any control over the withdrawal process from any of Bob's systems, right?)
Alice can't give the assets to someone else by mistake or by force. (Bob will stop her, right Bob?)
Alice can't lose access to the funds. (She'll always be present, sane, and remember all secrets, right?)
See - all problems are solved! All we have to worry about now is:
Bob might take the assets and disappear.
Bob might spend the assets and pretend that he still has them (fractional model).
Bob might store the assets insecurely and they'll get stolen.
Bob might give the assets to someone else by mistake or by force.
Bob might lose access to the assets.
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are! "On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid". "Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since." "As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!" "Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?" "Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party." "Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!" "What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven." "Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!" "We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies. And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often". How many holes have to exist for your funds to get stolen? Just one. Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so? If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security. The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle. And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet? Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds. So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
ANY CERTAINTY BALANCES WEREN'T EXCLUDED. Quadriga's largest account was $70m. 80% of funds are in 20% of accounts (Pareto principle). All it takes is excluding a few really large accounts - and nobody's the wiser. A fractional platform can easily pass any audit this way.
ANY VISIBILITY WHATSOEVER INTO THE CUSTODIANS. BitBuy put out their report before moving all the funds to their custodian and ShakePay apparently can't even tell us who the custodian is. That's pretty important considering that basically all of the funds are now stored there.
ANY IDEA ABOUT THE OTHER EXCHANGES. In order for this to be effective, it has to be the norm. It needs to be "unusual" not to know. If obscurity is the norm, then it's super easy for people like Gerald Cotten and Dave Smilie to blend right in.
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
First report within 1 month of launching, another within 3 months, and further reports at minimum every 6 months thereafter.
No auditor can be repeated within a 12 month period.
All reports must be public, identifying the auditor and the full methodology used.
All auditors must be independent of the firm being audited with no conflict of interest.
Reports must include the percentage of each asset backed, and how it's backed.
The auditor publishes a hash list, which lists a hash of each customer's information and balances that were included. Hash is one-way encryption so privacy is fully preserved. Every customer can use this to have 100% confidence they were included.
If we want more extensive requirements on audits, these should scale upward based on the total assets at risk on the platform, and whether the platform has loaned their assets out.
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever. Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see. It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation. A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7. History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance. Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.) Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive. Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today. Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well. Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do. Facts/background/sources (skip if you like):
The inspiration for the paragraph about splitting wallets was an actual quote from a Canadian company providing custodial services in response to the OSC consultation paper: "We believe that it will be in the in best interests of investors to prohibit pooled crypto assets or ‘floats’. Most Platforms pool assets, citing reasons of practicality and expense. The recent hack of the world’s largest Platform – Binance – demonstrates the vulnerability of participants’ assets when such concessions are made. In this instance, the Platform’s entire hot wallet of Bitcoins, worth over $40 million, was stolen, facilitated in part by the pooling of client crypto assets." "the maintenance of participants (and Platform) crypto assets across multiple wallets distributes the related risk and responsibility of security - reducing the amount of insurance coverage required and making insurance coverage more readily obtainable". For the record, their reply also said nothing whatsoever about multi-sig or offline storage.
In addition to the fact that the $40m hack represented only one "hot wallet" of Binance, and they actually had the vast majority of assets in other wallets (including mostly cold wallets), multiple real cases have clearly demonstrated that risk is still present with multiple wallets. Bitfinex, VinDAX, Bithumb, Altsbit, BitPoint, Cryptopia, and just recently KuCoin all had multiple wallets breached all at the same time, and may represent a significantly larger impact on customers than the Binance breach which was fully covered by Binance. To represent that simply having multiple separate wallets under the same security scheme is a comprehensive way to reduce risk is just not true.
Private insurance has historically never covered a single loss in the cryptocurrency space (at least, not one that I was able to find), and there are notable cases where massive losses were not covered by insurance. Bitpay in 2015 and Yapizon in 2017 both had insurance policies that didn't pay out during the breach, even after a lengthly court process. The same insurance that ShakePay is presently using (and announced to much fanfare) was describe by their CEO himself as covering “physical theft of the media where the private keys are held,” which is something that has never historically happened. As was said with regard to the same policy in 2018 - “I don’t find it surprising that Lloyd’s is in this space,” said Johnson, adding that to his mind the challenge for everybody is figuring out how to structure these policies so that they are actually protective. “You can create an insurance policy that protects no one – you know there are so many caveats to the policy that it’s not super protective.”
The most profitable policy for a private insurance company is one with the most expensive premiums that they never have to pay a claim on. They have no inherent incentive to take care of people who lost funds. It's "cheaper" to take the reputational hit and fight the claim in court. The more money at stake, the more the insurance provider is incentivized to avoid payout. They're not going to insure the assets unless they have reasonable certainty to make a profit by doing so, and they're not going to pay out a massive sum unless it's legally forced. Private insurance is always structured to be maximally profitable to the insurance provider.
The circumvention of multi-sig was a key factor in the massive Bitfinex hack of over $60m of bitcoin, which today still sits being slowly used and is worth over $3b. While Bitfinex used a qualified custodian Bitgo, which was and still is active and one of the industry leaders of custodians, and they set up 2 of 3 multi-sig wallets, the entire system was routed through Bitfinex, such that Bitfinex customers could initiate the withdrawals in a "hot" fashion. This feature was also a hit with the hacker. The multi-sig was fully circumvented.
Bitpay in 2015 was another example of a breach that stole 5,000 bitcoins. This happened not through the exploit of any system in Bitpay, but because the CEO of a company they worked with got their computer hacked and the hackers were able to request multiple bitcoin purchases, which Bitpay honoured because they came from the customer's computer legitimately. Impersonation is a very common tactic used by fraudsters, and methods get more extreme all the time.
A notable case in Canada was the Canadian Bitcoins exploit. Funds were stored on a server in a Rogers Data Center, and the attendee was successfully convinced to reboot the server "in safe mode" with a simple phone call, thus bypassing the extensive security and enabling the theft.
The very nature of custodians circumvents multi-sig. This is because custodians are not just having to secure the assets against some sort of physical breach but against any form of social engineering, modification of orders, fraudulent withdrawal attempts, etc... If the security practices of signatories in a multi-sig arrangement are such that the breach risk of one signatory is 1 in 100, the requirement of 3 independent signatures makes the risk of theft 1 in 1,000,000. Since hackers tend to exploit the weakest link, a comparable custodian has to make the entry and exit points of their platform 10,000 times more secure than one of those signatories to provide equivalent protection. And if the signatories beef up their security by only 10x, the risk is now 1 in 1,000,000,000. The custodian has to be 1,000,000 times more secure. The larger and more complex a system is, the more potential vulnerabilities exist in it, and the fewer people can understand how the system works when performing upgrades. Even if a system is completely secure today, one has to also consider how that system might evolve over time or work with different members.
By contrast, offline multi-signature solutions have an extremely solid record, and in the entire history of cryptocurrency exchange incidents which I've studied (listed here), there has only been one incident (796 exchange in 2015) involving an offline multi-signature wallet. It happened because the customer's bitcoin address was modified by hackers, and the amount that was stolen ($230k) was immediately covered by the exchange operators. Basically, the platform operators were tricked into sending a legitimate withdrawal request to the wrong address because hackers exploited their platform to change that address. Such an issue would not be prevented in any way by the use of a custodian, as that custodian has no oversight whatsoever to the exchange platform. It's practical for all exchange operators to test large withdrawal transactions as a general policy, regardless of what model is used, and general best practice is to diagnose and fix such an exploit as soon as it occurs.
False promises on the backing of funds played a huge role in the downfall of Quadriga, and it's been exposed over and over again (MyCoin, PlusToken, Bitsane, Bitmarket, EZBTC, IDAX). Even today, customers have extremely limited certainty on whether their funds in exchanges are actually being backed or how they're being backed. While this issue is not unique to cryptocurrency exchanges, the complexity of the technology and the lack of any regulation or standards makes problems more widespread, and there is no "central bank" to come to the rescue as in the 2008 financial crisis or during the great depression when "9,000 banks failed".
In addition to fraudulent operations, the industry is full of cases where operators have suffered breaches and not reported them. Most recently, Einstein was the largest case in Canada, where ongoing breaches and fraud were perpetrated against the platform for multiple years and nobody found out until the platform collapsed completely. While fraud and breaches suck to deal with, they suck even more when not dealt with. Lack of visibility played a role in the largest downfalls of Mt. Gox, Cryptsy, and Bitgrail. In some cases, platforms are alleged to have suffered a hack and keep operating without admitting it at all, such as CoinBene.
It surprises some to learn that a cryptographic solution has already existed since 2013, and gained widespread support in 2014 after Mt. Gox. Proof of Reserves is a full cryptographic proof that allows any customer using an exchange to have complete certainty that their crypto-assets are fully backed by the platform in real-time. This is accomplished by proving that assets exist on the blockchain, are spendable, and fully cover customer deposits. It does not prove safety of assets or backing of fiat assets.
If we didn't care about privacy at all, a platform could publish their wallet addresses, sign a partial transaction, and put the full list of customer information and balances out publicly. Customers can each check that they are on the list, that the balances are accurate, that the total adds up, and that it's backed and spendable on the blockchain. Platforms who exclude any customer take a risk because that customer can easily check and see they were excluded. So together with all customers checking, this forms a full proof of backing of all crypto assets.
However, obviously customers care about their private information being published. Therefore, a hash of the information can be provided instead. Hash is one-way encryption. The hash allows the customer to validate inclusion (by hashing their own known information), while anyone looking at the list of hashes cannot determine the private information of any other user. All other parts of the scheme remain fully intact. A model like this is in use on the exchange CoinFloor in the UK.
A Merkle tree can provide even greater privacy. Instead of a list of balances, the balances are arranged into a binary tree. A customer starts from their node, and works their way to the top of the tree. For example, they know they have 5 BTC, they plus 1 other customer hold 7 BTC, they plus 2-3 other customers hold 17 BTC, etc... until they reach the root where all the BTC are represented. Thus, there is no way to find the balances of other individual customers aside from one unidentified customer in this case.
Proposals such as this had the backing of leaders in the community including Nic Carter, Greg Maxwell, and Zak Wilcox. Substantial and significant effort started back in 2013, with massive popularity in 2014. But what became of that effort? Very little. Exchange operators continue to refuse to give visibility. Despite the fact this information can often be obtained through trivial blockchain analysis, no Canadian platform has ever provided any wallet addresses publicly. As described by the CEO of Newton "For us to implement some kind of realtime Proof of Reserves solution, which I'm not opposed to, it would have to ... Preserve our users' privacy, as well as our own. Some kind of zero-knowledge proof". Kraken describes here in more detail why they haven't implemented such a scheme. According to professor Eli Ben-Sasson, when he spoke with exchanges, none were interested in implementing Proof of Reserves.
And yet, Kraken's places their reasoning on a page called "Proof of Reserves". More recently, both BitBuy and ShakePay have released reports titled "Proof of Reserves and Security Audit". Both reports contain disclaimers against being audits. Both reports trust the customer list provided by the platform, leaving the open possibility that multiple large accounts could have been excluded from the process. Proof of Reserves is a blockchain validation where customers see the wallets on the blockchain. The report from Kraken is 5 years old, but they leave it described as though it was just done a few weeks ago. And look at what they expect customers to do for validation. When firms represent something being "Proof of Reserve" when it's not, this is like a farmer growing fruit with pesticides and selling it in a farmers market as organic produce - except that these are people's hard-earned life savings at risk here. Platforms are misrepresenting the level of visibility in place and deceiving the public by their misuse of this term. They haven't proven anything.
Fraud isn't a problem that is unique to cryptocurrency. Fraud happens all the time. Enron, WorldCom, Nortel, Bear Stearns, Wells Fargo, Moser Baer, Wirecard, Bre-X, and Nicola are just some of the cases where frauds became large enough to become a big deal (and there are so many countless others). These all happened on 100% reversible assets despite regulations being in place. In many of these cases, the problems happened due to the over-complexity of the financial instruments. For example, Enron had "complex financial statements [which] were confusing to shareholders and analysts", creating "off-balance-sheet vehicles, complex financing structures, and deals so bewildering that few people could understand them". In cryptocurrency, we are often combining complex financial products with complex technologies and verification processes. We are naïve if we think problems like this won't happen. It is awkward and uncomfortable for many people to admit that they don't know how something works. If we want "money of the people" to work, the solutions have to be simple enough that "the people" can understand them, not so confusing that financial professionals and technology experts struggle to use or understand them.
For those who question the extent to which an organization can fool their way into a security consultancy role, HB Gary should be a great example to look at. Prior to trying to out anonymous, HB Gary was being actively hired by multiple US government agencies and others in the private sector (with glowing testimonials). The published articles and hosted professional security conferences. One should also look at this list of data breaches from the past 2 years. Many of them are large corporations, government entities, and technology companies. These are the ones we know about. Undoubtedly, there are many more that we do not know about. If HB Gary hadn't been "outted" by anonymous, would we have known they were insecure? If the same breach had happened outside of the public spotlight, would it even have been reported? Or would HB Gary have just deleted the Twitter posts, brought their site back up, done a couple patches, and kept on operating as though nothing had happened?
In the case of Quadriga, the facts are clear. Despite past experience with platforms such as MapleChange in Canada and others around the world, no guidance or even the most basic of a framework was put in place by regulators. By not clarifying any sort of legal framework, regulators enabled a situation where a platform could be run by former criminal Mike Dhanini/Omar Patryn, and where funds could be held fully unchecked by one person. At the same time, the lack of regulation deterred legitimate entities from running competing platforms and Quadriga was granted a money services business license for multiple years of operation, which gave the firm the appearance of legitimacy. Regulators did little to protect Canadians despite Quadriga failing to file taxes from 2016 onward. The entire administrative team had resigned and this was public knowledge. Many people had suspicions of what was going on, including Ryan Mueller, who forwarded complaints to the authorities. These were ignored, giving Gerald Cotten the opportunity to escape without justice.
There are multiple issues with the SOC II model including the prohibitive cost (you have to find a third party accounting firm and the prices are not even listed publicly on any sites), the requirement of operating for a year (impossible for new platforms), and lack of any public visibility (SOC II are private reports that aren't shared outside the people in suits).
Securities frameworks are expensive. Sarbanes-Oxley is estimated to cost $5.1 million USD/yr for the average Fortune 500 company in the United States. Since "Fortune 500" represents the top 500 companies, that means well over $2.55 billion USD (~$3.4 billion CAD) is going to people in suits. Isn't the problem of trust and verification the exact problem that the blockchain is supposed to solve?
To use Quadriga as justification for why custodians or SOC II or other advanced schemes are needed for platforms is rather silly, when any framework or visibility at all, or even the most basic of storage policies, would have prevented the whole thing. It's just an embarrassment.
We are now seeing regulators take strong action. CoinSquare in Canada with multi-million dollar fines. BitMex from the US, criminal charges and arrests. OkEx, with full disregard of withdrawals and no communication. Who's next?
We have a unique window today where we can solve these problems, and not permanently destroy innovation with unreasonable expectations, but we need to act quickly. This is a unique historic time that will never come again.
Hướng dẫn cách mua tiền ảo Ripple bằng các hình thức khác nhau
Có vẻ như mọi người đang đổ xô nhảy vào đầu tư tiền điện tử trong những năm gần lại đây. Trong đó Ripple (XRP) đang nhanh chóng trở thành một trong những đồng tiền thay thế hot nhất trên thị trường. Cách mua tiền ảo Ripple nhưu thế nào? Và mua ở đâu? Bài viết hôm nay chúng ta sẽ cùng nhau bàn về vấn đề này.
Ví tiền ảo là nơi lưu trữ, gửi hoặc nhận tiền điện tử kỹ thuật số thông qua việc có một khóa đặc biệt. Ví tiền điện tử có thể là ví vật lý hoặc ví trực tuyến và thường cung cấp dịch vụ trao đổi ngoài việc lưu trữ. Một số ví Ripple bao gồm Leger Nano S – một lựa chọn hấp dẫn đối với nhiều người do hình thức vật lý của nó (nó trông giống như một thẻ USB). Một lựa chọn phổ biến khác là Toast Wallet, một ví trực tuyến miễn phí hỗ trợ XRP. Nó là một ví mã nguồn mở có thể chứa Windows, Android và iOS. Abra Wallet là một lựa chọn khác cho ví trực tuyến cung cấp cả dịch vụ ví và trao đổi. Tuy nhiên, độ tin cậy của nó có phần không chắc chắn, vì vậy hãy cẩn thận khi chọn ví tiền ảo.
Sàn giao dịch Ripple
Sàn giao dịch tiền điện tử về cơ bản là nơi mọi người có thể chuyển và trao đổi các loại tiền tệ khác nhau (có thể là tiền điện tử hoặc đô la). Điều này thường có thể được thực hiện bằng cách chuyển một loại tiền tệ như USD hoặc Euro thành tiền điện tử như Bitcoin hoặc Ripple và ngược lại. Có một số sàn giao dịch khác nhau mà Ripple sử dụng và được đề xuất. Một số trong số những cái được đề xuất nhiều nhất là Binance và Bitsane, nhưng trang web Ripple cũng khuyến nghị Bitstamp, Kraken và thêm một số sàn giao dịch khác. Một số sàn giao dịch này không thể chuyển USD thành XRP (Ripple token), nhưng một số thì có. Trước khi chọn sử dụng, hãy đảm bảo rằng bạn biết tùy chọn nào phù hợp nhất với mình và liệu bạn muốn chuyển trực tiếp từ USD hay sử dụng phương pháp khác như chuyển từ một loại tiền điện tử khác (như Bitcoin hoặc Ethereum) sang XRP.
Có một số sàn giao dịch khác nhau để mua Ripple. Ví dụ sử dụng sàn tiền ảo tốt nhất – Binance. Như thường lệ với nhiều sàn giao dịch, bạn không thể mua Ripple trực tiếp trên Binance bằng USD, vì vậy trước tiên bạn sẽ phải mua một đồng tiền khác như Bitcoin hoặc Ethereum và chuyển chúng sang Binance.. Để mua Ripple bằng Coinbase và Binance, bạn cần phải:
Tạo tài khoản trên trang Binance. Điều này sẽ bao gồm việc tạo mật khẩu và nhập email của bạn vào – những thông tin cơ bản nhất.
Chuyển Bitcoin (hoặc tiền điện tử khác như Ethereum hoặc litcoin) vào tài khoản Binance của mình. Bạn có thể thực hiện việc này bằng cách cuộn qua nút “funds” trên đầu màn hình và nhấp vào “deposit withdrawals”.
Nhấp vào đồng tiền bạn muốn trao đổi ví dụ như Bitcoin (BTC) và chọn nút “deposit”. Sau đó sao chép địa chỉ BTC được cung cấp.
Sau đó, đăng nhập vào sàn giao dịch bạn sử dụng để mua Bitcoin – Coinbase và chuyển đến “accounts”. Bạn có thể mua Bitcoin trên Coinbase bằng tài khoản ngân hàng được liên kết hoặc thẻ ghi nợ.
Chuyển đến ví BTC của bạn ở phía bên trái của trang và nhấp vào “send” BTC. Thường có một khoản phí nhỏ.
Dán địa chỉ Bitcoin mà bạn đã sử dụng trên Binance vào ô “recipient” và nhập số tiền bạn muốn chuyển.
Đăng nhập lại vào Binance và trong phần “funds”, chuyển đến “deposit withdrawals” và kiểm tra “total balance” – bạn sẽ thấy Bitcoin mà bạn đã chuyển.
Để trao đổi Bitcoin của bạn thành Ripple (XRP), hãy nhấp vào nút “exchange” trên đầu trang và nhấp vào “Basic”.
Tìm kiếm “XRP” trong hộp tìm kiếm và chọn từ BTC (vì vậy nó sẽ là “XRP / BTC”). Nhấp vào số lượng Bitcoin mà bạn muốn chuyển sang Ripple (bạn có các tùy chọn bao gồm 25%, 50%, 75% hoặc 100% BTC của mình).
Chọn số tiền bạn muốn và nhấp vào “Buy XRP.” Việc chuyển tiền sẽ được thực hiện nhanh chóng, vì vậy khi bạn đã mua Ripple, hãy kiểm tra lại tiền của mình và bạn sẽ thấy XRP trong tổng số dư của mình.
Cách mua tiền ảo Ripple bằng USD
Theo trang web Ripple, bạn có thể mua Ripple trực tiếp bằng tiền mặt của mình (cho dù đó là USD, EUR hay loại khác) thông qua tài khoản ngân hàng hoặc thẻ tín dụng của bạn. Để bắt đầu bán sẽ thực hiện các bước như sau:
Tạo tài khoản trên Bitstamp và nhập thông tin cần thiết – tên người dùng và mật khẩu sẽ được gửi đến email của bạn.
Đăng nhập vào tài khoản của bạn bằng tên người dùng và mật khẩu được cung cấp, sau đó thay đổi ngay mật khẩu của bạn khi được nhắc. Bạn cũng có thể bật chế độ xác thực hai yếu tố.
Xác minh tài khoản của bạn bằng cách điền vào thông tin được nhắc ở cửa sổ. Bạn có thể tải lên các tài liệu phù hợp với yêu cầu. Nhấn “submit verification request”.
Sau khi được xác minh, hãy chuyển đến tài khoản của bạn và nhấp vào nút “deposit”, tại đây bạn sẽ có thể chọn phương thức chuyển khoản ngân hàng bạn muốn sử dụng ở phía bên trái.
Chọn “international wire transfer” và điền bất kỳ thông tin nào cần thiết.
Sử dụng chi tiết ngân hàng của Bitstamp để chuyển tiền từ tài khoản ngân hàng bạn có sang Bitstamp. Khi tiền của bạn đã chuyển thành công sang Bitstamp, hãy nhấp vào thị trường bạn muốn trao đổi (để mua Ripple bằng tiền mặt, hãy nhấp vào thị trường XRP / USD).
Chuyển đến phần “buy/sell” và nhấp vào “Buy XRP” trong “instant order (simple” Nhập số tiền bạn muốn mua vào hộp “I want to spend” và nhấp vào “Buy XRP”.
XRP sẽ được thêm vào tổng số dư trong tài khoản Bitstamp của bạn. Mặc dù các thủ tục sẽ khác một chút tùy thuộc vào sàn giao dịch bạn sử dụng, nhưng hầu hết đều khá dễ hiểu để sử dụng. Hãy chắc chắn việc nghiên cứu trước khi sử dụng bất kỳ sàn giao dịch nào để tránh bất kỳ trang web bất chính nào. Nhiều người cũng đã sử dụng PayPal như một cách để mua Bitcoin.
Ripple là một giải pháp thay thế cho Bitcoin, Ethereum và Litecoin. Khác với hầu hết các loại tiền điện tử thì Ripple thực sự sử dụng kết nối với các ngân hàng và công ty. Việc trao đổi token của Ripple đã nhanh chóng trở nên phổ biến do nó được cho là có thời gian chuyển giao rất ngắn trong các sàn giao dịch và phí thấp. Vì vậy nếu muốn mua tiền ảo Ripple bạn có thể tham khảo cách cách mua tiền ảo Ripple trên đây.Xem thêm: Cách mua tiền ảo Bitcoin từ A đến Z cho người mới tham gia

Trang web này có cung cấp cho người dùng giao dịch ký quỹ không?
Không, nền tảng này không cung cấp dịch vụ như vậy, nhưng việc quản lý dịch vụ đang làm việc tại đó.

Nếu bạn muốn nhận tiền của mình bằng đô la, vui lòng truy cập trang ví và tạo một địa chỉ mới bằng ví bạn định nhận tiền. Bạn có thể tìm thấy danh sách phí rút tiền Bittrex hiện tại trên trang web.
Phí giao dịch trên sàn Bittrex
Bittrex tính phí hoa hồng 0,2% cho tất cả các giao dịch. Ví dụ: nếu khách hàng mua một bitcoin với giá 10.000 USD, điều này có nghĩa là họ sẽ trả khoảng 20 USD tiền hoa hồng. So với các sàn giao dịch tiền điện tử khác như Binance, Kraken và Bitfinex, phí giao dịch cơ sở của Bittrex chiếm vị trí trung bình – đây không phải là sàn giao dịch rẻ nhất hay đắt nhất dành cho các nhà giao dịch khối lượng thấp. Khi nói đến phí gửi và rút tiền, Bittrex cho phép bạn nạp tiền vào tài khoản đã xác minh của mình bằng thẻ ngân hàng (VISA), chuyển khoản ngân hàng, chuyển khoản SEPA hoặc tiền điện tử. Tiền gửi bằng VISA đi kèm với phí 3%, trong khi chi phí chuyển khoản phụ thuộc vào ngân hàng của bạn. Theo nguyên tắc chung, chuyển khoản SEPA có xu hướng rẻ hơn và nhanh hơn so với chuyển khoản ngân hàng truyền thống. Đối với phí gửi tiền điện tử, Bittrex không tính phí bất kỳ khoản phí nào, bao gồm cả tiền gửi fiat. Tuy nhiên, nó có tính phí rút tiền, với giá của chúng thay đổi tùy theo loại tiền điện tử được rút. Bittrex nhìn chung khá cạnh tranh khi nói đến phí rút tiền. Điều đó nói rằng, chúng không phải là lựa chọn rẻ nhất hiện có khi nói đến giao dịch hoặc rút tiền với khối lượng thấp cho bất kỳ loại tiền điện tử cụ thể nào. Mặc dù vậy, các nhà giao dịch khối lượng lớn vẫn đủ điều kiện để được giảm giá đáng kể khi khối lượng giao dịch trong 30 ngày của họ tăng lên.

For us who use Decentralized Finance (DeFi) as a common term, we know it represents an enormous shift in how we transact with one another: borrowing money, exchanging currencies, how we view insurance, etc. While total assets involved in DeFi still seem to be increasing right now, there are various factors that will prevent us from growing further. DeFi’s largest barriers for adoption Interoperability — Right now Ethereum gas fees seem like they are always increasing and ETH 2.0 may still be 6 months or more away. We need the ability to make DeFi more accessible to individuals who can’t afford high gas prices per transaction and start including native blockchain assets that are stranded on other platforms. Trust — Unfortunately our biggest issue is still trust. While none of us in crypto expect to know the identity of the other party, many of us just send funds to people we don’t know for vague promises of more wealth. In fact, the biggest type of fraud is still the “giveaway scam” which asks offer to send something back — but its only an offer, there is no guarantee. This is totally unsustainable. What about doing business outside of crypto? Ultimately, DeFi doesn’t keep going unless we create methods for non-crypto native businesses to integrate. While the community might approve sending crypto to each other without a safety in place, this will never work for 99% of online marketplaces. So we need:
DeFi options on lower cost platforms
Trading across blockchains
More flexibility for peer to peer transactions
Easier methods for online marketplaces to integrate and use crypto
Bondly is a trusted, transparent and portable swap protocol designed to make you into a marketplace. Our family of trust-enabling, DeFi products are designed to be a part of your everyday buying and selling activities, giving you piece of mind for your next swap or online purchase.
Similar to Binance OTC Trading Portal but directly on-chain and can be sent via any chat app using different blockchains Wallet to Wallet trustless Over the Counter (OTC) trades that are performed by signing a smart contract. Completely portable smart link can be sent via a chat app or on your favorite social media. It will first support all ERC-20 tokens and NFT (Ethereum) then eventually With BSWAP you can:
Sell a large order of a low liquidity token with no risk of slippage
Become your own NFT marketplace by minting the token, setting your own price, then post to your social media for your audience to buy
Buy assets using Debit/Credit card (using our third party partner onramp)
Send smart link in Telegram to someone you know or your favorite group
Similar to Mooniswap but includes rewards token provided to Liquidity Providers on top of fee share Interoperable Decentralized Exchange (DEX) thats easy to use and blockchain agnostic. Requires liquidity provider (LP) participants to pool assets for a portion of transaction fees along with rewards APY rewards. Our pricing engine will compare major cross chain swap options and will let you know the best one to use (even if its not us). Validation is done directly within your Web3 browser (with Metamask) or polkadot.js based Native Wallet. With BOND DEX you can:
Trade native assets on Polkadot with USDC on Ethereum
Get recommendations on the cheapest bridge transaction path
Create your own asset pairs that otherwise might not exist
BOND PROTECT (BPROTECT)
Similar to Paypal/AliPay Express Buyer Protection combined with Escrow.com with a simple UX like Zapper.fi or Zircon This is our most revolutionary product that we feel will have the largest impact to the eCommerce market. PROTECT is decentralized escrow and buyer protection for customers of crypto friendly marketplaces.
Designed to replace all site specific crypto escrow products with an easy to use API and completely smart contract driven product. Marketplaces may still be in a ‘validator’ role for the marketplace transaction but now they don’t have direct access to funds. This mitigates misappropriation by the marketplace along with exit scamming
By participating in the Bondly network, marketplace vendors can represent themselves as BPROTECT ready and show their on-chain transaction history and successful Bondly enabled deals
BPROTECT will have a similar UX to Zapper.Fi that will pull this vendors on chain activity and history into one place across ethereum and our native substrate chain so you can see their status and history
Functions as a ‘Buyer Protection’ similar to most major marketplaces, where customers are protected by collateral within Bondly
First customers will be marketplaces that sell digital goods like Domain Names and In-Game items and that support crypto payments already. Existing domain name credentials and ownership will be wrapped in an NFT and swapped for requested crypto directly
Requires that the marketplace itself stakes Bondly collateral as well as each individual marketplace vendor
COMPLETELY UNDERCUTS the whole ‘fake review’ industry which is prominently used to inflate value on sites like Amazon.com
With BPROTECT you can
Give more trust to your buyers that you will provide the purchased asset in a timely fashion
As a buyer you can request sellers to use this method so you have more trust
Sell an asset via OTC that you do not have yet (e.g. waiting for vesting) by staking collateral in the Bondly network
Set up recurring payments from individuals to vendors that can deduct from your account every month, similar to a Netflix subscription completely crypto enabled
How does BOND PROTECT work?
For individual OTC Trades:
Seller stakes collateral and ensures the buyer will receive asset by a specified date or with a specific condition
If agreement is violated, collateral is forfeited and transferred to the buyer
For Marketplace Vendors:
Vendors stake collateral (earning staking rewards for doing so)
Should a vendor violate a sale condition (e.g. not deliver a good on time), BOND collateral is provided to buyers as compensation
Each sale is recorded on-chain for transparency
Vendors who provide extended positive service with a long term history are rewarded through our staking/LP rewards program
As our ‘sibling’ projects Darwinia and Bifrost have realized, Polkadot and using Substrate represents a phenomenal step forward in interoperability. It offers:
Total flexibility for building a cross asset non-custodial token bridge
Seamless integration of our partners/peer bridges between infrastructure
Built in network security
Efficient token standard indexing for every type of asset in every type of blockchain
We don’t have Digital Money without Bitcoin; We don’t have Smart Contracts and DeFi without Ethereum; We don’t have true interoperability without Polkadot and Substrate. In a future article we will talk more about our Kusama testnet release.
Whats next for BONDLY?
BONDSWAP for Ethereum, the first formal product release, will be available soon (so hold off on your OTC transaction until then). This will include support for the Bondly staking program. Detailed roadmaps for the other products will be announced soon! In the meantime we will be making additional articles (but not limited to) the following topics:
10-31 21:07 - 'Share a big wool, hurry up, for the foreign trade field of exchange.' (self.Bitcoin) by /u/re01020102_ removed from /r/Bitcoin within 91-101min
''' Process: To put it simply, more and more Chinese foreign trade companies are using USDT for payment collection and choosing to avoid THE US dollar because of the long payment collection cycle in US dollar, customs clearance fee, wire transfer fee, exchange rate fluctuations, depreciation of US dollar and other reasons.... If you are a newbie and don't know where to buy USDT, you can choose Huobi or [link]1 to buy USDT. At the same time, you need to register [link]2 , which is a exchange service platform for foreign trade enterprises in greater China and headquartered in Hong Kong. Invitation code: RJTGVI. After registration, it will be approved in about two hours, and then you can withdraw your USDT purchased from Huobi or Binance to [link]2 , and choose the highest bidder to sell. After the sale, you will receive USDT Trc20, and you can cash out your USDT Trc20 by selling it through Binance or Huobi.So you've made an arbitrage play. Benefits: The principal is $5,000, which can be exchanged for more than 700 USDT at the current price. The premium of each USDT is $0.1, and the profit of one handling is $70, and the profit of ten handling is $700.An average of eight times a day is enough, because the number of times depends on the order limit of the foreign trade company. The principal is $10,000, and the profit is about $140.Can keep moving bricks every day, the principal of 10,000, a day to earn thousands of dollars 800 no problem.But the premise is, the key, the key, the key -- see the foreign trade company hang sheet immediately make a move to give him, otherwise the premium is fleeting, will be other acceptor to grab sheet. Extension: Conditional, can consider to go to Hong Kong to do an HSBC or standard Chartered account, buy more cheap USDT by means of telegraphic transfer, also can look for tether domestic agent to buy USDT, if such operation can be more comfortable stuffy sound rich, but the premise is to have personal assets proof.The Student Party does not consider this method for the time being, because your principal is small (non-discrimination, please do not be too sensitive, I just graduated three years ago, I worked my ass off to run errands for customs clearance company...).

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain. The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.
The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions. When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved. This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency. Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
1.1 OVERVIEW ABOUT ARYACOIN
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community. Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details. Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda. Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified. Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin. Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim. Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details. Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time. According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public. In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks. AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.
1.1.1 ARYACOIN HISTORY
Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team. Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin. “We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said. Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC. Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees. “We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.” “One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”. “So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.” “We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.”

Business Partner with Simplex Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries. In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020. Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.
1.1.8 HOW DOES ARYACOIN WORK?
Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.
2. ARYACOIN TECHNOLOGY
They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash. For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it. The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.
The steps to run the network are as follows:
New transactions are broadcast to all nodes.
Each node collects new transactions into a block.
Each node works on finding a difficult proof-of-work for its block.
When a node finds a proof-of-work, it broadcasts the block to all nodes.
Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.
2.3 AYAPAY PAYMENT SERVICES GATEWAY:
According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world. This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee. In other similar systems or even systems such as PayPal, money is stored in the user account.
2.4 CONSENSUS ALGORITHM IN ARYACOIN
The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.
2.5 DOUBLE-SPEND PROBLEM AND SOLUTION
One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.
