I found that ViaBTC launched the cloud mining service again, and can purchase BTC & ETH contracts.

The prices are reasonable and from their official press release, they said that there's referral rewards and discounts. Second market trading will also be supported later.Sounds good and may give it a try?

OneSwap will be officially launched along with the public beta from September 7–10 (UTC). All qualified participants in the open beta will receive an airdrop of ONES token.

OneSwap is a fully decentralized transaction protocol on smart contract, with permission-free token listing and automated market making (AMM). Known as the “upgraded version of Uniswap”, OneSwap has comprehensively upgraded the user experience based on Uniswap’s AMM, offering a trading experience equivalent to that of a centralized exchange.

OneSwap adopts the AMM liquidity mining and transaction mining model. It has also introduced an on-chain order book so that users can initiate either Swap orders at the market price or limit orders which enable the buy and sell order at a target price.

OneSwap will charge the Taker a fixed percentage of transaction fees based on the transaction amount, while Maker does not need to pay; transaction fees are divided into two parts, 60% directly goes to the liquidity provider and 40% for repurchasing and burning ONES. In transaction mining, both liquidity providers and traders will receive OneSwap’s governance token ONES as an economic incentive.

Duration of public beta: 13:00 PM September 7–13:00 PM 10, 2020 (UTC)

On March 27, Vitalik tweeted: "Things Ethereum has in 2020 that it did not in 2017." He mentioned DeFi products represented by Uniswap as well as MakerDAO and Loopring as the benchmark of different types of DEX.

Up to now, the trading volume of DEX in August has exceeded US$9 billion, an increase of 197% from July. Uniswap, in particular, contributed the biggest share of 55.3%, closely followed by Balancer (16.5%) and Curve (15%).

Amid the rush, the Uniswap has launched the ERC20/ERC20 liquidity pool, automated market maker (AMM), oracle and lightning exchange functions; and the order book-based Loopring has also been strongly recommended by Vitalik and the Ethereum community. They both advance triumphantly in their respective segments. Yet efficient as UniSwap is, its AMM is faced with such defects as slippage, and the convenient Loopring order book is quite sensitive to market liquidity. Market opinions on the two are mixed.

So if there were a product integrating advantages of the two by offering efficient transaction protocols between CEX and DEX and enabling high-speed circulation, and it would be the next hotly contested platform. OneSwap, backed by CoinEx, will be the one.

Being the first with comprehensive advantages, OneSwap has made a breakthrough in DEX!

Investors worldwide have long been suffering from the slow transaction processing and high transaction fees of Ethereum. Also, driven by investors’ vision and strong demand for an innovative DEX, OneSwap was designed to introduce an on-chain order book based on AMM that supports both market orders and limit orders. In this way, users can buy and sell orders according to the target price. In addition to permission-free token listing and automatic market making, OneSwap further improves user interaction through the built-in OneSwap Wallet and allows the deployment of all smart contracts. OneSwap is a master of diversified advantages, committed to providing users with a fresh new experience of DEX.

OneSwap's new architecture design after in-depth research

Having gone deep into the AMM project model in the industry, OneSwap bases itself on Uniswap's Constant Product Market Maker (CPMM) and also supports transactions between all tokens that meet specific standards; under the CPMM model, it is expected when the remaining liquidity providers create a fund pool for two assets, they will create a specific fund pool by investing an appropriate amount of the two assets based on the current market price. For example, when the ETH to USDT ratio stands at 1:350 in the market price, the ratio between the amount of ETH and USDT injected into the fund pool will also be maintained at this level, say, 10ETH:3500USDT. Users can inject liquidity into OneSwap's fund pool of the trading pair with their idle digital assets, and then earn transaction fees as liquidity providers.

Each fund pool in OneSwap comes with an equity token, and users who inject liquidity into the fund pool will receive the corresponding equity token as a proof of equity to withdraw the funds. When each fund pool responds to the exchange transaction request, the product of the two tokens x and y in the fund pool remains a constant: x*y=k. This formula is easy to understand as it represents a situation where no transaction fees are charged. Beyond that, k in the CPMM model will keep rising.

It is worth mentioning that OneSwap has also introduced an "order book" model which allows users to initiate both market orders and limit orders. When processing a market order, the Pair contract will compare the optimal price in the order book with the AMM price, and try to respond to the transaction request at the best price. Part of the market order that cannot be traded will be processed in time through the CPMM model. Limit orders that meet the conditions will be processed timely based on the price fluctuations of the CPMM. Pending orders are temporarily saved in the on-chain order book for the next processing. Everything centers on users’ convenience for setting the best deal.

When liquidity providers inject digital assets such as ETH into the fund pool, the Pair contract will return new tokens based on the current total amount of the fund pool, the total amount of equity tokens that have been issued, and the amount of funds injected this time. When they want to withdraw the original digital assets, they can go through the above process.

Besides, the OneSwap #DevelopmentTeam  has meticulously improved the data structure for the Pair contract, controlling the transaction gas consumption to the same level as in UniswapV2 or even less under certain circumstances. That makes for an upgraded version of UniSwap with negligible transaction fees.

Besides its market-making engine and order book, OneSwap is also equipped with important modules as follows:

I.Router protocol
For the calculation of AddLiquidity and RemoveLiquidity funds;

II.Token issuance and management modules
For the issuance of ONES and for airdrops and burns. Even if the logic of market making and order book is upgraded, the original logic of the token remains unchanged; OneSwap is also equipped with token issuance and management modules where users can edit general authority such as the name, total amount, additional issuance, burning, and freezing, as well as lock-up and C2C functions;

III.Token repurchase module
For withdrawing the transaction fees as revenues to the project developer (non-liquidity provider) from each pair. These revenues are for repurchasing and burning ONES;

IV.On-chain governance
Any address with a voting share greater than 1% can initiate a proposal, and the execution of the proposal is under control of the on-chain logic; opinions on the text are solicited through the voting system, a reflection of its commitment to decentralization;

V.Lock-up module
For saving the ONES held by the project developer and releasing it regularly;

OneSwap's new community governance concept and incentives

The OneSwap project was initially implemented and deployed on Ethereum. To facilitate on-chain governance and encourage community development, OneSwap on Ethereum will issue ONES, an ERC20 governance token, for liquidity mining, transaction mining, and on-chain governance voting, and meanwhile, support the transfer of ownership and a blacklist mechanism. The total amount of ONES is constant at 100 million, of which 50% is used as a community fund to support the construction of the OneSwap ecosystem and 50% is owned by the OneSwap team. 5% of the total ONES owned by the team will be unlocked initially, and the rest will be unlocked at a rate of 5% every six months until all is unlocked after four and a half years.

Efficient and transparent on-chain governance solution

Operations of the governance agreement can be carried out through proposals that will be voted in the community. Users with a sufficient amount of ONES tokens (more than 1% of the total tokens) can initiate a proposal, and any user who holds ONES can vote for or against the proposal. The voting lasts for three days, with one token for one vote. Proposals receiving the majority of votes prevail.

To ensure the transparency and credibility of OneSwap, part of the ONES in the community fund is managed by the governance agreement, and the ONES held by the team is unlocked by the lock-up agreement. 50% of ONES, upon creation, will be immediately transferred to the governance agreement, and the other 50% to the lock-up agreement. According to the unlocking rules, the lock-up agreement will immediately release 5% of the total ONES to the OneSwap team.

After receiving the initial tokens, the OneSwap team will initiate OneSwap's first proposal: applying for ONES, as appropriate, from the community fund to support "transaction mining" and "liquidity mining", with the application amount set as the proposal parameter. Both users who inject liquidity into the fund pool and users who trade with it have the opportunity to gain ONES as incentives.

ONES repurchase and burning

OneSwap charges the Taker a fixed percentage of transaction fees based on the transaction amount, while the Maker does not need to pay. The transaction fees generated in the Pair contract are divided into two parts: 60% directly going to liquidity providers and 40% for repurchasing and burning ONES. In response to market dynamics, OneSwap allows users to change the transaction fee rate within a certain range.

OneSwap will be deployed on various public chains

Exchanges from UniSwap to OneSwap are all trying to provide liquidity as much as possible for digital assets, whether by creating prices in a market in short of liquidity or by accomplishing the blockchain mission in a safe and decentralized manner. The success of Oneswap is clear in sight. It is based on the Ethereum ecosystem at present, and will be launched on multiple mainnets such as TRX and EOS for the convenience of various communities and even global users.

OneSwap has already seized the first-mover advantage in 2020. It is gaining momentum to rival UniSwap, and is bound to be the most important part of DeFi. Stay tuned.

The black swan event on March 12 dealt a heavy blow to the crypto world as the value of DeFi pledged tokens fell from US$1 billion to only US$50 million. Fortunately, soon after the liquidity exhaustion in March, the DeFi market revived when COMP ushered in a DeFi rush by its liquidity mining, and went viral overnight.

DEX stands out in the DeFi field. As the driving force of DeFi and Ethereum, DEX enjoys an ROI 4 times higher than platform tokens of centralized exchanges, and at the same time has created many myths of hundred-fold value increases. Driven by the huge profits, a flood of investors have aimed the DEX sector. Now follow me to experience the wonder of DEX.

I.DEX That Braves the Tides

DEX is nothing new. After the slump in the Bitcoin due to the theft of 850,000 Bitcoins from Mt.Gox in 2014, the market started to realize the risks facing centralized exchanges, and the DEX solution emerged in response. By reshaping the exchange in a decentralized way and allowing users to keep custody of their own private keys without centralized asset custody, DEX proves to be a natural solution to all the security risks underlying in centralized exchanges.

During the development of DEX, from the Bitshare decentralized exchange at the very beginning, to EtherDelta, the first generation of Ethereum decentralized exchange, and to the Ox-based open-source protocol, DEX remained a niche market and struggled to expand due to such factors as low transaction efficiency and insufficient liquidity. Yet the story has changed upon the emergence of UniSwap.

The Historic Turning Point from OrderBook to AMM:

In the past, DEX adopted the OrderBook mechanism, similar to the centralized exchange. However, due to the poor efficiency in on-chain transactions and a small user base, it was difficult to match users’ buy and sell orders. The AMM model (Automatic Market Making) has resolved the painful realities in the OrderBook-based DEX by bringing together liquidity and making the market according to a certain mathematical algorithm. In this way, it ensures stable asset liquidity, and allows all users to provide liquidity and enjoy dividends from the transaction fees of the exchange. The AMM-based DEX represented by UniSwap has embarked on a journey of crazy growth.

According to data from ETH Gas Station, UniSwap has paid a total of US$7 million in transfer fees in the past 30 days, 25% higher than the total transfer fees of Ethereum. Each transfer fee in UniSwap consumes an average of 125GWEI, and a total of 17,700 ETH has been paid. That means over 140 billion transactions have been made on UniSwap in the past 30 days, pushing UniSwap to the supremacy in DEX.

The success of UniSwap has been a shot in the arm for the entire DEX world. The total trading volume in the first half of 2020 exceeded US$3 billion, compared with the figure of only US$2.4 billion throughout 2019. The trading volumes of IDEX, UniSwap, 0x, and Bancor have increased by 144%, 109%, 44%, and 112% respectively, quarter on quarter. It is worth mentioning that the DEX exchange has outperformed Kraken and Coinbase, two established centralized exchanges.

We are embracing an era of DEX, and it is no longer a fantasy to expect DEX to surpass CEX.

II.A White-hot Competition in DEX

The explosive growth of UniSwap has revealed the great power of AMM in front of capital ventures, institutions, and project developers. The huge daily trading volume of UniSwap has attracted numerous investors who want to grab a share of the big pie, and various types of Swap have sprung up. Linch, an on-chain aggregation trading platform, for example, copied and modified some UniSwap source codes, and launched the automatic market maker (AMM) Mooniswap. Apart from UniSwap, which is an overseas project that is more friendly to users abroad, some Swap applications targeting the Chinese domestic market have been unveiled, represented by JustSwap.

JUST is the first project released on the TRON network. With the popularity of UniSwap, Justin Sun launched the TRON version of UniSwap——JustSwap. Promoted by Justin, JustSwap has gained unprecedented fame, but unfortunately, its debut was a crushing failure.

As JustSwap applied no review for token listing just like UniSwap, counterfeit tokens proliferated, such as numerous fake Ethereum. What was worse, on the very night when JustSwap went online, many tokens with the same name were launched, baffling investors and incurring huge losses. More ridiculously, a project named looprex had its logo misused by others in advance, depriving the real looprex of its own trademark ownership.

It is evident that AMM-based DEX represented by UniSwap has solved the liquidity issue and thus entered the fast lane. Since its launch, UniSwap has witnessed an exponential increase in its user base, yet accompanied by drawbacks.

For example, the most notorious flaw lies in its poor trading experience. The AMM-based DEX completely abandoned the OrderBook mechanism. As a result, users, especially market users who prefer to trade limit orders, cannot trade limit orders in AMM projects like they do in centralized exchanges, but trade at the market price set by AMM upon the transaction. At the same time, the lack of OrderBook has led to large slippage when processing large transactions, leaving users unable to settle the deal at a satisfactory price. In addition, the congested Ethereum network has further pushed up the transaction fee of the AMM-based DEX. UniSwap, for example, costs more than ten dollars for each transaction.

The AMM-based DEX appears inferior by comparison with centralized exchanges in terms of trading experience, the biggest obstacle in its expansion. Feeling the pressure from increasing competitors, newcomers after UniSwap are working to create DEX that can rival centralized exchanges in trading experience. A significant change has been simmering in the DEX market layout.


III.New Swap Redefines DEX

Compared with UniSwap with a poor user experience, OneSwap, which concentrates on improving user experience, has come under the spotlight. Dubbed an upgraded version of UniSwap, it has comprehensively enhanced its user experience on the basis of UniSwap’s automatic market making, and is now as user-friendly as centralized exchanges.

What advantages does OneSwap have over UniSwap?

1. OrderBook

Without Orderbook, users of UniSwap couldn’t place limit orders like in a centralized exchange, but passively accepted the price set by the algorithm. If they wanted to buy tokens at a specific price, they had no options but wait till tokens at such a price appear, a waste of time.

OneSwap has tackled such a painful weakness of UniSwap by introducing the on-chain OrderBook based on AMM. Its users can place a market order or limit order at the target price, and leave them automatically executed. The integration of AMM and OrderBook not only provides users with a familiar way of trading limit orders, but also further enhances the liquidity of digital assets.


2.The candlestick chart and depth map

UniSwap has been criticized for its simple transaction interface with a cryptocurrency exchange section only, not even the basic candlestick chart. For professional traders, in particular, it is difficult to see the key trading information and price trend changes, greatly compromising the trading experience.

To benchmark against the centralized exchange in terms of user experience, OneSwap has introduced functions such as the candlestick chart, order ticket, and depth map. Just like centralized exchanges with professional charts, OneSwap provided the price trend, trading volume, depth, and other information of different cryptocurrencies for users to set out informed trading plans.

3.Liquidity mining + transaction mining

UniSwap allows everyone to make market and share transaction fees of the platform by injecting liquidity. The AMM model is believed to be the catalyst for the explosive growth of UniSwap. With an additional incentive mechanism of transaction mining besides liquidity mining, OneSwap leaves more core benefits to its users.

OneSwap will charge the Taker a fixed percentage of transaction fees based on the transaction amount, while the Maker does not need to pay. The transaction fees are divided into two parts: 60% for liquidity and 40% for the repurchase and burning of ONES, OneSwap’s governance token. In transaction mining, both liquidity providers and traders will receive ONES as an economic incentive.

Speaking of OneSwap's governance token ONES, let's talk about its role in the OneSwap ecosystem and how it captures value.

1. Ecological governance rights

On-chain governance involves proposal initiating and community voting. Users with a sufficient number of ONES (more than 1% of the total) can initiate a proposal, and anyone holding ONES can vote for or against it. The voting lasts for three days, following the one-coin-one-vote counting rule. After the voting ends, the proposals receiving more positive votes than the negative are passed.

2. Extreme deflation effect

Of the transaction fees generated on OneSwap, 60% directly goes to the liquidity provider, and the remaining 40% will be spent on repurchasing ONES, in the secondary market, which will be burned through smart contracts. For such a deflationary token, the sharply increasing trading volume of OneSwap entails more and more transaction fees and ONES to be burned. With fewer ONES left in the market, the purchase demand will remain robust relatively, stimulating the token price to grow continuously.

A promising future for OneSwap

The success of UniSwap has led the DEX boom, which has developed into a new force that cannot be ignored in the crypto world. As DeFi grows, DEX will embrace a new stage of development. Yet as UniSwap has revealed many of its drawbacks, of all the emerging Swap applications, which will be the ultimate king of DEX?

The emergence of OneSwap has aroused market expectations as well as attention. In terms of trading experience, OneSwap redefines DEX and is the first DeFi project dedicated to making DEX comparable to CEX by user experience. What miracles will OneSwap create? Stay tuned.
