Ethereum's Top DEX Announces Update Powered by ‘Unbounded’ Scaling Solution

IDEX, the top decentralized cryptocurrency exchange for trading ERC-20 tokens on the Ethereum blockchain, has announced a new update powered by an ‘unbounded’ scaling solution called Optimized Optimistic Rollup (O2R).

The scaling solution is coming at the time of the Istanbul hard fork, which is expected to take place over the weekend but isn't denpendent on it. Istanbul brings six Ethereum Improvement Proposals (EIPs). One of these is EIP 2028, which reduces the gas fee for requesting call data from 68 gas per byte to 16 gas per byte. Calldata, CoinDesk reports, is information broadcast on the ETH state necessary for creating specific smart contracts.

These include smart contracts to bundle on-chain transaction off-chain. Aurora Labs, the company behind IDEX, sees Istanbul as a potential way to lower operating costs while processing more transactions. Alex Wearn, IDEX’s co-founder and CEO, said in a press release:

We designed O2R as a way to solve for Ethereum’s scaling challenges today by offering an alternative system that gives businesses a platform to scale to their needs. For IDEX, this 2.0 release gives traders what they want most—the performance and scalability of a centralized platform combined with the security of a DEX

The release notes each settlement transaction processed using the Optimized Optimistic Rollup solution will consume less gas than a single transaction on the IDEX 1.0 exchange, allowing for significant savings on gas fees. A demo version of the IDEX 2.0 trading platform is now available for traders, and comes with a trading competition that the exchange claims will be distributing over $200,000 in prizes.

It’s worth noting that according to Etherscan data, IDEX was responsible for nearly 28% of all transactions conducted on decentralized exchanges on the Ethereum blockchain over the last 30-day period. Uniswap came in first place with 28.9% of transactions, with Kyber Network coming in third with 17%

Decentralized Exchanges

Decentralized trading platforms are a growing trend in the cryptocurrency space. While the first prominent decentralized exchanges were on the Ethereum blockchain, there are now some available on various blockchains, allowing users to trade directly from their wallets.

Allowing users to trade directly from their wallets means there won’t be a risk of losing funds if a centralized platform gets hacked. This has long attracted users, so much so even decentralized exchanges have launched decentralized trading platforms.

These include controversial South Korean trading platform Bithumb, and its Bithumb DEX, popular exchange Binance and its DEX, Poloniex and its TRON-focused DEX launched shortly after it spun out of Circle, and platforms like Waves, which is partly known for its DEX.

As CryptoGlobe reported, OKEx has also announced that the development of its own blockchain, OKChain, is in its final testing phase. OKChain is going to be used to support the unbanked by “providing them basic financial services.” The first decentralized application on the network will be a decentralized trading platform, OKDEX.

OKB, OKEx’s native token, is set to be equipped with more use cases in different fields, including cybersecurity, finance, lifestyle services, and more.

Update: This article has been updated to reflect IDEX's scaling solution wasn't dependent on Ethereum's Istanbul hard fork.

Trans-Fee Mining Crypto Exchange 'FCoin' Insolvent After Mistakenly Being Too Generous

One of the first cryptocurrency exchanges to adopt the controversial trans-fee mining (TFM) model, which has been called a “disguised ICO” has paused trading and withdrawals over a shortage of crypto worth up to $130 million.

According to a statement published by FCoin’s founder Zhang Jian, a former Huobi CTO, the exchange is now unable to process withdrawals as its reserves are down by between 7,000 to 13,000 bitcoin, worth over $130 million at press time, over an issue that’s “a little too complicated to be explained in a single sentence.”

Zhang’s statement details the cryptocurrency exchange wasn’t hacked, nor is it pulling an exit scam on its users. He detailed that an internal system error gave users more mining rewards than they should have received, noting the error wasn’t detected for a long period of time.

The transaction-fee mining model, which saw FCoin’s trading volume surpass $5 billion per 24 hours numerous times, sees the cryptocurrency exchange incentivize trading via its own token, FT. FCoin reimbursed users for transaction fees paid in BTC or ETH with FTs until 51% of the coin’s supply was distributed, and redistributed 80% of the BTC and ETH it collected to those holding FT tokens.

The controversial model drew criticism and saw Zhang defend it, claiming it was a misunderstood invention. At the time, he said:

If you look back at history, all new things were not recognized at the beginning. Many were believed to be fraud. Jack Ma was recognized as a fraud when he first promoted the internet in China.

Various cryptocurrency exchanges started adopting the TFM model shortly after, with research showing these platforms had unusually thin order books and low traffic taking into account the trading volumes they had.

According to Zhang, the errors in FCoin’s system gave away too many tokens in mining rewards from mid-2018 to mid-2019, when a complete back-end auditing system was implemented. As throughout 2019 the price of FT kept on dropping, Zhang and his team reportedly used their own funds to buy back tokens and drive up demand, a decision he claims was an error.

This, as it gave users a chance to sell their FT tokens and withdraw as much as possible from their accounts, while FCoin bought up tokens that kept on losing value. Zhang’s announcement came shortly after FCoin suspended its platform over a risk-control issue.

Zhang is now reportedly manually processing users’ withdrawal requests sent via email. The founder of the exchange claimed he will “switch tracks” to start again, and noted he hopes he can use the profits made from new ventures to “compensate everyone for their losses.”
