Last Thursday (December 5), the Ethereum decentralized exchange IDEX released a new DEX based on Rollup technology, a layer 2 scalability protocol that is only available through Ethereum's latest The "Istanbul" hard fork is only possible. By reducing gas fees, rollup-based smart contracts have become a handy scalability tool for IDEX and others. Thursday's move is IDEX's first overhaul since it launched in October 2017. In 2018, IDEX accounted for 3 percent of all gas payments to miners on the ethereum network, totaling $4.3 million, Ahmad said. (CoinDesk)

1. Vitalik responded to "the Ethereum Foundation stopped funding some teams": it was only screened out, and the foundation's funds are sufficient to last for 6 years

Recently, there have been voices in the community saying that the Ethereum Foundation plans to stop funding most internal teams next year, so there has been speculation that the Ethereum Foundation may have insufficient funds. In this regard, Vitalik himself responded in the Chinese community of Ethereum 2.0, saying that the cessation of funding is the result of the foundation's screening, and the funds are currently sufficient.

Earlier news, on December 6, Nina Breznik, a developer who has worked on Ethereum Remix for two years and is currently working on PlayProject, tweeted: "Some of you may already know that the Ethereum Foundation plans to stop supporting most Funding from internal teams. Sadly they decided to stop funding the youngest projects first. So from 1st December our funding has been stopped and funding for other projects will be cut next year."

"It's not a question of lack of money. The foundation's current annual budget is still 30 million US dollars, which is enough to last for 6 years," V God explained, "We have recently screened the internally funded teams, and some of them were naturally eliminated by us. It’s because we don’t want to fund them.”

At the same time, regarding the previously considered method of including a part of the miner's fee into the research and development fund, Vitalik said that this solution can learn from Zcash, but it is best to conduct experiments on Layer 2 first to confirm whether it is feasible. (block rhythm)

2. Nearly 200 People Sign Petition to Release Ethereum Developer Virgil Griffith

So far, 194 people have signed the petition to release Ethereum developer Virgil Griffith. According to previous news, Ethereum Foundation scientist Virgil Griffith was arrested by the U.S. Attorney's Office for the Southern District of New York and the FBI because he intended to transport mining equipment used to manufacture ETH to North Korea, and accused him of violating U.S. sanctions. Since then, V God has also signed a petition to release Virgil Griffith. On Monday, ethereum developer Virgil Griffith was released after a hearing to await sentencing. (Trustnodes)

3. Ethereum supply has dropped 12.6% since the Constantinople upgrade

Since the Constantinople upgrade, in the run-up to the Istanbul hard fork, the new supply of Ethereum mined this year has dropped by 12.6%. It is reported that in 2016, the daily circulation of Ethereum has been stable at 30,800, and dropped to 20,000 in 2018.
