Today, MakerDAO co-founder and CEO Rune Christensen said on Twitter: "I apologize to those who were hurt because I once claimed that there would be no Chainlink without Maker. Obviously this statement is too exaggerated. But I hope Chainlink The community can look at the negative information in different posts and reconsider whether this is a good marketing strategy. Maker pioneered the medianizer (medianizer) decentralized oracle design and off-chain aggregation design, and Chainlink also adopted this Both designs, and undeniably benefit from the ability to notice what Maker has released. I certainly have no problem with that, in fact that's what open source and blockchain are all about. But I just don't understand why the Chainlink community is so Years of targeting Maker with attacks, lies, and hate...all for the 'crime' of continuing to use the longest running decentralized oracle network in the world. Someone really wants a single oracle monopoly running all Top DeFi protocol? Wouldn’t it be better to have such a diversity of critical infrastructure?”

Ernst & Young announced the launch and open source of Nightfall 3, a layer-2 solution for Ethereum, which uses the ZK-Optimistic Rollup mechanism to combine zero-knowledge proof (ZK or ZKP) with a new model for transaction verification to improve efficiency and reduce transaction costs. In order to ensure that only correctly formed layer 2 blocks are included in the final blockchain record, users are economically incentivized to challenge incorrect blocks. When a challenge is made, the smart contract will arbitrate the accuracy of the challenge and reward the correct one. And delete the incorrect blocks. According to Ernst & Young, using ZK-Optimistic Rollups, Nightfall 3 can achieve a cost of about 8200 Gas per transaction while maintaining privacy, which is one-eighth of the cost required for public ERC20 token transactions. In addition, Nightfall 3 also provides developers with a standardized application programming interface (API) similar to other token trading tools, reducing the learning curve required for developers to achieve privacy.
