first_img Arbitrum advances ZK settlement, L1 withdrawals are expected to be shortened from several days to several hours

The Arbitrum development team stated that they are introducing zero-knowledge (ZK) proofs into the Arbitrum platform to achieve a multi-proof settlement model. Through ZK proofs, the settlement time of Arbitrum blocks to Ethereum L1 is expected to be reduced from several days to several hours, while enhancing user, cross-chain bridge, and protocol capital efficiency, and maintaining security through the multi-proof mechanism. Related capabilities are aimed at Arbitrum One and dedicated chains based on the Arbitrum platform. Offchain will subsequently submit upgrade proposals to the DAO.Current progress includes: the ability to run the same state transition functions in SP1 zkVM as in optimistic execution, generating ZK proofs for real mainnet block production; Stylus's WASM contracts can be proven alongside Solidity contracts; the team has launched an independent Rust verifier, making ZK proofs a first-class mode alongside standard verification; the BoLD settlement protocol has supported the acceptance of ZK proofs and is endorsed by a fast confirmation committee, while the original dispute games still serve as a fallback path, forming a multi-proof architecture that coordinates ZK proofs, proof committees, and fraud proofs.The team claims to be continuously reducing proof costs and will gradually merge related code into the Nitro main production path. The next steps include further optimizing proofs and shifting to Reth-based execution, completing L1 message inbox proofs, and integrating ZK settlement capabilities into node configurations for on-demand activation across chains.

Wu Jiezhang: The development of stablecoins in Hong Kong will move forward steadily, and different industries can boldly attempt to combine RWA and Web3

Hong Kong Legislative Council member Wu Jietzhuang posted on X platform, stating that he will continue to promote the development of Web3 in Hong Kong. His views on the future direction of stablecoins, RWA development, and more are as follows:He believes that there will be no significant changes in the development of stablecoins in Hong Kong, which will continue to move forward steadily. The stablecoin regulatory bill was passed in the seventh Legislative Council after a long period of deliberation and discussion. The overall development will align with the international and local financial environment in Hong Kong, progressing steadily, starting with local market trials and aiming to develop the international market, leveraging Hong Kong's position as a financial and innovation hub.RWA is a topic that is currently being discussed extensively in both traditional and Web3 industries. Hong Kong has already promoted a regulatory sandbox, and it is believed that the sandbox will explore the importance of compliant development and the future direction of regulation. It is thought that different industries can boldly attempt to integrate Web3 technology, which is expected to drive the development of numerous real-world applications.The demand for developers is rapidly increasing. More and more companies are setting up in Hong Kong, including Web3 public chains, compliant trading platforms, and underlying infrastructure. The success of developers is closely linked to innovative technology companies, and in the future, efforts will be made to assist the industry in building a talent ecosystem to attract more developers and professionals to settle in Hong Kong.

Arthur Hayes: The acceleration of currency printing is imminent, and investors should boldly increase their holdings in crypto assets

ChainCatcher news, BitMEX co-founder Arthur Hayes stated that the current crypto bull market has just begun, and investors should boldly take a left turn, holding and increasing their positions.Hayes pointed out that 2024 is a crucial year, as several major countries will hold presidential elections. In particular, the United States, where the ruling Democratic Party will do everything possible to secure re-election in order to reverse the Republican policies. In an election year, if the public feels the economy is in recession, the incumbent president's re-election probability will drop from 67% to 33%. Therefore, the ruling party, which controls monetary and fiscal policy, can simply increase government spending significantly to boost nominal GDP growth and create an illusion of no recession.Data shows that U.S. government spending accounts for 23% of nominal GDP, meaning that as long as the government is willing to borrow money, nominal GDP can be manipulated at will. According to the Congressional Budget Office (CBO) forecasts, whether Biden or Trump takes office, the U.S. government's fiscal deficit will continue to expand in the future. Additionally, geopolitical conflicts surrounding the U.S. are escalating, and politicians are eager to continue providing billions of dollars in aid to allies.Hayes emphasized that as long as the government can borrow at rates lower than nominal GDP growth, politicians will continue to increase spending. Therefore, in the future, the scale of money printing will only become more exaggerated. He suggests that investors take full advantage of the recent cryptocurrency price pullback to gradually build their positions. As the summer in the Northern Hemisphere approaches, the volatility in the crypto market will also decrease, making it an excellent entry point for non-pre-sale round investors. Unless real interest rates turn positive, investors should remain optimistic and let the winners continue to run.
