[News Flash] The latest developments in the blockchain field: Optimistic proofs and ZK proofs are competing to become mainstream. Both technologies are solving the scalability problem of blockchain to achieve a more efficient consensus mechanism. On the other hand, the complexity of the ZK airdrop rules has sparked widespread discussion, but this has not prevented its development in the market. At the same time, API3 provides oracle services in an innovative way, with data provided directly by the data source without the need for third-party aggregation and transfer. Ethereum is also constantly evolving, and the Dencun upgrade introduces a state expiration function to solve the problem of historical data storage and access. Finally, BitMEX co-founder Arthur Hayes predicts that the Dogecoin ETF is coming, which will further promote the attention of memecoin in the market.
