Zhou Xiaochuan, Vice Chairman of the Boao Forum for Asia, attended and delivered a speech on issues related to digital currency, stating that in the development ecosystem of digital currency, the digitization of payment systems and the digitization of currency are two sides of the same coin. Secondly, as the digital currency ecosystem develops, some concepts will gradually become clearer, and everyone is also gradually exploring; in fact, concepts are also undergoing integration and upgrading. Currently, the development of digital currency, including the digital renminbi, is still primarily based on account-based digital currency. Of course, token-based digital currency is also a path that may have development space, but the mainstream remains account-based digital currency. Thirdly, it is essential to deeply understand and adhere to the dual-layer operational system. At the same time, Zhou Xiaochuan emphasized the need to uphold principles such as safety, convenience, low cost, and anti-abuse.Zhou Xiaochuan added that cross-border transactions are also one of the important exploration directions for central bank digital currency, involving both technology and systems, as well as policy orientation.

ChainCatcher news, Solana infrastructure startup Helius has launched Solana NFT Compression, allowing developers to mint large quantities of NFTs at a low cost through the Digital Asset Standard (DAS). This is achieved by maintaining the NFT state off-chain with indexing companies like Helius rather than on-chain accounts, ensuring that off-chain and program interactions are legitimate and secure through a verification mechanism.Compression eliminates the need for complete on-chain storage while retaining Solana's decentralization, security, and programmability. The compressed NFTs are stored in the Merkle tree of the Solana ledger and off-chain indexers. These compressed NFTs are not native Solana tokens and do not have token accounts, mint accounts, or metadata; each Merkle tree has an account that can accommodate millions of NFTs, requiring API calls to read any information about the compressed NFTs. All NFT modifications must go through the Bubblegum program, and compressed NFTs can be converted into regular NFTs, but not vice versa.According to the crypto data platform RootData, on October 20, 2022, Helius announced the completion of a $3.1 million seed round financing, led by Reciprocal Ventures and Chapter One, with participation from Solana Ventures, Alchemy Ventures, Big Brain Ventures, Propel VC, and angel investors including Magic Eden co-founder Zhuoxun Yin and Squads co-founder Stepan Simkin.
