ChainCatcher news, according to official sources, the Solana Foundation has initiated the SIMD-0215 proposal, aimed at scaling Solana's infrastructure to billions of user accounts. This proposal adds a new hash, called "Accounts Lattice Hash."It is reported that the "Accounts Lattice Hash" uses homomorphic hashing to maintain the hash of the entire account state, allowing for quick updates while being secure, enabling:(1) each block to include the hash of all accounts, not just the accounts that changed in that block, and(2) the removal of Epoch Accounts Hash.
