【Solana Foundation Initiates New Proposal to Introduce 'Accounts Lattice Hash'】According to Golden Finance, the Solana Foundation has initiated the SIMD-0215 proposal, which introduces a new hash called 'Accounts Lattice Hash'. This hash utilizes homomorphic hashing to maintain the hash of the entire account state, allowing for quick updates while ensuring security. This allows for: (1) each block to include the hashes of all accounts, not just the accounts that changed in that block, and (2) the removal of the Epoch Accounts Hash. If adopted, it will replace the Epoch Accounts Hash with a grid-based method, enabling efficient, real-time updates of account states without the need to reprocess all accounts.
