ChainCatcher reported that the Solana Foundation has officially launched the SIMD-0215 ​​proposal, which aims to expand Solana's infrastructure to billions of user accounts. This proposal adds a new hash, the "Accounts Lattice Hash".

According to the introduction, the "Accounts Lattice Hash" uses homomorphic hashing to maintain the hash of the entire account state, which is both fast and secure, and enables:

(1) Each block contains the hash of all accounts, not just the accounts changed in that block, and

(2) Delete the Epoch Accounts Hash.
