The Solana Foundation has initiated the SIMD-0215 proposal, aimed at enhancing the scalability and efficiency of the Solana network by introducing 'Accounts Lattice Hash.' This proposal utilizes homomorphic hashing to maintain the hash of the entire account state, providing fast updates and high security. Specifically, this proposal can achieve the following points:
1. Each block contains the hash of all accounts: Unlike the current system, the new system allows each block to contain the hash of all accounts, not just those that have changed within that block. This helps to track account states more comprehensively, improving data integrity and consistency.
2. Removal of Epoch Accounts Hash: By introducing 'Accounts Lattice Hash,' it can replace the existing Epoch Accounts Hash, thereby simplifying the management of account states. The Epoch Accounts Hash is a resource-intensive process, and the new system reduces the computational burden by only updating the accounts that have changed.
This point-based approach allows for efficient, real-time updates of account states without the need to reprocess all accounts. This method is akin to only cleaning a dirty room rather than sweeping the entire house every day. This improvement will help the Solana network scale better to billions of user accounts.
