Solana developers have proposed a new hashing system to improve network scalability amid a growing user base. The proposal, titled SIMD-215, introduces a lattice-based homomorphic hashing function that alters how the blockchain verifies and traces user accounts. The primary objective is to enable Solana to handle billions of accounts while efficiently computing a ‘hash of all accounts’. Currently, the network faces challenges with the ‘state growth problem’, where nodes must recalculate the state of all accounts regularly. Co-founder Anatoly Yakovenko explained that proving new account creation necessitates a full global index, making the process costly. The Accounts Lattice Hash upgrade seeks to eliminate the need for recalculating all states by enabling instant verification and processing only altered accounts, akin to tidying up only messy spaces in a house. If implemented, this upgrade could enhance the speed and efficiency of Solana, which has recently generated 43% more trading volume across its decentralized exchanges compared to Ethereum.
