Solana released a new proposal titled Solana Improvement Documents (SIMDs -215) on 6th January, 2025. This project aims to scale Solana to billions of accounts and provide high-quality documentation for its Ecosystem.
According to the proposal, it aims to compute a “hash of all accounts” in practical time and space, improving access to Solana. Currently, there are two main kinds of account hashes used in Solana.
The Epoch Accounts Hash and The Accounts Delta Hash and both of these hashes have limitations that make scaling challenging due to the amount of data required.
Solana Labs Co- Founder, Anatoly Yakovenko, had addressed the state growth problems on his X account on May 11th, 2024.
In his words, “To solve the state growth problems, new account creation has to actually create new accounts. This means that a new account has to prove that it is new somehow”.
He further explained that this is important to do if the runtime has a full global index of all the accounts. But that way of proving that the account is new is expensive.
Anatoly proposed that in two years, he expects about 20-30 Billion users and then a cold/hot cache for account management might be the only necessary thing to use.
With this new proposal, SIMD – 215 highlights that The Accounts Lattice Hash Upgrade will eliminate the need to recalculate all the states, with the introduction of instant verification.
The homomorphic hashing element would also allow the Solana Network to update its state verification by processing only changed accounts.
As of today, DefiLlama, records that daily trading volume across Solana-based DEXs neared $3.8 billion beating Ethereum and Base, Ethereum’s most popular layer 2 scaling network by 43%.
Crypto Enthusiasts predict that if this proposal is implemented and accepted, it could improve the speed and efficiency of the Solana Network significantly.
