Solana developers have unveiled a groundbreaking proposal aimed at tackling one of the biggest obstacles to blockchain mainstream adoption—scalability. The initiative introduces a lattice-based hashing system that redefines how the blockchain manages and verifies billions of user accounts, addressing the “state growth problem” faced by high-performance blockchains.
Currently, Solana and similar blockchains face challenges in recalculating the state of all user accounts as the network scales. This time-consuming process limits the network’s ability to efficiently manage rapid growth.
The new proposal outlines a solution: homomorphic hashing, an advanced cryptographic method that processes only changed accounts while maintaining the blockchain’s state verification. This innovation allows Solana to retain its 128-bit security level while significantly reducing computational demands.
Key Features of the Proposal
- Efficient State Verification: The new system eliminates the need to recalculate the entire state for every account creation or modification.
- Improved Scalability: The hashing upgrade aims to make it feasible for Solana to support billions of accounts without performance bottlenecks.
- Validator Compatibility: Early implementations by Agave and Firedancer validator clients have demonstrated the system’s practical effectiveness.
According to the proposal’s authors, “The main goal is to scale Solana to billions of accounts and compute a ‘hash of all accounts’ in practical time and space.”

How the Upgrade Works
The Accounts Lattice Hash introduces instant verification without requiring recalculations, effectively solving the challenge described by Solana Labs co-founder Anatoly Yakovenko: “New account creation has to prove that it is new somehow.”
By implementing this lattice-based hashing system, Solana’s blockchain can dynamically update account states while maintaining top-tier security standards.
The upgrade will follow Solana’s formal improvement process, requiring validator approval through network-wide voting. To ensure a seamless transition, developers recommend a phased rollout, enabling nodes to pre-compute the new hashing system before it is fully activated.
Implications for the Broader Blockchain Ecosystem
If successful, this upgrade could set a new standard for blockchain scalability, influencing how other networks address similar challenges. With promising early results, the proposal underscores Solana’s commitment to innovation and its role as a leader in blockchain technology.
