Solana raised its maximum transaction size from 1,232 bytes to 4,096 bytes in a mainnet upgrade, giving developers more room for zero-knowledge proofs and multi-signature transactions. The change lands weeks after the network cut its block time and voted to slow future token issuance.
Solana more than tripled its maximum transaction size, from 1,232 bytes to 4,096 bytes, letting developers fit more complex operations into a single transaction. The increase targets workloads such as zero-knowledge proofs and transactions carrying multiple signatures, which previously couldn't fit inside Solana's smaller size cap.
Upgrade activated at epoch 1,035
The change went live on mainnet on Tuesday, at the start of epoch 1,035 around 1:00 am UTC, according to data shared by the Solana Foundation. The upgrade also introduced a new v1 transaction format that keeps full backward compatibility with legacy transactions.
Existing formats keep working for wallets and applications that don't update. But protocols that want the larger size limit need to adopt v1 transactions to benefit from it.
A Solana Foundation spokesperson told Cointelegraph the upgrade mainly aims to help developers do more with applications such as zero-knowledge proofs, multi-signature transactions, and new onchain signature schemes, unlocking workloads that previously couldn't fit inside a single transaction.
Part of a broader run of network changes
The size increase follows other recent changes to Solana's core performance and monetary settings. In August, Solana cut its blockchain slot time from 400 milliseconds to 350 milliseconds. In June, the Solana Foundation had shared plans to reduce slot times further, to 200ms, arguing the change would improve latency and speed up confirmations on the network.
Separately, Solana validators approved a proposal on Aug. 28 to double the network's annual disinflation rate, reducing future issuance of SOL, the network's native token.
