Solana more than triples transaction size limit with mainnet upgrade

Solana raised its transaction size limit to 4,096 bytes, giving developers more room for zero-knowledge proofs and transactions with multiple signatures.

Solana raised its maximum transaction size from 1,232 bytes to 4,096 bytes to allow developers to fit more complex operations into a single transaction, including zero-knowledge proofs and new onchain signature schemes.

The upgrade was activated on mainnet on Tuesday at the start of epoch 1,035 around 1:00 am UTC, according to blockchain data shared by the Solana Foundation.

The upgrade also introduced the v1 transaction format, which maintains full backward compatibility with legacy transactions. Existing transaction formats continue working for applications and wallet providers, but protocols that want to benefit from the size increase need to update to v1 transactions.

A spokesperson for the Solana Foundation told Cointelegraph that the upgrade mainly aims to help developers “do more” with applications such as zero-knowledge proofs, transactions requiring multiple signatures and new onchain signature schemes, by unlocking workloads that previously couldn’t fit inside a single transaction.

In August, Solana reduced its slot time from 400 milliseconds to 350ms. In June, the Solana Foundation shared plans to reduce slot times from 400ms to 200ms, arguing that it would improve latency and accelerate confirmations on the blockchain network.

Solana validators approved on Aug. 28 a proposal to double the network’s annual disinflation rate, reducing future issuance of Solana (SOL), the network’s native token.
