Solana More Than Triples Transaction Size Limit in Mainnet Upgrade

Solana has upgraded its mainnet to increase the transaction size limit from 1,232 bytes to 4,096 bytes. This upgrade aims to give developers more room for complex operations within a single transaction.

The new limit will allow developers to fit in zero-knowledge proofs and transactions with multiple signatures. The Solana Foundation emphasized that this change is intended to 'do more' with applications such as these by unlocking workloads previously unable to fit inside a single transaction.

This upgrade also introduces the v1 transaction format, which maintains full backward compatibility with legacy transactions. Developers who want to benefit from the size increase will need to update to v1 transactions.
