Solana Transaction V1 Upgrade Set for September 9
Solana's upcoming upgrade will significantly increase its transaction limit to 4,096 bytes on September 9. This is about three and a half times the current limit of 1,232 bytes.
According to Jacob Creech, Solana Foundation vice president, several network changes are planned, including Transaction V1 and rent reductions. The new format will allow for larger transactions, potentially supporting zero-knowledge proofs, complex multisignature instructions, and other data-heavy operations.
Developers must opt-in to the V1 format, while existing legacy and version-zero transactions will remain valid.
Solana is also targeting faster slots with a cut in target slot time to 350 milliseconds. The network plans five rent-reduction stages that could eventually cut the calculation from 6,960 to 696 lamports per byte.
