Solana V1 transactions hit testnet, aiming to fold multi-step operations into one

On September 1, Anza initiated Transaction V1 on the testnet of Solana, allowing for the final rehearsal of this upgrade prior to its launch on September 9.

The change is intended to allow cryptographic and DeFi workloads that had initially to be fragmented in different transactions to now be processed in one single atomic transaction, as stated by Solana Compass.

Jobs that used to be split now fit in one call

The most notable alteration is the increase in space. The maximum size of a Solana serialized transaction has increased from 1,232 bytes to 4,096 bytes which is an increase of 3.3 times and took effect at the testnet epoch 1025.

According to the website dedicated to Solana Foundation’s large transaction update, such large transaction size will make it possible to implement zero-knowledge proofs, large multisig transactions along with various signature schemes which were unachievable within one transaction.

In turn, fewer transactions have to be processed, less money is required to pay for signatures, and there is no need to wait for a chain of confirmations. BLS signature schemes, as well as confidential transactions and multisig setups will benefit from this upgrade.
