Solana's Agave 4.0 Upgrade Enhances Network Performance

Solana's core development team, Anza, announced that the Agave 4.0 upgrade has been officially deployed to mainnet validators. According to Foresight News, this version introduces several performance enhancements, including significantly reduced network transmission latency and a unified transaction submission protocol using QUIC. These improvements aim to increase block capacity and lay the groundwork for higher throughput on Solana. Key updates include the introduction of XDP technology, which reduces Turbine retransmission latency from 600ms to approximately 0.8ms, supporting the development of 100 million compute unit blocks. The transaction submission method now exclusively supports QUIC, removing the UDP entry. The replay stage has been asynchronously optimized for faster processing. Additionally, voting transactions no longer use a static CU cost model, freeing up more block capacity. During this version cycle, several features will be activated, including p-token, which releases about 13% block capacity, Stake Program v5, which raises the minimum staking threshold from 1 lamport to 1 SOL, support for SBPFv3 programs, and BLS12-381 system calls.
