Recently, the Solana network has faced congestion issues due to a surge in spam transactions, which has prompted developers to come up with various solutions.
Solana developers are solving the congestion dilemma that users are struggling with due to noticeable delays and transaction interruptions, especially on the Phantom Wallet app and other platforms. The root cause of this congestion is the influx of spam transactions, which is exacerbated by a surge in memecoin-related activity that strains the network’s block space and hinders regular user access.
In the first quarter of 2024, we saw a notable increase in memecoin activity on the Solana blockchain. This reflects growing interest from new and retail users, attracted by the network’s cost-effective transaction fees. However, the surge in spam transactions became a bottleneck for Solana’s operations.
Solana Foundation’s Matt Sorg likened Solana’s architecture to the Internet, emphasizing its decentralized transaction processing system. Unlike traditional setups that use mempools, Solana passes transactions directly to the block leader, potentially leading to transaction deletion in case of heavy spam load.
Accordingly, the Solana development team is actively devising solutions, including software patches. Solana co-founder Anatoly Yakovenko expects improvements with bug fixes being released next week.
Anza, developer of Solana’s Agave validator client, also addresses specific issues within the QUIC implementation to improve performance under high request volumes.
The 1.18 update, scheduled for April, aims to make transaction scheduling more deterministic, streamlining processing and alleviating bottlenecks. Additionally, as highlighted in a March blog post from Solana Labs, implementing preferential fees across Solana applications will alleviate delays and improve user experience.
