The Solana network has been facing a serious congestion problem in recent days. This led to significant delays in processing times and the cancellation of many transactions. Investors using the popular Phantom wallet app on Solana and other networks have been warned about network congestion. They were informed that they would have to wait longer for their transactions to be completed.

Spam transactions are largely responsible for this congestion problem affecting the network. These transactions are sent by bots to gain priority over the transactions of normal users. The problem is exacerbated by the increasing number of transactions related to newly released meme coins. This creates excessive demand on the network’s block space, preventing access for many users.

In the first quarter of 2024, memecoin activity on the Solana blockchain experienced a significant jump. During this period, the number of new tokens seen on Solana DEXs reached a record level.

This increase in activity, largely driven by meme coins, shows that the network is gaining traction among new investors due to its affordable transaction fees. However, the intensity of spam transactions reduced the performance of the network.

Matt Sorg, technology and product lead at Solana Foundation, made a comparison between Solana’s architecture and the infrastructure of the internet. In Solana’s setup, just like on the Internet, individual validators operate as IP endpoints and servers, processing transactions without using mempools.

Sorg explained that the network sends transactions directly to block leaders, bypassing any staging model or mempool where transactions can be held before being added to the chain. He suggested that an overload of spam transactions could crash this system and, as a result, many transactions could be cancelled.

Sorg stated the following in a blog post: “There is a problem with this transaction in Solana and there is no reliable way for users to include their transactions in blocks. The systems implemented for fees and stake-heavy transactions are not reached.”

The Solana development team strives to create effective solutions in response to these challenges. According to co-founder Anatoly Yakovenko, software patches are in the works, but it will take some time.

Austin Federa, strategy leader at the Solana Foundation, said: “The Solana network is once again being tested with tremendous intensity. Bug fixes will be available over the next week and things will start to improve.”

This existing congestion may extend into the infrastructure of the network and therefore affect users’ ability to interact with the blockchain. In this regard, Anza, the developer of one of Solana’s Agave authenticator clients, will be offering fixes that address specific issues with the QUIC implementation. These updates are expected to improve the performance of the client, especially in high demand scenarios.
