Solana solves some congestion issues on the blockchain

By KMatt | Blogging Crypto | 23 Apr 2024

The Solana blockchain, based on Proof of History (PoH) and staking, has implemented some updates to alleviate network congestion issues.
According to MainnetBeta validators, the v1.17.31 relaunch is now recommended for general use.
This patch contains improvements that will help alleviate some of the ongoing network congestion and will be followed by additional improvements in v1.18.

The Solana blockchain is known for its speed and low transaction costs, thanks to the use of PoH and staking.
However, the network has experienced periods of congestion, particularly due to the increase in transactions related to memecoins and other tokens.
These congestion issues have led to an increase in the failure of non-voting transactions, with the rate reaching 70% in recent weeks.
The causes of the congestion are multiple, such as the increase in bot trading transactions, some memecoins which have generated a wave of low-value transactions, clogging the network.


Fixes implemented by the v1.17.31 update include:

- Improvements to the Mempool, i.e. the cache where transactions waiting to be validated are stored. The update optimizes Mempool management, prioritizing the most important transactions and reducing latency.

- Sealevel optimization. Sealevel is a Solana implementation that allows you to execute transactions in parallel across multiple shards. The update introduces improvements to coordination between shards, increasing overall efficiency.

- Block size reduction: Block size has been slightly reduced to reduce network congestion and improve transaction propagation speed.

The developers are already working on further updates for v1.18 which will include:

- Turbine implementation: Turbine is a layer-2 protocol that aims to improve the scalability of Solana through off-chai transaction aggregation.

- Solana VM optimizations: The Solana Virtual Machine (VM) will be optimized to improve efficiency and reduce transaction costs.

- Greater decentralization of the network: the aim is to increase the number of validator nodes to better distribute the load on the network and make it more resilient.

Despite recent problems, Solana remains a promising blockchain with great potential, with developers actively working to improve the network and make it even more scalable and efficient.
