Cryptocurrency has been growing in popularity since its debut, and the Solana network has been making great strides within the industry. Recently, the network experienced disruption due to a large block of data that overtaxed their standard systems.

The disruption took place on February 25th of this year, where the Solana Mainnet Beta Cluster encountered a significant delay in block finality. It began as a presumed clogging within the primary block forwarding protocol—known as the Turbine. Much to the surprise of the team, an excessive amount of traffic was dictated by the Turbine which caused the majority of block data to be transmitted via Block Repair; which is a slower form of delivery.

After continuous analysis, the core engineers successfully identified the issue. The disruption was due to an intricately-sized block which overburdened the validator deduplication filters. The data in the large block was continually reforwarded amongst the validators which only exacerbated the problem as new blocks of data were created.

To rectify the situation, the engineers implemented enhancements to the deduplication filters. This new set of filters allowed for a far greater capacity of unique components before overcrowding, plus improved parallelization of duplicates. The team are also actively developing resilience and adaptable designs with the help of shred forwarding services.

In the aftermath of this episode, the engineers have developed conclusions and are implementing changes for a more efficient network in the future. Moving forward, the Solana network will continue to make great strides with the help of these refinements, allowing for smooth operations when dealing with large blocks of data.
