Solana (SOL) plans to introduce a new fee system in addition to a number of other improvements as part of an effort to combat its repeated network problems.
According to a statement released by Solana Labs, Solana suffered a network outage over the weekend when the project’s mainnet beta cluster “stopped producing blocks due to a stalled consensus.”
The outage comes after Solana patched network and performance issues that were previously known in December and January, as well as an earlier outage last September.
Solana Labs says the network has been suffering from “intermittent congestion issues” since early January due to bot activity targeting non-fungible tokens (NFT)-mints. This also caused the recent outage, according to the project.
“A massive amount of incoming transactions (6 million per second) swamped the network, surpassing 100 Gbps of traffic at individual nodes. There is no evidence of a denial of service attack, but instead evidence suggests that bots attempted to programmatically win a new NFT minted using the popular Candy Machine program.”
However, Solana notes that its network continued to function at transaction request levels that were 10,000% of the level that caused the outage in September, an improvement it attributes to upgrades implemented since then.
A new upgrade aims to “implement improvements in memory usage to increase the time that nodes can endure slow or stalled consensus,” according to the project.
Solana is also working on core log mitigation.
“To affect control over network traffic, Solana core protocols are reimplemented on top of QUIC, a Google-developed protocol designed for fast asynchronous communications like UDP, but with sessions and flow control like TCP. Once accepted, many more options are available to customize and optimize data ingestion.”
Additionally, Solana notes that fee prioritization is being worked on.
“Solana’s fee prioritization should only affect the individual state and not the entire block. This creates a system that resembles “neighborhood fees” instead of “global fees”. The subsequent transactions that pay a higher fee but don’t fit into that block because they’ve reached the maximum limits for writing to an account will be spilled and scheduled for the next block, but other transactions that interact with other accounts can it can still be added to the same block even if they pay lower fees.”
