After A Series Of Outages, Solana Developers Unveil A Massive Plan To Improve The Network’s Resilience

  • The blog went on to say that the main cause of the excessive memory use was insufficient votes landing to finalize older blocks, prohibiting abandoned fork cleanup. The downtime led SOL’s stock to drop over 13% to $82, however it has since recovered to $85.73 as of this writing.
  • Fee prioritization will also be available in Solana, starting with the v1.11 release. Unlike Ethereum costs, which are applied to the entire block, Solana’s charge is applied to a single state. As a result, following transactions that pay a greater fee but don’t fit within the current block will be spilled over into the next.
  • Solana developers, on the other hand, revealed insights into how they expect to prevent future network instability, bolstering the newly announced beta release branch v1.10.

Solana engineers have devised a complex approach to improve the network’s stability after the Solana mainnet beta cluster experienced a seven-hour outage two days ago due to stalled consensus. According to a Tuesday blog, the outage, which began about 20:30 UTC on Saturday and lasted until 03:30 UTC on Sunday, was triggered by a massive influx of inbound transactions (6 million per second) that overwhelmed the network, exceeding the 100Gbps of traffic at individual nodes.

What Actually Happened

The developers refuted claims of a denial of service (DoS) attack, claiming that evidence indicates bots tried to pragmatically win a new NFT being coined using the popular candy machine program, causing the network to be overloaded. According to ZyCrypto, a similar network disruption occurred on Ethereum last weekend when many buyers attempted to mint Otherdeeds NFTs in the newly established BAYC Otherside metaverse.

Validators running out of memory and crashing, according to Solana developers, is the particular reason why consensus stalled. The blog went on to say that the main cause of the excessive memory use was insufficient votes landing to finalize older blocks, prohibiting abandoned fork cleanup. The downtime led SOL’s stock to drop over 13% to $82, however it has since recovered to $85.73 as of this writing.

Solana developers, on the other hand, revealed insights into how they expect to prevent future network instability, bolstering the newly announced beta release branch v1.10. Developers are now working on a more interoperable protocol based on QUIC, a Google-developed protocol, to replace the old UDP-based system, which is prone to abuse. There will be more choices available to adjust and improve data input while making transactions more effective, the developers claim.

What Has Been Done So Far?

They’re also developing a more sophisticated stake-weighted Quality of Service (QoS) that would prioritize users with higher staked value, terminating the present practice of accepting transactions on a first-come, first-served basis without regard for staked value.

Fee prioritization will also be available in Solana, starting with the v1.11 release. Unlike Ethereum costs, which are applied to the entire block, Solana’s charge is applied to a single state. As a result, following transactions that pay a greater fee but don’t fit within the current block will be spilled over into the next. According to its own status reporting, the latest outage on the Solana network is the 7th this year, with the single DDOS attack detected in September 2021.
