TheSolana community confronted its seventh outage on April 30, leading to a downtime of over seven hours. The developer workforce has come out with an outage report together with three key mitigation steps to make the community extra secure.
The community outage on Solana was brought on by a major surge within the variety of transactions as a consequence of nonfungible token (NFT) minting bots. The bots used Sweet Machine, a well-liked software utilized by Solana NFT tasks to launch collections.
The transaction quantity reached 6 million per second, overflowing particular person nodes with 100 Gbps information. Because of this, validators ran out of information reminiscence, resulting in a lack of consensus amongst them.
The builders dominated out distributed denial of service (DDoS) assaults and blamed NFT minting bots for the congestion. The community got here on-line at 03:30 UTC on Sunday, Might 1.
The official report highlighted three key mitigation steps which can be in work to make the Solana community extra resilient towards such congestion points. The primary main step is to maneuver from its present information switch protocol known as consumer datagram protocol (UDP) to Google-developed fast UDP web connection (QUIC). QUIC provides quick asynchronous communication like UDP, however with periods and move management like transmission management protocol.
The second key step is the mixing of stake-weighted transaction processing, as an alternative of its present first-come-first-serve foundation. The builders claimed a stake-weighted transaction processing together with QUIC can be extra strong.
The third mitigation step is to introduce “Payment-based execution precedence,” the place customers would have the choice so as to add an extra price on prime of the bottom price. The price prioritization is ready for the v1.11 launch.

Other than the Solana community outage, an excellent larger controversy was the beta cluster restart directions, reportedly issued by validator operators. The mentioned directions requested validators to dam NFT minting bots manually on the L1 layer.

Nonetheless, Solana’s head of communication, Austin Federa, mentioned that almost all of validators stored their distance from censoring and a brand new replace is being launched on the Sweet Machine with further anti-bot options.
That is factually inaccurate – for starters these directions weren’t issued by Solana Basis.
Second, only a few validators have adopted this.
Third, @metaplex is deploying an replace to Sweet Machine with further anti-botting.
