I,Degen - Deep Dive

Solana Blockchain’s 11th outage, 7th of 2022.- Solana Incident Report

What: May, 1st - 4M transactions per second, initiated by NFT minting bots, took down Solana blockchain by preventing nodes from reaching consensus. The bots were targeting the Metaplex Candy Machine.

What is Metaplex?
Allows users to mint and sell NFTs.

On securing the network, from their site:

Security
Prevent bots from interfering with NFT sales with decentralized architecture, Certified Collections, and CAPTCHAS.

Metaplex poses a solution charge a tax/fee on failed TXs.

Based on a Twitter poll on the same thread with the solution, 5k votes total. With 75% no, and 25% yes.

The speculation was that:
“Eth & AVAX maxi’s voting no”
“Bots voting no”

However, the proposed solution looks like an anti-pattern!

There is a chance that a real user could hit one of these cases, especially in # 2 (Trying to mint when there are no items left in the candy machine). But we think these will not be frequent.
This is not a fool proof fix, and it will not completely stop congestion but we belive it has a substantial enough impact to attempt it.

How does Solana Consensus Work?
