An NFT (Non-fungible token) mint program based on Solana, called Candy Machine, was hit by heavy demand traffic from bots looking to mint NFT late Saturday, causing Solana's mainnet to fall out of consensus and crash validator nodes.
The Solana Foundation said in a statement that traffic reached a record high of 4 million transactions per second around 8pm. By Sunday morning, validators started to rally and with the Solana network, nodes were slowly coming back online.
The Solana network suffered an outage that lasted for 18 hours in January, causing anger from users who were unable to withdraw their tokens and watched their portfolios plummet.
The price of Solana's SOL token fell 7.4% overnight to $83.90, according to Bloomberg data. On Sunday, it fell about 2%. Solana did his last ATH in November last year and went up to $259. However, it is currently down about 66% since ATH.
Solana Labs co-founder Anatoly Yakovenko said in a tweet after the outage that he applauded the validators on the network for working together so quickly.
"It's great to see so many new people acting together and taking ownership of the business."
In the statement made on the Metaplex Twitter account, it was stated that from now on, invalid transactions made through the Candy Machine NFT mint program will be penalized with 0.01 SOL ($ 0.89). In this way, it is aimed to prevent bot attacks.
"Today #Solana mainnet-beta went down partially due to botting on the Metaplex Candy Machine program. To combat this, we have merged and will soon deploy a botting penalty to the program as part of a broader effort to stabilize the network."
Solana wasn't the only network struggling under the weight of demand for NFTs over the weekend! Demand to buy virtual land in a metaverse game to be released by Bored Ape Yacht Club creator Yuga Labs was so high Saturday that transaction fees on the Ethereum network skyrocketed, causing the network to become clogged.
