On June 1, the cryptocurrency blockchain Solana (SOL) stopped working for about four hours due to a bug in the software.
According to Solana project co-founder Anatoly Yakovenko, the network failure was due to a bug in the mechanism for assigning Durable nonces to transactions. Part of the validators declared the block invalid, so a consensus could not be reached and the network had to be suspended.
The developers disabled the function of adding single-use numbers and successfully restarted the blockchain. Yakovenko promised to fix the bug as soon as possible.
This is not the first time the Solana network has experienced an outage. In September 2021, the blockchain stopped functioning for nearly 18 hours due to transaction overload. On April 30, the network shut down for seven hours after the bots issuing NFTs made more than 4 million transactions and traffic speeds exceeded 100 gigabits per second.
