The Solana (CRYPTO: SOL) network was forced to stop block production for four hours on Wednesday.

What Happened: Validators reported the issue around 1 p.m. ET on the Solana Status Twitter page.

The bug was related to the “durable nonce” feature of the blockchain, which caused the network to consider some blocks invalid, and as a result consensus cannot be reached.

Around 5 p.m. ET, Solana validators brought the network back online by way of a restart.

Solana is considered an Ethereum (CRYPTO: ETH) killer because of its high-speed transactions with lower transaction fees. However, multiple outages over the last few months have made some industry proponents question the network’s reliability.
