The Dencun upgrade was implemented on Ethereum’s Goerli testnet, but a bug in Prysm kept the network from finalizing for nearly four hours.
The newest upgrade to the Ethereum network, codenamed “Cancun-Deneb” or “Dencun,” has gone live on the Goerli testnet for the first time, according to a Jan. 17 social media post from Ethereum developer Parithosh Jayanthi.
According to Jayanthi, a bug delayed the network’s launch for approximately four hours. But once this problem was fixed through a patch, the network came back up.
Once implemented on the mainnet, the Dencun upgrade will significantly lower the cost of transactions on Ethereum layer 2s such as Optimism, Base, Polygon zkEVM and others, developers have claimed. It will also limit self-destruct operations and allow for new bridge and staking pool features.
