Ethereum's Major Dencun Upgrade Hits Snag on Testnet, Delaying Rollout of Key Expansion
-
Ethereum's Dencun upgrade went live on the Goerli testnet but failed to finalize as expected due to issues like low participation and validators not upgrading software.
-
Dencun is part of a 3-phase approach to transition Ethereum to a new, less costly data storage method called "proto-danksharding" to add capacity and reduce layer-2 costs.
-
The next phase will happen in the coming weeks with an upgrade to the Sepolia testnet, followed by the Holesky testnet.
-
Dencun is the biggest Ethereum upgrade since last March's Shapella upgrade, which enabled staked ether withdrawals.
-
Shapella marked the second step in Ethereum's transition from proof-of-work to proof-of-stake after last year's Merge.
