Ethereum’s Holesky Testnet Achieves Finality

Ethereum’s Holesky testnet reached finality on Monday, almost two weeks after the Pectra upgrade went live.

Epoch 119,090 sealed the deal at around 19:00 UTC, with over two-thirds of validators validating the network. An epoch is a period of time when a specific number of blocks is completed on the blockchain.

Finality, which locks transactions irreversibly within two epochs (about 13 minutes), had been absent since Feb. 24 due to a configuration bug in the client software, rather than the Pectra upgrade itself.

Restoration efforts over the past weeks enabled this recovery. Developers are now stabilizing nodes and pruning old states to fully revive the testnet for Pectra testing.

The Sepolia testnet, also running Pectra, achieved finality but later faced issues with empty blocks due to a flawed deposit contract. An attacker exploited this by sending zero-token transfers, an issue later resolved by client teams.

The Pectra upgrade introduces key enhancements such as gas payments in non-ETH tokens, account abstraction, and higher staking limits.
