Holesky Ethereum testnet has regained finality after nearly two weeks of instability.

The network's disruption had stalled testing for the anticipated Pectra upgrade, delaying progress on the upcoming hard fork.

The network had been disrupted for nearly two weeks, shutting down testing for the anticipated Pectra upgrade and delaying progress on the upcoming hard fork.

However, with the testnet now operational, EthPandaOps, a group of Ethereum developers, confirmed that validators could resume Pectra testing on the environment.

The developers also recommended that solo stakers use the Ephemery testnet as an alternative environment for independent testing.

Holesky testnet

On March 10, EthPandaOps confirmed that Holesky reached finality at Epoch 119090. This milestone was achieved after more than two-thirds of the validators participated, stabilizing the network.

After several days of instability, Holesky testnet finally returned to normal on February 24.

During this period of disruption, the testnet failed to finalize during Pectra testing, an upgrade that is still in development.

The issue arose when execution clients, such as Geth, used incorrect deposit contract addresses, leading to an execution layer (EL) bug. This misconfiguration caused chain splits and destabilized the network.

An initial attempt to rectify the issue failed due to insufficient validator participation. However, with finality now restored, all test transactions on Holesky are permanent and irreversible.

EthPandaOps noted that since its recovery, Holesky has remained stable, with ongoing finalizations. Some epochs have seen lower validator participation as users transition from temporary fixes to stable setups. Despite this, the network remains functional and ready for further testing.

Meanwhile, the developers also pointed out that the exit queue is filled with slashed validators and those below the required balance, amounting to nearly one million validators. However, around 700,000 remain active, with their balances expected to rise as they continue fulfilling network duties.

Other challenges

Holesky’s recovery comes as Ethereum developers address another issue on Sepolia, another test network.

Last week, Beiko reported that a custom deposit contract problem disrupted certain execution layer clients on Sepolia, affecting transactions within blocks.

Despite these challenges, Ethereum developers remain confident that Pectra could launch as scheduled in April. The upgrade will introduce several changes to the blockchain, including a new rendering engine for efficient rendering of Web3 applications.
