Ethereum Foundation: The new testnet Hoodi will activate the Pectra network upgrade on March 26
ChainCatcher message, the Ethereum Foundation stated in its official blog that during the activation process of the Pectra testnet, issues were exposed regarding the configuration changes of the deposit contract on the Ethereum testnet in the client. Although the recovery process of the Sepolia network was relatively straightforward and has now been fully restored, the Holesky network experienced a significant amount of inactive leakage during the recovery mechanism. The Holesky network has since completed its final confirmation, but it will take about a year for the exiting validators to be completely removed from the validator set. While stakers can test deposits, merges, and all other Pectra features, the scale of the exit queue makes Holesky unsuitable for testing the complete validator lifecycle within a reasonable timeframe.To address this issue, a new testnet has been launched: Hoodi. It will activate the Pectra network upgrade at epoch 2048 (Beijing time March 26, 2025, Wednesday 15:37:12). In the future, staking operators and infrastructure providers should use Hoodi for validator testing. To allow time for migration, the Holesky testnet will be supported until September 2025. All other Pectra features can be tested on Holesky except for validator exits.Summary of testnets and their uses:Holesky: Validators and staking providers (expected termination date: September 30, 2025). Client developers will also use Holesky to test gas limit increases and other protocol stress tests.Sepolia: Application and tool developers (expected termination date: September 30, 2026).Hoodi: Validators and staking providers (expected termination date: September 30, 2028).Planned Sepolia alternative: Expected to launch in March 2026.
