According to Golden Finance, the Ethereum Foundation stated in its official blog that during the activation of the Pectra test network, problems existing in the client's configuration changes in the Ethereum test online deposit contract configuration were exposed. Although the recovery process of the Sepolia network is relatively direct and has been fully restored, the Holesky network has experienced a large number of inactive leaks in the recovery mechanism. The Holesky network has since completed its final confirmation, but it will take about a year for the exiting validator to be completely removed from the validator cluster. While stakers can test deposits, merges, and all other Pectra features, the scale of the exit queue makes it impossible for Holesky to use to test the full validator lifecycle within a reasonable time frame. To solve this problem, a new testnet has been launched: Hoodi. It will activate the Pectra network upgrade on epoch 2048 (Wednesday, March 26, 2025 15:37:12 Beijing time). In the future, staking operators and infrastructure providers should use Hoodi for validator testing. To allow time for migration, Holesky testnet will support it until September 2025. All other Pectra features can be tested on Holesky except for the validator exit. Summary of test network and its uses: Holesky: Verifier and staking provider (expected termination date is September 30, 2025). Client developers will also use Holesky to test Gas limit increase and other protocol stress tests. Sepolia: Application and Tools Developer (expected termination date is September 30, 2026). Hoodi: Verifier and staking provider (expected termination date is September 30, 2028). Planned Sepolia alternative: expected to be launched in March 2026.
