Ethereum Testnet Processes First ETH Staking Withdrawals
The upgrade on the Zhejiang testnet was the first of three dress rehearsals for the much anticipated Shanghai hard fork.
An Ethererum test network (testnet) successfully simulated withdrawals of staked ether (ETH) for the first time, bringing the second-biggest blockchain yet another step closer to its historic transition to a fully featured proof-of-stake network. The upgrade was triggered at epoch 1350 at 15:00 UTC and finalized at 15:13 UTC. (10:13 a.m. ET).
The testnet, known as Zhejiang, facilitated the withdrawal simulations early Tuesday after going live last week, according to an explorer website set up to track transactions on the system. The test network is designed to provide developers with a dress rehearsal of the withdrawals similar to those that will happen on the main Ethereum blockchain following its long-awaited Shanghai upgrade, expected next month.
"On the Zhejiang testnet, partial and full withdrawals as well as BLS changes are included in the execution payload," Barnabas Busa, a DevOps engineer at the Ethereum Foundation, told CoinDesk. "We have a successful fork." BLS changes allow people to change their withdrawal credentials to properly process staked ether withdrawals.
Zhejiang is the first of three testnets to run through a simulation of Shanghai. Testnets duplicate the main blockchain, and allow developers and users to test any code changes to their applications in a low-stakes environment.
The next testnet upgrade will happen sometime in the next few weeks to Sepolia, followed by Goerli.
