In preparation for the “open pledge withdrawal”, Ethereum launched Shanghai to upgrade the “shadow fork”

An ethereum developer said the Shanghai upgrade’s “Shadow Fork” (Shadow Fork) has gone live. A shadow fork is a stress-testing environment that allows ethereum developers to practice functions such as running nodes, deploying smart contracts, and testing infrastructure in order to evaluate network upgrades before they occur.

According to Marius Van Der Wijden, a software developer at the Ethereum Foundation, while there were some outages on Ethereum nodes using the Geth client within a few hours of the fork, the issues have now been fixed.
The development team has previously finalized that the “Shanghai Upgrade” hard fork will be carried out in March this year. At that time, the withdrawal function of the pledged Ethereum of the beacon chain will also be launched to allow Ethereum validators to withdraw the assets pledged on the chain.

To be sure, Ethereum will conduct a series of test forks to copy data from the main network to the test environment. During this latest shadow fork, developers focused on creating a test environment for staked ether withdrawals and making improvements to reduce gas costs.

On the other hand, Shanghai’s upgraded public testnet will also go live in the next few days.
