What is the Ethereum Shanghai Update?

The Ethereum Shanghai update is the update scheduled to arrive soon after the first Ethereum merge deployment. As laid out by developer Tim Beiko, the Shanghai version addresses three critical issues surrounding Ethereum. It introduces changes in the EVM object format, Beacon Chain withdrawals, and L2 fee reduction.

To begin, the EVM object format will separate the code from the data. This could be extremely beneficial for the on-chain validators. Alongside the separation, EIP-3540 introduces a new contract code section that helps in tackling and resolving complex features such as Account Abstraction, control flow in EVM, and EIP-3074.

The Shanghai update also addresses the Beacon chain withdrawal delay. This aspect of the update will allow Ethereum holders to withdraw their deposited ETH, which previously wasn’t possible.

Lastly, the update introduces changes that will effectively lower the notorious gas prices of Ethereum. The changes will be made by equalizing the block sizes and increasing the CALL DATA functionality of the block.
