Shanghai is the next planned network upgrade on Ethereum Mainnet
which is expected to activate *Withdrawal* of staking rewards with EIP-4895.
This could be extremely beneficial for the on-chain validators.
Shanghai upgrade may bring significant feature upgrades to EVM with a set of proposals.
EIP-3540, also known as the EVM Object Format (EOF) proposes an extensible and versioned
container format for the EVM with a once-off validation at deploy time.
There are a bunch of EIPs proposed bt team Epsilon for EVM improvement.
Shandong is the first experimental testnet deployed with a bunch of EOF EIPs by the Ethereum JS team.
Community may expect multiple iterations of this testnet to test different CFI EIPs.
EIP-4895: Beacon chain push withdrawals as operations
a system-level “operation” to support validator withdrawals that
are “pushed” from the beacon chain to the EVM.
These operations create unconditional balance increases to the specified
EIP-3540: EVM Object Format (EOF) v1
introduces an extensible and versioned container format for
the EVM with a once-off validation at deploy time. The version described
here brings the tangible benefit of code and data separation, and allows for
easy introduction of a variety of changes in the future. This change relies
on the reserved byte introduced by EIP-3541.
EIP-3860: Limit and meter initcode extends
EIP-170 by introducing a maximum size limit for initcode. Furthermore, we
charge of 2 gas for every 32-byte chunk of initcode to represent the cost of
jumpdest-analysis. Lastly, the size limit
results in the nice-to-have property that EVM code size, code offset (PC),
and jump offset fits a 16-bit value.
EIP-3670: EOF - Code Validation introduces
code validation at contract creation time for EOF formatted
(EIP-3540) contracts. Reject contracts which contain truncated PUSH-data or
undefined instructions. Legacy bytecode (code which is not EOF formatted) is
unaffected by this change.
