Cancun opcodes

Persistent data during the transaction but not after the transaction. It is more expensive than memory but cheaper than storage.

A hash of the blob’s KZG commitment. Since blobs themselves are not stored on the execution layer, this is used to validate a blob belonging to a transaction. If the blob data is altered in any way, its hash will change as well, so the actual hash found on-chain will no longer match.

Provides the blob base fee for the current block. This opcode helps with accounting for blob data usage costs, similar to the existing opcode BASEFEE.

Gas efficient way of taking one part of memory and copying it to another.
