The core part of this PR that we need to adopt is to move the code and nonce change hook invocations to occur at tx finalization, instead of when the selfdestruct opcode is called. Additionally: * remove `SelfDestruct6780` now that it is essentially the same as `SelfDestruct` just gated by `is new contract` * don't duplicate `BalanceIncreaseSelfdestruct` (transfer to recipient of selfdestruct) in the hooked statedb and in the opcode handler for the selfdestruct opcode. * balance is burned immediately when the beneficiary of the selfdestruct is the sender, and the contract was created in the same transaction. Previously we emit two balance increases to the recipient (see above point), and a balance decrease from the sender. --------- Co-authored-by: Sina Mahmoodi <itz.s1na@gmail.com> Co-authored-by: Gary Rong <garyrong0905@gmail.com> Co-authored-by: lightclient <lightclient@protonmail.com>
