rjl493456442	a7f9523ae1	all: implement state history v2 (#30107) ... This pull request delivers the new version of the state history, where the raw storage key is used instead of the hash. Before the cancun fork, it's supported by protocol to destruct a specific account and therefore, all the storage slot owned by it should be wiped in the same transition. Technically, storage wiping should be performed through storage iteration, and only the storage key hash will be available for traversal if the state snapshot is not available. Therefore, the storage key hash is chosen as the identifier in the old version state history. Fortunately, account self-destruction has been deprecated by the protocol since the Cancun fork, and there are no empty accounts eligible for deletion under EIP-158. Therefore, we can conclude that no storage wiping should occur after the Cancun fork. In this case, it makes no sense to keep using hash. Besides, another big reason for making this change is the current format state history is unusable if verkle is activated. Verkle tree has a different key derivation scheme (merkle uses keccak256), the preimage of key hash must be provided in order to make verkle rollback functional. This pull request is a prerequisite for landing verkle. Additionally, the raw storage key is more human-friendly for those who want to manually check the history, even though Solidity already performs some hashing to derive the storage location. --- This pull request doesn't bump the database version, as I believe the database should still be compatible if users degrade from the new geth version to old one, the only side effect is the persistent new version state history will be unusable. --------- Co-authored-by: Zsolt Felfoldi <zsfelfoldi@gmail.com>	1 month ago

rjl493456442	6490d9897a	cmd, triedb: implement history inspection (#29267) ... This pull request introduces a database tool for inspecting the state history. It can be used for either account history or storage slot history, within a specific block range. The state output format can be chosen either with - the "rlp-encoded" values (those inserted into the merkle trie) - the "rlp-decoded" value (the raw state value) The latter one needs --raw flag.	11 months ago
