Closes #473 .
This PR checks that the value stored in
GLOBAL_METADATA_TRIE_DARA_SIZE
after hashing the initial state trie is correct. Given that the initial trie is hashed and checked against the actual input hash, and that the final hash is constructed based on the initial trie, this should be enough to ensure soundness.Note that when "guessing" the initial state trie, we do not store the storage values in the trie anymore: the value is added (and the pointer overwritten) anyway in
mpt_set_payload
.
