Blockchain Inspection

debug_dumpBlock
Retrieves the state that corresponds to the block number and returns a list of accounts (including storage and code).
NOTE: This function correctly returns the state for a few latest, currently 4, block numbers. Retrieving older block state is restricted depending on the value set for the command-line option --state.block-interval (default: 128). This means that the function performs the state retrieval against only the block numbers that are multiples of state.block-interval. For example, when state.block-interval is 128, this function returns the state for the block numbers "0x0", "0x80", "0x100", "0x180", and so on. If the block number is not a multiple of state.block-interval, it returns 'missing trie node' error.

debug_getModifiedAccountsByHash
Returns all accounts that have changed between the two blocks specified by their block hashes. Changes made in endBlockHash are included, but changes made in startBlockHash are not. If endBlockHash is not given, it returns the accounts modified in the startBlockHash. A change is defined as a difference in nonce, balance, code hash, or storage hash.
