Kiểm tra chuỗi khối
NOTE All other debug namespace APIs EXCEPT FOR the following APIs are restricted with rpc.unsafe-debug.disable
flag:
VM Tracing APIs, however with limited functionality (only pre-defined tracers are allowed)
debug_dumpBlock, debug_dumpStateTrie, debug_getBlockRlp, debug_getModifiedAccountsByHash, debug_getModifiedAccountsByNumber, debug_getBadBlocks, debug_getModifiedStorageNodesByNumber
debug_metrics
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.

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.
