NOTE Some debug namespace APIs are unsafe/unappropriate to be opened to public. We recommend you to provide the debug namespace APIs to authorized users only. However, if you want to maintain a public EN and provide debug namespace APIs to the public, we strongly recommend you to set the rpc.unsafe-debug.disable flag which will disable APIs that are unsafe/unappropriate to be opened to the public and enable only a subset of the debug namespace APIs. The enabled APIs are as follows:
APIs, however with limited functionality (only are allowed)
debug_dumpBlock, debug_dumpStateTrie, debug_getBlockRlp, debug_getModifiedAccountsByHash, debug_getModifiedAccountsByNumber, debug_getBadBlocks, debug_getModifiedStorageNodesByNumber
debug_metrics
Similar to , standardTraceBadBlockToFile accepts a bad block hash and will replay the bad block. It returns a list of file names containing tracing result. Note that the files will be stored in the machine that serves this API.
Console
debug.standardTraceBadBlockToFile(hash, [options])
RPC
{"method": "debug_standardTraceBadBlockToFile", "params": [hash, {}]}
Parameters
hash
32-byte DATA
블록의 해시입니다.
options
object
Return Value
JSON array
파일명의 목록입니다. 각 파일은 트랜잭션 추적 결과를 나타냅니다. 파일명 형식은 block_{first 4 bytes of the block hash}-{transaction index}-{first 4 bytes of the transaction hash}-{random string}입니다.
Example
Console
HTTP RPC
Console
debug.standardTraceBlockToFile(hash, [options])
RPC
{"method": "debug_standardTraceBlockToFile", "params": [hash, {}]}
Parameters
hash
32-byte DATA
Hash of a block.
options
object
Return Value
JSON array
A list of file names. Each represents a tracing result of a transaction. The format of a file name is block_{first 4 bytes of the block hash}-{transaction index}-{first 4 bytes of the transaction hash}-{random string}.
Example
Console
HTTP RPC
You may give trace API function a secondary optional argument, which specifies the options for this specific call. The possible options are:
disableStorage: BOOL. Setting this to true will disable storage capture (default = false).
disableMemory: BOOL. Setting this to true will disable memory capture (default = false).
disableStack: BOOL. Setting this to true will disable stack capture (default = false).
txHash: string. Setting this value will trace only the specified transaction.

Similar to , standardTraceBlockToFile accepts a block hash and will replay the block that is already present in the database. It returns a list of file names containing tracing result. Note that the files will be stored in the machine that serves this API.
