None

Result

An object with data about the sync status.

Result Fields

Key	Type	Detail
`SYNC STATUS`	Boolean	If the node is synced, return `false`. Otherwise, return the syncing status in details as shown in `currentBlock`, `highestBlock` and `startingBlock`.
`currentBlock`	String	A hex code of an integer that represents the current block, same as `eth_blockNumber`. If `currentBlock` is showed, then `SYNC STATUS` will not showed.
`highestBlock`	String	A hex code of an integer that represents the estimated highest block. If `highestBlock` is showed, then `SYNC STATUS` will not showed.
`startingBlock`	String	A hex code of an integer that represents the block at which the import started. If `startingBlock` is showed, then `SYNC STATUS` will not showed.

If the node is syncing using snap-sync it will also contains the following:

Key	Type	Detail
`healedBytecodeBytes`	Boolean	A hex code of an integer that represents the number of bytecodes persisted to disk.
`healedBytecodes`	String	A hex code of an integer that represents the number of bytecodes downloaded.
`healedTrienodeBytes`	String	A hex code of an integer that represents the number of state trie bytes persisted to disk.
`healedTrienodes`	String	A hex code of an integer that represents the number of state trie nodes downloaded.
`healingBytecode`	String	A hex code of an integer that represents the number of bytecodes pending.
`healingTrienodes`	String	A hex code of an integer that represents the number of state trie nodes pending.
`syncedAccountBytes`	String	A hex code of an integer that represents the number of account trie bytes persisted to disk.
`syncedAccounts`	String	A hex code of an integer that represents the number of accounts downloaded.
`syncedBytecodeBytes`	String	A hex code of an integer that represents the number of bytecode bytes downloaded.
`syncedBytecodes`	String	A hex code of an integer that represents the number of bytecodes downloaded.
`syncedStorage`	String	A hex code of an integer that represents the number of storage slots downloaded.
`syncedStorageBytes`	String	A hex code of an integer that represents the number of storage trie bytes persisted to disk.

Example

Request

curl <your-endpoint> \
    -X POST \

Return

a) The node is synced

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": false
}
