getblockfrompeer (blockchain command)

Bitcoin Core 25.0 RPC

getblockfrompeer "blockhash" peer_id

Attempt to fetch block from a given peer.

We must have the header for this block, e.g. using submitheader.

Subsequent calls for the same block and a new peer will cause the response from the previous peer to be ignored.

Peers generally ignore requests for a stale block that they never fully verified, or one that is more than a month old.

When a peer does not respond with a block, we will disconnect.

Note: The block could be re-pruned as soon as it is received.

Returns an empty JSON object if the request was successfully scheduled.


1. blockhash    (string, required) The block hash to try to fetch
2. peer_id      (numeric, required) The peer to fetch it from (see getpeerinfo for peer IDs)


{}    (empty JSON object)
