Estimate Priority

The estimatepriority RPC estimates the priority (coin age) that a transaction needs in order to be included within a certain number of blocks as a free high-priority transaction. This should not to be confused with the prioritisetransaction RPC which will remain supported for adding fee deltas to transactions.

Transaction priority is relative to a transaction’s byte size.

Parameter #1—how many blocks the transaction may wait before being included as a free high-priority transaction

Name Type Presence Description
Blocks number (int) Required
(exactly 1)

Result—the priority a transaction needs

Name Type Presence Description
result number (real) Required
(exactly 1)
The estimated priority the transaction should have in order to be included within the specified number of blocks. If the node doesn’t have enough information to make an estimate, the value -1 will be returned
