# standard transaction

URL: https://blockspace.wiki/glossary/standard-transaction/

A transaction Bitcoin Core's policy will relay, as opposed to one that is merely valid. One limit: a standard transaction weighs at most 400,000 WU (about 100,000 vB); larger ones are non-standard: default nodes will not relay them, but one can still reach a block by arrangement with a miner, like the 3,969,429-byte inscription in block 873,893.
