<p>stub: TRUC (nVersion=3) 1-parent-1-child mempool policy</p> <p><b>New page</b></p><div>&#039;&#039;&#039;TRUC&#039;&#039;&#039; (Topologically Restricted Until Confirmation) is an opt-in Bitcoin Core mempool policy for transactions that set &lt;code&gt;nVersion = 3&lt;/code&gt;. It is described in [https://github.com/bitcoin/bips/blob/master/bip-0431.mediawiki BIP 431]. An unconfirmed TRUC transaction may have at most one unconfirmed parent and one unconfirmed child. The parent is limited to 10,000 vB and the child to 1,000 vB. A TRUC parent may pay below the minimum relay feerate if a package with its child meets the node&#039;s feerate rules. The policy is not a consensus change.<br /> <br /> == See also ==<br /> <br /> * [[Ephemeral_anchor]]<br /> * [[Lightning Network]]<br /> * [[Transaction]]<br /> <br /> == External links ==<br /> <br /> * [https://github.com/bitcoin/bips/blob/master/bip-0431.mediawiki BIP 431: Topology Restrictions for Pinning]<br /> * [https://bitcoinops.org/en/topics/version-3-transaction-relay/ Bitcoin Optech: Version 3 transaction relay]<br /> <br /> [[Category:Technical]]</div>
