Mempool Policy Changes
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
- Transactions with version number set to 3 are now treated as standard on all networks (#29496),
|
||
|
|
subject to Opt-in Topologically Restricted Until Confirmation (TRUC) Transactions policy as
|
||
|
|
described in [BIP 431](https://github.com/bitcoin/bips/blob/master/bip-0431.mediawiki). The
|
||
|
|
policy includes limits on spending unconfirmed outputs (#28948), eviction of a previous descendant
|
||
|
|
if a more incentive-compatible one is submitted (#29306), and a maximum transaction size of 10,000vB
|
||
|
|
(#29873). These restrictions simplify the assessment of incentive compatibility of accepting or
|
||
|
|
replacing TRUC transactions, thus ensuring any replacements are more profitable for the node and
|
||
|
|
making fee-bumping more reliable.
