Replace-by-fee transactions
|

|
---------------------------
|
||||||
|
|
||||||
|
It is now possible to replace transactions in the transaction memory pool of
|
||||||
|
Bitcoin Core 0.12 nodes. Bitcoin Core will only replace transactions which
|
||||||
|
have any of their inputs' `nSequence` number set to less than `0xffffffff - 1`.
|
||||||
|
Moreover, a replacement transaction may only be accepted when it pays
|
||||||
|
sufficient fee, as described in [BIP 125]
|
||||||
|
(https://github.com/bitcoin/bips/blob/master/bip-0125.mediawiki).
