It is trusted if (1) it is final (i.e. it can't be replaced), (2) it is not in a block that was reorged out (negative confirmation count), (3) the 'spend zero conf change' option is set, (4) it is in the mempool, and (5) all inputs are from us. > 2. When does confirmations can be -1 ( conflicted )? > What does it mean to have conflicted transaction? > Is it about Transaction Malleability? Double Spend? or both? A transaction is conflicted if a different transaction exists that spends the same inputs. A transaction gets -N confirmations if it is mined in a block, and that block is orphaned away, and a different transaction is mined in the new block so that the transaction becomes a double spend. _______________________________________________ bitcoin-dev mailing list firstname.lastname@example.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
