 The +nSequence+ field was originally intended (but never properly implemented) to allow modification of transactions in the mempool. In that use, a transaction containing inputs with +nSequence+ value below 2^32^ (0xFFFFFFFF) indicated a transaction that was not yet "finalized." Such a transaction would be held in the mempool until it was replaced by another transaction spending the same inputs with a higher +nSequence+ value. Once a transaction was received whose inputs had an +nSequence+ value of 2^32^ it would be considered "finalized" and mined.
 
-The original meaning of +nSequence+ was never properly implemented and the value of +nSequence+ is customarily set to 2^32^ in transactions that do not utilize timelocks. For transactions with nLocktime or +CHECKLOCKTIMEVERIFY+, the +nSequence+ value must be set to less than 2^32^ for the timelock guards to have effect. Customarily, it is set to 2^32^ - 1 (0xFFFFFFFE).
