# '''Nonintentional malleability becomes impossible'''. Since signature data is no longer part of the transaction hash, changes to how the transaction was signed are no longer relevant to transaction identification. As a solution of transaction malleability, this is superior to the canonical signature approach ([https://github.com/bitcoin/bips/edit/master/bip-0062.mediawiki BIP62]): # '''Nonintentional malleability becomes impossible'''.

Currently there is only one nLockTime field in a transaction and all inputs must share the same value. [https://github.com/bitcoin/bips/edit/master/bip-0068.mediawiki BIP68] enables per-input relative-lock-time using the nSequence field, however, with a limited lock-time period and resolution.

With a soft fork, it is possible to introduce a separate witness structure to allow per-input lock-time and relative-lock-time, and a new script system that could sign and manipulate the new data (like [https://github.com/bitcoin/bips/edit/master/bip-0065.mediawiki BIP65] and [https://github.com/bitcoin/bips/edit/master/bip-0112.mediawiki BIP112]).
