By "impact" I am referring to the impact on transaction size and thus blockchain space and fees, not UTXO size as stored by nodes themselves. Specifically take the size of the txout and txin and compare the version using P2SH to the equivalent version not using it to get my numbers. Anyway, given how much uncompressed keys are still used obviously fee pressure isn't even close to getting people to create efficient transactions. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEcBAEBCAAGBQJR4v6QAAoJEEWCsU4mNhiP/ToH/1zwzkG0v8OphBaglzhF/dha QgRXy3CGQqs43w1hEsfPNaZUyKIZz2gmGtJV2PUh5FavhWY9IUuMCVLvPJ18KZkc eCLtAWSlUkjemXz6S52RPXW3vmKTJzZK4ZBZP0JiRYfhBQWbUlArLh+mQw9RcWng 9fdS/Xw4QYFfnN46NMlHdHyqGn4Mu8VgsozeUlxWXBGorf2+IFbMxR1BRi33CluH 3r6AIRHXPSqgHf6qnHgWqKh/WXMxuG8lLyLa00Rj+ByNcNQCwLV/+9AzSJYNA5Ol nnGdkbVDtLjmDS4KjwuSXGP8jh/uRrHLubcgk6UEm27K2/yJxARBfECo78aBLsg= =Nx+9 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
