Anyway the stuff Mike is saying about being able to detect upgrades is incorrect - detecting an upgrade is *easier* with a soft-fork, just look at the block header nVersion numbers and warn the user if they increase beyond what you know is valid. Bitcoin Core implements this IIRC, and bitcoinj should. Someone with more time should write all this up for the bitcoin.org developer docs BTW... There's extensive discussions on #bitcoin-dev and others about all of this. --=20 'peter'[:-1]@petertodd.org 000000000000000012367d385ad11358a4a1eee86cf8ebe06a76add36dfb4622 --82I3+IH0IqGh5yIs Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQGrBAEBCACVBQJUL0GUXhSAAAAAABUAQGJsb2NraGFzaEBiaXRjb2luLm9yZzAw MDAwMDAwMDAwMDAwMDAxMjM2N2QzODVhZDExMzU4YTRhMWVlZTg2Y2Y4ZWJlMDZh NzZhZGQzNmRmYjQ2MjIvFIAAAAAAFQARcGthLWFkZHJlc3NAZ251cGcub3JncGV0 ZUBwZXRlcnRvZC5vcmcACgkQJIFAPaXwkfvCHQf/UlXeuuLzFhUUwqupzYscenT1 XiKXYYBMPeXu9QcRU0QrD08834e4yhfQ/volT/HhIT+W1HARJyHKhyQv3Fsx7Nml 5REZGK+MDo3s6q88wN1y9i13pppJq/c1TIQovu2m6mwElk1l9PAkW4x40uHFfOEf D+Mw2ZFS3A6EDj4aoZMXg5goXbVPXQe7TqZGvDWxHf1MgGOnCEy4kmTylIWIRJvC fbFvdmPEr7sLN9fdkG0ebwtyPtqBS5ZwCr5ui0GDAMGEh6ZpkE759VS4/JbP9y5o /ACL0XKOOZKQ5BvmMRldGO++IXlRu3qxdXfRSJ9FhA/ojdQ7i9CA/FxJEjX9Bw== =Wk+w -----END PGP SIGNATURE----- --82I3+IH0IqGh5yIs--
