I think we might want multiple sets of keys: 0. No reorgs 1. Periodic reorgs of small to moderate depth for ongoing testing without excessive disruption (e.g. the every 8 hours proposal). I think this probably ought to be the default-default `-signet` in Bitcoin Core and other nodes. 2. Either frequent reorgs (e.g. every block) or a webapp that generates reorgs on demand to further reduce testing delays. If we can only have two, I'd suggest dropping 0. I think it's already the case that too few people test their software with reorgs. -Dave --hlqwu4mybssxthze Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEgxUkqkMp0LnoXjCr2dtBqWwiadMFAmE7uUUACgkQ2dtBqWwi adOXmhAAk1GlkLdd1pcvdzIO+JSBGJbSthbFXjsicz613smImFbF1tj+lLhAVQAi JKN8hQFtDd6QpZyVa2dn3+W9YE+TeKNuFTclT/SwOMBP+mEqY8k/Sl68fd00y6v7 sIj7KKkfVtpj+zDXC32VLjZWuH/6MIuwdLtV1WiU9VLu6ypiIShHzMGrH9kmmKeh mlZYeDs5VRytATGXzqUxUkM+0wn7x+Zk8S286ogeVzqe1OyKdnuyMH2eSzFPQiu2 1uoUntPaiRU9zt51GzwP2xcDJqR2u6k8Suv7G0bWVw5+fmeyKdUD6PksE7f7qZ5O VM+LCWXtWk84f6kjRR/hE9/uV5h1vnRt30W4z5jUnAiNNKGAY0BUb8lTC0M0IXaK ZSqMMEyC3994TWFs3e4dfbRyoiqwIkO9tPxe/oTvPCkt73mFyc+UdgRKJklK5WW2 29oa0vemu5QE7+mwNJZ/0/YmCHEwmxrE9kBPfFSortj5fIpEWFxZu3aE0TPeXvUl Aswps7ZC6kwSymKoMd05vvfKwH1gxNeAFBDDiDEup90YcB/DtlNWQCaOUVQYHh1X CYbK/QoE79dDviJ2E/XqdLKCjixZv55x8jGGyEezdovRl6qt/AVAlaL0xZ2FiRmK guSWYZbkw5IyB5mrigDEOAa+vbnPYqjZVoAA/VMz1+/QrM36Qxg= =0XVj -----END PGP SIGNATURE----- --hlqwu4mybssxthze--
