While I think this idea isn't bad in and of itself, there is an assumption being made that the community would come to consensus regarding a future soft fork. This, IMO, is a dangerous assumption. Failure would potentially leave the network at a hard fork well past any current proposal. It would also potentially lead to miners becoming hostile players and making political demands. ("Soft fork down to X MB or I'll shut down 15% of the network hashrate and work to shut down more elsewhere.") I'd hope we can all agree that such a scenario would be terrible. I do agree that the idea of giving everybody plenty of time to plan is critical. (Telecom providers need months, if not years, to plan for even simple upgrades, which often are not as simple as they look on paper.) I just think this proposal, while well-meaning, comes across as a bit of a trojan horse as-is. I can't get behind it, although it could potentially be molded into something else that's interesting, e.g., Johnson Lau's Spoonnet. Fork-to-minimum, while introducing its own potential problems, would put much less pressure on full nodes, and on the ecosphere as a whole if the max needed to be soft forked down. (I'd also like to see SegWit go live so that we can get an idea of how much pressure there really is on the network, thereby giving us a better idea of how high we can go. I still think we're flying a bit blind in that regard.) --=20 --- Douglas Roark Cryptocurrency, network security, travel, and art. https://onename.com/droark joroark@vt.edu PGP key ID: 26623924 --PSGnJe3T1f79f5CdHmkel4Ulgoihg6hFr-- --cb5S5efUAoUpFSMia2sFt7PVBcW7gMoT1 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQIcBAEBCgAGBQJY2qJ6AAoJEEOBHRomYjkkXZcP/38qrnjqLf2xYpDaO/SMTnbB wA+0pbUATddiQqJ9i9kfGfc/vU5fSsqns/H+4RemDW/lCJ92xdyiWPJ1SXsx1OQh mlkdIiLfWzn7vg1yVxnauST8cNNh3eL4x4iv+T/+jvhI0gIpIJzWmB+wqHc0jtUf /+tE7abA5qVkw0JPSaPf98fQvYlcts+13oW1gfjvsPvNKGwWNeVuSrBp0CCFzp4C c46epMf/OuHhNef60ahP700qnwQGI+wUcZZql5uD6sySHUy5r21bGHd3krVz5mw+ 1m5qFKM3Wz5raklgt8bR8dH6y1UxfbUfsCXDYY9uaneegSzd9vcE84yPrGcOcmQ+ 5GrjKwDi1AHHJhY/KzNwI7Cf7xek4Aex6+56xTuC2oOIw005uH3tilZHxnKYcYYD 9dn1pJWPyjw5/6CRupbC9fO60/bB1FY7ltCdzh1EuetAP+tRcqAFABsxVMeFBBew Siud+tqFzTrBEX9Wtkq+dqym9L0rPATn0+CgHQOSw3+reKGFEABgHoWV9aOve5y7 ijOVzYTYeiZr4wdh3wVtLCKbc62+EZgJ0idZrYlh1Mp8k+y30Axw2X8qDXD/SKZJ O/h3z3SQK6Q31Fwd5uemrNd7LCHjHa4bH6ryBivHouExn0gn7/Vwr6tTI+INhtd/ kb2emzGb7DpI5clI5DIe =vgTH -----END PGP SIGNATURE----- --cb5S5efUAoUpFSMia2sFt7PVBcW7gMoT1--
