I'll point out that I personally raised an issue with segpregated witnesses quite recently - my concern that it could make validationless mining easier and more profitable(1). Neither Pieter Wuille nor Gregory Maxwell believed my concern to be important at first in private communication. However, it was still discussed on IRC, with Pieter, Greg, and others contributing valuable input on the problem and my proposed fix. Right now I think the next step for me is to write the code to implement my fix and submit a pull-req against the segwit branch. I certainly wouldn't describe that experience as "Here's the spec, take it or leave it; We don't what what you think." 1) "Segregated witnesses and validationless mining", Peter Todd, Dec 23 2015, Bitcoin-dev mailing list, http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-December/01= 2103.html --=20 'peter'[:-1]@petertodd.org 000000000000000004aea2cfdb89c4816b7a42208dca1f3cfd66a1c9b5df4506 --KsGdsel6WgEHnImy Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQGrBAEBCACVBQJWkALIXhSAAAAAABUAQGJsb2NraGFzaEBiaXRjb2luLm9yZzAw MDAwMDAwMDAwMDAwMDAwNGFlYTJjZmRiODljNDgxNmI3YTQyMjA4ZGNhMWYzY2Zk NjZhMWM5YjVkZjQ1MDYvFIAAAAAAFQARcGthLWFkZHJlc3NAZ251cGcub3JncGV0 ZUBwZXRlcnRvZC5vcmcACgkQwIXyHOf0udz/ugf/XhEjFm4lXeyj8jSdzdExr1Pb RgZplXL4kPW7M1MEKK97JzveFkVrSgpfx7dBO2zg8921aY14f6KVc1QIiYioqJ1G lqU5WJ0xFSKI+3btVfe07lDRUXv/xaxLzJENiDa+58YJO2afDW3uSD1b1zxAfhx5 xAdQpuOYDl9JvL7LSggK9xMoqrWQo9rb+y5fLe96DF6XD+0AJuUjrOcrZq2SWzDf HCWKvddB1ywCdmlucPcv1zlzUOk/C6GS8U3QXsrf5squIPmBkxz2dDMLz1Y7Cj9D Ue9otE8pwNAZfEkz0tYChkk9i5kVTNkTGsJgRN9zachH2uMbAmXX+XTUZtAdSA== =NqC/ -----END PGP SIGNATURE----- --KsGdsel6WgEHnImy--
