Additionally, it's a technical vulnerability as well: we\n\u003e \u003e want\n\u003e \u003e getting into the ASIC manufacturing and design business to have as low\n\u003e \u003e barriers\n\u003e \u003e to entry as is feasible, and the ASICBOOST exploit significantly increases\n\u003e \u003e the\n\u003e \u003e minimum capital requirements to do so.\n\u003e \u003e\n\u003e \n\u003e Asicboost also has the problem that it isn't treating the hashing as a\n\u003e black box, and thus has impacts on what gets mined. In particular it\n\u003e creates an incentive to make blocks smaller. That's a very unwanted effect,\n\u003e and anything like it should be engineered out on principle.\n\nAgreed! There's no benefit to Bitcoin for having it - one way or the other\nminers are going to destroy ~12BTC/block worth of energy. Meanwhile it appears\nto have lead to something like a year of stupid political bullshit based on a\nsecret advantage - there's no reason to invite a repeat of this episode.\n\n-- \nhttps://petertodd.org 'peter'[:-1]@petertodd.org\n-------------- next part --------------\nA non-text attachment was scrubbed...\nName: signature.asc\nType: application/pgp-signature\nSize: 455 bytes\nDesc: Digital signature\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20170405/887d8809/attachment.sig\u003e"}
