In a low margin business like mining,\nthe advatange it gives is enormous - quite possibly 10x your profit margin -\nand given that barrier free access to being able to purchase ASICs is already\nan archilles heal for Bitcoin there is every reason to eliminate this legal\nvulnerability. Additionally, it's a technical vulnerability as well: we want\ngetting into the ASIC manufacturing and design business to have as low barriers\nto entry as is feasible, and the ASICBOOST exploit significantly increases the\nminimum capital requirements to do so.\n\nRemember that the whole purpose of PoW is to destroy value on a level playing\nfield. Anything that inhibits a level playing field is an exploit. While this\nisn't standard crypto - we can't fix every exploit completely - since we're\ngoing to do a technical change to partially mitigate the ASCIBOOST exploit\nthere is every reason to fully mitigate it.\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/20170405/90b81cc9/attachment-0001.sig\u003e"}
