Why? Because most people have better things to do than try to steal a few newspapers. They probably were much more closely monitored earlier in their history…but once it became clear that despite the obvious attack vector very few people actually try to game it, vendors figured it wasn’t really that big a risk. Same thing applies to people trying to steal a piece of bubble gum at the cash register at a convenience store by double-spending.\n\n- Eric Lombrozo\n\n\u003e ------------------------------------------------------------------------------\n\u003e _______________________________________________\n\u003e Bitcoin-development mailing list\n\u003e Bitcoin-development at lists.sourceforge.net\n\u003e https://lists.sourceforge.net/lists/listinfo/bitcoin-development\n\n-------------- next part --------------\nA non-text attachment was scrubbed...\nName: signature.asc\nType: application/pgp-signature\nSize: 842 bytes\nDesc: Message signed with OpenPGP using GPGMail\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150619/82936006/attachment.sig\u003e"}
