They won't be attacking Bitcoin, they will attack merchants who accept\npayments with 0 confirmations. This attack has nothing to do with Bitcoin\nconsensus mechanism (as Bitcoin protocol doesn't provide a consensus over\nmempool contents), thus it is not an attack on Bitcoin.\n2. In the example I used, having 10% of hashpower is enough to offer 10%\nsuccess rate. Would you mind having 1 out of 10 hamburgers for free? If a\nsystem can be attacked by a tiny fraction, it is a shitty system.\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150212/a6b9081f/attachment.html\u003e"}
