One reason might be because&#xA;&gt; other miners with such a contract - a majority - are going to be asked&#xA;&gt; by Coinbase to reorg you out of the blockchain, but then we have a&#xA;&gt; situation where a single entity has control of the blockchain.&#xA;&gt;&#xA;&#xA;If someone did enter into contracts with miners to mine certain&#xA;transactions, and had a guarantee that the miners would not build on&#xA;previous blocks which included double spends, then they would only need&#xA;contracts with 51% of the network anyway. So it wouldn&#39;t really matter if&#xA;you were a small time miner and wanted to run full-RBF.&#xA;&#xA;&#xA;&gt; For the good of Bitcoin, and your own company, you&#39;d do well to firmly&#xA;&gt; state that under no condition will Coinbase ever enter into mining&#xA;&gt; contracts.&#xA;&gt;&#xA;&#xA;I don&#39;t personally see what good this does for bitcoin. Now you are&#xA;suggesting that we should prevent a 51% attack by using policy and&#xA;promises, rather than a technical solution. How is this any better than us&#xA;relying on existing double spend rules which are based on policy and&#xA;promises?&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150619/ad6b6736/attachment.html&gt;</html></oembed>
