The reference client might even track the miner and the non-miner&#xA;&gt; chain tip.&#xA;&gt; &#xA;&gt; Miners would refuse to build on 5MB blocks, but merchants and general users&#xA;&gt; would accept them.&#xA;&#xA;That&#39;d be an excellent way to double-spend merchants, significantly&#xA;increasing the chance that the double-spend would succeed as you only&#xA;have to get sufficient hashing power to get the lucky blocks; you don&#39;t&#xA;need enough hashing power to *also* ensure those blocks don&#39;t become the&#xA;longest chain, removing the need to sybil attack your target.&#xA;&#xA;-- &#xA;&#39;peter&#39;[:-1]@petertodd.org&#xA;000000000000000004bd67400df7577a30e6f509b6bd82633efeabe6395eb65a&#xA;-------------- next part --------------&#xA;A non-text attachment was scrubbed...&#xA;Name: signature.asc&#xA;Type: application/pgp-signature&#xA;Size: 650 bytes&#xA;Desc: Digital signature&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150508/b01ee01a/attachment.sig&gt;</html></oembed>
