Zero-conf transactions also aren&#39;t that tied&#xA;to the Bitcoin valuation.&#xA;&#xA;Multisignature notaries need to convince people to select them. They want&#xA;to know that even with collateral, their funds won&#39;t be temporarily locked&#xA;up and unspendable for days at a time.&#xA;&#xA;What services would miners provide here, do you think?&#xA;&#xA;&gt; Well, sure. It&#39;s the same model governments use and is why being a money&#xA;transmitter in the USA is so difficult: you need to put up large sums of&#xA;money as collateral and have your fingerprints taken 48 times. Then you can&#xA;start advertising to get customers!&#xA;&#xA;Obviously you need to have collateral to provide collateral. Can&#39;t make&#xA;cryptographic verifiable guarantees if you don&#39;t have the resources to back&#xA;them.&#xA;&#xA;&gt; The reason mining is such a nice model is it doesn&#39;t have these sorts of&#xA;requirements.&#xA;&#xA;And also can&#39;t make these assurances. Any minority miner can be overrun.&#xA;&#xA;&gt;&gt; As notaries can be small operations ..... [snip] ...... (almost every&#xA;large organization in the world have some unallocated funds somewhere).&#xA;&gt;&#xA;&gt; Which is it? Are notaries small operations or large operations?&#xA;&#xA;The operation itself is small. A few people maintaining a few servers.&#xA;&#xA;The collateral needed depends on how many and how large simultaneous&#xA;transactions they want to provide assurances for, so they can chose to be a&#xA;small player for one niche market or large and global if they have the&#xA;funds for it.&#xA;&#xA;&gt; I think exploring new consensus models with semi-trusted notaries is&#xA;interesting, but it&#39;s not Bitcoin.&#xA;&#xA;Methods for decentralized consensus that aren&#39;t PoW also aren&#39;t Bitcoin.&#xA;&#xA;&gt; Please don&#39;t try and apply this logic in the real world :( Rephrased:&#xA;&gt;&#xA;&gt; &#34;That&#39;s a nice house. I noticed it&#39;s made of wood. I&#39;m going to start&#xA;fires until it burns down, because there is no guarantee your house won&#39;t&#xA;burn down in future and it&#39;s important you understand that wooden houses&#xA;aren&#39;t safe. Really I&#39;m just doing you a favour.&#34;&#xA;&#xA;Actually that IS often a bad idea. But fortunately the risk and threat is&#xA;low, and mitigation is well understood.&#xA;&#xA;&gt; I&#39;m really not a fan of Peter&#39;s approach, which is &#34;hey let&#39;s try and&#xA;cause as many problems as possible to try and prove a point, without having&#xA;created any solutions&#34;. Replace-by-fee-scorched-earth doesn&#39;t work and&#xA;isn&#39;t a solution. Miners can easily cut payment fraudsters in on the stolen&#xA;money, and as they&#39;d need to distribute custom double-spending wallets to&#xA;make the scheme work it&#39;d be very easy to do.&#xA;&#xA;Security analysis requires having the mindset of an attacker. Sometimes&#xA;that reveals suboptimal choices. Then you want them changed to more stable&#xA;choices such that once the incentives change, the risk already is gone.&#xA;Minimization of damage, simply put.&#xA;&#xA;&gt;&gt; Your also ssume people will expect the Bitcoin network to keep zero-conf&#xA;safe forever and that Bitcoin valuation is tied to that. Given the options&#xA;available and current state of things, I&#39;m assuming that&#39;s wrong.&#xA;&gt;&#xA;&gt; Why? You think ability to make payments in a few seconds is some&#xA;irrelevant curiousity?&#xA;&#xA;No. But you can&#39;t be certain it is secure without having a solid reliable&#xA;mechanism to provide such a guarantee.&#xA;&#xA;You want zero-conf to stay safe without involvement of servers? Then&#xA;please, try to find a way to secure it. Right now you&#39;re assuming it can&#xA;remain safe based on circumstances which can change and assumptions about&#xA;market participant&#39;s valuations that likely aren&#39;t true.&#xA;&#xA;&gt; Let&#39;s put it this way. If BitPay&#39;s business model evaporates tomorrow,&#xA;along with all the merchants they support, do you think that&#39;d have any&#xA;effect on Bitcoin&#39;s value? If not, why not?&#xA;&#xA;It would. They&#39;d tank. But you&#39;re assuming too much about the basis for&#xA;valuation.&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150212/437c2f0a/attachment.html&gt;</html></oembed>
