Is &#xA;there anything specific 2 years gives us over, say, 6 months?&#xA;&#xA;Ross&#xA;&#xA;On 22/06/2015 20:23, Peter Todd wrote:&#xA;&gt; On Mon, Jun 22, 2015 at 02:18:19PM -0400, Gavin Andresen wrote:&#xA;&gt;&gt; I promised to write a BIP after I&#39;d implemented&#xA;&gt;&gt; increase-the-maximum-block-size code, so here it is.

An important part of that&#xA;&gt; testing is load testing.&#xA;&gt;&#xA;&gt; As of writing the BIP above has no mention of what switchover rules will&#xA;&gt; be used for testnet; code floating around has August 1st 2015 as that&#xA;&gt; date. I propose we use August 1st 2013.&#xA;&gt;&#xA;&gt; This switch over date should be set in the _past_ to allow for the&#xA;&gt; creation (via reorg) of a realistic full-load blockchain on testnet to&#xA;&gt; fully test the real-world behavior of the entire infrastructure&#xA;&gt; ecosystem, including questions like the scalability of block explorers,&#xA;&gt; SPV wallets, feasibility of initial syncronization, scalability of the&#xA;&gt; UTXO set, etc. While this is of course inconvenient - 2 years of 8MB&#xA;&gt; blocks is 840GB worth of data - the Bitcoin ecosystem can-not afford to&#xA;&gt; make a change like this blindly.&#xA;&gt;&#xA;&gt; I&#39;m sure with a $3.5 billion market cap at stake we can scrape together&#xA;&gt; the resources to voluntarily run a few hundred full-load full-nodes for&#xA;&gt; testing a change with the potential to destroy that market cap.&#xA;&gt;&#xA;&gt;&#xA;&gt;&#xA;&gt; _______________________________________________&#xA;&gt; bitcoin-dev mailing list&#xA;&gt; bitcoin-dev at lists.linuxfoundation.org&#xA;&gt; https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev&#xA;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150623/7a41e361/attachment.html&gt;</html></oembed>
