I've been working on regrinding three vpatches that are being considered for integration into the current <a href="http://thebitcoin.foundation/v/patches/">TRB vtree</a> (keccak). <br /> 

<br />
These three vpatches, along with their signatures, are placed into this article (see below) for testing.  They have been signed with my '<a href="http://www.mod6.net/mod6-vpatch-testing/mod6-vpatch-testing.asc">mod6-vpatch-testing</a>' key. (For those who do not know, I use a secondary key for signing vpatches that are still considered "not final", "experimental", or "testing".) <br /> 

<br />
Here are the vpatches and their seals (signatures) with my 'mod6-vpatch-testing' key.  Most importantly, let it not go unsaid:  Any vpatch signed with my 'mod6-vpatch-testing' key is for <b>TESTING ONLY</b>.  You should <b>NEVER</b> use a vpatch in 'production' or 'battlefield' mode that has been signed with my vpatch testing key.  Also, as always, be sure to read <b>ALL</b> code before you put it into use!  Only you, dear reader, can be the guardian of your own safety. <br />
<br />

Below are the three vpatches, currently in testing, along with their corresponding seals.  I am also linking their historical posts to the btc-dev Mailing List.  <br />

&nbsp;&nbsp; ** New single line change by me in a conditional statement.<br />

Building a testing vtree with these new vpatches:<br />
1. You'll need a Keccak vtron, find 'starter_v_2.tar.gz' <a href="http://ossasepia.com/2019/11/10/v-tree-and-v-starter-v2/">here</a>, by <a href="http://wot.deedbot.org/E72DCCB73A5E06694C5CD781D5196EE6390F999E.html">diana_coman</a>.<br />
2. You'll need a full copy of the current TRB vtree (keccak); <a href="http://thebitcoin.foundation/v/patches/">vpatches</a> and their corresponding <a href="http://thebitcoin.foundation/v/seals/">seals</a>.<br />
3. Place these in your patches and .seals directories respectively.
4. You'll need to place the vpatches for testing (phexdigit_fix, excise_hash_truncation, whogaveblox) in your 'patches' directory.<br />
5. You'll need to place the their corresponding seals (signed with my '<a href="http://www.mod6.net/mod6-vpatch-testing/mod6-vpatch-testing.asc">mod6-vpatch-testing' key</a>) into your '.seals' directory.<br />
6. You'll need to get my <a href="http://www.mod6.net/mod6.asc">main key</a> and place it in your '.wot' directory.<br />
7. You'll need to get my <a href="http://www.mod6.net/mod6-vpatch-testing/mod6-vpatch-testing.asc">mod6-vpatch-testing key</a> and place it in your '.wot' directory.<br />
8. Now you should have 'mod6_whogaveblox.vpatch' as a single leaf:<br />
<pre>
<code>
mod6@gentoo ~ $ vk.pl l
Leaf: mod6_whogaveblox.vpatch (mod6-vpatch-testing)
</code>
</pre>
<br />
9. You should have a flow that looks like this:<br />

As far as my own testing, I have been able to place these vpatches, along with their seals into V, and press all the way up through the single leaf, 'mod6_whogaveblox.vpatch'.  After successful press, I was able to successfully compile TRB.  I haven't completed any further testing as of yet.  Testing is on-going, currently.    I anticipate about 7 to 10 days of further testing before completion.<br /> 

That's all for now -- upon successful testing, will be issuing final signatures with my <a href="http://www.mod6.net/mod6.asc">main key</a> for these vpatches (see above) in a follow up article.<br  />
