OK, adding the relevant code fragment is probably the simplest and direct
option. Done.

Yes, sorry about the link. I guess you can point to #6230 . I can<br>
rebase it if needed but I would close it again because I don&#39;t want to<=
br>
have too many things from #6382 opened at the same time (is noisy and<br>
worse for review). My plan was to not open it independently at least<br>
until after #6907 (and actually after 0.12 assuming #6907 gets in by<br>
0.12). But then I would maybe open a new one and reference the old one<br>
rather than reopening #6230 (which tends to be confusing).<br>
I&#39;m not really sure what&#39;s the best answer here...but #6382 is<br>
certainly going to need rebase and the link will be broken again.<br>
Maybe one answer is to copy some text from #6230 or the commit and add<br>
it directly to the BIP instead of referencing to that commit (which<br>
will be, at least until #6907 is merged, a moving target).<br>

&gt; maybe...<br>
&gt;<br>
&gt; Now the main change would be to put in a proper BIP number! :)<br>

&gt;&gt; I wen&#39;t through the BIP draft and left a few of comments, but =
I really<br>
&gt;&gt; like its simplicity and focus. Good work!<br>

&gt;&gt; &gt; The need for an URI for this come to mind again in the last d=

&gt;&gt; &gt;&gt; Hi!<br>
&gt;&gt; &gt;&gt; My first post here, hope I&#39;m following the right conv=
entions.<br>
&gt;&gt; &gt;&gt; I had this humble idea for a while, so I thought to go ah=
ead and<br>
&gt;&gt; &gt;&gt; propose<br>
&gt;&gt; &gt;&gt; it.<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; BIP: XX<br>
&gt;&gt; &gt;&gt; Title: URI scheme for Blockchain exploration<br>
&gt;&gt; &gt;&gt; Author: Marco Pontello<br>
&gt;&gt; &gt;&gt; Status: Draft<br>
&gt;&gt; &gt;&gt; Type: Standards Track<br>
&gt;&gt; &gt;&gt; Created: 29 August 2015<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Abstract<br>
&gt;&gt; &gt;&gt; =3D=3D=3D=3D=3D=3D=3D=3D<br>
&gt;&gt; &gt;&gt; This BIP propose a simple URI scheme for looking up block=
s,<br>
&gt;&gt; &gt;&gt; transactions,<br>
&gt;&gt; &gt;&gt; addresses on a Blockchain explorer.<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Motivation<br>
&gt;&gt; &gt;&gt; =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D<br>
&gt;&gt; &gt;&gt; The purpose of this URI scheme is to enable users to hand=
le all the<br>
&gt;&gt; &gt;&gt; requests for details about blocks, transactions, etc. wit=
h their<br>
&gt;&gt; &gt;&gt; preferred<br>
&gt;&gt; &gt;&gt; tool (being that a web service or a local application).<b=
r>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Currently a Bitcoin client usually point to an arbitrary =
blockchain<br>
&gt;&gt; &gt;&gt; explorer when the user look for the details of a transact=
ion (es.<br>
&gt;&gt; &gt;&gt; Bitcoin<br>
&gt;&gt; &gt;&gt; Wallet use BitEasy, Mycelium or Electrum use Blockchain.i=
nfo, etc.).<br>
&gt;&gt; &gt;&gt; Other times resorting to cut&amp;paste is needed.<br>
&gt;&gt; &gt;&gt; The same happens with posts and messages that reference s=
ome particular<br>
&gt;&gt; &gt;&gt; txs or blocks, if they provide links at all.<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Specification<br>
&gt;&gt; &gt;&gt; =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D<br>
&gt;&gt; &gt;&gt; The URI follow this simple form:<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; blockchain: &lt;hash/string&gt;<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Examples:<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; blockchain:00000000000000001003e880d500968d51157f210c632e=
08a652af3576600198<br>
&gt;&gt; &gt;&gt; blockchain:001949<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; blockchain:3b95a766d7a99b87188d6875c8484cb2b310b78459b781=
6d4dfc3f0f7e04281a<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Rationale<br>
&gt;&gt; &gt;&gt; =3D=3D=3D=3D=3D=3D=3D=3D=3D<br>
&gt;&gt; &gt;&gt; I thought about using some more complex scheme, or adding=
 qualifiers to<br>
&gt;&gt; &gt;&gt; distinguish blocks from txs, but in the end I think that =
keeping it<br>
&gt;&gt; &gt;&gt; simple<br>
&gt;&gt; &gt;&gt; should be practical enough. Blockchain explorers can appl=
y the same<br>
&gt;&gt; &gt;&gt; disambiguation rules they are already using to process th=
e usual search<br>
&gt;&gt; &gt;&gt; box.<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; From the point of view of a wallet developer (or other to=
ol that need<br>
&gt;&gt; &gt;&gt; to<br>
&gt;&gt; &gt;&gt; show any kind of Blockchain references), using this schem=
e mean that he<br>
&gt;&gt; &gt;&gt; can simply make it a blockchain: link and be done with it=
, without<br>
&gt;&gt; &gt;&gt; having<br>
&gt;&gt; &gt;&gt; to worry about any specific Blockchain explorer or provid=
e a means for<br>
&gt;&gt; &gt;&gt; the<br>
&gt;&gt; &gt;&gt; user to select one.<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Blockchain explorers in turn will simply offer to handle =
the<br>
&gt;&gt; &gt;&gt; blockchain:<br>
&gt;&gt; &gt;&gt; URI, the first time the user visit their website, or laun=
ch/install the<br>
&gt;&gt; &gt;&gt; application, or even set themselves if there isn&#39;t al=
ready one.<br>
&gt;&gt; &gt;&gt;<br>
&gt;&gt; &gt;&gt; Users get the convenience of using always their preferred=
 explorer,<br>
&gt;&gt; &gt;&gt; which<br>
&gt;&gt; &gt;&gt; can be especially handy on mobile devices, where juggling=
 with<br>
&gt;&gt; &gt;&gt; cut&amp;paste<br>
&gt;&gt; &gt;&gt; is far from ideal.<br>
