Jorge,

I applaud your efforts and objectives WRT libconsensus independence. But
as you know I differ with you on this point:

> Once we have libconsensus Bitcoin Core it's just another
> implementation

I do not consider Bitcoin Core just another implementation as long as
libconsensus is built directly out of the bitcoind repository. It's a
finer point, but an important one. Eric makes this point emphatically as
well:

>> But the consensus code should NOT be subject to the same commit
policies...and we should make an effort to separate the two clearly.

As you have implied, it's not likely to happen in the Bitcoin Core repo.
Taking a dependency on Bitcoin Core is a metaphorical deal with the
devil from our perspective. So my question is, how do you expect other
implementations to transition off of that repository (and commit
policies)? Or do you expect the dependency to be perpetual?

In our discussion leading up to libbitcoin building libbitcoin-consensus
we disagreed on whether intentional hard forks would (or even could)
happen. I think that issue is now settled. So my question remains how do
stakeholders (users/miners) maintain consensus when it's their
individual intent (the first objective of libconsensus), and diverge
when intended (which a direct dependency on libconsensus makes harder)?
IMO it's unreasonable to operate as if this won't happen, given that it has.

There are a very small number of implementations that rely on consensus
(fewer that aren't also forks of Bitcoin Core). I think it's time we
discuss how to work together to achieve our mutual goal. I assume you
have been in contact with all of us. If you would like to facilitate
this I'd be happy to join in an offline discussion.
