Indeed, I know of few people who are familiar with the source code
that use the wiki.
I do think that is a pity. The openness and transparency of the
protocol is essential to trusting the system (and shouldn't be limited
to those digging through the source code), and for that reason alone I
think it needs to be well-documented.
I also do agree with earlier comments, that due to the nature of the
consensus problem Bitcoin solves, it will always be the network that
dictates what the actual rules are - anything else can result in
inresolvable forks. If a "formal" specification were written, and we
would find out that the majority of nodes on the network deviate from
it in a subtle way, those nodes would be buggy in the sense that they
aren't doing what was expected, but it would be the specification that
is incorrect for not following the rules of the network. In short,
consistency is more important than correctness, and for that reason,
writing alternate implementation will always be hard and dangerous.
However, I do not think that making it hard to find information about
the details of the system is the way to go. Alternate implementations
are likely inevitable, and in the long run probably a win for the
ecosystem. If effort is put into accurately describing the rules, it
should indeed carry a strong notice about it being descriptive rather
If someone is willing to work on that, I am (and likely many people in
#bitcoin-dev are) available for any questions about the protocol and
