Perhaps we should remove (and not maintain) this file? This script is mostly non-functional in general, as the module nodeconsensus is not available anywhere. It was presumably some form of bindings to Bitcoin Core libbitcoinconsensus library similar to bitcoinconsensus. I looked at this a year or so ago, and used a different approach that was compatible with AFL, I can lookup where the branch is if necessary.

Hmm, yeah maybe we should remove the /scripts directory:

certs.sh: only relevant for bip70, removed from bcoin a long time ago
dump.js: requires npm package heapdump, not a bcoin dependency, dumps a heap snapshot in the repo root directory, not sure what its for.
fuzz.js: see above
gen.js: needs a new keyword on line 36, otherwise works. Probably useful when the library was first started, but genesis blocks are stored in lib/protocol/networks.js now.
seeds.sh: pretty cool script to download seed nodes from bitcoin core repository. Had a bug when run on my shell (head: illegal line count -- -1 but that was fixed by changing line 13 & 14 in the script)

[braydonf]

certs.sh: True, only relevant for bip70.
dump.js: Also not sure how it was used.
fuzz.js: Yep, this could become part of fuzz testing setup if maintained.
gen.js: True, also tested the fix and it works, but as mentioned may not be necessary.
seeds.sh: I didn't have a bug when running. This may be useful, seeds will likely need to be updated.

[pinheadmz]

so...

certs.sh: remove
dump.js: remove
fuzz.js: remove? or fix the toString and remove nodeconsensus path?
gen.js: remove
seeds.sh: keep - may be only truly useful script here

...?
