Any rough edges left?
neillm03:54
If you get a testnet version going and need further testing, let me know, I have plenty of testnet coins 🙂
neillm03:55
Hrm, don't know of Sparrow either, but will check it out
eynhaender03:56
Yea, I have 2 unknown errors on my list. But I will figure it out tomorrow.

We haven't run test net in v4 yet, but should be just config as in v3.
eynhaender03:57
Does the electrum (protocol) guy have a twitter account?
evoskuil03:57
Testnetv3
evoskuil03:57
Dunno

I was telling @eynhaender we need to have some stable (ship ready) configs for 'mainnet', 'testnet' and 'regtest' at some point. Can just sit as templates in the data dir IMO
evoskuil03:59
we used to have that. Gotta maintain them tho.
evoskuil03:59
The config is two forks and some different numeric values in the bitcoin section.
neillm04:00
Yeah, but it makes it really easy for new folks to get acquainted
evoskuil04:00
Also have to have it in the online documentation.

bs.cfg -> mainnet.cfg | testnet.cfg | regtest.cfg 🤔
evoskuil04:03
testnet3.cfg
neillm04:03
^Yes, that too
evoskuil04:03
They got testnet4 now, which is all horked up. We need to add that fork.
evoskuil04:04
And signet 🙄
neillm04:05
It's almost like we want to have configs for supported bitcoin networks 😛
evoskuil04:05
Also litecoin and its various test nets.
evoskuil04:05
Tho we haven't kept up with its forks.
neillm04:06
I like Litecoin personally, but libbitcoin is NOT liblitecoin
evoskuil04:06
You should check the book. It's not libbtc.
neillm04:07
Ah, ok, then add supported configs?! 🤔

I didn't add the forks initially, but I've maintained them. If it's not a shit coin and doesn't deviate much, then it's easy.
evoskuil04:14
It was that work that initially came from Lucas Betschart when he was doing contract work on feathercoin.
evoskuil04:15
The work to generalize the configuration.
neillm04:15
^I recall, I was a fan of feathercoin too 😇
evoskuil04:15
So that's why we don't have to recompile to do testnet, etc.
evoskuil04:16
I'm surrounded by shitcoiners.
