Migrate supported Bitcoin testnet network to Testnet4 or Signet

[lumtis]

Describe the Issue

Bitcoin testnet3 might become deprecated and is not optimal for Bitcoin testing (chain much faster than mainnet)

This task is about finding alternative to Bitcoin testnet3 for testnet

We might want to move to Testnet4: https://mempool.space/testnet4

Blocked by #2728

We'll be adding Signet support as 1st step to provide a stable test network.

Please prioritize this: nobody can test with Testnet3 anymore. Here's the link to claim the faucet for Testnet4.

We should definitely consider it.
It doesn't seem though btcd has completed support for testnet4: btcsuite/btcd#2187
We might need to consider forking btcd

Testnet4 might not be finalized yet, but it's performing 1000% better than Testnet3, which is now deprecated. This makes it the perfect time to add support for Testnet4.

Just so you know, someone is actively working on adding the current testnet4 to btcd now (not just that open issue that we haven't finished).

Hope to have it in within a few days.

I'd of course encourage contributing to btcd rather than forking. If you tag me in any PRs, I'll make sure to take a look at it sooner rather than later!

@ronaldoguedess we're look into migrating Bitcoin testnet in one of the coming release

Do you have an opinion about using Signet instead of Testnet4?

I knew signet a few days ago on the mempool, but I believe Testnet4 will require fewer changes and it's newer.

Testnet4 also offers some great faucet tools:

Mempool Testnet4 Faucet
CoinFaucet Testnet4

Multiple Bitcoin chain zetaclient config will be supported by #2870

Hello; there was a message on #bitcoin-signet irc about wanting some coins, but @CryptoFewka (presumably?) didn't end up hanging around long enough to get an answer:

06:12 <CryptoFewka> Hey all, we're looking at integrating Signet in to ZetaChain's
                    Testnet, and are in need of a stack of sBTC. Ideally we would receive
                    enough to also disperse it to developers using our SDK to complete
                    crosschain transactions. Does anyone have any advice on how we could
                    obtain enough sBTC to enable us to distribute a small amount
                    ourselves?

FWIW, as I understand it, Babylon set up a discord bot that acted as a faucet for their users during their testing phases, maybe you want to do something similar? Feel free to ping me here or on a new issue here if you want to nail things down without timezones being as much of an issue, maybe?

[CryptoFewka]

Hey @ajtowns, my irc client kept dropping in the background and wouldn't reconnect automatically. Tracking the issue here would be great.

We have a dependency issue which prevents us from integrating testnet4 at the moment but signet integration would be straightforward.

We absolutely would like to operate our own faucet for the tokens, if we could acquire them.

[ajtowns]

Sure, point me at an address, and I'll send some "starter capital", then once you've got a faucet setup we can either do a one-off manual funding, or set it up to receive a distribution from the coinbase funds (eg).

[CryptoFewka]

Thanks. Can some sBTC please be sent here: tb1qj06h3t9vh53n960efq477jyywaj2tkyxuk0d3c?
