feat: burn rune through forcing Cenotaph

[nghuyenthevinh2000]

fixes: #3640

add a command to burn all specific runes in a wallet

Logic

1. Add Burn impl in subcommand/wallet: forcing burn through Cenotaph EdictOutput Flaw

Test

1. Add a happy case test burning_rune_works():

• send 100 rune to address B
• burn rune in address A (which contains 900 rune), confirming that balances only return 100 rune
• confirm that rune info return burned amount of 900

I think it can be fine - grained further to burn exact amount in a wallet through protocol recognized burn addresses. However, changes to updater are required to recognize the burn addresses. Changes to updater can be a lenghtly review process as it touches the core, so probably in another PR. Which burn addresses can be a topic for debates @raphjaph

However, in this PR, I still include burn address constants for reviews

// satoshi first block address
 pub const MAINNET_BURN_ADDRESS: &'static str = "1FvzCLoTPGANNjWoUo6jUGuAG3wg1w4YjR";
 // just a random testnet address
 pub const TESTNET_BURN_ADDRESS: &'static str = "tb1prqr6lpxeqcyfff8n7c748ad7szyh8hwmf9nly598r5uqewkm4kms0nevay";
 // just a random regnet address
 pub const REGNET_BURN_ADDRESS: &'static str = "bcrt1pyf99p0qrt8dsx8a8hnd7edzpnnpsndf9ce6hhx55s9f9v84e48eqdlyd6n";

I implemented a generic burn in #3437. Can extend that to support runes?

[raphjaph]

I'll have a look at generic burning first (#3437) but probably we don't want to do protocol level burning through cenotaphs but rather by sending to an OP_RETURN.

[raphjaph]

I merged #3437, since burning through OP_RETURN is more generic and can be used for inscriptions, sats and runes.

@raphjaph After #3437 is it possible to burn runes via ord wallet? I am thinking about two scenarios:

• Burn a certain amount of a Rune
• Burn the "etching"

[onchainguy-btc]

Happy to work on this as well @raphjaph

Yes, burning a rune should be part of ord wallet burn command as well. It's already defined on the protocol level here: https://docs.ordinals.com/runes.html?highlight=burn#burning. So all we have to do is implement it. You should be able to specify the amount you want to burn.

For "etching" do you mean the optional parent inscription of the rune? This can already be done with the new command. @onchainguy-btc is tweaking it so it only burns a single sat instead of the whole utxo it is in.

Also this, but more destroying the rune itself, so it is totally trashed, no one can mint/transfer it anymore, would it make sense?

[raphjaph]

An etching can't retroactively destroy all runes it "minted". Once they are on Bitcoin they're no longer owned by the original creator

[gus4rs]

So once an etching is confirmed, it can't prevent new mints, or can't be modified in any shape or form, or even be "transferred" to another owner?

[raphjaph]

that's correct, only the parent (if it exists) can be transferred.
