bp-core's Issues

Compilation fails on Rust v1.64

Looks like bp-core (more precisely bp-seals) fails to compile on Rust 1.64 (stable). To confirm this, I've tried every minor version from 1.59 and the build succeeds on every one of them except for 1.64.

$ rustup default 1.64 # or stable
info: using existing install for '1.64-x86_64-apple-darwin'
info: default toolchain set to '1.64-x86_64-apple-darwin'

  1.64-x86_64-apple-darwin unchanged - rustc 1.64.0 (a55dd71d5 2022-09-19)

TapLeafHash error？ 

impl TapLeafHash {
    pub fn with_leaf_script(leaf_script: &LeafScript) -> Self {
        let mut engine = Sha256::from_tag(MIDSTATE_TAPLEAF);
        engine.input_raw(&[leaf_script.version.to_consensus_u8()]);
        engine.input_with_len::<U32>(leaf_script.script.as_slice());
        Self(engine.finish().into())
    }

    pub fn with_tap_script(tap_script: &TapScript) -> Self {
        let mut engine = Sha256::from_tag(MIDSTATE_TAPLEAF);
        engine.input_raw(&[TAPROOT_LEAF_TAPSCRIPT]);
        engine.input_with_len::<U32>(tap_script.as_slice());
        Self(engine.finish().into())
    }
}

The function with_leaf_script directly uses a slice of the script as part of constructing the hash. However, according to BIP341, it is required to use the script encoded with CompactSize before including it in the hash. The actual difference is that the length prefix is missing, which results in a different value for the Merkle tree root compared to the standard approach.

TxStatus

In bp-esplora-client, there's a TxStatus type, but it's slightly different than the one used in bp-wallet. Compare:

https://github.com/BP-WG/bp-esplora-client/blob/689eb8f93282c69a77c98f878492f0726c5d5fe4/src/api.rs#L46-L52

And:

https://github.com/BP-WG/bp-wallet/blob/e8aa19d8475b14392ae7f1d9dfad1f41e0690056/src/data.rs#L95-L130

The bp-wallet enum has the same data, but it's a slightly different type. I actually prefer the richer type. Should we include it in bp-core so we can use it in both bp-wallet and bp-esplora-client?

If so, where should it go?

Support Liquid and prospective layer 1 (Prime etc)

In order to abstract single-use-seals from a specific bitcoin layer 1 we should:

  • Add supported chains to Chain type
  • Create a non-exhaustive enumeration single-use seal type which lists possible seal formats
  • Ensure single-use-seals always commit to the chain in its definition

Add OpRet commitments to the library

@zoedberg: can you please move the current implementation of the opret commitments in RGB here? I can't find in which library they do exist today, and I think they must be happening in the same place as tapret commitments (i.e. in this library).

Baid58 parse to TapretCommitment not work

Hi @dr-orlovsky,

I tried use baid58 parse to TapretCommitment and received the follow error:

running 1 test
thread 'tapret::tapscript::test::commiment_serialization' panicked at 'exact size match: Decode(Io(Kind(InvalidInput)))', dbc/src/tapret/tapscript.rs:66:10

Test Code

#[test]
pub fn tapret_commitment_baid58() {
    let commitment = commitment();
    let _ =  TapretCommitment::from_baid58(commitment.to_baid58()).unwrap();
}
