We'd love to split the ECDSA signing operation into two steps:
- an "offline" step that is independent on the message,
- an "online" step that depends on the message.
The advantage here is that t…

The following Signature Operations require a check to distinguish between
Schnorr / DER Signatures using the Secp256k1 curve. I've submitted a PR for this
issue at https://github.com/rojii/bcash/com…

I'm proposing that we add an ecosystem proposal to support MuSig (or similar construction) for the purpose of having a single account key which requires signatures from multiple signers.
This is hi…

This will be necessary to support Schnorr-Ristretto or other signature schemes which @burdges is investigating.
As we generalize more work over signature schemes, it may prove useful to have a set …

nostr_dart uses the [bip340](https://pub.dev/packages/bip340) package (v0.0.4) for Schnorr signature verification but I'm finding the performance to be problematic. The UI on an app I'm building with …

Grin should already support in the near future:
* multisig using aggregate (formerly Schnorr) signatures ;
* time-locked transactions.
Using these primitives, figure out how to implement vaults…
