Build Rust SDK to support user applications

[gregdhill]

Abstract

We already provide a Typescript SDK for inscribing and transferring Ordinals, this uses Esplora (Electrs) as a back-end to fetch blocks and transactions. There is interest in using Rust to develop tooling for BOB since many useful libraries exist so we should provide a Rust SDK that achieves the same functionality.

Motivation

We aim to use Risc Zero to support Rust smart contracts in the future.

Specification

The idea would be to introduce a Rust crate, structured similarly to the TS SDK, that uses the rust-bitcoin dependencies to abstract inscribing and transferring Ordinals (and more!). We can also use the bdk library for wallet functionality and re-use code from the Ord project since that is also written in Rust. There is also a lot of relevant code written for interbtc-clients that interfaces with Bitcoin Core and Electrs that we can use.
