BDK Chain

BDK keychain tracker, tools for storing and indexing chain data.

lib.rs:

This crate is a collection of core structures for Bitcoin Dev Kit.

The goal of this crate is to give wallets the mechanisms needed to:

1. Figure out what data they need to fetch.
2. Process the data in a way that never leads to inconsistent states.
3. Fully index that data and expose it to be consumed without friction.

Our design goals for these mechanisms are:

1. Data source agnostic -- nothing in bdk_chain cares about where you get data from or whether you do it synchronously or asynchronously. If you know a fact about the blockchain, you can just tell bdk_chain's APIs about it, and that information will be integrated, if it can be done consistently.
2. Data persistence agnostic -- bdk_chain does not care where you cache on-chain data, what you cache or how you retrieve it from persistent storage.
