8f5b172e59b4d5e199b98777855b0d9b46742f66 test(wallet): verify wallet panics in dev mode if using keychains with duplicate spks (Steve Myers) 46c6f18cc3ff71efda2b8547aa32854f9b88762e refactor(chain): calculate DescriptorId as sha256 hash of spk at index 0 (Steve Myers) Pull request description: ### Description Rename `DescriptorId` to `KeychainId` and `descriptor_id()` to `keychain_id()`. Calculate keychain ids as the hash of the spk derived from its descriptor as index 0. Added docs to `Wallet` and `KeychainTxOutIndex::insert_descriptor()` explaining that it's the users responsibility not to use wildcard and non-wildcard descriptors that can derive the same script pubkey. I also recommended for `Wallet` that legacy non-wildcard descriptors be added to a temporary `Wallet` and swept into a modern wildcard descriptor. ### Notes to the reviewers fixes #1483 ### Changelog notice changed - Renamed DescriptorId to KeychainId, DescriptorExt::descriptor_id() to keychain_id(). ### Checklists #### All Submissions: * [x] I've signed all my commits * [x] I followed the [contribution guidelines](https://github.com/bitcoindevkit/bdk/blob/master/CONTRIBUTING.md) * [x] I ran `cargo fmt` and `cargo clippy` before committing #### Bugfixes: * [ ] This pull request breaks the existing API * [ ] I've added tests to reproduce the issue which are now passing * [x] I'm linking the issue being fixed by this PR ACKs for top commit: LLFourn: ACK 8f5b172e59b4d5e199b98777855b0d9b46742f66 oleonardolima: Concept ACK 8f5b172e59b4d5e199b98777855b0d9b46742f66 Tree-SHA512: 07defa208d9cfcd61bc6e31ded06a287c392c51bcc4949f601ecfac635c3443e7d08c62d92618ed894dc5ef13cdcf784771a6bf8904a5397110bedb1563f52d4
The Bitcoin Dev Kit
BDK
A modern, lightweight, descriptor-based wallet library written in Rust!

About
The bdk libraries aims to provide well engineered and reviewed components for Bitcoin based applications.
It is built upon the excellent rust-bitcoin and rust-miniscript crates.
⚠ The Bitcoin Dev Kit developers are in the process of releasing a
v1.0which is a fundamental re-write of how the library works. See for some background on this project: https://bitcoindevkit.org/blog/road-to-bdk-1/ (ignore the timeline 😁) For a release timeline see theBDK 1.0 project page.
Architecture
The project is split up into several crates in the /crates directory:
wallet: Contains the central high levelWallettype that is built from the low-level mechanisms provided by the other componentschain: Tools for storing and indexing chain datapersist: Types that define data persistence of a BDK walletfile_store: A (experimental) persistence backend for storing chain data in a single file.esplora: Extends theesplora-clientcrate with methods to fetch chain data from an esplora HTTP server in the form thatbdk_chainandWalletcan consume.electrum: Extends theelectrum-clientcrate with methods to fetch chain data from an electrum server in the form thatbdk_chainandWalletcan consume.
Fully working examples of how to use these components are in /example-crates:
example_cli: Library used by theexample_*crates. Provides utilities for syncing, showing the balance, generating addresses and creating transactions without using the bdk_walletWallet.example_electrum: A command line Bitcoin wallet application built on top ofexample_cliand theelectrumcrate. It shows the power of the bdk tools (chain+file_store+electrum), without depending on the mainbdk_walletlibrary.example_esplora: A command line Bitcoin wallet application built on top ofexample_cliand theesploracrate. It shows the power of the bdk tools (chain+file_store+esplora), without depending on the mainbdk_walletlibrary.example_bitcoind_rpc_polling: A command line Bitcoin wallet application built on top ofexample_cliand thebitcoind_rpccrate. It shows the power of the bdk tools (chain+file_store+bitcoind_rpc), without depending on the mainbdk_walletlibrary.wallet_esplora_blocking: Uses theWalletto sync and spend using the Esplora blocking interface.wallet_esplora_async: Uses theWalletto sync and spend using the Esplora asynchronous interface.wallet_electrum: Uses theWalletto sync and spend using Electrum.
Minimum Supported Rust Version (MSRV)
This library should compile with any combination of features with Rust 1.63.0.
To build with the MSRV you will need to pin dependencies as follows:
cargo update -p zstd-sys --precise "2.0.8+zstd.1.5.5"
cargo update -p time --precise "0.3.20"
cargo update -p home --precise "0.5.5"
cargo update -p proptest --precise "1.2.0"
cargo update -p url --precise "2.5.0"
