Full Changelog: v0.10.0...v0.11.1

v0.10.0

Charms v0.10.0 brings native coins visibility to app contracts. Combined with Scrolls this enables smart contracts on Bitcoin that can lock and unlock BTC.

This release also completes the ground work necessary for Charms being represented on Cardano as CNTs.

Also, Charms can now be securely beamed from Bitcoin to... currently only Bitcoin (but also any other chains, when we add support for them). Great news is: now adding support for Bitcoin clones is straightforward, so now Litecoin and Dogecoin can be added almost trivially.

What's Changed

• Native coin handling in spells by @imikushin in #127
• Prepare v0.10 release by @imikushin in #133

Full Changelog: v0.9.3...v0.10.0

v0.8.0 - Proper mocks

What's New

• Charms protocol version 6 is now the current version
• charms-lib Wasm module for use both in browser and backend runtimes like Node.js and Deno
  • Find charms_lib.wasm in this release's artifacts
  • Generate JS bindings for it using wasm-bindgen --out-dir target/wasm-bindgen-nodejs --target nodejs ./charms_lib.wasm
• Proper mocks:
  • Use --mock flag in charms CLI commands to generate and verify mock proofs
  • mock: bool param in charms-lib's extractAndVerifySpell(tx, mock)

Full Changelog: v0.7.0...v0.8.0

v0.7.0 - Wasm app contracts

What's New

• Charms apps compile to Wasm modules (using WASI Preview 1 spec, with --target=wasm32-wasip1).
  • charms app build builds prints the Wasm module file name to stdout.
  • charms app vk now simply computes SHA-256 hash of the Wasm module and thus no longer depends on the underlying zkVM.

What's Changed

• charms_data::Transaction now lists inputs as Vec<(UtxoId, Charms)> (vs BTreeMap<UtxoId, Charms> before v0.7.0)
