# Changes
- Unified the `RLN` struct and core protocol types across public, FFI,
and WASM so everything works consistently.
- Fully refactored `protocol.rs` and `public.rs` to clean up the API
surface and make the flow easier to work with.
- Added (de)serialization for `RLN_Proof` and `RLN_ProofValues`, and
matched all C, Nim, WASM, and Node.js examples.
- Aligned FFI and WASM behavior, added missing APIs, and standardized
how witness are created and passed around.
- Reworked the error types, added clearer verification messages, and
simplified the overall error structure.
- Updated variable names, README, Rust docs, and examples across the
repo, updated outdated RLN RFC link.
- Refactored `rln-cli` to use the new public API, removed
serialize-based cli example, and dropped the `eyre` crate.
- Bumped dependencies, fixed CI, fixed `+atomic` flags for latest
nightly Rust and added `Clippy.toml` for better fmt.
- Added a `prelude.rs` file for easier use, cleaned up public access for
types and types import across zerokit modules.
- Separated keygen, proof handling, slashing logic, and witness into
protocol folder.
- separated all identity generation functions as separate functions,
rather than RLN methods
- added BE support - only for these functions so far
- covered the functions with tests, as well as conversion to big endian
- prepared for publication, but is actually awaiting the initial
publication of the RLN module
@vinhtc27, please check that everything is correct from the wasm point
of view. This module does not require parallel computing, so if there
are any unnecessary dependencies, builds, etc., please let me know.

# Bring Back WebAssembly Support for ZeroKit
- Update minor versions of all dependencies.
- Update documentation to reflect these changes.
- ~~Vendor `wasmer` v4.4.0 in [my git
repository](https://github.com/vinhtc27/wasmer) for `ark-circom`
v0.5.0.~~
- Resolve `wasm-pack` build failures (`os error 2`) caused by a Node.js
version mismatch.
- Restore the previous CI pipeline for the `rln-wasm` feature and update
to the stable toolchain.
- ~~Use `ark-circom` with the `wasm` feature for WebAssembly
compatibility and the `rln.wasm` file for witness calculation.~~
- ~~Fix dependency issues related to `ark-circom` v0.5.0, which
currently uses `wasmer` v4.4.0 and is affected by this
[issue](https://github.com/rust-lang/rust/issues/91632#issuecomment-1477914703).~~
- Install WABT with `brew` and `apt-get` instead of cloning to fix
`wasm-strip not found` issue in the CI workflow.
- Install `wasm-pack` with `curl` instead of using `wasm-pack-action` to
fix parse exception error in the CI workflow.
- Use the `.wasm` file with JS bindings for witness calculation, which
is generated from [`iden3/circom`](https://github.com/iden3/circom)
during circuit compilation. This allows witness computation outside RLN
instance.
- Refactor the `rln` module by moving circuit-related files to the
`src/circuit` folder for better organization.
- Remove `ark-circom` and `wasmer` by cloning the
[CircomReduction](3c95ed98e2/src/circom/qap.rs (L12))
struct and the
[read_zkey](3c95ed98e2/src/zkey.rs (L53))
function into the `rln` module, which reduces the repository's build
size and speeds up compilation time and the CI workflow duration.
- These change also address
[#282](https://github.com/vacp2p/zerokit/issues/282) by removing
`wasmer` and `wasmer-wasix`, which lack x32 system support.
- Benchmark `rln-wasm` with `wasm_bindgen_test`, covering RLN instance
creation, key generation, witness calculation, proving, and
verification. Also, add them to `v0.6.1` in
[benchmark-v0.6.1](https://github.com/vacp2p/zerokit/tree/benchmark-v0.6.1)
for comparison.
- Add `arkzkey` feature for rln-wasm, including tests, benchmarks, CI
workflow updates, and related documentation.
- Benchmark rln-wasm in the browser using HTML, covering initialization,
RLN instance creation, proving, and verification; fork to the
`benchmark-v0.7.0` branch for later use
[here](https://github.com/vacp2p/zerokit/tree/benchmark-v0.7.0).
- Fix clippy error: "this `repeat().take()` can be written more
concisely" on CI workflow for `utils` module.
([error](https://github.com/vacp2p/zerokit/actions/runs/14258579070/job/39965568013))
- Update Makefile.toml to be able to run `make build`, `make test`, and
`make bench` from root and inside each modules.
* chore: Update dependencies to latest versions
Upgrade various dependencies across multiple crates to their latest compatible versions
* chore: Update Cargo.toml dependency versions to latest compatible releases
Upgrade serde and serde_json dependency versions using more flexible version specifiers
* chore: Update Cargo dependencies to latest compatible versions
Upgrade Ark and Wasmer dependencies to their latest minor versions, including:
- ark-circom from 0.1.0 to 0.5.0
- ark-zkey from 0.1.0 to 0.1.2
- wasmer from 2.3.0 to 2.3.x
- num-traits to 0.2.19
Also update Makefile to improve cross-platform build process for wabt
* chore: Update Ark dependencies to latest patch versions
* chore: Revert ark-zkey dependency and update Wasmer to 4.4.0
Remove ark-zkey optional dependency and update Wasmer to version 4.4.0 across multiple crates. Modify circuit module to include necessary structs and functions previously provided by ark-zkey.
* chore: Update zkey path to use uncompressed arkzkey file
* Remove rln-wasm package and related configurations
Clean up project structure by removing the rln-wasm package, associated GitHub workflows, and WASM-specific configurations. This includes:
- Removing rln-wasm directory and its contents
- Updating Cargo.toml workspace configuration
- Removing WASM-specific build and test configurations from CI workflows
- Removing WASM-related dependencies and features from RLN crate
* Fix CI workflow for default feature testing
* rollback to default
* Fix CI workflow to support default feature testing
* Fix CI workflow syntax for feature testing condition
* Update README.md with clearer testing instructions for RLN module
Since profile info specified inside workspace members `Cargo.toml`'s
is ignored by Cargo, this replaces the place to specify these details
for the workspace-level `Cargo.toml`.
NOTE that `panic` and `rpath` aren't supported with the Overwritting
feature. Therefore, the only required thing (if considered necessary) is
to create a new profile which also enables these things.
Resolves: #93
