Changes:
- Unified error types (`PoseidonError`, `HashError`, etc.) across
hashing, keygen, witness calculation, and serialization for consistent
and descriptive error handling.
- Refactored tests and examples to use `unwrap()` where safe, and
limited `expect()` in library code to non-panicking cases with clear
messaging.
- Improved witness and proof generation by removing panicking code paths
and enforcing proper error propagation.
- Cleaned up outdated imports, removed unused operations in `graph.rs`,
and updated public API documentation.
- Updated C, Nim, and WASM FFI bindings with more robust serialization
and clearer error log messages.
- Added keywords to package.json and update dependencies in
Makefile.toml and Nightly CI.
# 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repo, updated outdated RLN RFC link.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.

- Resolved overlap between stateless and merkletree feature flags.
- Updated every testcase related to stateless feature.
- Added compile-time feature check to avoid feature overlap.
- Added --no-default-features for all builds in nightly-release.yml
[(tested)](https://github.com/vacp2p/zerokit/actions/runs/16525062203).

- Integrated missing options for generating feature-specific binaries
[(tested)](https://github.com/vacp2p/zerokit/actions/runs/16408191766).
- Made arkzkey the default feature for improved consistency.
- Created a script to convert arkzkey from zkey.
- Updated nightly-release.yaml file.
- Updated documentation.
# 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.
Trying out ideas to solve problems from this [Discord
conversation](https://discord.com/channels/864066763682218004/1344911294092017716):
- Completely remove the verification key file and use `vk_from_raw` or
derive it from ZK.
- To handle tree height mismatches, improve the documentation to provide
users with clear guidelines, preventing the generation of an incorrect
`graph.bin` file.
- Remove compressed `ark-zkey` usage and conduct benchmarking and
testing.
- Add documentation for the specific Circom compiler version 2.1.0.
- Update documentation on `rln.circom` parameters `N` and `M`.

Brought back functionality that was removed during the migration to
iden3
- Modify circuit module to include graph data loading and calculation
- Update RLN struct to store graph data
- Adjust proof generation and FFI methods to use graph data
- Update benchmarks and tests to use sample size instead of measurement
time
- Add new methods for graph data retrieval and handling
ark-circom update their branch to new dependency version and we can't
support it right now. So I pin it on previous commit
also during the local testing I find out that cargo make doesn't work
correctly with new rln-cli examples (it calls "cargo" "build"
"--all-features") and it's wrong behaviour
Fix Configuration Handling:
+ Document the expected format of the configuration file.
+ Provide an example configuration file in rln-cli to guide users.
+ Ensure that the CLI provides useful error messages if the
configuration is missing or incorrect.
Implement Relay and Stateless RLN Examples
+ Add Relay example to illustrate RLN’s practical use case.
+ Add Stateless RLN example, where an externally built Merkle tree
provides paths and roots for RLN stateless feature.
