Feature flags of Ligerito crate // Lib.rs

Cargo Features

[dependencies]
ligerito = { version = "0.6.2", default-features = false, features = ["serde", "scale", "std", "prover", "verifier-only", "parallel", "hardware-accel", "transcript-sha256", "transcript-merlin", "transcript-blake2b", "substrate", "wasm", "wasm-parallel", "wasm-raw", "webgpu", "cli"] }

Default is full-featured std environment with prover + verifier + CLI Uses SHA256 transcript by default (no extra deps, works everywhere)

default = cli, hardware-accel, parallel, prover, std

These default features are set whenever ligerito is added without default-features = false somewhere in the dependency tree.

serde std

Serialization support (optional - not needed for wasm-lite)

Enables serde and serde of ligerito-binary-fields and ligerito-merkle

ligerito-binary-fields:
Core dependencies (always needed)

scale

SCALE codec for Substrate runtime (no_std compatible)

Enables scale-info, scale of ligerito-binary-fields and ligerito-merkle and parity-scale-codec

SCALE codec for Substrate runtime support

std default cli transcript-merlin? wasm? wasm-raw? = serde, thiserror

Environment: std or no_std

Enables std of optional parity-scale-codec, ligerito-binary-fields, ligerito-merkle, optional ligerito-reed-solomon, optional scale-info, and optional serde

ligerito-reed-solomon:
Prover-only dependencies

Affects autosizer::print_config_summary, ligerito::autosizer, ligerito::LigeritoError, transcript::Transcript…

prover default cli wasm? wasm-raw? = ligerito-reed-solomon, rand, rand_chacha

Functionality: include prover or verifier-only

verifier-only

parallel default cli wasm-parallel? = rayon

Performance optimizations

Enables parallel of optional ligerito-reed-solomon

Affects sumcheck_polys::induce_sumcheck_poly_parallel, ligero::encode_cols…

hardware-accel default cli wasm? wasm-raw?

Enables hardware-accel of ligerito-binary-fields and optional ligerito-reed-solomon

transcript-sha256 cli wasm? wasm-raw?

Transcript implementations
SHA256 is always available (default) - no extra dependencies, works in no_std Default: minimal deps, works everywhere including WASM

transcript-merlin cli wasm? = merlin, std

Merlin transcript (Zcash/Dalek standard)

Affects transcript::MerlinTranscript, verifier::verify_complete…

transcript-blake2b substrate? wasm? = blake2

BLAKE2b transcript (optimized for Substrate)

Affects prover::prove_blake2b, transcript::Blake2bTranscript, verifier::verify_blake2b, verifier::verify_complete_blake2b…

substrate = sp-io, transcript-blake2b

Substrate runtime support - uses BLAKE2b with sp_io host functions

wasm wasm-parallel? webgpu? = bincode, console_error_panic_hook, hardware-accel, js-sys, prover, std, transcript-blake2b, transcript-merlin, transcript-sha256, wasm-bindgen, wasm-bindgen-futures

WASM support (full - includes serde/bincode for proof serialization)

Enables js of getrandom ^0.2

Affects ligerito::wasm…

wasm-parallel = js-sys, parallel, wasm, wasm-bindgen-rayon

Multi-threaded WASM (requires SharedArrayBuffer + CORS headers)

wasm-raw = bincode, hardware-accel, prover, std, transcript-sha256

Raw WASM - no wasm-bindgen, just extern "C" exports Use this for manual multi-instance parallelism or minimal bindings Note: Uses custom random seeding from JS instead of getrandom

Enables custom of getrandom ^0.2

Affects ligerito::wasm_raw…

webgpu = futures, pollster, wasm, web-sys, wgpu

WebGPU acceleration (optional, falls back to WASM if unavailable)

Affects backend::GpuBackend, gpu::device, gpu::fft, gpu::sumcheck, gpu::buffers, gpu::shaders, gpu::is_webgpu_available, ligerito::gpu…

cli default = anyhow, bincode, clap, core_affinity, hardware-accel, hex, parallel, prover, serde_json, std, transcript-merlin, transcript-sha256

"std",
"prover",
"polkavm",
"polkavm-common",
]

CLI binary support - includes ALL features for maximum capability Why hold back? Users want the full power!

Required by the binary

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

merlin transcript-merlin?

blake2 transcript-blake2b?

sp-io substrate?
