hotmint-crypto

Cryptographic implementations for the Hotmint BFT consensus framework.

Provides concrete implementations of the Signer and Verifier traits defined in hotmint-types, using Ed25519 for digital signatures and Blake3 for block hashing.

Components

Component	Description
`Ed25519Signer`	Implements `Signer` using ed25519-dalek
`Ed25519Verifier`	Implements `Verifier` for single and aggregate signature verification
`hash_block()`	Blake3 hashing of block fields

Usage

use hotmint_types::{Signer, ValidatorId};
use hotmint_crypto::{Ed25519Signer, Ed25519Verifier};

// Generate a random keypair
let signer = Ed25519Signer::generate(ValidatorId(0));

// Sign a message
let sig = signer.sign(b"hello");
let pk = signer.public_key();

// Verify
let verifier = Ed25519Verifier;
assert!(verifier.verify(&pk, b"hello", &sig));

Construct from existing key

use ed25519_dalek::SigningKey;

let signing_key = SigningKey::from_bytes(&secret_key_bytes);
let signer = Ed25519Signer::new(signing_key, ValidatorId(0));

Block hashing

use hotmint_crypto::hash_block;
use hotmint_types::{Height, BlockHash, ViewNumber, ValidatorId};

let hash = hash_block(
    Height(1),
    &BlockHash::default(),
    ViewNumber(0),
    ValidatorId(0),
    b"payload",
);
