## 📄 BlackSilk Blockchain — Post-Quantum Signature Integration Proposal

### 🧠 Motivation

With the future threat of quantum computing, it's essential to prepare cryptographic infrastructure for post-quantum security. As BlackSilk Blockchain is built from scratch in Rust, with a modular architecture and custom VM, it offers the perfect opportunity to integrate and experiment with post-quantum cryptography from the ground up.

The following is a proposal based on expert discussion (special thanks to @mraksoll) outlining a realistic integration plan for PQ signature schemes — especially for tokens, high-throughput use cases, and contract verification.
 
### 🔐 Proposal Overview

#### ✅ 1. Signature Scheme: ML-DSA (Dilithium)

-
Why Dilithium?

  - Efficient signature generation and verification.
  - Strong NIST Level 2+ security.
  - Ideal for tokens with many transactions.
  - Deterministic key generation from a seed is feasible.


-
Target use cases:

  - High-frequency token transfers.
  - Smart contracts that rely on signature verification.
  - Cold wallet key generation from seed phrases.

#### ✅ 2. Deterministic Key Generation

-
Falcon and Dilithium both expect entropy of:

  - Falcon512 → 48 bytes
  - Dilithium2 → up to 32 bytes (configurable)

-
Seed generation proposal:

  - Use
SHA384(passphrase)
or
SHA384(seed_phrase)
to generate fixed-length entropy.

  - SHA384 outputs exactly 48 bytes — ideal for Falcon512.
  - Security tradeoff is negligible since seed is private.

*"hash function SHA384 – simple to get correct format for feed it to keygen. since 48 bytes of entropy are expected by default." — @mraksoll*

 
### 🔧 Technical Integration Plan

#### 🔸 Keypair Generation

- Implement wrapper function:
fn keypair_from_seed(seed: &[u8]) -> (PublicKey, SecretKey)

- Extend PQClean / cryptoquick / libpqcrypto wrappers to support deterministic keypair derivation.
- Accept seed from wallet logic or RPC (encrypted in production).

#### 🔸 Signature Verification in Runtime / Contracts


- Add Dilithium / Falcon signature verification in:

  - Native runtime (WASM runtime or custom VM)
  - Or expose via syscall / precompiled contract (like EVM secp256k1)

- Optimize verification cost to make on-chain usage viable.

#### 🔸 Wallet Compatibility

- For now, BIP39 is incompatible with PQ signatures, but a custom single-key format can be used.
- Use a simplified derivation path like:
PQ-Wallet: SHA384(seed phrase) → 48-byte → Falcon512 keypair

*"bip39 possible stop work, need change it for now for single key logic if use PQ... at pq no exist bip39 "* — @mraksoll_

### 🚫 Known Limitations

-
Signature sizes:

  - Falcon512: ~666 bytes
  - Dilithium2: ~2.4 KB
  - SLH-DSA: >7 KB (not recommended for blockchain usage)

-
May impact storage/bandwidth for high-volume transaction blocks.

-
Contracts may require gas adjustment for verifying large signatures.

### 🧩 Optional Enhancements

- Add support for multiple schemes: Falcon (for coins), Dilithium (for tokens).
- Allow contract to specify accepted scheme type.
- Add PQ address formats to explorer and wallet frontend.

### ✅ Final Notes


BlackSilk Blockchain is designed from scratch. This allows us to fully integrate post-quantum cryptography without legacy constraints. With your contributions (e.g., modifying the libs to accept seed-based keygen), we can create a truly future-proof blockchain — one that leads in security, not follows.
