What is TSN?

Trust Stack Network is a Layer 1 blockchain designed from the ground up for privacy and post-quantum security. Every transaction is shielded by default using zero-knowledge proofs, and all cryptographic primitives are quantum-resistant — protecting funds against both classical and future quantum adversaries.

Key Features

Feature	Description
Plonky2 STARKs	Hash-based zero-knowledge proofs — no trusted setup, truly post-quantum
ML-DSA-65 (FIPS 204)	NIST post-quantum digital signatures for all transactions and blocks
SLH-DSA (FIPS 205)	Stateless hash-based signatures as secondary post-quantum layer
Poseidon2	ZK-friendly hash function over the Goldilocks field, 3x faster than Poseidon
Shielded Transactions	Amounts and addresses hidden by default via ZK commitments and nullifiers
UTXO Model	Bitcoin-inspired unspent transaction outputs with privacy
MIK Consensus	Mining Identity Key — Proof of Work with anti-Sybil protection
Kademlia DHT	Decentralized peer discovery with gossip-based block propagation

Security Model

TSN is designed to be fully quantum-safe — not just signatures, but the entire transaction privacy stack:

Attack Vector	Protection
Forge signatures	ML-DSA-65 (NIST PQ standard)
Break ZK proofs	Plonky2 STARKs (hash-based, no elliptic curves)
Crack commitments	Poseidon over Goldilocks field
Brute force hashes	Poseidon2 (256-bit security)
Sybil mining	MIK identity bound to blockchain

Mining Identity Key (MIK)

Every miner must register a Mining Identity Key before mining:

• Derived from their ML-DSA-65 public key: MIK_ID = SHA-256("TSN_MIK_ID_v1" || pubkey || block_height)
• One active MIK per public key — prevents Sybil attacks
• Lifecycle: registration → activation delay (10 blocks) → active → optional expiry/revocation
• Block signatures verified against the miner's registered MIK

Roadmap

Phase 1 — Foundations ✅

Core blockchain engine: blocks, transactions, UTXO, Poseidon2 hashing, ML-DSA-65 signatures, Proof of Work consensus with MIK anti-Sybil, P2P networking with Kademlia DHT, SledDB storage, shielded wallet, JSON-RPC API, block explorer, and testnet faucet.

Phase 2 — Advanced Features (In Progress)

Multi-role nodes (Miner, Relay, Prover, Light Client), Plonky3 STARK migration (replacing legacy Groth16/Halo2), browser-based WASM prover, and enhanced shielded wallet with viewing keys.

Phase 3 — Smart Contracts

zkVM (zero-knowledge virtual machine) for executing smart contracts inside ZK proofs. Multi-asset UTXO support, TSN-20 token standard, and Ethereum bridge via light client verification.

Phase 4 — Launch
