Token Tact employs a hybrid encryption model combining AES-256-GCM for symmetric data encryption and Curve25519 for asymmetric key exchange. This pairing ensures that transaction payloads and user metadata remain confidential even if network nodes are compromised. Each session generates ephemeral keys, preventing replay attacks and limiting exposure from key compromise. The network’s architecture on token-tact.net mandates that all communication between wallets and nodes passes through authenticated encryption channels, validated by hardware-backed secure enclaves on supported devices.
Key derivation follows the BIP32 standard with a twist: the master seed is combined with a network-specific salt derived from the genesis block hash. This prevents cross-chain key reuse attacks. For asset transfers, each output is encrypted with a unique derived key, ensuring that even if one transaction is decrypted, past and future transactions remain secure. The system also implements forward secrecy-compromising a session key does not reveal previous session keys.
Token Tact integrates zk-SNARKs (Groth16) to verify transaction validity without revealing sender, receiver, or amount. The proving key is generated via a multi-party computation ceremony with over 200 participants, ensuring no single party can forge proofs. Verification requires less than 10ms on consumer hardware, making it practical for real-time settlements. Shielded pools allow users to opt into full privacy, while transparent pools maintain regulatory compliance for institutions.
The network operates three distinct encryption layers: transport layer (TLS 1.3 with custom cipher suites), consensus layer (BLS signatures aggregated per block), and application layer (homomorphic encryption for smart contract state). This separation means a vulnerability in one layer does not cascade. For example, even if TLS is broken, the application data remains encrypted with keys unknown to the transport layer.
Node-to-node communication uses Noise Protocol Framework with the XX handshake pattern, providing mutual authentication and resistance to man-in-the-middle attacks. Validators rotate encryption keys every 100 blocks, and old keys are cryptographically erased. The staking mechanism requires validators to post collateral that can be slashed if they attempt to decrypt user data without authorization.
Token Tact includes a hybrid KEM (Key Encapsulation Mechanism) combining X25519 and CRYSTALS-Kyber. Users can optionally activate quantum-safe mode, which doubles key sizes but ensures protection against Shor’s algorithm. The network plans to fully migrate to FALCON signatures by 2027, with backward compatibility for legacy keys.
All encryption modules are formally verified using the Coq proof assistant, covering 94% of code paths. Third-party audits by Trail of Bits and NCC Group confirmed no cryptographic weaknesses. The network publishes a transparency report quarterly, listing all protocol upgrades and their impact on encryption standards. Users can verify encryption proofs via a public block explorer that shows merkleized commitment trees without exposing private data.
For recovery, Token Tact implements social key sharding (Shamir’s Secret Sharing with 3-of-5 threshold) combined with biometric-hardened passkeys. Lost keys can be reconstructed without exposing the master seed to any single party. The system also supports hardware security module (HSM) integration for enterprise custodians.
Private keys are encrypted using AES-256-GCM with a key derived from the user’s password via Argon2id (memory-hard KDF). The encrypted blob is stored locally, never on servers.
Yes, through social key recovery (3-of-5 Shamir shares) combined with biometric verification. No single entity holds enough information to reconstruct the key.
Each transaction includes a unique nonce derived from the sender’s key and a timestamp. Nodes reject transactions with duplicate nonces within the same epoch.
Yes. The network supports selective disclosure via zero-knowledge proofs, allowing users to prove compliance (e.g., KYC status) without revealing personal data.
Token Tact’s hybrid KEM (X25519 + Kyber) provides immediate resistance. A full migration to FALCON signatures is scheduled for 2027.

I audited the zk-SNARK circuit. The proving key ceremony was exceptionally transparent-over 200 participants across 6 continents. No backdoors found.

We moved $50M in assets to Token Tact after verifying their HSM integration and multisig recovery. The forward secrecy feature sealed the deal.

Finally a network that treats encryption as a first-class citizen, not an afterthought. The shielded pools work exactly as documented.
