[TOR] HIDDEN SERVICE v3

Onion v3 Hidden Service Engineering

v3 Protocol Stack

Next-generation Tor hidden service cryptography:

Host key: Ed25519 (faster + secure)
Encryption: AES-256-GCM
Authentication: Curve25519 + HSv3 intro
Address length: 56 characters (.onion)
Rendezvous: Double handshake protocol

Ed25519 private key → BLAKE2b → Base32 → nexusplace2026hubxxxxxxxxxxxxx.onion

Distributed Architecture

5-node geographically redundant cluster:

Europe: nexusplace2026secy... (primary EU)
North America: nexusplace2026bak1... (primary NA)
Asia-Pacific: nexusplace2026bak2... (primary APAC)
Global Primary: nexusplace2026hub... (load balanced)
Emergency: nexusplace2026emg... (DDoS fallback)

Circuit Isolation

Per-session Tor circuit engineering:

New 6-hop circuit per login
Entry guards rotated daily
Rendezvous point isolation
30-minute circuit lifetime
HSv3 intro point rotation

Hidden Service v3 Specifications

Parameter	Value	Purpose
Version	HSv3 (RFC)	Current standard
Key Type	Ed25519	Host authentication
Key Length	32 bytes	Private key
Hash	BLAKE2b-512	Address derivation
Encryption	AES-256-GCM	Channel protection
DH Key Exchange	Curve25519	Perfect forward secrecy

[CRYPTO] PGP 4096-bit

Challenge-Response Authentication

2FA Protocol

Zero-knowledge proof of private key possession:

1. Server → Encrypt(random_challenge, nexus_pubkey) 2. Client → Decrypt(challenge, user_privkey) 3. Client → Sign(challenge_response, user_privkey) 4. Server → Verify(signature, user_pubkey)

Ephemeral challenge per session
4096-bit RSA modulus
SHA512 digest algorithm
15-minute token validity

Cryptographic Parameters

Enterprise-grade key generation:

Modulus: 4096-bit RSA (2^4096 security)
Exponent: 65537 (F4 standard)
Hash: SHA512 (512-bit digest)
Padding: PSS (provably secure)
Subkeys: 4096-bit (sign/encrypt/auth)

[PAYMENTS] RINGCT v2

2-of-3 Multisig Escrow

Multisig Protocol

Cryptographic escrow guarantees:

Buyer (1/3) → Funds locked
Vendor (1/3) → Delivery proof
Moderator (1/3) → PGP arbitration
2/3 signatures → Final settlement

Stealth Addresses

One-time use per transaction:

R privkey → one-time pubkey
Sender sees only destination pubkey
Receiver scans all outputs
Prevents address clustering

Ring Signatures

RingCT v2 anonymity set:

Ring size: 16 (effective ~11)
Pedersen commitments
Range proofs (Bulletproofs)
Confidential transactions
