BIP-39 (Mnemonic Code)
Definition
BIP-39 is a standard for generating human-readable mnemonic seed phrases from cryptographic entropy. The 12-24 word phrases enable wallet backup and recovery. Post-quantum wallets adapt BIP-39 for quantum-resistant key derivation while maintaining familiar user experience.
Technical Explanation
BIP-39 converts 128-256 bits of entropy into 12-24 words from a 2048-word list. A checksum ensures valid phrases. The mnemonic converts to a 512-bit seed via PBKDF2-SHA512 with "mnemonic" + passphrase as salt. This seed initializes HD wallet key derivation.
Quantum resistance: the mnemonic format itself is secure—2048²⁴ combinations resist even Grover-accelerated guessing. The derived keys must use quantum-resistant algorithms. BIP-39's general approach works; the downstream derivation adapts for post-quantum keys.
SynX Relevance
SynX uses BIP-39 compatible seed phrases for wallet backup. Your familiar 24-word phrase secures quantum-resistant Kyber-768 and SPHINCS+ keys. The recovery experience matches classical wallets while providing post-quantum protection for all derived keys.
Frequently Asked Questions
- Can I use my existing BIP-39 phrase with SynX?
- Importing is possible, but new quantum-resistant keys derive differently. Best practice: generate fresh phrases for SynX.
- Are 12 words enough for quantum resistance?
- 12 words (128 bits) becomes 64-bit quantum security. 24 words (256 bits, 128-bit quantum) is recommended.
- Should I add a passphrase?
- Optional passphrases add protection if your phrase is compromised. Remember it—no recovery without it.
