HD Wallet (Hierarchical Deterministic)
Definition
An HD wallet generates all addresses and keys from a single master seed using deterministic derivation. This enables single-backup recovery, organized key hierarchies, and unlimited address generation. Post-quantum HD wallets extend this concept with Kyber and SPHINCS+ key derivation.
Technical Explanation
Classical HD wallets (BIP-32/44) derive keys using hierarchical paths: m/purpose'/coin'/account'/change/index. Each path level generates child keys from parent keys. The master seed (from your seed phrase) sits atop the hierarchy, enabling complete wallet reconstruction.
Post-quantum HD derivation adapts these concepts for larger keys. Kyber-768 and SPHINCS+ key pairs derive from path-indexed seeds. The hierarchy provides organization (accounts, addresses) while determinism ensures recoverable backups.
SynX Relevance
SynX implements HD wallet functionality for quantum-resistant keys. One seed phrase generates unlimited Kyber-768 and SPHINCS+ key pairs organized hierarchically. You can create multiple accounts, generate fresh addresses for each transaction, and recover everything from your single backup.
Frequently Asked Questions
- Why use HD instead of random addresses?
- HD enables single backup, organized accounts, and fresh addresses without managing many separate keys.
- Can I share my HD public key?
- Extended public keys allow generating receive addresses without spending capability—useful for watch-only wallets.
- Do post-quantum HD wallets use BIP-32?
- Modified versions—same principles but adapted for larger quantum-resistant key derivation.
