Deterministic Wallet Formats

Type 1: Single Chain Wallets

A Type 1 deterministic wallet is the simpler of the two, which can create a single series of keys from a single seed. A primary weakness is that if the seed is leaked, all funds are compromised, and wallet sharing is extremely limited.

Type 2: Hierarchical Deterministic (HD) Wallets
