The keys generated above are so called type-0 non-deterministic keys. That means that each one is generated from a random number generator. The sx tools also support type-2 deterministic keys, where a "master" key is created and then extended to produce a chain or tree of subkeys.

First, we generate a "seed" that will be used as the basis to derive a chain of keys, compatible with the Electrum wallet and other similar implementations.

With the seed, we can now generate a sequence of private and public keys, a key chain.

With deterministic keys we can generate and re-generate thousands of keys, all derived from a single seed in a deterministic chain. This technique is used in many wallet applications to generate keys that can be backed up and restored with a simple multi-word mnemonic. This is easier than having to back up the wallet with all its randomly generated keys every time a new key is created.
