@ -24,9 +24,9 @@ Bitcoin wallets contain keys, not coins. Each user has a wallet containing keys.
((("JBOK wallets")))((("wallets", "JBOK wallets")))((("nondeterministic wallets", seealso="wallets")))The first type is _nondeterministic wallets_, where each key is independently generated from a random number. The keys are not related to each other. This type of wallet is also known as a JBOK wallet from the phrase "Just a Bunch Of Keys."
((("deterministic wallets", seealso="wallets")))The second type of wallet is a _deterministic wallet_, where all the keys are derived from a single master key, known as the _seed_. All the keys in this type of wallet are related to each other and can be generated again if one has the original seed. There are a number of different _key derivation_ methods used in deterministic wallets. The most commonly used derivation method uses a tree-like structure and is known as a _hierarchical deterministic_ or _HD_ wallet.

((("key derivation methods")))There are a number of different _key derivation_ methods used in deterministic wallets. ((("hierarchical deterministic (HD) wallets", seealso="wallets")))The most commonly used derivation method uses a tree-like structure and is known as a _hierarchical deterministic_ or _HD_ wallet.
Deterministic wallets are initialized from a seed. To make these easier to use, seeds are encoded as english words, also known as _mnemonic code words_.

The next few sections introduce each of these technologies at a high level.
