These + * are sets of keys that have not yet been used to provide addresses or receive + * change. + * + * The Bitcoin Core wallet was originally a collection of unrelated private + * keys with their associated addresses. If a non-HD wallet generated a + * key/address, gave that address out and then restored a backup from before + * that key's generation, then any funds sent to that address would be + * lost definitively. + * + * The keypool was implemented to avoid this scenario (commit: 10384941). The + * wallet would generate a set of keys (100 by default). When a new public key + * was required, either to give out as an address or to use in a change output, + * it would be drawn from the keypool. The keypool would then be topped up to + * maintain 100 keys. This ensured that as long as the wallet hadn't used more + * than 100 keys since the previous backup, all funds would be safe, since a + * restored wallet would be able to scan for all owned addresses. + * + * A keypool also allowed encrypted wallets to give out addresses without + * having to be decrypted to generate a new private key. + * + * With the introduction of HD wallets (commit: f1902510), the keypool + * essentially became an address look-ahead pool. Restoring old backups can no + * longer definitively lose funds as long as the addresses used were from the + * wallet's HD seed (since all private keys can be rederived from the seed). + * However, if many addresses were used since the backup, then the wallet may + * not know how far ahead in the HD chain to look for its addresses. The + * keypool is used to implement a 'gap limit'. The keypool maintains a set of + * keys (by default 1000) ahead of the last used key and scans for the + * addresses of those keys. This avoids the risk of not seeing transactions + * involving the wallet's addresses, or of re-using the same address. + * + * The HD-split wallet feature added a second keypool (commit: 02592f4c). There + * is an external keypool (for addresses to hand out) and an internal keypool + * (for change addresses). + * + * Keypool keys are stored in the wallet/keystore's keymap. The keypool data is + * stored as sets of indexes in the wallet (setInternalKeyPool, + * setExternalKeyPool and set_pre_split_keypool), and a map from the key to the + * index (m_pool_key_to_index).
