package org.bitcoinj.store

Block stores persist blockchain data downloaded from remote peers. There is an SPV block store which preserves a ring buffer of headers on disk and is suitable for lightweight user wallets, a store that's backed by Postgres and which can calculate a full indexed UTXO set (i.e. it can query address balances), a store that's backed by the embedded H2 database, and a memory only store useful for unit tests.
