| Package | Description |
|---|---|
| org.bitcoinj.core |
The core package contains classes for network messages like
Block and
Transaction, peer connectivity via PeerGroup,
block chain management and the Wallet class. |
| org.bitcoinj.jni | |
| org.bitcoinj.script |
Classes for working with and executing Bitcoin script programs, as embedded in inputs and outputs.
|
| org.bitcoinj.signers |
Transaction signers know how to calculate signatures over transactions in different contexts, for example, using
local private keys or fetching them from remote servers.
|
| org.bitcoinj.wallet |
Classes that support the
Wallet, which knows how to find and save transactions relevant to
a set of keys or scripts, calculate balances, and spend money: the wallet has many features and can be extended
in various ways, please refer to the website for documentation on how to use it. |
