The BSV blockchain team are happy to announce the release of three exciting open-source projects as part of their LiteClient Toolbox programme.
BitcoinJ-SV – v1.0.1 Release
BitcoinJ-SV is a highly optimised and lightweight version of the legacy BitcoinJ library that has been tuned for use on the massively scalable original Bitcoin (BSV) blockchain. This is a Community Edition (CE) release, with an Enterprise Edition being planned.
Main features
- Domain, serialization, hashing, merkle proofs and cryptography classes
- Storage functionality for headers/ transactions
- An in-memory block store maintains a full block header history
- Refactoring of some legacy BitcoinJ code

BSV Java Components Library (JCL) – v1.0.5 Release
The BSV Components Library is a suite of Java libraries providing the services required by Java developers who wish to write Bitcoin-based applications.
Combining the various libraries components provides a high-speed toolkit for handling the large transaction volumes we witness on the original Bitcoin (BSV) network.
Main features
- Base library
- Provides representative base classes including Transactions and Blocks, and facilitates the management of their Serialization
- Network library
- Provides connection and streaming capabilities
- Allows applications to connect to and ‘listen’ for incoming blockchain network messages
- Supports commonly used “send/ broadcast” message operations.
- Persistence library
- Operations to save or retrieve blockchain information to and from a database/ repository
- A LevelDB (Key/Value store) reference implementation

Block Headers Client – v1.0.2 Release
The Block Headers Client provides a super-lightweight application that can be used to independently verify block hashes and on the original Bitcoin (BSV) Blockchain. The client can be deployed on the user’s premises via a convenient docker image or built from source.
Main features
- Connects to the BSV network to synchronise block headers
- Whitelists and blacklists internal management
- Maintains a customisable minimum number of peer connections
- A REST API is provided to enable rapid lookups of chain and network state, including:
- Query Chain Tips
- Prune Fork
- Query Headers
- Query Headers State
- Query Network
- Supports BSV Mainnet, Testnet, Regtest and STNnet.
- Additional networks can be added with ease.
Binaries and Source code can be downloaded here:

URL: https://hub.docker.com/repository/docker/bitcoinsv/block-headers-client
Known issues
- Occasionally a race condition can occur, causing a runtime exception since the Headers Client cannot access a level-db database file on the runtime filesystem. If this does occur, simply restarting the headers client resolves the issue. A more graceful preventative measure will be released in a patch-release soon.
- There is a known issue where an unclean shutdown can cause the headers client to fail to read the level-db file store. To fix this issue, delete the level-db database folder, as displayed in the runtime filesystem path in the console log. Once done, restart the Headers Client.
