CasperLabs is developing a fully decentralized, scalable, public blockchain designed for mass enterprise, developer, and consumer adoption. The team lead by CasperLabs CEO Medha Parlikar and Lead Casper Developer Michael Birch is developing a new open source blockchain project.

The protocol uses CBC-Casper, a Correct by Construction, Proof of Stake consensus protocol that uses bonds and slashing (penalties) to secure the network. CasperLabs is sponsoring research done by top blockchain researcher, Vlad Zamfir, who is the Lead Architect of CBC Casper.

Releases of the CasperLabs node software can be found on GitHub at

Full Decentralization

High performance is achieved without compromising on decentralization of the network or resorting to off-chain settlement.

CBC Casper Proof-of-Stake

In development for many years, Correct-by-Construction Casper Proof-of-Stake consensus provides faster, safer and more energy and computationally efficient decentralized network consensus.

Concurrent, Secure Execution

Blocks are proposed and propagated concurrently. Smart Contracts execute concurrently rather than serialy on an multi-threaded, formally verified execution engine.


Superior throughput is achieved through a more efficient consensus protocol and system-wide concurrent execution.

Heterogeneous Side Chains

One size doesn’t fit all in the real world, why should a Blockchain? Spin up side chains with custom economic and performance configurations.

Open and Developer Friendly

Develop Smart Contracts in any programming language that compiles to WASM.
