Innovation That Powers the Future

Previously, Bitcoin Cash

Bitcoin Unlimited previously developed and maintained BCH Unlimited, the official Bitcoin Cash–compatible client. Originally launched as the Bitcoin Unlimited client, it was adapted to support the BCH network, a fork of Bitcoin that occurred on August 1, 2017. Bitcoin Cash delivers on-chain scalability with penny-level transaction fees and fast confirmations, making it a strong fit for global peer-to-peer payments. During our stewardship, BCH Unlimited offered advanced features and optimizations.

Currently, Nexa

Bitcoin Unlimited is actively developing Nexa, our next-generation blockchain client engineered for massive scalability and real-world adoption. Nexa features built-in native token services, enabling the seamless creation and transfer of custom assets without relying on third-party layers. It also integrates smart contract capabilities, empowering developers to build decentralized applications and automate complex transactions directly on-chain. Designed for speed, efficiency, and flexibility, Nexa is built to support high-volume payments, tokenized economies, and enterprise-grade use cases — delivering the infrastructure needed to power the next era of peer-to-peer finance. In many ways, Nexa is Satoshi's original vision realized — a truly scalable peer-to-peer cash network built for the entire planet.

Empowering Every Stakeholder in the Bitcoin Ecosystem

Bitcoin Unlimited empowers users, node operators, miners, and investors, with the tools and voice to shape Bitcoin's evolution.

Users

By supporting Bitcoin Unlimited, you are supporting our organization's efforts to reduce transaction fees and confirmation times by enabling node operators to lift their block size limits, as well as our efforts to reverse the damage done to instant transactions through the misguided replace-by-fee initiative.

Node Operators

The Bitcoin Unlimited client is designed around the principle that Bitcoin should evolve through a bottom-up, free-market-based process where your voice as a node operator can be heard. Using the client's graphical user interface, you can easily adjust your node's block size limit, to signal to miners that you are ready for bigger blocks today.

Miners

With Parallel Validation, your node will no longer be locked up while validating new blocks, but free to do other useful things instead. Bitcoin Unlimited developers are continuously working with progressive miners like you to ensure that the features you need to be successful are included in our software.

Investors

Growing a new digital currency requires committed investors willing to weather the market's volatility. Your support helps ensure that dedication is rewarded. By backing Bitcoin Unlimited, you're advancing our mission to return control of Bitcoin's evolution to the free market.
