Blockhouse :Technology with trust built in

High security • Pro‑regulation • Environmentally friendly


Our founders Bill Roscoe and Bangdao Chen originally worked together at Oxford University, and later set up Chieftin Lab in Shenzhen, China. This effort helped them to raise funds to found TBTL and the University College Oxford Blockchain Research Centre.

Major investment from SSC based in Hainan, China, broadened our focus to support the development of the Digital Civilisation initiative emerging from Hainan and its new free trade area, identified as the focus of Chinese blockchain development.

SSC and its OxHainan research centre in Hainan are our close partners in the Digital Civilisation Initiative. Chieftin is working to promote our technology and products, and collaborating with other Chinese companies such as Ping An and IBR.

We continue to sponsor the University College Oxford Blockchain Research Centre.

Our collaboration with IBR recently won the 4th (Chinese) national blockchain competition. Please use the link below to view the article.

Who We Are

Innovators of Blockchain Security Technology, Trusted by Design.

We are scientists and engineers creating new security solutions for today’s complex and decentralised world. We are inspired by the integrity of blockchain and the need to integrate it with privacy and regulation.

We believe in the power of technology to harness trust and create a better world.

Out of the collective good of humanity and the predictable logic of IT, both protected by leading edge cryptography, we build solutions that secure yet free your data.

We provide solutions that form the core of banking, e-government and identity systems, with integrated regulation.

We believe that as technology and society develop, the security technology that supports them needs to be renewed. That is what we are doing, in particular making decentralised systems secure.
