The Bitcoin Operations Technology Group (Optech) works to bring the best open source technologies and techniques to Bitcoin-using businesses in order to lower costs and improve customer experiences.

An initial focus for the group is working with its member organizations to reduce transaction sizes and minimize the effect of subsequent transaction fee increases. We provide workshops, documentation, weekly newsletters, original research, case studies and announcements, and help facilitate improved relations between businesses and the open source community.

If you’re an engineer or manager at a Bitcoin company or an open source contributor and you’d like to be a part of this, please contact us at


Optech does not exist to make a profit, and all materials and documentation produced are released under the MIT license.

Seed funding was provided by Wences Casares and John Pfeffer to cover outside contractors and incidental expenses. Resources are provided by Chaincode Labs to support Optech.

Our generous member companies pay an annual contribution to cover expenses.
