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.

Long-term goals include providing documentation and training materials, a weekly newsletter, original research, and facilitating improved relations between businesses and the open source community.

Optech does not exist to make a profit, and all materials and documentation produced are released under the MIT license. We are supported by our generous founding sponsors and contributions from member companies.

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
