Proof of Work #33

Aloha from sunny Oahu, and the thirty-third week of this newsletter.

Last week I mentioned that the first exchange for Handshake domains, had developed an open-source chrome extension that allows you to resolve handshake domains right now. This week they have entered private beta for the main exchange, so if you would like to help squash bugs and be among the first people to register decentralized domain names on the Handshake blockchain, you can email tieshun at and ask to get a beta invite.

I’m putting together a small overview of the OTC bitcoin scene in China, which will hopefully run in the next issue. It’s a fascinating world of giant deals being executed on via immature infrastructure, and its a pretty opaque part of the scene. More on that next week!

Lukechampine has corrected the last changes, so the paths are working again ( Also, the old GitHub repository has been archived and the file has been replaced to refer to the link of the new GitLab repo instead (
