Everyone deserves the Freedom to Transact—a fundamental right supporting housing, travel, expression, and property. This principle underpins all other civil and human rights. I’m urging its recognition in law, globally. Article:

Courts shouldn’t compel private key disclosure—keys ≠ assets. I helped pass WY’s 2023-HB0086 to protect against this risk. Now pushing for broader adoption in other states & federally. Article:

I will be at the Bitcoin Policy Summit @btcpolicyorg on Wednesday in DC. I am advocating for expanding the ban on compelled private key disclosure beyond Wyoming; the “right to transact”; and supporting decentralized identity digital privacy. I’m available to schedule meetings.

Sign up for our Gordian Developer Meetings too, as we'll likely discuss fair witnessing at a future meeting. (They're the first Wednesday of most months. Today at 10am PT we're discussing provenance marks.) [10/11]

Even if the intent of Verifiable Credentials were better understood, the confusion reveals a gap in their current usage. We need context, and we need to be able to keep that context private until it's needed. [8/11].

Gordian Envelope Elision allows a fair witness to release information over time, to release information to certain people, or to release just a proof of information. [7/11].

Blockchain Commons has a solution for this: Gordian Envelope. It's a way to elide information while maintaining signatures and still being to prove the information exists. [6/11]

The major issue with making Fair Witnessing a reality is privacy. Context can offer a LOT of information, and you don't necessarily want to release it all to everyone. [5/11].

But a Fair Witness statement also needs to hold context. Who is the witness? What is their expertise? What are their unconscious biases? These are required so that when the Witness signs a statements, others can decide what it means. [4/11].

Fair Witnessing is an idea from Robert Heinlein's Stranger in a Strange Land. It says that statements should be precise and unbiased, which is a simple enough start. [3/11]
