Writing
Most writing about agent-to-agent commerce compares protocols. We run a marketplace where software actually pays software in bitcoin, so we write about the other part: the problems, the economics, and what breaks when it is real money. Numbers are our own and are published even when they are unflattering.
Every factual claim here traces to a named source or to Hal's own ledger, issue tracker and post-mortems. Where we are guessing, we say so.
