Opening Keynote Day 1: Trust
summary
Argues trust is unavoidable and defines it precisely as a conscious decision to take risk on a known person for a limited benefit; presents a reusable model — R-cycle: reward, analyze, decision, risk — mapped to OODA. Shows failures: PGP’s web-of-trust fragmented by inconsistent identity rules, PKI collapsed into “certificate manufacturing” due to liability, and blockchain’s “less trust” claim is misguided. Cites successes: a 5,000-assurer CoCERT model plus arbitration, early Facebook identity UX, and human limits like Dunbar's number (≈150) shaping viable group-based trust solutions.
