On Self Custody & Entropy – 13 Aug 2026

RRBTCAugust 13, 2026Meetup Presentations, Monthly Meetups

Discussion around self-custody and entropy led by Brian: Self custody is a series of tradeoffs, and July 30 was an expensive reminder of that. A random number generator flaw in a widely owned device drained bitcoin from numerous wallets, using a bug that had been public since 2021. We will start there, then work outward to the questions it raises. How do you evaluate a hardware wallet when the thing that failed was visible from the outside but overlooked by many? What actually separates one vendor from another, and how much of that difference is real? And if you decide to run your own multisig, what are you signing up for in exchange for the redundancy? This will be a practical discussion around custody for Bitcoin so you can better evaluate which factors are most important to you. Stop on by Round Rock Bitcoiners #50 and learn, grow, and network with your local bitcoin community.
