e/acc, techno-optimism, and the case against governing through fear.

COLDCARD, BTCPay Server, and Liquid failed at different layers. Together they show why Bitcoin security must cover entropy, credentials, software boundaries, bridges, and operations.

The 2026 COLDCARD incident did not defeat the air gap. It exposed a different boundary: whether the shipped firmware generated a seed with the entropy users expected.

A careful look at the September 2026 Liquid incident, what was reported, what remains unknown, and why sidechain peg security is distinct from Bitcoin consensus.

Coinkite’s entropy incident is a useful correction to AI-security hype: models can expand review capacity, but build boundaries, hidden state, and missing tests still demand deterministic evidence.

When an AI agent can call tools, malicious text can become an execution path. The defense is a real privilege boundary—not a stronger system prompt.

A product engineer’s view of why Conduit uses Nostr and Lightning for portable identity, open product discovery, encrypted orders, and direct payments—and where the hard work remains.

Nostr replaces platform-issued accounts with portable keys—but a signature is an authorization, not just authentication. Good signer UX must make that distinction visible.

Capitulation signals, long-term-holder supply, and a shallower drawdown support a Bitcoin bottom thesis. Here is the evidence, the countercase, and what would prove the thesis wrong.

Bitcoin’s latest cycle had no classic blow-off top and a shallower drawdown. The difference may be lower amplitude and changing market structure—not the end of cycles.
