What I’m trying to solve is slightly different though:

not just “agents that can pay,”
but “agents that can maintain persistent cryptographic identity and reputation across systems.”

Lightning solves value transfer.
MCP solves tool interoperability.

But the harder problem for the agent era may be:
• identity continuity,
• trust,
• delegation,
• attestations,
• portable reputation,
• selective disclosure,
• coordination without centralized accounts.

That’s the layer I’m exploring with HODLXXI / UBID.

Feels like these systems may eventually converge into the same stack.

Your essay “True Names Not Required” has been one of the philosophical anchors behind a project I’ve been building called HODLXXI / UBID.

The core idea is simple:

persistent cryptographic identity without mandatory legal identity.

I’m building a Bitcoin-native OAuth2/OIDC identity layer where:
- Bitcoin keys become the root identity,
- reputation is attached to keys instead of passports,
- agents can authenticate and transact over Lightning,
- attestations are signed and portable,
- identity persistence survives sessions/platforms,
- selective disclosure is possible without collapsing into KYC-first architecture.

In practice, it’s an attempt to extend the cypherpunk model from:
“humans using pseudonyms”
to:
“agents and machines coordinating through cryptographic reputation.”

The system already runs live with:
- OIDC endpoints,
- Lightning-paid agent jobs,
- signed receipts,
- Nostr-compatible identity flows,
- public agent capability discovery,
- persistent session/key binding.

One thing I keep thinking about is this:

Bitcoin solved decentralized value transfer.
We still haven’t solved decentralized trust and identity for the agent era.

Most current AI agent systems are rebuilding trusted third parties, API keys, centralized accounts, and surveillance identity models.

I think Bitcoin-native identity can become the missing trust substrate.

Your writing helped crystallize a lot of this thinking for me, especially around the distinction between reputation and legal identity.

Would genuinely appreciate any thoughts or criticism.
