Measuring consensus about consensus — sybil-resistant, verifiable straw polls on Bitcoin soft-fork proposals. Built on Archon DIDs for the bitcoin++ Toronto 2026 (Consensus Edition) hackathon.

One attendee → one DID + attendee credential → one encrypted, auditable ballot. Results are revealed in an organizer ceremony and anchored to BTC:signet.

Honest scope note: the one-ballot-per-credential rule is enforced by the protocol, but credential issuance in this build is open (pick a handle, get a credential). Binding issuance to a conference badge scan is the intended deployment policy — TBD.

Live demo (during the event): https://hal.tailc9fdf.ts.net — served from the hackathon laptop via tailscale funnel --bg 3210; keys never leave the machine.

Run it

Requires Node 22.15.x (the wallet crypto needs modern WebCrypto — older Node fails with a getRandomValues error).

npm install
ARCHON_PASSPHRASE=<your-wallet-passphrase> PORT=3210 npm start

On first start the server creates/uses the organizer wallet (./wallet.json), then seeds the attendee credential schema and four polls (CTV, CSFS, CTV+CSFS, status-quo) on the Archon registry. State lives in data/ — wipe it to reseed fresh polls.
