Proof of Bitcoin stake for the open web — a sybil-resistance primitive. No custody, no account, no KYC. - OrangeCheck GitHub · github.com
The Bitcoin address you already control is your account. Sign one message to prove it — BIP-322, never a transaction. Six open protocols, three products, one identity. No custody, no token, no issuer. Every artifact verifies offline, forever.
