PROOFLINE
Any app can read the credit file. Only verified proofs can change it.
Verified economic events on Ethereum become persistent credit state on Creditcoin that separate applications can consume.
No wallet. No signing. No state changes. Figures are read from Creditcoin as this page draws them.
Verified history is the input. CreditFile is the state. Applications are the consumers.
getCreditFile() getCreditEvents() getTerms()Not a score. A score compresses history into one number; CreditFile keeps the history, its counters and the earned terms, and each application derives its own answer. No application can write to it, so none can rewrite the history another one reads.

Borrower state
TRUSTED, 80% advance, 12% APR, under ProofLine policy v1. Earned from verified history (CreditFile): capacity $9,600, approved line $9,600. Current consumer state (Treasury): available $6,440.04, debt $3,159.96.
5 settlements verified through Attestcoin, 3 registered counterparties, 100% on time, largest settlement $12,000. The counterparties are not shown to be economically independent: this demonstration history was seeded by the builder.

Verified, and not established
Verified: source transaction inclusion; source receipt succeeded; expected event emitted; event from the authorized source; replay identity unused; credit event persisted to CreditFile; credit terms derived deterministically from that state.
Not established: counterparties are economically independent; the demonstration history represents external commercial activity; CreditFile guarantees repayment; tier thresholds are Creditcoin protocol standards; every late payment has already been reported: the file shows one only after it is proven.
ProofLine verifies evidence. It does not manufacture trust outside that evidence.
