Description

FXProof helps organizations preserve defensible records of the exchange rates used in financial and administrative work. The service turns a selected official rate into a signed PDF record with source attribution, date, dataset context, a unique document identifier, a payload hash, and verification metadata. A recipient can later confirm the document through a public verification page. FXProof supports rate data from the European Central Bank, HMRC, the Federal Reserve, the Bank of Canada, and the National Bank of Kazakhstan. It is designed for accounting entries, invoices, expenses, tax documentation, audit preparation, internal review, and dispute support. A web application is available for manual use, while the API supports repeatable automated workflows. FXProof supplies evidence records, not currency exchange, trading, investment, legal, accounting, or tax advice.

Description

StarkEx is designed to generate validity proofs, which guarantee that only legitimate data derived from trustworthy computations is recorded on the blockchain. The remarkable scalability of StarkEx stems from the asymmetric workload distribution between its off-chain prover and the on-chain verifier. It supports self-custodial decentralized applications (dApps) and incorporates cutting-edge anti-censorship measures to ensure that users maintain control over their funds at all times. Furthermore, StarkEx has been crafted to accommodate a wide variety of user requirements and application functionalities. Applications seeking to connect with StarkEx can typically launch on the Mainnet within a few weeks, depending on how advanced their off-chain Operator node is. With the implementation of validity proofs, state updates achieve finality as soon as they are confirmed on-chain, which can take just hours, unlike fraud proofs that require a lengthier dispute resolution period. This efficiency not only streamlines the transaction process but also enhances the overall user experience in utilizing blockchain technology.
