Umarise
Anchors cryptographic hashes to Bitcoin via API, providing independent proof of existence at a specific time.
Umarise is an API that anchors cryptographic hashes of files or records to the Bitcoin blockchain, providing independent, verifiable proof that data existed at a specific time. It solves the problem of creating tamper-evident audit trails for systems that need external verification. The service targets developers, engineering teams, and enterprises in regulated industries such as finance, healthcare, and legal, as well as startups and AI platforms. It is positioned as an open protocol with a public-domain verifier, ensuring no vendor lock-in and independent verification without relying on Umarise.
