Exochain develops general legal and cyber liability risk-reducing tokenized blockchain protocols that deliver secure ownership, custody, and care of mission-critical identifying data. Its patent pending Odentity scores unique identifiers such as network, browser, client, biometry, and demonstrated knowledge weighted by the legal jurisdiction of parties' within differing geographies and corpora of law. Exochain API methods are called during login processes and elsewhere to reduce risks by establishing and recording the identity and ownership of data elements. The LYNK Protocol provides a mechanism to ensure permission-based tokenized access to data elements governed by legal terms and conditions for both blockchain smartER-contracts and any overarching governing business terms and conditions, reps, warranties, and restrictions. The signed, sealed, fingerprinted, data processing governance contracts are then recorded to provide evidentiary-quality compliance and enforceability.
