Garantice

Garantice is a theoretical framework and protocol for providing auditable guarantees in digital services. It combines formal verification methods with cryptographic attestations to certify that a system meets predefined guarantees, such as uptime, data integrity, or privacy compliance.

The term emerged in academic and industry discussions in the 2020s as a shorthand for guaranteed attestations in cloud and software ecosystems. It is used to describe a structured approach to translating contractual guarantees into machine-verifiable evidence.

Mechanism: A garantice contract specifies commitments (for example, availability targets, latency bounds, or data-handling rules). System components generate attestations that are cryptographically signed and posted to a trusted registry or distributed ledger. A policy engine interprets these attestations and computes a compliance verdict, which can be used for billing, auditing, or risk assessment.

Applications: guaranteed service levels in cloud computing, cross-border data processing, critical infrastructure monitoring, and procurement of software services where verifiable compliance is important.

Limitations and criticism: The approach adds operational and computational overhead, relies on trusted attestations, and may raise privacy concerns. Interoperability among providers and standards fragmentation can hinder adoption.
