Framework Implementation Maturity in Blockchain-Based Third-Party Compliance Assessment

2026-07-27

AI Summary

Traditional compliance assessments rely on point-in-time audits and self-attestation, which struggle to enable continuous, cross-organizational, and traceable verification of security controls in multi-vendor environments. This work proposes a permissioned blockchain-based Third-Party Risk Assessment (TPRA) framework that transforms static compliance into a dynamic, repeatable, and verifiable continuous governance mechanism through smart contract–automated evaluation workflows, multi-party governance protocols, and longitudinal state tracking. The study contributes an actionable TPRA architecture, along with complementary compliance maturity metrics and a qualitative model, enabling quantification and long-term validation of security control implementation maturity across organizational boundaries and time periods.

Abstract

Cybersecurity and privacy frameworks such as NIST SP~800--53, ISO/IEC~27001, GDPR, and HIPAA are widely used to guide organizational security posture and regulatory compliance. In practice, however, framework adoption is often assessed through point-in-time audits, self-attestations, and fragmented evidence reviews, providing limited assurance that controls are consistently implemented, independently validated, and sustained over time, particularly in environments that rely on third-party vendors. These limitations are amplified in multi-vendor ecosystems, such as healthcare remote patient monitoring (RPM), where compliance obligations span organizational boundaries and assessments are conducted by multiple independent assessors. This paper investigates how permissioned blockchain systems can support framework implementation maturity measurement rather than static compliance verification. We propose a blockchain-based Third-Party Risk Assessment (TPRA) framework that operationalizes assessment workflows, enforces multi-party governance, and preserves longitudinal assessment state using programmable smart contracts. Building on this framework, we introduce a set of evaluation metrics and a qualitative maturity model designed to assess whether compliance controls are verifiably implemented, governed, and sustained across repeated assessment cycles.
