Zero‑Trust Healthcare Data: Where Blockchain Meets Least‑Privilege Security

Pratik Thantharate is a Principal Software Engineer at ZeroTrustBlock, where he architects and builds the next generation of healthcare data platforms — combining zero‑trust security principles with blockchain’s immutable audit and data integrity guarantees. In an era of escalating healthcare data breaches, his work ensures that every access request to a patient record is continuously authenticated, explicitly authorized, and indelibly logged on‑chain.

With over a decade of engineering leadership in distributed systems, cloud security, and compliance‑heavy environments, Pratik has delivered production‑grade solutions that integrate with major EHR systems while meeting HIPAA, HITRUST, and GDPR requirements. At ZeroTrustBlock, he has pioneered the convergence of micro‑segmented network controls, verifiable credentials, and smart contract‑based access policies — creating healthcare data lakes that are not only interoperable but also tamper‑evident and resilient against insider threats. His approach replaces implicit trust with continuous verification, making blockchain the backbone of a genuinely zero‑trust healthcare ecosystem. At UN Blockchain Week he shares the technical blueprints for securing sensitive health data in a decentralized yet fully compliant manner.
