ProofLink: The Cryptographic Receipt Layer No Competitor Has
Every autonomous IT action leaves evidence. ProofLink makes that evidence immutable, verifiable, and compliance-ready — without any manual effort from your team.
What Is ProofLink?
ProofLink is iTechSmart's immutable receipt engine. Every autonomous action the platform takes — a pod restart, a firewall rule change, a configuration update — produces a SHA-256 hashed receipt with timestamp, actor, action, and outcome. Unlike logs, which can be deleted or altered by any privileged user, receipts are write-once.
The result is a cryptographic chain of evidence that answers the compliance question auditors actually ask. See it live at the ProofLink proof portal.
Why Logs Fail Compliance Auditors
Logs are mutable, distributed, and tool-dependent. In a typical enterprise environment, an incident generates entries across SIEM, APM, cloud provider audit logs, application logs, and network flow logs — each in a different format, each owned by a different team. Reconstructing a complete timeline from eight different log sources takes days and requires specialist knowledge of each system.
ProofLink generates a unified chain in milliseconds. Every action is a single receipt. Every receipt links to its predecessor via parent_hash. The chain is complete by the time the action finishes executing — no reconstruction required. This is what separates UAIO from every other autonomous IT approach on the market.
The ProofLink Receipt Schema
Each ProofLink receipt contains eight fields: chain_id (unique identifier for the incident chain), actor (service account or agent ID), action_type (categorized action class), target (the affected resource), outcome (success/failure with detail), timestamp (synchronized clock, UTC), hash (SHA-256 of the full payload), and parent_hash (SHA-256 of the preceding receipt).
Chained receipts are tamper-evident by design. Any alteration to any receipt field produces a different SHA-256 hash, which breaks the chain at that point. Explore the ProofLink entity for the full schema reference.
Compliance Frameworks ProofLink Satisfies
ProofLink was designed to satisfy the audit evidence requirements of the four frameworks that matter most to enterprise IT:
SOC 2 CC6/CC7
Requires evidence of logical access controls and anomaly detection. ProofLink receipts prove every access event and remediation action with actor identity and policy version.
HIPAA § 164.312(b)
Requires mechanisms to record and examine activity. ProofLink receipts satisfy the record requirement; the hash chain makes tampering detectable.
FedRAMP AU-2/AU-3
Requires event logging with sufficient detail for post-incident forensics. ProofLink eight-field schema exceeds AU-3 content requirements.
PCI-DSS 10.x
Requires audit log protection from modification. ProofLink write-once architecture and hash chain provide structural protection.
The full iTechSmart suite is built on ProofLink as its evidence foundation.
