Private AWS appliance that issues signed provenance receipts in ~240 ms, giving teams audit-ready evidence bundles for AI, compliance, legal, and decision artifacts.
HX-Provenance is a customer-controlled provenance appliance that turns important digital artifacts into verifiable evidence. Running as a CPU-only VM inside your AWS environment, it issues cryptographically signed provenance receipts and exportable evidence bundles - giving regulated, enterprise, and public-sector teams a repeatable proof path for audit, compliance, legal, cyber, AI governance, and critical decision workflows.
Unlike SaaS provenance services that hold signing keys externally or blockchain-based audit trails with latency and cost trade-offs, HX-Provenance keeps the entire operating boundary - keys, data, and verification logic - under your direct control.
Key Capabilities
Signed Provenance Receipts: Issue ML-DSA-65 (post-quantum) signed receipts for registered artifacts including AI outputs, retrieval results, compliance files, legal packets, cyber incident artifacts, procurement materials, board packets, case files, and other critical decision documents.
Evidence Bundle Export: Package receipts, metadata, and verification material into self-describing evidence bundles for legal handoff, audit review, and chain-of-custody workflows.
Online and Offline Verification: Verify receipts through the appliance API or offline using exported verification material - no always-on connectivity required.
100% Artifact Recall: Every registered artifact is retrievable and verifiable, eliminating gaps in audit trails and chain-of-custody records.
Performance
In benchmark testing, HX-Provenance produced signed verification receipts in approximately 240 ms end to end on a cloud CPU instance, achieving approximately 4.17 receipts per second. This gives teams a fast, repeatable proof path without GPU dependencies.
Storage: Minimum 10 GB boot storage, 100 GB persistent data storage for production.
IAM Permissions: Deploy and operate the VM, manage network and firewall access, access serial console or startup credentials as needed.
Optional AWS Integrations: Write evidence bundles to customer-controlled Amazon S3 buckets. Send telemetry to customer-controlled Amazon CloudWatch.
Network: Customer-managed VPC with security group rules for HTTPS/API access.
Integration Points
HX-Provenance integrates with internal applications, AI/ML pipelines, CI/CD systems, compliance tooling, records systems, and evidence workflows through its REST API. Customers can optionally connect the appliance to Amazon S3 for evidence bundle storage and Amazon CloudWatch for operational telemetry, keeping all data within their AWS account.
Security and Cryptography
Signing Algorithm: ML-DSA-65 (post-quantum digital signature).
Deployment Isolation: Runs entirely within the customer's VPC with no external call-home or key escrow.
Key Control: All signing keys remain under customer control within the appliance.
Data Boundary: Artifacts, receipts, and evidence bundles never leave the customer's AWS environment unless explicitly exported.
Use-Case Scenario
A compliance team at a financial institution uses HX-Provenance to register AI-generated risk assessment reports. Each time the ML pipeline produces an output, the appliance issues a signed receipt binding the report content, model version, input data hash, and timestamp into a verifiable record. When auditors request evidence months later, the team exports an offline-verifiable evidence bundle - proving exactly what the model produced, when, and from what inputs - without relying on the appliance being online at audit time.
Getting Started
To evaluate HX-Provenance, launch the AMI on a supported instance (4 vCPUs, 16 GB RAM minimum), complete initial HTTPS and API key configuration, and issue your first signed receipt. For guided evaluation or pilot deployment planning, contact HolonomiX through the support channel.
HolonomiX is the developer of HX-Provenance, focused on verifiable provenance and evidence integrity for organizations that need to prove what happened across AI, compliance, legal, and decision workflows.
Highlights
100% artifact recall with ML-DSA-65 post-quantum signed receipts issued in approximately 240 ms end to end. Unlike SaaS provenance services that hold signing keys externally, HX-Provenance keeps all keys, data, and verification logic inside your AWS VPC - eliminating third-party key escrow risk and giving you direct control over your entire evidence chain for AI outputs, compliance files, legal packets, and decision artifacts.
Export self-describing evidence bundles containing receipts, metadata, and verification material for legal handoff, audit review, and chain-of-custody workflows. Each bundle is independently verifiable without requiring the appliance to be online - removing the always-on connectivity dependency that limits alternative provenance approaches and enabling air-gapped or delayed audit scenarios.
Deploy as a CPU-only VM (4 vCPUs, 16 GB RAM baseline) inside your existing VPC with optional integration to Amazon S3 for evidence storage and Amazon CloudWatch for telemetry. Achieves approximately 4.17 signed receipts per second with no GPU requirement, giving compliance, legal, AI governance, and security teams a production-ready provenance layer without complex infrastructure dependencies.

HX-Provenance - Verifiable Evidence and Provenance Appliance
You pay by the hour for the compute instance that runs this CPU-only proof and verification service. All three options bill the same way and differ only by instance size. The m7i.large runs on the fewest resources, the m7i.xlarge sits in the middle, and the m7i.2xlarge provides the most CPU and memory. Pick the size that matches your verification and receipt workload. Costs scale with the instance you choose and the number of hours you run it. Larger instances raise the hourly rate but handle more processing.
Top-of-mind questions for buyers
What does the hourly instance charge actually pay for, and what work does the software perform?
You pay per hour for a CPU-only virtual machine that signs and verifies evidence. It issues receipts, checks hash commitments, and applies post-quantum signatures. It does not serve vectors or run a GPU index. Each running instance-hour is billed; the size you pick sets the hourly rate.
Am I charged when the instance is stopped or idle?
Software charges meter running time only. A fully stopped instance stops accruing hourly software charges. Stopped instances may still incur underlying AWS storage fees for their disk volumes. To avoid software charges during idle periods, stop the instance when verification work is not running.
How do the three instance sizes differ in what they can process?
All three run the same CPU-only proof and verification service. The m7i.large has the fewest CPU and memory resources, m7i.xlarge sits in the middle, and m7i.2xlarge carries the most. Larger sizes handle heavier receipt issue, verify, and audit workloads. Pick the size matching your verification volume.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Initial GA release of HX-Provenance. Post-quantum (ML-DSA-65 / FIPS 204) provenance-receipt appliance: issue cryptographically signed receipts, verify online or fully offline, and export self-contained signed evidence bundles. Hardened Ubuntu 24.04 LTS: nginx TLS on :443, IMDSv2 required, root SSH and password auth disabled, CIS sysctl, auditd. Per-instance ML-DSA-65 signing keys are generated on first boot and never leave the instance; no call-home. API keys are minted at first boot and shown once on the serial console.
Additional details
Usage instructions
After launch: 1) Allow TCP 443 (HTTPS API) from your clients and TCP 22 from your admin range in the security group. 2) Retrieve the per-instance admin API key from the EC2 serial console / system log - it's shown once at first boot and never written to disk logs; store it in your secret manager. 3) Health: curl -fsS https://<ip>/health (returns ML-DSA-65). 4) Issue: POST https://<ip>/v1/provenance/exact with Authorization: Bearer <key>. 5) Verify (no auth): POST https://<ip>/v1/provenance/verify. 6) Export a signed evidence bundle: POST https://<ip>/v1/provenance/evidence-bundle, verify it offline with the bundled verifier. SSH admin: ssh ubuntu@<ip> with your EC2 key pair (root/password login disabled). API reference: https://<ip>/docs.
