TRANSPARENT WORKFLOW
Our Delivery Process: From Archive to Proof
A predictable, security-first process that transforms your archived blockchain data into verifiable, court-ready proofs. We handle the technical complexity so you can focus on your core product.
01
1. Data Source Integration
We establish a secure, read-only connection to your data source—be it an archival node, cloud storage (S3, GCS), or a custom database. Our systems perform integrity checks to ensure data lineage is preserved from the start.

Frequently Asked Questions
Get clear answers on how we deliver secure, verifiable proofs for your archived blockchain data.
A standard implementation for a single chain takes 2-3 weeks, from initial architecture to production-ready API endpoints. Complex multi-chain integrations or custom verification logic can extend this to 4-6 weeks. We provide a detailed project plan with weekly milestones during the scoping phase.
