Blockchain Architecture & Trust Layer

Transparency, Security, and Scalability for the Enterprise

To guarantee the immutability of the logs (Audit Trail) generated by our Artificial Intelligence and provide legal value (eIDAS 2.0) to documents, we adopt a clear and scalable enterprise Blockchain architecture. We have moved past the generic public-blockchain approach to define a precise operational protocol that meets the privacy, compliance, and budget needs of B2B companies.

1. Polygon: The Layer 2 for Operational Speed

We use Polygon as the execution layer for operations that require high frequency, minimal costs, and sub-second confirmation, while keeping compatibility with the EVM ecosystem.

  • ✓Why Polygon: High throughput (up to 65,000 TPS) with near-zero transaction costs, ideal for massive notarizations of audit trails and digital signatures.
  • ✓Usage: Registration of the document's cryptographic hash (SHA-256) on an Ethereum-compatible layer. No clear or sensitive data is ever exposed publicly.
  • ✓Enterprise Advantage: Extremely low operational costs, fast confirmation, EVM smart-contract compatibility, and a secure bridge to mainnet.

2. Hyperledger Fabric: The Notarization Standard (Default)

We use Hyperledger Fabric as the default infrastructure for all notarization operations (e.g., digital signatures in SignSiSure and Audit Trails in ZenTratto).

  • ✓Why Hyperledger Fabric: Permissioned enterprise blockchain with cryptographic security, deterministic finality, near-instant confirmation, and full EU data residency.
  • ✓Usage: Registration of the document's cryptographic hash (SHA-256) on a permissioned ledger. No clear or sensitive data is ever exposed publicly.
  • ✓Enterprise Advantage: Predictable costs (no transaction fees), full regulatory compliance (GDPR, eIDAS 2.0), and absolute control over who participates in consensus.

Our enterprise architecture allows us to adapt to any business need: from notarizing critical business documents (Hyperledger Fabric) to managing consortium-wide audit ecosystems with cryptographic privacy guarantees. Always with an obsessive focus on privacy and compliance with European regulations.
