PHAZOR – an enterprise SaaS platform

Client background

A regulated organization sought to internalize digital asset management via a private blockchain, replicating the strict governance, compliance, and multi-party approvals already in place for its conventional financial activities – while eliminating all dependencies on public networks, third-party custodians, gas costs, and single points of failure.

Business challenge

The project required strict data isolation and high-end security, with a multi-tenant setup, to ensure no leakage between organizations. Implementing complex organizational multi-party approval rules was technically challenging. Ensuring complete regulatory auditability meant recording all actions on the platform in a tamper-proof manner.

Cost tracking and billing were to be completely transparent, with no need for reconciliation. The system had to be highly responsive, given the slow nature of blockchain confirmations. The system was also required to support custom token operations securely, in a private setting.

Value delivered

We deployed a fully permissioned Hyperledger Besu private blockchain using IBFT2 consensus, delivering zero gas fees, 10-second finality, and total infrastructure ownership. A robust multi-tenant architecture ensured complete data isolation between all organizations.

We integrated the Safe protocol to enable configurable multi-signature wallets with real-time approval tracking and secure on-chain execution. Granular two-layer RBAC (4 roles + 14 permissions) was enforced consistently at both API and UI levels. A tamper-evident audit system logged every action with full context, while an automated billing engine handled per-tenant cost tracking, discounts, partial payments, and PDF invoice generation.
