Platform

A unified intelligence stack

PSIONHQ is built as a layered platform — from encrypted compute at the bottom to developer APIs at the top.

Architecture overview

Five layers, one coherent platform

Every PSIONHQ product maps to a discrete layer of the stack. They can be used independently, but the real power emerges when you compose them — AI inference that reads from the vault, credentials that gate wallet access, all surfaced through a unified API.

  • Encrypted compute foundation
  • Zero-knowledge storage above it
  • Portable identity layer
  • Self-custodied digital assets
  • Unified developer API surface

Stack layers

What each layer does

01

Encrypted Compute

Trusted execution environments, secure enclaves, and hardware attestation form the foundation. Every workload runs isolated and verifiable, so no operator — including us — can inspect your data in transit or at rest.

02

Sovereign Storage

Zero-knowledge vaults and hardware-backed key management sit above compute. Documents, secrets, and model weights are encrypted client-side before they ever leave your device.

03

Identity & Credentials

Decentralised identifiers and verifiable credentials give every user and service a portable, privacy-preserving identity layer with selective disclosure and no central authority.

04

Digital Assets & Wallet

A non-custodial wallet layer lets users hold, transfer, and manage digital assets and credentials from one interface — with programmable permissions enforced cryptographically.

05

Developer APIs

REST endpoints, typed SDKs, event streams, and webhooks expose the entire stack to your applications — so you can build on sovereign infrastructure without managing any of it directly.
