Permissioned Blockchain Architecture
Private and consortium networks built on established permissioned-blockchain platforms — with governance, access control and the right consensus model for the job.
Swiss software architecture & engineering
Fintech and permissioned blockchain infrastructure, built for production.
We help companies worldwide design and run secure systems for digital assets, trade finance, settlement and auditability.

The problem
Most companies don't need blockchain hype. They need reliable coordination.
The hard part is rarely the ledger — it's keeping settlement, custody, identity and coordination cleanly separated, so each can be governed, secured and audited on its own terms.
Use the right layer for the right job
01
Settlement
How value moves and finalises.
02
Custody
How keys and assets are held.
03
Identity
Who participants are, and what they may do.
04
Coordination
How the workflow is agreed and recorded.
Services
From architecture to production operations.
The full stack a multi-party system needs — from the first architecture decision to running it in production.
Fintech & Digital Asset Infrastructure
Payment flows, tokenised claims, reconciliation and audit trails — on event-driven systems that have to balance correctly, every time.
Payment Settlement Integration
Settlement wired into your workflows via monitored deposits, transaction proofs and custody — over a public network, a private one, or a bank webhook. Money stays cleanly separate from coordination.
Trade Finance Workflow Automation
Obligations, financing and settlement modelled across counterparties, with selective visibility and a defensible audit trail. Automate the steps that still wait on manual approvals.
Identity, Permissions & Auditability
KYC/KYB-aware onboarding, role-based access and certificate-based identity (membership services, certificate authorities), with traceability and selective disclosure where it matters.
Cloud & Production Infrastructure
Kubernetes, Terraform and AWS: CI/CD, secure deployments, monitoring, HA, private networking. The work that decides whether a system survives real operations.
Where our work fits best:
- Tokenised payment obligations
- Receivables financing
- Supplier financing
- Commodity trade workflows
- Public-network settlement flows
- Private consortium networks
- KYC/KYB-aware onboarding
- Audit-ready transaction workflows
Approach
Architecture first, then build for production.
A phased path that cuts technical risk early and keeps concept-to-pilot short.
- 01
Understand the business workflow
Start from how the business actually works: the parties, obligations, approvals and who sees what.
- 02
Separate the layers
Split settlement, custody, identity and coordination so each is governed on its own terms.
- 03
Choose the right architecture
Decide what fits — a permissioned network, a public settlement layer, plain backends, or a mix — and why.
- 04
Build a pilot
A focused pilot that proves the critical paths end to end. No over-building.
- 05
Harden for production
Add the security, monitoring, HA and controls a real deployment needs.
- 06
Operate and iterate
Run it reliably, and grow it as participants and volumes do.
Technologies
A focused, dependable toolset.
Proven technologies, applied where they fit. The architecture picks the tools — not the reverse.

Why NeferByte
Calm, practical engineering for systems that have to be right.
An architecture-first mindset, with hands-on experience across permissioned systems, fintech, backends and cloud.
Architecture-first
We design before we code, so the structure holds as it grows.
Permissioned systems experience
Hands-on with permissioned-blockchain platforms, consensus models and consortium governance.
Fintech constraints understood
Compliance, auditability and privacy designed in from the start.
Operational reliability
The infrastructure and operations that keep a system running under real load.
Bridges the whole stack
Across blockchain, backend and cloud — so the pieces fit instead of colliding.
No noise
Clear engineering. No exaggerated promises, no theatre.
