Message-layer focus
Identify the messages that need to move between institutions — for example in finance, health or infrastructure — and clarify how they should be interpreted by participating systems so that they can be exchanged reliably.
Domains & Pillars
Civilizational domains, treated at the message layer only.
Interlayer aligns with the same broad pillars used in global interoperability work, but remains narrowly focused on message definitions, flows and assurance — not on policy-setting, supervision or governance.
Finance & economy
Public-interest systems
Infrastructure & services
Culture & civil society
Work is scoped so that interoperability patterns can support multi-pillar programmes without introducing a new platform owner or centralising operational control.
How the pillars are used
A way to organise message flows, not a new governance layer.
The pillars provide a shared map of where messages originate and where they need to land. Interlayer works inside that map at the translation layer only, leaving mandates, rules and decision-making with existing institutions and programmes.
Cross-pillar flows
Many programmes cross multiple domains (for example employment, education and social protection). Pillars help keep the message flows structured and transparent, even when responsibilities and governance arrangements differ.
Governance boundaries
Governance, policy and funding remain with institutions, regulators and programmes. Interlayer concentrates on neutral interoperability support under those decisions, without taking custody of records or exercising authority over participants.
Pillar overview
Twelve pillars, common message themes.
Each pillar represents a domain where interoperability questions arise. A consistent message-layer approach is applied within each, subject to local governance and legal frameworks, without imposing a new platform or operating model.

Cross-pillar examples
Programmes that span multiple domains.
Real programmes often require signals to move across finance, labour, education and other domains. The message-layer approach is designed to support that complexity while remaining tightly scoped and non-custodial.
Example 1
Cross-border employment support
Coordination between labour, finance and social protection systems to support workers across borders, without creating a new central platform or altering institutional mandates.
Example 2
Public-interest infrastructure programme
Signals between finance, energy, transportation and oversight domains for a shared infrastructure initiative with multiple operators, where each party retains its own systems and responsibilities.
Example 3
Health, identity & social support
Structured messaging between health, identity and social protection systems where privacy, continuity and clear institutional boundaries are critical.
Next step
Discuss a specific domain or cross-pillar programme.
If you need to understand how this message-layer approach might apply across one or more pillars — for example finance and labour, or health and social protection — you can initiate a controlled, non-promotional discussion.
