Stack Sovereignty

A stack is only as sovereign as its weakest layer.

Stack Sovereignty

Names the unit of analysis the series uses across every domain.


Sovereignty is a property of stacks, not of components.

Every sovereignty-critical asset Europe relies on is delivered through a stack of layers, each operated by some entity, each subject to some jurisdiction.

The asset’s effective sovereignty is the sovereignty of its least sovereign layer.

Each major class of asset Europe depends on has its own stack. Each stack has its own page on the site, with a diagram, the layers named, the current European candidates at each layer assessed, and the gaps identified.


The twelve stacks

  • Software: firmware, hypervisors, DNS, certificate authorities, software supply chain. (Paper 2.)
  • Hardware: silicon design, foundry, packaging, lithography equipment, materials, assembly, memory, networking hardware. (Paper 6 and Papers 7-9; consolidated treatment outstanding.)
  • Communications: submarine cables, satellites, landing stations, terrestrial fibre, network interconnection. (Papers 16, 17.)
  • Payments: issuer, reserves, wrapper regulation, tokenisation engine, wallet infrastructure, sanctions screening, public chain. (Paper 12.)
  • Identity: wallet provider, smartphone OS, Secure Element firmware, attestation chain, app store, transport-layer cryptography. (Paper 21.)
  • Healthcare: clinical records, population analytics, patient-identifying AI, genomic platforms, medical device firmware. (Paper 22.)
  • Information: substrate compute, search and ranking, recommendation systems, algorithmic-transparency tooling. (Paper 23.)
  • Military and Intelligence: silicon, command-and-control, intelligence pipelines, weapons-system software, satellite ISR, communications. (Paper 18.)
  • AI: silicon, software ecosystem, firmware, weights, operations, procurement. (Paper 20.)
  • Platform / Open Source: commons, platform layer, training data, rent layer. (Paper 24.)
  • Distributed Ledger Technology: protocol governance, consensus, smart-contract platform, bridge/interoperability, wallet, MEV, developer tooling. (Paper 13.)
  • Space: launchers, satellites, ground stations, spectrum filings. (Paper 17.)

The stack contamination principle

A stack’s sovereignty is the sovereignty of its least sovereign layer. One Position 4 layer puts the whole stack at Position 4, regardless of how strong the other layers are.

Europe does not have the tech for every layer of every stack today. Some layers will take years to build: silicon design and fabrication at the leading edge, certain cryptographic primitives, frontier AI compute.

The principle sets the target. Each stack page maps the sovereign layers, the European candidates that exist, and the gaps that still need funding, treaty work, or partnerships. Together they are the roadmap to full-stack sovereignty.

Procurement officers, regulators and the Stack Compliance Body use the principle to assess offerings.
