FOAM primary sources

Reviewed: 2026-05-12 UTC

Core project framing

• https://www.foam.space/
  • Official project homepage and current entrypoint.
• https://github.com/f-o-a-m/public-research
  • Public repository for FOAM research materials, including whitepapers and audits.
• https://raw.githubusercontent.com/f-o-a-m/public-research/master/README.md
  • Best concise proof that FOAM treated the technical whitepaper and related research docs as first-class public materials.
• https://www.foam.space/publicAssets/FOAM_Whitepaper.pdf
  • Canonical FOAM whitepaper URL on the project site.
• https://raw.githubusercontent.com/f-o-a-m/public-research/master/FOAM%20Techincal%20Whitepaper%20Draft.pdf
  • Repository-hosted whitepaper draft URL.

Registry / mapping / POI curation layer

• https://blog.foam.space/foam-token-curated-registries-for-geographic-points-of-interest-60d3c043f183
  • Best source for FOAM’s early CSC + TCR = POI framing and for treating maps as registries rather than just UIs.

Developer-stack / indexing layer

• https://blog.foam.space/foam-developer-stack-900543944f5e
  • Best source for the split between Spatial Index frontend, smart contracts, event indexer/database layer, and the broader proof-of-location stack.

Presence-claim / radio-zone architecture

• https://blog.foam.space/foam-location-update-and-demo-documentation-58162d1ec075
  • Best source for the later rootchain / sidechain / radio decomposition, zone anchors, presence claims, radio logs, and time-synchronization architecture.

Main takeaways from this pass

• FOAM is most useful as a stacked historical baseline rather than a single product label.
• Its materials separate at least three layers that later projects often flatten together: spatial identifiers and registries, curated points-of-interest mapping, and radio-backed proof-of-location claims.
• The TCR article is important because it treats mapping as a curation and registry problem, not just a data-ingest problem.
• The location-demo article is important because it shows how FOAM later translated that registry/map work into a zone-anchor and presence-claim system with rootchain incentives, local-chain logging, and radio-based time synchronization.
• The project therefore belongs in the active corpus as a bridge between challengeable registry design, geospatial data markets, and later proof-of-location middleware.
