marrying topos theory and focus flow computation

1. philosophical and mathematical motivation

  • topos theory gives a unifying categorical framework where different “universes of discourse” (contexts, logics, or worlds) are formalized as categories with internal logic.
  • focus flow computation (ffc), as defined in the collective focus theorem (cft) architecture, models attention dynamics on a token-weighted, authenticated, and cryptographically verifiable knowledge graph.
  • the intersection: a topos can serve as the semantic layer for the evolving focus graph, where each object is a “bundle” of possible states/interpretations, and morphisms are focus-preserving transformations.
  • this allows cft/ffc to reason internally in different logical universes while still preserving external consistency.

2. mapping core cft/ffc entities into a topos

cft/ffc elementtopos interpretation
particle (content-addressed node)object in the topos representing a proposition/data type
cyberlink (weighted directed edge)morphism in the topos with extra structure for weight and endorsement
focus vector πsubobject classifier valuation assigning truth-like degree to each object
stake / token weightmeasure object or probability valuation in the internal logic
random walk convergencesheaf-theoretic colimit or fixed point in the topos of stochastic processes
shard / local subgraphsubtopos representing a localized internal logic

3. data structures

  1. indexed category of shards

    • each shard (topic, time slice, or geography) is a slice category C/X in the topos.
    • morphisms between shards are geometric morphisms preserving structure.
    • enables compositional proofs of focus convergence per shard before global merge.
  2. sheaf of attention weights

    • assigns to each open set (context) a vector space of π-values with exponential optimality constraints.
    • gluing conditions ensure global π is consistent with all local computations.
  3. internal probabilistic monad

    • captures stochastic transitions in the internal logic of the topos.
    • implements token-weighted markov chains with authenticated graph proofs.

4. algorithms

4.1 topos-aware power iteration

  • run π updates internally in each subtopos, using local cyberlinks + authenticated proofs.
  • use inverse image functors of geometric morphisms to pull local π to the global stage.
  • global π = colimit of local π vectors, merged via categorical limits to preserve safety invariants.

4.2 focus-preserving morphism pruning

  • identify morphisms (cyberlinks) whose removal changes π below a tolerance.
  • apply subobject classifier logic to detect logically redundant or inconsistent links.

4.3 attention sheaf optimization

  • solve for π that maximizes entropy subject to exponential decay constraints across ranks.
  • ensure solutions are global sections of the sheaf of attention weights.

5. security and verification

  • authenticated graph data structures (agds) ensure that any topos morphism corresponding to a cyberlink can be verified externally.
  • privacy-preserving commitments (pedersen, poseidon2) keep the topos’ internal state consistent but hidden unless disclosed.
  • categorical pullback diagrams model selective disclosure policies without breaking global consistency.

6. example computation flow

  1. local reasoning:
    each shard computes π over its subgraph in the internal logic of its topos.

  2. proof generation:
    shards produce agds proofs for their updates.

  3. global merge:
    π-values are lifted via inverse image functors to the ambient topos and colimit-combined.

  4. reward distribution:
    Δπ changes are converted to token rewards per the π-minting theorem.


7. benefits of the merge

  • logical pluralism: different shards can operate under different internal logics (intuitionistic, probabilistic, quantum) without breaking global coherence.
  • formal verifiability: topos morphisms + agds proofs guarantee end-to-end correctness.
  • resilience: categorical structure isolates local faults while preserving global safety theorems.
  • semantic scalability: enables context-aware computation at planetary scale.

8. next steps

  1. formalize shard categories and geometric morphisms for focus computation.
  2. implement sheaf of π-values with exponential decay constraint solver.
  3. integrate topos-indexed agds proofs into the foculus consensus loop.
  4. test cross-logic focus merging on simulated heterogeneous graphs.
