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 element | topos 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 π | subobject classifier valuation assigning truth-like degree to each object |
| stake / token weight | measure object or probability valuation in the internal logic |
| random walk convergence | sheaf-theoretic colimit or fixed point in the topos of stochastic processes |
| shard / local subgraph | subtopos representing a localized internal logic |
3. data structures
-
indexed category of shards
- each shard (topic, time slice, or geography) is a slice category
C/Xin the topos. - morphisms between shards are geometric morphisms preserving structure.
- enables compositional proofs of focus convergence per shard before global merge.
- each shard (topic, time slice, or geography) is a slice category
-
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.
-
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
-
local reasoning:
each shard computes π over its subgraph in the internal logic of its topos. -
proof generation:
shards produce agds proofs for their updates. -
global merge:
π-values are lifted via inverse image functors to the ambient topos and colimit-combined. -
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
- formalize shard categories and geometric morphisms for focus computation.
- implement sheaf of π-values with exponential decay constraint solver.
- integrate topos-indexed agds proofs into the foculus consensus loop.
- test cross-logic focus merging on simulated heterogeneous graphs.
