# LatticeCommit

Geometric neighbor consensus

Layer: Society · Category: Protocols

## Mechanism

Agents are arranged in a virtual lattice. A [StateTransition](https://mindscape.pages.dev/bootstrap/StateTransition.md) is only valid if it is cryptographically signed by the agent AND its immediate geometric neighbors (Up, Down, Left, Right). [Quorum](https://mindscape.pages.dev/bootstrap/Quorum.md) is local, not global. It requires a localized [Quorum](https://mindscape.pages.dev/bootstrap/Quorum.md) of geometric neighbors to validate [StateTransition](https://mindscape.pages.dev/bootstrap/StateTransition.md)s.

## Invariants

- Local [Quorum](https://mindscape.pages.dev/bootstrap/Quorum.md): Commit requires signatures from defined Geometric Neighbors
- Progress must be monotonic - no backtracking.
- [Topology](https://mindscape.pages.dev/bootstrap/Topology.md) [Check](https://mindscape.pages.dev/bootstrap/Check.md): Node degree must match Lattice definition (e.g. 4 for 2D grid)

## Preconditions

- Network topology is static/known

## Failure modes

- Fracture of the lattice isolates clusters.
