LAGOS: Latency-aware Accountable Governance for Overlay Scaling

LAGOS is a novel research framework designed to address the tripartite challenge of accountability, scaling, and latency in distributed overlay networks. It adopts an innovative polyglot architecture leveraging nine modern programming languages to maximize safety, performance, and cryptographic governance.

Key Research Pillars

LAGOS is built upon six critical research pillars:

1. Enterprise Blockchain Scaling: Governance across multiple administrative domains.
2. Tail-Latency Minimization: Applying data center strategies to wide-area overlay networks.
3. P2P-driven Last-Mile Optimization: Reducing latency at the network edge.
4. Internet-scale DDoS Mitigation: High-speed traffic analysis and filtering.
5. MultiPath TCP (MPTCP) Evaluation: Leveraging path redundancy for throughput and reliability.
6. Federated SDN Orchestration: Decentralized control plane management.

Polyglot Architecture

LAGOS decomposes networking and governance logic into specialized modules, each implemented in the language best suited for its specific requirements.

Language Stack & Roles

LAGOS represents a unique integration of nine specialized programming languages:

Language	Role	Rationale
Pony	Core Routing	Actor model with reference capabilities for race-free high-speed execution.
Gleam	Orchestration	Scalable, fault-tolerant distributed logic on the BEAM VM.
Move	Governance	Resource-oriented paradigm for safe management of overlay assets.
Clarity	Policy	Decidable smart contracts for predictable governance outcomes.
Noir	ZK-Audit	ZK-SNARK DSL for generating accountability proofs.
Cairo	Proofs	CPU-like STARK-provable programs for complex arithmetic.
Lurk	Verification	Recursive SNARKs for provable evaluation of complex governance rules.
Roc	Optimization	Purely functional language compiling to machine code for time-critical ops.
Unison	Deployment	Content-addressed functions for seamless distributed logic updates.

Repository Structure

• core/: Primary execution logic (Pony, Gleam).
• contracts/: Smart contracts for governance (Move, Clarity).
• proofs/: Zero-knowledge proof circuits (Noir, Cairo, Lurk).
• logic/: Optimization algorithms and MPTCP logic (Roc).
• fns/: Content-addressed function primitives (Unison).
• deploy/: MPTCP testbed and orchestration scripts.

Getting Started

Automated Setup

For a quick setup of all nine specialized toolchains and their dependencies on Linux, run the provided setup script:

chmod +x setup.sh
./setup.sh

Note

Lurk Stabilization: The setup.sh script is configured to automatically stabilize the lurk toolchain via Docker if a local binary is missing and Docker is available. This ensures parity across distributions with varying C++ toolchains (e.g., Ubuntu 24.04).

After the script completes, restart your terminal or source your shell profile (e.g., source ~/.bashrc) to update your environment variables.

For a detailed breakdown of all 13 installation steps and background services configured by this script, see the Setup Guide.

Manual Prerequisites

• Ponyup (Pony & Corral)
• Gleam
• Sui CLI (Move)
• Clarinet (Clarity)
• Nargo (Noir)

Documentation & Usage

For a detailed end-to-end explanation of the LAGOS workflow and specific command-line instructions for all nine toolchains, please refer to the:

👉 LAGOS USER GUIDE

End-to-End Simulation

To see all 5 phases of the LAGOS architecture working together automatically (from orchestration to zero-knowledge auditing), you can run the provided execution script:

./run.sh

This script will sequentially execute the Gleam, Pony, Roc, Move, and Noir components, displaying the output of each phase to demonstrate the complete lifecycle of a network event.
