Project Brief

Across America, 3,000+ local governments and 60 million residents and stakeholders (city governments, NGOs, SMEs) in underserved communities lack access to the data infrastructure that has the ability to offer diverse datasets and city-wide microdata to inform pubic policy, private-public benefit programs, and business decisions. Effectively locking these communities out of access to public services and the modern digital economy alike. This creates real, measurable harm.

Locale Network is building an L2 Network focused on empowering communities through DeFi, RWA, and Smart City services, through an ecosystem of products we call “City-Chains”. Privacy-centered, modular, and regional data networks offering access to vast amounts of micro-level data to local stakeholders as a public good; empowering local stakeholders and communities to additionally leverage Web3 liquidity for local services.

That said, this proposal is mainly about developing an open-source SDK that lets anyone create a data layer of off-chain information for use with Arbitrum Mainnet or Orbit Chains. Use cases include:

  • For Local Institutions: Giving governments, NGOs, and policymakers access to privacy-preserving, real-time data for smarter decisions. For example, using this data to improve public services, allocate resources efficiently, and plan for economic growth in underserved communities. (See examples below)

  • For Web3 Investors: Opening up real-world asset opportunities like business lending, auto and health insurance through DeFi. This bridges global liquidity with local communities, unlocking funding and economic opportunities. For Arbitrum investors, it’s a transparent way to access real-world financial services while supporting underserved areas. (See examples below)

Here are examples of how our tools could benefit different stakeholders:

For Governments & Stakeholders (Smart City Data and Services):

  • Example 1: Deploy intelligent traffic systems that share mobility data between public and private transit providers.

    • Benefit: Reduces congestion and emissions while improving public safety and transportation infrastructure.

  • Example 2: Use real-time health data, like opioid levels in wastewater, to predict and prevent overdoses (similar to Cary, N.C.).

    • Benefit: Provides hyper-local insights and enables tailored interventions for community health challenges.

For dApp Developers (DePIN & the Machine Economy):

  • Example 1: Create dynamically adjusting smart contracts for small business loans, tied to real-time financial data, and tokenize these loans for RWA trading.

    • Benefit: Monetizes real-world assets, offering transparent, encrypted loan health data directly to on-chain investors, eliminating the need for APIs or oracles.

  • Example 2: Build decentralized auto insurance and DMV services powered by real-time vehicle data.

    • Benefit: Gives Web3 investors access to new financial products tied to real-world services, diversifying their portfolios beyond speculative markets or staking yields.

Our approach builds on what platforms like ZenCity have started. While ZenCity uses social media sentiment data to serve 140+ cities and has raised $100M+, we’re expanding this concept. By integrating IoT data, machine-to-economy frameworks, and dApps with an SQL-backed Arbitrum off-chain infrastructure, we aim to create a more comprehensive and impactful ecosystem for both local communities and the Web3 space.

Solution:

Core Features:

Locale {Core} is a modular, decentralized infrastructure stack designed to power smart city applications and data economies. Our solution enables the secure ingestion, processing, and monetization of real-world IoT data from city infrastructure using a multi-layered Web3 architecture. We have been able thus far to accomplish this without Oracles or a central third party necessary. At its core, Locale enables:

Real-World Data Ingestion & Encryption

IoT devices (e.g., traffic sensors, air monitors, smart meters) submit raw data to a lightweight Cartesi node. These nodes handle initial processing and encryption. Data is encrypted either locally on-device or within Cartesi machines using a hybrid approach (AES-GCM for fast encryption, zk-compatible schemes for verifiability).

Off-Chain Storage, Compute, and Data Availability via 0G

Encrypted data is then offloaded to the 0G network, which acts as a unified backend layer offering:

  • 0G Storage: Decentralized, verifiable blob storage for encrypted payloads

  • 0G Compute: FHE-compatible compute layer for encrypted analytics, anomaly detection, or pattern recognition

  • 0G DA Layer: Serves as the verifiable rollup state host for cross-chain access, replacing our reliance on centralized databases or Cartesi node SQLite storage that aren’t scalable.

  • 0G AI Compute Custom LLM training and inference fine-tuned to the needs of local communities without sacrificing decentralization.

Verifiable Smart Contract Interactions on Stylus

Stylus smart contracts on our Arbitrum Orbit L2 chain verify zkProofs and FHE results from 0G before triggering any automated workflows. For example:

  • A “bad air quality” alert triggers a real-time voucher

  • A detected pothole triggers a work order NFT

  • A successful device uptime streak triggers stablecoin rewards

All smart contracts reference pointer-based metadata from 0G and proofs rather than ingesting full payloads, significantly reducing gas costs and improving performance.

What makes your project unique?

Verifiable Smart City Data, Not Just Sensor FeedsMost smart city platforms stop at raw data collection. Locale’s IoT SDK transforms device outputs into verifiable cryptographic proofs that power secure and automated public services:

  • Prove a service request was made without exposing user identity

  • Generate immutable logs of benefit access or citizen engagement

  • Deliver automated workflows that trigger smart contracts based on real-world activity

Privacy-Preserving by DesignLocale is one of the only IoT data platforms purpose-built with encryption and verifiability at its core:

  • Data is processed and encrypted at the SDK level with no raw data stored

  • Zero-knowledge proofs ensure governments and apps only see what’s necessary

  • Residents maintain full control and can monetize their verified data

Modular “City-Chain” Infrastructure Each city operates its own verifiable, forkable instance of Locale’s infrastructure:

  • Rollup-based execution using Cartesi with local state and compute

  • Connected to 0G for off-chain encrypted storage and AI inference.

  • Stylus smart contracts execute on verifiable proofs, not assumptions

Truly Open and InteroperableLocale’s IoT SDK and City Chain infrastructure is designed to prevent vendor lock-in:

  • Open-source tooling for cities and developers

  • Compatible with existing civic data systems and protocols

  • Interoperable with any smart contract platform via zkProof submission

Designed for Scale in Resource-Constrained EnvironmentsLocale doesn’t require a $5M investment to launch a smart city stack:

  • Lightweight deployment with modular components

  • Built to serve small-to-mid-sized cities with underserved populations

  • Optimized for affordability, uptime, and long-term data sovereignty

How Will You Integrate 0G?

1. Encrypted Data Storage Layer – 0G handles the permanent, verifiable storage of all data ingested through the IoT SDK. This includes resident-submitted forms, sensor readings, eligibility documentation, and economic activity logs. Instead of storing raw data in our execution layer, we store references (hash pointers) to encrypted blobs stored on 0G, with built-in content verification and proof-of-availability.

  • Benefit: Enables trust-minimized data pipelines with cryptographic auditability while preserving resident privacy.

  • Pain Point Solved: Eliminates centralized storage bottlenecks and risks of tampering or data leakage.

2. AI Compute & Inference Layer – 0G’s compute layer enables execution of machine learning models on encrypted data. Inference happens without decrypting the original input, allowing us to process sensitive resident data (e.g. eligibility, patterns of economic behavior, or service usage) with full privacy guarantees.

  • Benefit: Enables custom LLMs and AI agents trained on regional data and fine-tuned to offer local stakeholders insight to inform their operational decisions (Public policy evaluation, community program strategies, marketing campaigns, etc.), based on private data without exposing it.

  • Pain Point Solved: Removes the need to choose between data utility and data privacy.

3.Cryptographic Proof & Data Availability Layer – Every interaction with 0G generates a verifiable proof that can be checked by smart contracts on our Arbitrum Orbit chain. This includes proofs of storage, computation correctness, and data availability. Our Stylus contracts ingest and validate these proofs before approving any action.

  • Benefit: Ensures full end-to-end verifiability of data used in decision-making and financial transactions for local stakeholders and DeFi users.

  • Pain Point Solved: Adds trustless enforcement to real-world workflows without centralized oracles or middleware.

Integrating 0G significantly reduces our infrastructure costs by eliminating reliance on Cartesi VM SQLite for storage, shrinking Cartesi VM memory usage, and offloading compute-heavy verifiability from our execution layer. With encrypted blob storage and verifiability on 0G, we reduce cloud hosting fees, remove redundant encryption modules, and avoid expensive on-chain data storage. All while gaining faster, verifiable performance, and the ability to train LLMs specifically on city-wide data and offer it to local stakeholders as a public good. Our early research show over 90% cost savings per payload stored and a 70% drop in compute resource requirements.
