L{CORE} is now open source. It's a complete, self-hostable stack for IoT device attestation—no external tokens, no per-proof fees, no vendor lock-in. Deploy it anywhere, verify any device, settle on any EVM chain.

GitHub: github.com/Modern-Society-Labs/lcore-sdk

At Locale Network, we're building City Chains. These are grassroots L3 networks that settle to Locale, our L2 base layer in Q3 2026. Together, they help cities deploy DePIN, ReFi, and RWA infrastructure. Real cities. Real utility. Real tokenized assets.

But we hit a wall.

IoT devices lie. Or rather, the data they produce can't be trusted on-chain. A sensor can claim it measured 72°F, but how does a smart contract know that's real? How do you verify on-chain that a solar panel actually generated 500kWh? How do you trust a traffic sensor's count?

This is the IoT trust problem, and it's been blocking real-world blockchain adoption for years.

Today's DePIN infrastructure is fragmented across dozens of separate L1 networks. Helium runs on Solana. Hivemapper has its own chain. IoTeX, Peaq, DePHY—each ecosystem demands its own token, its own validators, its own liquidity pools.

This creates real problems:

• Liquidity fragmentation — Every new DePIN L1 splits capital across yet another ecosystem

• Integration complexity — Bridging assets between chains adds friction and risk

• Adoption barriers — Cities and enterprises don't want to manage multiple tokens and networks

• Pay-per-proof fees — Attestation services charge per verification, killing margins for high-volume IoT

• Vendor lock-in — Once you build on a specific chain, migration is painful

We needed something different. Infrastructure you own. No external tokens. No per-proof fees. Deploy on the chains where liquidity already exists. All without sacrificing the minimization of centralization, trust, or security and data privacy risks.

L{CORE} is infrastructure, not a service. It's a complete attestation stack you deploy yourself:

1. Device Identity with did:key

Every device gets a decentralized identifier (DID) using the did:key format. No centralized registry, no permission needed. The device owns its identity through a secp256k1 keypair.

2. Cryptographic Signatures with JWS

Devices sign their sensor readings using JSON Web Signatures (JWS) with the ES256K algorithm. This creates fraud-provable attestations—anyone can verify the signature came from that specific device.

3. TEE Verification

The Attestor runs in a Trusted Execution Environment. It verifies device signatures before data ever hits the blockchain.

4. Fraud-Provable Settlement

Cartesi provides a full Linux runtime inside a RISC-V virtual machine. Every computation is deterministic and fraud-provable. We run SQLite inside Cartesi for complex queries and persistent state.

5. EVM Finality

Settlement happens on your chosen Arbitrum Orbit chain with compatibility across the ecosystem.

Incubated in the DAO's DDA3 grants program, L{CORE} takes advantage of Arbitrum's Orbit stack, which enables anyone to launch application-specific L2s and L3s. City Chains are L3 networks with plans to deploy an L2 network, Locale, as the base settlement layer across each participating city. L{CORE} gives these chains native IoT capabilities without requiring cities to adopt a completely separate network or token.

This is important. When discussing the deployment of smart infrastructure with a city, the last thing they want is another blockchain to learn, another token to manage, and another ecosystem to trust.

With L{CORE} + Arbitrum Orbit, IoT attestation is just a feature of your chain. Not a separate network to bridge to.

We built SDKs for actual IoT devices:

The C SDK is particularly important. Most "IoT blockchain" projects only support powerful devices with Node.js or Python runtimes. Real embedded devices—the ones actually deployed in the field—run on microcontrollers with kilobytes of RAM.

Our C SDK runs on ESP32 and similar microcontrollers, enabling true edge attestation.

L{CORE} enables trustless verification across industries where real-world data meets on-chain value. Anywhere sensors produce data that needs to be trusted, attestation infrastructure can bridge the gap between physical measurement and blockchain settlement.

• Carbon credits — Emissions sensors sign readings at the source, enabling auditable, tamper-evident proof of capture rates for on-chain carbon credit issuance.

• Renewable energy — Solar inverters and wind turbines attest to generation data, enabling real-time REC minting and automated green energy trading.

• Smart cities — Traffic sensors, air quality monitors, and utility meters produce authenticated readings that can trigger on-chain actions like congestion pricing or pollution alerts.

• Supply chain — Temperature loggers and GPS trackers sign readings throughout a shipment's journey, creating an immutable chain of custody for cold chain and pharmaceutical logistics.

• Agriculture — Soil sensors, weather stations, and yield monitors produce attested data for crop insurance, carbon sequestration credits, and verifiable farm-to-table provenance.

Any sensor that produces data can now produce verifiable data on-chain.

We're continuing to build City Chains with Locale Network. L{CORE} is the attestation layer that makes it all work. Whether you're building DePIN infrastructure, tokenizing real-world assets, or deploying smart city applications, device attestation is the missing piece.

• DePIN builders — Deploy attestation infrastructure you own, without per-proof fees eating your margins at scale.

• RWA tokenization — Bridge physical sensors to on-chain assets with cryptographic proof that the underlying data is real.

• Smart city developers — Give cities self-hosted, open-source infrastructure they can own and operate on chains with resources to bridge the gap between on-chain liquidity and real-world communities.

• IoT + blockchain integrations — Stop bolting blockchain onto IoT as an afterthought and use infrastructure built from the ground up for device attestation.

L{CORE} might be what you need.
