Chronicle Protocol

Chronicle Protocol started as the first-ever Oracle built on Ethereum in 2017, co-created by Niklas Kunkel to enable the creation of SAI—the precursor to DAI. Since then, the protocol has evolved into a high-performance, permissionless Oracle network capable of delivering verifiable, real-time data across multiple chains. It remains the exclusive data layer for MakerDAO, at times securing over $20 billion in assets.

At the center of Chronicle’s innovation is Scribe, a novel cryptographic primitive that slashes gas fees by over 60% on Layer 1 and 68% on Layer 2, enabling scalable, cost-efficient Oracle data delivery. This makes Chronicle not just faster and cheaper, but fundamentally more accessible than traditional Oracle architectures. Data transmitted through Chronicle can be validated end-to-end through The Chronicle Dashboard, establishing a transparent on-chain audit trail for every value reported.

Designed as blockchain-agnostic, Chronicle Oracles are currently live on networks like Ethereum, Arbitrum, zkSync, Polygon zkEVM, Mantle, and Base. Developers can subscribe or unsubscribe to specific Oracle feeds with a single click, while the network’s validator set—featuring names like Nethermind, Gitcoin, and Steakhouse Financial—ensures integrity and uptime through community-powered consensus.

Unlike centralized Oracle services, Chronicle Protocol operates on a fully decentralized architecture. Governance decisions, validator onboarding, and fraud proofs are all handled via community participation. If a Validator is found to be malicious, anyone can submit a fraud-proof, resulting in an automatic ban and slashing—turning decentralization into a measurable security feature. This system introduces a powerful new dynamic: users can not only trust the data but also verify and influence the network themselves.

As a competitor to services like Chainlink, API3, and Band Protocol, Chronicle Protocol stands out with its focus on verifiability, cost-efficiency, and community governance. It isn't just an Oracle—it’s the infrastructure for the decentralized future, where transparency isn't optional but fundamental.

Chronicle Protocol provides numerous benefits and features that redefine the standards for on-chain data infrastructure:

• Cost-Efficient Oracle Technology: Using its proprietary Scribe cryptographic primitive, Chronicle Protocol reduces Oracle gas fees by over 60% on L1 and 68% on L2, making frequent updates economically sustainable.
• Fully Verifiable Data: Every data feed processed by Chronicle is end-to-end verifiable, from source to smart contract. Users can audit real-time and historical feeds via The Chronicle Dashboard.
• Blockchain Agnostic: Chronicle Oracles support major blockchains including Ethereum, Arbitrum, Polygon zkEVM, zkSync, and more, with one-click subscription and unsubscription functionality.
• Decentralized Validator Network: Secured by 22 top-tier Validator nodes, including Infura, Etherscan, Gitcoin, and MakerDAO, ensuring redundancy and eliminating single points of failure.
• Fraud-Proof Enabled Security: Any participant can submit a fraud-proof against compromised Validators, triggering automatic bans and fund redirection—creating a verifiable and reactive defense layer.

Chronicle Protocol makes it seamless for developers, protocols, and validators to integrate or participate in a decentralized and verifiable data ecosystem:

• Explore the Dashboard: Visit chroniclelabs.org and launch The Chronicle Dashboard to view live Oracle feeds and validator performance metrics.
• Integrate an Oracle: Developers can use Chronicle’s plug-and-play interfaces to subscribe to available data feeds or request new Oracle integrations across supported blockchains.
• Become a Validator: Established blockchain participants can apply to join the decentralized validator set by submitting credentials and infrastructure details at the Validator Portal.
• Use Developer Docs: Access comprehensive resources through the Chronicle Documentation Hub to begin integrating secure, real-time data into smart contracts.
• Join the Community: Connect via Discord or Twitter to ask questions, propose improvements, or monitor governance proposals.
