As Ethereum marks its tenth anniversary, we’re reflecting on ten moments that shaped Chronicle’s journey—from the earliest experiments in DeFi to powering the next wave of real-world asset tokenization. Chronicle was built for the long game: to bring trustworthy, high-integrity data onchain. Here are ten milestones where that vision took root and scaled.
1. 2017 – Ethereum’s First Onchain Oracle Born Inside MakerDAO
Chronicle’s oracle architecture originated in 2017 within Maker (now known as Sky Protocol), as part of the engineering effort behind the Dai stablecoin. Back then, the goal was simple but novel: reliably bring price data onchain to support a decentralized stablecoin. That led to Ethereum’s first onchain oracle system.
2. 2021 – Chronicle Secures 20B+ in Assets
By the end of 2021, Chronicle was securing over $20 billion in onchain assets through its oracle infrastructure. This milestone validated the protocol’s reliability and security, marking its emergence as a core pillar of DeFi infrastructure.
3. 2023 – Chronicle Spins Out to Scale Beyond Maker
In September 2023, Chronicle spun out as an independent oracle provider. While it continues to power Sky Protocol, it now serves the broader DeFi and tokenization ecosystems, enabling reliable data feeds for a growing network of applications, builders, and chains.
4. 2023 – Launch of Scribe
The same year, Chronicle launched Scribe, its gas-efficient oracle using Schnorr signature aggregation for the first time in an oracle system. Scribe shifts the burden of signature computation offchain, using Schnorr aggregated signature (MuSig2) to combine multiple validator signatures into a single compact "super-signature" submitted onchain. This dramatically reduces calldata size and gas costs by over 68%.
5. 2023 – ScribeOptimistic Launches: Fast, Fraud-Proof Oracles for L1s
To address the specific pain points of L1 blockchains such as expensive calldata —Chronicle launched ScribeOptimistic. ScribeOptimistic builds upon Scribe, Chronicle’s extremely gas-efficient Oracle based on aggregated Schnorr signatures. It enhances Scribe by adding an optimistic poke functionality, opPoke() which enables offchain verification of Schnorr signatures, reducing even further the gas costs.
6. 2024 – Launch of the Verified Asset Oracle (VAO)
Chronicle expanded its mission beyond DeFi with the Verified Asset Oracle, enabling onchain access to trusted data about offchain assets—Treasury Bills, private credit, fiat, gold, and more. VAO ensures data integrity and auditability for asset-backed tokens in compliant ecosystems.
7. 2024 – Chronicle Points: The First Community Rewards Campaign
September 2024 saw the debut of Chronicle Points, a community rewards initiative tied to SKY. Users who supply USDS become eligible for points, part of an evolving onchain incentives system.
8. 2024 – Scaling to 1,000+ Oracle Deployments
By the end of 2024, Chronicle had deployed over 1,000 oracles across multiple chains—supporting not just price feeds but a broader range of verified data services.
9. 2025 – Challenge Period Halved: Faster Updates
In January 2025, Chronicle halved its ScribeOptimistic challenge period from 20 to 10 minutes following 18 months of battle-tested performance. This marked a significant milestone in delivering faster updates while maintaining robust decentralized fraud-proof mechanisms.
10. 2025: Secures all 3 winners of Spark’s tokenization Grand Prix: BlackRock’s Buidl, Superstate, Centrifuge
Chronicle announced that its Verified Asset Oracle (VAO) technology is powering asset verification for the winners of Spark’s $1 billion Tokenization Grand Prix—BlackRock's BUIDL, Superstate, and Centrifuge—bringing transparency and verifiability to their tokenized assets.
Closing Words
Ten years ago, Ethereum gave us the canvas. Chronicle helped builders bring the data to paint on it.
Whether it’s price feeds, tokenized assets, or the next financial primitive, one thing remains true: trust begins with truth. And truth starts with reliable data. That’s what we’ve built, and that’s what we’ll keep building—together.
