The march of our cost-efficient Oracle continues with the arrival of Scribe on Arbitrum, granting access to decentralized, verifiable data for 100+ DeFi dapps.

Few blockchain Oracle providers have gone through the trouble of creating a dashboard, allowing anyone to glean insight into what is happening to generate the final value the Oracle reports. This lack of transparency is troubling.

We proudly announce that Scribe, our revolutionary new Oracle design, is now live on Mantle, bringing the same security and trust assumptions that power MakerDAO, Spark, and others to the burgeoning Mantle Ecosystem.

We are excited to announce the launch of the USDM/USD Oracle on Polygon zkEVM. Designed by Chronicle, this price Oracle will facilitate access to significant new markets for Mountain Protocol’s USDM yield-bearing stablecoin.

Chronicle Protocol has a long history. Born in 2017, it is still one of the oldest, continuously operating protocols in the space. Scribe, on the other hand, is new and novel. But what is it? In this short piece, we will dive deeper into this novel Oracle design recently launched by the core contributors to Chronicle Protocol, Chronicle Labs.

In Q4 of 2023, we opened up access to the protocol outside of MakerDAO for the first time and, with it, announced that Scribe, our groundbreaking new Oracle, would launch first on Polygon zkEVM.

Blockchains are blind. They don’t see anything that happens outside of the chain. They do not see the weather; they don’t know the price of a non-native cryptocurrency or the outcome of a football match. Applications built on the blockchain need access to information. For this, they rely on an intermediary, or in this case, a smart contract called an Oracle.

Towards the close of 2023, we announced ourselves to the world.

What was already well known in data and DeFi circles as the Oracle Core Unit of MakerDAO was now Chronicle Protocol, and, for the first time, it was made available outside of the MakerDAO ecosystem.

Oracles, originally invented to deliver price feed data, have grown to enable much more, including cross-chain token bridges, random number generation, and cross-chain messaging. Yet the commercial landscape remains relatively undeveloped.
