Polkadot and Chainlink announced the launch of a price feed as a module or ‘showcase’ in Polkadot’s terminology for the substrate blockchain architecture.

The release means that any project that builds on the substrate framework that includes an umbrella from Polkadot and Kusama, in addition to standalone blockchains, can integrate Chainlink Oracle through a streamlined library.

This announcement is the latest product of a decades-long collaboration between Chainlink and Polkadot, and is now offering a real product that can provide a range of DeFi use cases on Polkadot.

Integration as tray liner means each individual umbrella must integrate and activate Oracle Chainlink. This is a major change from the architecture used in Ethereum, as Chainlink nodes regularly publish price data for each block that smart contracts can use to link or ignore.

At Polkadot, the more flexible design means that the parachute that does not need Chainlink data does not need to allocate any blockchain space to it. However, in some umbrellas, the end result might look like Ethereum. Peter Morrick, Communications Director at Parity Technologies, likened the situation to “as if Chainlink has been integrated as Ethereum’s running code.”

Full integration with Chainlink is likely welcome news for DeFi-focused paragliders like Moonbeam, Equilibrium or Acala, especially as it relates to the implementation of Ethereum projects at Polkadot. However, further development is likely to be required to adapt the Chainlink platform for use with smart contracts.

Chainlink is used on a number of Ethereum DeFi projects to read offshore market data, which is especially important for lending protocols. More recently, the project started to shift towards focusing on more than just pricing data, and this happened right after the off-chain reporting architecture was implemented.
