For the purposes of the substrate Blockchain framework, the release of a Chainlink’s price feeds as a module or pallet in Polkadot terminology has been announced by Chainlink and Polkadot.
A Chainlink oracles can be integrated through a simplified library, because of the release Chainlink’s price feeds and also, any project building on the substrate of the framework , which includes Kusama Parachins, Polkadot and independent blockchains can also be integrated.
The announcement is premised on the existing partnership between Chainlink and Polkadot and which the alliance of the duo have led to the giving out a tangible product, that can enable a number of Defi-centric use om Polkadot.
The integration as a Substrate pallet means that it is up to each individual parachain to integrate and enable Chainlink oracles. This is a significant change from the architecture used on Ethereum, where Chainlink nodes regularly publish price data on each block, which smart contracts can then choose to reference or ignore.
On Polkadot, the more flexible design means that parachains that do not need Chainlink data won’t need to devote any blockchain space to it. On individual parachains, however, the end result may look similar to Ethereum. Peter Mauric, head of communications at Parity Technologies, compared the situation to “as if Chainlink were integrated as an opcode on Ethereum.”
