Algorand and Blockstack PBC's joint smart contract language, Clarity, is getting a data boost from Chainlink's oracle network.

  • The planned integration will see Chainlink's oracles (information source links for blockchain-based applications) feed data into Clarity's cross-blockchain smart contracts, starting with realtime price points.
  • Blockstack said in a press release that developers will get access to the entire Chainlink data library "in the near future" but did not provide a timeline.
  • The team-up comes ahead of Blockstack's planned Stacks 2.0 protocol upgrade. The startup's CEO Muneeb Ali slated mainnet rollout for late Q4 in a recent blog post update.
  • Clarity smart contracts, which will ultimately provide Algorand and Blockstack with inter-chain communications, are also set to debut at mainnet launch.
