On February 9, the American professional baseball team based in Washington, D.C., the Washington Nationals, announced the team has partnered with Terra, the open-source blockchain platform and decentralized autonomous organization (DAO). The Washington Nationals detail that the team is a “leading innovator” and is “consistently introducing new technologies to enhance the fan experience.” Washington Nationals Ink Long-Term Deal With Terra Major League Baseball (MLB) team the Washington Nationals has partnered with the blockchain platform and DAO Terra, according to an announcement published by the team on Wednesday. The deal with Terra follows a slew of sports-related deals with crypto firms, but the MLB team will be the first to partner with an open-source blockchain project. In addition to the partnership, the algorithmic stablecoin UST that’s issued on the Terra blockchain will be “accepted as a payment method at Nationals Park as early as next season.” “The Nationals continue t...
Polkadot parachains can now choose to add Chainlink price feeds to their runtime.
Polkadot and Chainlink have announced the release of Chainlink’s Price Feeds as a module, or “pallet” in Polkadot terminology, for the Substrate blockchain framework.
The release means that any project building on the Substrate framework — which includes Polkadot and Kusama parachains, as well as independent blockchains — can integrate Chainlink oracles through a simplified library.
The announcement comes as the latest result of a long-standing collaboration between Chainlink and Polkadot, now offering a tangible product that can enable a number of DeFi-centric use cases on 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.”
The complete Chainlink integration is likely to be welcome news for DeFi-centric parachains like Moonbeam, Equilibrium or Acala, especially from the perspective of introducing Ethereum projects to Polkadot. However, there is likely to be additional development work required to adapt the Chainlink pallet for use with smart contracts.
Chainlink is used by a number of DeFi projects on Ethereum to read external market data — a critical necessity for lending protocols, in particular. The project recently began a shift toward focusing on more than just price data, a pivot that comes at the heels of introducing the Off-Chain Reporting architecture.
