Coinbase announced the launch of a ‘DeFi Price Oracle’ which to serve the crypto DeFi movement. According to Coinbase, the oracle is not a competitor, but an ‘additive’ to DeFi oracles like Chainlink.
Coinbase has launched a price oracle for BTC-USD and ETH-USD. The price feeds available via the Coinbase Pro API and can be used for a variety of decentralized applications.
Currently, the Chainlink price reference oracle is leading oracle service which is composed of independent nodes which are run by blockchain DevOps and security teams. It offers price oracles for more than 26 pairs of cryptocurrencies. These are composed of security reviewed, and sybil resistant.
However, price is largely dependent on markets and cannot be sourced from ‘trustless’ sources. This is essential even for regulatory compliance to rule out market manipulation claims. Now, Coinbase is proposing a way to make their market data on-chain in a trustless manner. The blog post notes,
Many blockchains and crypto-related services like exchanges aggregate their price references from other sources. Decentralized Exchanges (also a DeFi) will find great use of this application. Compound, a lending based DeFi platform has already signed up with the Coinbase Price Feeds.
Even Chainlink can make use of these exchange driven price nodes to offer a new set of price oracles for trading pairs.
