Chainlink vs Pyth, what is the difference?

Chainlink vs Pyth is a comparison of two oracle networks, the services that bring outside data such as asset prices onto blockchains. Both serve lending apps, exchanges and other DeFi services. They differ in where their data comes from, how it reaches a blockchain and what their tokens do. For the basics, see what is an oracle.

Pyth vs Chainlink oracle, where does the data come from?

Chainlink aggregates at three levels, according to its FAQs. Professional data firms combine prices from many exchanges. Each Chainlink node takes the median of several of those firms. Then the network, called a decentralized oracle network, takes the median of all its nodes. Node operators are independent companies, such as data and infrastructure providers.

Pyth goes to the source. Its publishers are market participants, mainly trading firms, market makers and exchanges, that share prices they already see in their own operations. Pyth combines their prices and confidence ranges into one price and one confidence interval per asset. After its 2026 upgrade, five independent routers compute the median and sign each update, and a blockchain contract accepts it when at least three of the five signatures check out.

Push vs pull oracle, how do they deliver prices?

Chainlink's education hub defines the two models. A push oracle writes data on-chain on its own, either when the price moves past a set threshold or when a timer, called a heartbeat, runs out. A pull oracle produces reports off-chain, often several times a second, and the app brings the latest one on-chain only when it needs it.

Chainlink offers both. Its Data Feeds push prices and are used by lending markets such as Aave and Compound. Its Data Streams product is pull-based and aimed at fast trading apps.

Pyth is built around pulling. An app fetches a signed price and proof from Pyth's Hermes service and submits it in a transaction, where the Pyth contract verifies it. With Pyth's Pro contracts, each transaction carries its own signed price, checked on the spot.

How do the LINK and PYTH tokens and governance differ?

LINK is used to pay for Chainlink services and to compensate node operators. Node operators and community members can stake LINK as collateral backing service quality. The supply is capped at 1 billion. Chainlink's FAQs say on-chain upgrades go through multisignature contracts whose signers include node operators and Chainlink Labs, with timelocks on some changes.

PYTH is mainly a governance token. Holders stake it to vote in the Pyth DAO, one token per vote, over seven-day voting periods. Through Oracle Integrity Staking, publishers and delegators stake PYTH that can be partly slashed if a publisher supplies inaccurate data.

Can Chainlink and Pyth be used together?

Yes. Nothing stops an app from reading both, for example to cross-check prices. Supported chains differ and change over time. As of October 2026, Pyth's docs list several networks it no longer supports, so check each project's current list.
