Beacons
Light-weight, first-party data feeds that increase transparency, reduce cost, and scale data access for Web3.
Beacons allow smart contract developers to connect Web3 applications to continuously updated streams of off-chain data, such as the latest cryptocurrency, stock and commodities prices.
First-party transparency delivers security and efficiency
Operated by the market’s most trusted and reliable data providers, Beacons are a transparent, cost-efficient and scalable way for smart contracts to interact with the off-chain data they need.
-
Cost efficient
Traditional Web3 data feeds rely on networks of 3rd-party oracle nodes. Built on API3’s first-party oracles, Beacons cut out the middlemen and the hefty fees they collect.
-
Data source transparent
Beacons are fed directly from the API provider to the blockchain. There are no 3rd-party oracle nodes in the middle to attack. And developers always know exactly where their data came from.
-
Reputation matters
When data comes directly from a reputable source, the provider’s off-chain reputation comes with it. More transparency means more selectivity and security.
-
Scalable, up and down
Beacons are light-weight and highly scalable. Scale up for high performance chains. Scale down for a wide range of use cases that aren’t feasible with traditional data feeds.
