The pool of staked tokens allows API3 to offer &#8220;Service Coverage&#8221; to customers in case of malfunctioning dAPIs, which helps them to mitigate risk.

The protocol can send data to multiple blockchains thanks to Cosmos&#8217; IBC (Inter-Blockchain Communication) protocol. Users can also write their own oracle scripts to receive data streams from the real world, from multiple markets such as stocks, assets, commodities, and crypto, to real-life events such as weather, sports, and more.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Band Protocol uses a Delegated Proof-of-Stake (DpoS) consensus algorithm. When smart contracts request data, the protocol chooses a random validator with a high amount of staked $BAND to take on the job. Validators must stake $BAND, the protocol&#8217;s inflationary token, before retrieving data, and other validators vote on the authenticity of said data.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some of Band Protocol&#8217;s notable backers and integrations are Binance, Fantom, Moonriver, and Iron Bank.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">5.

Without oracles, smart contracts would have limited capabilities outside of the blockchain world. One common misconception is that an oracle is a data source itself. This is incorrect since an oracle is a layer that sources and verifies external information.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A blockchain oracle is a third-party platform that bridges smart contracts with the outside world and vice versa. Most of these platforms use network oracles that search, query, verify, and retrieve real-world data to smart contracts running decentralized applications (DApps); some others use APIs (Application Programming Interfaces).
