Smart contracts are bustling with huge potential to redefine major industries in the world and for better.
Well, blockchain oracles can be defined as 3rd party services or middleware which serve to connect blockchain’s on-chain world with the off-chain or real-world data.
With blockchains evolving and crypto experts expecting a more enhanced role of smart contracts today, oracles are becoming even more significant these days.
Comparison between Centralized and decentralized oracles
Oracles can be primarily divided into centralized as well as decentralized oracles.
Centralized oracles serve as one single entity which fetches information from an off-chain source for smart contracts.
Unlike the centralized counterpart that relies on one external source, a decentralized oracle counts on several external sources to provide data to blockchain smart contracts.
Moreover, the decentralized ones assure comparatively faster operations. However, centralized oracles, although slower yet offer better security.
The DeFi scene is fast gaining traction in the current blockchain market and that's wonderful news anyday.
A major bunch of DeFi protocols, like MakerDao, Compound, Aaye or Uniswap, use oracles to source off-chain data.
The new oracle has gained huge popularity of late. In fact, the Bridge oracle IEO was completely sold out in just a few hours of the launch.
