Because defi protocols cannot access raw data from other blockchains or websites, they rely on oracles to access market data. band protocol is an inter-chain oracle network that combines and connects real world data and APIs to smart contracts.
oracles are critical for the successful operation of defi applications. The rapid growth of the defi market has led to an increase in demand for these oracles. Defi projects can technically create their own orcale, but they need time and resources to develop them. And oracles such as band protocol and chainlink come into play here.
Band Coin was launched directly through Binance's IEO platform Binance Launchpad. For this reason, Band tokens can be purchased quickly and smoothly on Binance, one of the world's largest cryptocurrency exchanges, according to trade volume. I bought it, I trust it.
