One of the biggest exchanges in the world decided to start an own Chainlink node. They want more accurate price-data, for themself and for customers too.

Kraken is an old and big exchange. Last year they get banking licenses in the USA, so now they are offering a wide range of traditional banking services, not only crypto-related solutions.
