Someone asked: Who is Sergey Nazarov?
I usually answer like this: Sergey Nazarov is a co-founder of Chainlink, which he founded with Steve Ellis. Smart contracts on the blockchain can't access internet data on their own; they rely on oracles to write external data onto the blockchain. This is what's commonly known as the “oracle problem.”
