Sergey Brin, Google co-founder and Alphabet president, said that he mines Ethereum together with his son and highly appreciated the potential of zero-knowledge proof technology.

Sergey Brin, who attended a meeting organized by British businessman Richard Branson on 8 July, as the tenth richest man on the planet as of June 2018, spoke about the potential of the blockchain technology in the context of solving global problems.

Sergey Brin claimed to see "tremendous opportunity" in the potential of zero-knowledge proof technology. Such technology can be used to confirm transactions without disclosing their details and, thus, saving privacy.

The event was also attended by Matt Sorum, Guns n'Roses ex-drummer, who emphasized the potential of blockchain to protect copyright.

“A user should be able to own content in a way that rewards the artist. When the blockchain came along, I said, this can happen. And the way it will work is through smart contracts.”

Neha Narula, director of the Digital Currency Initiative at MIT Media Lab, supported the speakers and called zero-knowledge proofs one of the most promising solutions in the field of blockchain for the near future.

“Basically, you will be able to prove that something is true, without revealing the reasons for why it’s true. So to prove you’re 21, you don’t have to show the official documentation that you’re 21. Zero-knowledge proofs are going to be very transformative in the next few years.”

The event was also attended by former employees of the Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC).
