Eli Ben-Sasson (StarkWare): "Energy efficiency has become a key issue".

👉 The news. StarkWare has announced the launch of its token.

👉 The background. The Israeli start-up is on everyone's lips and experts are raving about the capabilities of this Ethereum Layer 2.

👉 Why it matters. With the move to Proof-of-Stake, Ethereum is set to become more energy-efficient. With the development of Layers 2, this could explode its use.

THE BIG WHALE: This is your third time in Paris for EthCC. What do you think of the French ecosystem and how has it evolved?

ELI BEN-SASSON: Honestly, I think it's really impressive. It's clearly one of the most dynamic on the planet and it's no coincidence that there are so many people in Paris for this event. We came with more than 20 people from StarkWare to find out about other projects, particularly French ones, and also to see what's new in the Ethereum ecosystem.

Actually, Ethereum is preparing to move away from Proof-of-Work to Proof-of-Stake, which is more energy-efficient. What do you think of this change?
