Tezos Co-Founder on Protocol Upgrade

The video discusses Tezos, a cryptocurrency with a formal mechanism for seamless protocol upgrades, contrasting it with Ethereum's complex merge process. Tezos has upgraded 10 times with ease due to its design. The video highlights the importance of regular upgrades and scaling in blockchain technology. It also addresses energy concerns, noting Tezos' use of proof of stake since 2018, which is more energy-efficient than proof of work. The Ethereum merge to proof of stake is seen as a positive step towards reducing the industry's carbon footprint.

In what ways does Tezos' proof of stake mechanism contribute to its lower energy usage compared to proof of work networks?

What impact does the transition of Ethereum to proof of stake have on the broader conversation about energy usage in cryptocurrencies?
