Ethereum, the blockchain that enabled smart contracts and underpins much of web 3.0, is moving to proof of stake. This change in consensus mode, called a “merge,” will likely take place on September 15. Until now, this mechanism for verifying information deposited on the blockchain has relied on complex mathematical calculations. The first user who finds the solution, thanks to powerful computers, receives a reward in cryptocurrency. But this operation, called “proof of work” (proof of work in English), consumes large amounts of energy.
