proof

Proof-of-stake is a mechanism for achieving consensus on a blockchain. Blockchain is a technology that records transactions that can’t be deleted or altered. It’s a decentralized database, or ledger, that is under no one person or organization’s control. Since no one controls the database, consensus mechanisms, such as proof-of-stake, are needed to coordinate the operation of blockchain-based systems. While Bitcoin popularized the technology, blockchain is now a part of many different systems, enabling interesting applications such as decentralized finance platforms and non-fungible tokens, or NFTs. The first widely commercialized blockchain consensus mechanism was proof-of-work, which enables users to reach consensus by solving complex mathematical problems. For solving these problems...

When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at Brookhaven National Laboratory discovered something perplexing. Muons – a type of subatomic particle – were moving in unexpected ways that didn’t match theoretical predictions. Was the theory wrong? Was the experiment off? Or, tantalizingly, was this evidence of new physics? Physicists have been trying to solve this mystery every since. One group from Fermilab tackled the experimental side and on April 7, 2021, released results confirming the original measurement. But my colleagues and I took a different approach. I am a theoretical physicist and the spokesperson and one of two coordinators of the Budapest-Marseille-Wuppertal collaboration. Th...
