Monsieur-TK : Bitcoin et Crypto

LA FIN D’ETHEREUM ? (C’est sérieux)

Vitalik Buterin, one of the co-founders of the Ethereum project, has recently broken his silence regarding the looming quantum threat to the crypto ecosystem, particularly Ethereum. He stresses the urgent need for the Ether network to evolve and transform as quickly as possible to counteract this threat. However, this necessary transformation comes at a cost, potentially turning the currently fast and scalable blockchain into a slow, heavy, and extremely expensive system to operate. This leads Buterin to pose two critical questions: first, are we willing to sacrifice Ethereum's performance and flexibility to ensure its long-term survival? And second, and perhaps more importantly, are the funds in older crypto wallets, those not updated in years, still secure, or have they already been compromised by this quantum threat? To understand why Buterin is so concerned, it's essential to grasp how cryptocurrencies are currently secured. The entire system relies on asymmetric cryptography, also known as ECDSA. Simply put, imagine your cryptocurrencies are stored in a safe with an access code so long that a classical computer would need more than the lifespan of the entire universe to decrypt it using brute force—trying every combination one after another. So, under normal circumstances, our funds are quite secure.
