Vitalik Buterin optimistic about Bitcoin’s resilience against cybersecurity threats

Vitalik Buterin, the co-founder of Ethereum, expressed confidence on September 7 that Bitcoin can handle emerging technical security challenges without relying on social consensus, arguing that simple client and mining pool upgrades would be sufficient to address network-layer threats. The comments directly counter a growing narrative in crypto circles: that artificial intelligence could pose an existential risk to Bitcoin, potentially causing its value to drop more than 50% over the next two years. Buterin’s verdict on the likelihood of anyone breaking Bitcoin’s core cryptographic elements, including its hashes and proof-of-work model? “Tiny.” The case for Bitcoin’s technical fortress Bitcoin’s proof-of-work system has accumulated roughly 2^96 hashes over its lifetime. The sheer computational weight behind the network means that mounting a successful attack would require resources that currently border on the physically impossible. Bitcoin has never experienced a successful 51% attack, the scenario where a single entity gains majority control of the network’s mining power and can manipulate transactions. Buterin’s argument hinges on a distinction between threats that require socia...
