Ethereum co-founder Vitalik Buterin rejected Liron Shapira's claim that artificial intelligence could undermine Bitcoin's security and cause a 50% price decline within two years. Buterin said the probability of AI breaking Bitcoin's hash function or proof-of-work system is tiny, while vulnerabilities affecting software clients, mining pools and network infrastructure can generally be addressed through upgrades without broad social consensus. He said his holdings already put roughly 90% of his net worth on the opposing side of such a wager. Bitcoin's proof-of-work network has produced about 2^96 hashes without a successful 51% attack, and Buterin has said AI can also strengthen defenses through formal verification. Contemporaneous accounts gave divergent Bitcoin price references, placing it near $64,000 to $65,000 in one case and at $79,564 in another, alongside $52.92 billion in futures open interest.
