Key Insights:
- The immediate threat might be around the infrastructure instead of Bitcoin’s core cryptography.
- AI could make both sides stronger, and make this race accelerate to find vulnerabilities sooner.
- Future security incidents could rely heavily on the ability to coordinate upgrades to Bitcoin.
Vitalik Buterin has rejected claims that artificial intelligence could undermine Bitcoin’s security and trigger a price collapse exceeding 50%. The Ethereum co-founder challenged the forecast on September 7, arguing that Bitcoin can address most AI-driven threats through technical upgrades.
Silicon Valley investor Liron Shapira had predicted a sharp Bitcoin decline within two years. He assigned a 50% probability to the outcome. Shapira argued that increasingly capable AI systems could weaken confidence in Bitcoin’s security and robustness. His prediction was on the likelihood of AI finding major flaws.
Buterin, however, disagreed, and doubted the possibility of such a major breakdown.
I take the opposite side of that.
My basic reasons are that I am quite optimistic about cybersecurity in the long term and I see the primary problem as being getting the transition, and I expect BTC to handle at least any issues that do not require social consensus well…

Shapira responds to Buterin’s Forecast.
The conflict over Bitcoin’s security started when Shapira explained how he was worried about the future of security in Bitcoin. He claimed that AI will offer a chance to test some of the network’s perceptions of its own resilience.
His prediction did not identify a specific vulnerability or technical attack path. Instead, it focused on AI potentially undermining investor confidence.
Vitalik Buterin rejected that assessment and focused on Bitcoin’s ability to respond to technical threats. He said network-level attacks could often be addressed through upgrades to Bitcoin clients and mining pools.
Those changes would not necessarily require changes to Bitcoin’s monetary rules. They also would not require rewriting the blockchain’s transaction history.
Buterin drew a distinction between operational vulnerabilities and failures affecting Bitcoin’s cryptographic foundation.
He described the probability of Bitcoin’s hash functions or proof-of-work system suffering an actual break as extremely low. The disagreement therefore centers on how AI could affect Bitcoin’s security environment.
Bitcoin’s core security faces a different risk profile
Bitcoin relies on SHA-256 hashing and proof-of-work to secure its network. Miners compete to process blocks through computational work. A direct break would represent a much deeper threat than a conventional software vulnerability.
Buterin noted these problems have a low likelihood of appearing, despite the number of ways the technology can be used to disrupt the blockchain.
The attackers may exploit AI to identify vulnerabilities in wallet software and network infrastructure. It might also speed up the discovery of vulnerabilities in big code bases. However, defenders can use similar technology to review software and identify weaknesses earlier.
Bitcoin developers can also deploy software patches when conventional vulnerabilities emerge. This creates a different challenge from compromising the cryptographic systems securing Bitcoin’s consensus mechanism.
The following points highlight the central dispute.
- AI may accelerate vulnerability discovery across Bitcoin-related infrastructure.
- Software and mining systems can receive upgrades after developers identify operational weaknesses.
- A direct break of Bitcoin’s proof-of-work mechanism remains the less likely scenario.
The distinction matters because attacks against wallets or exchanges do not automatically compromise Bitcoin’s underlying ledger.
Security groups seek advanced AI tools
The broader debate has already reached Bitcoin’s security community. The Bitcoin Policy Institute and more than 40 digital-asset organizations raised concerns during August. They urged major AI laboratories to support vetted security researchers.
The coalition argued that defenders need access to advanced AI systems before attackers gain an advantage. Several major cryptocurrency companies and Bitcoin development groups supported the initiative.Supporters included Block, Coinbase, Strategy, MARA, Galaxy, BitGo, Brink and Trezor.
The proposal called for controlled access to advanced models and secure testing environments. Researchers could then use those systems to identify vulnerabilities and test potential fixes. That effort reflects a growing concern about the changing balance between attackers and defenders.
AI could automate parts of cybersecurity research and increase the speed of vulnerability discovery. Yet Vitalik Buterin’s position suggests Bitcoin can adapt to many of those risks without changing its core consensus rules.
The market debate extends beyond cryptography
Other market commentators have raised separate concerns about AI and Bitcoin.
Some argue that AI infrastructure could compete with cryptocurrency for investment capital, electricity and data-center capacity. Those arguments differ from Shapira’s security-focused forecast. They instead examine whether AI development could change capital allocation across technology markets.
Bitcoin showed no clear market reaction directly linked to the public exchange.
The cryptocurrency traded near $79,590 on September 7 and moved modestly during the session. Price of Bitcoin can be impacted by liquidity, derivatives positioning and other factors.
Exchange-traded fund flows, macroeconomic data and broader risk sentiment also affect market performance. Neither Shapira nor Buterin presented a formal model connecting AI development to a specific Bitcoin price outcome.
Their exchange instead highlighted competing views about technological risk and Bitcoin’s capacity to adapt.
Conclusion
Vitalik Buterin’s rejection of the forecast does not dismiss cybersecurity risks created by advanced AI. Instead, he separates manageable operational threats from a fundamental cryptographic failure.
His argument rests on Bitcoin’s ability to upgrade software and mining infrastructure when vulnerabilities emerge. The debate now focuses on whether defenders can adapt as quickly as AI strengthens potential attackers.
