Key Takeaways
- Anatoly Yakovenko, Solana’s co-founder, highlighted quantum computing vulnerabilities affecting Ethereum Layer 2 networks
- Artificial intelligence poses risks to post-quantum cryptography implementations, according to Yakovenko
- Two-of-three multisig configurations using independent signature schemes offer potential protection
- Falcon-512 post-quantum cryptography adoption progresses on Solana for new user accounts
- Bitcoin community consensus emerges around preserving Satoshi Nakamoto’s holdings, reports Galaxy Digital’s Alex Thorn
Anatoly Yakovenko, co-founder of Solana, delivered a serious warning regarding quantum computing threats to cryptocurrency infrastructure. His remarks addressed vulnerabilities in Ethereum Layer 2 solutions, artificial intelligence risks, and emerging post-quantum cryptographic measures.
In a May 2, 2026 social media post, Yakovenko declared: “Ethereum L2s are not quantum safe, abandon all hope.” His message responded to developer updates highlighting Solana’s advancement in quantum resistance capabilities.
Ethereum’s Layer 2 scaling solutions—including Arbitrum, Optimism, Base, and zkSync—continue using the Elliptic Curve Digital Signature Algorithm. These platforms depend on the secp256k1 curve, which quantum computing technology could compromise.
Transaction broadcasts expose sender public keys on the blockchain. Sufficiently powerful quantum computers could exploit this information to derive private keys and compromise wallet security.
Yakovenko described this vulnerability as a “harvest now, decrypt later” scenario. Malicious actors could collect transaction information today and deploy future quantum systems utilizing Shor’s algorithm to break encryption.
Zero-knowledge proof systems powering rollups face similar theoretical vulnerabilities. zkEVM implementations utilizing Groth16 and Plonk technologies depend on elliptic-curve pairings that sophisticated quantum computers might compromise.
Solana Implements Quantum-Resistant Measures
Solana advances implementation of Falcon-512, a cryptographic signature scheme engineered to withstand quantum computing attacks. Both Anza and Firedancer client teams actively develop these security enhancements.
Falcon-512 adoption targets new Solana accounts initially. Developers simultaneously create migration strategies for existing wallets, avoiding immediate network-wide disruptions.
Yakovenko extended his concerns to artificial intelligence, identifying AI as an immediate threat vector. He expressed concern that AI systems could compromise post-quantum cryptography before adequate industry hardening occurs.
“I think the biggest risk is that PQC signature schemes will get broken by AI, we don’t know all the implementation footguns even, let alone the math footguns,” Yakovenko stated.
He advocates for two-of-three multisig implementations that combine multiple signature schemes directly within Solana’s transaction processing through Program Derived Addresses.
Curve Finance founder Michael Egorov questioned whether formal verification could mitigate these weaknesses. Yakovenko responded that verification provides value only when developers understand what requires verification.
Bitcoin Community Addresses Quantum Preparedness
Regarding Bitcoin, Galaxy Digital’s Alex Thorn identified emerging community consensus surrounding Satoshi Nakamoto’s approximately 1.1 million Bitcoin holdings.
These assets reside across roughly 22,000 P2PK addresses containing 50 Bitcoin each. Thorn explained that quantum attacks would require individual address compromise rather than simultaneous exploitation.
He observed that Bitcoin markets regularly process selling pressure exceeding one million Bitcoin. This liquidity suggests the network could manage worst-case scenarios while maintaining fundamental property rights.
Meanwhile, Cardano and Algorand advance independent post-quantum research initiatives. Ripple committed to achieving quantum-proof status for its token by 2028. Bitcoin’s post-quantum planning remains in earlier developmental phases.
