TLDR
- Anatoly Yakovenko, Solana’s co-founder, issued a warning that Ethereum’s Layer 2 solutions lack quantum resistance
- According to Yakovenko, artificial intelligence may compromise post-quantum cryptographic systems sooner than anticipated
- His suggested mitigation strategy involves implementing two-of-three multisig configurations using independent cryptographic signatures
- Falcon-512 post-quantum cryptography is being integrated into Solana for future accounts
- Galaxy Digital’s Alex Thorn indicates emerging agreement to preserve Satoshi Nakamoto’s Bitcoin holdings
Anatoly Yakovenko, one of Solana’s co-founders, delivered a sobering assessment of quantum computing threats facing the cryptocurrency ecosystem. His remarks addressed vulnerabilities in Ethereum’s Layer 2 infrastructure, limitations of post-quantum cryptographic solutions, and artificial intelligence’s potential to accelerate security breaches.
In a May 2, 2026 social media post, Yakovenko declared: “Ethereum L2s are not quantum safe, abandon all hope.” His comment responded to development updates highlighting Solana’s advancement in quantum-resistant technology.
Ethereum’s Layer 2 scaling solutions—including Arbitrum, Optimism, Base, and zkSync—continue to depend on the Elliptic Curve Digital Signature Algorithm. This cryptographic framework utilizes the secp256k1 curve, which sufficiently advanced quantum computing systems could theoretically compromise.
During transaction broadcasts, senders expose their public keys to blockchain networks. A quantum computer with adequate processing capability could potentially exploit this information to derive corresponding private keys and gain unauthorized fund access.
Yakovenko characterized this vulnerability as a “harvest now, decrypt later” scenario. Malicious actors could archive transaction information presently and deploy future quantum computing resources to decrypt it via Shor’s algorithm.
Zero-knowledge proof systems employed in rollup technologies also present theoretical vulnerabilities. Cryptographic tools such as Groth16 and Plonk, fundamental to zkEVM architectures, depend on elliptic-curve pairing mechanisms that sophisticated quantum systems might eventually compromise.
Solana’s Quantum Defense Plan
Solana is actively implementing Falcon-512, a cryptographic signature framework engineered to withstand quantum computing attacks. Both Anza and Firedancer, primary Solana clients, are progressing toward deploying these security enhancements.
Falcon-512 adoption is planned initially for newly created Solana accounts. Development teams are simultaneously building migration frameworks for legacy wallets, though no immediate network-wide transition is mandated.
Yakovenko expanded his concerns beyond quantum computing, highlighting artificial intelligence as an imminent threat vector. He suggested AI systems could potentially compromise post-quantum cryptographic protocols before the cryptocurrency sector properly reinforces them.
“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.
His recommended defense mechanism centers on two-of-three multisignature architectures, integrating multiple cryptographic signature frameworks natively within Solana’s transaction processing infrastructure via Program Derived Addresses.
Michael Egorov, founder of Curve Finance, questioned whether formal verification methodologies could mitigate identified weaknesses. Yakovenko responded that verification processes only prove effective when developers possess clear understanding of what requires verification.
Bitcoin’s Quantum Question
Regarding Bitcoin, Galaxy Digital’s Alex Thorn documented emerging consensus surrounding Satoshi Nakamoto’s approximately 1.1 million Bitcoin holdings.
These assets reside across an estimated 22,000 P2PK addresses, each containing 50 Bitcoin. Thorn emphasized that quantum attacks would necessitate individually cracking each address rather than compromising them collectively.
He observed that Bitcoin markets routinely process selling pressure exceeding one million Bitcoin. This liquidity depth suggests the network possesses resilience to withstand catastrophic scenarios without fundamental property rights violations.
Meanwhile, Cardano and Algorand are conducting independent post-quantum cryptography research initiatives. Ripple has committed to achieving quantum resistance for its token by 2028. Bitcoin’s post-quantum preparation remains in preliminary planning phases.
