TLDR
- Anatoly Yakovenko, Solana’s co-founder, claims Ethereum’s Layer 2 solutions lack adequate quantum computing defenses
- According to Yakovenko, artificial intelligence may compromise post-quantum cryptographic systems faster than anticipated
- His proposed defense involves implementing two-of-three multisig configurations using separate signature schemes
- Falcon-512 post-quantum cryptography implementation is underway for Solana’s new user accounts
- Galaxy Digital’s Alex Thorn reports emerging agreement to preserve Satoshi Nakamoto’s Bitcoin holdings
Anatoly Yakovenko, the co-founder behind Solana, delivered a sobering message regarding quantum computing dangers facing cryptocurrency networks. His statements addressed vulnerabilities in Ethereum’s Layer 2 infrastructure, the limitations of post-quantum cryptographic solutions, and artificial intelligence’s potential role in future security breaches.
In a May 2, 2026 social media post, Yakovenko declared: “Ethereum L2s are not quantum safe, abandon all hope.” His commentary followed a developer announcement highlighting Solana’s advancements in quantum-resistant technology.
Ethereum’s Layer 2 scaling solutions—including Arbitrum, Optimism, Base, and zkSync—continue utilizing the Elliptic Curve Digital Signature Algorithm. These platforms depend on the secp256k1 elliptic curve, a cryptographic standard vulnerable to quantum computational attacks.
During transaction broadcasts, public keys become exposed on the blockchain. Sufficiently advanced quantum computing systems could exploit this information to derive private keys and compromise user funds.
Yakovenko described this vulnerability as a “harvest now, decrypt later” scenario. Malicious actors could archive current transaction records and deploy future quantum technology to decrypt them using Shor’s algorithm.
Zero-knowledge proof systems deployed in rollup technology present additional vulnerabilities. Protocols such as Groth16 and Plonk, fundamental to zkEVM architectures, depend on elliptic-curve pairings that sophisticated quantum computers could potentially compromise.
Solana’s Quantum Defense Plan
Solana is advancing implementation of Falcon-512, a cryptographic signature protocol engineered to withstand quantum computational attacks. Both Solana client implementations—Anza and Firedancer—are actively developing these security enhancements.
Falcon-512 will initially roll out for newly created Solana accounts. Development teams are simultaneously building transition protocols for legacy wallets, though no immediate network-wide emergency measures are scheduled.
Yakovenko extended his concerns beyond quantum computing, suggesting artificial intelligence represents an immediate security challenge. He warned that AI systems might crack post-quantum cryptographic defenses before cryptocurrency platforms achieve adequate hardening.
“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 mitigation strategy involves two-of-three multisignature arrangements that integrate distinct signature algorithms directly into Solana’s transaction processing layer via Program Derived Addresses.
Michael Egorov, founder of Curve Finance, questioned whether formal verification methodologies could mitigate these vulnerabilities. Yakovenko responded that verification tools only prove effective when developers understand precisely which properties require verification.
Bitcoin’s Quantum Question
Regarding Bitcoin, Alex Thorn from Galaxy Digital identified an emerging community consensus concerning Satoshi Nakamoto’s approximately 1.1 million Bitcoin holdings.
These assets remain distributed across an estimated 22,000 Pay-to-Public-Key addresses, each containing 50 Bitcoin. Thorn explained that quantum attacks would necessitate individual cracking of each separate address rather than a single comprehensive breach.
He observed that Bitcoin markets routinely process selling pressure exceeding one million Bitcoin. This market depth suggests the network could withstand catastrophic scenarios without fundamentally undermining property rights.
Meanwhile, Cardano and Algorand are developing independent post-quantum research initiatives. Ripple has committed to implementing quantum-resistant protections for its token by 2028. Bitcoin’s post-quantum preparedness remains in preliminary planning phases.
