- Galaxy Digital’s research head Alex Thorn reports emerging agreement within Bitcoin’s community to preserve Satoshi Nakamoto’s holdings
Anatoly Yakovenko, the co-founder behind Solana, has delivered a sobering assessment regarding quantum computing vulnerabilities threatening cryptocurrency networks. His analysis addressed Ethereum’s Layer 2 ecosystem, quantum-resistant security measures, and artificial intelligence’s potential role in compromising cryptographic systems.
During a May 2, 2026 social media exchange, Yakovenko declared: “Ethereum L2s are not quantum safe, abandon all hope.” His commentary emerged following developer communications highlighting Solana’s advancement in quantum-resistant technology implementation.
Ethereum’s Layer 2 scaling solutions—including Arbitrum, Optimism, Base, and zkSync—continue operating on the Elliptic Curve Digital Signature Algorithm framework. These networks depend on the secp256k1 elliptic curve, a cryptographic standard vulnerable to sufficiently powerful quantum computing systems.
During transaction broadcasts, public keys become permanently recorded on blockchain networks. Future quantum computers possessing adequate computational power could theoretically exploit this exposed information to derive corresponding private keys, granting unauthorized access to cryptocurrency holdings.
Yakovenko described this scenario as a “harvest now, decrypt later” vulnerability. Malicious actors could archive current transaction information and later deploy quantum computing capabilities to compromise security through Shor’s algorithm implementation.
Zero-knowledge proof systems integral to rollup architectures present additional concerns. Cryptographic frameworks such as Groth16 and Plonk, foundational to zkEVM implementations, depend on elliptic-curve pairing mechanisms that sophisticated quantum systems might eventually compromise.
Solana’s Quantum-Resistant Strategy
Solana has committed to implementing Falcon-512, a cryptographic signature framework engineered to withstand quantum computing attacks. Development teams behind Solana clients Anza and Firedancer are actively pursuing deployment of these security enhancements.
The initial rollout targets newly established Solana accounts for Falcon-512 adoption. Developers are simultaneously engineering transition mechanisms for pre-existing wallet infrastructure, although immediate network-wide modifications aren’t being mandated.
Yakovenko expanded his concerns beyond quantum computing alone, identifying artificial intelligence as a potentially more immediate security challenge. He cautioned that AI systems might compromise post-quantum cryptographic standards before the cryptocurrency sector achieves comprehensive implementation.
“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 explained.
His recommended countermeasure involves deploying two-of-three multisignature architectures that combine distinct signature algorithms. Solana’s transaction processing system would natively support this through Program Derived Address functionality.
Michael Egorov, the founder of Curve Finance, questioned whether formal verification methodologies might mitigate these vulnerabilities. Yakovenko responded that verification techniques only provide protection when developers understand precisely which aspects require verification.
Bitcoin’s Quantum Security Debate
Regarding Bitcoin, Galaxy Digital’s research director Alex Thorn identified strengthening consensus surrounding Satoshi Nakamoto’s approximately 1.1 million Bitcoin holdings.
These digital assets remain distributed across an estimated 22,000 Pay-to-Public-Key addresses, each containing precisely 50 Bitcoin. Thorn emphasized that quantum attacks would necessitate individually compromising each separate address rather than executing a single comprehensive breach.
He observed that Bitcoin markets routinely process selling pressure exceeding one million Bitcoin. This liquidity depth suggests the network could potentially withstand catastrophic scenarios without fundamentally undermining property rights frameworks.
Meanwhile, alternative blockchain networks including Cardano and Algorand are conducting independent post-quantum security research initiatives. Ripple has publicly committed to achieving quantum resistance for its token by 2028. Bitcoin’s community remains in relatively preliminary stages regarding post-quantum preparedness planning.
