The "Ultimate Security" Battle of Ethereum: How Can Ordinary People Get Ahead?

Have you ever wondered: when quantum computers become widespread in the future, will the private keys in your wallet and your crypto assets instantly become worthless?
While many still treat the "quantum threat" as a joke or marketing gimmick, Ethereum is already taking serious action.
Recently, Vitalik Buterin (V神) released a comprehensive quantum resistance roadmap for Ethereum on social media. This seemingly low-key technical document doesn’t hype or sensationalize but directly defines the underlying reconstruction direction for Ethereum over the next 5-10 years and sets the security endgame for the entire blockchain industry. V神 released the quantum resistance roadmap: — The "Ultimate Security" Battle of Ethereum!
In this "ultimate security" battle involving all Web3 participants, one keyword runs through the entire process: ZK.
I. Four Critical Weaknesses: Where Exactly Is Ethereum’s Quantum Risk?
In the roadmap, V神 openly lists the four major quantum security vulnerabilities currently present in Ethereum, each related to the safety of your and my assets:
1. Consensus Layer BLS Signatures: The core cryptographic tool used by Ethereum validator nodes to aggregate signatures and confirm blocks
2. Data Availability KZG Commitments: The current mechanism ensuring on-chain data integrity and tamper resistance
3. EOA Account ECDSA Signatures: The private key signature system we use daily for transfers and authorizations
4. Application Layer Zero-Knowledge Proofs: Including the many ZK projects using KZG, Groth16, and other ZK-SNARK schemes
These four components are not trivial peripheral functions. They cover the entire Ethereum chain—from "who keeps the ledger," "is the data tampered," "is your account secure," to "are privacy transactions trustworthy." In other words, once quantum computers break through, these four areas will be Ethereum’s most vulnerable points of attack.
II. The Way Forward: Why ZK Is the Ultimate Answer for Quantum Security
Faced with these four weaknesses, V神’s roadmap provides a clear and detailed solution approach. The core thread running through the entire solution is STARK (Transparent, scalable zero-knowledge proofs).
Consensus Layer: Immunize against quantum attacks at the root by replacing current BLS signatures with hash-based signatures and using STARK for signature aggregation. Moving away from elliptic curve cryptography, which is vulnerable to quantum attacks, toward hash functions, fundamentally sealing off the possibility of quantum hacking.
Data Availability: Reconstruct the trust base with STARK proofs, replacing the current KZG commitments. Although engineering challenges like the larger size of STARK proofs compared to raw data still need solving, V神 explicitly states that recursive STARK technology already has mature solutions.
EOA Signatures: Equip accounts with "quantum-safe locks" through native account abstraction (EIP-8141), allowing ordinary accounts to freely adopt any signature scheme. This effectively opens the door for all users’ wallets to access quantum-resistant signatures—whether hash-based or lattice-based—seamlessly.
Zero-Knowledge Proofs: Lower costs and maximize security—this is the most exciting part of the entire roadmap. Currently, on-chain verification of standard ZK-SNARK proofs costs about 300,000-500,000 gas; in contrast, quantum-resistant STARK proofs cost up to 10 million gas—costs that are unacceptable for privacy protocols and Layer 2 solutions.
V神’s ultimate solution involves recursive protocol-layer signature and proof aggregation. He envisions a scenario that could revolutionize the industry’s fundamental logic: a block could "contain" thousands of verification frames, each carrying 3KB signatures or even 256KB zero-knowledge proofs. But these raw data and computations, often hundreds of MBs, will never be stored on-chain. Instead, a single STARK proof will verify all these computations at once. Even block builders won’t need to do this themselves: it can be distributed across network nodes, with only one proof every 500 milliseconds.
III. Getting Ahead of the Curve: Understanding V神’s Roadmap and Ethereum’s Future Underlying Tech
1. ZK-Rollup: The natural testing ground for recursive proofs. zkSync processes tens of thousands of on-chain transactions daily, generating a ZK proof for each batch and submitting it to Ethereum. This embodies V神’s "proof aggregation" concept in large-scale real-world deployment. When Ethereum upgrades proof aggregation to a system-level capability, zkSync’s extensive engineering experience will be an irreplaceable core advantage.
2. Airbender Prover: A forward-looking technology layout. As the world’s fastest RISC-V zero-knowledge virtual machine, Airbender was designed from the start to support flexible switching between proof systems. When Ethereum transitions from KZG to quantum-resistant STARKs, zkSync is already fully prepared for this technological shift.
3. Prividium Privacy Solution: Addressing institutional-level quantum security needs. Prividium’s bank-grade privacy solution relies on ZK proofs to achieve verifiable, compliant privacy. In the future, quantum-resistant signatures will become a mandatory threshold for institutions entering Web3, and Prividium will be among the first to meet the dual standards of "quantum security + privacy compliance."
IV. The Guide for Ordinary People: Avoid Pitfalls, Seize Opportunities, Get Ahead
For us ordinary Web3 participants, this roadmap isn’t an unreachable technical document but a clear "avoid pitfalls + seize opportunities" guide. Three levels of opportunity are already in front of everyone:
First Level: Knowledge Upgrade, Reject FUD
Quantum threats have been hyped for many years. Some use it to create panic, claiming "quantum computing will kill blockchain"; others use it as a marketing gimmick to promote air coins and fleece investors. But V神’s roadmap tells us: Ethereum’s systematic quantum defense is already moving into engineering implementation and is fully feasible. Don’t be misled by panic rhetoric, and don’t let FUD disrupt your rhythm. True builders are already solving the problems.
Second Level: Deep Ecosystem Engagement, Focus on Certainty
V神’s roadmap consistently confirms one conclusion: ZK technology will become the core infrastructure for Ethereum’s future quantum security upgrades. As an ordinary participant, deep engagement with and use of zkSync ecosystem is a way to get ahead of future technological dividends.
- Use zkSync Era for daily transactions: experience its low fees and high speed
- Explore leading DeFi protocols and RWA platforms within the ecosystem: understand real-world Web3 applications
- Follow progress on institutional solutions like Prividium, and grasp the early rhythm of compliant asset onboarding
Third Level: Avoid Pitfalls, Reject Hype
Any technological narrative can be exploited by speculators to fleece investors. Here are three red lines to remember:
- Beware of projects claiming "quantum resistance" without real core development; the true core work is in the hands of the Ethereum Foundation and top-tier tech teams
- Don’t trust panic marketing about an imminent "quantum crisis"; V神’s upgrade window gives us 5-10 years for a smooth transition
- Regardless of when quantum computers arrive, protecting your mnemonic phrases and private keys remains the top priority for asset security
V. Conclusion: Position Yourself in the Certainty Trend
V神’s quantum resistance roadmap isn’t a temporary patch but a systematic, 5-10-year underlying overhaul. It demonstrates Ethereum’s resilience as the "world computer"—able to replace engines mid-flight and upgrade core cryptography without service interruption.
In this reconstruction, ZK technology has shifted from an "optional scalability solution" to Ethereum’s "system-level foundational language." As a leader in the ZK-Rollup space, zkSync has already secured key positions across technology, ecosystem, and institutional adoption.
For ordinary users, the greatest wealth secret in Web3 is never chasing fleeting hot trends but understanding the long-term certainty trend and standing on the right side of it.
