How to ensure cryptocurrency security? Relying solely on blockchain technology is far from sufficient
Ultimately, cryptocurrency industry security is not just a technical challenge, but an ongoing commitment.
Navigating Web3 tides with focused insightsMasked robbers breaking into banks at night are a thing of the past. Today's thieves no longer need to figure out how to disable vault cameras or plan escape routes, because robberies no longer happen at locked safes but are completed instantly on blockchains. All hackers need is a single clever line of code and an exploitable vulnerability, and victims often only realize they've been compromised after the damage is done.
Breakneck technological advancement has given rise to increasingly sophisticated cybercrimes that are not only hard to prevent but also constantly evolving—so rapidly, in fact, that their innovation outpaces even the most advanced security solutions. Attackers continuously adapt to changes in the digital landscape by discovering new vulnerabilities and bypassing traditional defenses. This paradox raises a critical question: if the underlying blockchain technology is secure and robust, why do cryptocurrency exchanges continue to fall victim? In 2022 alone, crypto hackers stole over $3.8 billion. This wasn't achieved by cracking encryption algorithms, but by exploiting technological flaws and human error. Security challenges are growing more severe, compounded by a complex interplay of factors including technical limitations, human factors, regulatory disparities, and the ways digital assets are stored, traded, and stolen.
True security isn't just about technology—it requires a holistic approach addressing diverse and complex risks ranging from smart contract vulnerabilities and social engineering attacks to adapting to an ever-changing regulatory environment.
The Security Paradox Beyond Blockchain Technology
With quantum computing not yet practically realized, blockchain is widely considered secure due to its strong cryptographic foundation. However, this security mainly applies at the level of blockchain addresses and consensus mechanisms. Most cryptocurrency thefts actually occur at the intersection between blockchain and traditional financial systems—such as hijacking hot and cold wallets at exchanges, exploiting smart contract flaws, or through social engineering attacks. Centralized exchanges must maintain online-connected wallets to ensure liquidity, making them prime targets for hackers.
While decentralized finance (DeFi) protocols eliminate custody risks and offer users an alternative, they inevitably introduce new vulnerabilities. Even experienced developers can make mistakes when writing complex smart contract code.
Why Centralized Exchanges and DeFi Have Not Fully Solved Security Issues
The security strategies of centralized exchanges (CEX) and decentralized platforms reflect fundamentally different philosophies and trade-offs. Centralized exchanges like Bybit adopt multiple robust security measures, including multi-signature wallets, offline cold storage of over 95% of assets, and regular penetration testing conducted by cybersecurity experts. Nevertheless, centralized systems still face single points of failure and threats from internal personnel, meaning these measures cannot eliminate all risks entirely.
Decentralized platforms give users full control over their assets, eliminating custody risk, but also introduce new challenges. Although DeFi code is transparent and open to community audits, the immutability of blockchains means that once a vulnerability is exploited, it cannot be patched. Furthermore, the complexity of smart contracts makes them difficult for average users to navigate, revealing a dangerous gap between technical barriers and real-world usability. The solution lies in moving beyond the simple binary choice between centralized exchanges and decentralized platforms. Bybit is exploring hybrid models that combine the self-custody advantages of DeFi with enterprise-grade security layers, using AI-driven transaction monitoring to analyze over 5,000 risk parameters in real time. Such technological integration is crucial, but technology alone is insufficient. As AI-powered attacks grow more sophisticated—using machine learning to mimic normal traffic patterns—ongoing security training for both developers and end users remains essential.
Despite the evolving nature of cyber threats, Bybit remains committed to providing the highest level of security for its users. Beyond AI, we focus on enhancing intelligent, self-evolving security and risk management capabilities. Our systems not only learn from their own experiences but also analyze risk incidents and failures across the entire ecosystem, proactively identifying emerging attack techniques to ensure our security protocols stay ahead of new threats, thereby offering robust protection for users. This commitment is embedded not only in our infrastructure but also in our post-incident response practices. After any incident, Bybit immediately conducts a comprehensive forensic investigation, draws lessons from the experience, strengthens affected or potentially vulnerable systems, and maintains transparent communication with the community. These actions ensure we not only respond effectively to threats but also continuously improve our defenses and maintain control over the evolving landscape of cybercrime.
Balancing Regulation and Asset Innovation
Effective regulation may be the most powerful tool for enhancing crypto security—but only if implemented properly. Measures such as mandatory proof of reserves, standardized smart contract audit requirements, and international anti-money laundering cooperation can significantly reduce systemic risks without stifling innovation. However, overly broad regulations—such as treating all crypto assets as securities or restricting privacy-enhancing technologies—often create more problems than they solve.
Risk-based regulatory approaches emphasize focusing on actual threats rather than applying one-size-fits-all rules. The industry needs clear guidelines that help address security concerns while preserving the innovative potential of blockchain technology. Striking this balance is critical to building public trust in institutions and driving mainstream adoption of crypto assets.
In the final analysis, security in the crypto industry is not merely a technical challenge, but an ongoing commitment. The issue is not whether cryptocurrencies can be protected, but whether the industry is willing to make the necessary investments and difficult choices to turn security into reality. For Bybit, this means building architectures based on zero-trust principles, maintaining transparent security practices, and promoting threat intelligence sharing across the industry. Continuous security upgrades and post-incident responses are powerful proof of our proactive defense, user protection, and dedication to safeguarding the crypto ecosystem. In a rapidly evolving environment, security must never be an afterthought—it must be the foundation of everything we build.
