Crypto’s Decentralization Myth Exposed: 16 Blockchains Can Freeze Your Funds at Will
Decentralized Networks Under Scrutiny as Report Reveals 16 Blockchain Networks Possess Built-in Fund-Freezing Mechanisms
A new report from Bybit’s Lazarus Security Lab has sparked concerns about the true level of decentralization on popular blockchain networks. The study, which analyzed 166 blockchain networks using a combination of AI-driven detection and manual code review, discovered that 16 major chains have built-in mechanisms to freeze or restrict user funds. This revelation challenges the notion of full decentralization among these networks.
Major Chains Found to Have Built-In Freezing Mechanisms
The report found that several prominent chains are equipped with hardcoded freezing functions, enabling developers or validators to halt transactions or lock specific wallets. Bybit’s researchers categorized these control mechanisms into three main types: hardcoded freezing, configuration-based freezing, and on-chain contract freezing.
Hardcoded freezing occurs when a blockchain has pre-programmed codes that allow freezing of funds at the protocol level. Ten blockchains, including Aptos, EOS, and Sui, rely on configuration files like YAML, ENV, or TOML to manage private blacklists accessible only to validators or foundations. These blacklists can be used to freeze funds via validator-level configuration changes.
Five networks, including BNB Chain, embed freezing features in their source code, allowing blacklisted wallets to be blocked at the protocol level. For instance, Heco Chain (Huobi Eco Chain) stands out as the only network using a smart contract-based blacklist. Bybit’s researchers discovered that these mechanisms introduce new risks of centralization and censorship.
Consequences of Fund-Freezing Mechanisms
While designed for security purposes, some experts argue that the existence of fund-freezing functions poses significant concerns about decentralization. "The existence of fund-freezing functions, even when implemented for security purposes, challenges the notion of full decentralization," Bybit’s researchers noted.
Moreover, their report revealed that 19 additional blockchains are capable of introducing similar features with minor protocol modifications. This has significant implications for users who may be unaware of these underlying limitations on blockchain immutability.
Impact on Crypto Industry and Decentralization Debate
The findings have sparked a heated debate within the crypto community over security versus decentralization. Supporters argue that such features are essential for responding to hacks or criminal activity, highlighting cases where court-authorized freezes helped recover stolen assets.
In contrast, opponents caution that freezing mechanisms can create central points of control, allowing foundations or validators to block transactions arbitrarily. This erosion of trust in blockchain immutability opens the door to censorship and challenges the fundamental principle of decentralization.
Timing and Significance
Bybit’s research assumes significance given recent high-profile hacking incidents within the industry. The exchanges’ experience with a $42.9 million cold wallet hack demonstrated both sides of the argument. Coordinated efforts with partners helped recover tens of millions in stolen funds, while their intervention reinforced how centralized power has become.
Recommendations and Conclusion
While Bybit’s report stops short of offering policy recommendations, it emphasizes the importance of transparency around built-in freezing features. They advocate for clearer disclosures to prevent misleading users about control over their own assets. "Blockchains that include freezing capabilities should disclose them clearly," the authors urged.
