Examining the Impact of Blockchain Freeze Mechanisms on Decentralization
Key Takeaways:
- Bybit’s security team identified 16 blockchain networks that can freeze or restrict user funds, questioning the true decentralization of these networks.
- The freezing capabilities on these blockchains fall into three categories: hardcoded methods, configuration-based methods, and onchain smart contract methods.
- Specific blockchains like BNB Chain, VeChain, and Heco possess unique mechanisms for asset control, potentially compromising decentralization.
- Concerns rise over censorship and centralization as security features designed to protect user funds could introduce vulnerabilities in trust.
- The presence of administrative controls and emergency measures in these blockchains blurs the line between security and centralization.
Blockchain technology has long been heralded as an advancement toward a decentralized future, where power is distributed, and user autonomy is maximized. However, recent findings by Bybit’s Lazarus Security Lab have brought to light the ability of certain blockchain networks to freeze or restrict user funds, sparking a renewed conversation about decentralization and control within the crypto sphere.
Revealing the Capacity to Freeze Funds
In a comprehensive study analyzing 166 blockchain networks, Bybit—a well-known player in the crypto exchange world—revealed that 16 of these networks possess the capability to freeze or restrict user funds. The report detailed the methods through which these networks exert such control, shedding light on potential centralization concerns. This discovery has reverberated through the crypto community, raising fundamental questions about the decentralization that blockchains promise to uphold.
Mechanisms of Control
These blockchain “freeze” functions are not homogenous. Bybit’s investigation categorized them into three distinct methodologies:
- Hardcoded Methods: Certain blockchains, like the Binance-backed BNB Chain, were found to have freezing capabilities directly embedded within their source code. This means that without access to crucial parts of the codebase, certain transactions can be halted.
- Configuration-Based Methods: Other blockchains employ a system of control via local configuration files accessible primarily to a select group such as validators or core developers. Aptos, Eos, and Sui fall into this category, where configurations such as YAML or ENV files dictate the freezing parameters.
- Onchain Smart Contract Methods: Uniquely, the Heco chain manages its blacklist through smart contracts on the blockchain itself. This mechanism allows for a dynamic and transparent approach to managing fund freezes.
Networks on the Brink of Freezing Capabilities
As blockchain technology continues to evolve, 19 more networks are identified as having the potential to incorporate freezing capabilities with minimal changes. Particularly, the Cosmos ecosystem’s module accounts, which operate under module logic rather than through private keys, indicate how flexibility in a blockchain’s architecture can influence fund management and control.
The implications here reflect a technological tightrope: maintaining enough administrative control to safeguard assets against theft, while not tipping over into centralized control that could undermine user autonomy.
Decentralization vs. Centralization
Even as freezing mechanisms are designed to protect blockchain networks from malicious actors, they introduce a paradox concerning decentralization. Historically, decentralization has been lauded for its ability to distribute authority and enhance transparency. Yet, with the ability to seize control of funds, blockchain networks may inadvertently embody centralized features, casting shadows on their decentralized integrity.
The challenge lies in balancing these mechanisms with the core ideals of blockchain—where security enhancements should not compromise the freedom blockchain technology seeks to provide.
The Broader Conversation
Bybit’s report has elevated the conversation surrounding what it means to truly be decentralized. While protective measures against fraud and hacks are vital, the unintended consequences of embedding control functions within the blockchain stoke a debate that touches on censorship, user rights, and the philosophical underpinnings of blockchain technology.
In our increasingly digital world, where we rely on blockchain’s promise of trust and independence, the introduction of centralized control features may necessitate a reevaluation of these technological principles.
FAQ
What prompted Bybit to investigate blockchain freezing capabilities?
Bybit’s investigation was prompted by ongoing security concerns within its networks, heightened by past incidents like the $1.5 billion cold wallet hack. Their focus was on understanding how control features might enhance security yet affect decentralization.
How does freezing user funds impact blockchain decentralization?
Freezing user funds can shift power towards centralized authorities, potentially contradicting the decentralized ethos of blockchain technology. This power dynamic leads to a balance between needed security measures and preserving user autonomy.
Are all blockchain control mechanisms the same?
No, the mechanisms vary. Some are hardcoded, some use configuration files, and others employ onchain smart contracts. Each method reflects a different level of control and potential vulnerability within the blockchain’s infrastructure.
How might these findings affect future blockchain developments?
These findings may prompt developers and blockchain communities to reassess the integration of control mechanisms, striving for solutions that safeguard assets while maintaining the decentralized nature of the technology.
Is there an example of freezing capabilities being used positively?
In past incidents, like the Bybit hack, freezing capabilities helped recover exploited funds, showcasing how these functions can aid in security and asset protection. However, their use must be carefully considered to avoid centralization risks.

Coinbase Joins Prediction Market, AAVE Governance Dispute - What's the Overseas Crypto Community Talking About Today?
Over the past 24 hours, the crypto market has shown strong momentum across multiple dimensions. The mainstream discussion has focused on Coinbase's official entry into the prediction market through the acquisition of The Clearing Company, as well as the intense controversy within the AAVE community regarding token incentives and governance rights.
In terms of ecosystem development, Solana has introduced the innovative Kora fee layer aimed at reducing user transaction costs; meanwhile, the Perp DEX competition has intensified, with the showdown between Hyperliquid and Lighter sparking widespread community discussion on the future of decentralized derivatives.
This week, Coinbase announced the acquisition of The Clearing Company, marking another significant move to deepen its presence in this field after last week's announcement of launching a prediction market on its platform.
The Clearing Company's founder, Toni Gemayel, and the team will join Coinbase to jointly drive the development of the prediction market business.
Coinbase's Product Lead, Shan Aggarwal, stated that the growth of the prediction market is still in its early stages and predicts that 2026 will be the breakout year for this field.
The community has reacted positively to this, generally believing that Coinbase's entry will bring significant traffic and compliance advantages to the prediction market. However, this has also sparked discussions about the industry's competitive landscape.
Jai Bhavnani, Founder of Rivalry, commented that for startups, if their product model proves to be successful, industry giants like Coinbase have ample reason to replicate it.
This serves as a reminder to all entrepreneurs in the crypto space that they must build significant moats to withstand competition pressure from these giants.
Regulated prediction market platform Kalshi launched its research arm, Kalshi Research, this week, aimed at opening its internal data to the academic community and researchers to facilitate exploration of prediction market-related topics.
Its inaugural research report highlights Kalshi's outperformance in predicting inflation compared to Wall Street's traditional models. Kalshi co-founder Luana Lopes Lara commented that the power of prediction markets lies in the valuable data they generate, and it is now time to better utilize this data.
Meanwhile, Kalshi announced its support for the BNB Chain (BSC), allowing users to deposit and withdraw BNB and USDT via the BSC network.
This move is seen as a significant step for Kalshi to open its platform to a broader crypto user base, aiming to unlock access to the world's largest prediction market. Furthermore, Kalshi also revealed plans to host the first Prediction Market Summit in 2026 to further drive industry engagement and development.
The AAVE community recently engaged in heated debates around an Aave Improvement Proposal (AIP) titled "AAVE Tokenomics Alignment Phase One - Ownership Governance," aiming to transfer ownership and control of the Aave brand from Aave Labs to Aave DAO.
Aave founder Stani Kulechov publicly stated his intention to vote against the proposal, believing it oversimplifies the complex legal and operational structure, potentially slowing down the development process of core products like Aave V4.
The community's reaction was polarized. Some criticized Stani for adopting a "double standard" in governance and questioned whether his team had siphoned off protocol revenue, while others supported his cautious stance, arguing that significant governance changes require more thorough discussion.
This controversy highlights the tension between the ideal of DAO governance in DeFi projects and the actual power held by core development teams.
Despite governance disputes putting pressure on the AAVE token price, on-chain data shows that Stani Kulechov himself has purchased millions of dollars' worth of AAVE in the past few hours.
Simultaneously, a whale address, 0xDDC4, which had been quiet for 6 months, once again spent 500 ETH (approximately $1.53 million) to purchase 9,629 AAVE tokens. Data indicates that this whale has accumulated nearly 40,000 AAVE over the past year but is currently in an unrealized loss position.
The founder and whale's increased holdings during market volatility were interpreted by some investors as a confidence signal in AAVE's long-term value.
In this week's top article, Morpho Labs' "Curator Explained" detailed the role of "curators" in DeFi.
The article likened curators to asset managers in traditional finance, who design, deploy, and manage on-chain vaults, providing users with a one-click diversified investment portfolio.
Unlike traditional fund managers, DeFi curators execute strategies automatically through non-custodial smart contracts, allowing users to maintain full control of their assets. The article offered a new perspective on the specialization and risk management in the DeFi space.
Another widely circulated article, "Ethereum 2025: From Experiment to Global Infrastructure," provided a comprehensive summary of Ethereum's development over the past year. The article noted that 2025 is a crucial year for Ethereum's transition from an experimental project to global financial infrastructure. Through the Pectra and Fusaka hard forks, Ethereum achieved significant reductions in account abstraction and transaction costs.
Furthermore, the SEC's clarification of Ethereum's "non-securities" nature and the launch of tokenized funds on the Ethereum mainnet by traditional financial giants like JPMorgan marked Ethereum's gaining recognition from mainstream institutions. The article suggested that whether it is the continued growth of DeFi, the thriving L2 ecosystem, or the integration with the AI field, Ethereum's vision as the "world computer" is gradually becoming a reality.
The Solana Foundation engineering team released a fee layer solution called Kora this week.
Kora is a fee relayer and signatory node designed to provide the Solana ecosystem with a more flexible transaction fee payment method. Through Kora, users will be able to achieve gas-free transactions or choose to pay network fees using any stablecoin or SPL token. This innovation is seen as an important step in lowering the barrier of entry for new users and improving Solana network's availability.
Additionally, a deep research report on propAMM (proactive market maker) sparked community interest. The report's data analysis of propAMMs on Solana like HumidiFi indicated that Solana has achieved, or even surpassed, the level of transaction execution quality in traditional finance (TradFi) markets.
For example, on the SOL-USDC trading pair, HumidiFi is able to provide a highly competitive spread for large trades (0.4-1.6 bps), which is already better than the trading slippage of some mid-cap stocks in traditional markets.
Research suggests that propAMM is making the vision of the "Internet Capital Market" a reality, with Solana emerging as the prime venue for all of this to happen.
The competition in the perpetual contract DEX (Perp DEX) space is becoming increasingly heated.
In its latest official article, Hyperliquid has positioned its emerging competitor, Lighter, alongside centralized exchanges like Binance, referring to it as a platform utilizing a centralized sequencer. Hyperliquid emphasizes its transparency advantage of being "fully on-chain, operated by a validator network, and with no hidden state."
The community widely interprets this as Hyperliquid declaring "war" on Lighter. The technical differences between the two platforms have also become a focal point of discussion: Hyperliquid focuses on ultimate on-chain transparency, while Lighter emphasizes achieving "verifiable execution" through zero-knowledge proofs to provide users with a Central Limit Order Book (CLOB)-like trading experience.
This battle over the future direction of decentralized derivatives exchanges is expected to peak in 2026.
Meanwhile, discussions about Lighter's trading fees have surfaced. Some users have pointed out that Lighter charged as much as 81 basis points (0.81%) for a $2 million USD/JPY forex trade, far exceeding the near-zero spreads of traditional forex brokers.
Some argue that Lighter does not follow a B-book model that bets against market makers, instead anchoring its prices to the TradFi market, and the high fees may be related to the current liquidity or market maker balance incentives. Providing a more competitive spread for real-world assets (RWA) in the highly volatile crypto market is a key issue Lighter will need to address in the future.
