Lido Centralization Risk Assessment: Not as Serious as Imagined

As Ethereum transitions from a POW to a POS mechanism, Lido, as one of the main beneficiaries, has sparked attention and controversy within the Ethereum community due to its growing market share. Particularly as Lido refuses to “self-limit” and plans for further expansion, the discussions surrounding its perceived threats have become a current hot topic.

Some people are worried that the rise of Lido could undermine Ethereum’s decentralization characteristics, leading to node centralization and threatening network security. On the other hand, there are views that this concern is more of a marketing tactic aimed at slowing down Lido’s growth and allowing competitors to catch up. Both sides have their reasons.

This article will conduct an in-depth analysis of Lido’s market share and centralization risks, objectively assessing its impact on the decentralization and network security of Ethereum.

Lido Dominates Ethereum Staking, Raising Widespread Concerns

Lido is a project that addresses the issue of insufficient liquidity for staked tokens in PoS blockchains. In traditional staking, tokens are locked to secure the consensus mechanism, whereas Lido allows users to obtain tokenized versions of their deposited funds through liquid staking, enhancing staking liquidity.

Since its launch in 2020, Lido has become the preferred liquid staking platform for Ethereum 2.0 and other PoS public chains. Compared to the traditional minimum threshold of 32 ETH, Lido allows staking of any amount, lowering the barrier to entry. However, with rapid growth, concerns have begun to arise regarding its potential threat to the decentralization of Ethereum. Currently, Lido has staked 8,813,670 ETH, holding a 31.8% market share.

This has attracted the attention of Ethereum founder Vitalik. He has long suggested that all staking service providers limit their market share to below 15%, while Lido has far exceeded this limit.

There is a view that Lido operates more than 38% of validators, which is more than double what any single entity can control. This phenomenon of centralization has raised concerns about the centralization of Ethereum. Some researchers emphasize that Lido’s control over a large amount of staked Ether and its monopoly on the liquid staking market may face risks such as validator slashing, governance attacks, and smart contract vulnerabilities. Addressing the issue of Lido’s excessive market share is crucial for ensuring the decentralization and security of Ethereum.

The dangers of Lido centralization may be exaggerated

Although Lido is approaching the first security line of 33%, its decision to refuse self-restraint has raised questions. However, these concerns may overlook a key issue: the authenticity and completeness of market share information.

Lido, as a fully open and transparent on-chain protocol, has data that is real and credible. In contrast, some centralized exchange platforms ranked afterward may not disclose all adverse data. Therefore, the claim that Lido approaches 33% may be exaggerated.

Even if the data from all parties is accurate, Lido’s 33% market share is not as harmful as some people claim.

Understanding from two aspects: first, Lido allocates funds to 29 operators for staking, which diversifies the risk. Secondly, node operators have no malicious motives, as influencing the network would harm their own interests.

The biggest risk currently lies with the Lido designated node operators, which may lead to collusion of interests. However, Lido has strict standards in its selection process to ensure diversity and decentralization, and even if issues arise, the social layer can intervene to address them.

Lido Reflects the Centralization Issues of Ethereum

The situation with Lido can be seen as a manifestation of the centralization problem in Ethereum, and it may occur again in other projects in the future. Under community governance, members may be more inclined to choose directions that benefit themselves rather than the ecosystem.

The Lido community overwhelmingly voted against the cap proposal, reflecting the uncontrollable nature of complete decentralization. In fact, the trend toward centralization has raised concerns after Ethereum transitioned to POS, as large stakeholders may dominate the validation process.

In this regard, Lido is not the most serious. It is a “consortium” operated by multiple node operators, managed by a DAO to ensure diversity. In contrast, centralized exchange platforms may pose a greater threat to the decentralization of Ethereum.

The transition of Ethereum to PoS has brought advantages, but it has also raised concerns about centralization. The issues with Lido provide an opportunity to promote discussions among all parties on how to strike a balance between the advantages of PoS and the risks of centralization.

Potential Solutions to Lido Issues

To alleviate concerns, Lido can take several measures:

1. Consider self-limiting market share within a fixed time.
2. Improve the degree of internal decentralization
3. Take measures to fairly prevent system price fraud.
4. Increase the number of node operators to enhance diversity.
5. Build appropriate system safeguards and fulfill the responsibilities of a market leader.
6. Consider implementing a mechanism to automatically increase user fees when market share exceeds the target.

Through these measures, Lido can mitigate the impact on the decentralization of Ethereum, while alleviating concerns about excessive market share, helping to protect the stability and security of the entire ecosystem.

Conclusion

An interesting perspective on the controversy surrounding Lido is that without decentralized liquidity protocols like Lido, the staking market might be monopolized by centralized exchanges. This reminds us to consider multiple aspects of the market comprehensively, ensuring fair competition while also safeguarding the long-term development of the ecosystem.
