A number of Ethereum's liquid staking services have taken steps to enforce (or are in the process of incorporating) a voluntary constraint, mandating that these platforms do not exceed a 22% market share.

This proposition is aimed at safeguarding what some claim to be the diminishing decentralization of the network. However, not all stakeholders have embraced it wholeheartedly. Let's explore the origins of this particular percentage and assess the rationale behind such limitations.

Why the 22% rule?

The 22% figure originates from concerns about the centralization of Ethereum's liquid staking ecosystem. The idea is to prevent a single service or a small group of services from dominating the market, which could potentially compromise the network's decentralization and security. By limiting their market share to 22%, these services want to create a more balanced and robust ecosystem.

However, the response to this proposal is mixed. Some argue that it's a necessary measure to maintain Ethereum's core principles of decentralization and security. Others see it as an arbitrary restriction that could stifle competition and innovation in the liquid staking space.

The debate on whether such limitations are the right approach to address the centralization issue or if alternative solutions should be explored still continues. It remains to be seen how this initiative will impact the Ethereum ecosystem in the long run and whether it will indeed help preserve the network's decentralization.

Better safe than sorry

The 22% limit is proposed to prevent collusion. The idea was put forth by an Ethereum developer using the pseudonym Superphiz in May 2022.

He explained that to confirm a block in the network, you need the agreement of 66% of validators. Therefore, the 22% staking service limit means that at least four major platforms would have to conspire for a coordinated attack on the protocol. The question raised by the programmer is whether staking pools are willing to prioritize the well-being of the ecosystem over their own profits.

Based on the HashKey report, as of 2023, the collective market size of Liquid Stake Derivatives (LSD) has expanded to $22 billion, and the valuation of staking platforms has reached $18 billion.

The expansion of LSD protocols unquestionably benefits communities and token owners. Nevertheless, it also presents a potential danger to the integrity of the Ethereum blockchain. Staking services typically depend on a limited pool of node operators who manage a substantial number of validators. This scenario introduces notable decentralization risks to the network, as experts have outlined in the HashKey report.

Analysts highlighted the potential security threat, as large players could facilitate a 51% attack by malicious actors. Despite these ominous forecasts, HashKey recognized that most protocols have emerged relatively recently and have developed plans for decentralization and validator distribution.

This balance between the advantages and potential drawbacks of LSD protocols underscores the ongoing debate within the Ethereum community about how to strike the right balance between innovation and the preservation of decentralization and security in the network.

Is it a good idea? 

Superphiz has been advocating for limitations in the name of security for over a year, and it appears not without reason. He has paid significant attention to the largest Ethereum liquid staking service, Lido Finance (LDO).

Based on information available on the Dune at the moment of writing, Lido Finance controls 32.2% of the total staked ETH, while its nearest rival, Coinbase, commands just 8.1% of the market share. In July 2022, the Lido community nearly unanimously decided to forego self-imposed limitations. Nevertheless, when the protocol experienced a daily influx of 150,000 ETH, the developers implemented a daily limit mechanism on staking frequency. In the community have even appeared concerns that the protocol could potentially capture the necessary 66% for an attack.

To recap, in early August 2023, Lido reported a Total Value Locked (TVL) growth exceeding $15 billion. According to the developers, the service saw an influx of more than 10,000 new users in July.

Prior to this, Glassnode analysts had reported that after the activation of the Shanghai upgrade on the Ethereum network, there was an increased flow of coins into liquid staking protocols, with Lido Finance at the forefront.

The growth in TVL and user adoption of Lido Finance demonstrates the strong interest in Ethereum's liquid staking ecosystem. However, this success also brings questions and concerns regarding the potential centralization and security of the network, as highlighted by the discussions surrounding the imposed restrictions and their impact on the Ethereum blockchain's decentralization.

Conclusion

The discussions surrounding limitations in the Ethereum liquid staking space raise important questions about the balance between ecosystem growth and the preservation of network decentralization and security. The development of Liquid Stake Derivative protocols has garnered significant interest from the community and token holders, but it also creates concerns about potential centralization and security threats.

The initiative to limit market share to 22% represents a step towards ensuring the long-term sustainability of the network, yet it sparks debates and necessitates further analysis and discussion. As the Ethereum community continues to evolve, finding the right balance between innovation, user engagement, and security remains a pertinent challenge for developers and participants alike.
