The innovation of Ethereum: improvements to proof of stake

The world of cryptocurrencies is constantly evolving, with Ethereum (ETH) standing out as a pioneer in the field of proof of stake. 

Recently, ETH has recorded an increase of 6.77%, a positive signal for investors and industry enthusiasts.

This development can largely be attributed to the proposal by Vitalik Buterin, co-founder of Ethereum, to simplify the proof of stake (PoS) consensus mechanism of the platform.

The problem of complexity in Ethereum’s proof of stake

The heart of the matter lies in the intrinsic systemic complexity of Ethereum’s Proof of Stake (PoS) mechanism. Buterin has identified a critical node: the management of digital signatures. Validators, responsible for the network’s operation, must produce a high number of digital signatures.

This process, already burdensome, becomes even more burdensome with the increase of validators, leading to system overload. 

Future implementations could even further intensify the signing requirements. The challenge is therefore not only to maintain, but also to optimize efficiency in a constantly growing ecosystem. 

Addressing this issue is crucial to ensure the long-term scalability and sustainability of Ethereum.

The solution proposed by Buterin aims to simplify the process without sacrificing the security and integrity of the network.

Buterin’s three proposals to simplify the process

Buterin outlined three possible solutions at the Ethereum research forum on December 27th. The common focus of the proposals is to reduce the number of signatures required per slot to 8,192 in the Ethereum blockchain.

  1. Decentralized staking pools: The first solution proposes the introduction of decentralized staking pools. This would involve increasing the minimum amount of ether required to run a validator, encouraging operators to collaborate and pool their resources. This approach could not only lighten the workload of individual validators but also promote an atmosphere of cooperation and mutualism within the Ethereum network.
  2. two levels of stakers: The second solution involves creating two levels of stakers: one with more demanding requirements and the other with lighter requirements. These two levels would be treated differently in the block finalization process. This structure could provide greater flexibility and accessibility for different types of participants in the network, balancing security and inclusivity.
  3. Rotating participants: Finally, the third proposal suggests the adoption of a system of rotating participants, where a random set of validators is selected for each slot. This system would distribute the workload and reduce the total number of signatures, but it would add complexity to the system. This method could improve fairness and decentralization, ensuring a more even distribution of responsibilities and rewards among participants.


Buterin’s proposal represents a significant step towards a more efficient and effective implementation of the PoS mechanism in Ethereum. 

By reducing the complexity and workload of validators, Ethereum could achieve greater scalability and security. It is clear that the future of Ethereum, with its transition to the proof of stake model, still holds many innovations and potential improvements. 

In addition, this evolution highlights Ethereum’s ongoing commitment to finding solutions that not only improve network performance, but also contribute to greater decentralization and democracy in the world of cryptocurrencies. 

Buterin’s vision for a leaner and more robust system could prove crucial in the evolution of the cryptocurrency industry, marking an era of new possibilities and applications.
