Ethereum: Can Someone With 51% of the Computing Power Earn More Than They Deserve?

The debate over the 51% rule on Ethereum has been going on since the project’s inception. The 51% rule refers to the ability of a powerful group of miners to control more than 50% of the network’s mining power, potentially leading to an attack on the network. But can someone with 51% of the computing power earn more than they deserve?

The Problem with 51% Power

When a miner controls more than 50% of the network’s mining power, they become the dominant force in the network’s consensus mechanism. This can give them a significant advantage over other miners and users. For example, if a group of powerful miners were to attack a node on the network, they could potentially control more than 50% of the hashing power, allowing them to manipulate block rewards and transaction fees.

A Case for 51% Power

Supporters of the 51% rule argue that it is essential to protect the network from centralization and ensure that all miners have an equal say in decision-making. By limiting the number of miners to 51% power, they argue that the network will be more resilient to attacks.

However, critics argue that the 51% rule is too restrictive and could lead to censorship and unfairness on the network. They point out that a group of influential miners could simply opt out of the majority decision-making process or use their collective power to manipulate transactions without affecting others.

Ethereum 51% Rule

In February 2021, Ethereum updated its protocol to include a hard fork to prevent exactly this scenario from occurring. The new rule limits miners to holding more than 1 million ETH (about $5.7 billion at the time) in their wallets, significantly less than the original 2 million ETH required to secure the network.

While the new rule provides some protection against centralization, it does not eliminate the risk entirely. A group of powerful miners could still attempt to manipulate the network through other means, such as exploiting bugs or using their collective power to control more than 50%.

However, the new rule significantly reduces the likelihood that a miner will attempt to exploit these vulnerabilities.

Conclusion

In conclusion, while someone with 51% of the computing power can potentially earn more than they deserve if they are not careful, it is unlikely that they will be able to do so without facing significant risks and consequences. The new rule provided by Ethereum aims to mitigate these risks and protect the network from centralization, but there are still concerns about its effectiveness.

Ultimately, the debate over 51% power is still ongoing, with supporters and opponents making valid arguments on both sides. As the ecosystem continues to evolve, it will be interesting to see how this issue is addressed in the future.
