debate: is 51% of nodes need to check Ethereum transactions?
Ethereum, like most cryptomen, works on decentralized technology and open blockchain. However, the question if at least 51% of the nodes should check the transactions before adding new ones to the network caused a dispute between enthusiasts and experts.
The debate revolves around the concept of « validation of the majority », which means that at least half of all the nodes of the network must agree to include the blockchain transaction. This is often called a « 51%rule ». Theoretically, if there are more than 50% of the verifying transaction nodes, the network has reached an unstable condition and can have problems of scalability and safety.
Why a 51%rule?
The 51% rule was proposed for the first time by Vitalik Boterin, one of the Ethereum Co -Fondators, in their first blog post. He said that the network should be able to maintain its integrity and prevent spam or harmful behavior at risk of its value. According to the Bterina, if at least half of all the nodes verified the transactions before adding them to the blockchain, it would guarantee:
1.
2.
Call with a rule of 51%

However, the 51% rule has several disadvantages:
1
- Safety risks : a compromised node could potentially stop the entire network by flooding with false transactions, which would lead to the loss of trust in the blockchain.
- Restrictions of scalability : with over 50% of the nodes that verify transactions, the scalability of the network can suffer from an increase in the transaction verification time and greater energy consumption.
Current state of Ethereum
Since March 2023, Ethereum has been operating with about 75% of its knots participating in the validation. This is still below the majority of 51%. Although it is not yet fully fixed to a network without significant or improved adjustments, some experts say that the current situation is sufficient to maintain the integrity of the blockchain.
Conclusion
The debate about 51% of the rule triggered important discussions on the safety and decentralization of the network. However, since Ethereum is constantly evolving and expanding its network, it is necessary to consider the benefits against disadvantages. The validation rate currently introduced by the majority can be sufficient to maintain the integrity of the blockchain, but experts warn that significant improvements are needed to ensure long -term stability.
Ultimately, the 51% rule acts as a useful guide rather than an absolute requirement. When the Ethereum ecosystem continues to develop and mature, it decisive to monitor the performance of the network and adapt its validation processes if necessary to maintain the integrity of the blockchain.
