Ethical dilemma of work proof: The way the miners and knots can get rid of the fact that they have not reported blocking time

Being the largest cryptocurrency in the world by market capitalization, Ethereum has faced numerous challenges in maintaining the integrity of his blockchain network. One of the most significant concerns is the problem of validating evidence of work (POW), which is based on a complex algorithm that requires miners and knots to check the time when a block was extracted. While Pow offers a validators stimulant to provide the network by solving a difficult mathematical puzzle, it also creates opportunities for dishonest actors to manipulate data.

The problem with non -observance of the minimum time block

In the Bitcoin system, the proof of work, each block is checked in response to a specific metric of “locking time”. This is calculated by mediating the time elapsed between the last 20,000 blocks (approximately 2000 blocks). By setting this average at 10 minutes, the consensus protocol ensures that it takes about 10 minutes for a new block to be added and validated on blockchain. However, some nodes and miners have been known to manipulate this process by intentionally delaying or accelerating the time between blocks.

The consequences of the node fudging

When the nodes fail to report their minimum block accurately, they can lead to multiple consequences:

• Incorrect chain data : Nodes that misplace time will create an inclined view of blockchain history, which makes it difficult for other knots and users to check for transactions or access the relevant data.

• The network segregation : Incorrect reporting of time can determine the nodes with different opinions regarding the time of the block to be separated from each other. This can lead to loss of confidence among interested parties and may undermine network security.

• Inefficient network performance

  

  : Wrong reporting times can lead to delays or blockages in periods with high traffic, because nodes can give priority to their own accuracy, rather than blockchain status.

Ethereum’s unique challenges

While other cryptocurrencies are facing similar problems, Ethereum has made measures to alleviate these problems. The Ethereum network uses a “gas-based” consensus protocol, which stimulates the validators by rewarding them for their work in validating transactions and maintaining blockchain. However, this system is vulnerable to centralization and manipulation.

To solve these issues, several solutions have been proposed:

• Reporting improved time : In 2017, Ethereum implemented a consensus protocol “based on Timstamp”, which requires validators to report mined block hours based on its own observation of the block.

• Randomized synchronization of time : This solution involves random introduction in the time reporting process to prevent data manipulation.

Conclusion

The problem of validating the proof of work and the precise reporting of the time is a complex problem that requires careful examination of the basic mechanics. While Ethereum has done measures to address these challenges, more work should be done to ensure the integrity of his blockchain network. As the world becomes more and more dependent on decentralized systems, it is essential to give priority to transparency, security and responsibility in developing and implementing cryptocurrency protocols.
