understanding of the mining error ethereum: “The outdated or foreign proof of work”

As a developer Bitcoin and Ethereum, you are probably alien to the challenges of cryptocurrency mining. However, when an error message appears that indicates “outdated or extraterrestrial work tests”, it can be frustrating and disturbing. In this article, we immense what happens and we provide information about solving the problem.

What is the proof of work?

In Cryptocurrency mining, the work certificate (POW) is a consensual algorithm used to validate transactions and create new blocks. This includes a solution to a complex mathematical puzzle that requires a significant calculation. The miner who solves the puzzle first adds the new block to the blockchain and rewards it with a new cryptocurrency -without problems.

The question is: outdated or extraterrestrial work

When the server says “outdated” in his message of error, this means that his mining efforts do not bring new blocks at a sufficient rate. This can happen for several reasons:

• Incorrect difficulty settings : If the difficulty level has increased from the last update to the latest version, it can invalidate an older certificate of work solutions.

• Software of outdated clients : It is unlikely to be optimized for newer Ethereum versions, which will lead to performance problems and an “outdated” error.

• High calculation load : If GPU is able to reduce at high speed, but exceed the server capacity restrictions, the older certificate of work solutions can be invalid.

Work is a foreign proof

In addition to being “outdated”, the error message also suggests that it can be a foreigner (ie foreign or non-eTreum related to the work solution. This can happen when a malicious actor tries to minimize cryptocurrency Using another algorithm, which your client does not know as legitimate.

Solutions and solutions

To solve the problem, try the following steps:

• Update the Bitminte customer : Make sure you run the latest version of Bitminte V1.3.2 or newer version.

• Disable compression : Try to turn compression on the mining pool files to see, solve the problem.

• Restore customer settings : Return the latest changes to customer settings and try again with default configurations.

• Update GPU drivers : Make sure the graphic drivers are updated, because older versions can cause performance problems.

• Change the difficulty levels : If you suspect that the difficulty level increases the problem, consider updating a new version of the Bitminte customer or manual setting of difficulty settings.

Conclusion

The “evidence of the outdated or foreign work” can be caused by various factors, including the outdated customer software, the high calculation task and the malicious attempts of mining algorithms for cryptocurrency mining. Understanding what is happening behind the scenes and implementing these solutions, you must be able to solve the problem and continue to exploit Ethereum.
