This article mainly introduces "how to solve the Invalid Difficulty error of Geth synchronization". In the daily operation, I believe many people have doubts about how to solve the problem of Invalid Difficulty error of Geth synchronization. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt of "how to solve the Invalid Difficulty error of Geth synchronization". Next, please follow the editor to study!

You may encounter this invalid difficulty error when you use Geth to synchronize ethernet block chains:

WARN [03-01 | 11:17:41] Synchronisation failed, dropping peer peer=68677387327cf808 err= "retrieved hash chain is invalid" ERROR [03-01 | 11:17:58] # BAD BLOCK # Chain config: {ChainID: 1 Homestead: 1150000 DAO: 1920000 DAOSupport: true EIP150: 2463000 EIP155: 2675000 EIP158: 2675000 Byzantium: 4370000 Constantinople: Engine: ethash} Number: 7280000Hash: 0xeddb0590e1095fbe51205a51a297daef7259e229af0432214ae6cb2c1f750750Error: invalid difficulty: have 2957101900364072 Want 2958201410943272 # cause of failure

To quickly grasp the block chain and digital currency application development, Huizhi Network's block chain development series of online tutorials are recommended. The content covers a variety of mainstream blockchain platforms such as Bitcoin, ethernet, EOS, super ledger, Tendermint, etc., and supports Java, C#, Python, PHP, JavaScript, Dart and other development languages.

This is because the version of Geth used does not support Constantinople bifurcation (Constantinople Fork), such as Constantinople: in the error log above, or although a new version of Geth that supports Constantinople bifurcation is used, the local chunk chain contains chunks generated by the old version, resulting in synchronization failure.

Solution

If you are not using the latest version of Geth, you can upgrade to the latest stable version. Download address on the official website: Geth Releases.

If Geth has been upgraded to the latest version and the invalid difficulty error still occurs after startup, you can let Geth run for a while to reorganize local chunks, or empty the local blockchain data and resynchronize it from scratch.

At this point, the study on "how to solve Invalid Difficulty errors in Geth synchronization" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
