# Ethereum Protocol Fellowship 6th week update

## Self Introduction
I’m a PhD student in Syracuse University in Blockchain security area, and now working on the Ethereum Mempool Attack Detection&Defence. Very excited joining in the fellowship and make some contribution to the Ethereum Portocol.

I have implemented DoS defense schemes on the latest Geth client (version 1.10.26), The defenses are extensively tested in our lab (controlled environment) and are secure against known DETER attacks.   Here is the link for the update: 
https://github.com/ethereum/go-ethereum/pull/26311/files.  
For now, I am under Marius's mentorship, 
> Marius is one of the contributors of Geth client. His modification is based on the code I updated:
https://github.com/MariusVanDerWijden/go-ethereum/tree/txpool-attacks

and he helped me review the code and make my modification more productive.
