My name is Fengjun Chen. I live in Shanghai, China. I get my master degree from Shanghai Jiao Tong University (the Top3 university in China) in 2019, majoring in CS with blockchain & security as research direction. I have published the paper _[Secure Scheme Against Compromised Hash in Proof-of-Work Blockchain](https://link.springer.com/chapter/10.1007/978-3-030-02744-5_1)_ on conference NSS 2018. I am competitive in the research of cryptography and cutting-edge blockchain techlonogy due to my academic experience. After leaving from campus, I joined [Cryptape](https://cryptape.com/#/home), an old-fashion blockchain company in China.
