Personal site · London
I’m a crypto enthusiast, a long-term Bitcoin holder and I was passionate about smart contracts, Solidity auditing and competitive programming. I build and share what I learn along the way. I’m currently creating videos and sharing ideas on Twitter and YouTube.

I enjoy smart contracts and Solidity auditing. You can find my work on Code4rena and Sherlock.
For code and ongoing notes, visit GitHub and my progress reports.
I also share smart-contract lectures on Bilibili.
I love competitive programming. Here are my profiles and archives:
Beijing University of Posts and Telecommunications
Bachelor’s in Computer Science · 2011–2015
Master’s in Information Security · 2015–2018
While at university, I maintained a monthly life summary on CSDN and a Chinese writing archive here.
Those posts are older, but they remain part of the record.
Notes on engineering, security, algorithms, and life.
这一期10道题好难啊。。。好多要记的。
时维九月，序属三秋。然而，美好的九月都要过完啦。。。要做一做LeetCode上面的题啦，一直说要把这个做完，一直没有恒心做下去，马上十月了，一天三道，希望年底能把这些K完。昨天写日记的时候，又有一个日记本要写完了，然后就想起在家里的从七岁开始写下的十几个本子(好像到二十了？也不太清楚了)，突然莫名地觉得下一个本子是我人生的第二部了，希望下一部能够精彩吧。之前接触过一些acmer，其中好些人对LeetCode的态度是很鄙视的，觉得太简单。我对这些表示鄙视的人表示反鄙视，这里面的有些题过掉可能不难，但是在面试中，时常要求的是最低时间复杂度、空间复杂度，这样其实有些题(链表啊，各种STL的设计啊)很变态的，写的时候参考了很多discuss，还有csdn博客上面的内容。
