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.
这一轮的kickstart，第一题推了好久，才把large搞出来啊，后来才知道知乎上有讨论的了。。。这样下去要跪啊。。。
又是好久没写blog了。。。这周末要做kickstart，拿一个practice round练一练，发现这三道题还是挺简单的，主要很想记录一下B题Vote的，这个题和spoj上的INS14G - Kill them All是一样的思路，当初好不容易想明白，结果自己做的时候又有些忘记了。。。
好累啊，一年又一年，没有活成我想要的样子，没有去我想去的地方。
今年希望将自己的理想可以实现～
再不写blog估计这里就要长草了。。。最近自己在弄程序静态分析这块，提取相关的特征，IDA python 提取程序的操作码以及立即数。最近有面试通知，想了想还是要做LeetCode，于是在赶LeetCode的进度。。。LeetCode现在做到了200+左右，后面会陆续写LeetCode的总结。51nod四级题还差十几个，做完然后好好理一理思路。(都快忘了怎么写blog了。。。)
