Progress Report - January 2021


I post a progress report showing what I did and how my products performed each month. Last month’s report can be seen here.

What did I do

Productive Hours in January Hours worked on side-projects in January

I worked 103 productive on side projects hours last month.

To make these progress reports a bit more interesting, from now on I’ll post my favourite song, TV show, and article I read last month.

What was worked on

  • Did the Capture the Ether CTF challenges

  • Did the Ethernaut CTF challenges

  • Received a bug bounty for discovering a contract vulnerable to sandwich attacks

  • I’ve been reading up a lot on what’s currently happening in the Ethereum ecosystem. Really impressed by the work Starkware is doing with their Cairo programming language to write zero-knowledge proof programs. I’ve never seen this dual witness-creating-proofer / simple-verifier programming style before.

    A hint is a piece of python code, which contains instructions that only the prover sees and executes. From the point of view of the verifier, these hints do not exist.

  • Have also been reading a lot about MEV and flashbots.

  • Small blog update: include featured image headers on the actual blog post page instead of only on the index page.

Platform Growth


Sessions stayed at 6,287 on my website.

Website Traffic

Finally, I stuck to my bi-weekly schedule of releasing a blog post - great start into the year! I even wrote more than two posts this month.

  1. Damn Vulnerable DeFi Solutions
  2. Ethernaut
  3. Capture The Ether
  4. DeFi Sandwich Attacks


My twitter followers increased by 15 to 686.


Learn EOS Development

I sold 7 books last month.


I made 126 EOS last month using arbitrage trading.

What’s next

  • I’m looking forward to the Paradigm CTF on Friday, February 8th.
  • As always I have some cool ideas for innovative projects that I want to try 😃
