Vitalik Buterin is, without a doubt, the single most important human being in the global blockchain community. He's the co-founder of Ethereum and was recently named one of the 100 most influential people of 2021. You will hear a lot about Vitalik in future 3Blocks issues. For today, though, I wanted to point you to his excellent blog: vitalik.ca. His articles are admittedly quite technical, but there truly is no better resource for you to stay up to date with the latest Ethereum core development.
