Before Ethereum’s launch, the Russian-Canadian writer and programmer has been involved in the Bitcoin community since 2011. He co-founded Bitcoin magazine and wrote articles for the news magazine.
Recently, Ethereum moved from Proof of Work to Proof of Stake consensus mechanism. Called the Merge, the event can be the reason for the book's launch.
Vitalik Buterin tweeted about the book sharing the link for the Gitcoin website where it is possible to buy the book. The profits of the sale Buterin has committed to support open-source public goods through Gitcoin Grants.
