The new book “Unresolved Issues of Web3” goes on sale today (February 29, 2024). It also includes material such as the Nikkei XTech paid article published on February 27, “The Fallacy of Decentralization”. It is available from Amazon and other retailers. A Kindle edition is also available.

Also, if you bring the print edition to BGIN Block #10 , which starts on Sunday, you may be able to get it signed by Professor Matsuo and me.

I hope you will pick up a copy.
