Started writing in 2017, dropped Core Ethereum, Korea’s first Ethereum tech book, in April 2018!  It became a go-to for blockchain classes, and I gave tons of talks. Since then, Ethereum’s got L2 for scalability, and rival L1 chains popped up. Korea tried with Klaytn, Luna/Terra, Wemix, and Luniverse, but they didn’t quite shine. Regulations? Sure. But I think it’s more about lacking bold faith in blockchain & crypto’s future.  Rooting for KLEVA AI to become Korea’s AI blockchain champ! Oh, it’s Children’s Day, but no kids around.  #Blockchain #Crypto #KLEVAAI
