At the airport, Charles Hoskinson did a surprise AMA on March 24th that answered a few questions that Cardano fans had. The most important one was that Shelley is coming either this week or next week onto the testnet and that will mark the true beginning of the decentralization of the settlement layer in Cardano. He also mentioned that the coffee-bean project in Ethiopia is getting underway and that in that area, people actually have been using Cardano to transfer money. There were also details about the people Cardano were training in blockchain and programming in Africa and other developments they have. Not bad for an in-promptu AMA at the airport.
