A huge set of YouTube videos were just uploaded to the Chia Network official channel covering all the basics of ChiaLisp programming. I presume this is the first of more that will come, including webinars and the Zoom meetings.
These training videos are meant both to help kickstart the ChiaLisp developer ecosystem in order to get DeFi and other on-chain distributed applications implemented in their blockchain, but also to help prepare people for the upcoming Chia Hackathon with Sirius Labs.
I don’t want to be accused of anything untoward, since they are on a bit of a tear, so I won’t embed any of the videos here but check them out here if you plan on competing in the hackathon.
