I was fortunate to see something about Steemit shortly after it first started paying out, 2 or 3 months after launch. So I’d probably be “second wave” I guess!
I’ll have to dig around and see if I can find any good resources. Certainly reading the 2 white papers and blue paper you can find in the side navigation is a good start. But if you have an understanding of bitcoin and blockchain in general, you’re ahead of the game!
Steem works the same but instead of just storing financial transactions, it also stores text. Every post & comment we make goes into a block that is created once every 3 seconds. As such it’s important to remember that anything we post here is forever! You can’t completely erase anything recorded to Steem. Images and video are not stored on the blockchain. They’re too big to keep the blockchain manageable. They’re linked to by the blockchain, either hosted on a centralized server or using emerging decentralized file technology known as IPFS (which dTube is based off of.)
