I have to admit I haven't dug much into the actual blockchain except using SteemWorld by @steemchiller but that's basically it. The basic understanding of the Blockchain I understand but to really utilize and dig deeper to draw information from it, I don't. But this weeks @sndbox challenge is to dig into the blockchain and find out about your blockchain neighbors using SteemdB.
Going to publish it now and find this post on the blockchain and start exploring, find the results via the comments.
