Four #cyphertots came through the house yesterday. They made physical keys which they protected the entire morning. They worked as a team to complete various word, mathematic and jungle gym challanges with their proof of work rewarded with new blocks and paper sats awarded randomly by the roll of a dice. They marked the paper blocks of their blockchain to account for the fresh sats. Then made their own fiat currency - because it's that easy to make. They all left smiling.

The future is bright #bitcoin #pow
