I feel like we are on the edge of a discovery that will mark a fundamental change in humanity. It is all at once exciting and terrifying. Like taking the men out of the missile silos, I fear that the blockchain moves us one step closer to Skynet becoming self aware. Math replaces human regulation.

for a block chain thing about cooking from straight run gradient you make a dish like coq a vjin with wine but you're starting with the grapes and going all the way from scratch. if something screws up along the way then you know it's broken so if the instead of wine you got vinegar when you had a cup of it to your coq you know that somethings wrong and you can instantly detect something was altered.
algorithms simply take input, do something and return output.
Think about converting Fahrenheit to Celsius or Celsius to Fahrenheit that would be an example of a basic algorithm. not all algorithms are reversable.
a hash is a complex mathematical operation that one performed on a bit of data will always give back that same hash for the same bit of data. usually they are one away so if you have a hash you can't figure out what data it represents even if you know the algorithm that was used
