Bitcoins require many gigawatts of electricity for mining, and so does the blockchain.
Aren't there much cheaper alternatives to solving mathematical equations, which use chaos?
For example, Sunspot patterns are a fingerprint of chaos and globally verifiable. If everyone on the chain uploads a 50kb cellphone photo twice a day... The total of that data would have the unpredictability of physical chaos. Isn't there a convenient chaos signal which is globally verifiable and which is better for allocating money and tasks than mining?
Apologies for being vague. I will try to clarify:
peer money and accounts nodes can be given a lottery ticket number as a pseudo random function based on a previous chaos result, ranging from 0 to 10^256.
Every hour the miners of the world return their collective measurement of a globally generated chaos signals, which returns a random number from 0 to 10^256, and the closest miner's ticket is recognized by all as the winner.
The winner gives his version of unverified transactions including transaction times and the time corresponding to the block challenge in a hash which includes sha-256 of all the previous blocks that have been tallied.
It would help me to understand hash contests, to know why the digital encryption wouldn't benefit from simply choosing a miner at random using tallied measurements of chaos from the cosmos or from global weather and so forth.
