    chaOS41

    A cryptocurrency like Bitcoin improved upon with reality binding.

    There is a reason this project holds no code. chaOS41 is a cryptocurrency with reality binding. A given value of money was paid for a surface area the size of a flower pot. It was out of proportion. The chaoOS41 currency corrects that. It binds its value to reality. Its unit value is a ratio between money and land area.. When that ratio normalizes, the currency becomes available to the public. 1 more developer is wanted. For that you need inside access, which means the access protocol is made public now. It is also the open-source cryptographic protocol. Type in a formatted string as "beacon" and a number. Repeat. When the identical string is produced, prepare. When the identical string repeats, a name is added. This signals that the next line of text you type, is registered. Hint: include a URL.End of protocol. Valid beacon digits are 250, 1024, 2048, 4096, 8192, 16384, 32768 and up.
