Implement RNG data provider #13

Open zlumer opened 6 years ago

zlumer commented 6 years ago

Random numbers can be used for:

Gambling.
Contests.
Other entropy.

We start with a simple RNG scheme:

roulette
slot machine
blackjack
lottery

Tasks

[ ] make a list of RNG data types: single number, set of numbers, verifiable set of numbers etc.
[ ] describe RNG workflow (random numbers are pushed in future blocks)
[ ] implement RNG oracle

Single random integer (-Infinity...+Infinity)
Multiple random integers in an array

Floats are not necessary: all floats can be represented as integers with decimal places. Verifiable numbers are temporary disabled.

https://github.com/willfrew/node-random-org https://github.com/rcombs/node-random Useful libraries, the second one is mentioned on random.org Both libs are based on JSON-RPC of the service, require api-key to use. The service has 2 releases of JSON-RPC, I'm not sure about which one is used in libs.

Current workflow/implementation: we assume, that random is "next-turn" request, so data request takes parameters (data id, from, to, memo; in future: amount), then the data is pushed by data publisher, saving memo.
