Cuckoo Cycle

Go implementation

This is a Go implementation of the cuckoo Proof of Work algorith "cuckoo cycle" by John Tromp. This implementation includes the verification function as a library, and a simple multi-threaded miner.

Installation

To install this miner just run go get github.com/ZiRo-/cuckgo/miner

Usage

Usage of miner:
  -e float
    	easiness in percentage (default 50)
  -m int
    	maximum number of solutions (default 8)
  -t int
    	number of miner threads (default 4)

Algorithm

For details about the algorith, see: https://github.com/tromp/cuckoo

Benchmarks

N = 100, Easiness = 55, Average time = 0.9 s, CPU = i5-4210U

![N = 100, Easiness = 55, Average time = 0.9 s, CPU = i5-4210U] (https://raw.githubusercontent.com/ZiRo-/cuckgo/master/bench/bench_N_100_e_55_avg_0.9.png)

N = 100, Easiness = 50, Average time = 2.3 s, CPU = i5-4210U

![N = 100, Easiness = 50, Average time = 2.3 s, CPU = i5-4210U] (https://raw.githubusercontent.com/ZiRo-/cuckgo/master/bench/bench_N_100_e_50_avg_2.3.png)

N = 300, Easiness = 46, Average time = 56.2 s, CPU = i5-4210U

![N = 300, Easiness = 46, Average time = 56.2 s, CPU = i5-4210U] (https://raw.githubusercontent.com/ZiRo-/cuckgo/master/bench/bench_N_300_e_46_avg_56.2.png)

JavaScript version

Using GopherJS the Go implementation can be transpiled to JavaScript, which is also included in this repo. This file currently exports one function: cuckoo["mine_cuckoo"](easiness) which returns the same base64 representation of a proof as the Go CLI miner.
