In simple words, proof of work means:
I solemnly announce a contest to find a number, which when you insert at the end of the accounting page and you hash this edited page, the resulting hash will begin with twenty zeroes.
In abstraction:
- a "contest" is the proof of work
- an "accounting page" is a block of the blockchain
- a "number" is the nonce
This project produces an example of the proof of work algorithm.
- Python 3
- Multicore CPU is recommended
usage: main.py [OPTION]
This is a program, that demonstrates an example of proof of work algorithm, with parallel execution.
optional arguments:
-p, --processes an integer, specify the number of processes;
default 1
-d, --difficulty an integer, specify proof of work difficulty;
in this case, it is count of zeroes at the start of the wanted hash;
default 4
--help display this help and exit
Exit status:
0 if OK,
1 if some problems
