Introducing hcoin - a non scalable fictional currency . ICO soon to come ;)
All system users start with a balance of 0. Then for each transaction they either give out hcoins to other users (in this case they have their balance decreased), or they accept hcoins (in this case they have their balance increased)
Transactions have the following format:
2017-11-11,maria,nikos,54
2017-12-24,nikos,insurance,88
which translate to:
date,transaction_sender,transaction_receiver,amount
- user current balance need be available but also balance for a specific time in the past.
- users are identified through a username
- initial balance for all users is zero
- amounts are integers, and a limit is specified - currently this is 100
- transactions might occur every day but this is not necessary. there might be days with no transactions
- a user can send/receive amounts within the same day
No need to install anything, only need python2 or python3.
Clone the repository:
user@user:/tmp$ git clone https://github.com/mgogoulos/hcoin
user@user:/tmp$ cd hcoin
and run hcoin.py, this will get you some examples:
user@user:/tmp/hcoin$ python hcoin.py
hcoin show balance
Usage: hcoin.py all - will output balance for all users
Usage: hcoin.py user - will output balance for user
Usage: hcoin.py user date - will output balance for user, for that date
Example: hcoin.py user 2017-01-04 - will output balance for user, for that date
If you run hcoin with the transactions.txt included you will get the following output
Get balance for all users:
user@user:/tmp/hcoin$ python hcoin.py all

Use gen_transactions.py file, after editing default variables. There's plenty of documentation to direct you:
user@user:/tmp/hcoin$ python gen_transactions.py
total transactions generated: 11525
user@user:/tmp/MARKOS/hcoin$ head transactions.txt

To run the tests install pytest lib, either globally or inside a virtualenv.
Currently pytest is the only dependency on requirements.txt:
user@user:/tmp/hcoin$ virtualenv .
user@user:/tmp/hcoin$ ./bin/pip install -r requirements.txt
user@user:/tmp/hcoin$ ./bin/pytest tests.py
