The description and demonstration of the project you can find here..https://youtu.be/I1hJeWZlOQQ
in future i will extend this project to
1.real payment transaction along with keeping UTXO model.
2.smart contracts.
3.central bank digital currency model.
steps to run the project
step1:
clone the repository:
command:
$ git clone https://github.com/AVSAIKUMARREDDY/Complete-Blockchain-with-python.git
step2:
navigate to the directory
$ cd Complete-Blockchain-with-python
step3:
install basic utilities required to run the appcation
$ pip install -r requirements.txt
step4:
Start a blockchain node server,
$ export FLASK_APP=node_server.py
$ flask run --port 8000
step5:
also run 2 more servers ,take the new shell and run
$ export FLASK_APP=node_server.py
$ flask run --port 8001
now the server will be running at 8001
take the shell again and run
$ export FLASK_APP=node_server.py
$ flask run --port 8002
now total 3 servers are runinng the main one is at 8000 and other peers at 8001,8002
step6:
run the application
$ python3 run_app.py
now you can see the applcation running at port 5000 in your local address.
through client application you can submit transactions.
1.before submiting you need to run the key_gen.py to create private and public keys save both the keys and
2.sign the messge with the sign_it.py program here change the msg variable field to your desired message and in the place of string prv keep the priavte \ key and run the program and save the digital signature so that you can use this in the signature field in client application.
Join the nodes with each other
step7:
register 8001 with 8000
$ curl -X POST http://127.0.0.1:8001/register_with -H 'Content-Type: application/json' -d '{"node_address": "http://127.0.0.1:8000"}'
register 8002 with 8000
$ curl -X POST http://127.0.0.1:8002/register_with -H 'Content-Type: application/json' -d '{"node_address": "http://127.0.0.1:8000"}'
step8:
you can check the chain status by
$ curl -X GET http://localhost:8001/chain
$ curl -X GET http://localhost:8002/chain
or
in your browser type
http:/localhost:80001/chain
http://localhost:8002/chain

all the above commands will work for linux and macOs. If you are a windows user kindly check im not sure.
