Getting Started

1. Run nodes in separate terminals as ports in php in-built server 8080,8081,8082

Note: If you are using windows, you may need to run php development server individually for every port or you will get dying connections if you run php supervisor.php with the transactions.

php -S {host}:{port} index.php

Alternitively, you can run a docker container. Please see steps in bin/docker-setup

2. Add transactions to a node

http -f POST {host}:8080/add/trx sender="sam" recipient="max" amount="100"

3. View chain

http GET {host}:8080/chain

4. Mine chain

http GET {host}:8080/mine

5. Register nodes in different node

http GET {host}:8081/register/nodes <<<"{'nodes':['localhost:8080','localhost:8082']}"

OR

echo {'nodes':['localhost:8080','localhost:8082']} | http GET {host}:8081/register/nodes

6. View registered node

http GET {host}:8081/nodes

7. View chain on node 8081 first then do consensus

http GET {host}:8081/consensus

8. View chain on node 8081 again.
