• http://localhost:5000/nodes/register --- To register a new node to P2P network

• http://localhost:5000/nodes/resolve --- To check for the longest chain and resolve your node's chain

• To send a transaction use Curl like the following example

$ curl -X POST -H "Content-Type: application/json" -d '{
 "sender": "d4ee26eee15148ee92c6cd394edd974e",
