Based on Eric Traub tutorial

• api/blockchain : get, gets the blockchain
• api/transaction/broadcast: post, posts a transaction to be broadcasted. Returns status code 200 if successful
• api/transaction:
  • post . Posts transaction to be added to the pending transactions.
  • get ?id = . Gets transaction details
• api/register_and_broadcast_node : post, Posts the new node to be added and broadcasred
• api/register_node: post, Registers new node
• api/register_bulk: post, Registers new node
• api/mine: get, Mine a new, include the pending transactions in it.
• api/receive_new_block: post, Register new block in the chain.
• api/consensus: get, Gets the chain consensus. Node chain is updated if different than consensus.
• api/block: get ?hash = . Gets block details
• api/address: get ?address = . Gets transactions and balance for the specified address.

index.html demonstrates search (Block, Transaction, Address).

• Start 5 network nodes, listening on ports 3001 to 3005
  • npm run node_1
  • npm run node_2
  • npm run node_3
  • npm run node_4
  • npm run node_5
• Postman, register network nodes
  • localhost:3001/api/register_and_broadcast_node , payload {"newNode":"localhost:3002"}
  • localhost:3001/api/register_and_broadcast_node , payload {"newNode":"localhost:3003"}
  • localhost:3001/api/register_and_broadcast_node , payload {"newNode":"localhost:3004"}
  • localhost:3001/api/register_and_broadcast_node , payload {"newNode":"localhost:3005"}
• Postman, Broadcast transactions e.g.
  • localhost:3001/api/register_and_broadcast_node, payload {"amount": 100, "sender":"me", "recipient":"mkjhe"}
• Postman, mine new block
  • localhost:3001/api/mine
• Browser localhost:3002 and play
• Stop and restart a node e.g. node_5. Then get consensus from that node
  • localhost:3005/api/cosensus
