• Spin up second node using yarn start2 (port 8334)

Connecting nodes

Use curl commands to connect node to each other:

# add node http://localhost:8334 to http://localhost:8333
curl -X POST http://localhost:8333/nodes/register \
  -H 'Content-Type: application/json' \
  -d '{ "host": "http://localhost:8334" }'

and vice versa:

add node http://localhost:8333 to http://localhost:8334
curl -X POST http://localhost:8334/nodes/register \
  -H 'Content-Type: application/json' \
  -d '{ "host": "http://localhost:8333" }'
