You can also pass in "blocks" to get real-time block data over websockets
let socket = new bitbox.Socket({
callback: () => {
console.log("connected")
},
restURL: "http://localhost:3000"
})
socket.listen("transactions", message => {
console.log(message)
})
socket.listen("blocks", message => {
console.log(message)
})
