Notify every new ledger

Question

How I can get notify (like newblockinfo in bitcoin or getlastblock in ethereum or bitcoin) on new ledger in blockchain with go-sdk

Answer 1

Just use Client.StreamLedgers method:

client := DefaultPublicNetClient
cursor := Cursor("now")

// Call `cancel()` to stop streaming
ctx, cancel := context.WithCancel(context.Background())

err := client.StreamLedgers(ctx, &cursor, func(l Ledger) {
    fmt.Println(l.Sequence)
})

if err != nil {
    fmt.Println(err)
}
