Answer 1

Koncepcja "potwierdzenie" na bitcoinie zasadniczo tłumaczy, ile bloków zostało wygenerowanych od bloku zawierającego transakcję. Innymi słowy, będziesz musiał wydać kolejną prośbę o pobranie aktualnej liczby bloków sieci (http://blockchain.info/q/getblockcount), a liczba potwierdzeń stanie się current_block_count - transaction_block_height + 1. Zauważ, że block_height występuje tylko w odpowiedzi, jeśli utworzono co najmniej jeden blok (tj. Nowe transakcje mogą nawet nie zawierać tego elementu).
