API Blockchain per determinare le conferme delle transazioni

Question

Sto cercando di identificare se una transazione nella blockchain bitcoin è stata confermata o meno. Ho accede una rappresentazione JSON della transazione da blockchain.info utilizzando questo URL: https://blockchain.info/tx/62f9419e56ac1b628840aaf52307867f9856d7a52b3c1d945a9938a3021cbf2c?show_adv=false&format=json

non riesco a trovare nulla nella risposta che indica quante conferme ha ...

Answer 1

Il concetto di la "conferma" su Bitcoin si traduce essenzialmente in quanti blocchi sono stati generati dal blocco contenente la transazione. In altre parole, dovrai inviare un'altra richiesta per ottenere il numero corrente di blocchi di rete (http://blockchain.info/q/getblockcount) e il conteggio di conferma diventa current_block_count - transaction_block_height + 1. Si noti che block_height è presente solo nella risposta se almeno un blocco è stato generato poiché (ad esempio, le nuove transazioni potrebbero non includere nemmeno l'elemento).
