トランザクション確認を行うためのブロックチェーンAPI

Question

ビットコインブロックチェーンのトランザクションが確認されたかどうかを確認しようとしています。私はこのURLを使ってblockchain.infoから取引のJSON表現にアクセスした：https://blockchain.info/tx/62f9419e56ac1b628840aaf52307867f9856d7a52b3c1d945a9938a3021cbf2c?show_adv=false&format=json

私はそれが持っているどのように多くの確認を示す応答で何かを見つけることができません...

Answer 1

の概念Bitcoinの「確認」は、基本的に、トランザクションを含むブロック以降に生成されたブロック数に変換されます。つまり、現在のネットワークブロック数（http://blockchain.info/q/getblockcount）を取得するために別のリクエストを発行する必要があります。その場合、確認カウントはcurrent_block_count - transaction_block_height + 1になります。少なくとも1つのブロックが生成された（つまり、新しいトランザクションに要素が含まれていなくても）場合、block_heightは応答にのみ存在することに注意してください。
