XRPレジャーとは

XRPレジャーはBitcoinやEthereumなどと同じ分散型のパブリックブロックチェーンです。ビットコインの初期コントリビュータを含む3人の開発者により2012年に開発され、PoWやPoSとは異なる独自のコンセンサスアルゴリズムが用いられています。

XRPレジャーのNFT

2022年10月にXRPレジャーメインネットにてバリデータによるオンレジャーのガバナンス投票の結果、NFT機能が利用可能になりました。
NFTの発行や売買に必要となる手数料が低く(0.00001XRP=0.001円程度)、売買に伴うロイヤリティに強制力があることが大きな特徴です。

利用可能なNFT API

XRPL NFTの情報を取得するためのAPIはさまざまな方法が存在します。本記事ではそのうちのいくつかを紹介します。

利用可能なAPIには次のようなものが存在します。

  • XRPLのコアサーバであるrippledから直接取得
  • XRPLのAPIサーバであるClioから取得
  • サードパーティサービスのAPIから取得

rippledやClioから取得する場合は独自のサーバを利用することでレート制限などを回避することができますが、サードパーティAPIを利用する場合はレート制限などが存在することがあります。
