Rosetta ステーキングのチュートリアル

このドキュメントでは、Rosetta API に関する Internet Computer の実装を使用して Neuron を作成する手順を説明します。ガバナンス Canister への資金移動、 Neuron を作成し、新しく作成された Neuron を設定します。

前提知識​

チュートリアルを完了するには、以下のものが必要です：

  1. 稼働中の Rosetta ノード、https://hub.docker.com/r/dfinity/rosetta-api から最新の docker イメージを使用できるようにします。このチュートリアルでは、Rosetta ノードが localhost:8080 というアドレスで動作していることを想定しています。

  2. curl

  3. ed25519 キーと、そのキーを使ってメッセージに署名するためのお気に入りのツール。

  4. あなたのキーで管理される台帳アカウントの少なくとも 2 ICP （Compute the ledger account for staking のセクションを参照してください）。

概要​

Internet Computer から見ると、 Neuron を作るのは多段階の操作になります。

  1. 台帳 Canister を呼び出して、ステークのためにガバナンス Canister にトークンを送金します。

  2. ガバナンスに送金を通知します。このステップで、ガバナンス Canister は新しい Neuron を割り当てます。

  3. 新しく作成された Neuron に対して、溶解遅延と溶解を開始する設定を行います。

Rosetta API では、これらのステップをトランザクションの operation として表現しています。これらの操作の実行は、Construction API flow に従わなければなりません。

アカウント識別子を導出する​

ステーキングには、ガバナンス Canister のサブアカウントへのトークンの送金が必要です。送金を完了するには、台帳のアカウント識別子（送金元）とガバナンスサブアカウント（送金先）のアカウント識別子の両方を知っておく必要があります。

エンドポイント /construction/derive を呼び出し、あなたの公開鍵で管理されているデフォルトの台帳アカウントと、その鍵で管理されている Neuron のアカウントを取得します。

ソース台帳アカウントを計算する​

note

以下のリクエストの hex_bytes をあなたの公開鍵のバイトに置き換えてください。

curl -0 -X POST http://localhost:8080/construction/derive \
  -H 'Content-Type: application/json; charset=utf-8' \
  --data-binary @- <<EOF
{
  "network_identifier": { "blockchain": "Internet Computer", "network": "00000000000000020101" },

    "curve_type": "edwards25519"
  }
}
EOF

期待されるレスポンスは次のようなものです：

{
  "account_identifier": {
    "address": "8af54f1fa09faeca18d294e0787346264f9f1d6189ed20ff14f029a160b787e8"

ステーキングのための台帳アカウントを計算する​

note

以下のリクエストの hex_bytes をあなたの公開鍵のバイトに置き換えてください。

curl -0 -X POST http://localhost:8080/construction/derive \
  -H 'Content-Type: application/json; charset=utf-8' \
  --data-binary @- <<EOF
{
  "network_identifier": { "blockchain": "Internet Computer", "network": "00000000000000020101" },
  "public_key": {

    "curve_type": "edwards25519"
  },
  "metadata": {
    "account_type": "neuron",
    "neuron_index": 0
  }
}
note

リクエストのメタデータで account_type を neuron に設定し、Rosetta ノードにステーキング用のアカウントを取得したいことを伝えます。neuron_indexパラメータは、呼び出し側が Neuron を識別するために選択した任意の64ビット符号なし整数です。一人のユーザーが複数の Neuron を制御することができ、neuron_index に異なる値を指定することでそれらを区別することができます。neuron_index はオプションで、デフォルトでは 0 に設定されています。

以下のようなレスポンスがあるはずです：

{
  "account_identifier": {
    "address": "92bfc8dd46076c46de4444f15afbb8f7a5050af240384a8a2d115b359f100fc6"
  }
}

署名するペイロードを取得する​

以下の点を注意してください：

  • 以下の address フィールドは、前のステップで取得したアドレスに置き換えてください。2 番目の TRANSACTION オペレーション（下のスニペットではインデックス 1） Nueron の台帳アドレスを使用する必要があります。それ以外の操作では、 Nueron のコントローラーの台帳アドレスを使用します。

  • TRANSACTION オペレーションの中の金額は、あなたがステークした金額です。この例では、金額は 1 ICP です。

  • SET_DISSOLVE_TIMESTAMP オペレーションの dissolve_time_utc_seconds メタデータフィールドを調整します。現在のタイムスタンプに31,557,600秒を加えたものが、1年分のステーキングに相当します。

  • すべての Nueron 管理操作は、オプションで neuron_index メタデータフィールドをサポートしています。neuron_indexには、Compute the ledger account for staking のステップで指定した値と同じ値を使用する必要があります。

note

レスポンスの payloads フィールドは、トランザクションを送信する前に署名される必要があるペイロードのリストを含みます。

note

Rosetta API 仕様書（Flow of Operations）によると、クライアントは /construction/preprocess と /construction/metadata をコールしてから /construction/payloads をコールすべきです。これは、ペイロードリクエストに添付すべきメタデータがある可能性があるためです。現在のところ、ICP Rosetta ノードの実装ではこれを行う必要がないため、これらの不要なステップをスキップしています。

署名しようとするトランザクションの内容を確認する​

トランザクションの内容をデコードするために /construction/parse エンドポイントを呼び出します。

note

下の transaction フィールドの値を、前のステップで取得した unsigned_transaction フィールドの値で置き換えます。signed フィールドは false に設定されていることに注意してください。

note
  • Neuron の管理操作は、Rosetta の仕様に厳密に従っているわけではありません。上のトランザクションを /block/transaction エンドポイントを使ってハッシュで調べると、台帳の送金しか含まれていないことになります。さらに、トランザクションに Nueron 管理操作しか含まれていない場合、返されるトランザクションのハッシュは台帳チェーン上に全く存在しないことになります。そのため、レスポンスの metadata フィールドには、 /block/transaction が返すのと同じフォーマットで、すべての操作のステータスが含まれます。
  • STAKE 操作は、ガバナンススマートコントラクトが作成した Nueron の一意な識別子を返します。この識別子を使用して、NNS Dapp または https://ic.rocks 上で Nueron を見つけることができます。

Neuron の状態を確認する​

それでは、新しく作成された Nueron の状態を確認してみましょう。

note

  • 以下の address フィールドは、ステップ Compute the ledger account for staking で取得した Nueron のアドレスに置き換えてください。

  • public_key.hex_bytes は、あなたの公開鍵の16進数（hex）で置き換えてください。
