Abstract
Description
標準的なクライアント/サーバモデルでは、中央サーバは、大部分のリソースを管理し得る。これは、中央サーバに対する攻撃又はその障害が生じた場合に、中央サーバに格納された大部分のリソースが危険に晒され得ることを意味する。対照的に、分散モデルでは、リソースは参加ノード間で共有される(「分散される」)。この場合、全ての参加ノードの能力は利用されず、1つのサーバの障害が大部分のリソースを危険に晒すことはない。
従来よく知られているように、ブロックチェーンは、ビットコインプロトコルに基づくシステムに参加するネットワーク接続されたノード間で記憶容量が分散されるトランザクション型台帳である。各ビットコイントランザクションはネットワークにブロードキャストされ、トランザクションが確認され、次にブロックに集約される。ブロックは、次に、ブロックを複数の参加ノードに格納することにより、ブロックチェーンに含まれる。
以下の実施形態は具体的にビットコインプロトコルのP2SH(pay-to-script-hash)方法を使用するトランザクションを参照する場合があるが、本発明はブロックチェーンビットコインプロトコルと別の機能的に等価な方法を用いて実施されて良いことが理解される。
ここで、NumSigsは、トランザクションを解除するためにRedeemスクリプトを満たすために必要な有効署名の数「m」である。PubK1、PubK2、...、PubK15は、トランザクションを解除する署名に対応する公開鍵である(最大15個の公開鍵まで)。NumKeysは公開鍵の数「n」である。
コンピュータソフトウェアを保証するメタデータ(M)を決定する方法、装置、及びシステムが以下に記載される。
上述のように、方法100は、コンピュータソフトウェアに関連付けられたデータ(D1)を決定するステップ110を含む。データ(D1)を決定するステップ110は、ユーザ、ノード、又はデータストアからデータ(D1)を受信するステップを含んで良い。データ(D1)を決定するステップ110は、第1ノード3においてデータ(D1)を生成するステップを更に含んで良い。
上述のように、方法100は、コンピュータソフトウェアの第1ハッシュ値(H1)を決定するステップ120を更に含む。第1ハッシュ値(H1)を決定するステップ120は、ユーザから第1ハッシュ値(H1)を受信する、又はデータストアから第1ハッシュ値(H1)にアクセスするステップを含んで良い。第1ハッシュ値(H1)を決定するステップ120は、第1ノード3においてハッシュ値を計算するステップを更に含んで良い。
方法100は、データ(D1)及びコンピュータソフトウェアに基づき第2ハッシュ値(H2)を決定するステップ130を更に含む。
更なる例では、第2ハッシュ値(H2)は、データ(D1)とコンピュータソフトウェアの実行ファイル(又は実行ファイルのハッシュ)と追加情報又はコンピュータソフトウェアに関連するライセンスとの連結のハッシュに基づき決定されて良い。
別の例では、ライセンスはマークル(Merkle)木のトップハッシュ値であって良い。マークル木の一例は図4に示される。マークル木では、各ノードにおけるハッシュ値は、それら個々の「子」ノードのハッシュである。例えば、ハッシュ値Hash−A305は、2個の「子」ノード309及び311におけるハッシュ値のハッシュである。マークル木のトップハッシュ値、Hash−AB303は、マークル木の中の全部のハッシュ値を含むことが分かる。つまり、これは、木の最下部にある4枚の「葉」のハッシュ値であるA1 317、A2 319、B1 321、及びB2 323をキャプチャする。
方法100は、通信ネットワーク5を介して、データ(D1)、第1ハッシュ値(H1)、及び第2ハッシュ値(H2)を、分散ハッシュテーブル13のエントリへ送信するステップ140を更に含む。
DHT13の中のキー値ペアのキーであるべき第2ハッシュ値(H2)、及びキー値ペアの値であるべき第1ハッシュ値(H1)について、キー及び値は、DHYT13の任意の参加ノードへ送信される。
方法100は、第2ハッシュ値(H2)を有するメタデータ(M)を決定するステップ150を更に含む。メタデータ(M)を決定するステップ150は、ユーザ、ノード、又はデータストアからメタデータ(M)を受信するステップを含んで良い。メタデータ(M)は、例えば、P2P分散台帳(ブロックチェーン)14上のトランザクションのP2SHマルチシグネチャ第1Redeemスクリプト(RS1)の中の公開鍵のために利用可能な15個の場所のうちの1又は複数の含まれて良い。
メタデータ(M)は、P2SHマルチシグネチャRedeemスクリプト(RS1)の中の公開鍵のために利用可能な15個の場所のうちの1又は複数に埋め込まれて良い。例えば、Redeemスクリプト(RS1)は次の形式を取って良い。
ここで、Metadata1及びMetadata2は、それぞれ、Redeemスクリプトの中の公開鍵の場所を取り入れるメタデータを含み、PubK1及びPubK2は公開鍵である。言い換えると、メタデータは、暗号鍵が提供されるべき位置としてブロックチェーンプロトコルにより指定された位置において、Redeemスクリプトの中で提供されて良い。これは、基礎にあるブロックチェーンプロトコルに対するいかなる変更も伴わずに、メタデータがトランザクション(Tx)に組み込まれ得るという利点を提供する。
上述のように、Redeemスクリプトは、ビットコインプロトコルの標準的なP2SH方法におけるアウトプットスクリプトの一例であり、ユーザがどのようにトランザクションレコード内で指定された暗号通貨へのアクセスを得ることができるかを記述する。
ここで、OP_1はトランザクションを解除するために第1Redeemスクリプト(RS1)を満たすために必要な署名の数(「NumSigs」)を示し、OP_3はRedeemスクリプトの中の公開鍵の数(「NumKeys」)を示す。
ここで、Sig−VU1は第1ユーザ23の署名を示す。上述のスクリプトは、第1暗号通貨額(C1)を解除するために、エージェント(A)又は第1ユーザ23からの1つの署名だけが必要であることを想定していることに留意する。
<第2Redeemスクリプト>
コンピュータソフトウェア及びライセンスに関連付けられたトークンは、エージェント(A)から別のユーザ、例えば第1ユーザ23又は第2ユーザ24へ転送されて良い。一例では、トークンの転送はコンピュータソフトウェア又はライセンスのユーザへのアクセスを許可することと同様であって良い。転送は第2Redeemスクリプト(RS2)により実施されて良い。
本例では、第2Redeemスクリプト(RS2)は、第1Redeemスクリプト(RS1)と同じ2個のメタデータフィールドを含む。第2Redeemスクリプト(RS2)は、エージェント(A)に関連付けられたエージェント公開鍵(PA)、及び第1ユーザに関連付けられた第1ユーザ公開鍵(PU1)を更に有する。
上述のように、データ(D1)又はライセンスは、それぞれコンピュータソフトウェア又はライセンスの位置を示す識別子を有して良い。
上述のように、第1ノード3及び第2ノード7は、コンピュータ、電話機、タブレットコンピュータ、モバイル通信装置、コンピュータサーバ、等のような電子装置であって良い。電子装置は、処理装置21、27、データストア17、及びユーザインタフェース15を含んで良い。
