多重署名の作成  (4)

トランザクションの作成  (1)

全関係者が鍵のペアを生成する必要がある．これらの鍵を組み合せて新しい多重署名アドレスを作成する：

Wolfram Language code: keys1 = GenerateAsymmetricKeyPair["ARK"]
Wolfram Language code: keys2 = GenerateAsymmetricKeyPair["ARK"]
Wolfram Language code: keys3 = GenerateAsymmetricKeyPair["ARK"]

口座残高が十分にある送信者は公開鍵を提供しなければならない：

Wolfram Language code: senderPublicKey = BlockchainAddressData["DNeJSpEqKBy3oJ5MXrfuchwWj5a4JXxTQp", "PublicKey", BlockchainBase -> {"ARK", "Devnet"}]
Wolfram Language code: arkTX = BlockchainTransaction[<| "BlockchainBase" -> {"ARK", "Devnet"}, "Type" -> "MultiSignature", "MinimumKeys" -> 2, "PublicKeys" -> {keys1["PublicKey"], keys2["PublicKey"], keys3["PublicKey"]}, "SenderPublicKey" -> senderPublicKey |>]

同時署名  (1)

ARKトランザクションに署名して多重署名のアドレスを作る．トランザクションにはすべての参加者が秘密鍵で署名しなければならない：

Wolfram Language code: arkTXMS = BlockchainTransactionSign[arkTX, { <|"PrivateKey" -> keys1["PrivateKey"]|>, <|"PrivateKey" -> keys2["PrivateKey"]|>, <|"PrivateKey" -> keys3["PrivateKey"]|> }]

連続署名  (1)

トランザクションオブジェクトに各参加者が連続的に署名することもできる：

Wolfram Language code: arkTXMS0 = BlockchainTransactionSign[arkTX, { <|"PrivateKey" -> keys1["PrivateKey"]|> }]
Wolfram Language code: arkTXMS1 = BlockchainTransactionSign[arkTXMS0, { <|"PrivateKey" -> keys2["PrivateKey"]|> }]
Wolfram Language code: arkTXMS2 = BlockchainTransactionSign[arkTXMS1, { <|"PrivateKey" -> keys3["PrivateKey"]|> }]

どちらの署名方法も等価である．

送信者の署名  (1)

トランザクションには送信者の署名も必要である．署名は，トランザクションオブジェクトの作成時に与えられた"SenderPublicKey"フィールドに関連付けられた秘密鍵を使って行う：

Wolfram Language code: arkTXSigned = BlockchainTransactionSign[arkTXMS, PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {57462485011872965801710100144286500884992829103026291705481767716456346255904, 93252910380326883084296527707983096725912573509936596202 ... 7594552434738658300043042142820255643943601719303638, "Compressed" -> True, "PublicByteArray" -> ByteArray["An8KnSxl8mGALzf1tJ8fzeENub8lLY0vZXic8HOZQYIg"], "PrivateByteArray" -> ByteArray["A24xoGmWYQ4Wnh+4YsWBXZCmI1EP+5YvkVVyCjb5XdY="]]]]

登録される多重署名のアドレスは以下のようになる：

Wolfram Language code: arkTXSigned["MultiSignatureAddress"]

送信者としての多重署名アドレス  (1)

ARKトランザクションに多重署名アドレスを送信者として署名する．この場合は"SenderPublicKey"が必須となる：

Wolfram Language code: senderPublicKey = BlockchainAddressData["DGVaLpr1BArTmAtimoDh8C5LujPTTF1EFE", "PublicKey", BlockchainBase -> {"ARK", "Devnet"}]
Wolfram Language code: arkTX = BlockchainTransaction[<| "BlockchainBase" -> {"ARK", "Devnet"}, "Recipient" -> "DGJkJXa9gq38kjSCZnvqNndn7jSWrd2zrT", "Amount" -> Quantity[520000000, "DARKtoshis"], "SenderPublicKey" -> senderPublicKey|>]

このトランザクションは，多重署名アドレスの"MinimumKeys"パラメータに従って，参加者の最小数の秘密鍵で署名されなければならない：

Wolfram Language code: BlockchainAddressData["DGVaLpr1BArTmAtimoDh8C5LujPTTF1EFE", "MultiSignature", BlockchainBase -> {"ARK", "Devnet"}]["MinimumKeys"]
Wolfram Language code: BlockchainTransactionSign[arkTX, { <|"PrivateKey" -> PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {57143976469766999610290879972632270167816533995122692469610637510833791145289, 10851753758690387871590145496903056174523413855971774365 ... 8995775012947838394065678172356468788225412929600241, "Compressed" -> True, "PublicByteArray" -> ByteArray["An5WWDH2xsLdlHqVZXPNykyC/227dNX4udiF0XX//ZVJ"], "PrivateByteArray" -> ByteArray["WRn7J2df1Dqv0nY7Hm3BOCJglO/a12+WWZWPIrHquvE="]]]|>, <|"PrivateKey" -> PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {36993751054435703412341007594940267743946195102568099488380666233303262143610, 10423346436196938680821092747767378668456564818288286644 ... 5166889460292483674185938995515423680963638343340623, "Compressed" -> True, "PublicByteArray" -> ByteArray["A1HJuJl7Ks5J4Sejgc0Q3et28NYIQKwxgjoUcSEu6aR6"], "PrivateByteArray" -> ByteArray["s01n9oGqdDM+o/dgEN72f0azYlg0p2/U/jzPSb2Fkk8="]]]|>}]

各参加者がトランザクションオブジェクトに続けて署名することも可能である：

Wolfram Language code: arkTXMS0 = BlockchainTransactionSign[arkTX, { <|"PrivateKey" -> PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {57143976469766999610290879972632270167816533995122692469610637510833791145289, 10851753758690387871590145496903056174523413855971774365 ... 8995775012947838394065678172356468788225412929600241, "Compressed" -> True, "PublicByteArray" -> ByteArray["An5WWDH2xsLdlHqVZXPNykyC/227dNX4udiF0XX//ZVJ"], "PrivateByteArray" -> ByteArray["WRn7J2df1Dqv0nY7Hm3BOCJglO/a12+WWZWPIrHquvE="]]]|> }]
Wolfram Language code: arkTXMS1 = BlockchainTransactionSign[arkTXMS0, { <|"PrivateKey" -> PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {36993751054435703412341007594940267743946195102568099488380666233303262143610, 10423346436196938680821092747767378668456564818288286644 ... 5166889460292483674185938995515423680963638343340623, "Compressed" -> True, "PublicByteArray" -> ByteArray["A1HJuJl7Ks5J4Sejgc0Q3et28NYIQKwxgjoUcSEu6aR6"], "PrivateByteArray" -> ByteArray["s01n9oGqdDM+o/dgEN72f0azYlg0p2/U/jzPSb2Fkk8="]]]|> }]
