BlockchainTransactionSign (for Bitcoin Cash)

BlockchainTransactionSign[obj,key]

使用指定私钥对比特币现金区块链交易进行数字签名.

BlockchainTransactionSign[obj,{key1,key2,…}]

使用全部指定私钥 keyi 对交易进行数字签名.

BlockchainTransactionSign[obj,{assoc1,assoc2,…}]

对支付到脚本哈希 (P2SH) 交易进行数字签名，其中 associ 包含 P2SH 所需数据.

更多信息

  • 使用指定的私钥对比特币现金区块链交易进行数字签名。
  • 在 BlockchainTransactionSign[obj,…] 中，obj 是一个 BlockchainTransaction 对象.
  • 对于 BlockchainTransactionSign，其密钥必须是一个 PrivateKey 对象或表示私钥的十六进制字符串.
  • BlockchainTransactionSign 返回一个区块链交易对象，该对象的属性 True 的值为 "Signed"，并带有附加属性 "RawTransaction".
  • 对于一个比特币现金 BlockchainTransaction 对象，BlockchainTransactionSign 将使用每个输入所提供的属性 "SignatureHash" 的值来确定合适的数字签名方法.
  • 可按任意顺序提供多个私人密钥。
  • 如果交易的输入属于 P2SH 地址，则列表中的关联必须包含以下元素：
  • "Data"执行脚本时使用的元素列表
    "Script"有效的比特币脚本
  • "Data" 可以包含 PrivateKey 对象、十六进制字符串或依据脚本的比特币脚本操作码. PrivateKey 对象将用于签署相应的输入. "Script" 是一个由操作码和十六进制字符串组成的有效比特币脚本.
  • 如果交易输入与多重签名脚本有关，则列表中的关联必须包含以下元素：
  • "PrivateKeys"用于签名的 PrivateKey 对象列表
    "PublicKeys"脚本中使用的所有 PublicKey 对象列表
    "RequiredKeys"所需最少的私钥数量

基本范例  (1)

创建一个比特币现金付款到公钥哈希的 BlockchainTransaction：

Wolfram Language code: bchTX = BlockchainTransaction[<|"Inputs" -> {<|"TransactionID" -> "4fe6465bbf9ffbd621445e520126aba538d59175a0ba3c6089225e9efbea0a67", "Index" -> 1|>}, "Outputs" -> {<|"Amount" -> Quantity[0.0001, "BitcoinCashUnits"], "Address" -> "bchtest:qp7ykfna6xndcyhr5j9h5xx59xj57tvawvjc0de029"|>, <|"Amount" -> Quantity[0.008645, "BitcoinCashUnits"], "Address" -> "bchtest:qrm5whh48dvqwlza8kjete78ttsudpz0vs9r7l7arp"|>}|>, BlockchainBase -> {"BitcoinCash", "Testnet"}]

使用私钥签署交易对象：

Wolfram Language code: bchTXSigned = BlockchainTransactionSign[bchTX, PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {111371065921687716131772167801914439447104389817514716115511942584632775793360, 5267778301581478541603447949046636935512968567582755066 ... 5414116593206554949956685290123019580109420649791178, "Compressed" -> True, "PublicByteArray" -> ByteArray["AvY5yhtA3b1LZ7ggaGApsdJ8zZ3qoRT+C2rkoek909rQ"], "PrivateByteArray" -> ByteArray["aaEBjTDfGHmkprK/VruG4RW28D1SQB2FMuy2e1n8Pso="]]]]

多个密钥签署  (1)

使用多个密钥签署比特币现金交易：

Wolfram Language code: "8397c305ac2ed409e59510a730207c79a6eacd34f82a288ce5c29e4f0602662d"

P2SH 输入  (1)

使用属于 P2SH 地址的输入签署一笔比特币现金交易：

Wolfram Language code: bchTX = BlockchainTransaction[ <|"Inputs" -> {<|"TransactionID" -> "9e6b0dc24198735b40052a0a6127ab9434fb793291ef888b35683e3619d63ece", "Index" -> 0|>}, "Outputs" -> {<|"Amount" -> Quantity[0.00096, "BitcoinCashUnits"], "Address" -> "bchtest:prlsjfyxdcevxy4kjkfdk0zsfsw67f0ymcv8trldxv"|>} |>, BlockchainBase -> {"BitcoinCash", "Testnet"} ]

该关联必须包含运行创建 P2SH 地址时所使用的 "Script" 所需的 "Data".

Wolfram Language code: bchTXSigned = BlockchainTransactionSign[bchTX, <|"Data" -> {PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {41026172810365163450497325772640560266676837485610030502171167272793127408984, 11446335397538667251023888576238318911484417846681655063 ... 8060763095477992527580179805485188076543244867668915, "Compressed" -> True, "PublicByteArray" -> ByteArray["Alqz/a1GEjJ1kb/pZvelK1a1hp09wqc/evWksnJiflVY"], "PrivateByteArray" -> ByteArray["5FxO++GrxKZkpRnW5lKUO5sMZoaHzQu+u0rcGyfbC7M="]]], PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["Alqz/a1GEjJ1kb/pZvelK1a1hp09wqc/evWksnJiflVY"], "PublicCurvePoint" -> {41026172810365163450497325772640560266676837485610030502171167272793127408984, 11446335397538667251023888576238318911484417846681655063319601618785846055070}]]["PublicHexString"]}, "Script" -> "OP_DUP OP_HASH160 4088a7838506b091bad63790dee787816afced90 OP_EQUALVERIFY OP_CHECKSIG"|>]

在 "Data" 中的 PrivateKey 对象被用来为交易创建签名，而该签名出现在最终的交易对象中：

Wolfram Language code: StringTake[bchTXSigned["Inputs"][[1]]["ScriptString"], {1, 152}]

多重签名输入  (1)

使用与多重签名脚本相关的输入签署比特币交易：

Wolfram Language code: bchTX = BlockchainTransaction[<|"BlockchainBase" -> {"BitcoinCash", "Testnet"}, "Inputs" -> { <|"TransactionID" -> "f075217ca991aa791fa7c3d70f42b94129620907e79726d6900d953c972ca607", "Index" -> 0|> }, "Outputs" -> { <|"Amount" -> Quantity[4.*^-6, "BitcoinCashUnits"], "Address" -> "bchtest:pzswddl07p942n9nukjyq3d95dxawxe4ty8lp8znq2"|> }|>]

该交易必须根据参数 "RequiredKeys"，由参与者使用最少数量的私钥进行签名：

Wolfram Language code: BlockchainTransactionSign[bchTX, <|"PrivateKeys" -> {PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {51724874525444673739416721101123148946820313131304153131265018986533336040603, 48268731188414227634929888133357578613956172980857119866 ... 2945683748054256803097024204184959830409291338374588, "Compressed" -> True, "PublicByteArray" -> ByteArray["A3JbPdNVSP2qOQQGZ8L356XoOXtca+x0yN/eJRFyZsSb"], "PrivateByteArray" -> ByteArray["SpSctIIABYGROtVVkNEK5YJef7vYlAiFJfTuRCsEXbw="]]], PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {107979500881536671708232537632503185481996798629419440902689565824755056043672, 2637454808094502922642620609608402222690883176095857765 ... 9932546330509479197220801016216185613865467267293385, "Compressed" -> True, "PublicByteArray" -> ByteArray["Au66O1At9hyzPrP7jrH8x3+0Eu+iockh1KM1MemGIOaY"], "PrivateByteArray" -> ByteArray["Kdbwgcvp8l5y34qidpHOP/qLecxBydEn97nfCKKcoMk="]]]}, "PublicKeys" -> {PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["A3JbPdNVSP2qOQQGZ8L356XoOXtca+x0yN/eJRFyZsSb"], "PublicCurvePoint" -> {51724874525444673739416721101123148946820313131304153131265018986533336040603, 48268731188414227634929888133357578613956172980857119866702680060264360725427}]], PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["Au66O1At9hyzPrP7jrH8x3+0Eu+iockh1KM1MemGIOaY"], "PublicCurvePoint" -> {107979500881536671708232537632503185481996798629419440902689565824755056043672, 26374548080945029226426206096084022226908831760958577652142947530277320333564}]], PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["A2oN92oQNAuhAQWLabDZHbQ8kuwIEtlRPlY5sRPfB66R"], "PublicCurvePoint" -> {47969838552476767063979266372986347156581982326487605026895634402235021504145, 106239829386092594197652494795106677088067962409072619345894133053834318874239}]]}, "RequiredKeys" -> 2|>]

或者，交易对象可以由每个参与者按顺序签名：

Wolfram Language code: bchTXPartiallySigned = BlockchainTransactionSign[bchTX, <|"PrivateKeys" -> {PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {107979500881536671708232537632503185481996798629419440902689565824755056043672, 2637454808094502922642620609608402222690883176095857765 ... 9932546330509479197220801016216185613865467267293385, "Compressed" -> True, "PublicByteArray" -> ByteArray["Au66O1At9hyzPrP7jrH8x3+0Eu+iockh1KM1MemGIOaY"], "PrivateByteArray" -> ByteArray["Kdbwgcvp8l5y34qidpHOP/qLecxBydEn97nfCKKcoMk="]]]}, "PublicKeys" -> {PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["A3JbPdNVSP2qOQQGZ8L356XoOXtca+x0yN/eJRFyZsSb"], "PublicCurvePoint" -> {51724874525444673739416721101123148946820313131304153131265018986533336040603, 48268731188414227634929888133357578613956172980857119866702680060264360725427}]], PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["Au66O1At9hyzPrP7jrH8x3+0Eu+iockh1KM1MemGIOaY"], "PublicCurvePoint" -> {107979500881536671708232537632503185481996798629419440902689565824755056043672, 26374548080945029226426206096084022226908831760958577652142947530277320333564}]], PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["A2oN92oQNAuhAQWLabDZHbQ8kuwIEtlRPlY5sRPfB66R"], "PublicCurvePoint" -> {47969838552476767063979266372986347156581982326487605026895634402235021504145, 106239829386092594197652494795106677088067962409072619345894133053834318874239}]]}, "RequiredKeys" -> 2|>]

使用密钥签署交易对象：

Wolfram Language code: bchTXSigned = BlockchainTransactionSign[bchTX, PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {111371065921687716131772167801914439447104389817514716115511942584632775793360, 5267778301581478541603447949046636935512968567582755066 ... 5414116593206554949956685290123019580109420649791178, "Compressed" -> True, "PublicByteArray" -> ByteArray["AvY5yhtA3b1LZ7ggaGApsdJ8zZ3qoRT+C2rkoek909rQ"], "PrivateByteArray" -> ByteArray["aaEBjTDfGHmkprK/VruG4RW28D1SQB2FMuy2e1n8Pso="]]]]

将已签名的交易发送到比特币现金区块链：
