BlockchainTransactionSign (for Litecoin)

BlockchainTransactionSign[obj,key]

digitally signs a Litecoin blockchain transaction using the specified private key.

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

digitally signs a transaction using all the keys keyi.

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

digitally signs a transaction where associ contains Pay-to-Script-Hash data.

Details

  • Digitally signs a Litecoin blockchain transaction using the specified private key.
  • In BlockchainTransactionSign[obj,…], obj is a BlockchainTransaction object.
  • The key for BlockchainTransactionSign must be a PrivateKey object or a hex string representing a private key.
  • BlockchainTransactionSign returns a blockchain transaction object with True as the value of its property "Signed" and with the added property "RawTransaction".
  • For a Litecoin BlockchainTransaction object, BlockchainTransactionSign will use the value of the property "SignatureHash" provided with each input to determine the appropriate digital signature method.
  • Multiple private keys can be given in any order.
  • If an input of the transaction belongs to a Pay-to-Script-Hash address, the association in the list must have the following elements:
  • "Data"list of elements used during the execution of the script
    "Script"valid Bitcoin script
  • "Data" may contain PrivateKey objects, hexadecimal strings or Bitcoin script opcodes according to the script. PrivateKey objects will be used for signing the corresponding input. "Script" is a valid Bitcoin script composed of opcodes and hexadecimal strings.
  • If an input of the transaction is related to a multi-signature script, the association in the list must have the following elements:
  • "PrivateKeys"list of PrivateKey objects used for signing
    "PublicKeys"list of all the PublicKey objects used in the script
    "RequiredKeys"minimum number of private keys required

Basic Examples  (1)

Create a Litecoin Pay-to-Public-Key-Hash BlockchainTransaction:

Wolfram Language code: ltcTX = BlockchainTransaction[<|"Inputs" -> {<|"TransactionID" -> "5f38f453a3a36b540fd11480f9e07ae02ed14206e4a21ff351898b16b1615a79", "Index" -> 1|>}, "Outputs" -> {<|"Amount" -> Quantity[0.0001, "Litecoins"], "Address" -> "munDTMqa9V9Uhi3P21FpkY8UfYzvQqpmoQ"|>, <|"Amount" -> Quantity[0.09977, "Litecoins"], "Address" -> "n2oz9uoyx2i5uj9wwPkj1sXN6dm8efe7n9"|>}|>, BlockchainBase -> {"Litecoin", "Testnet"}]

Sign the transaction object using a private key:

Wolfram Language code: ltcTXSigned = BlockchainTransactionSign[ltcTX, PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {48067351049682456848332087651486245083783305555783485878336439165336160262912, 86265118836901232199742833912280553529588413604147325207 ... 2189122391110402380266844823627587263308329834036977, "Compressed" -> True, "PublicByteArray" -> ByteArray["A2pFKBWbemeSGJyOJDDf0PAYeiCFpELJhS6mPqd8f1sA"], "PrivateByteArray" -> ByteArray["0fZvlotEk+koVRcqSixTrj5axlqRQV1AcEBeNPVUvvE="]]]]

Pay-to-Script-Hash Input  (1)

Sign a Litecoin transaction with an input that belongs to a Pay-to-Script-Hash address:

Wolfram Language code: ltcTX = BlockchainTransaction[ <|"Inputs" -> {<|"TransactionID" -> "1b9daf5a7bcafab46a2d9a1fc7061016d972d303520e5b3e3a42987d0cce9a6b", "Index" -> 0|>}, "Outputs" -> {<|"Amount" -> Quantity[0.049956, "Litecoins"], "Address" -> "QjrVNTdSrX5uKwKEguLdf8uNk1txGq8dqL"|>} |>, BlockchainBase -> {"Litecoin", "Testnet"} ]

The association must include the "Data" required to run the "Script" used when creating the Pay-to-Script-Hash address:

Wolfram Language code: ltcTXSigned = BlockchainTransactionSign[ltcTX, <|"Data" -> {PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {66761639592919821477469190919815924180094699857628922323270431008999548151984, 67073481882215646202832337781986508967035346830822431863 ... 2242835004181077759496032839736411347399045052265541, "Compressed" -> True, "PublicByteArray" -> ByteArray["ApOZv7oUkd489VkyiijZ23genB2qeosXkgaZayZyaGiw"], "PrivateByteArray" -> ByteArray["YIcIjOXOjhSRNn+98RprkTeQ4gQUP0oaQ60YHrQydEU="]]], PublicKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "Compressed" -> True, "PublicByteArray" -> ByteArray["ApOZv7oUkd489VkyiijZ23genB2qeosXkgaZayZyaGiw"], "PublicCurvePoint" -> {66761639592919821477469190919815924180094699857628922323270431008999548151984, 67073481882215646202832337781986508967035346830822431863975597637481339178216}]]["PublicHexString"]}, "Script" -> "OP_DUP OP_HASH160 4088a7838506b091bad63790dee787816afced90 OP_EQUALVERIFY OP_CHECKSIG"|>]

The PrivateKey object in "Data" was used to create a signature of the transaction that appears in the final transaction object:

Wolfram Language code: StringTake[ltcTXSigned["Inputs"][[1]]["ScriptString"], {1, 147}]

Multi-signature Input  (1)

Sign a Litecoin transaction with an input related to a multi-signature script:

Wolfram Language code: ltcTX = BlockchainTransaction[<|"BlockchainBase" -> {"Litecoin", "Testnet"}, "Inputs" -> { <|"TransactionID" -> "ded9b3f34da247e883e4242af710f5aa7439b2d39f47f7fcb6ba08d9abcf7e73", "Index" -> 0|> }, "Outputs" -> { <|"Amount" -> Quantity[0.00004, "Litecoins"], "Address" -> "QbGkcbSC5Y3e6cP87eLGS7EM9csQQujj9U"|> }|>]

The transaction must be signed with a minimum number of private keys from the participants according to the "RequiredKeys" parameter:

Wolfram Language code: BlockchainTransactionSign[ltcTX, <|"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|>]

Alternatively, the transaction object can be signed sequentially by each participant:

Wolfram Language code: ltcTXPartiallySigned = BlockchainTransactionSign[ltcTX, <|"PrivateKeys" -> {PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {51724874525444673739416721101123148946820313131304153131265018986533336040603, 48268731188414227634929888133357578613956172980857119866 ... 2945683748054256803097024204184959830409291338374588, "Compressed" -> True, "PublicByteArray" -> ByteArray["A3JbPdNVSP2qOQQGZ8L356XoOXtca+x0yN/eJRFyZsSb"], "PrivateByteArray" -> ByteArray["SpSctIIABYGROtVVkNEK5YJef7vYlAiFJfTuRCsEXbw="]]]}, "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|>]
