$BlockchainBase = "Ethereum"

BlockchainTransaction[assoc]

表示一个根据关联 assoc 中的元素构建的以太坊区块链交易.

更多信息

  • 给出以太坊区块链交易的符号表示；它不提交交易，并且交易是未签名的.
  • BlockchainTransaction[…][prop] 给出交易的属性 prop 的值.
  • 必须给出以下元素：
  • "TransactionCount"与账户相关的交易的次数
    "GasPrice"每个 gas 的价钱，单位为 wei
  • 另外还可以给出"GasLimit" 元素. 默认情况下，在内部对其进行计算：
  • "GasLimit"执行的 gas 的最大量
  • 当进行转账时，必须给出以下元素：
  • "Address"转帐的地址
    "Amount"转移的 wei 的数量
  • 部署合约时，必须给出以下元素：
  • "Contract"要在交易中部署的合约
  • 在使用纯 Solidity 代码时，合约必须是包含代码的字符串，如 "Contract""code".
  • 当使用有多个合约的纯 Solidity 代码时，必须用关联 <|"SourceCode""code","Main""name"|> 指定 "Contract"，其中 "Main" 是要部署的合约的名称.
  • 在提供含有 Solidity 代码的文件时，合约必须是一个 File，如 "Contract"->File[…].
  • 在提供含有 Solidity 代码且该代码含有多个合约的文件时，必须用关联 <|"Source"File[…],"Main""name"|> 指定 "Contract"，其中 "Main" 是要部署的合约的名称.
  • 当提供多个含有 Solidity 代码的文件时，必须用关联 <|"Source"{file1,file2,…},"Main""name"|> 指定 "Contract"，其中 {file1,file2,…} 是 File 表达式列表，其中 file1 将被编译，"Main" 是要部署的合约的名称.
  • 在使用编译过的 Solidity 代码时，必须用关联 <|"ByteCode""hexstring","ABI""spec"|> 指定 "Contract"，其中 "ABI" 为 Application Binary Interface.
  • 另外，在提供 "Contract" 的关联时，可给出额外的 "Parameters" 属性，以定义要部署的合约的初始化参数.
  • 在以太坊交易中部署自动执行的 Wolfram 语言表达式时，可以给出以下元素：
  • "WolframExpression"harvest 时要计算的表达式
    "WolframExpressionReference"对要获取和计算的表达式的指代
  • 包含 Wolfram 语言表达式的以太坊交易只能部署到以太坊 testnet.
  • 在调用合约时，必须给出以下元素：
  • "Address"合约的地址
    "FunctionCall"合约中要进行的函数调用
  • "FunctionCall" 元素可以是 Association 或 Typed 表达式.
  • 如果 "FunctionCall" 是一个 Typed 表达式，它必须定义函数名称.
  • 如果 "FunctionCall" 是一个 Association 表达式，则必须给出以下属性：
  • "Function"定义要调用的函数的 Typed 表达式
  • 也可将以下其他属性赋给 "FunctionCall" 关联：
  • "Inputs"要调用的函数的输入参数

  • BlockchainTransaction 可表示 Ethereum mainnet（默认）和 testnet (Sepolia) 交易. 如果想指定该网络，请在相应的关联中指定 "BlockchainBase" 的值或使用 BlockchainBase 选项.

范例

打开所有单元 关闭所有单元

基本范例  (2)

创建以太坊交易对象以发送 ethers：

Wolfram Language code: BlockchainTransaction[<|"TransactionCount" -> 58, "GasPrice" -> Quantity[1, "GWei"], "Address" -> "3535353535353535353535353535353535353535", "BlockchainBase" -> {"Ethereum", "Testnet"}|>]

创建以太坊交易对象并指定对 gas 的限制：

Wolfram Language code: BlockchainTransaction[<|"TransactionCount" -> 58, "GasPrice" -> Quantity[1, "GWei"], "GasLimit" -> 21000, "Address" -> "3535353535353535353535353535353535353535", "Amount" -> Quantity[0.0025, "Ethers"], "BlockchainBase" -> {"Ethereum", "Testnet"}|>]

范围  (7)

纯文本 Solidity 合约  (2)

在区块链交易中使用纯 Solidity 代码构建合约：

Wolfram Language code: solidityCode = "pragma solidity ^0.4.23; contract Test{ function sum(uint256 a, uint256 b) public pure returns (uint256) { return a+b; } } ";
Wolfram Language code: BlockchainTransaction[<|"TransactionCount" -> 58, "GasPrice" -> Quantity[1, "GWei"], "Contract" -> solidityCode, "BlockchainBase" -> {"Ethereum", "Testnet"}|>]

用含有多个合约定义的纯 Solidity 代码构建合约：

Wolfram Language code: solidityCode = "pragma solidity ^0.4.23; contract Test2{ function sum(uint256 a, uint256 b) public pure returns (uint256){ return a+b; } } contract Test is Test2{ function main(uint256 a,uint256 b) public pure returns (uint256){ return sum(a,b); } }";
Wolfram Language code: BlockchainTransaction[<|"TransactionCount" -> 58, "GasPrice" -> Quantity[1, "GWei"], "Contract" -> solidityCode, "BlockchainBase" -> {"Ethereum", "Testnet"}|>]

Solidity 合约文件   (1)

用 Solidity 文件构建合约：

Wolfram Language code: Import[File["ExampleData/sample.sol"]]
Wolfram Language code: BlockchainTransaction[<|"TransactionCount" -> 59, "GasPrice" -> Quantity[1, "GWei"], "Contract" -> <|"SourceCode" -> solidityCode, "Main" -> "Test"|>, "BlockchainBase" -> {"Ethereum", "Testnet"}|>]

用含有多个合约定义的 Solidity 文件构建合约：

Wolfram Language code: Import[File["ExampleData/sample2.sol"]]

Wolfram Language code: BlockchainTransaction[<|"BlockchainBase" -> {"Ethereum", "Testnet"}, "TransactionCount" -> 62, "Contract" -> <|"ABI" -> abi, "ByteCode" -> bytecode, "Parameters" -> {"hello", "world", 10005}|>, "GasPrice" -> Quantity[1, "Gwei"]|>]

Wolfram 语言表达式  (2)

用 Wolfram 语言表达式构建合约. 此表达式将由 Wolfram 服务器计算：

Wolfram Language code: BlockchainTransaction[<|"BlockchainBase" -> {"Ethereum", "Testnet"}, "TransactionCount" -> 63, "WolframExpression" -> Delayed[WeatherData[Entity["City", {"Lima", "Lima", "Peru"}], "Temperature"]], "GasPrice" -> Quantity[1, "Gwei"]|>]

用外部存储对象指代的 Wolfram 语言表达式构建合约. Wolfram 服务器将对指代进行计算：

Wolfram Language code: ipfsobj = ExternalStorageUpload["ExampleData/simple.m"]
Wolfram Language code: BlockchainTransaction[<|"BlockchainBase" -> {"Ethereum", "Testnet"}, "TransactionCount" -> 64, "WolframExpressionReference" -> ipfsobj, "GasPrice" -> Quantity[1, "Gwei"]|>]
Wolfram Language code: %["WolframExpressionReference"]

普通的合约调用   (1)

创建一个交易，对已部署合约中的状态变量的值进行更新：

Wolfram Language code: contractAddress = "D3201000dDa9de4f04F53B50DcfEc9Af3FBA25a7";
Wolfram Language code: BlockchainTransaction[<|"BlockchainBase" -> {"Ethereum", "Testnet"}, "TransactionCount" -> 64, "WolframExpressionReference" -> ipfsobj, "GasPrice" -> Quantity[1, "Gwei"]|>]

选项  (2)

BlockchainBase  (2)

Mainnet  (1)

创建一个 mainnet 交易：

Wolfram Language code: BlockchainTransaction[<|"TransactionCount" -> 58, "GasPrice" -> Quantity[1, "GWei"], "Address" -> "3535353535353535353535353535353535353535" |>, BlockchainBase -> "Ethereum"]

Testnet  (1)

创建一个 testnet 交易：

Wolfram Language code: BlockchainTransaction[<|"TransactionCount" -> 58, "GasPrice" -> Quantity[1, "GWei"], "Address" -> "3535353535353535353535353535353535353535" |>, BlockchainBase -> {"Ethereum", "Testnet"}]

应用  (1)

创建一个以太坊 BlockchainTransaction：

Wolfram Language code: ethTX = BlockchainTransaction[<|"BlockchainBase" -> {"Ethereum", "Testnet"}, "TransactionCount" -> 11, "GasPrice" -> Quantity[150, "GWei"], "Address" -> "61cccDcDb7617d01239D0Cfc7D1627e39EA2a2c3", "Amount" -> Quantity[0.50, "Ethers"]|>]

对交易对象进行签名：

Wolfram Language code: ethTXSigned = BlockchainTransactionSign[ethTX, PrivateKey[Association["Type" -> "EllipticCurve", "CurveName" -> "secp256k1", "PublicCurvePoint" -> {16676173248318435135530093705658075451448270649776782441185582813615674064589, 86146693258001150152237806044792681696883435827253397319 ... 84, "Compressed" -> False, "PublicByteArray" -> ByteArray[ "BCTeYSvTb1h4i8B8nUtJrM//zRHHu7GdlW16oP8LZ37NvnVM7PCJ8Qms/BwonG76LAj2PCP+VGbfyw1cFM21dNI="], "PrivateByteArray" -> ByteArray["q/aGR9Z8/pp7h2fSVcu50AHSi8r4pHPKW97/exaY34w="]]]]

将签过名的交易发送到以太坊区块链：

Wolfram Language code: ethTXSubmit = BlockchainTransactionSubmit[ethTXSigned]

通过 "TransactionID" 验证交易：

Wolfram Language code: txdata = BlockchainTransactionData[ethTXSubmit["TransactionID"], BlockchainBase -> {"Ethereum", "Testnet"}]
