BlockchainTransaction (for bloxberg)

represents a bloxberg blockchain transaction built from the components in the association assoc.

Details

Gives a symbolic representation of a bloxberg blockchain transaction; it does not submit the transaction, and the transaction is not signed.
BlockchainTransaction[…][prop] gives the value of the property prop for the transaction.
The following elements must be given:
"TransactionCount" number of transactions associated with the account

"GasPrice" price per gas unit in berg
Additionally, the "GasLimit" element can be given. By default, it is computed internally:
"GasLimit" maximum amount of gas for execution
When doing a transfer, the following elements must be given:
"Address" address to send the transfer

"Amount" amount of berg to transfer
When deploying a contract, the following element must be given:
"Contract" contract to deploy in the transaction
When using plain Solidity code, the contract must be a string containing the code, as in "Contract""code".
When using plain Solidity code with multiple contracts, "Contract" must be specified as an association <|"SourceCode""code","Main""name"|>, where "Main" is the name of the contract to be deployed.
When providing a file containing Solidity code, the contract must be a File, as in "Contract"->File[…].
When providing a file containing Solidity code with multiple contracts, "Contract" must be specified as an association <|"Source"File[…],"Main""name"|>, where "Main" is the name of the contract to be deployed.
When providing multiple files containing Solidity code, "Contract" must be specified as an association <|"Source"{file₁,file₂,…},"Main""name"|>, where {file₁,file₂,…} is a list of File expressions from which file₁ will be compiled, and "Main" is the name of the contract to be deployed.
When using compiled Solidity code, "Contract" must be specified as an association of the form <|"ByteCode""hexstring","ABI""spec"|>, where "ABI" is the Application Binary Interface.
Additionally, when providing an association for "Contract", an extra "Parameters" property can be given to define the initialization parameters of the deploying contract.
When calling a contract, the following elements must be given:
"Address" address of the contract

"FunctionCall" function call to make in the contract
The "FunctionCall" element can be an Association or a Typed expression.
In case "FunctionCall" is a Typed expression, it must define the function name.
In case "FunctionCall" is an Association expression, the following property must be given:
"Function" Typed expression defining the function to call
The following additional properties can also be given to the "FunctionCall" association:
"Inputs" input parameters of the function to call

"Sender" address of the sender that is calling the contract
The following additional properties can also be requested from a BlockchainTransaction object:

	"Signed"	whether the transaction has been digitally signed
	"MessageHash"	hash of the unsigned transaction
	"RawTransaction"	serialized transaction
	"TransactionID"	transaction ID

BlockchainTransaction can represent bloxberg transactions. To specify this network, use the "BlockchainBase" value inside the required association or the BlockchainBase option.

Basic Examples (2)

Create a bloxberg transaction object to send bergs:

Wolfram Language code:

BlockchainTransaction[<|"TransactionCount" -> 58, 
	"GasPrice" -> Quantity[0, "bergs"], "Address" -> "2cdFffD8B15BDa30b4573B1b22Dce2d23ac86D26", 
	"BlockchainBase" -> "Bloxberg"|>]

Create a bloxberg transaction object and specify the gas limit:

Wolfram Language code:

BlockchainTransaction[<|"TransactionCount" -> 58, 
	"GasPrice" -> Quantity[0, "bergs"], "GasLimit" -> 21000, 
	"Address" -> "2cdFffD8B15BDa30b4573B1b22Dce2d23ac86D26", 
	"Amount" -> Quantity[1, "Gbrox"], 
	"BlockchainBase" -> "Bloxberg"|>]

Plain-text Solidity contract (2)

Build a contract using plain Solidity code in a blockchain transaction:

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:

Send the signed transaction to the bloxberg blockchain:

Wolfram Language code: bloxbergTXSubmitted = BlockchainTransactionSubmit[bloxbergTXSigned]

Verify the transaction using its "TransactionID":

Wolfram Language code: bloxbergTXSubmitted["TransactionID"]

Wolfram Language code: txdata = BlockchainTransactionData[bloxbergTXSubmitted["TransactionID"], BlockchainBase -> "Bloxberg"]//Dataset
