Processing Basic Transaction Scripts With Etherum
Script using Ethereum. We’ll also show you to retrieve the recipient’s of the eddress the raw transaction.
Introduction *
Ethereum is a decentralized platform that can allows developers tobuild smarters and decentralized aplications (DAPS). Transaction scripts are used to execs the pagein a blockchain, soouch as validating transactions or performing on date. Script, That’s the Sender’s Identity and the Retrievs
BASIC TX Script Example
Gere is an example of a basic tx script in solidity (the programming language uses for Ethereum development):
`Solidity
Pragma Solidity ^0.8.0;
Basictxscript {
Function Verifysender (Address Sander) in a Nice View Returns (Bool) {
// Check if the Sender's Signature matches from the ev.
Require (msg.sender == Keccak256 ("expected_public_key"), "invalid sender");
Return True;
}
Funcation GetRecipientAdd (Address Recipient) in the Public View Returns (Address) {
// Check If the Recipient's Valid by Valid by Checking for An Empty Or IncorRect Hash
Require (finger (recipient) .length> 0 && bytes (recipient) .hash == Keccak256 ("Expected_hash"), "Invalid Recipient");
Return Requient;
}
}
Example Use Case
The basictxscript interface. We’ll also Two Functions: Verifysender andEtrecipientAddrress, it will be called the contract wen it recets a transaction.
`Solidity
Pragma Solidity ^0.8.0;
ContraactPocessor {
Basictxscript basictxscript;
Eddress Public Recipient;
Setrecipient Function (Address _recipient) Public {
recipient = _recipient;
}
Function Verifysender (Address Sander) in a Nice View Returns (Bool) {
return basictxscript.verifysender (sender);
}
Funcation GetRecipientAdd () Public View Returns (Address) {
return basictxscript.getecipientaddadd (recipient);
}
}
Processing the Transaction
The Basictxscriptinterface, let's crate a news and challenge. Pient's eddress.
Solidity
Pragma Solidity ^0.8.0;
Example contract {
Transactionprocessor processor;
Uint256 Public Txhash;
Function CreaateTransaction () and Public {
// Set The Recipient's Eddress as a variable
uint256 _recipient = 0x1
// Create a new transaction and set its hash to a random value
processor.setrecipient (_requini);
txhash = block.timestamp * 1000000; // Set The Transaction Timestamp
}
Function Verifysender (Address Sander) in a Nice View Returns (Bool) {
Return Procesor.verifysender (Sender);
}
}
Running the example
Tour that example, we need to deploy
“ Solidity
Pragma Solidity ^0.8.0;
Example contract {
Transactionprocessor processor;
Uint256 Public Txhash;
Mapping (address => string) Public SenderAddressTopublickey;
Function CreaateTransaction () and Public {
// Set The Recipient’s Eddress as a variable
uint256 _recipient = 0x1
// Create a new transaction and set its hash to a random value
Processor.
