Processing of basic scripts transactions with Ethereum
In this article, we will explore a simple example of how to process a script of the basic transaction (TX) using Ethereum. We will also show you how to retrieve the recipient’s address from a raw transaction.
Introduction
Ethereum is a decentralized platform that allows development to build smart contracts and decentralized applications (DAPPS). Script transactions are used to perform specific logic within blockchain, such as confirmation of transactions or calculating data success. In this example, we will focus on a simple TX script that checks the sender’s identity and retrieves the recipient’s address.
Basic TX script Example
Here’s an example of a basic TX script in firmness (a programming language used to develop Ethereum):
`Strength
Pragma Solidity ^0.8.0;
Contract BasictxScript {
Function Verifysender (Sender Address) Public View Returns (Bool) {
// Make sure the signature of the sender of our expected public key
Demand (msg.sender == Keccak256 (“expected_public_key”), “Invalid sender”);
Return of Truth;
Iche
Function of GetCiPentadress (Address Recipient) Public View Returns (Address) {
// Check that the recipient’s address is valid by checking empty or incorrect hash
Demand (Bajit (recipient) .length> 0 && Bajites (recipient) .hash == Keccak256 (“expected_hash”), “invalid recipient”);
Recipient return;
Iche
Iche
`
Example uses the case
In order to process this TX script, we need to define a contract that implements the BazictxScript interface. We will also create two functions: VERIFYSENDER I GetCiPentaddress, which the contract will call when receiving a transaction.
Strength
Pragma Solidity ^0.8.0;
Treaty transactionsProcessor {{
BasictxScript BasictxScript;
Public recipient address;
Function Setrecipient (address _recipient) public {
Recipient = _recipient;
Iche
Function Verifysender (Sender Address) Public View Returns (Bool) {
Return BasictxScript.verifysender (sender);
Iche
Function of GetCiPentaddress () Public View Returns (Address) {
RETURN BASICTXSCRIPT.Getretaddress (recipient);
Iche
Iche
`
Transaction processing
Now that we have a contract that implements the BazictxScript interface, let’s create a new transaction and call the functions to check the sender and download the recipient’s address.
`Strength
Pragma Solidity ^0.8.0;
An example of a contract {
Transaction processor processor;
NAint256 Public Txhash;
Creatransation function () public {
// Set the recipient’s address as a variable
NAint256 _Recipient = 0x123456789012345678901234567890ABCDE;
// Create a new transaction and place your hash on a random value
processor.Setrecipient (_recipient);
txhash = block.timestamp * 1000000; // Set the time tag transaction to high value
Iche
Function Verifysender (Sender Address) Public View Returns (Bool) {
Return processor.verifysender (sender);
Iche
Iche
`
Starting examples
To initiate this example, we need to implement the TransactionProcessor contract and create a new transaction using the “Example” contract. We will also update the function of Creatransation () to place the recipient’s address.
`Strength
Pragma Solidity ^0.8.0;
An example of a contract {
Transaction processor processor;
NAint256 Public Txhash;
Mapping (address => sting) public senderdress stapulky;
Creatransation function () public {
// Set the recipient’s address as a variable
NAint256 _Recipient = 0x123456789012345678901234567890ABCDE;
// Create a new transaction and place your hash on a random value
