Ethereum: OP_RETURN data transaction


Op_return Data Data: Understanding OP_R_return Function

In the latest updates, Ethereum has introduced the OP_R_return Data, which allows users to save and obtain information on their transactions. One of the main features of OP_R_R_R_ is the ability to return data at the time of transaction. However, how does it work? In this article, we will go into the Op_return’s business details and explore what you need to know.

What is the OP_R_ROPTURN?

The OP_R_R_Trern deal is a type of transaction that saves information on the previous transaction in memory rather than sending data as part of the current transaction. This allows you to store and obtain transaction data more efficiently.

How are the data returned during the transaction?

Ethereum: OP_RETURN data transaction

You don’t have to create a new TXOUT without value when designing an OP_R_R_R_R_return. Instead, you can point out that your transaction should return the saved data using the “Returndata” feature. This allows users to obtain the history of the transaction and other relevant information without sending additional data within the current transaction.

Example:

Consider the OP_R_R_Trern deal that keeps the user balance in the table “0x …/balances”:

`SOLIDITY

Balance of contract {

mapping (address => uint256) residues;

SetBalance Function (Address _user, uint256 _Balance) public {

balances [_user] = _Balance;

}

GetBalance Function (Address _user) Public view return (UINT256) {

return balances [_user];

}

}

`

You can create the following deal “OP_R_return” to use the Function OP_return:

`SOLIDITY

Pragma Solidity ^0.8.0;

Contract op_return {

Equilibrium storage;

Constructor () {

Storage.Setbalance (address (_msgsender ()), 100);

}

Function Dowork () Public {

Request (! Storage.Getbalance (Address (_MSGSENDER))), “The user is not set yet!”);

// Use saved balance data here

}

}

`

In this example, when Dowork is called, it will return the stored equilibrium data using the Returndata function.

Main Benefits

The OP_R_Trern deal brings a number of benefits:

* Improved Security : By saving data in memory and returning it during the transaction, you can reduce the amount of data to be sent throughout the network.

Increased Efficiency : The use of op_R_R_Trern transactions can improve the overall efficiency by reducing the number of transactions needed to achieve a particular goal.

Conclusion

OP_R_R_Trurn data is a powerful tool for storing and obtaining information on Ethereum transactions. With this feature, you can create more efficient and secure transactions that reduce the amount of data sent on the network. Remember to use caution when introducing OP_R_return transactions as they can affect the security and scalability of your contract.
