Ethereum: How OP_EQUALVERIFY works in a standard transaction?

Understanding of Ethereum of the Opeequals Protocol: OP_Equiverrify CEO

There have been several protocols in the world of blockchain worldwide to ensure safe and effective transactions between the parties. Such a protocol is
Ethereum , in particular its function
opeequaERRIFY (op_equverihy). In this article, we will deepen the operation of the op_equverihify in the standard Ethereum operation.

What is Opequaverify?

OpeequaERRIFY is a cryptographic technique designed by Vitalik Buterin, founder of Ethereum. It is used to verify that two operations are equal and result from the same origin without expecting digital signatures or other forms of authentication. Basically, Op_equverihy guarantees that each operation is resistant to counterfeiting and follows a set of prescribed rules.

Basics of a public key bag

It is necessary to understand how the public key bag works in blockchain operations before immersing itself in the OpeequaERRIFY.
Public Key Bag (PKH) is a digital digital imprint in
The key to the personal user . It is calculated using the following steps:

• The private key is converted to
  by encrypted message .

• This encrypted message is retained using a cryptographic algorithm, such as SHA-256 or KECCAK-256.

• The value of the bag is then stored in a public key.

op_equaverify: how does it work

Let us now apply this understanding that the OpeequaERRIFY. Here is an explanation step by step:

• Development of transactions : two parts (for example, sender and recipient) create a new operation on the Ethereum network.

• Each operation has two bags of values: Transactionhash and Laukamihash. They are used as input settings for the Opequaverify process.

• Calculate
  Public Key Mag Up

  Private key ** with Transactionhash.

• The function of the bag (for example SHA-256) applies to the values ​​of a public key bag and a transactionhash.

• If the value of the bag obtained corresponds to the expected value of a certain block height, the operation must be verified as
  equal to .

How op_equaERRIFY do you check the operation?

To verify that two surgeries are equal, the following conditions must be met:

• The same public key bag exists in both transactions.

• The values ​​of the two transactions in Transactionhash are in accordance with.

• There is a valid signature for each operation (using a private key).

If these conditions are met, Opeequalify verifies that the two transactions are derived from the same account and are equal in accordance with their expected rules. If one of these conditions is not met, the operation will be rejected by the Ethereum approval layer.

Example of use cases

Let’s say we want to check that the user sent another address (0x1234567890abcdef) ( 0x8765432109876543210Abcdef) ABCDEF), for the personal key of the sender.

Then we calculate the op_equverihy bags using the next input:

• Tx1hash: block which contains tx1

• "Numerihash1": specific value of a bag (for example 0x123456789012345678901234567890abcdef)

• Tx2hash`: the value of a bag containing tx2

If the resulting bags overlap, we have managed to verify that TX1 and TX2 are the same. If they don’t, transactions will be rejected.

Conclusion

In conclusion, Op_Equverify is an essential protocol of Ethereum to ensure the integrity and uniqueness of transactions. Understanding how it works, you can better understand the main mechanisms of blockchain technology. Before starting an operation on Ethereum, don’t forget to always check the operating bags using Opequalify.
