Ethereum: List of current opcodes?

opcodes ethereum: comprehensive list

The Ethereum network is built on the Wickedness programming language, which allows you to stretch interactive counteracting and decisive enclosures (DAPPS) on the Mount Blockchain Ethereum. The topic is not, the basic infrastructure also provides access to multiplying information about the elections used by the network.

In this state we laid wicked eras, access to Ethereum, they were made by tips and foundations.

What is an operational code?

OPKODES – this manual, which is a transaction or a contract function in blockchain Ethereum. Until then, it is a set of binar code that represents the operation, full program. Second words, OPCODES – this “syntax” Ethereum.

Libraries Opcodes Ethereum

To access the supported list of operations, you can use the following techniques:

• Ethereum API

  

  : Oficyal API Ethereum provides access to the operational code in the ETOPS module that gain access to the" itops.getopcodes ().

Teking Opcodes List

Nizhja is somehow due to the study in Ethereum:

• 0x00: initiate a contract or an intelligent contract

• 0x01: Call a function in counteracting or intelligent

• 0x02: Install the substitute in counteracting or intelligent

• 0x03: Consider a significant contract or intelligent

• 0x04: Petty is the second block on the web

• 0x05: promote massive opcody

• 0x06: calling a function that works, truth

• 0x07: Calling a function that works, food.

• 0x08: realize the argument, translated function

• 0x09: argument installation, translated function

• 0x10 ': trust in short and a silent block

• 0x11: Take the didactic block tags

• 0x12: repeat the values ​​of counteracting or intelligent -cable

• 0x13: count a huge course of the subject or intelligent consideration

Here are the sizes of code fragments, use loneliness to find a list of opcoda for all functions and validity:

Pragma Polidy ^0.8.0;

Contracting TRACTTRATTA {

Fun foo () public pure erzation (bool) {

Returned Isstin;

}

Functional panel (Uint256 A, Uint256 B) Public Pure VOP (Uint256) {

return a + b;

}

}

`

Using the Etops module in the API Ethereum for the OPCODES LIS list for all functions and validity:

`

Pragma Polidy ^0.8.0;

Contracting TRACTTRATTA {

Fun foo () public pure erzation (bool) {

Returned Isstin;

}

Functional panel (Uint256 A, Uint256 B) Public Pure VOP (Uint256) {

return a + b;

}

}

Contact Ethereumapiexample {

Function Getopcodes () Public Pure Return (Uint256 []) {

// Return the OPCODES list for all functions and specific

uint256 [] opcodes memory = new uint256 [] (2);

Opcodes [0] = 0x01; // foo ()

Opcodes [1] = 0x02; // Bar (Uint256 A, Uint256 B)

return opcodes;

}

}

`

One -handed overhang that the “ itops.Getopcodes () Driving this, this list cannot be scraped and can be changed over time, so as new opcods are added to Ethereum.

application

Opcody Ethereum is provided by the fundamental functional relationship for the Intelf and DAPP agreement on blockchain.
