Ethereum Opcodes: A comprehensive list
The Ethereum network is built on a solid programming language that allows developers to create intelligent contracts and decentralized applications (DAPP) on the Ethereum block chain. However, the underlying infrastructure also offers a wealth of information on the current OPCODES program using the network.
In this article, we will give an overview of the current opcods available in Ethereum, including their definitions, types and examples.
What are your opcodes?
Opcodes are instructions that form an event or contractual call in the Ethereum block chain. They are basically a binary code that represents the activities of the program. In other words, opcodes are the “syntax” of Ethereum.
Ethereum Opcodes Library
To access the current OPCODES list, you can use the following methods:
- Ethereum API
: The official Ethereum application interface provides a list of available opcods in the
Etoppesmodule, which can be accessed using the ‘eets.getopcodes ().
- FIELD CODE CODE : Network Resources, such as Slideshare and GitHub, are provided by code snippets that show current OPCODES Network Fixedness Programs.
- Ethereum Blockchain Explorer : Ethereum Blockchain Explorer offers an online interface where you can view your existing OPCODES network for each network block.
Current Opcodes list
The following are some of the current opcoodes programs available at Ethereum:
- 0x00
: Start the status of a contract or intelligent contract
- 0x01
: Call a function of an agreement or intelligent agreement
- 0x02
: Set the variable value in contract or intelligent agreement
- 0x03
: Get a variable value from an agreement or intelligent agreement
- 0x04
: Jump into another network block
- 0x05
: Relax a set of opcodees
- 0x06
: Call a function that checks if the condition is true
- 0x07
: Call a function that checks to see if the condition is wrong
- 0x08
: Get the number of arguments transferred to the function
- 0x09
: Set the number of arguments transferred to the function
- 0x10
: Get your current block hash
- 0x11
: Get the time stamp of your current block
- 0x12
: Get the current value of the variable from a contract or intelligent agreement
- 0x13
: Get a spreadsheet value to an agreement or intelligent agreement
Here is an example of a code that uses firmness to display the OPCODES list of all functions and variables in the list of attitudes:
Solidity
Pragman solidity ^0.8.0;
Agreement ExampleContract {
function foo () Public Pure Recovery (Bool) {
return the truth;
}
Function beam (Uint256 A, Uint256 b) Pukimus Puri Palue (Uint256) {
Return A + B;
}
}
`
Using the Ethereum application interface The Etops module to get the Opcoodes list of all functions and variables:
`Solidity
Pragman solidity ^0.8.0;
Agreement ExampleContract {
function foo () Public Pure Recovery (Bool) {
return the truth;
}
Function beam (Uint256 A, Uint256 b) Pukimus Puri Palue (Uint256) {
Return A + B;
}
}
Agreement EthereumapiPEEMPLE {
Function GeTopcoodes () Public Pure Return (UINT256 []) {
// Get a list of all functions and variables opcodes
UINT256 [] Memory opcodes = new UINT256 [] (2);
Opcodes [0] = 0x01; // foo ()
Opcodes [1] = 0x02; // Bar (Uint256 A, UINT256 B)
restores opcodes;
}
}
`
Note that the `ethops.getopcodes () function appears only the OPC codes used in the fixed codes to be revised. In addition, this list may not be exhaustive and can change over time as new OPCode networks are added to the Ethereum network.
conclusion
Ethereum’s OPCODES offers fundamental functionality for smart contracts and DAP in Blockchain.
