Opcodes in Ethereum are the instructions that are executed by the Ethereum Virtual Machine (EVM). Opcodes can be used to perform various operations on the Ethereum blockchain, such as sending Ether or deploying smart contracts.
There are two types of opcodes: those that are part of the Ethereum protocol, and those that are part of the Ethereum Virtual Machine. The former are known as “Precompiled Opcodes” while the latter are known as “EVM Opcodes”.
Precompiled Opcodes:
The Precompiled Opcodes are a set of instructions that are part of the Ethereum Protocol. They are used to perform various operations on the Ethereum blockchain, such as sending Ether or deploying smart contracts.
NOTE: WARNING: Opcodes are a powerful tool that can be used to create and execute transactions on the Ethereum blockchain, however they should only be used by experienced developers that fully understand how they work. Incorrectly using opcodes can lead to unintended consequences, such as loss of funds, and it is recommended that only those with a deep understanding of the Ethereum blockchain use them.
There are four precompiled opcodes: ADD, MUL, SUB, and DIV. These opcodes can be used to perform arithmetic operations on integers.
EVM Opcodes:
The EVM Opcodes are a set of instructions that are part of the Ethereum Virtual Machine. They can be used to perform various operations on the Ethereum blockchain, such as sending Ether or deploying smart contracts.
There are over 200 EVM opcodes, divided into 11 categories: Arithmetic, Bitwise Logic, Cryptographic, Environmental Information, Exception Handling, Flow Control, Input/Output, Memory Access, Stack Operations, and System Operations.

Opcode is a term used in Ethereum to refer to the bytecode that is executed by the Ethereum Virtual Machine. This bytecode is used to encode data and store it on the blockchain. The opcode consists of a set of instructions that are used by the EVM to execute a contract or program.
In Ethereum, an opcode is a single instruction that is executed by the Ethereum Virtual Machine. Opcodes are the basic building blocks of smart contracts in Ethereum. Smart contracts in Ethereum are written in a high-level programming language called Solidity, which is then compiled into low-level bytecode that can be understood by the EVM.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. In the Ethereum protocol and blockchain there is a price for each operation. That price is called gas and is paid in Ether, the native currency of Ethereum.
When it comes to Ethereum, bytecode is the code that is used to run smart contracts on the Ethereum Virtual Machine (EVM). It is also the code that is stored in a contract’s code storage. In order for a contract to be executed, its bytecode must first be run through the EVM.
In Ethereum, ommers are special blocks that are mined by the network during a hard fork. When a hard fork occurs, the Ethereum network splits into two separate networks, each with its own blockchain. Ommers are blocks that are mined on the old network and then broadcast to the new network.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. Ethereum is coded in a variety of languages, the most popular being Solidity. Other languages include Serpent, LLL, and Mutan.
The cryptocurrency market is young and volatile. Ethereum has only been around since 2015, and it’s already the second most valuable cryptocurrency after Bitcoin. If you want to get in on the action, you need to start mining Ethereum.
NFC, or near-field communication, is a short-range wireless technology that allows devices to communicate with each other. NFC can be used to share data between two devices, such as two smartphones, by touching them together. NFC can also be used to make payments by waving your smartphone near a payment terminal.
Ether is the native cryptocurrency of the Ethereum network. It is used to pay for transaction fees and computational services on the Ethereum network. Ether is used as a fuel for smart contracts on the Ethereum network.
ERC stands for Ethereum Request for Comment. It is a protocol used for improving the Ethereum network. It allows developers to create new applications and improve existing ones.
