The GHOST protocol (Greedy Heaviest Observed Subtree) is a chain selection rule that is used in the Ethereum blockchain. It is a modification of the longest chain rule, which was the original chain selection rule used in Ethereum. The GHOST protocol was introduced in 2013 as a way to improve the security of the Ethereum blockchain. It does this by making it more difficult for attackers to mine e..
The Contract Application Binary Interface (ABI) in the Ethereum Virtual Machine (EVM) is a standard way to interact with smart contracts. It defines the functions and data types that are available in a smart contract and which we can use to interact with that smart contract. The ABI is a JSON file that contains information about the smart contract, such as the name of the contract, the functions..
Bytecode in EVM is the low-level programming language that is used to execute smart contracts on the Ethereum blockchain. It is generated by a compiler from Solidity code, which is a high-level programming language that is designed for writing smart contracts. EVM bytecode is a stack-based language, which means that it uses a stack to store data and instructions. The stack is a last-in-first-out..
EVM 2.0 is a major upgrade to the Ethereum Virtual Machine (EVM) that is currently in development. It is designed to improve the performance, scalability, and security of the Ethereum network. Here is a table comparing EVM 1.0 and EVM 2.0: Feature EVM 1.0 EVM 2.0 Performance Slow transaction speed, high gas fees Faster transaction speed, lower gas fees Scalability Limited scalability Increased s..
EVM : The Ethereum Virtual Machine (EVM) is a decentralized runtime environment that executes smart contracts. It is the core component of the Ethereum blockchain and is responsible for processing and validating all transactions on the network. The EVM is a stack-based virtual machine, which means that it uses a stack to store data and instructions. The stack is a last-in-first-out (LIFO) data s..
