In Ethereum, there are two main types of transactions:Message CallandContract Creation. These transaction types enable Ethereum to support both the execution of contracts and interactions between accounts.
Key Details:
Message Call Transactions: These transactions involve interactions between externally owned accounts (EOAs) or between EOAs and smart contracts. Message calls are used to transfer Ether or invoke functions within existing smart contracts.
Contract Creation Transactions: This transaction type is used specifically to deploy new smart contracts on the Ethereum blockchain. During a contract creation transaction, the code for the new contract is included, which the network processes and stores at a unique address.
Exclusion of User Transactions: While “User” refers to EOAs, it is not a type of transaction itself in Ethereum. Transactions in Ethereum are categorized based on their purpose – either calling an existing contract (Message Call) or creating a new one (Contract Creation).
Thus,C. Message CallandD. Contract Creationare the correct answers, as they represent the two main transaction types in Ethereum.
