They made an initial proposal that recommended users or applications to push arbitrary computer code into the blockchain using transactions. This is how the concept of smart contracts (or contracts for short) first emerged.
Thus, Ethereum came into being as a peer-to-peer network that works on a decentralized platform called blockchain. This securely executes and verifies application code, hitherto called smart contracts, and allows participants on the blockchain to transact with each other without a trusted central authority. Transactions are sent and received through user-created Ethereum accounts. The sender signs each transaction and incurs Ether (Ethereum’s native cryptocurrency) toward the cost of processing the transaction on the network. Transaction records are immutable, auditable, and securely distributed across the network, giving participants full ownership and visibility of transaction data.
