Ethereum is an open-source, decentralized blockchain platform that allows developers to develop and deploy decentralized applications (dApps) and smart contracts. Ethereum's structure can be divided into three main components: the Ethereum Virtual Machine (EVM), the Ethereum Network, and the Ethereum Blockchain.
Bitcoin Blockchain is a decentralized, public ledger that records all transactions made on the Bitcoin network. It is a distributed database that is maintained by a network of nodes, and serves as the backbone of the Bitcoin ecosystem. The blockchain enables secure, transparent, and tamper-proof transactions, as each transaction is recorded on the blockchain and can be verified by anyone on the network.
The Bitcoin Technology Stack refers to the collection of different layers and technologies that work together to enable the functioning of the Bitcoin network.
