Understanding Blockchain Nodes
Blockchain nodes are the building blocks of the blockchain network. They are the individual computers that work together to validate transactions and maintain the security of the network. There are different types of nodes in the blockchain network, each with its own purpose and function. In this lesson, we will look at the different types of blockchain nodes.
Full nodes store a complete copy of the blockchain ledger and validate transactions. They also relay transactions and blocks to other nodes in the network. Full nodes are essential for maintaining the decentralization and security of the network. Examples of full nodes are Bitcoin Core and Geth.
Light nodes do not store a complete copy of the blockchain ledger. Instead, they only store a subset of the blockchain data. This makes them faster and more efficient than full nodes but also less secure. Examples of light nodes are Electrum and MyEtherWallet.
Masternodes are special nodes that perform additional functions beyond validating transactions. They can perform tasks such as coin mixing, decentralized governance, and instant transactions. Masternodes require a significant amount of collateral to operate and are typically used in proof-of-stake (PoS) blockchains. Examples of masternodes are Dash and PIVX.
Mining nodes are used to generate new blocks in the blockchain. They perform complex mathematical calculations to solve the proof-of-work (PoW) algorithm and validate transactions. Mining nodes require specialized hardware and consume a significant amount of energy. Examples of mining nodes are Antminer and ASIC.
