• Blocks: The fundamental components of a blockchain are called blocks. A collection of transactions, ranging from data transfers to money transactions, are contained in each block. These pieces are connected in a chain that is arranged chronologically. A hash, a unique identification for each block, guarantees the security and integrity of the data.
• Nodes: Participants in the blockchain network are known as nodes. They might be robots, people, or even groups. The decentralized aspect of blockchain is preserved in large part via nodes. They keep a copy of the blockchain ledger, validate and verify transactions, and participate in the consensus process. Blockchain achieves transparency and immutability by distributing numerous nodes throughout the network.
• Consensus Mechanisms: These protocols and techniques allow nodes to reach a consensus over the legitimacy of transactions and determine which blocks should be appended to the chain. By using these techniques, the network's nodes can come to a consensus without the need for a central authority. Standard consensus techniques include Proof of Stake (PoS), in which validators are selected according to their current stake in the network, and Proof of Work (PoW), where miners solve challenging mathematical puzzles to validate transactions.

It is essential to grasp these fundamental elements to understand how blockchain functions. The system is secure and reliable because of its decentralized design, the use of blocks to store data, nodes' participation in transaction validation, and consensus procedures. Once you understand these ideas, you may start looking into blockchain technology's many uses and possibilities across many sectors.
