Exploring Blockchain with Blockchain Explorer
Blockchain is a decentralized, immutable, and distributed ledger technology that is used to record transactions using cryptography. In other words, it is a digital ledger of transactions that is designed to be secure, transparent, and tamper-proof.
Blockchain technology is based on a distributed ledger that is maintained by a network of nodes. Each node on the network has a copy of the ledger, and all nodes work together to validate and authenticate transactions. Once a transaction is validated, it is added to the blockchain, and the ledger is updated on all nodes. This ensures that the ledger is always up-to-date and accurate.
A blockchain explorer is a web-based tool that allows users to explore and interact with the blockchain. It works by connecting to a node on the blockchain network and querying the blockchain for information. Once the information is retrieved, it is parsed and displayed in a user-friendly format on the explorer. Users can use the explorer to view details about transactions, blocks, and addresses, and even track specific transactions on the blockchain.
In this lesson, you learned about blockchain technology and blockchain explorer. You learned how blockchain works and how blockchain explorer works. In the next lesson, we will talk about the different types of blockchain explorers and how to set up a blockchain explorer.
