A blockchain ledger is a distributed, immutable record of transactions. It’s the backbone of cryptocurrencies like Bitcoin and Ethereum.

Understanding Blockchains
Blockchains are decentralized, meaning no single entity controls them. Information is stored in blocks, chained together cryptographically.
Accessing Public Ledgers
Public blockchains, like Bitcoin, are open to anyone. You can view the entire blockchain history. Block explorers are websites and tools that allow you to search and browse transactions, blocks, and addresses on a specific blockchain.
Using Block Explorers
Popular block explorers include Blockchain.com, Etherscan (for Ethereum), and others specific to different cryptocurrencies. These tools provide a user-friendly interface to view blockchain data.
Private Blockchains
Private blockchains have restricted access. Access typically requires permission from the network administrator.
Ledger Wallets
Ledger wallets store your private keys, which control access to your cryptocurrency. They don’t store the blockchain itself.
Important: Never share your seed phrase or private keys with anyone.
