A blockchain is a distributed, immutable ledger that records transactions in a secure and transparent manner. It's like a chain of blocks, each containing a record of transactions. Once a block is added to the chain, it cannot be altered or deleted. This makes it highly secure and resistant to tampering. Here's how it works: 1. **Transaction Initiation:** When a transaction occurs, it's broadcast to the network of computers (nodes) that maintain the blockchain. 2. **Validation:** Nodes verify the transaction and add it to a block. 3. **Block Creation:** Once a block is filled with transactions, it's added to the blockchain. 4. **Chain Extension:** The new block is linked to the previous block, creating a chronological chain of records. This process ensures that all transactions are transparent, verifiable, and tamper-proof.

A crypto wallet is a software program or physical device that allows you to store, send, and receive cryptocurrencies. It's essentially a digital container for your crypto assets. When choosing a wallet, consider the following factors: * **Security:** Look for wallets with strong security features, such as multi-factor authentication and cold storage options. * **Compatibility:** Ensure that the wallet supports the cryptocurrencies you plan to use. * **User-friendliness:** Choose a wallet with an intuitive interface and easy-to-use features. * **Fees:** Compare the transaction fees charged by different wallets. There are various types of wallets available, including hardware wallets, software wallets, and exchange wallets. Choose one that aligns with your security needs and preferences.
