    Explanation:
    Sharding is a blockchain scalability technique that divides the entire network’s data into smaller, manageable pieces called shards. Each shard processes its own transactions and smart contracts, improving network speed, performance, and efficiency. This concept is key for scalable blockchain infrastructure like Ethereum 2.0 and future Web3 ecosystems.

    Explanation:
    Bitcoin uses the SHA-256 cryptographic hash function to secure transactions and link blocks in the blockchain. This algorithm produces a fixed 256-bit output, ensuring immutability and resistance to tampering. By using SHA-256, Bitcoin maintains trust, decentralization, and data integrity across the network
