How does blockchain ensure data integrity?
Blockchain ensures data integrity through its decentralized and immutable nature, where each block is linked to the previous one.
What makes blockchain immutable?
Blockchain is immutable because once data is recorded in a block, it cannot be altered without changing all subsequent blocks, which requires consensus.
Can you explain what consensus means in this context?
Consensus in blockchain refers to the agreement among network participants on the validity of transactions, ensuring that all copies of the ledger are the same.
What are some common consensus mechanisms?
Common consensus mechanisms include Proof of Work, Proof of Stake, and Delegated Proof of Stake, each with its own advantages and trade-offs.
