Question

What is Bitcoin?

Answer

Bitcoin is a decentralized digital currency that operates without a central authority or banks, using blockchain technology to record all transactions across a network of computers.

Question

What is Ethereum?

Answer

Ethereum is a decentralized platform that enables the creation and operation of smart contracts and distributed applications without downtime, fraud, or interference from third parties.

Question

What is proof of stake?

Answer

Proof of stake is a consensus algorithm used in blockchain networks where validators are chosen to create new blocks based on the number of coins they hold and are willing to stake as collateral.

Question

What is proof of work?

Answer

Proof of work is a consensus algorithm used in blockchain networks that requires solving complex mathematical puzzles to confirm transactions and produce new blocks, ensuring network security.
