How are blockchain transactions validated?
For a public blockchain, the decision to add a transaction to the chain is made by consensus.

How does proof of work validate a transaction?

Does bitcoin use proof of stake?
Proof of stake and proof of work are the two most common types of consensus mechanisms cryptocurrencies use.

Is bitcoin proof of work or stake?
Proof of work is the original crypto consensus mechanism, first used by Bitcoin. … The reason it’s called “proof of work” is because the network requires a huge amount of processing power. Proof-of-work blockchains are secured and verified by virtual miners around the world racing to be the first to solve a math puzzle.
How is ownership of bitcoin determined?
Bitcoin ownership essentially boils down to two numbers, a public key and a private key. A rough analogy is a username (public key) and a password (private key). A hash of the public key called an address is the one displayed on the blockchain.
