How are transactions verified in blockchain?
For a public blockchain, the decision to add a transaction to the chain is made by consensus. This means that the majority of “nodes” (or computers in the network) must agree that the transaction is valid. The people who own the computers in the network are incentivised to verify transactions through rewards.

Once you make a transaction on a blockchain, your transaction data gets stored in a new block; this new block is then added to the blockchain system. Before this process can occur, the information contained in the block must first be verified by the network. This is made possible by the creation of a hash.
How is a block added to blockchain?
To be added to the blockchain, each block must contain the answer to a complex mathematical problem created using an irreversible cryptographic hash function.

What is proof of work in blockchain?
Proof of work (PoW) is a decentralized consensus mechanism that requires members of a network to expend effort solving an arbitrary mathematical puzzle to prevent anybody from gaming the system. Proof of work is used widely in cryptocurrency mining, for validating transactions and mining new tokens.
Is Bitcoin proof of stake?
Proof of stake and proof of work are the two most common types of consensus mechanisms cryptocurrencies use.
