A Bitcoin user can’t reverse a Bitcoin transaction after confirmation. However, they can cancel a transaction if unconfirmed. A Bitcoin transaction is unconfirmed if the blockchain doesn’t approve it within 24 hours. Miners must confirm every transaction via the mining process.

Can a blockchain transaction be altered once its submitted?

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.

What is mining in blockchain technology?

Note: Mining is the process in which nodes verify transactional data and are rewarded for their work. It covers their running costs (electricity and maintenance etc.) and a small profit too for providing their services. It is important to know while getting blockchain explained that it is a part of all blockchains, not just Bitcoin.

Why does it cost money to store data on the blockchain?

This is why even storing kilobytes can cost you are fortune. When storing data on the blockchain, most often we do pay a base price for the transaction itself plus an amount per byte we want to store. If smart contracts are involved, we also pay for the execution time of the smart contract.

How will Blockchain Change the future of the economy?
