In a blockchain network multiple nodes share and update common records.

Every node in a blockchain system must have its own, unique set of data to function.

Blockchain networks rely on common records for coordination and trust among nodes.

All nodes in the blockchain network access one central server where all data is stored.

By encrypting the transaction data to prevent unauthorized access.

By generating a unique digital signature for each user.

By randomly assigning blocks to different places in the chain to increase security.

By creating a unique hash for each block that includes the hash of the previous block, linking them together.

The change goes unnoticed, maintaining the blockchain's integrity.

Only the altered block's hash changes, without affecting the rest of the chain.

The hash of the altered block changes, which in turn invalidates all subsequent block hashes, disrupting the chain's integrity.

The blockchain automatically corrects the alteration, restoring the original data.

To ensure each transaction is aesthetically pleasing.

To facilitate the validation of transactions by nodes in the network.

To increase the speed of transactions beyond the speed of traditional transactions.

To maintain the integrity and security of the blockchain.

The political affiliation of the user initiating the transaction.

Digital signatures to verify the identity of the parties involved.

Information about inputs and outputs for tracking transaction flow.

Balance verification to ensure the initiating party has enough funds.
