Blockchain is a distributed, secure digital transaction record that is stored on multiple computers.

By rendering the transaction data immutable, the use of blockchain can significantly reduce the likelihood of financial fraud. This indicates that the data on the blockchain cannot be altered or tampered with and is cryptographically secure. Additionally, the blockchain distributed nature ensures that all participants have access to the same data, making fraudulent activity more difficult.

Blockchain is a distributed, decentralized, and immutable digital ledger that records and stores data securely. It is a chain of blocks with transaction data, a timestamp, and a cryptographic hash of the block before it. By employing a consensus mechanism like Proof-of-Work or Proof-of-Stake, this technology facilitates transactions that are secure, transparent, and immutable. Finance, healthcare, supply chain, and other sectors all make use of this technology. Businesses can track and manage their transactions in a secure and effective manner thanks to blockchain technology.
