Blockchain Usages
Blockchain is a decentralized method for transactional records protected via encryption.
Each record is called a block and is hashed.
The hash for a previous block is added to the hash for the next block in the chain.
If a transaction is recorded incorrectly, it cannot be deleted; the correct values must be added as a new transaction.
Cryptocurrency transactions can be reviewed in a public ledger.
Blockchain can be used for different applications, providing integrity:
- Financial transactions
- Voting machines
- Notarization
- Identity and access management
- Data storage
