Blockchains (aka decentralized ledgers) can be described as data structures with the following inherent attributes:
- Decentralized: Determined by a majority consensus of the networks’ participants.
- Immutable: Data can only be added on the structure; cannot be altered or removed.
- Transparent: Data is publicly available for anyone to review.
- Open: The network is open for anyone to participate.
- Secure: Powered by strong cryptography.
