  • Clear: all of the operations carried out within the blockchain might be consulted and verified by any participant within the community.
  • Safe: The blockchain makes use of cryptographic strategies to guard data in order that solely licensed customers can entry it.
  • Incorruptible: the info saved on the blockchain can't be modified. Every block comprises data similar to a timestamp and hyperlinks to the earlier block, making it attainable to comply with the blockchain and thus have entry to all the knowledge that has been recorded.
  • Consensus-based structure: To be able to validate a transaction and add it to the blockchain, community contributors (known as “nodes”) should attain a consensus on its validity.
  • Computational energy with distributed ledgers: Community contributors (nodes) contribute their processing energy to validate transactions and add them to the blockchain.
