Blockchain through the following attributes:

• Distributed: The distributed ledger is shared and updated in real-time with every incoming transaction among the nodes connected to the Blockchain. No central server controlling the data.
• Secure Transparent : There is no unauthorized access to Blockchain made possible through Permissions and Cryptography and every node know about all transactions. 
• Consensus-based Algo: All relevant network participants must agree that a transaction is valid by use of consensus algorithms. (POW/POC)
• Flexible: Smart Contracts which are executed based on certain conditions can be written into the platform. 

Blockchain Technology Benefits:

• Time-saving: No central Authority verification needed for settlements making the process faster and cheaper. 
• Cost-saving: Participants can share assets directly. 
• Tighter security: No one can temper with Blockchain Data as it shared among millions of Participant.
