Explain with your own words, why these are the benefits of using a blockchain.
Transparency:
The general ledger (data base) is distributed to all network participants e.g. nodes. Throughout the validation process (Consensus) the general ledgers will be updated. Changes to one node would be detected by the other network participants. Meaning, it is not possible to alter a transaction (the more time past, the more difficult it theoretically gets)
Security:
After a transaction is validated, approved and added to the blockchain, the information is stored permanently on the blockchain. In case someone wants to change a transaction, he would also need to change all âyoungerâ blocks minded afterwards. Since all hashes would change based on the one transaction being altered with. Unlikely to be hacked, since all nodes would need to be changed simultaneously
Improved traceability:
Any transaction in the process of trade - from the beginning to the end of the process - wil be stored on the blockchain. All transactions can be followed on the blockcain itself
Increased efficiency and speed:
In contrast to common e.g. banking or supply chain, with blockchain technology the intermediaries are not required in the value creation process anymore. That makes it cheaper, more efficient (less human error) and faster. No audits, books reconciliation etc. are required anymore.
Reduced cost:
In the common process intermediaries are put into the value chain as a toll-gate, in order to approve the validity / correctness to the process up to that specific moment in time. Documentation is checked and double-checked. With a blockchain based e.g. supply chain, all these additional steps are not required - thus saving costs
