of SIM providers to
P2P/ERP systems

Information Model
Trust your Supplier
Copyright © 2018 CHAINYARD™️

11. TrustYour Supplier – Why Blockchain
Conventional Systems are open to error, fraud and inefficiency
• In conventional systems each participant has his own, separate database, or ledger
— increasing the possibility of human error or fraud
• Shared databases cannot prevent malicious activity. Hacked entities can corrupt or
destroy data in the shared database, making it invalid for everyone involved.
• Reliance on intermediaries for validation creates inefficiencies
• Often laden with manual processes, resulting in frequent delays and inefficiencies
Blockchain is designed for trust and secure trading
• Single, shared, tamper-evident ledger — once recorded, transactions cannot be altered
• Provides levels of error checking and transaction validity not obtainable in regular
shared databases.
• Data is guaranteed to be valid and reconciled against the data held by the others
participating on the Blockchain.
• Immutably records all details of a transaction end-to-end, reducing vulnerabilities.
Blockchain Provides a Trusted, Common, Single Version of the Truth
