Blockchain is used internally by IBM for resolving contract disputes between partners on the network. According to IBM's estimates, an average of 0.9% of its 2.9 million transactions result in disputes. These disputes lead to around US $100 million in capital being tied, up and unable to be put to work to make a profit. The capital financing cost for $100 million is not trivial. There are also significant costs associated with resolving the disputes. With the blockchain solution, IBM can combine data provided by participants in the network and create a comprehensive view of all transactions. The blockchain provides strong privacy and confidentiality controls via an access-entitling governance mechanism. This solution has greatly reduced the number of disputes.
