1. Privacy of telecom users: Trai to use blockchain as weapon against spams


India may be far from having its version of GDPR, but the Telecom Regulatory Authority of India (TRAI) will soon be coming to the rescue of people with a solution enabled by.... you guessed it, blockchains! With an increasing number of services selling consumer data such as phone numbers and addresses in the region, spam calls and texts have rendered the phone numbers of many useless. Putting a limit on commercial communications is difficult within existing infrastructure as spam calls often occur from SIM cards with numbers that are similar to retail consumers. The Telecom Authority in the region will soon be using a blockchain to track consent and frequency of contacting consumers. TRAI Chairman, RS Sharma stated that

“Blockchain will ensure two things — non- repudiation and confidentiality. Only those authorised will be able to access details of a subscriber and only when they need to deliver service... Trai will become the first organisation to implement this kind of a regulation"

With over 900 million telephone subscribers in the region, if done effectively, this may be the largest implementation of a consumer-facing blockchain project by a regulatory authority.
