Ethereum (ETH) co-founder Vitalik Buterin has been quite vocal recently about the non-financial applications of blockchain technology and has published a paper on June 12 listing some use cases.
In a paper titled “Where to use a blockchain in non-financial applications,” in the first place, the Ethereum mastermind said one of the biggest challenges in a cryptographic account system is the issue of private key changes.
He argued that a use case of blockchain can be in “user account key changes and recovery.”
