I’m trying to think of use-cases for trusted stable-coins. The obvious one is just another way to sell products — this has failed for Bitcoin due to volatility risk. One scenario I can think of is a decentralized e-reader and e-book marketplace: - you have an e-reader app that is capable of decrypting books stored somewhere, as long as the content was encrypted with your public key - authors publish their books to contracts that accept payments via an ERC20 stable-coin - the contract responds by encrypting a copy of the book with your public key and placing it at a location your e-reader can retrieve it Are there inherent advantages to a decentralized book store vs. Amazon though? Not sure…
