What does this have to do with Blockchain?
The decentralization of user data and the concept of a trustless network where no one entity is in control of the data is what much of the Blockchain is based on. Before his final release of Bitcoin Satoshi Nakamoto talked about micro payments and integrating blockchain with online transactions. He even went as far as to allow payments to be sent via simple http requests which was later scrapped from the code base. Today many blockchain businesses, tokens and coins, are based on a dapp (decentralized application) network.
In the past we were the product. Advertisers paid for our attention. In the future, via Blockchain we hope to empower users to be paid for their data. For example $MED is a decentralized blockchain for medical records. $MED benefits both patients and providers by securing patient medical records and offering unprecendeted access to providers.
Blockchain is abandoning Databases, in favor of Decentralized Ledgers
Real ideas are the only thing moving in Blockchain right now
ICOs built on hype are deflating and even worse facing SEC charges. Like in the case of CENTRA which was endorsed on social media by Floyde "Money" Mayweather.
Tokens and Coins like $TRX, $NEO, $IOTA, are moving the boundaries away from stored value and more towards practical application. We're more than just trading tokens for currency we're voting for our future, ideas fueling innovation. Military, supply chain, privacy and information security; entire sectors shifting to blockchain and the money's flowing in.
