Come to BlockchainConf.Tech (http://BlockchainConf.Tech) in Atlanta USA in September for a unique discussion on how blockchain will make traditional databases obsolete. Also speaking will be Chris Ferris, BM CTO Open Technology, Chair of the Hyperledger Technical Steering Committee, Marley Gray Principal Architect - Azure Blockchain Engineering, Board of Directors - Enterprise Ethereum Alliance; and many, many more blockchain superstars. Full details can be found at BlockchainConf.Tech (http://BlockchainConf.Tech)

Blockchain will never, ever, ever made traditional databases obsolete. Blockchains cannot even come close to rivaling the speed and footprint of a standard database, SQL or No-SQL based. That's never been the point of a blockchain. What if I want to store a database of sensitive information? Why would I send it out all over the world? And yes, you could encrypt it but that's just additional overhead then.^[1] Blockchains are for having a decentralized, immutable, auditable database. Many people don't need that and don't want that. Say you have a traditional DB and someone changes their email address. All you have to do is change that value. But with a blockchain, you'd have to create another entry, taking up more space.

Blockchains solve a very niche solution, one that happened to greatly benefit Bitcoin but is not nearly as applicable in every situation as people like you make it out to be.


[1]: Actual sensitive data in a database should always be encrypted at rest. That's a big part of stopping would-be hackers from taking everything.
