Sweden is trialling a new land registry that uses a blockchain, dozens of startups spanning numerous sectors are poking around at possible uses, and importantly policy makers such as the European Parliament have voted in favour of a more hands-off approach towards blockchain tech regulation.... A blockchain is a ledger of records arranged in data batches called blocks that use cryptographic validation to link themselves together. Put simply, each block references and identifies the previous block by a hashing function, forming an unbroken chain, hence the name." - http://arstechnica.com/information-technology/2016/11/what-is-blockchain/
If the all the financial operations will be done virtually around the world -literally-, via an smart phone, tablet or any mobile device adapted for such function. Then where the "MONEY" will be safe? in a vault any longer or a Data Centre safe box?
Blockchain can be use not only for money transactions, -however this could be the most sensible use- but to confirm with no doubts any trnsaction so if this technology goes up in trustful technology - forecast states 4-5 years from now, so this will need more computing, connectivity and storage resources that are located in DCs.
or what do you think?
