HSBC suggests it might have found a... use for blockchain?

Re: immutability provided by DLT

Well, we don't know how HSBC have implemented their tech. I would be very surprised if they used a 'proof of work' system like Bitcoin & Ethereum. Would they really want to spend that much on electricity? As it's a single organisation they don't necessarily need the 'double spend' protection that Bitcoin needs, so there will be other ways of giving the process the immutability guarantees required.
