Yeah, I have a decent grasp of it.
There are many projects and products that are currently being developed that will provide all sorts of services. Blockchain could leave the banking industry redundant as it will provide a verification service. You do work for me, I pay you through blockchain (either directly or through a pre-agreed smart contract) and you receive payment without any need for that money to touch a bank, intermediary or middleman. The blockchain and its verification process (likely to be either a Proof of Work of Proof of Stake computer network) will do all the verification work that the banks currently do. Payment should be near instant regardless of where you are in the world (if they can get the technology to scale which is the current issue to be resolved).
If you want to learn about it you are best watching some of these:-

There are many other flavours other than bitcoin,some direct competitors and some providing specific services.
Deutsch Bank think that Blockchain is likely to reduce their workforce anywhere between 60% and 90%.
Once you learn about it you quickly realise the power of this technology and you can see all different types of industries wanting to get on board and how many jobs could be replaced.
