Here is some info. from a BBC article.
Why are the banks so excited?
"Banks do very similar things to each other, even though they compete," says Simon Taylor, vice-president of blockchain research and development at Barclays.
"They basically keep our money safe and a big computer keeps track of who has what. But getting these computers to talk to each other is remarkably complex and expensive - the tech is getting a little old," he says.
If banks started sharing data using a tailor-made version of blockchain it could remove the need for middlemen, a lot of manual processing, and speed up transactions, says Mr Taylor, thereby reducing costs.
