Failure to deliver is mostly due to naked shorts and can be easily solved by a corresponding regulation. It is completely orthogonal to the Blockchain concept: one can implement settlement rules which require locating shares prior to shorting them, another implementation wouldn't care about locating shares as long as there is an obligation to cover naked short at the end of the trading day.
