It's true. We have been hearing about these private blockchain solutions for years but nothing really has become of it. Other than for niche use cases there really isn't much incentive for mega cap companies to upend their current processes to implement a blockchain solution. The current system of 3 days settlement (or whatever it is) sucks but everyone is so used to it, so unless they were losing market share to a competitor using a quicker, cheaper option why would they switch.
