If Indian Stock Markets Move to Blockchain, Will It Reduce Manipulation or Give More Power to Quant Firms?

If, in the future, Indian stock markets (NSE/BSE) were to shift their settlement and ownership infrastructure to blockchain, what impact would it have on market participants?

And would firms like Jane Street and other quant players gain an even bigger edge by leveraging blockchain data, technology, and speed more effectively than retail traders?

Curious to know what the community thinks.
