The Nasdaq, sometimes simply referred to without the article 'the', is one of the major and most well-known stock market index, as we all know.

Distributed ledgers could, at least in theory, eliminate the need for a centralised market, which is what the Nasdaq is.

But Nasdaq is already working on that front.

A couple of years ago, it sold its market-surveillance software to seven crypto exchanges, and then it sold a blockchain eVoting product to the South African central securities depository.

Nasdaq then brought together eight companies from Sweden to develop a blockchain that could replace paper-driven trading processes, in the Swedish mutual fund market.
