Bitcoin and its blockchain has been proposed, but there are clear reasons why it will not be suited to this environment.
- Bitcoin consensus is subject to attack by unregulated parties
- Bitcoin’s Proof of Work is wastefully expensive in terms of electricity
- Bitcoin’s blockchain was not designed to deal with vastly different classes of dematerialized securities
More reasons can be cited, but the industry is fairly united in its agreement that Bitcoin is interesting, but not ideal for this application. Trying to fit a round peg into a square hole has never worked.
At Ethereum Labs we are convinced, as are many in the industry, of the superiority of the Ethereum solution.
