Here are three ways crowdfunding can be improved by the blockchain, but there may be more.
Almost everything we do on the web will work better with autonomous blockchain technologies such as Bitcoin & ethereum because they allow systems to be built with unbreakable rules.

Of all the blockchain technologies, Bitcoin is currently the most high profile. It is a massive area of growth in the startup eco-system.
It is vital for many Bitcoin websites and apps that Bitcoin amounts can be represented in legacy currencies such as USD or EUR. There are many APIs available for determining the current value of the Bitcoin.
