Though bitcoin has not become that popular as a currency, it could be a foundation for future revolutions in the payment system which is faster, cheaper and secure.
It could become easier to carry out international transactions.
It can be used in emerging countries with a dysfunctional financial system. An organisation called Stellar is already using this technology in countries like Nigeria and Africa to provide affordable financial services.
The technology used in blockchain could be used in other areas like transferring ownership of a property, debt, shares etc. It will eliminate all intermediaries involved in such transactions. The organisations who want to replicate the blockchain technology can choose to keep the identities of the parties public
