CONCLUDING REMARKS

Bitcoins blockchain fueled innovation, and a number of innovative applications have already been devised by exploiting the secure and distributed provisions of the underlying blockchain.

This clearly shows the change of value enabled by the Bitcoin blockchain technology. Namely, while the original focus of the Bitcoin blockchain was to support money transfer among users, a number of applications built around the blockchain concern other possible use cases and scenarios. Prominent applications include secure time-stamping, secure commitment schemes, and smart contracts. Note that some of these extensions cannot be deployed without changing the code base of Bitcoin (i.e., via a hard fork). These are referred to as altcoins and preserve mining power by leveraging the already established Bitcoin community.
