Ethereum makes some noteworthy improvements to Bitcoin’s basic architecture. In particular, it utilizes “smart contracts” that enforce the performance of a given transaction, compel parties not to renege on their agreements, and contain mechanisms for refunds should one party violate the agreement.

The long term positive coherence relationship observed between online metrics and price may be the result of another factor which we hypothesise could be technical progress. As a project makes technical progress, it is likely to have a community form around it over time, increasing online activity and also demand, and hence price, of the particular cryptocurrency. An interesting avenue of future work would be to consider the coherence between price and technical progress (via looking at each projects source code repository—these are available as cryptocurrency projects are generally open-source).
