The IOTA team aims to solve the scaling problems of current generation blockchains by implementing what they call the “tangle” or Directed Acyclic Graph (DAG). With IOTA there are no dedicated miners involved or needed in the process of verifying network transactions unlike Bitcoin or the vast majority of other blockchains. In the place of miners, with each transaction that is made on the IOTA network, the iginal creator of the transaction must verify two other transactions on the network. In a way, the miners and users are one in the same. Each transaction requires a small amount of Proof of Work to be done on their part in order to participate on the network.

It is barely 20 years since Sergey Brin and Larry Page registered the domain name google.com, and only 10 years since Steve Jobs walked onto a stage in San Francisco and introduced the iPhone. Yet in this short period, digital technologies have upended our world.

We introduced the Digital Evolution Index in HBR in 2015 to trace the emergence of a “digital planet,” how physical interactions — in communications, social and political exchange, commerce, media and entertainment — are being displaced by digitally mediated ones.
