My favourite blockchain project is IOTA

IOTA

Market capitalization: approx. $15 bln
IOTA is an open-source distributed ledger specialized in the Internet of Things. This system has no transaction fees, low confirmation time and is stable regardless the number of transactions since its technology is based on an innovative consensus model “Tangle.” This model does not have blocks, chains and miners. If you want to make a transaction, you have to approve two previous transactions pointed by the system. These actions prove that all nodes have the same current state.

The project was launched in July 2016 by David Sønstebø, a serial entrepreneur and Dominik Schiener.

In November 2017, IOTA partnered with PwC, Microsoft, Deutsche Telekom and others for data monetization program.

The company also received significant investments from the Bosch Group this year
