The blockchain / trust economy trend represents a remarkable power shift from large, centralized trust agents to the individual.

With the development of blockchain, business and government will have to create new ways to engage the individual. https://dupress.deloitte.com/dup-us-en/focus/tech-trends/2017/blockchain-trust-economy.html

Blockchain technology facilitates the emergence of new forms of organizations, which have no hierarchical structure.

Users contribute to and govern the platforms. They are also shareholders of the platforms. This will enable people to cooperate toward the creation of a common good, while ensuring that everyone will be duly compensated for their efforts and contributions.

Question # 4 What are some concrete examples?

https://akasha.world/, https://steem.io/ and http://www.synereo.com/ are applications / social networks that have been deployed on a blockchain.

These applications / social networks work without a central platform and without an organization to manage the network. The platforms are run in a decentralized manner - aggregating the work of disparate groups of peers which coordinate themselves through a set of codebased rules enshrined in a blockchain. https://hbr.org/2017/03/what-blockchain-means-for-the-sharing-economy
