This book is good for those who would like to open the door of blockchain world in “blockchain for dummies” mode. I was one of those, and content was informative/new for me. Mougayar brings up quite nice definition for blockchain: public economic consensus. Blockchain is Trust 2.0, it is the decentralization of trust. Current paradigm is that trust is a fundamental function of state/government, we all have witnessed that traditional trust checking has become time consuming, costly and frictional process/service, why not the Blockchain be a solution. Why do we need the central authority to ensure central trust, if we can accomplish the same trustworthiness via a network where the trust is embedded in it?
So far Blockchain has manifested itself in the following ten revelations: 1. Cryptocurrency, 2. Decentralized computing infrastructure, 3. Transaction platform, 4. Decentralized database, 5. Shared distributed accounting ledger, 6. Software development platform, 7. Open source software, 8. Financial services marketplace, 9. Peer to peer networks, 10. Trust services layer.
Authors bring up the following seven principles that we need to believe in to license the decentralized trust:
1. Blockchain is not a disintermediation of trust, it is reintermediation of trust.
2. Trust unbundling. It challenges monopolistic position of some trust providers by challenging their authority.
3. It doesn't eliminate trust, it shifts, it moves around.
4. Trust is always needed, what changes with Blockchain, is how it is delivered and earned, whoever earns the trust earns the relationship.
5. Blockchain decentralizes trust and makes way singularly harmless, but collectively powerful entities that authenticate it.
6. Blockchain disrupts the existing economics of trust because the the cost of delivering that trust is distributed.
7. Central trust distanced us, distributes trust will bring us together.
