Decentralization

Decentralisation means no single entity controls all the information in the system (computers on the network) and network information, as well as rules for how the network operates, are maintained by nodes on the network using Consensus Mechanism.

1. No Single point of failure

2. No single position of control and authority

Disadvantages

1. Less throughput; Visa still serves 1000x per second more customers than Ethereum and Bitcoin.

2. Slow in its existing shape
