Scalability, decentralization, and security

Blockchain technology has three challenging issues, scalability, decentralization, and security, to satisfy concurrently and those have to be addressed to open the Web 3.0 era.

1. Scalability

   It is a factor in how much data throughput or the number of data transfers can increase as users or networks grow.

2. Decentralization

   It is a factor that shows the network operates autonomously between nodes rather than a centralized server.

3. Security

   It is a factor that how well data and programs are protected, and how well unauthorized or malicious users are prevented from accessing.
