The Evolution of Polkadot and Blockchain

Historically, the evolution of blockchain has gone through several stages:

Bitcoin — Extremely focused on a single use (payment system).

Ethereum — Brought blockchain into general computing (smart contracts), but still limited by computational resources and scalability.

Polkadot — Establishes a scalable cloud computing system that allows different blockchains to interoperate and share security and resources.
