Web3.0 Reconstructs PR

The evolution of public relations through three technological eras demonstrates why blockchain-based PR infrastructure is inevitable.

Industrial Era (1760s-1990s): One-way broadcast communication through centralized media. Trust relied on institutional authority. Key limitation: no audience feedback loop.

Information Era (1990s-2020s): Social media enabled engagement metrics but introduced new problems. Algorithms became opaque, metrics were easily gamed, and platforms owned all relationships.

Value Era (2020s-present): Blockchain enables cryptographically verifiable on-chain actions. Trust mechanism shifts from "believe us" to "verify yourself using mathematics."

Era	Core Asset	Trust Mechanism	Key Limitation
Industrial	Physical Machines	Institutional authority	No feedback loop
Information	Data and Algorithms	Engagement metrics	Fake metrics, algorithm capture
Value	Verifiable on-chain actions	Cryptographic proof	Infrastructure emerging
