Blockchain solves the four problems we identified earlier:
Ownership problem → Decentralization gives users control
Transparency problem → Public access and timestamps create accountability
Trust problem → Immutability and cryptography replace blind trust with verifiable proof
Identity problem → Cryptographic security ensures authentic verification
Unlike traditional systems where you must trust a central authority, blockchain lets you verify everything yourself. The technology shifts us from a model of "trust me" to "verify yourself"—and that changes everything.
