Will decentralization (Web3) impact reputation tracking?

Web3 concepts (decentralized identity, blockchain reputation) have been proposed for email but face adoption challenges. Email's existing infrastructure is deeply entrenched; replacing it requires overwhelming advantage.

Potential applications: decentralized reputation that senders own rather than MBPs controlling, blockchain-verified consent records, and token-based sender attestation. These remain experimental.

Likely reality: incremental evolution of existing systems rather than revolutionary replacement. Web3 concepts may inform innovation but won't replace **DNS**-based authentication and centralized **MBP** filtering in foreseeable future.
