Philosophy

Great Goodness

大善
dai — great zen — goodness

DaiZen is a blockchain-based escrow service that uses a traditional Swiss-style guild system for conflict resolution. The name combines the Japanese kanji for "great" and "goodness" — a principle for building trust without intermediaries.

Each guild handles disputes within its domain — car sharing, bike rentals, apartments — so resolution is always handled by people who understand the context.
