Grin empowers anyone to transact or save modern money without the fear of external control or oppression. Grin is designed for the decades to come, not just tomorrow. Grin wants to be usable by everyone, regardless of borders, culture, skills or access.
Grin has no amounts and no addresses. Transactions can be trivially aggregated. To hide where a newly created transaction comes from, it gets relayed privately (a "random walk") among peers before it is publicly announced.
