Grin

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 uses a proof-of-work system called Cuckoo Cycle that searches very large graphs for cycles, i.e. a cyclic path (a path that loops back on itself).

Grin (GRIN) Features:

• Privacy by default. This enables complete fungibility without precluding the ability to selectively disclose information as needed.
• Scales mostly with the number of users and minimally with the number of transactions (<100 byte kernel), resulting in a large space-saving compared to other blockchains.
• Strong and proven cryptography. MimbleWimble only relies on Elliptic Curve Cryptography which has been tried and tested for decades.
• Design simplicity that makes it easy to audit and maintain over time.
• Community-driven, encouraging mining decentralization.
