Grin

Overview

Grin is one of the first implementations of Mimblewimble, a blockchain protocol that aims to address privacy, fungibility, and scalability. Similar to Bitcoin, Grin was introduced by a pseudonymous author and contains no pre-mine, pre-sale, or founders reward.
Grin is often compared to Beam, which is also an implementation of Mimblewimble. The major differences between Grin and Beam lay in differences between launch structure, governance, mining, and monetary policy.

Background

Grin was introduced as a partial implementation by pseudonymous developer Ignotus Peverell and is an open source community funded project. The focus of the project is to create a privacy preserving blockchain that enables scalability and fungibility. To do this, Grin uses the MimbleWimble protocol which integrates privacy focused features like confidential transactions, CoinJoin, and Dandelion. The Grin implementation uses a dual-structure Cuckoo mining algorithm that allows both ASIC and GPU mining with an ongoing monetary policy that releases one grin per second, or 60 per block reward, without adjustments or a supply cap.
