Grin was launched fairly Equality

In order to ensure a decentralized and equitable distribution of the currency. There are several reasons why the Grin team chose to launch the coin in this manner

Decentralized Platform

From the beginning, Grin project had been started without foundation, investors, or backed by any enterprises.


Grin is community-driven and focused on sustainable development, with a team of dedicated developers working to continuously improve the protocol and diverse community of users and miners.

Rewards Distribution

Grin has a fairer distribution model than other coins, as it was launched without an initial coin offering (ICO) or pre-mine, which can give some investors an unfair advantage


Mimblewimble combines several cryptographic techniques, such as Confidential Transactions and CoinJoin, to achieve a high level of privacy. Mimblewimble also eliminates the need for addresses on the blockchain, which helps to further obfuscate transaction data. Let’s simplify the processes as follows:

  1. Mimblewimble utilizes a unique transaction building process that requires each participant to create their own outputs. This removes the need for outputs to have an address, which enhances privacy.
  2. Next, Mimblewimble employs Confidential Transactions to encrypt amounts, with a slight modification that allows any two valid transactions to be merged into one, creating noninteractive CoinJoin on Confidential Transactions.
  3. The ability to glue transactions together allows us to combine all transactions in a block into a single transaction.
  4. Finally, Mimblewimble comes with another feature called transaction cut-through which enables us to forget every spent output without giving up the ability to validate the transactions. This allows the vast majority of block data to be forgotten, making it a scalable confidential chain.
