Grimm is an implementation of magic Mimblewimble protocol.
No ICO, No Premine, No Founders Tax.
Privacy is necessary for an open society in the electronic age.
MimbleWimble was first introduced in a pseudonymous paper in 2016

Grimm uses Bitcoin's Unspent Transaction Output Model (UTXO). According to this model, there are three types of information that must be hidden in order to make a transaction confidential - sender information, recipient information, and transaction amount. Mimblewimble itself achieves this goal using the following two encryption methods.
1. Confidential Transactions:
This system was developed by Adam Beck and later continued by Gregory Maxwell. You can hide the values of transaction amounts using homomorphic encryption and blinding factor, where the former is an algorithm that splits the amount of transaction value into several parts, and the latter mixes transaction amounts with random numbers to additionally hide the values of the divided transaction amounts. In addition, in the MW transaction, the recipient receives a range of blinding factors sent by the sender to act as a private key, thus verifying ownership confirmation and completing the transaction.
This cryptographic technology was also proposed by Gregory Maxwell. The method mixes the transaction pool in such a way that it is impossible to determine who sent the money to whom. In the Mimblewimble scheme, a data block will consist of number of inputs, outputs, and signature data. However, the block can still be validated by subtracting the total inputs from the total outputs to achieving a result of zero. This is a much more efficient system compared to the Bitcoin blockchain, where it is necessary to analyze the whole history of the block to be verified and considered valid. This method also offers significant space savings and offers the execution of multiple transactions at the same time.
But Mimblewimble alone does not counteract all types of blockchain analysis. If implemented naively, Mimblewimble leaves room for peer-to-peer network type analysis, which is very similar to traditional blockchain analysis. That's why in addition to these MW methods, aggregated transactions as they spread across the network, are combined using Dandelion of peer-to-peer obfuscation technique in Grimm. During the Dandelion stem phase, before the TX's are broadcast to the P2P layer, they are being combined together (CoinJoin). And an addition to this, Decoy Outputs are used, which are added if necessary. Grimm is fundamentally private. And it's great! But you can ask - what about transparency? How I can prove a transaction to a third party? Grimm is optionally transparent. Payment Proof feature - a cryptographically secure way to prove that a certain transaction really occurred. You can copy payment proof code from your wallet and give it to someone to check (in another wallet) this transaction details (sender, receiver, amount).

We designed Grimm so that it doesn’t depend on any one person. We don’t control it. Not financially. Not physically.
How can decentralized work if only founders or entities controls the system? They accumulate taxes, head the richest lists in their projects, or play an unfair game with an unlimited extra coin emission.
Grimm is a classic fork of Beam, open source, without founders rewards, ico, premine and other commercial shit. Privacy and scalability - two most prominent problems challenges bedeviling the existing Blockchain ecosystem today. So we chose the Mimblewimble protocol, which has fully addressed these problems initially. We are not in favour of mix decentralized projects with a commercial semblance of decentralization. Grimm's got a different, absolutely decentralized way.
Just think, some founders of "crypto-projects" update their Instagram more often than GitHub. Who the f*ck needs to know what they eat? They hope that they are the J. D. Rockefellers of tomorrow. And the community supports them in that. And what about you?
ASIC resistance as core value
FAIR, OPENSOURCE, Community driven coin
Anonymous, instant mimblewimble p2p messages not stored in blockchain
P2POOL for ultimate mining decentralization
Mobile wallets for on the go privacy protection
Blockchain services for easy blockchain interaction
Smart contracts for discovering new universes
Atomic swaps for decentralized crosschain exchanges
Private assetchains based on Grimm blockchain
We want to create an active community that fully endorsed the Grimm's ideas. But if you looking for a coin for another pump and dump, and speculation is your profit.. Then get the f*ck out from our community. You don't deserve a Grimm.
Grimm is fork of BEAM. Grimm mainnet is public since the very first block. There is no developers tax, pre-mine or ICO
Rewards halving after 1 year and then halvings every 4 years 33 times in total. All mining rewards go directly to the miners.
Max block size
Grimm does away with the need for known "who" and "how many". Temporary addresses are not stored in the Blockchain. Transactions offer the highest level of security.
Grimm grows with the number of users, and transactional data stored on the blockchain does not increase as nodes store only unused outputs and block headers. As a result, the weight of blockchain is reduced by several times.
Grimm is an Equihash 150_5 variant with some special tweaks to discourage both FPGA bitstream and single-chip ASIC development.
No founders TAX. All mining rewards go directly to the miners. No ICO, STO, IEO, Premine.
As an open source platform, Grimm is not controlled by any company, foundation or individual.
The simplest wallet with built-in GPU and CPU mining capabilities. No need to be a geek. Easy-peasy, fresh and squeezy.
We are strong in our community and our friends. Join us if you will be useful for Grimm.
GRIMMERS VALUE TRANSPARENCY, FREE SPEECH, PRIVACY, DECENTRALIZATION, FREEDOM OVER WEALTH, OVER MONEY, AND OVER POWER. ONLY PATH FORWARD IS TO WORK TOGETHER TO BUILD BETTER SYSTEMS. LET’S ROCK.
