Blockchain creation Kit

Grimm is a first modular platform with a new Confidential Parallel-chains architecture that provides the ability to create your own independed mimblewimble blockchain for any project or product. New blockchains created on the Grimm platform are called Confidential Assetchains.

Features of Grimm platform:

>> Customizable. Allowing creators to change params in their own blockchain from algorithm to consensus rules. Possibility to choosing whether or not to receive upgrades from Grimm platform.
>> Confidential Assets. Possibility to allowing Assetchain users to create own assets on mimblewimble protocol like colored tokens.
>> Easy Blockchain creation Kit. Allows to create own blockchain without in-depth technical knowledge. User friendly.
>> Fast. Possibility to allowing one Assetchain to verify transactions for any other assetchain for significant increase TPS.
>> Scalable. Transactional data stored on the blockchain does not increase with the number of users, as nodes store only unused outputs and block headers. As a result, the weight of blockchain is reduced by several times.
>> Private but optionally Transparent. Assetchains operates on confidential transactions and uses a blinding factor. Only two sides are dedicated to the details of the transaction. But if necessary, the sender of the payment can generate and provide proof of payment to a third party. However, Assetchain creator can set non-confidential signatures by default.


Grimm core team

We see existing conditions and systems of control, not governed by logic or reason but by greed, corporatism, subversion, bureaucracy, censorship, and inefficiency. We have a strong distrust for inherently flawed and corrupt systems. Our value transparency, free speech, privacy, and real decentralization.
