Worum es bei uns geht

For those in Berlin who are interested in the MimbleWimble protocol and Grin cryptocurrency projects.

MimbleWimble is a blockchain format and protocol that provides extremely good scalability, privacy and fungibility by relying on strong cryptographic primitives. It addresses gaps existing in almost all current blockchain implementations.


Grin is an open source software project that implements a MimbleWimble blockchain and fills the gaps required for a full blockchain and cryptocurrency deployment.

The main goal and characteristics of the Grin project are:

* Privacy by default. This enables complete fungibility without precluding the ability to selectively disclose information as needed.
* Scales modestly with the number of transactions, keeping only a ~100 byte `kernel' for historical transactions, resulting in a large space savings 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, using an asic-resistant mining algorithm (Cuckoo Cycle) encouraging mining decentralization.
