Hi, I thought it would be cool to share this cryptocurrency project being made in Rust (I have no part in it).
It’s called Grin and it implements the MimbleWimble transaction protocol. It’s very interesting stuff!

Introduction to MimbleWimble and Grin
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
Grin is an open source software project that implements a MimbleWimble
blockchain and fills the gaps required for a full blockchain and
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 with the number of users and not the number of transactions, with very
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.
