This is a demo by Jonathan Brown, founder of MIX Blockchain. MIX is based on a clone of Ethereum.
Acuity is a decentralized social media browser running on MIX and IPFS.
Acuity provides functionality similar to Reddit / Twitter, except it is peer-to-peer. It is available for Windows, Mac and Linux.
If you want to try it out you can download it from here:
Bear in mind that Acuity still has bugs and unimplemented features. Don't store any large quantity of MIX in Acuity. When it is launched for real all the smart contracts will be re-deployed, so anything published before then will be unavailable.
MIX is a blockchain/IPFS based social publication platform.
Its core values are:
-preservation of the historical record
-user controlled filter bubbles for more productive discussion
-funding content creators via incentivized tokens
Founder Jonathan Brown provides an overview of the project and details the technical architecture.
He also demos the upcoming Acuity desktop browser for MIX.
