Excited to share what we've been working on.
Elph is highly scalable blockchain infrastructure for Ethereum. We're capable of handling over 5,000 transactions per second (vs. Ethereum's 15) at a fraction of the cost by using a MapReduce-like technique (lots of transactions that get executed on our chain that get submitted to Ethereum as a single transaction) that retains the trustless and security properties of Ethereum today. (For those in the blockchain space, this is done using concepts from Plasma.)
Happy to answer any questions!
