I recently came across a project called Tallysticks, currently doing a funding round on bnktothefuture.
They are currently using a private ethereum chain for their proof of concept, but they are looking into other blockchains to find the most scalable blockchain for their project.
I thought it might a good opportunity for the HEAT team to contact them and introduce them to HEAT.
I dont know the exact tech specs needed, but they plan to store invoices on a private blockchain, their project is build to be as blockchain agnostic as possible, so the main focus is scalability.
It might not be a huge project, but they are working with Barclays with plans to add other banks.
Getting HEAT based tech into the hands of the banking industry, could help secure HEAT's place in the growing blockchain market.
Anyway I just saw their blockchain comments and thought HEAT might be a good fit.
Here is their site
