Hey, check the write up on the fundition page.

But essentially, Block Deals is a site that we've created to disrupt the deals and couponing communities. These communities have a very active and engaged userbase who would respond very well to being rewarded for submitting deals via our platform which rewards them financially rather than the current sites available to them (slickdeals.net and ozbargains.com.au) which just provide rewards in reputation.

We have a huge opportunity to bring these communities over to Steemit and our platform, which could potentially increase our userbase by the thousands.
