What are some Bitcoin / blockchain projects that are actually doing something? There are hundreds of blockchain startups out there across a range of industries -- from finance to media to property management. They have identified significant problems and ways that blockchain can solve them. On paper, it all sounds awesome.

But how many blockchain companies or projects have created working solutions? It seems to me that most companies just have ideas, and are still working on their code. In the best cases their platforms are still in the alpha stages and they might have a few users or partners (who are usually willing to pay or be paid in cryptocurrency, which makes them different from the public at large), but have not yet really made a big impact.

Can anyone think of examples of blockchain companies or projects that have a real, fully functioning platform that is actually being used by a critical mass of users who are not themselves all blockchain fanatics?

I'm not asking to be critical. I am really excited by the potential of blockchain. But when people who are not blockchain geeks ask me for examples of how blockchain is actually being used in a meaningful way today, rather than how it could theoretically be used in the future to solve all sorts of problems, I don't have good answers.

I know this question is about blockchain as a whole, not just Bitcoin, but there is no blockchain Stack Exchange, so here we are.
