Ask HN: Are there any blockchain startups selling a product successfully?

17 pointsdangold1510 comments

I am trying to better understanding blockchain applications in the real world. Are there any startups using blockchain technology that have actually gained traction in their industry or proved disruptive? Note, I'm interested in finding companies that have actually proved product market fit; not ICOs, big fundraises, or have the potential to be disruptive.

- The Brave browser is being used by millions of users every months, it's powered by the BAT Token (used to pay web publishers instead of showing ads).

- The Golem token is being used to render 3d models on the Blockchain (instead of using your computer), tens of thousands of tasks have been performed by the system since it launched a few weeks ago.

None that I know of except companies solving specific problems for the crytocurrency community.

There are lots of companies doing useful things claiming to use blockchain but when you deleve into the details aren't actually using blockchain like GUTS Ticketing https://guts.tickets/

And there are lots of companies really using blockchain but of no real use like HDAC https://www.hdactech.com/

The intersection of useful and blockchain comprises of virtually no companies.

The one that springs to mind for me is https://chain.com/

They manage balances. Sounds easy, just a database column?

The problem with storing balances is securing it against unauthorised users. i.e. Hacker, DB admin.

A blockchain can be used for this, as the requests to change a balance all have to be signed. And it's very hard to re-write the blockchain history.

No, but large players could band together for intermodal waybills. They would never trust a startup to operate such a thing.

Do services for other crypto companies count? If so, there are some, along the lines of helping creating tokens, validating code security, building wallets, and of course helping with the ico process.

I think Steemit has some traction as a Reddit-like blockchain company. Wikileaks has been funded with Bitcoin donations.

They all are, ICO IS the product.

Ripple signed on some 100 banks to use their tech, not their tokens though.

Hashed Health & Change Healthcare over here in the South.

Looking at Hashed Health (particularly their What We Do on the enterprise tab of website) they appear more like a blockchain consultancy.

What is the product they are selling?
