Ask HN: What are new applications that can be built on blockchains?

Google golem dapps, very interesting use case.

Check out the top coins here: https://coinmarketcap.com

From there you can click on any coin and get a link back to each project's website. Exploring those should cover a good chunk of the use-cases that are popular right now.

That's a good start.

I think it makes a lot of sense to build a DNS system using contacts. Names can be auctioned off and given automatically to the highest bidder. It is also possible to set up a contract where you could trustlessly sell names. "Send $200 to an address and you will get the name". There is an auction like this in progress already, and you can participate now if you like http://ens.domains

You could do even more interesting things trustlessly. For example say, you own a valuable domain. You could borrow money and use the domain as collateral. If you do pay back, or stop making monthly payments the domain is automatically and trustlessly transferred to the lender. Or it can be put up for a trustless public auction with the proceeds going to lender to repay the loan and the rest to you, the ex-owner of the domain who failed to pay back his loan.

How about a simple clock in clock out system for payroll. here is a directory of dapps https://dapps.ethercasts.com/

How would ETH name service Domains be integrated with the browser or this is supposed to work only in onion Tor and Mist browsers
