This is a guest post from Bityogi

As of this writing version 0.10 of Bitcoin has just been released. The network in Gavin’s words is now ‘over secure’. Over 50 exchanges have propped around the world since the demise of Mt. Gox and there are now over 10,000 projects in Github that reference Bitcoin in their implementation.

However, the primary use case so far has been Bitcoin’s value in relation to FIAT. i.e, Bitcoin is being used as a currency or its replacement.

If you have been following the developments with higher level meta protocols like Mastercoin (now called OMNI), CounterParty and Colored Coins, and as these protocols start to mature, we will start seeing a lot of non-currency uses of the protocol. In fact, when Bitcoin’s chief scientist was asked on his Reddit AMA a few months ago what he was most excited about in Bitcoin development? His answer, “non-currency uses of the blockchain’s ledger-ordering ability.”


So, here is one such non-currency use case:




“Do you accept Bitcoin?” This is a standard question that many of us die-hard Bitcoiners tend to ask when shopping.

Even for the merchants that do show an interest in it, explaining what Bitcoin is, is not that easy, especially when there is a line behind you at the cash register.

“Do you accept these coupons?” — that on the other hand is a no-brainer.



Groupon’s success has shown just how viable this market is. Groupon, and other services like it, issue coupons on behalf of small merchants and besides doing the promotion and marketing, such services guarantee that

  • the purchased coupon won’t get counterfeited, and
  • the customer won’t spend the same coupon again (double-spending).

In return Groupon get’s to keep up to 50% of the revenues from the sales of such coupons.


In some surveys, up to 40% of Groupon’s customers don’t intend to use that service again. Primarily because they can’t manage the surges such promotions generate and the high costs don’t make it profitable.

These problems can now be tackled by Bitcoin’s blockchain much more efficiently.

Merchants can issue their own coupons on the Block chain and are much more in control of the quantity they issue and therefore how much they are able to redeem back. Since the issuers are directly in control of issuance, they can fine tailor the surges their promotions generate.

And what’s even better, the issuers keep 100% of the proceeds from their coupons. Groupon and services like it are completely dis-intermediated from this. The only cost to issuers would be the issuance of such coupons on the Blockchain and the transaction fees of the network. And in a future article, I hope to elaborate how these costs are negligible.

These factors alone make building coupons on the block chain an excellent value proposition. However, this is just a tip of the iceberg in the benefits realized from such an endeavor. In Part-2 of this series, I’ll introduce the idea of creating contracts between coupons, coupling coupons; that exponentially increase the value proposition of issuing coupons over the Block chain.

  1. Lest you forget the most impressive contender in the 2.0 space, Bitshares.

  2. Yes, but in this article my primary focus has been the meta protocols that are using the Bitcoin block chain. There are many other interesting technologies out there along with Bitshares, NXT, Peercoin, and lets not forget Ethereum. Ripple and Stellar are interesting projects as well. My focus for now remains on the Bitcoin block chain. The ecosystem in terms of applications is far more developed and I just see that growing more over time.

  3. I am interested in utilizing the chain. Are you involved or just commenting on such an endeavor.

  4. I am very much involved with this Jim. Not just involved but ‘committed’ to this. 🙂

    We have started the project on Github. If you’re interested, it is @ Github here .

    We have decided to use the MEAN stack and will be relying on the projects from Bitpay to integrate all the block chain related stuff.

    For the past couple of weeks Augusto (the other dev working on this) and I have been ramping up our Node.js skills on another project and will be hitting this hard very soon.

    Feel free to jump in.

  5. We are launching our first blockchain powered coupons and rebates in november.

    • Jonas,

      How is this project coming along? Are you still working on it? If you can share details of it on github, I would love to help in anyway I can.
