sudokoin: Solve sudokus. Get sudokoin.

jraedisch

We will shortly start publishing sudokus on https://twitter.com/sudokoin. Sudokus will lead to https://sudokoin.com where solvers may then claim sudokoin.

The sudoku generating and solving is already working, so you can give it a try: https://sudokoin.com/a43a71a94b27c56c62c88d17d38d82d91e89f59f64f85f96g97h58h75h86i11i26i69

This is pretty much a project to getting to know the platform better, but maybe someone else might like it. Not even sure whether it fits into the contest, but since there are only 7 minutes left to submit ? we will have to find that out the hard way.

We only heard of stellar some weeks ago and started working on it last weekend, but hope that we will have a polished enough version ready for the final judgement.

There is an older sudokoin contract running on Ethereum and we want to provide different sudoku generators (written in Go) as open source.

Thank you very much for the great tech and the exciting challenge!

We are creating an anchor for issuing sudokoin credits.

We will also have to write some kind of tutorial on how to create a Stellar account and how to trust us, probably even about what Stellar is. Maybe in the far future we will integrate account functionality somehow and have some kind of user management.

Thanks for the question [unknown]

Just a quick update: https://sudokoin.com is now running on the live network. So give it a try! Sudokus are conservatively published every 6 hours or so, but we will figure out a better rhythm soon. and UX. And...

First we are going to sleep a little and respect our day jobs ?.

Any feedback/discussion greatly appreciated!

jraedisch

And now the twitter account is public ?

The idea is that you got to Twitter, solve a sudoku that hasn't been solved yet (look for ones without replies) and claim sudokoin for free (we pay the stroops).

You need a Stellar account that trusts sudokoin from GCNCTSFG2HCFUBD4ZYIHRNK5SDMHSAP2KGIP27UJMVXDKWYB4JDTPWD3 and a Twitter account (for possible later user management).

Rewards will possibly get less over time and sudokus will become harder. We haven't figured that out yet.

Cool app! I solved one, but didn't have the time to set up trust, etc.

jraedisch

@dzham Thanks! I used the laboratory transaction builder for trusting but am searching for a still easier way.

jraedisch Shouldn't be hard actually, just ask @dzham to extend his QR code format to support trust operations and integrate my QR generator widget

We still need to figure out how to make it work on desktop, i.e. custom protocol handlers.

umbrel

dzham true, but we couldn't come up with a protocol for everyone to implement. So I started from the other end: making an implementation and have some thoughts how to encourage others to follow the lead. Stargazer is the only wallet currently making it simple for users. My StellarKey willbe ready next month and we can solve for the desktop too.

I just published a blog post detailing why we switched from Ethereum to Stellar and appreciate any feedback. It tries not to make too many assumptions about the readers while still being technical enough.
Next up is a road map, and probably giving away some "pretrusted" Stellar accounts to friends.

Just a quick update: We were now officially confirmed as one of the build challenge winners and as a result are receiving and answering our first support requests, which feels absolutely amazing!

At the moment we are trying to get into contact with sudoku communities to get more people to the platform and more followers on Twitter.
With the recent rise in XLM valuation, we do not give away Stellar accounts as readily as we did in the beginning (since 40 XLM are a lot more than they used to be - which is great!). We thus hope, that something like https://github.com/stellar/stellar-protocol/issues/66 will be implemented at some time.

Apart from that, we fixed some performance and security issues in the backend and are now thinking about new features.

Stay tuned!

UPDATE

We are laying out (possible) next steps on reddit: https://www.reddit.com/r/sudoku/comments/7ox074/trying_to_merge_sudoku_solving_and_crypto_tokens/
