Hi @nionis! I tried to apply for this bounty on GitCoin but I keep getting this error saying that somebody is already working on it. I will leave the description of my dApp here meanwhile. 😁

The idea:

Chatr is a private messaging web extension that uses HOPR mixnet and can also transfer HOPR tokens to chat participants. The idea is to have a channel to talk to other network participants and send HOPR using HOPR API v2 in a minimalist interface. New notifications are visible through non-intrusive notification counters, so the user doesn't miss anything.

Deliverables:

• Chatr prototype;
• Chatr source code on GitHub (licensed under GNU General Public License v3.0);
• Gitpod Environment to launch a local cluster ready to try out the Chatr prototype;
• Documentation following HOPR dApp standard where it is applicable.

An UI mockup is already available on Figma:

I am unable to apply on gitcoin because the project type is Traditional.
NP

Here's my Project: https://github.com/vanoob404/hopr-fsdapp
My Gitcoin profile: https://gitcoin.co/vanoob404

[nionis]

@menezesphill you may start working on your dapp :)

[nionis]

hey @vanoob404, although you haven't requested to work on the dapp as the description states, your work was part of our previous contest which makes it okay. We will check the submission next week.

[ManyRios]

To submit our work. We need to paste a link of the repo right here in this issue?

[nionis]

hey @ManyRios, you need to first get an approval for the dapp you have build, if you have already built it (because u worked on the previous contest), then simply share the link here and the team will approve it and send you 800$

[ManyRios]

Yes, I worked in the previous contest. But im finishing that one

[lyledavids]

Is deadline to submit a project on the 26August?

[nionis]

@lyledavids yes, however, the sooner the better as we want to feature our current dApps very soon

[nionis]

hey @lyledavids and @ManyRios - do you have an estimation of when your submissions will be available? Would be amazing to have them in this week.

[ManyRios]

hey @lyledavids and @ManyRios - do you have an estimation of when your submissions will be available? Would be amazing to have them in this week.

hey @vividwood, can you DM me your ethereum address through discord?

[benya7]

Hello @nionis , I want to participate in this contest.

Description:
The idea of ​​my application is to create a game without graphics.
Called Gawibawibo, it is the classic game as it is known in Korea. Gawi, Bawi, Bo. Or in the West, also known as Rock, Paper, Scissors but with decentralized thinking.

The idea is that each user can create his "move" that contains a combination of 3 possible options. For example: [gawi, gawi, bawi] . Along with this combination, the user will have to send the bet amount for this movement in HOPR tokens or in the native token of the network.
A smart contract receives the player's "move", registers it and stores the amount of the token in the contract.

From the perspective of new players, they can create new moves in the same way as the first player. Or call to play with an Id of an existing "move", to play a "move" that already exists, the player calling play must send the prize amount, equal to the original amount of tokens from the creator of the "move".

The smart contract analyzes the hashes of both players and determines the winner, transferring the total number of tokens to him.

Note: I already have a minimal prototype working in polygon, the idea is to transform it using HOPR and that it meets the standards of a HOPR Dapp. I'll deliver it this week.

I will learn the necessary concepts and can present POC (proof of concept) for this project.
Thank you. Waiting for your reply.
8) shreyan001 has applied to start work (Funders only: approve worker | reject worker).

I will be building a prediction market dapp on Hopr, where people can earn money by predicting real-world events powered by a decentralized information market. With the enhanced privacy by hopr, users can participate freely and make transactions.

With hopr clusters, users can privately create and add restricted markets to transact with limited participants.

We will initially create a full-stack dApp utilizing the hopr REST API. With an interface where market events can be curated/added by admins/users at the panel, and a design UI where users can predict the outcome on the website. Implement similar hopr play ground architecture.

People can buy Native tokens on dapp, start voting their predictions on various market events and earn their respective shares based on the outcomes of market after a fixed amount of time.

Hi @en0c-026! Thanks for your application. @nionis is on holiday at the moment, so I'll be taking over some of his bounty admin role.

Your dApp idea sounds great. Just a few questions / comments:

• How many players would it support? I'm only familiar with Western rock paper scissors, which is traditionally two-player, but looking up gawi bawi bo it seems common to play with more than two. Given our current cluster setup with default five nodes, support for three or more players would be awesome.

• I'm pretty sure the API will support messages sent with Hangul characters, which would be neat. I'll check and confirm.

• It would be great to have at least some / graphical visual elements, even if they're not complex. We plan to showcase these dApps in a new educational setting for less technical users where visuals would really help the experience.

[thewanderingeditor]

Hi @Magded,

Your dApp idea sounds very interesting. Support for private medical data is one of the main use cases we're focusing on outside of crypto. It would be great to get some more information about the kind of data you're imagining sharing, and how the wallet interaction would work.

Hey @thewanderingeditor, so my plan is to make it, so hospitals can use whichever format they would like when sharing files, so it is flexible enough to support many use cases, this may include PDF files, XLSX files, CSV, etc.
To make it easier for the user, the file would be encrypted on the client, uploaded to a web2 server, a presigned url and a decryption key would be sent through HOPR, so other hospitals can access the data ASAP securely.
I am intending on using wallets as authentication, but I would need to get more familiarized with hopper to see how far I can go with this feature.

[rast000]

Hi @thewanderingeditor can I dm you on discord?

[thewanderingeditor]

@vividwood Sure, go ahead!

[tommy-a]

Awesome great to hear, looking forward to sharing it!

[piens1]

Hey, @nionis @thewanderingeditor I had a little family emergency on the 25th (CEST), nothing that serious in the end but I had to sacrifice the time I planned to spend applying finishing touches and submitting my app. I ended up submitting it as soon as I could on the 26th before heading straight to bed, which I really hoped would still get me onto the main contest. Is that the case? You can see my submission above, it meets the contest's requirements and as far as I've tested adheres to the HOPR dApp standard.

[tnkerer]

Good news @nionis @thewanderingeditor my submission for the hopr competition has been published on the Chrome Web Store and now is much easier to try out the extension:

Hello, I am unable to withdraw the tip I received on gitcoin. I've already tried on 4 different machines with both chromium and firefox, and metamask, fortmatic wallets. Nothing happens when clicking the "Claim HOPR" button and some error appears on the devtools console. I imagine getting in touch with the gitcoin support taking a considerable amount of time, perhaps you'd be able to help me somehow? It'd be ideal if you could cancel that tip and send it to my eth wallet instead, that being:

Hi @janmaslo , I have exactly same problem! I reached gitcoin support on discord but with no success. They told me to reach support@gitcoin.co, but so far they haven't even responded (been almost a day). Im afraid there is nothing we can do

[piens1]

Hey @libengd, I received a response from gitcoin support today and they're apparently letting the bounty team know, we'll see what they do next. Did you get a response yet? I did mention you in my initial email.

Hi, gitcoin support said that address they sent tip to was provided in my account settings, but I have no idea how this address ended up there nor i have access to it. My actual address is 0x736c9Ff4a9F2a6c5899258843c8Ac37b957fc317. So if gitcoin doesnt have access to this address nor am i, looks like those money are lost forever.

[0xVaibhav11]

@libengd if that's not your address. sorry to say but all gone!!!

Am sorry to hear that guys, nothing we can do on our end, funds are always sent to your profile's designated gitcoin wallet.
