Frequently Asked Questions



What is Luna?

Luna is a blockchain-built dating app. Our vision is to create the safest, smartest, most powerful connection engine possible through the use of state-of-the-art machine learning algorithms in combination with user/platform incentive alignment. We’re bringing the earth to the moon.

What does Luna offer that other dating apps do not?

Aligned incentives

People using contemporary popular dating apps quickly realize that these platforms’ goals are to keep them on the app and spending money instead of meeting compatible people. Luna’s incentives are aligned with yours by design: Luna only generates revenue when users meet in real life and/or make meaningful connections. Rather than draining your attention to get advertising and subscription revenue, Luna’s goal is to match you with the most compatible partners.

Balanced attention

Choice fatigue is common on popular apps, and users predominantly find that they are either overwhelmed by messages or largely ignored. Luna distributes attention by allowing users to limit the amount of attention they receive from potential matches. See “Haven’t apps like Bumble and Coffee Meets Bagel already solved the attention imbalance problem?” below.

Collective intelligence & trust

Luna will factor real-world feedback into its matching algorithms by asking you to privately review the person you have just met. We will use NFC technology to verify IRL (In Real Life) interactions and to protect the system from being gamed. This will help improve matching relevancy and will additionally create a trust network of reputable users who have been vetted by the Luna community. The feedback is opt-in and will not be visible on your profile. When there are enough data points, we will show you aggregate details so you can further improve your game (e.g. 55% of dates liked your sense of humor).

What is wrong with advertising and subscription models?

The trouble with advertising and subscription models is that the companies that use them are optimizing for something other than the best experience for their users.

If you connect a Facebook or Instagram account to a dating app which makes money by running advertisements, you can be assured that your data will be used to match you with more compatible ads than with more compatible partners. The major issues with subscriptions are that they are expensive (typically >$100/year) and that they are based around withholding features from non-paying users, which compromises the efficacy of matching, and the consequent utility of the platform, for everyone.

With Luna, the most powerful search tools will always be available to everyone, and your data will never be sold.

Have apps like Bumble and Coffee Meets Bagel already solved the attention imbalance problem?

It is better to correct attention imbalances as they happen rather than to make blanket assumptions about how people will behave. While it is generally true that women receive more messages and men fewer, it is not individually true. Preventing men from initiating contact with women fails as a platform for shy women and the most popular men. Furthermore, it does nothing for the LGBTQ dating pool where attention imbalances certainly exist as well.

Limiting the number of matches one can contact each day is another way to resolve attention imbalances, but the trouble is that it is restrictive to human nature: people like having the freedom to browse and contact others at will. Instead of limiting the number of outgoing messages from senders, it is better to limit the number of incoming messages onto recipients (who themselves decide the limit) and then create a mechanism to prioritize the most interested senders. This is the foundation of Luna’s approach.

Is Luna free to use?

Yes. There is no "premium" version of Luna — there is one version for everyone, which requires payment only in a subset of use cases. Luna’s full functionality is otherwise freely available to all users.

In the instance of first messaging a match whose inbox is full, you can use Stars, Luna’s token, to prioritize your message in their inbox queue. See the “Messaging System” section below.

What does blockchain have to do with dating?

Blockchain allows the alignment of user and platform incentives by capturing the value of the Luna network and sharing it with token holders. It also enables P2P transactions without need of a 3rd party, thus creating a trustless free-market ecosystem.

Why does Luna have its own token? Could you use Ethereum or some other existing cryptocurrency?

Having our own token grants us more options to customize for future use cases. This will be outlined in more detail in an upcoming blog post.

Who is making Luna?

Luna was founded in 2017 by cryptoveteran Andre Ornish. Luna is incorporated in Ireland under the name Gravity Analytics Limited and company number 613299.

Andre brought together a highly skilled group of people who believe technology’s role is to catalyze authentic human connections. Learn more about us on our team page and feel free to chat us up on Telegram.

Why the name Luna?

Luna is the first word Andre spoke. With Luna's mission close to heart, he wanted it to have a meaningful name.

What is the future of Luna?

Near-term milestones will be detailed in our upcoming public roadmap. Our long-term vision is to foster meaningful human connections, both in and beyond the world of dating.

Token Sale

What is Luna's Token Sale Timeline?

The Luna Token Sale will begin February 1st 2018 at 23:00 UTC+9.

It will end when all tokens are sold or on February 8th 2018 at 23:00 UTC+9.

All tokens will be distributed by February 15th 2018 at 23:00 UTC+9.

How do I participate in the the token sale?

1. Register at

2. You will immediately receive an email confirming the data you submitted.

3. A few days before the token sale you will receive an email indicating your acceptance or rejection to the whitelist.

4. The day of the token sale we will email you the contribution address and a link where you can verify that it is correct.

5. After verifying Luna’s Qtum address, send your QTUM there. There is no minimum amount. Your contribution will be accepted on a ‘first come, first served’ basis. This means that late contributors may be refunded after hitting our quota.

How do I stay safe during the token sale?

We have seen several phishing sites since the launch of our crowdsale. These are attempts to imitate our website using addresses that look like our official website address, and which try to trick users into sending funds to attackers. We are dealing with these sites as they appear, but we want to provide some tips on how to defend yourself against phishing:

Be careful about following links

The official link to our website is Be very cautious about following links to our website from unofficial sources, such as Facebook posts, unofficial Telegram groups or Twitter.

Use official channels only

Luna website

Luna Twitter account:

Telegram (English)

Telegram (Korean)

Kakao Group (Korean)

Only the following people offiicially represent Luna on Telegram:

Andre Ornish, CEO @meetandre

Aella, Marketing @meetaella

Escott Reid, COO @meetescott

Hrothgar, CFO @meethrothgar

Jay Schreiber, General Manager @meetjay

Miles Ornish, Content Manager @meetmiles

When in doubt, trust only the people who have the admin label in the official channel. Do not send Qtum to any address that you receive via a private message from someone claiming to be from Luna.

Thanks for your patience as we take action against these deceptive sites. We will continue to post security updates as the crowdsale progresses.

How do I fill in the KYC form?

Go to and answer each question.

You will need a photo ID (passport, national ID card, or driver's license) and the public address of a Qtum wallet whose private key you control.

What is the the Know Your Customer (KYC) form?

The KYC form is a registration process that enables us to make sure that there is a real person behind each Qtum address. It also ensures full transparency regarding the project’s funds and contributors, as well as helping us get listed on reputable exchanges faster.

Can I change my KYC information?

Yes, please submit the KYC form again with the correct information. We will be accepting changes until January 31st 12:00 UTC+9. Once the token sale starts will be unable to make any changes to your entry or your Qtum address.

What should I do if the name I wrote on the KYC form does not match the name on my passport?

Please submit the KYC form again with the correct information before January 31st 12:00 UTC+9. We will only keep the last version associated with any one email (assuming everything else is filled out properly).

Can I join the public sale if I have participated in the presale?

Yes. If you have participated in the presale and want to join the public sale, you can do so provided you use the same Qtum address that you whitelisted with.

In case you would like to change your Qtum address, fill in the KYC form again before the public sale starts and wait for the approval email. You will not be able to change this address after having contributed.

Have I been whitelisted?

We process applications on a “first come, first served” basis until our token sale allocation fills up. We will email the first batch of successful applicants January 29th.

Should I participate in the token sale directly from an exchange?

No. You should never participate in a token sale directly from an exchange. We strongly recommend that you participate in our token sale from a wallet to which you control the private keys.

Note that we will not be able to credit your wallet with any tokens sent from an exchange address. By exchange, we mean Binance, Coinone, Coinnest, Poloniex, Upbit, etc. For an extensive list of exchanges, click here.

Can I change my Qtum Address?

If you have not yet contributed:

Yes. Fill out the KYC form again with correct information — the old one will be discarded.

If you have already participated in the presale:

1. Send us an email at with the subject line: “Qtum Address Update” and the relevant information. You must:

2. Send an email from the same email address you registered with.

3. Attach the photo ID you registered with.

4. Be prepared to send a test amount to verify that you control the address you are claim to own.

5. If any of the above are not fulfilled or if there are any other security considerations, we reserve the right to not change this address.

If you have already participated in the public sale:

Unfortunately, you will not be able to change your Qtum address if you have already participated in the public sale.

Is it necessary to change the receiving address to a recently created address?

No, it is not necessary to change the address, and the address should not be changed so as to prevent security vulnerabilities. The address can be tested by sending some test Qtum to the initial address.

Can the web wallet receiving address be changed to Qtum core? (After filling out the KYC form.)

If you control your private key, you control your Stars — the receiving address must only be changed if you do not control your private key. Every change is a security risk.

I received a confirmation email but only my family name is on it. Is this okay?

Yes, this is fine.

Are there individual limits for participation?

Yes, the individual limit for participation is 2,500 QTUM.

Is there a minimum amount in order to participate?

No, there is no minimum amount in order to participate.

What currencies does Luna accept?

Luna accepts Qtum contributions only. Make sure that you control the wallet you register with and that it is not on an exchange so that we can properly issue you your tokens.

Can I send a different amount than the one I have registered with?

Yes. The amount indicated on the KYC form is not binding. This number is used as a guide to estimate how many contributors we can accept before closing our whitelist.

Can I send from a different Qtum address than the one I used to register?

No. You should only contribute from the Qtum address you used to register, otherwise we will not be able to verify that it belongs to you.

Please never send money directly from an exchange — your contribution will be lost and we will not be able to refund you.

I sent from a different Qtum address than the one I used to register. What do I do?

We may not be able to help you at this point, especially if you have contributed from an exchange.

After we have attributed all transactions, we will look into refunding transactions from addresses that are not whitelisted. Refunds will be processed Mid-March 2018.

If the token sale sells out, will overcapped QTUM be refunded?

Yes, if the token sale sells out, overcapped QTUM will be refunded.

What is a blockchain?

A blockchain is an open distributed digital ledger in which transactions made in bitcoin or other cryptocurrencies are recorded chronologically and publicly in a permanent way. This is a significant update from the double-entry bookkeeping that has been in use since ~1340 CE. Read more on Wikipedia.

What is UTXO and how does it work?

A UTXO is an unspent transaction output. In an accepted transaction in a valid blockchain payment system (such as Bitcoin), only unspent outputs can be used as inputs to a transaction. When a transaction takes place, inputs are deleted and outputs are created as new UTXOs that may then be consumed in future transactions.

In the Bitcoin network, which uses this model, a UTXO is the amount that is transferred to a Bitcoin address (along with information required to unlock the output amount*) during a transaction. Received amounts (UTXOs) are used individually during a transaction and new outputs are created — one for the receiver, and, if applicable, one for the amount that is left over (change output). The amount sent to the recipient becomes a new UTXO in the recipient’s address while the change output becomes a new UTXO in the sender’s address that may be used in a future transaction.

Can the Qtum core and Qbao wallets be used if the private key is controlled?

Yes, both the Qtum core and Qbao wallets can be used if the private key is controlled — the tokens are with the private key.

Which Qtum wallet do you recommend?

We have had a good experience with the Qbao wallet (, which also has a mobile app.

Can I use the Qtum web wallet?

Yes, you can use their Qtum web wallet (

Do not use a password to encrypt your seed. This way, you will be able to import your wallet into Qbao, which does not yet have private key support but which can move our token AND has the same seed support.

We are currently discussing with their developers the listing our token.

1. If you have not yet sent crypto, we advise you to create a Qbao wallet and to redo the KYC (with all correct information) with a Qbao receiving address.

2. If you have sent crypto and did so from a address, you should not worry. You still can access your private key and have no risk of losing your tokens; however, you may not be able to access them immediately.

Can I use a Ledger Nano S?

No. As far as we know there isn't a way to send tokens from a Ledger Nano S right now.

I have lost my private keys. Can Luna support help?

No, if you cannot access your private keys or wallet, there is nothing we can do. Its like losing your physical wallet. There’s nothing we can do about it.

In the future,  write down the mnemonic phrase when you create it, and keep that phrase in a safe place.

Are Qtum addresses case sensitive?

Yes, Qtum addresses are case sensitive.

Can Luna support confirm my transaction?

You can check yourself at any moment if your transaction is confirmed. Luna will not email or message you personally to confirm your transaction. To check if your transaction is confirmed please follow the steps below.

How do I check if my transaction is confirmed?

To check if your transaction is confirmed, follow these steps:

1. Find the Transaction Hash (TX).

2. Go to

2. Search for Transaction Hash (TX)

4. Verify that the amount sent and the Luna Qtum address match.

5. Done!

Alternatively you can also:

1. Search for the Luna Qtum address.

2. On that page, visually search for the amount you sent. Or, search on the page for the wallet you sent from.

3. If you find it, click the transaction hash (TX).

4. Done!

When will I receive my tokens?

Tokens will be distributed following the conclusion of the public sale, and they will be available for withdrawal by end of February.

How many tokens will I receive for $1?

The price for the token sale period is set at 1 Star = ~$0.001.
This means you will receive ~1000 Stars for 1 USD.

How do I create a Qtum Address with Qbao?

1. Download the Qbao app

2. Open the app and click Create Wallet

3. Give it a name and set a 6 digit PIN

4. Your Qtum address is successfully created and it has 0 Qtum. Prepare your Qtum Address for the token sale by sending the amount of Qtum you would like to contribute to your the address you have just created. Once your Qtum arrives you will see the balance updated and the transfer history as having a new entry. Also, when registering on the Luna KYC form, press "Copy" to get your Qtum address, and add it to the form.

5. Check the QTUM balance of your wallet.

6. To participate in the Luna Token Sale click Transfer, fill in Luna’s Qtum address in the "Receiver Address" field (note that the one in this screenshot is just an example).

Set the Transfer Amount to the amount of Qtum you would like to contribute (e.g. 300 QTUM). Click "Transfer" to confirm.

7. Wait for a few minutes until your transaction is confirmed. While your transfer is pending you will see a red colored sad face emoji. This is normal and there is no need to worry unless it should take more than 30 minutes.

8. After the transaction is confirmed, the icon will automatically change into a green checkmark. This means that everything went well. As your transaction is already confirmed, there is no need to request a written confirmation from the Luna team.


When does Luna launch?

The Luna demo will be available at the end of January.

How will you prevent bots and catfish from taking over the platform?

Verification will be done via a service such as the Google cloud vision api. Mid-term we also plan to integrate (anonymized) feedback from dates and conversations.


What are Stars? Do I need them to use the platform?

Stars are Luna’s native token built on the Qtum blockchain. Stars are not necessary for the use of the Luna platform. They can be used to prioritize first messages to users who are receiving an influx of attention. Later use-cases will allow for other perks.

How do I purchase Stars?

Stars will be first sold to users in early February. After that they will be available on exchanges, and eventually will be available directly in the app.

Why do I have to attach Stars to my message?

Luna’s messaging system balances supply and demand. In order to prevent anyone from being overwhelmed by too many messages, users set a daily limit on the number of first messages they can receive. If more people want to start a conversation with someone than that person’s inbox allows, senders bid using Stars for a place in the inbox.

Do I have to attach Stars to every message?

Not at all. Stars are only necessary to open a conversation with someone whose inbox is full. Once you’ve begun a conversation with someone, Stars are out of the picture.

Alternatively, instead of attaching Stars, you can queue your message with zero Stars and it will go through when, if ever, the recipient’s inbox queue is no longer full.

How is the necessary number of Stars determined?

The number of Stars you need to attach is based on demand, like an auction. If more people want to first message a certain user, the bidding price will be driven up. Keep in mind, Luna never sets artificial or arbitrary prices. Costs are determined by the market competition — by how far you’re willing to go for someone’s attention, just like in real life.

What if the value of Luna’s token goes up or down?

The people who already have stars would be affected but aside from that, the bids for messages would just go up or down with the value of Stars.

Where do Stars go?

When you attach Stars to a first message, the recipient receives the Stars (minus a fee) along with your message, provided they read your message in 36 hours. Otherwise, your stars are refunded to you in full.

Who pays the gas fee?

There are no gas fees for sending messages as messaging is handled off-chain. There will be a gas fee for withdrawals.


Who owns my data?

You own your data. If you want it gone, it is gone. Keep in mind that deleting your data will reduce the quality of your matches significantly, as well as the quality of other users’ matches.

What do you do with my data?

Data is both powerful and sensitive, so it is important to get the policies right. We will never sell your data to third parties.
