Welcome. The Etheraffle ANN and bounty campaign have now been live for 24 hours!

We've had some great feedback so far. If you have any questions regarding the project, we'll be more than happy to answer them!


Dont forget, Etheraffle is offering the equivalent of $1,000,000 in LOT tokens over in the bounty campaign, some of which can be earned by simply subscribing to or following our YouTube channel, subreddit and Instagram page!

Follow the link below for more information!

This is why we need a decentralized lottery - You can't hack user accounts if you don't need to keep any!

The pictures are beautiful. But, where is the white paper? Where is the team? In the meantime, it looks like a beautiful, but little informative advertisement. More information.

Thank you!


Oops, sorry! The info was all there it's just the buttons weren't too obvious what they were! For example these are the website and white paper links:


Not very descriptive! We've added text links to the main post now:


Thanks for the feedback - let us know if you have any more questions!

what is different Etheraffle with other lottery platform ..?

How is Etheraffle different? So many ways!

• We have no single points of failure => unlike the competition!
• We are truly decentralized => unlike the competition!
• We don't take a cut, you get it instead => unlike the competition!
• Our contracts are actually verified on etherscan.io => unlike the competition!
• We have no access to prize pools => unlike the competition!
• Our raffles run automatically & programmatically => unlike the competition!
• We give a portion of ether raised to charity => unlike the competition!

How does your technologic platform operate?    ???                           

Hello Ozinzin,

You can see how our smart contracts operate here => They're open-source on etherscan.io (https://etherscan.io/address/0x4251139bf01d46884c95b27666c9e317df68b876)

But basically it works like this:

• People play Etheraffle (https://etheraffle.com)
• Each week the winning numbers are drawn & people win ether!
• Then 15% of that week's ticket sales are put into a contract to be given to charity!
• And another 15% is put into a contract to be given to LOT token holders!

And that's it! We don't take a fee because we are also LOT token holders, just like you can be if you visit our ICO here! (https://etheraffle.com/ico)

Hello Livermore_,

Yes you can trust us, but the best bit is that we are decentralized, so you don't even have to!

And yes, there is a smart-contract function in charge of all the prize pools and raffle turn-over, meaning that no humans are involved at any step, unlike any other existing blockchain lotteries. The only people with access to the prize pool are the winners of Etheraffle! (https://etheraffle.com)

A function is also in charge of sending the ether to a contract ready for the LOT token holders (https://etheraffle.com/ico), so again, at no point do you have to trust anybody in order to get your ether when you are a LOT token holder (https://etheraffle.com/ico)!

I started to watch your site and was surprised that I did not find how to disable the voice, albeit nice, but which really hinders. and your site, it is made on a fast hand. it does not give you confidence

The graphics are like old dandy games. Maybe it's good - it causes a feeling of nostalgia, but at the same time, simplicity

Hi sergeygusev69,

You're not the only one that the auto-playing video has put off - sorry! We are going to disable it - thank you for the feedback!

Hello Greg or Larry:

I am using Brave browser.
How do I unlock my account to play Etheraffle.

Thanks

I have enabled MetaMask

Hopefully that clears things up! Let me know if you have any more issues!

Hello! Where can I find information about how much money has already been collected? And with which exchanges are you going to cooperate?

That was a very detailed instruction.  Thank you.

I sent over some ether.
https://etherscan.io/address/0xc8c6618e0fFdb0feDb49385A3dC26845A2179865

And bought a ticket for the Saturday drawing.

I don't know why, but the "Ticket Purchase In Progress ..." dialog has been up for last 6 minutes.  I think it should be much quicker than that. 

I bought another raffle ticket today.

That went through w/o any problems.

I  realized that I had to approve the transaction from the metamask.
Once I did that the purchase went through quickly and smoothly.

But the ticket for yesterday didn't go through.  It had an  error.

Approving the transaction should be included in your instruction to make sure that everyone's ticket purchase completes smoothly.

 Hi Syji!

We're sorry to hear you were having some issues!



As you later discovered, the "Ticket Purchase In Progress..." screen appears when your Ethereum Wallet/browser takes over, and it's waiting for you to confirm the transaction in your wallet/browser. So it takes as long as you take to hit submit! :)




We agree and will add an explanation to the "Ticket Purchase In Progress..." pop up to make it clearer - thank you for the feedback!




Looking at the contract we can see your transaction (https://etherscan.io/tx/0xeab3e6ec78943f36828b0c4f8dcc4fde9fb369073ef7a3ea49bccb27ec29c4e1) that errored, and the successful (https://etherscan.io/tx/0x20f434bd6638e76e73927315bc5a0c82b2a32c060ff4f60254f221925494397c) one a few minutes later - and we have figured out what happened!

It seems it was an unlucky coincidence! At around the time you made your first transaction yesterday, the ticket price was raised to reflect the now lower price of Ethereum in dollars. And during the time you were making your entry (those six minutes you mentioned above!) was when the ticket price went up. So your transaction was for only 0.002ETH and the ticket price had become 0.003ETH meaning the transaction was reverted!




Looking at the contract & you account, you can see that the price for this failed transaction was not taken from your account.


The transaction still exists and still shows up in your wallet as an outgoing one, but because it failed (and hence the red exclamation mark !), the ETH was never moved, so don't worry! You did however lose just under $0.01 in gas fees. So because of that, and because of a) Your good feedback and b) Your patience, we sent you 0.003ETH to cover your ticket price!

---

Oh, and announcement we made on twitter re an upcoming promo is nearly ready, and you'll be glad you've bought a ticket . . . ;)

Excellent. 


This is exactly why decentralized raffle system is so transparent and no one needs to guess what happened.  All details are on the blockchain. 


Thank you for your generosity!


Looking forward...

Hi.

I tried to buy LOT tokens from your web site etheraffle.com/ico.  When I clicked the [Purchase Tokens!] button, I get "Ethereum account locked! Please unlock your account to interact with this ÐApp."

Metamask was unlocked.

Well, I just sent a small amount of ether from metamask.  I didn't get the LOT token.  I thought I was supposed to receive the tokens instantly.

Would you please take a look?

Here is the transaction.
https://etherscan.io/tx/0x00e92ddd9cb5df8784a874ef2e78c2b3ab3f1cb6de3770bc702be1148f6b3d88

Can you please explain how your exchnage will be different from the competitors?

The project has a solid fundamentals and if properly implemented, this will be successful.

This is not an exchange.  This is a raffle/lottery platform that is decentralized with the all its operations transparent on the blockchain.  It also supports altruistic agenda through EthRelief.  LOT token holders get to vote on charities.

Yes, I agree that this project has a solid business fundamentals.  Unlike most new coins/tokens, this project is already implemented.  You can already participate in weekly drawings.  As the user base grows, the platform will become easier to use and make some lucky people rich while helping others in the world.

I found the solution in the FAQ section of the ICO page.
https://etheraffle.com/ico

I see the tokens.

Hello Sjyi

Oops! We forgot to refresh the ICO Dapp when you unlock your MetaMask account! We've fixed it now :)

Glad you sorted your other problem out too, I'm guessing it was that you had to "watch" for the token in MetaMask? So even though you have sorted it, we'll post this image here in case other people need help:


Also, thank you for your help in answering other questions in this thread!

Incredible news! Etheraffle has its first winner . . . ! (https://medium.com/@etheraffle_36374/incredible-news-etheraffle-has-its-first-winner-3f81ef0d1a03)

The article linked tells you who won, how it happened and why it's important!

do you have a roadmap?

After i am read this information, i become know,this project simple but very easy for undertand how to a prooft stake crytocurency. i think this good. thank you.

Hi davidcrumble2

We do! You can see it at the bottom of the ICO section here (https://etheraffle.com/ico), or a more detailed breakdown in the whitepaper (https://etheraffle.com/whitepaper). If you have any more specific questions, ask away!

---

what are the advantages investors get for supporting your project, as I see there are many similar projects and the competition in the ICO market is high?

Hi antiqklasik !

Good question - we feel that the advantages are many! There are the ETH dividends of course, plus the fact that you'd be part of something that does some good for charity! Then there's also the fact that you'd also end up owning Etheraffle (https://etheraffle.com) and so have a say on it's future!

With respect to there being similar projects - you're right of course but we feel we are far better for the following reasons:


So whilst you're right that there is a lot of competition in the ICO space, we feel we are offering something unique that can stand out from the crowd! Come and take part at the Etheraffle ICO (http://https/etheraffle.com/ico) and you won't regret it!

I read all your white paper, it looks good and you might spend a lot of time to write it

Hi sarabic23!

Thanks for looking it over - there was a lot of information to cover so it took a long time to write!

I was able to collect the 270 bonus LOT tokens from the Saturday's result page https://www.etheraffle.com/saturday

Looks like free LOT bonus is now working correctly.

Hi sjyi

Wohoo! Glad you've got it sorted! Have you checked the FAQ where you can redeem any tokens from other weeks that you might have earnt?

Ah! I just saw the FAQ for the previous week.

I'll check it out on Saturday.

Thank you,

Hi:
Another feature (a slight one) request:

Would you please make "random" a more obvious choice?  As it stands, the "random" selection is simply a different color within the text just like "Good Luck!" which is a text with the same color. 

Another button beneath the row of numbers would be good.

I see this project has a good plan. hopefully the project can be successful

I thought I was losing my posts, then I realized there are two threads for the ICO announcement.

The other thread is
https://bitcointalk.org/index.php?topic=3126664.0 (https://bitcointalk.org/index.php?topic=3126664.0)

The only difference between the title is a space between [ANN] and [ICO]. The other thread contains a space.

Can two threads be merged?

If not, somehow provide a link in the first post?

Hi ayisganteng

Thank you! We hope it's successful too!




Hi sjyi

Yes, there are two threads - you're not going crazy! :P

We made two threads due to the two different boards hopefully giving us a wider reach of viewers. I don't think they can be merged without being a moderator alas, but we are monitoring both so don't worry, we'll still see & appreciate your posts!

Project looks interesting. I will be looking out for more information, let's see another opinion giving to this project & how this project will turn out.
merculet

I've a question. How much token for 1 eth? 

Currently, 90,0000 LOT tokens per 1 Ether.

Now the ethereum price has gone up, an etheraffle ticket is down to 0.0025 eths.

Thanks sjyi for being so on it with the replies in here!!

It's my pleasure sharing information about such a good project.

the project looks interesting! you can not call the idea completely new and not similar to existing projects, but in this area it is more important to implement than uniqueness) I will follow you, good luck guys!)
egretia

Hi Calibee,

Thank you for following us! We accept that the idea is not new, but our execution certainly is! There is a lot of competition for us in this space, that's for sure, but we feel we stand out by being the only truly decentralized crypto lottery, and most importantly, the only one giving to charity!! Have you seen our table and how we compare to the competition?

There seems to be an inconsistency between the etheraffle contract https://etherscan.io/address/0x45c58bbd535b8661110ef5296e6987573d0c8276 (https://etherscan.io/address/0x45c58bbd535b8661110ef5296e6987573d0c8276) and the web page for etheraffle itself https://www.etheraffle.com/ (https://www.etheraffle.com/)

The contract shows 2.0297362825309184 Ether where as the web page shows Prizepool: 1.708003 Ether!

As of yesterday, they were in sync.

Can you provide more details for this ICO? Do you have a white paper? What's your website? I think that you need to add a website for this project to attract the attention of participants join.

You can find all the info at this URL https://etheraffle.com/ico (https://etheraffle.com/ico)

Hi Sjyi!

The article we posted yesterday here (https://medium.com/@etheraffle_36374/amazing-news-weve-had-our-first-real-winner-bc9d93b53b32) might help explain the discrepancy - though you've probably already seen it by now! There exists another reason that prize pool and the contract balance may not always be in sync as well, but we are currently writing a second article to explain that more thoroughly.

Ah....
Another winner!

Someday, I'll be one  ;D

Fingers crossed!! Have you had any two-match wins for a free go?

No... I had several one matches.

So close! Send us your ethereum address and we'll send you a FreeLOT token so you can test out the free entry mechanism for us...

Here is my address
0xc8c6618e0fFdb0feDb49385A3dC26845A2179865

Looking forward to trying out the free entry mechanism.

All the best to all the authors of the project and its participants. You created an amazing project.
egretia

I just noticed that I can redeem promotion LOT token anyday, not just Saturday.

For my account Number of tokens listed in Metamask (68250) and Etherscan https://etherscan.io/tokenholdings?a=0xc8c6618e0ffdb0fedb49385a3dc26845a2179865 (https://etherscan.io/tokenholdings?a=0xc8c6618e0ffdb0fedb49385a3dc26845a2179865) (68050) are not in sync.

The difference seems to be the promotion LOT token (200).

Hi Sjyi

That is interesting! The MetaMask token section should be pointing towards the LOT smart-contract to get it's value! I wonder how they have got out of sync? Are they still out of sync? Etherscan can occasionally lag behind a little on token transfers when reading a contract so it could be that?

Also, here's your FreeLOT token (https://etherscan.io/tx/0x7f727b8c88d69e28c1df5929ef2cec516e9b69da5783aaaf70ccf443216a9aa5)! Let us know how it goes!

Hi egretia

Thank you for your kind words!

Thanks for the freeLOT.

I had to "ADD TOKEN" using the FreeLOT contract address 0xc39f7bb97b31102c923daf02ba3d1bd16424f4bb to receive it.

Then I had 1 FreeLOT showing up on Metamask.

My steps are captured and shown here https://imgur.com/a/4T1QFFF (https://imgur.com/a/4T1QFFF)

Until I chose the numbers and clicked "BUY TICKET!" there was no difference from the normal process.

After clicking "BUY TICKET!" a dialog popped up asking if I want to use the FreeLOT coupon. 
NOTE: the dialog box should be slightly bigger to include all of "YES" "NO" selections.

The FreeLOT does not get reduced immediately after the purchase, but it gets reduced after a short while.

Now, let's see if this is my lucky ticket....

I had to retry several times to push the transaction through.
As you can see from my uploaded pictures, https://imgur.com/a/4T1QFFF (https://imgur.com/a/4T1QFFF) you can see my metamask wallet indicates 68450 LOTs where as etherscan https://etherscan.io/tokenholdings?a=0xc8c6618e0ffdb0fedb49385a3dc26845a2179865 (https://etherscan.io/tokenholdings?a=0xc8c6618e0ffdb0fedb49385a3dc26845a2179865) indicates 68050 LOTs.

Hello Sjyi!

That's really strange. Is there still a discrepancy? Because if so, it may be due to where MetaMask is looking for your LOT balance. The LOT smart-contract itself (https://etherscan.io/address/0xafd9473dfe8a49567872f93c1790b74ee7d92a9f#readContract) is the sole source of truth re LOT holdings. As such, whatever the balance the smart-contract says you have, is the balance you have.




However, this page (https://etherscan.io/tokenholdings?a=0xc8c6618e0ffdb0fedb49385a3dc26845a2179865) still shows your balance being lower by 400 LOT. It's almost certainly due to a discrepancy on etherscan's side, since every token transaction made with a non-ERC20 token show's this warning:


Which occurs because the LOT isn't an ERC20 token at all. The tokens are still transferred correctly, only a different event is fired in the LOT's ERC223's case.



Edit:

Upon visiting etherscan.io/address/0xc8c6618e0fFdb0feDb49385A3dC26845A2179865 (https://etherscan.io/address/0xc8c6618e0fFdb0feDb49385A3dC26845A2179865) - ie, your account's page, looking at the token's tab showed 68050 LOT. Then at the bottom, on clicking "Read Contract", and pasting your address into the "Balances" form, in order to query the actual contract, the contract returned 68450 LOT. And suddenly the value at the top also updated to read 68450 too!

This page (https://etherscan.io/tokenholdings?a=0xc8c6618e0ffdb0fedb49385a3dc26845a2179865) is still showing the wrong balance however. So it's definitely something strange going on via etherscan. Metamask clearly looks at this page too if it's displaying the incorrect, lower amount (which makes sense, not having to poll the chain...), and so was displaying the wrong balance in this instance. Not terribly user-friendly!

So, the take home message is that whatever the LOT smart-contract itself (https://etherscan.io/address/0xafd9473dfe8a49567872f93c1790b74ee7d92a9f#readContract) says is gospel, so don't worry, you have your tokens. W/r/t Metamask and the token page showing the wrong balance, we'll keep digging and see what we can find out...

This certainly was (or is) a difficult one to track down.  Glad you were able to track it down. Glad that you're on etheraffle team.

Noticed this tweet.

Excellent team meeting this afternoon - update will be coming soon! Meanwhile get playing and winning ETH at http://etheraffle.com . Have a look at http://etheraffle.com/ico  too to see why you should take part of the the only truly decentralized lottery in the world!


When will the "update" be coming?

Hi Sjyi

The update is still in progress - it grew larger than expected and so is taking some more thorough testing before going live...

I know setting up the development/test environment could take an effort, but if you're willing to take on remote test, I'm willing.  I'm starting to work with truffle.

Dev:

Came across this article regarding Solidity.  https://medium.com/@Hibryda/why-solidity-isnt-solid-3341af77fc1c (https://medium.com/@Hibryda/why-solidity-isnt-solid-3341af77fc1c)

This is not about etheraffle, but about Ethereum's Solidity.  Was wondering about this statement from the whitepaper "Provably Fair – Everything occurs in the public domain."  I know this is not my first encounter of "provably."  There are other projects with such a claim.  But with etheraffle having completed so much work, I thought you maybe in a better position to answer this question.  Have you carried out proving the fairness of etheraffle?  Is the "provability" based on analysis of theorem prover or based on the fact that all the transactions are recorded on the blockchain?

I know this question may go beyond the scope of this project, but it may be directly related due to the fact this project is based on Ethereum.

Thanks for your time and info.

Hi Sjyi!

With regards to provability, ours comes from the fact that the entire of the raffle functionality takes place on chain. This, in addition to the transactions also being etched in to the chain where our fairness comes from. Not only can you see how our random numbers are generated (by lightning no less!) but also how they are stored, how a users numbers are compared to the winning numbers, and how in the event of a win the prizes are calculated using the actual odds which are baked into the smart-contract. You can literally read the code that's running on chain and see what it's doing. We are hiding nothing.

Better still, because of the recursion in the smart-contract, you can see that none of the above requires any any human involvement at all. All the other blockchain lotteries out there obfuscate these processes, and or require a person (and so a centralized, single source of failure) to make happen. We do not. It's all laid out there, in the contract, for anyone to go and look at.




Very interesting! How familiar are you with Solidity development?

As it happens, we don't use the Truffle/Ganache frameworks due to the large overhead. The current contract re-write that the update hinted at earlier is now in a far more functional programming style (which strictness lends itself to blockchain security). And so because much of the contract has now been converted to "pure" or "view" functions they are much simpler to unit test directly in Solidity itself (or in Go when automating). Those functions remaining that do have side affects (mainly pertaining to Oraclize) are also simpler to unit test directly in Oraclize's forked Remix compiler.

Thanks for your explanation.  The fairness of Etheraffle can be "proved" by recordings of all operational aspects through the public ledger.  And also due to "no touch" flow fairness can be maintained.


Good to know that truffle/ganache frameworks come with a large overhead.  I have extensive system design/develop/testing/implement experiences but am new to Solidity.  As I have brought up many developers progressively regardless of their self proclaimed ability/knowledge, I also apply that to myself.  Assign a simple task and progressively assign more demanding tasks with each successful assignment completion.

As I witnessed this project to be well planned and backed by "provably" capable development team, I would be honored to be associated with the project.
