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.

Hi Sjyi

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

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 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 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 - 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 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 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...

Hi egretia

Thank you for your kind words!

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! Let us know how it goes!

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...

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

Hi Sjyi!

The article we posted yesterday here 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.

Quick update - we've implemented our random number picker AND made it more obvious per Sjyi's feedback!




You can read more about the update here!

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?

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

Hi ayisganteng

Thank you! We hope it's successful too!




Hi sjyi

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

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!

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?

Hi quockiencoltd

Glad to have you on board! Let us know if you have any questions!

Hi yehor

The team and so the company (for now) are located in the U.K.

Hello assasin21rus!

Thank you for the good question! Here is how we feel about the matter:


Firelotto are indeed our competitor, but we don't think they can compare to us at all. For a start they take a large cut of every ticket for themselves meaning smaller returns for investors.


In addition, there is every chance that  Firelotto steals your dividends and winnings which they can easily do because they are completely centralized meaning that you have to trust them with everything, unlike with Etheraffle.


They also don't publish their smart contracts meaning you are at risk from a Firelotto exit scam & them running away with all your money.


Their token doesn't pass the Howie test and so will be viewed as a security when the time comes, and so possibly illegal.


Their company representatives didn't know the URL to their own Github when we met them, and then later thought that showing us some javascript was the same thing as them showing their smart-contracts. If you read their ANN thread you will notice worrying concerns about their leadership and past scams they have been involved in, as well as them failing to pay out winner's prizes in a timely fashion, if at all. Our raffles are automatic, unlike Firelotto, meaning you withdraw your winnings whenever you want!


And worst of all, it seems like Firelotto are driven purely by greed since they take 10% for themselves and give nothing to charity! Our goal is to give as much to charity as possible! So we take 0% for ourselves!


In fact, we compared ourselves to a few other blockchain lotteries too and this was the result:
