Another week is coming and with it the end of another successful gleam contest hosted by our platform. Much like Nakamoto previously, DecentraWeb gleam has ended with a staggering number of participants.

We are truly happy to see our community blossoming this way, and taking advantage of the opportunities we are trying to provide to everyone with our Gleams contests.

The lucky 40 winners were drawn from a huge pool of 7782 people, once again showing the faith you have in us and in the choice of our projects. And we can’t be happier than that, since you recognize the value we are bringing to the public eye, with DecentraWeb being one of the most needed tools to get back some of the freedom the internet was born to provide.

The value of being able to create your own Domains without the need to pass through one of the giants that are holding the reins of the web can’t be understated, and DecentraWeb has found yet another key use-case for block-chain technology.

Their vision is one truly in line with ours, with the end goal of a free, fair and decentralized web, able to give the same opportunities to everyone, instead of the mish-mash of tech companies and monopolies that it has become in the last ten years.

But enough talking about things that you all are clearly aware of. We are proud to see that our community recognizes the value of what we are doing but we are not only here to say how much you mean to us, we are here to announce our winners!

So let’s stop dilly-dallying and check the list below. Best of luck to everyone that missed out this time, we are sure that in the near future everyone will get a chance to have his name on our winner-lists!

As always, we will be also showing our selection process for full transparency of all proceedings.

STEP 1 SPREADSHEET CREATION

We prepared the spreadsheet containing every person who registered using Gleam and passed the KYC process. The spreadsheet includes three columns:

  1. Assigned consecutive number
  2. ERC20WalletAddress
  3. Points (Total points)

You can find a CSV under the link below: https://docs.google.com/spreadsheets/d/1QuDQccFcAqrPjY-PzlGBaSYDgIDBPK6fMu-Eh2ccjso/edit?usp=sharing

STEP 2 PUBLIC HASH

To dispel any possible doubt, we are publishing the SHA256 online hash file checksum function. Anyone is able to check the hash value — this proves that the data has not been tampered with.

You can check it by yourself, for example using PowerShell, or any other SHA256 :

Get-FileHash .\fileName.csv -Algorithm SHA256 |Format-List

STEP 3 GITHUB.

We used a contest selection contract that is available to check on our Github repository under this link: https://github.com/GemStarterIo/whitelist-selector/blob/main/contracts/ContestSelector.sol#L108-L138

The contract is verified and available to check under this link: https://polygonscan.com/address/0x97627898d3bac6fe54de88a2d7f5a64e20024ba2

The contract is keeping links to the Google files with data included in the CSV file as well as containing a SHA256 hash of the CSV file.

STEP 4 HOW DOES THE SMART CONTRACT WORK?

The contract asked Chainlink for a random value

Based on a random value, x unique numbers in the range from 0-to-n were generated

Where each new unique number was also a new random value for the function, and n was the number of participants who registered and passed the KYC process.

winnerSeed = uint256(keccak256(abi.encodePacked(previousWinnerSeed, i, nonce)));

winnerIndex = winnerSeed % kycCount;

STEP 5 SELECTION

Using the contract, we were able to select: 50 random numbers matching the numbers from the CSV file, where the winners were the first 40 unique ERC20 addresses.

Everything is verifiable on-chain, links to transactions are posted below.
