Welcome to our seeding event for Crash launching in Beta this week. We are seeding it similarly to RHavar and others so it should be fairly straight forward.

To prove our fairness we have generated a chain of 10,000,000 SHA256 hashes where each hash is the hash of the hexadecimal representation of the previous hash. The last hash in the chain is: 78a9757d3be42b74a3f70239078ad9317125fe9ee630d5bdada46de963e56752

The formula for generating the game result:

Code:

const gameHash = hashChain.pop()

const hmac = createHmac('sha256', gameHash);

// blockHash is the hash of bitcoin block 584,500

hmac.update(blockHash);

const hex = hmac.digest('hex').substr(0, 8);
const int = parseInt(hex, 16);

// 0.01 will result in 1% house edge with a lowest crashpoint of 1 

const crashpoint = Math.max(1, (2 ** 32 / (int + 1)) * (1 - 0.01))

blockHash used is Bitcoin block 584,500 which has not been mined at time of posting. Basically we are using the hash of a future bitcoin block as a client seed so players can be certain that we did not pick one in the house's favor. I'd appreciate it if someone could quote this post so this is all set in stone.

Excited to show you all Crash very soon!

edit: nevermind... had a bug in my code.

Excited to show you all Crash very soon!

Really excited to see that you guys keep on innovating and come up with new games every time, you were settled with primedice for sometime and now stake with many games and options and now another one to keep the fans entertained and i hope you could make it the one stop shop for all gambling if you include sports book to it as i have heard that you are working on it but not seen any official confirmation regarding that.

That is my preferred choice of gamble. It's pretty close to completion but we want to make sure everything is perfectly polished, I'll have more news soon

Right now users are beta-testing Crash, we will have a full launch Monday!

Hi guys. I'd love to see Crash on Stake, I'll keep an eye out. But I have a question that might seem dumb. Can anyone point me to an article or post that describes the ins and outs of a seeding event? Things like what a secret is, why it is used, how the algorithm that converts game hashes to game results, or what the algorith even is? Or how a game maps to a hash in the chain and how does one verify the hash with the code you gave here? I think a concise post regarding this would be great for the average non techie like me to understand how provably fair games work.

Hi there stake dev here,

Im thinking of posting a live coding video where i go through the system and explain the fairness. If there's interest and I get some time I will post it.

The basic idea of the hash chain is that each 'link' is the product of hashing the previous link. the sha256 algorithm is very common in programming and there are plenty sites/tools you can use to try it out.

the basic idea:

startingHash -> hash startingHash = hash1

hash hash1 = hash2

hash hash2 = hash3

etc...

so we did that 10 million times, and showed everyone the last hash in the chain (hash 10 million). Then once the first game has ended, and the hash for that game (hash 9,999,999) has been published you could hash that once and the result would be the original hash that we published on here. then after 1 million games you could get the hash for that game, hash it 1 million times and again you would have the original hash posted here.

Any way that's just a really quick and dirty explainer. ill post the video in this thread when i get round to making it.

cheers

This probably won't happen because its rare, however what will you do if block 584,500 turns out to be an orphan.

So far in 2019 it looks like only there was 4 orphaned blocks but it does happen from time to time.
https://www.blockchain.com/btc/orphaned-blocks

So will the first valid block 584500 be the one with the true hash or the block which eventually gets included in the chain?

It has been mined! and our client seed is in!!

I am one of many fan of stake.com because all we know that they already stand for their tag line that they is the fast growing online casino. But I think their good image was broke from the time that they bounty manager was change and break all campaign agreement between bounty campaign and bounty huntrers because there are so many bounty hunters was disappointed on that incident and issue.

I miss dooglus

stunna, you going to get into making dapps for PD and stake.

.

you should if you want make x3 more money then you do now

also use tron for your dapps. tron will be the leader in dapps
