SweepstakeCoin (SWEEP)

\

***** Please go to New thread: https://bitcointalk.org/index.php?topic=2112735

***** this thread is closed.




**Version 1.3 is released. Version 1.3 added checkpoints to resolve fork issue. It is a *mandatory* upgrade, so please upgrade as soon as possible. Sweepstake feature is temporarily disabled. Once the blockchain is stablized, we'll restore it. Thanks.**

About SweepstakeCoin

SweepStakeCoin (SWEEP) is a new PoW/PoS coin with many nice features.

- It integrates and enhances the sweep stake features originally defined in JackpotCoin;
- It integrates natively with TOR, so all the connections and communications in SweepstakeCoin automatically happen through TOR, thus protecting your privacy, and no client side set up needed;
- It also uses JHA algorithm for PoW. JHA (JackpotCoin Hash Algorithm) is an advanced algorithm similar to X11, but enhanced with energy saving and better security. There is no ASIC available for this hash algorithm, so as opposed to X11/X13 etc where ASICs are available, the use of JHA will ensure that we have a fair mining environment with GPU/CPU.
- It also provides integrated encrypted messaging.

All the above features are provided at the launch time, and the dev team will continue developing and enhancing the coin.

Sweepstake Details

SweepStakeCoin creates sweepstake for everyone who mines to get a chance to win big. The sweepstake will start at 50X of the normal block payment, and increases exponentially with the time. When the elapsed time reaches 5 days, which is the average expected time to win, the sweepstake will grow to 1,000X the normal payment. If still not won, the sweepstake will continue to grow with the time exponentially, until it reaches 10 days where the sweepstake will increase to maximum 20,000X the normal block payment. After 10 days, the sweepstake will stay at 20000X the normal block payment until won.

The formula to calculate the sweepstake is:



For example, if the normal payment is 1000 SWEEPs, and you win the sweepstake at 7th day 16 hours, the sweepstake payment will be
    1000 * (50 * exp(c*7 2/3)) = 4,941,772 SWEEPs

The payout curve is shown in the following diagram. Note that this is an example where the current block payout is 1000 SWEEPs.



You can check the current sweepstake size using the client. Open the wallet and go to Help->Debug window->Console, type getcurrentsweepstake, you will see the current sweepstake size.

Also the sweepstake is determined with true randomness, so no cheating from big hash powers.


Native Integration with TOR

The code-level integration with TOR ensures that we are always in an secured environment. There is no client side configuration needed. The Client will automatically join the TOR network and connects to the other TOR nodes in the network (including our seed nodes). After you connect to the SweepstakeCoin network, check your displayed IP using SweepstakeCoin client console, you will see that your client is assigned a hidden TOR address (onion address). See the following screenshot.





JHA Hash Algorithm

This hash algorithm is designed by JackpotCoin team and has many advantages over the conventional hash algorithms. Notably:
- No AISC Available
- Energy Saving
- More Secure

The following is a excerpt from the original description of the JHA.

"JHA has designed using Random Hashing Method and Random Variable Hashing Round using SHA3, Blake, Grøstl, JH, Skein. It achieves the highest Secure Level without increase the requirements such as electric or hardware cost. It is permanently ASIC resist because there are multi-level of anti-parallelism in instruction, sub module, even full rounds of hashing... JHA uses variable random hashing rounds, it reduces the hashing power requirements by 1/2 comparing with the linear hashing method. And it increases 16234 times on the security side."

Bootstrap file - if your wallet not sync or you want quick sync, use bootstrap.dat (updated to cover to block 81250)

https://mega.nz/#!5xIkBBAA!0EOAtXHhmPxZjcaGwMRKtqWZJd0e991A1Ab15BX8cy4
https://drive.google.com/file/d/0B5nPUzyLr7_ITnJZaVlhVnA2RWs/view?usp=sharing

To use bootstrap file, download and unzip the file, exit the client. Locate your config dir. Make a backup of wallet.dat in config dir.
Then remove everything in your config dir EXCEPT wallet.dat, peers.dat and SweepstakeCoin.conf (if you have one). Again DO NOT
remove your wallet.dat. Now copy bootstrap.dat to your config dir, then start the wallet client. Now your wallet should say importing
blockchain from bootstrap.dat. Wait for it to finish, and you should be in sync.

Also pleazse temporary disable the staking (put staking=0 in conf file), once the blockchain stablized, you can restore staking.

Frequent Asked Questions:

Question 1: There are many altcoins now, what's special about this coin?
Answer: This is the first coin that provides sweepstake features and entirely running securely on the TOR network, so completely protect your privacy.

Question 2: Why do you not do ICO or crowd funding?
Answer: We believe that the dev team should only get reward if the coin is successful. Many upfront ICOs do not encourage dev team to stay on for long term and develop the coin, instead they often take the proceeds and do very little to nothing and sometimes disappear. We did a small premine of the coin, to encourage dev team to stay for long term and committed to the success of the coin.

Question 3: How do I know what is the current sweepstake size?
Answer: Open the client, and go to Help->Debug Window->Console, and type "getcurrentsweepstake", you will see the current sweepstake value.

Question 4: Why I see in Console window with getinfo that my IP is 0.0.0.0?
Answer: It could take a few minutes before the full connection with TOR network be established. So wait a few minutes and check again, you should see your IP address is a TOR address (end with .onion).

Question 5: How do I use linux daemon client?
Answer: to use daemon, first create a conf file named SweepstakeCoin.conf in the config dir, which in linux usually will be under ~/.SweepstakeCoin. In the config file, you need to put these lines:

Quote
testnet=0
listen=1
maxconnections=30
daemon=1
server=1
rpcuser=your-rpc-name
rpcpassword=your-rpc-passwd
rpcport=17571
rpcconnect=127.0.0.1

then start the daemon by typing "./SweepstakeCoind", the daemon will starts and running on the background. Once daemon starts, you can check status, for example "./Sweepstakecoind getinfo", "Sweepstakecoind getcurrentsweepstake", "Sweepstakecoind getpeerinfo", etc.

Question 6: Are you sure the sweepstake is true random and that people can not cheat?
Answer: Yes the sweepstake is true random. This is how it is done: we use a sub-string from the current block hash to compute whether the current block wins the sweepstake. Sub-string in the block hash is true random and there are statistics to show it (and can be easily demonstrated too). The problem is that the current hash can be only computed once the block is generated, and the payment to that block is already determined at that time. To get around this problem, we always pay the current block with standard payout, but if the current block is a winner of the sweepstake, we remember the payout address, and next block we add the difference between sweepstake and standard block payout to the payout and send to the same winning address. This way, the true randomness is guaranteed as whether a block is the winning is determined only after the block is generated, so there's no cheating possible. This ingenious algorithm was first proposed in a coin called Grain, many years ago.

no need. just download or build the client, start it, it will automatically connect to the coin network through TOR seed nodes.

It is estimated based on all the parameters, you can calculate yourself, lol

Thanks. Yes the maximum possible sweepstake is 20,000 times current block payment, which for now is 20,000,000 SWEEPs. Good luck!
