Title: ANN- The 1st blockchain Lottery | P2P Lottery | open source Lottery Launched...
Post by: vpncoin on May 11, 2015, 08:20:57 AM
Hello everyone, Today I am pleased to announce that we create a based on blockchain's P2P lottery, it is open source. We call it BitNet Lottery, we plan to launch it at Vpncoin's 320000th block. Source code: http://github.com/bit-net/vpncoin Windows qt version: https://drive.google.com/file/d/0B7Kd-l4hTU3GV3o4WG5LZjd2Uzg/view?usp=sharing Because no one can customize a future block's HASH, so, blockchain's lottery is fair and equitable.BitNet Lottery is a transaction, it comes with specific transaction messages and stored in the block chain. Below is BitNet Lottery Format Description:Lottery Flag | Lottery ID | Lottery Type (Genesis = 1, Bet = 2, Cash = 3) | Bet Type | Bet Amount | Mini Bet Amount | Start block | Target block | Guess HASH Length | Bet Text | Lottery wallet address | Lottery wallet Private Key | Bettor's default Wallet Address | Lottery Tx ID | Sign message For example: Genesis Lottery https://i.imgur.com/mxn1wmH.jpgBet Lottery https://i.imgur.com/heLsU3e.jpgBitNet Lottery: | 00000000E3C9 | 2 | 1 | 100 | 30 | 305048 | 305068 | 3 | 26 | VtV3QA45Cd6wNbgQsZoGaxTPoJzMKrtmpK | 0 | VevimYsrNKWbx2W6Bnq2qyLthcnEasLMTg | ed88213480fa502936141016b912c920a43c488e7b9045605fa945b61c74493f | 0 Parameter 1: BitNet Lottery: BitNet Lottery flag Parameter 2: 00000000E3C9 BitNet Lottery serial number Parameter 3: 2 BitNet Lottery type, Genesis BitNet Lottery = 1, Bet BitNet Lottery = 2, Encash BitNet Lottery = 3 Parameter 4: 1 betting type, Guess a future block's hash(last N byte) = 0, guess a future block's hash(last N byte)'s digit value = 1 Parameter 5: 100 bet amount Parameter 6: 30 minimum bet, the player bets must >= this number Parameter 7: 305048 BitNet Lottery start block, Parameter 8: 305068, BitNet Lottery target block, the answer from this block, Parameter 9: 3 guess the last N characters from the target block Parameter 10: 26 betting number Parameter 11: VtV3QA45Cd6wNbgQsZoGaxTPoJzMKrtmpK BitNet Lottery wallet address Parameter 12: 0 BitNet Lottery wallet address's private key, BitNet Lottery Type = 1 (Genesis BitNet Lottery) must be specified this, when encase, player need to import the private key, and then send coins from this address. Parameter 13: VevimYsrNKWbx2W6Bnq2qyLthcnEasLMTg bettors wallet address, if winning, prize will be sent to this address. Parameter 14: ed88213480fa502936141016b912c920a43c488e7b9045605fa945b61c74493f betting transaction hash, BitNet Lottery Type = 1 (Genesis BitNet Lottery) is set to 0, BitNet Lottery Type = 2 (Bet BitNet Lottery), is the "Genesis BitNet Lottery" transaction HASH (tx id), BitNet Lottery Type = 3 (Encase BitNet Lottery), is the genesis or bet transaction HASH (tx id), for prove the player is betted. Parameter 15: 0 use "bettors wallet address" signature "betting transaction hash"'s text, BitNet Lottery Type = 3 (Encase BitNet Lottery) must be specified this, to prove that the player is "bettor's wallet address"'s owner, other Type set to 0 How does it work?https://i.imgur.com/Yrta4jK.jpgSome people think that use 51% attack will break our lottery rules, this is not established. Because, in the valid bet block range, you do not know the answer, when you use 51% attack get the target block, you will lose the opportunity to bet, no one can be insert a Bet transaction into an existing block. So, our rules are valid. We add some codes in main.cpp to check every transaction. If the tx's transaction message field include BitNet Lottery flags, will check its legality. bool IsStandardTx(const CTransaction& tx)

Because no one can customize a future block's HASH, so, blockchain's lottery is fair and equitable. If the lottery reward became greater than the block reward, then mining pools would have a very strong incentive to ensure that they win. The way they could do that (assuming 50% of network hashing power or more) is they would mine the block, check if they won the lottery and if not, then discard the block and try mining another block with a block hash where they win the lottery. If the major pools collude together to do this (lets say, 90% of hash power). Then it would be fairly trivial to increase your chances of winning by at least 9 times. (you would get at least 9 "draws"). Also, there is more evil that lurks under the covers. With 90% hashing power, you could orphan off a winning lottery block by going backwards in the blockchain and mining old blocks again (with timestamp manipulation so your blocks are more difficult and thus better). Cool idea, but it has serious security implications and will not work. All of this applies also to basing the lottery on a Bitcoin block hash as well, though your lottery would have to be really valuable to get Bitcoin mining pools to care.

Hello, Maybe you not read our codes, We use a future block as target, no one know the answer, so your say "check if they won the lottery and if not" is not established. And we set bet block range is "Start block number + 1" to "Target block number - 3", Maybe Someone can control the next one block, but no one can keep a block to future + 3. Thanks.

Because no one can customize a future block's HASH, so, blockchain's lottery is fair and equitable. If the lottery reward became greater than the block reward, then mining pools would have a very strong incentive to ensure that they win. The way they could do that (assuming 50% of network hashing power or more) is they would mine the block, check if they won the lottery and if not, then discard the block and try mining another block with a block hash where they win the lottery. If the major pools collude together to do this (lets say, 90% of hash power). Then it would be fairly trivial to increase your chances of winning by at least 9 times. (you would get at least 9 "draws"). Also, there is more evil that lurks under the covers. With 90% hashing power, you could orphan off a winning lottery block by going backwards in the blockchain and mining old blocks again (with timestamp manipulation so your blocks are more difficult and thus better). Cool idea, but it has serious security implications and will not work. All of this applies also to basing the lottery on a Bitcoin block hash as well, though your lottery would have to be really valuable to get Bitcoin mining pools to care. Hello, Maybe you not read our codes, We use a future block as target, no one know the answer, so your say "check if they won the lottery and if not" is not established. And we set bet block range is "Start block number + 1" to "Target block number - 3", Maybe Someone can control the next one block, but no one can keep a block to future + 3. Thanks. Let me break it down into Chenglish for you. Miner make block future + 3. He no win lottery with block. he decide not to publish block. he mine new block. he get second chance at lottery. he maybe win. unfair for people not miners. Vpncoin is a PoS coin. We set bet block range is "Start block number + 1" to "Target block number - 3", For example: Lottery's "Start block number" is 100, "Target block number" is 200, the valid Bet block range is 101 ~ 197, And current block number is 196, you can DIY block 197, but our target block is 200, and when current block number > 197 every betting is invalid. I know your mean is 51% attack? even you do that, it is also under our Lottery rules. Why? Because You cant know a future (target) block's hash, when you get the target block, you can't bet, it's under my rules. Bet is a transaction, it must Stored in a block, you need think about this. Like this: https://i.imgur.com/SkZOe1S.jpgThanks.

seems good. but please take a look around NAScoin , its Lottery function have been launched a year ago but still dead already. that means Lottery is not fit for us.
If you read my idea, you would not say that, thanks. Could you please elaborate more, in a less technical way? :)

BitNet Lottery Bet block range: "Start block + 1" ~ ("Target Block" - 3), To prevent cheating.
BitNet Lottery Encash must wait current block big than ("Target Block" + 3), also is to prevent cheating.
Some people think that use 51% attack will break our lottery rules, this is not established.
Because, in the valid bet block range, you do not know the answer, when you use 51% attack get the target block, you will lose the opportunity to bet,
No one can be insert a Bet transaction into an existing block.
So, our rules are valid.
