Android wallet update 3: Hi; Good news. I almost completed the POS-Secure transaction-tracking SPV wallet I described earlier. Though it proved itself to be a headache to implement, but it's all clear and working now. I haven't implemented POS difficulty calculations yet, but as the base is there, it'll be very easy to plug it in. And then it'll be easy to reuse POS difficulty calculations to implement stake generation later. Current status is, we have a working light verifying blockchain controller, and a memory-only storage for that, optimized for its needs (and designed for converting to disk storage). I had to change bitcoinj's primitive storage data structures for its own needs, but everything is simpler now than my first implementation for POS SPV. Next step is to make the storage on disk instead of memory only (I guess this will be finished tomorrow). Then implementing POS difficulty verification (1 or 2 days). The library will be secure when POS difficulty verification is done. Lots of testing would be required. Then smooth out the rough edges. Then binding the UI and release. (Minting only in the library level will come some point after POS difficulty verification, but I plan to do UI integration after the initial release) Regarding other paid POS wallet developments; frankly I don't believe someone outside the community just paid for the job would be able to finish this in a secure manner. POS coins are different animals, and a SPV POS wallet has much different security needs than a SPV POW wallet. The core of bitcoinj was implemented for a POW coin, and it was very hard to get to this stage. So my guess is that anyone getting paid for the job would implement it in the easiest way possible, get his money, and continue with his life. (That easiest way was working for Mintcoin 2 days after I started, but well, it was not secure, it was extremely easy to fool the wallet to follow a custom block chain). Still, marketing matters, I don't think most people will care if secure or not, and they will focus on being the first wallet. I'm trying to be quick. Android wallet update 2: Hello everyone; I'm progressing in the Java MintCoin library. I got the SPV wallet kit distributed with bitcoinj working (ForwardingService) , it can sync from genesis block to latest block (persists on disk). It can generate a MintCoin address, and receive coins sent to that MintCoin address and send a transaction back. It has some problems creating the forwarding transaction though, I haven't digged in that direction yet. My biggest concern is security vs. being lightweight enough for Android devices. Normally, SPV wallets are used in android wallets, which only store last x block headers (say 5000), and delete the rest. They trust on their peers and the cumulative POW difficulty of the chain. They don't verify any transactions. In contrast, for a POW+POS coin, header difficulty in POS blocks is not a secure measure at all. Difficulty of the header is relatively low, and easy to forge. The coinstake transaction of POS block provides block's security, and if you're not verifying transactions, you will have problems. So, if you know that your peer is not validating any transactions at all, including coinstake, you know that you can forge a series of POS blocks and send it to your peer. (In order to be able to verify coinstake transaction, you need to have stored the corresponding transaction that generated it from at least 20 days ago. Its time open ended actually, its position can go up to genesis block. In contrast SPV clients only store transactions that relate to their own addresses, and discard the rest) Currently, I'm working on a lightly-verified SPV blockchain implementation. It stores up to 40 days of blocks and tracks spent/unspent transactions seen in these blocks (this would somewhat affect the resource usage, but not as much as a full verifying blockchain which is almost impossible to run on android devices). As transactions of last 40 days would be always available, client would be able to verify a high percent of generated POS blocks (If they are indeed generated from unspent transactions, and if coin's owner really matches). It won't be able to verify POS blocks that are generated from older transactions. So this is a mixed approach, although it doesn't verify all POS blocks, it would assume that a few unverifable POS blocks followed by a large number of verifiable POS blocks means that the network accepted the questionable chain, and that chain can be trusted as long as the network does. Actually this is not a verifying implementation, but rather a invalidating one; detecting as much invalid POS blocks as possible before they are appended to any chain. This implementation is somewhat different than current bitcoinj/mintcoind 's transaction input/output connecting (they keep track of transactions spent only in the main chain, and rely on cumulative Proof of Work on alternative chains. They do a transaction reordering every time an alternative chain becomes longest). They can do this because they can verify any chain at anytime, they keep the whole history, they don't have any risk at all. In contrast POS with SPV has to keep track of spent/unspent transactions outputs in every possible branch simultaneously, so it can reject invalid POS blocks even before they end up in an alternate chain. This difference proved itself to be highly challenging to implement, although I believe I managed a way out. So, well, I'm continuing working on this hard, and I believe I resolved most of the problems. Although library is currently working and able to persist on disk and receive transactions, it is not secure until this light verification is done. Hopefully I would be able to fully implement this by the weekend. I'm working on github, I decided not to publish my changes to public until I can get a wallet android app working, so I avoid pushing my changes there. I'm currently only working only on the java library, it will be very easy to port any wallet to use it once library is properly working. But I don't want any other PoW+PoS coin to grab the library (even unsecure versions of it) and release an android app before us. I really need some comments / feedbacks on my solution to POS Coin + SPV wallet security issue -- so if you think you have an idea, don't hesitate to contact me, I'll be happy to find out potential security issues and change the design before it's late. Android wallet update: Hello everybody; I'm working on a Java MintCoin library and an Android wallet. For best security and long term development, I forked from latest bitcoinj last week. Converted it to Scrypt. Made it able to communicate with my local Mintcoin wallet over network. I just updated it to understand and accept PoS/PoW hybrid blocks, and I can announce you that it can sync with the blockchain from genesis block up to #239870, which is generated just minutes ago  There are some missing features yet: - It can validate PoW block difficulties (calculation is a little different in PoW/PoS hybrids than pure PoW coins, PoS blocks affect calculations, and modifying bitcoinj library for this task really had some challenges) ; but it doesn't try to validate PoS block difficulties yet (this is a security issue and will be fixed before releasing) - It doesn't verify POW block rewards (due to the fact that I couldn't find a specific pseudorandom generator implementation that decides on randomized POW block rewards). I don't think this would be an issue as the main use case would be a Simple Payment Verification wallet, checkpoints will cover our security up to removal of PoW from MintCoin (though it will be nice to have the checks in place) - Minting: It's now almost clear that minting would be possible even in SPV wallet mode. I will annonuce details later. I have to figure out validating PoS blocks first. - UI: I'm just trying to get the pure library working properly now. Once the library is working, it'll be very easy to fork/make an Android App that uses it - Bloom filters: Here is a request for the community: Current Mintcoin wallet doesn't support Bloom filters. Bloom filters allow SPV clients download only the transactions they're interested in (instead of all transactions in blocks), reducing mobile users' data usage dramatically. Please put a bounty on it so that someone can merge it from bitcoin client. Android wallet will work without Bloom Filter support in the main client, but its data usage would be much more. This is excellent news! Sending a tip! |

So this is a copy of fluttercoin.. with an IPO? You just changed the name of proof-of-transaction to proof-of-reward? Or is there something fundamentally different? If not, I think you should at least give fluttercoin credit and call it what it is, proof-of-transaction, instead of trying to re-brand a process that somebody else developed. You don't see people going around making PoW or PoS coins and calling the reward system something else.

...and what will happen when this guys will dump all their BC ?  1 BKamGtcg6Cwe6f3zy2AmFsaxN1PwNSF2Cv 3 000 000.00000000 bc (1 300.50 btc / 640 887.70 usd ) 2 BKYCpC6yttWiJ8fk6fHbQvLoqC6oc1Q4rb 3 000 000.00000000 bc (1 300.50 btc / 640 887.70 usd ) 3 BJ2y2twPhc1taeuJcQrjdxjuz7qDZGQzAh 2 236 983.22656154 bc (969.73 btc / 477 885.01 usd ) 4 B7nvWE1M7prrVpoC5ddkQ1kv3TFSKmYsEb 1 915 523.39053670 bc (830.38 btc / 409 211.79 usd ) The first two are exchanges. Secondly, these guys didn't get to be large holders by doing stupid things. They paid big money for this investment and are not going to flush it away. Why do exchanges store a huge even number of coins at a single address, where no coins seem to be going in or out? I mean, those top two addresses shown above each have only 1 transaction in (on the same day around the same time for both addresses, about five minutes apart) and 0 transactions out. |

The price has been stable for quite a while. retailers and consumers like price stability. How would you like to buy a card and pay 10.00 then the next day you find out you paid 150.00 for the same card?
Well if that's the case and u want the price to be where is it now and that it stays here, then i have to apologize u guys, i truly am sorry to bother u with my ideas, for bringing the price of the coin up. Hi, me and couple of guys on mintcoin irc r thinking to jump start mintcoin but we should put together some donations for 50-70 BTC to buy out that wall on mintpal. I know u all have millions of mintcoins witch u know what u can do with them at the current price. I know it's a long shot but it's worth to give it a try, what do u think?
I welcome your efforts if they are sincere, but this makes absolutely no sense and as such, is very suspicious. You cannot buy Mint with Mint.. If you wanted to buy up the sell walls you would need BTC. Besides. Building up enough BTC for a one-time break of the sell walls is not a sustainable means of raising the price anyways. It is much more important to focus on the value and utility of Mintcoin instead of the price. |

Look at staffly's post history, they are all about cinnicoin. A coin that is mined over 3 days... lol. instamine, anybody? People talk about how PoW is the most fair form of distribution, and perhaps that is the case- but most certainly not if the PoW phase only lasts a few days to a week. Completely absurd.

"Not staking because you don't have mature coins" - What are mature coins, and do I need to have my wallet open to be 'earning' PoS?
30 days and yes, needs to be open. There are bounties I think for guides if anyone wants to claim them I think What happens if I have my wallet open for say 28 days and my computer crashes, is down for 10 minutes and I fire back up. I have to wait another 30 days? The coins are never actually in your wallet, so to speak, they are always "on" the blockchain where they are assigned to and accessible only through the private addresses that you hold in your wallet.dat. As such, your coins age whether or not your wallet is on/open. You only need to open your wallet when you want to stake coins that have reached maturity. So you don't need to leave your wallet open for 30 days, you just need to open it for a few hours thirty days from when coins were deposited at your addresses to allow those mature coins to find PoS blocks. |

"Not staking because you don't have mature coins" - What are mature coins, and do I need to have my wallet open to be 'earning' PoS?
By mature coins, it means coins with enough coinage to stake. I can't remember what the minimum coinage for staking is for flutter, though. Somebody help me out on that. Your coins earn coinage on the blockchain, whether or not you have the wallet open, but once coins have reached the age to stake you need to open your wallet to stake them, and leave it open long enough for them to find a PoS block. |

Price value will drop, don't buy now ...
all you do in this site is copy paste this into all altcoins topics ?  Looking at his post history is very humorous |

Mint community are welcome here if they are fed up of their coins Don't be too offensive with them Art of War guys We need troops and allied Hope Mintpal will add a exchange BC/DOGE I really hope Doge community join us The coin who attract the Doge community have the greatest chance to win at the end I don't like the word Operation so call it the Black Dog team  Do what you can to get them here  Instantly thought of this  https://www.youtube.com/watch?v=Fgm7F30EN50&feature=kp |

How can their be so much volume in Fluttercoin and how can it be so much talked about on twitter by those pumpers who are holding it.
And how can this coin be soo good and yet just not move?
Every time it drops down to 1700 its a fucking bear trap so why the fuck are those whales doing it while they keep the coin so low.
Dont get it
Because the buyers fade away at the higher price, likely to drive the price down (or anticipate the price drop), they are essentially undecided on price, we tested 3000 on cryptsy yesterday and a little less on minptal, and there was lots of selling. If the market breaks the highs on all exchanges likely we will see 3500 and likely settle around 3100. Thats my opinion at least Oh wow we hit 2700 high on mintpal last night O.o like almost every night it happend.. And here comes the ussual fluttercoin dump down the 2ks again........ wonder how many hits of these it can take I have a feeling that Blackcoin can hit 1 dollar with so much easyness... If peercoin has a price of that. I mean come on. No other coins can be mined. And seriously. Even after that hugee dump. So manhy new people want to get on board.
And another seriously.. If you ask merchants to add Blackcoin or Fluttercoin as a payment.. Wich one do they likely chose just based on the name that sounds better? And fuck me men, this community has over 1000 posts here.
The coins will become rarer and rarer. Its special. All other coins with their new features and everything are just.. Pumps. Fluttercoin will probabbly get a pump up to 10k. But I have a feeling that Blackcoin might just break out up to 1 dollar before that.
And can SOMEONE PLEASE TELL ME why Darkcoin can make it to a dollar but Blackcoin has not?
Maybe you should just stick with BC? I don't understand the point of your comments here. You expect the "moon" overnight? |

Fuck it! 178M Mint is not a reasonable amount to ask! Case closed! People who sent to the donation address before Saturday 4:47 PM GMT will be refunded.
:Pwhy you recognize it so late?? Nobody knew they wouldn't extend the deadline until a few hours ago |
|
|
|
We pay when we estimate it is fair. That amount+deadline mix doesn't seem fair to us...
Then, why you posted it here? It is fair for the community to send MINT to them but not fair for you I saw the news on Twitter, and just reported it here and everywhere. After clarification, that no longer seems like a good move. I might remove everything about CoinKite if everyone agrees we won't do it. Then, please refund the guys that sent their MINTs to them. I am not one of them, but I think you made them to send their MINTs somewhere you proposed without doing your study beforehand. You can find the transactions there http://mint.blockx.info/get/address/MdJjejnLrSVe1TwWCMDRmHgWiTnMyHcEiEWe are talking for about 3.3M MINT due to your error. With all due respect, mintcointeam did not make us send coins anywhere. They simply told us about an opportunity and we acted upon it. With coinkite not allowing for an extension of the deadline, meaning Mintcoin only has 13 days to achieve the goal versus the 3 months the other coins had, I don't think the amount+deadline is fair either. |

Price value will drop, don't buy now ...
looking through your post history.. how often do you come here to say that exact same thing? multiple times a day? |
|
|
|
Beaver, you have it backwards lol. Coinkite is going to make all the money by processing payments. They are charging you so they can make double money it's absurd lol.
Can you think of an alternative service of comparable significance, which is available by other means? Coinkite enables any retailer to accept BTC, LTC and soon BC as a payment method. Being the next coin alongside BTC and LTC on their service could be very, very beneficial to MINT if coinkite took off. |

Guys, it's time to break the 40k wall.
You do know given what has happened today, the fact that we are still at 38K is a major victory. What did happened today? Don't you watch Harry Potter? This-Coin-Must-Not-Be-Named started trading on MintPal. I'm somewhat disappointed that Mintpal decided to add it as one of their personal choices... I guess I can't blame em though, they wanted the volume. |

I just got this from WC forum Thats great. Really great, BC guys haven't make this yet. Theres also a POS wallet being develop by Mintcoin comunity, maybe we can join efforts If you want us to help with your development we are there with you. We are all about technological progression here is our details: https://twitter.com/RaxeSoftwarecontact@raxe.ioSkype: raxe.io (Raxe.io Support) Maibe we can work with them together Interesting. I wonder how far along they actually are. Paspi may very well be ahead of where they are in the process. Do they have anymore details other than screenshots of a BTC android wallet (which says nothing about the state of a PoS wallet)? Also, are they referring to an android wallet that has complete PoS functionality? Just curious because they aren't clear about that. |

Part of the problem might be that there is just not a lot of understanding about PoT yet. Listening to the chat in Cryptsy, you hear all sorts of nonsense about how the coin is just a generic Scrypt clone, or how the logo / name sounds effeminate (Twitter notwithstanding), and in the absence of a good solid "What is the big deal about PoT?" diagram or article or even better, video, FUD jumps in to fill the information gap. There's already someone trying to post some article about how PoT is broken and won't work, and though I haven't seen it it is almost certainly going to be followed by more. This is mostly because of the information gap that exists. @TheKidCoin, do you have any interest yet from high visibility places like CoinDesk or Bitcoin Magazine looking to talk about PoT? I'd be willing to contribute a 1000 FLT towards a bounty to create a simple "average joe" explanation of PoT and why it works. Something like this: http://2.bp.blogspot.com/-kMsHx8DwsrM/UngH09tltpI/AAAAAAAAAXU/jCt_qqIARsI/s1600/Bitcoin-infographic.pngI agree! Fluttercoin and PoT need/deserve more publicity. |
