Good news!

The following is the first transaction ever received and forwarded by mintcoinj Cheesy

What's included & currently working in mintcoinj:

  • The first POW+POS java bitcoin library
  • A TxTracking blockchain & blockstore implementation: a compromise between Full Pruned Block Chain and SPV Block Chain
     
  • Like a Full Pruned Block Chain, it keeps track of ALL unspent transaction outputs since genesis block. Removes unnecessary old data.
  • It only verifies scripts of coinstake transactions (1 coinstake per POS block), so CPU-wise it is light-weight like a SPV Block Chain
  • Unfortunately, it is not as lightweight as a Simple Payment Verification system, but technically there is no way to make bitcoin-SPV style for a POS coin security-wise.
  • Processed data holds around 67 mb on disk (as of block 343262).

  • Proof of Stake Protocol (PPCoin v0.3) : 
     
  • Blockchain calculates stake modifiers correctly
  • Blockchain calculates and verifies stake hashes correctly (Modifiers mentioned above are required for verification). This guarantees the core security of a POS coin.
  • Block signatures are supported and verified (PPCoin protocol requires each block has to be signed by owner of coinstake to prevent replaying attacks)
  • Various security aspects handled due to being POS coin:
     
  • Attacks caused by flooding side chains with invalid POS blocks (blocks that have correct header difficulty, but don't match coinstake protocol) are rejected on receipt, so the low block header difficulty won't cause attacks (Normal bitcoinj trusts only header difficulty, as expected for a POW only coin. This is not the case for POW+POS coins)
  • Similarly, flooding side chains with unverifiable POS blocks (blocks that have correct header diff, but unable to verify/reject coinstake due to the output being spent&removed on main chain) are prevented due to ignorance of their difficulty. A side chain can overcome the main chain only if its *verifiable* blocks constitute a greater amount of work. Unverifiable blocks count as zero work (Until side chain becomes the main chain, where every block will be verified one by one on reorganization)

Is there any way to add darkcoin functionality to mintcoin eventually? Adding true anonymity would add another perk to this coin.

I just sold all my Darkcoin... One my issues with it is that yes, Darksend when it's finished can just be added to any other coin as an added functionality I believe.

For the main part, Proof-of-Stake and the function of Staking somewhat relinquishes your wallets anonymity onto the blockchain.

Therefore, the addition of effective 'darksend' technology into any PoS coin is much more difficult, certainly in the immediate future. It will be much simpler for developers to include this type of function into non-PoS coins.

In terms of Alt. coins, Mintcoin and Darkcoin are perhaps two of the main and most important coins looking forward, imho.

Mintcoin - a pure PoS 'energy saving' coin that serves as an interest bearing / savings account.

Darkcoin - an energy efficient PoW algorithm and true 'anonymous' transactions, when Darksend is fully implemented.

Paspi: might I suggest not releasing the source code to mintcoin android wallet/mintcoinj immediately. I would suggest giving it a 6 month grace period to give mintcoin a head start, otherwise it will be copied to every other pos coin immediately and give mintcoin no intrinsic value. Thoughts?

Its double edged sword. Do you trust a stranger with your coins without knowing what is inside the code?
I guess, its the idea which needs to be discussed, but i doubt that there will be much pro´s for keeping source code private.

I didn't think about this aspect. I just worry that paspi's work will not benefit mintcoin and this his bounty won't really be worth it as larger volume coins like blackcoin or cinni reap the benefits of his hard work.

To have a grace period, the source code could just be released to the developers and they could approve it... It makes sense to have this stamp of approval and only allow Mintcoin fans to use the android wallet for a while before the source code is released.

The main condition of the Developers bounty, is that the Android wallet be open source. We all have to remember as well, that paspi and Mintcoin are not the only ones working on a PoS Android wallet, Silkcoin for example states they are around 70% complete, but their version is a real battery drain.

As long as paspi can complete Mintcoins Android wallet before the others, it will be paspi and Mintcoin that will always be credited with it's development, this is the important part, along with Mintcoin then being able to be used so much easier for mobile transactions.

Unfortunately, due to the licensing restrictions, mintcoinj would still be considered a derivative work since it was cloned from the bitcoinj library.  Therefore, the person releasing the binaries must also make the source code available or risk a lawsuit.

Mintcoinj would be free software and will keep bitcoinj's license, period.

Though I will not release any source code (including library itself) until android binary is available on Google Play. I don't want to give any other coins a head start.

Yeah guys, let's not screw around and end up having someone get sued over trying to hold onto an exclusive feature (that was built off of a base of free open source code as I understand it) for ourselves.

Actually I'm not in favor of paid-for-development clients Smiley But as far as I could see, your clients are already open source, so bounties for conversion are always ok Smiley

I would be happy to see a second application to use mintcoinj library as well as android wallet, it'll make the library stronger and will cause bugs to be found & fixed.

You should note that mintcoinj is not as lightweight as POW-only coins' Simple Payment Verification libraries. For POS security to be trustable, entire blockchain needs to be downloaded (but it will be much lighter than official client for sure, regarding both storage and CPU, but not bandwidth. Also hopefully android app will use some tricks and users won't have to download entire blockchain (bandwidth wise), but a pre-processed blockchain database file instead. You would have to embed similar measures for users to be happy)

Thanks for clarifying. I'm not worried about other coins copying this because

a) everyone would know where they got it from

b) a coin copying this that offers only 1% interest for example is low to the point where it is just a curiosity, not a selling point

I don't have an android phone, but this really adds important value and I can't wait to see Mintcoin get some of the attention it deserves!

I ported bitcoin-seeder to Mintcoin. It helps clients to bootstrap over DNS. Mintcoin didn't have any, and was exclusively using IRC to get an initial list of IPs. With DNS seeding, I hope establishing the initial connection to the network would be easier for new users. It will also benefit android wallet.

I set up a public dns seeder, but a second one will be appreciated. Source is available at https://github.com/keremhd/mintcoin-seeder


(Bitcoinj doesn't have IRC support, and I'm not thinking of adding an IRC library into mintcoinj. Mintcoin-qt will be fine even if DNS seed is down, it can fallback to IRC -- but android wallet can not)
