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 Smiley

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 great news paspi, I'm really glad you've been working so hard on this.

A shout out to the rest of the community to request donation pledges for this "Bloom Filter" feature, as well as one of you other programmers to step up and start working on this. I'm sure paspi will be able to help you along with it if needed.

Should you want to pledge a donation, please PM me the amount, and I shall add it to the list and post it.

Mintcoin: Get some
Ok so, I am having nothing but issues with this new wallet. Every time I turn around it stops syncing, I have to close and reopen. Then the coins I have minted will be lost. Is there a node I need or something I am doing wrong? I am really getting tired of loosing coins.

Her is my .conf

Have you tried to repair the wallet yet?

Type in the debug console repairwallet if that does not work use salvagewallet

Error: blkindex.dat appears when I try to open new download wallet. I also downloaded 1.7 to try that wallet, but it won't sync- any help would be appreciate as I am new to all this forum stuff.


Your blkindex.dat is probably from 1.6 or earlier. Since 1.7 is a hardfork, you need to delete all in config dir EXCEPT your wallet.dat and .conf file if you have one. Then start 1.7 or 1.8 client, it will sync from the beginning and you should be fine.

You must have used the old (1.6 or less) client to sync and passed the switch point (220000), otherwise 1.7/1.8 client will sync directly without any problem.

Which client type are you trying to run?  Mac, Windows, Linux?

depends which version did you use earlier?

I had 1.5 then jumped to 1.8. Should I update to 1.7 then back to 1.8?

Since 1.5 was before hard fork. Im afraid that all coins you minted after block nr 220 000 are in wrong fork and lost forever.


*drops to knees and screa,s* "Wwwwwwwwwwwwwwwwwhhhhhhhhhyyyyyyyyyyyyy god?"

Makes since I am bummed but such is life. After all, its magic money anyway.

As Papsi said you didnt loose more than a bit of cpu time
Your coinage is ok in the right fork, dont worry, get up and dry those tears!!! jejejejeje

Are you still talking about coins that you got on the other old fork version (pre block 220,000)?

Hello,
If you're using 1.8 wallet, you can safely ignore sync problems. Just hover your mouse on the "syncing" text, if it says last generated block is generated just a few seconds/minutes ago, then you're fine.


There are some rogue clients on the network that announce wrong block heights (they are people who did not upgrade to 1.7 or upgraded late, and still haven't noticed), when such a client connects to you, it confuses your client. Your client disconnects them, but the estimate on UI stays there. So it's really a display issue.

First let me say i am not a tech person at all. However the steps below worked for me.

I checked the .conf file in the new wallet and it contains different nodes from those listed elsewhere on the thread.


If you are updating now you will have to do a clean install. That means backup your wallet.dat to a safe location, and delete everything mintcoin. When you get the new wallet, place your back up in the appdata folder and launch.

There is a .conf file in the new wallet, don't use unofficial sources for your wallet : http://mintcoin.cc/download-wallet/

Edit: To find your appdata folder- Click Windows button on left bottom of screen and put this in search box: %APPDATA%/MintCoin

Notes- You will find Mintcoin files in your download folder and your appdata folder. If you delete everything EXCEPT wallet.dat you will be able to do a clean install.

-Future versions shouldn't require these extra steps. This is a result of going from hybrid PoW\PoS to pure PoS

NEW WALLET HAS COIN CONTROL!

In wallet choose settings-->options-->display-->mark "display coin control features"

Click OK. You will see CCF on Send tab now.

If you want to send only the newest coins do the following:

1. Open "inputs"
2. Choose list mode
3. Click on conformations twice to sort by lowest amount of conformations first.
4. Select enough adresses to fulfill your required amount.
5. Click OK
6. Use sending tab as usual.


Ill give it a go and make short video about this feature soon.


Thanks Kergecoin!

If you would like, thank Kergecoin with Mint-  MrXW1RKLDe8VMNwTwLwSiKuATN5M74EL85

Hashcow is the more rentable http://poolpicker.eu/
But as you says a preffer doing my diligence alone, i preffer receiving my BTC first and then rebuy at a price i want.

Yeah i was couting on 0.005 actually. Or aiming for it/woulda been happy with it.




(so... 0.0013 in 14 hours give about :



So yeah.. will definately keep looking for it. But like i said.. I can get more just mining doge and trading that for mint myself atm.. Sad
