Thanks, all working now!

You need to remove data directory in step 2 as per procedure. I have updated my previous post and changed this to bold

@eagleflies
Looks similar to this:

The previous test wallets worked fine, but with this one I'm getting the following error when trying to open it:

MinGW Runtime Assertion
Assertion failed!
File: src/kernel.cpp, Line 475
Expression: pindex ->pprev||pindex->GetBlockHash()==(!fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet)

Thank you for feedback. It should work now.

Feel free to give me your receiving address and I will send you some play money. Also if you own some Noblecoins now you will be able to access them on test network too.

Many thanks for the update, Eagleflies. I'm keen to get testing but unfortunately the link to the new Windows wallet doesn't work for me. Can you check the link please.

Edit: Link works now, many thanks.

Tentative date of switch to PoS: 2015-03-02 - moving the date few days later since we need some time to perform current round of tests


New test PoS wallet - version 2015-02-18



Procedure how to join tests:
1. If you participate in tests please stop test wallet.
2. Remove data directory (windows: C:\Users\username\Appdata\Roaming\NoblecoinPOS), (linux: you can delete everything except noblecoin.conf from ~/.noblecoinPOS)
3. Download and run new version.

Windows -> http://104.236.195.137/noblecoin-20150218.zip  md5sum: 03baa2c39cb64603da7e3e21897c3596
Linux -> https://github.com/eagleflies/noblecoin/

Test block explorer -> https://chainz.cryptoid.info/nobles/
Documentation -> https://github.com/eagleflies/noblecoin/wiki

Changes:
- increasing fee to 1 NOBLE per transaction. Current fee of 0.01 is less than 1 Satoshi so does not make much sense.
- lowering max time drift to 1 minute.

Brief explanation:
- Our previous test wallet used default value (2 hours) for max time drift. This poses a security issue as attacker can stake blocks almost 2 hours into the future. When this happens difficulty drops steeply since client thinks it has to quickly decrease it in order to make staking easier for whole network. This makes it easier for attacker to double spend.
- I was able to stake few blocks about 2 hours into the future on our test network which caused difficulty to drop from 2.5 -> 0.50 within few blocks.

Long explanation:
- Please read an interview with presstab where he talks about how important time drift is http://bitcoinist.net/interview-presstab-pos-vulnerabilities/

Test plan:
- Start test wallet. I will try to cause problems to network by mining blocks into the future and will see what happens.
- You can try to mine new blocks using proof-of-work. To do it issue command 'setgenerate true 1' in console
- If you own some noblecoins on real network you can try to import them into test network. This way you learn everything which is needed to access coins after the switch. This is the recommended procedure https://github.com/eagleflies/noblecoin/wiki/Importing-private-keys-from-old-wallet.dat-using---salvagewallet-option . Alternatively you can send all your money to an exchange and they will take care of this for you. The important thing is to transfer money before the switch if you want to do this via exchange.
- You can try staking coins using proof-of-stake. If you already own some noblecoins you can get access to them using methods described above. Or give me your test address and I will send you some play money.
- The coins on the test blockchain will be distributed in about 10 hours.

so have you taken over this coin or are you done when pos is done?

Please read last few pages of this thread and everything is there.

Myself I'm a dev who is helping with PoS migration.

Mind you. This is still test wallet.

what do you mean people are not answering you or deleting your posts?



that is still right where you left it along with the person answering you to the best of their ability, ROFO is working on the market place for noble and developing NOXT's backbone right now

Hello from Greece I do mine NOBL long time now and I just downloaded the new wallet!! Success!!

Can we get some answers here or just ignore the fact that Rofo is not helping? Eagleflies are u in charge now? are u running this coin?   What happened with ROFO?  Is he only committed too Noblenxt now? Why wont either of you comment on this??? Why are my posts being removed?

These are the first ever coin I invested in and I am going to hold my coin as long term investment. Nobl is very stable and long lasted coin since last year.

Nice one 

8% and 2 hours.

There will be mining during first month or so. We will have both PoW + PoS at the beginning after transition.

I think we settled for 8%

What is the % interest on stake, and what is the minimum stake age plz?
