Wallet update to v1.5

Fork at block 1086321. PoW will be disabled. Reason, chain is getting stuck too often.

Download wallet here: https://github.com/Nevacoin/nevacoin/releases/tag/v1.5.0

Exchanges notified.
Block explorer already updated.
Electrum servers updated, The Android wallet is safe to use: https://play.google.com/store/apps/details?id=com.cryptowallet.si


Hashrate will be rented in the coming days to start pushing the chain forward. For now some time will be given for most people to update.

If you miss the update you will have to resync from scratch.

Only 3300 votes to go to get NEVA listed on Tokens.net Exchange

Neva got listed on Novaexchange! Smiley

https://novaexchange.com/

NEVA/BTC and NEVA/DOGE pairs.

Lets make 1000$ volume so I can add it to coinmarketcap Cheesy

Hello all, project is not dead.

You can all consider @staysecure as the community manager for Nevacoin, he has much more energy for managing communications than I do Smiley

We are working on the coins together (Neva, Lana, Taj and ARCO), we live in the same city and have meetings on a weekly basis and are in the process of hiring a good programmer to take the coins to the next level.

Neva also says hi Smiley

Wake up Krile. Block chain is again stacked. What are you going to do about it?
I do not understand why you can not find some permanent solution?

Right now, at what stage is your project?

The current plan is to make a swap.

Starting a new chain on a newer codebase, same pow algo same reward structure.

The plan is to make a snapshot of the current chain at a certain block height, and put those balances into the genesis block of the new chain.

Some of the changes:
1. longer block time (at least 5 minutes, if not more)
2. better difficulty target algorithm
3. PoW forever, coin will remain pos/pow hybrid
3. maybe annon features, not sure about this yet.


Why do this:
1. start fresh, leave old bugs behind
2. longer block time, less blocks, faster sync, less confilcts and spontaneus "mini" forks in the network
3. go to current bitcoin codebase, segwit and all the fancy stuff

Everything will be announced with enough time in advance. Right now I am still looking for a co-developer to help out with the deployment of this idea.

The ideal timing would be march 2018 for the two year anniversary of Nevacoin, but hard to say if everything will be tested enough by then.

Do you like the idea? Feedback welcome Smiley


Krile, i like your ideas.
But what will be coin cap, how many will be created once when you make it POW forever?
Second i would suggest to lower number of POS blocks, something like 25% compared with 50% now.
Better target algorithm is a must!


The coin cap will be the same as now, 26 milion with halving. The halving will be extended if the block time will be raised. So from the current 7 years to maybe 10 years. Or maybe I will reconfigure the schedule so it stays at 7 years. Not sure about that part yet.

All the coin monetary parameters will stay the same, except the block time and tartgeting and other technical stuff. I wil consider this suggestion about reducing the number of pos blocks, if that is even plausible.

I'm stuck at block 490688 Sad
tried to clear my peers and add only peers with latest block - no result Sad

Just delete everything, keep only wallet.dat. It would be nice if you have some wallet backup before block 490688. Then start with neva.exe in root of c drive. It must work, happened to me before....


Like he said, delete the whole dir except wallet.dat and resync.

Here you go folks. New Git org and repo. https://github.com/OC-CryptoCurrency/OC

Great job on convincing me to do this  Grin

Once the explorer gets updated we can retry adding this to coinmarketcap

OCminer will be happy to see this Wink

Bought some power on nicehash, the chain moved along now Smiley

Can you please share here or on PM what was the pool you have used via nice hash?

Thanks.

Hey, this is the pool: stratum.mineblocks.co.uk   port: 4010  userame: wallet_address

Not good at all. Block chain is stacked due to big auto algorithm change pools. What is worse they are mining only in order to dump the coins for profit-BTC.

There must be some kind of protection for this kind of spikes and block chain halts.
Can we implement something like this: if no coin mined in one hour period create dummy-orphaned block and jump to lower difficulty?




I hope its only by accdent and not some kind of attack. The last few days this is really becoming a problem, before it would get stuck for max an hour or so.

Worst case I will make a snapshot of the chain and start a new one on a newer codebase (eg bticoin 14.0)

I have never seen a PoW minable coin where the block hashes aren't actually the proof of work (a bunch of zeros in front of the hash)

Why is bata designed this way? Just a general curiosity Smiley

Hi here is an example of a raw block:

{
   "hash": "2959d2161759004644c9bda9ac37507a29b67b7bb3580ba1bcc610c3fa8b11d9",
   "confirmations": 1,
   "size": 241,
   "height": 779555,
   "version": 4,
   "merkleroot": "954945425eb40dbb2fc3d2d6ddc87d92ba268dc341d0fe03e71e76246e8599a1",
   "tx": [
      "954945425eb40dbb2fc3d2d6ddc87d92ba268dc341d0fe03e71e76246e8599a1"
   ],
   "time": 1506434691,
   "nonce": 2002999098,
   "bits": "1c02b746",
   "difficulty": 94.25787966,
   "chainwork": "00000000000000000000000000000000000000000000000000c0c4830ef0bc35",
   "previousblockhash": "48e9cfa2a689877d4985f63df903a6027c1c14c35ed02107473d72fc351b607c"
}

If you are referring to chain work then an explanation is available here:

https://bitcoin.stackexchange.com/questions/26869/what-is-chainwork

"The chainwork value is really just the total amount of work in the chain."

I know about chain work, its the cumulative work on the chain. I was wondering about the block hash, which tells the work on the individual block. Why is it hashed this way in bata.

Example a peercoin pow block:
Code:
{
   "hash": "0000000000000000ee2f9eeca90dd0708459b7e78de9c64d19bc3e73fd2d8e8a",
   "size": 3790,
   "height": 324835,
   "version": 1,
   "merkleroot": "e97bfe5e6c6d4fbf4acb8956ae0228dd6f2047b690b8245e128683ce8688dcb7",
   "time": "2017-09-26 11:24:01 UTC",
   "nonce": 2768994299,
   "bits": "1902e43a",
   "difficulty": 1485349089.4013,
   "mint": 50.94,
   "previousblockhash": "4235e040578bae46616f11daa644fd1cb485db7c6a5948f5e40608785aa4a6b8",
   "nextblockhash": "00000000000000011b4841bb4aead702f2e266ba645b7484c3a239bf67101f3d",
   "flags": "proof-of-work",
   "proofhash": "0000000000000000ee2f9eeca90dd0708459b7e78de9c64d19bc3e73fd2d8e8a",
   "entropybit": 0,
   "modifier": "213b2338aec7bc5a",
   "modifierchecksum": "4ba28af2",
}

The proofhash is the same as the block hash.

Again I am just curious, if there is a special reason for this design decision Smiley

Hello,


We opened a new mining pool with friends : unimining.net with NevaCoin minable on it. Mining fee of 0% until 1/12 then 0.5-1%.

We didn't add NevaCoin because it is profitable to mine but we found its concept kind and human. I've never used NevaCoin as a gift or birthday present but its non-financial concept is interesting. We chosed to sustain and decentralize its network: let's mine NevaCoin with us on unimining.net.

Thanks a lot. Will join your pool Smiley

Looks like the chains stuck....?

Looks like it...seems like a difficulty pump. I turned a few more cards solo to push it forward.

Got it Cheesy

Since aikapool delisted, the majority of pools are now auto switching...will be a pain in the ass Smiley

To be fair, everything is in the red today in crypto land Smiley

Hi all, nevacoin.net will be down for a few hours, I am moving the webserver to a new location.

Cheers

Is it just me or is this kinda dead in the water?

Who is mining this anyway? The chain is barely moving...
