You can safely launch it together with mainline SpreadCoin wallet, it works like a different coin. Default datadir for this modified coin is spreadtestcoin.

Testing
Wait for cennecting to peers and synchronization and then start mining with one thread using built-in miner. Initial difficulty is 1/1000 that of SpreadCoin so you can take part in this instamine. Don't start mining before synchronizing with the network.

To start a masternode send yourself at least 100 SPR and wait for 50 confirmations, then go to masternodes page and start your masternode. If you don't have anough coins then post your address in this thread and I will send you some coins.

SpreadCoin Masternodes
All the numbers in this post describe testnet, they can change when we will introduce masternodes to mainnet.

The following terms are used in this text:
Node - any full (i.e. SpreadCoin-Qt or spreadcoind), not lightweight (like the one running on Android) node.
Masternode - node which has some locked money amount and performs some additional actions (provides additional services).

Is SpreadCoin implementation based on DarkCoin?
No, this is original implementation.

How is it different from DarkCoin?
In SpreadCoin there are no centralized reference nodes to decide which masternodes should receive payments, it is decided by the network in decentralized maner. In DarkCoin the messages which select masternodes are separate from the blockchain and are distributed independently. This way it is possible that nodes will have different opinion on what masternode should receive next payment. In SpreadCoin all votes for masternodes will be stored in blocks and the payee will be uniquely determined from the previous blocks. Just like you can check that any transaction included in the block is correct by comparing its inputs with outputs in previous blocks you will be able to check that masternode payment is correct by checking previous blocks. Why bitcoin is so reliable? Because all nodes have exactly the same rules how to determine which blockchains are correct and which one is better (required more work) than others, these rules are only depended on blocks themselves, not on the order in which they were received them nor on any other messages which you may or may not receive in time. The network can be unstable in the case of some major event which will break connectivity between nodes but once connectivity between nodes is reestablished all nodes will stick to the same blockchain. The same will apply to SpreadCoin.

How masternodes are elected?
Each node monitor the network and assign scores to each masternode. This scores depend on how well masternodes provide their services, for instant transactions this will be time delay between transaction and its confimation by masternode. Since there may be no transactions and only elected masternodes will confirm transactions there is an empty service - each masternode will broadcast messages signining certain blocks to prove that it is running. Miners will include votes in their blocks. Votes can either be positive (elect not yet elected masternode) or negative (deelect already elected masternode). If masternode has more than 30 positive votes in the last 60 blocks then it is added to the list of elected masternodes. If masternode has more then 30 negative votes in the last 60 blocks then it is removed from the list of elected masternodes. Note that it is possible to determine which masternodes were elected at each particular block.

Can miners cheat to elect their own masternodes?
The system is designed in such a way that all miners will make almost the same votes. Thus, unless you control more than 50% of the hashrate you couldn't actually affect the voting process because you will be outvoted by the rest of the network.

Wouldn't storing votes in blockchain make it too large?
No, there is a limit of 10 votes per block and most blocks will have less votes.

How will masternodes receive payments?
In each block part of the reward (30%) will go to masternode instead of the miner. Elected masternodes are sorted according to their identifiers and receive payments in order, there is no randomness in this process. Since it is possible to uniquely determine which masternodes are elected solely from the blockchain it is also possible to uniquely determine which masternode should receive the payment, nodes cannot disagree on this.

How much SPR is required to run a masternode?
There is a limit of 1000 masternodes, only masternodes with top 1000 amounts will be elected to receive payments, therefore the exact amount you will need to lock will be determined by the market. This amount is locked but it is still yours, when you don't want to run your masternode anymore you can spend it.

Is static IP required to run a masternode?
It is not required and for instant transactions this is not necessary.

What is instant transaction?
It is a transaction which is confirmed by masternodes within seconds after broadcasting. Once confirmed there is guarantee that this transaction (and not any conflicting one) will be included in the blockchain.

What is the state of instant transactions implementation in SpreadCoin?
Most effort was put into developing masternode election/payments mechanism, instant transactions are currenrly not fully implemented. Although masternodes confirm them there is no logic in place to replace unconfirmed transactions with the confirmed ones in the case of double spending attacks and to reject blocks with conflicting transactions. Note that rejecting blocks based on whether or not it includes transactions which conflict with confirmed instant transactions can lead to forks but this can be solved.

Which transactions can be made instantly?
Currently these are all transactions with less than 15 inputs and fee of at least 0.001 SPR per input.

Sounds promising! I wasn't expecting IX to be along in any shape at all yet. :)

Installed but I'm not connecting to any peers yet.  Anyone else?

I have onetwo connection

Can I have more than one masternode if I have two computers with unique installs?

One of my computers is synced and mining successfully.  Will start a masternode once my coins mature.

You can have several masternodes on one computer

Do you see my masternode with address mhkGXCb2GU4apUGvjKKxBPevAZ2HWKRCeD and amount 15000 in the list of masternodes?

Got my second computer to sync after closing my mainnet spreadcoin wallet and restarting my testnet wallet.  Not sure if part one of this matters.

Yes.

Yes, it's in there....

Will you send 100 SPR to mgNJUWE2NwcyB1ewHaSP9yueABwmJM9Rx9 and a larger amount to mzb6NQQzg58zwNvG3i4kQSNmVLs821JAT7

To launch your own masternode you will need to send to yourself at least 100 SPR. If you don't have that much publish your address and I will send to you.

I sent 200.1 to myself and this happened.  Just making sure it is correct that I sent 0.00 to myself:

https://i.imgur.com/APVhlyy.gif

How to start? It appears itself with 500spr.

need 100 SPR for testnet mmux8A6n2988bev37bHhQc69t9M9bp6WTo   

Do you guys see my masternode with 200.1 in your list?

Looks like our first masternode was just elected.

Similar here... 0 amount...

I'm not seeing my 200.1 on my other computer and I'm not seeing my 100.1 on the other one.  How do I start the masternodes so they propagate to the network?  I checked the, "control"

Due to the very fast block generation speed this all maybe unstable for some time.

Ah... there is shows... takes a minute...

masternode coins please ...

I see 4 mns: 15000, 10000, 6666., 500 (my own). I don't see neither 200 nor 100.

upd. see both of them now  :)

On mainnet what sort of behavior would you expect?

And do you have to check the "control" box?  What happens if we uncheck it once it is checked?

I see the 200 and 100 in addition to my 240...

Not mine masternodes that I see:

Do MN with higher coin deposit get any advantages?

Compiled on xubuntu 14.04 fine, mining now, looking good so far:

Nice!  Here is what I see:

https://i.imgur.com/D8h8Ym3.gif

Once 1000 MN are reached, it becomes competitive.  Lowest MN gets kicked off.  So the more SPR you have, the less likely you get booted.

Trying to add 10 SPR to my 200.1 address by sending to that address again.  We'll see what happens!

How about payout?

Mr Spread, we might not see 1000 MNs on testnet - is it worth lowering that number to test the MN bidding behaviour?

No.  Unless Mr. Spread says otherwise of course but I think it would be a BAD idea.

Please send me some SPR - mtypiiHwgaoNFvejc2bwYVh4WK9cr61bsD

Agreed.

If your masternode is selected, you will receive 30% of the block reward.

Mr. Spread.  On the transaction screen it says, "XX confirmations, 0 masternode confirmations"

What is a masternode confirmation?

Payments will start when there will be at least 300 masternodes, otherwise once first masternode is elected it will receive payments every block.
These numbers are probably too big for testnet.

This is for instant transactions.

Definitely too big :)


Cool!

Wallet just synced. Any test coins? Thanks!!

Win7 x64, crashed on exit.
Mr. Spread, is it need to wait some time after restart to became a capable masternode (and take place in payout queue)? If yes, what time and how quickly you'll be kicked of after daemon stopped?

3 connections, how many connections do you have?

I sent an additional 10 SPR to an existing masternode address.  After 50 confirmations (65 now) it did not add to the total.

How do you add to the total Mr. Spread?

7 on one computer, 26 on the other.  Hahah

I have 21 connections

I need 100 for MasterNode: mqRmtQuxCbafe1XPf2uT3iUUbvYSs5PzxF

I also noted this crash at exit, will look into it.
With normal block generation speed it takes one hour to deelect masternode.

Apparently I have (3) masternodes - I don't know how i did it so some explanation is appreciated.  my address is mtypiiHwgaoNFvejc2bwYVh4WK9cr61bsD - can you all see it?

This looks really interesting but I'm kind of a Noob when it comes to building my own shit on my computer lol So I just download the 2 things from the OP for this thread and it should guide me well enough to set up the masternode then?

You will need to stop your masternode (to make your money available, while your masternode is running it is locked) and then send to yourself greater amount.

Little tip, when sending coins from a MN wallet, make sure to not send coins that make up your MN.
Instead, click "settings" "options" "display" and tick the "display coin control features (experts only)".

Exit options.

Now click the send tab in your wallet. There should be a coin control features box.
Click "inputs" "list mode" and select coins that do not make up your MN.

On my computer with the 100.1 masternode I have 219 SPR in my balance.  I just tried to send 219 to my other computer and it says I do not have sufficient funds.  If I sent 119 SPR, it went through.  So when you have a masternode, it locks those funds and they can't be sent.  As I was typing this I got the idea to uncheck the "control" box.  When I did that, I was able to send the funds.

So now we'll see if the 100.1 masternode drops off the list since it is no longer funded.

If your masternode is running then corresponding output is locked to prevent accidentally spending it.

to 'start' the masternode - does that mean check the 'control' checkbox?

#crysx

Ok, just did that.  We'll see if it works after 50 confirms.  Thanks.

Looks like it did indeed fall off.  Nice!

Need 100 spread  to testnet  mpeV4Ai71S9YHmfVpv8oGMF9zShJSfrtNp

Thanks.

Is that different to darkcoin? I thought you could use coins from your masternode balance?

Great if you fixed that!

I sent 100 SPR to 3 of my different addresses, 2 of them had no fee and one had a 0.001 fee which is weird.

And if vin was spent, masternode will be deelected instantly? If not, one can exploit and create lots of masternodes using one vin.

Can confirm.  Was not able to send.  It might be nice to have the display be:

Available Balance: 100
Masternode Balance: 200
Total Balance: 300

In my opinion, locked balances like you've done is an improvement upon DRK masternodes.  Having the display like I mention here would be icing on the cake!

It is deelected instantly.

So starting a masternode is as simple as sending myself 100 or more SPR - going to masternode page - clicking on control?  If i create more addresses for receiving is it better than just sending myself multiple amounts or will I just keep creating masternodes?  Please advise - first time masternoder! :-)

can someone send 100cns to my address for testing

mzNghNiH5grnwjHrPi16FG5CcU3y4chLZv

Ok, so i created new address in the same wallet and sent 100.5 to each.
All masternodes are now live on the network. Is that normal?

Is it going to be this easy to set up once we are on mainnet?

Can someone send 1000 SPR to mgNJUWE2NwcyB1ewHaSP9yueABwmJM9Rx9

I want to setup a bunch more masternodes on one computer.

Amazing, isn't it?

You can send to the same or to different addresses, this doesn't matter.

Depending on the size of the network you are presumably going to run out of bandwidth (especially upload bandwidth on a domestic connection) at some point.

What are the security requirements for the MN server?

1) Firewall settings:

2) DDoS Protection:

3) Cold Wallet storage of MN funds:

4) Bandwidth requirements:


Would be sad to lose the MN deposit coins by not adequately protecting :)

Would like to test out multiple addresses please send some spread to each.  Thanks.

Yeh, thats true.

I have something like 60Mb download / 15Mb upload internet connection. Would those speeds help me out?

Need some to test with

How long does it take to receive votes on my existing masternodes?

coins please... this is a Windows 10 test machine 8)

Guys, should I keep mining after creating MN?

BUG

Here is a screen from one of my computers:

https://i.imgur.com/prtQl6N.png

I only setup 1 masternode on this computer (the 211).  The other masternode was automatically created when I sent 119 coins from my other computer that had an active masternode on it.

Mr. Spread, on my other computer, when you sent the 1000 coins, it automatically created a masternode as well.

I also have this problem.

No harm, but don't overdo it, 1 thread is plenty. I'm still at 86 tSPR and waiting for another 20 to confirm. Please nobody bring a crate of 290s online.  :D

Mr. Spread, any idea of the bandwidth requirement per masternode?

This is weird, do you mean that it automatically checked the checkbox?

It did not check the box, no.  But the box was available to be checked.  I would think it would be best only to be available if you send the coins to yourself, not when someone else sends them to you.  Keep it simple.

Then what is wrong? This is how it is supposed to work, if you have output with enough coins then you can start masternode using it.

Ok, it was just confusing.  I thought you had to send the coins to yourself.

Also, if I shutdown my computer, it shuts down the masternodes, right?  They won't get paid? 

Just registered, specially for testing. Please send coins to mp443aY91BJGiDUhNeK8BBXk92pGsxMooC and n1rU9ZFV23yMicoT58iuDBsmMuBU8amRQN

They will be deelected and payments will stop.

 somebody send me 142 cns. automatically selected as MN ,

 i don't need to send it to myself (i have only selected the checkbox).

is ok with that??

Current masternodes doesn't require many bandwidth. If we will introduce darksend or other features requirements may increase.

We see that votes are a bit chaotic, this maybe due to the fact that people are starting/stoping masternodes/mining and because blocks were generated very fast in recent time or due to some bug.

Mr. Spread, I have a few questions:
1. Can I start MN on VPS, but keep coins on my local wallet?
2. When will launch in the mainenet?

My wallet crashed just before MN listing... I sent SPR to myself, waited for confirmations... MN didn't show yet... then wallet crashed, I restarted and there was the MN...

Does this eliminate the possibility of having your masternode protected with cold wallet storage? Has anyone tried that just yet? Of course, I had to be at work when all the cool stuff started happening. 😉

1. Yes, you can use mnsecret command to generate secret required to run masternode (it is only for running the masternode, it doesn't allow to spend its coins).
e.g.: where argument is output (you can copy it from masternodes page)
Then add to your spreadcoin.conf where ... will be your generated secret.
2. At least instant transactions must be finished before that.

Yes, there may be still some bugs.

Cold storage is possible.

Other than that everything seems to work here 8)

Do I understand correctly that the instant transaction is not implemented in testnet?

I'll provide a 500 SPR bounty to someone who writes up a guide for doing that in easy to understand and follow terms.

Mr.Spread what is the current block reward? is it 10 cns/block. i mined a got a block with 6.664185 SPR. is the remaining 3.xxx goes to masternode?


Status: 141 confirmations, broadcast through 4 nodes
Date: 27-Jan-15 23:22
Source: Generated
Credit: 6.664185 SPR
Net amount: +6.664185 SPR
Transaction ID: d78c675c37f0c0b20ae1d7930e82c58d9ce749cd71d230382791e6205d874056

Masternode payments will only start when there are 300 elected masternodes. We may need to lower this number for testnet because we may actually not reach that much.

So, any vin greater than the current minimum is elegible to act as a Masternode, just check the box. Multiple MNs can thus be easily run from one machine, no static IP required, subject to bandwidth limitations.

Personally I would still rent a VPS.

My initial impression is that Spread Masternodes are a HUGE improvement in terms of ease of setup and administration vs. Darkcoin Masternodes. Which is great, until a bunch of Windows users get hacked and lose their Spread. And the service levels of a constantly fluctuating MN network (more so than Darkcoin as home users join/leave) remain to be seen. I don't see there being too many issues with this, but we'll have to see how well the network performance scales.

We'll need to make cold storage easily doable for people.

It's still very early, but I'm pretty damn excited at present.

Can someone send me some more tSPR? If just a dozen of us can get 10-20 MNs going each we could hit the magic 300 number and see if payments work. Right, I'm off to the basement to fire up a few more boxes.  ;D

1.  presently i have 2 address both on the same wallet as MNS (both are showing as mns in the masternodes tab)

mzNghNiH5grnwjHrPi16FG5CcU3y4chLZv  -142 coins

and

myZTd2WoZG4utRV5JpCanA79gEjaLmiqNT - 101 coins


BUT only one is getting votes. other (myZTd2WoZG4utRV5JpCanA79gEjaLmiqNT ) has zero votes for very long time,

is it a bug or ONLY ONE ADDRESS/WALLET IS ALLOWED AS MN?


2.  what is the purpose of update button in the masternode tab. is it for restarting masternode or
restarting MN is done by restarting the wallet itself?


Edit: Second one also gets vote now!!!!!

Test SPR?  ;D
I believe it means
1) get to know the tx' id with which your mn was started
2) in your local wallet do "mnsecret <this_tx_id>:0", you'll get a "secret"
3) on your vps add mnstart=<secret> to .conf and run daemon

Edit: Second one also gets vote now!!!!!

Are you able to see the IP address of the  masternodes online? I've always disliked that. If these can be set up on a local server(PC) with adequate protection, cold storage and no broadcasting of IP addresses; that = win in my book.😄

Compiling ubuntu daemon now.. Then try the cold setup.

Block generation has slowed down to its normal value, it will now take around one hour to elect new masternode.

Please someone send a few testSPR my way: myGBPs7t9PmmMnuvXz7d3MS5zyTQG69fGE

thanks.

And my (johnny come-lately) AXE!

I want to sent SPR from my wallet to wallet[testnet] and when i click send the adress appear with red and don't send anything need help

Are you trying to send from your usual SPR wallet? It will not work, these are different coins.

Are you trying to destroy your coins?

SPR and testSPR are two different coins.

Yes from my usual wallet can someone send me to muosu7VFVAsbFYLLKnorTULRVQTSVkrWdW or when i can get this coins

Thx in advance

testSPR please for 2 computers:

It is necessary to get 50 confirmations before starting a masternode.

Started (5) more masternodes - please send coins.

Well, 'masternode list' in the QT console doesn't work, but you can see IPs in the debug.log. Someone should try over a VPN.

Coins received! Thanks a lot!

Also CPU mining testnet blocks with 12 cores at same time of main wallet with 4 GPU's, this is awesome, total system stress test  ;D
