I edited my previous post to be more clear.



As I currently understand Evan's plan:



Network pays pool 100% of reward - pool must split reward 80/20 - 80% to miners, 20% to masternode



Are you are saying a dishonest pool can't break this system? Or I am misunderstanding what Evan proposed.



Quote from: eduffield on May 28, 2014, 01:11:37 AM There were originally two strategies for masternode payments. One requires a hardfork and one doesn't. I originally decided to do the one that does, because you can't cheat as a pool operator. But, that comes with a price. The code must reject cheating blocks and that's what caused the forking issue.



The other way is to setup the client to pay nodes in a provably fair way. If the pool doesn't pay the correct amount to the correct node, we'll know and we'll shame them. We'll get miners to move to honest pools.



Like others have suggested, all of the groundwork has been laid. I have implemented the masternodes, the election system for payments and it's compatible with this soft fork.



So why 20% fees for masternode payments? This essentially will create twice as many nodes and create a much higher cost to spy on the network. It also creates a larger feedback loop for the price (because as darkcoin is taken out of the supply, it drives the price up), which is good for all of the investors and security of DarkSend. Miners will get less coin, but it's been proven time and time again that when you decrease the coins generated the price will just go up to meet the cost of mining.



My goal with Darkcoin has always been to take the #2 spot from Litecoin. I believe we have the best chance we've ever had now and these changes will actually help realize that goal.



As for my communication? Lately I've just had my nose to the grindstone, coding all of the time. I intend to be much more involved with the community in the future. This will include getting a team of software developers and managing the vision of the project. I think my time might be better spent in the future doing interviews, speaking at conferences and being Darkcoin's figurehead.



With a non hard fork for the time being yes it would be possible for a pool to cheat.

Ok. Well my understanding is correct then. Not the biggest fan of this solution and its compromise... let's hope that this is just temporary as his most resent post suggests. Ok.

Avoid multiple tickets for masternodes. It will reduce number of nodes making the system less resilient.

No! Forcing people to manage over 2 dozen separate boxes only generates orders of magnitude more opportunities for human error. Too much of a good thing. I'd rather have one node hardened as hell becasue it's holding a million in DRK. Watch to see how often a node gets elected to know how much is in it.. Only adds that much more incentive to make sure people are securing the nodes and thus securing the network. We've already got somebody who was sloppy enough to get robbed... Maybe they'll start taking it more seriously when they can put 50,000 drk in one node, eh?

Maintenance-wise it's a no brainer. 1 beats 50 every day. But for network centralization and resilience, no. You can't have both. It's binary. Either one or the other. And 50 is always more decentralized than 1.



Think of the DDOS vector: If someone wanted to take all the payments to their nodes, they'd only have to DDOS a very few number of multi-ticket masternodes. And fuck the payments, if they wanted to map transactions, they'd only have to bring down the honest nodes and keep online the bad actors. Their job is far easier in this way.

Or go in the irc room and people will help you there to, its not hard.

Sleepyx and others happy to help people who want to set one up for free. Good if you know linux. Else, I do it for you for 10 Drks.



If anyone wants me to setup a Masternode for them, PM me.



If you want more than 3 MNs, it will be 8 drks each. More than 10, I'll do for 5 Drks each. More than 25, we should do a deal.



If you're worried about security, you keep your own wallet encryption passphrase secret. I never need to know it.



You then change your server password. And I'll show you how to lock down your server.



We will NEVER EVER install a keylogger or any malware on your fresh Ubuntu server. We make an honest living. You can do checks after the install, to ensure no malware.



If you're truly paranoid, contact DyslexicZombei and he may be able to do further hardening steps (note: we do not warrant their work). MN count increased to 375 from 371 yesterday.



Why setup a Masternode you ask?



Now, with the new 20% of block reward payment to MNs (starting from June 14th), below are the new estimated ROIs, (Masternode count on left and ROI on right):



374 = 56% p.a. (current Masternode count)

500 = 42% p.a.

750 = 28% p.a.

1000 = 21% p.a.

1500 = 14% p.a.

2000 = 10.5% p.a.



This is based on the price in Darks (or the USD/BTC at the time you buy the Darks to setup the Masternodes and assumes the price in USD/BTC does not change). You need 1000 Darks per Masternode.



Therefore, in time the system could level out to between 2000 and 4000 MNs for a 5 to 10% annual return. However, this implies 2 to 4 Million darks, which is 50 to 93% of current coin supply. This also implies the price of Darks are likely to rise, if people kept trying to setup MNs.



So get your MN setup and get regular income starting June 14! This is a solid opportunity in my view. I've setup 5 MNs already.

But we're not talking about consolidating holders. You and I will not pool our DRK and make a node. You'll run yours how you see fit and I'll run mine as I see fit. If my 50,000DRK node gets DDoSed, then that's 50 entries you don't have to contend with for an hour or so. Do I care when I'm getting 50 entries while I'm NOT getting DDoSed? My bigass node is just one node. The network will be glad to see me disappear for a while. ;-)



As with government scrutiny in other places, I love being the big shiny target they can't really hit. It lets all the other people scurry around unnoticed... If I'm pulling odds on 50 entries a block, and get DDoSed for an hour or so, I don't care, and that means everyone else can relax, while also getting better odds...



If there are like 10 multi-ticket nodes of 20k dark each instead of 200x1k, it's not that you'll go down and I'll stay up to take the profit. We'll both be eliminated. The less nodes we are, the less force they require to take us all down.

thank you very much for the help over skype, it seems that the hacker could enter my vps, don't know how exactly but he did

he will post on darkcointalk some advice and tips to not have the same issue as me



if someone can help me in any way please send some tip on my darkcoin wallet

So here was the issue(s).



It appears there is someone that is pulling all the masternodes from the wallet and running scripts on them to hack in.



And in this case they was able to gain access via SSH, so it had nothing to do with problems in the wallet/daemon/masternode itself.



The firewall was not running, so all ports were open

Root access via SSH was allowed

OpenSSL v1.0.1f was installed on the server

The password to unlock the wallet was still in bash history command

The root password was less than 8 characters

My recommendations:

DO NOT allow root ssh access

Only open port 9999 in your firewall to the world

Only open port 22 (SSH) to a trusted ip

Setup SSH to use certificates for logging in

Do not run any application on the server that you dont have to

Encrypt you wallet

Clear your bash history

There are more, but this would have secured this server.



If any of you can spare a few darkcoins to help this person, he lost 999DRK because of the above issues.



his wallet address is XhGwaKJPMdqEyMU85QBReNNMzVGKDW2EPz



He learned the HARDWAY how not to setup your masternode. I will be putting together a list of things to check and an ISO and AMI for people to use with MOST of the issue addressed, you will still be responsible for checking any think I missed and verify it works for your setup.



His lose WILL help everyone else by showing what you MUST setup so please help him where you can. I will pull some together myself to send.
