Thanks to all the notary node operators, we found and fixed several crash type bugs.
still hunting down one last crash and I also need to add a height range to the notarized checkpoints, but that is simple logic.
the crash is appearing only after a block is mined, so takes a while to duplicate
I also notice the few things I added to the bitcoind code has slowed things down, it sure isnt iguana speeds... Probably will need to allocate a bit of time to optimize performance
I dont think many people reading this thread realize that every day there are a dozen notary node operators updating to the latest build and helping troubleshoot any issues with the latest versions. Without all this effort there is no way that dPoW would have come together so fast as debugging is a time consuming process.
Having so many different servers testing it all at once... well it is hard for bugs to hide for long. They are all so busy with the servers, they hardly ever post here and are the unsung heroes
I think there is an archive of the #notarynode slack channel somewhere so people can see how much effort is being put into komodo.

is this gpu minable?
It is not designed to be a mined coin so unless you are a notary node, mining wont be profitable. Unless KMD price goes way up, GPU mining wont have any ROI. There are GPU miners for equihash though, so technically it is possible, just not practical Hi, jl, I have some questions, looks interesting, I wanna be a node. 1. What is a notary node? Is it like a masternode in dash or xem? 2. We need to set up a server to be the notary node, right? 3. The specification of notary node rewards and mining rewards? More details? I can't find it in your op. Maybe you can show us some light. Thx. explains notary node. busy tracking down bug now, no time for more details. hopefully the info you need is there |

dPoW status
Fixed several bugs I found in yesterday's code and now it is keeping persistent state pretty well. After the bug fixes I havent seen it forget any state change event, which are all in an append only file.
got the round robin mining code finally compiling, a lot of small changes in the C++ code was required. released a hardfork version for testnet at block 34000, and we will find out tomorrow if the mining diff is lowest diff for one notary node per block, on a rotating basis.
also beefed up the updating of elected notaries via the ratification transaction. this went hand in hand with the mining difficulty change as both needs to know the exact consensus on the elected notaries as of any height. Coding that up allowed solving both issues at the same time.
i also changed from linear searches to hash lookups for both searches that are needed, so now there wont be any slowdowns regardless of how many notary sets there are or notary utxo.
I am sure there are still issues as the notary operators are reporting some problems compiling, but I had a bit of time so I figured I would update status.
What is left to do after stabilizing the current release is: award 5% APR
yes, just one item left and komodod will be done except for mainnetization.
I am making good progress and looking forward to connecting assetchains to dPoW next week.
Just saw: 2016-10-20 17:34:16 ERROR: ContextualCheckBlockHeader: forked chain older than last notarized (height 33420)
This is the dPoW protection in action! The latest notarized height is 33420 and a block earlier than that was trying to propagate, and rejected.
probably some edge cases yet to fix, but always nice when the first deployment is working as it should

Is it ok to run a notary behind a VPN?
Or must the physical server location be spread?
with the right ports open it should work. not sure the performance impact, so it is worth trying |

I came up with a revised way to deal with the round-robin mining which once it compiles I can debug. It will allow an almost as efficient as PoS method for generating blocks, even though PoW is used.
This prevents a mining war between the notary nodes so the planned for economic incentives will not be skewed.

Using that logic, everybody that has a job is raising money every month. I put the NXT assets (other than SuperNET) in the category similar to working at a job. The amount of money raised was comparable to working at a job, so it should be compared to having a job instead of an ICO. So yes, I have worked in crypto for a while and was paid for it. I have never denied this.
But if you want to count my raising thousands of dollars in the same category as multi-million dollar ICO, I guess you can do that if you just ignore the 100x difference and count pennies as dollars.
You sold shares(assets) in something. Thats a bit different than a Job. For sure the amounts where not that high as the Supernet ICO for example but is that making any differenced to the people which bought into that? No it doesnt. NxtVenture for example.. everyone can form his own opinion. http://coinmarketcap.com/assets/nxtventure/#chartsRemind me when the NXTventure ICO was held? You cant because it wasnt. A trading market in NXTventure was created and people traded it in the aftermarket. So people bought and sold it from asset exchange market. The vast majority of the trading volume was done by other people. I did do some occasional trades, but only as a normal investor. this is quite different from an ICO, are you aware of the difference? It was created as a vehicle to distribute other assets and when NXT AE was viable, it was doing fine. It is not my fault NXT dropped 80% in value and also decided to abandon assets in the switch to ARDR. |

I have not denied that I raised funds from NXT assets, however other than SuperNET they were not done as an ICO and the scale is orders of magnitude smaller.
If you raise funds from private investors, that is funds but it is not an ICO.
Maybe that is your confusion? You seem to be considering any funds raised via any means as an ICO. So if I get a bounty for doing some work, is that an ICO? If I get paid for doing coding, is that an ICO? If I invest in an ICO and make money did I do an ICO?
Okay, maybe I made a mistake by equate ICO with raising funds. But isnt that the association most people here have which invest? I think so. So yes, you did 2 ICO's. But you raised money several times in the past. Using that logic, everybody that has a job is raising money every month.

But if you want to count my raising thousands of dollars in the same category as multi-million dollar ICO, I guess you can do that if you just ignore the 100x difference and count pennies as dollars. Lets talk about this ico only. You implied that 10k BTC is more than sufficient for komodo then why not lower the cap to 10k BTC? Investors are not going to get much returns is the ico is over Bloated. 10k from here (under 2k so far) seems likely anyway Then why the cap is not lowered. I would definitely double my investments in komodo if the cap is lowered. Funds have already been raised under the existing terms. Changing anything significant like the cap is not anything I would be comfortable with as while it might make you happy, it will surely create many complaints. In any case the max is just a max and we are not likely to achieve it, so there is likely little difference. you can always wait until the end and if it is still below 10K, then put in more. |

Investors are not going to get much returns is the ico is over Bloated. Well we are still quite far from even the 10K, so why the concern? Beyond 10K BTC will allow for a larger staff, a lot more marketing but most importantly fully funded LP (Liquidity Provider) nodes to provide central exchange level spreads for the native DEX. This is strictly not needed for Komodo, but the DEX will be enabled for all the dPoW assetchain coins so it does relate. If the investors want to fully fund a native DEX ecosystem, they are able to. The Komodo run LP nodes would then be able to earn some margin on the volumes so it would end up generating revenues. Ideally, Komodo funds will be able to earn income and we can pay all the costs from such income. In that case, instead of 10 years of funding, it is fully funded indefinitely. I prefer to let the market decide if what is wanted is the minimal Komodo, or the medium Komodo or the monster Komodo. |

Wow I really feel like James is taking a lot of stick right now.
IMO Komodo is a natural progression and a great addition to the SuperNET project. James is the most active developer I have ever seen. He is constantly updating this thread with development progress and he gets stuck in with all discussions. Which is A LOT more then I can say for most coin devs.
At the end of the day every ICO is going to have its grey areas... the points which might put you off investing but which you must weigh up yourself. I see people investing 10's of thousands of BTC in projects which have no real track record of delivering a working project in the crypto space.
And I get where people are coming from with the ICO caps especially when you consider the BTCD to be added after the ICO, which will dilute KMD shares even more buts these are the parameters of the ICO, it's been clear from the start and if you don't like it dont invest, wait for KMD to hit the exchanges and then hope the price does drop.... its like educated gambling. Either way I believe James has been very open and honest the whole time and it's his attitude alone which has actually given me faith in this project and lead me to invest.
Keep up the hard work mate there's lots of us out here that appreciate what you are doing.
Thank you! I thought finishing a working dPoW ahead of schedule would have some positive impact, but all it seems to have done is bring out the trolls. It is good to hear some positive things for a change. |

Please name all of these ICOs I have supposedly done other than SuperNET and Komodo. Keep in mind Komodo is a part of SuperNET
Whats with your bunch of different NXT Assets? You sold shares of your different "comapnys" or Projects to the nxt community to raise money. How do you call that? Most of the assets are MGW assets or were share drops where they were sent as dividends so did not bring any income. InstantDEX and NXTcoinsco were private placements and the total amount raised from all the NXT asset sales is less than 5 million NXT. Considering the number of hours I have worked, I think it comes in at less than $5/hr. I suppose you consider that being greedy $5/hr? You raise thousands of bitcoin from supernet, why can it be possible for $5/hr?? SuperNET funds for the most part were not spent, it acts as an investments fund. supernet.org/nav.php shows the portfolio. The drop in portfolio value was primarily due to the massive drop in NXT price. In the last year I have almost tripled it from its low via successful investments. The funds spent on operating expenses have not gone to me, but to the other devs, servers, etc. All the people that think that I spent all the SuperNET funds on myself are misinformed. Most of the funds are still there and my goal is to grow it to above and beyond the original ICO value. Komodo is a key part of SuperNET, so even Komodo is part of the original SuperNET plan. All this talk of me abandoning projects is just silly as all I have done for years is work on the various different parts of SuperNET. |

Again I repeat that a lot of those assets are either MGW assets or sharedrops or third party assets.
Do you understand what an MGW asset is?
Yes i understand what a MGW asset is. There are a couple of holding funds assets whose purpose is to hold other crypto. These are funds that are held in the asset and cannot be spent.
The MGW Assets. I know how the concept is working. These Assets where not my point. You say you dont care how much money I raised, but you complain about all the "ICO" I have done. Do you dispute my estimate of 5 million NXT raised from all the NXT assets? If not, then do you have a problem that over two years I generated less than $5/hr? How much do you consider a reasonable amount to have raised?
Yes i dont know how much it was and it doesnt care. Most people dont know because your Assets-Construct is absolutely inscrutable. I dont know how much is a reasonable amount but thats not part of the discussion! The point is that you raised Money(5Mio Nxt as you said) different times in the past (doesnt matter how do you call it) and here you say you didnt. Should everyone get payed for his work? Hell yes! Raise millions if you want in 1000 ICO's. But be honest to the people so everyone can decide for himself if he is willing to take that risk! I have not denied that I raised funds from NXT assets, however other than SuperNET they were not done as an ICO and the scale is orders of magnitude smaller. If you raise funds from private investors, that is funds but it is not an ICO. Maybe that is your confusion? You seem to be considering any funds raised via any means as an ICO.

Okay.. here some more assets you placed. You wrote some Posts in that thread where you didnt protest against that list so its not wrong isnt it. ALL jl777 Asset Listings I dont know how much money you raised and where it is now and i do not care. But dont run around and say that you had only made 2 ICO's. Thats not true! The people in NXT community which throw you their money can confirm that.. Again I repeat that a lot of those assets are either MGW assets or sharedrops or third party assets. Do you understand what an MGW asset is? Do you understand what a sharedrop is? There are a couple of holding funds assets whose purpose is to hold other crypto.

It is stated that anything abive 10k raised is war chest. What exactly is war chest? Will there be a buy wall at exchange just after coin launch? Will james use the ico btc to protect investors from the initial price drop?
Investors have been burnt recently by over bloated ico like waves. No one buys after coin is launched at exchange. Price drops to half the ico and the investors who funded the ico are called fudders when they demand justification for price drops.
Why not reward the investors by capping ico at 10k btc.
Oh and i have done good reading. And i can read what has not been writeen too. I know why the opportunistic timing of this ico with zcash launch right in the middle of your 5 week ICO.
afaik the majority of ICO funds goes to paying notary node fees for 10 years, investors who need price support shouldn't really invest, more risk than they can cope with 10k btc is more than enough to pay notary nodes for 10 yearsand develop the coin. Anything above that is going straight to dev and his teams pocket. I am waiting on sidelines on this one by buying btcd instead of investing btc. If this gets crowded i will sell my btcd and stay away frim james and his never ending icos. After all james is not like vitalik who sticks to his project no matter what. As soon as something more interesting comes james will leave kmd investors in dry and raise another ico. In my opinion a dev who sticks to his project for a long time is more reliable than the one who hops at each money grabbing opportunity. Please name all of these ICOs I have supposedly done other than SuperNET and Komodo. Keep in mind Komodo is a part of SuperNET Maybe you confuse my investing in ICOs with conducting them? |

dPoW branch of komodo now keeps all the dPoW in a persistent state file. It just started working, so havent had a chance to fully validate it, but at least dPoW is all coded now.
I still want to replace the slow searching with a much faster method, but for now the dataset is small enough that there wont be a speed issue.
Last things left to complete are 5% APR and mining round robin.

c) was pretty fast to get done. the following is from the getinfo call:
{
"version" : 1000001,
"protocolversion" : 170002,
"notarized" : 28790,
"notarizedhash" : "03fbc40229c52691c25ad702058835dce616c30b81479124655d3d8c4b456ea3",
"walletversion" : 60000,
"balance" : 0.00000000,
"blocks" : 28794,
"timeoffset" : 0,
"connections" : 19,
"proxy" : "",
"difficulty" : 2.82596557,
"testnet" : false,
"keypoololdest" : 1476816974,
"keypoolsize" : 101,
"paytxfee" : 0.00000000,
"relayfee" : 0.00005000,
"errors" : "This is a pre-release test build - use at your own risk - do not use for mining or merchant applications"
}
As long as you wait for your tx to be at or before the notarized height, then it is as secure as bitcoin transaction as bitcoin blockchain would need to be modified for the notarizedhash to be changed.
Once I get it so it can resume properly, then the core dPoW functionality will be done.

dPoW progress report.
I added the code inside komodod to use the data that the iguana notary dapp is creating.
Currently, it isnt saving the data to HDD, so it is just to make sure that all the data processing is correct. So far, it appears to be updating properly. Not being familiar with the C++ code, I was pleasantly surprised to find a clean checkpoints test that was perfect to expand to add the dPoW checkpoint. So as the notary dapp writes the checkpoint data, komodod processes it and sets the most recent NOTARIZED_HEIGHT and HASH which the checkpoint test uses.
komodod is also detecting all the special transactions and while it isnt updating the active notary list yet, it now has all the data flowing through it.
I had allocated a full week for this part, but it seems I did most of it already. The following is the remaining todo list:
a) update list of current notaries using processed data
b) HDD storage of processed data
c) add "notarized" fields to getinfo command
d) award 5% APR for utxo older than a week when they are spent
e) round robin mining difficulty
a) and b) are all that is needed to get a full dPoW implementation live and it wont need any GUI. with c) it will provide the explorers the info needed to color code the blocks that are notarized. I dont expect these three items to take much more than a day.
Once those are done, we are left with the 5% APR and the round robin mining to achieve nearly PoS efficiencies even though zcash PoW is being used.
The last two require more C++ code changes, so progress will be slower than my C speeds, but I aim to complete it by start of next week. At that point, the komodod changes will be complete and all that would be left is to rebase to the final zcash release. The last rebase only took a few hours, so it seems we are getting close to finishing the komodod changes.
I have allocated next week to adding dPoW into assetchains, so there will be real live example of how to use dPoW from external chains, and it also solves the method of distributing REVS.
Beyond that, I need to revise iguana a bit to properly deal with the latest komodo changes and see if I can get basilisk functionality to work. That would allow all OS to be able to do at least the transparent komodo transactions. I already added a komodo pass through mode into iguana that allows commands to be sent from GUI to komodod.
So, as the ICO is in progress, the core tech is being completed. For the additional development work, of course, the ICO funding will be needed so it cant be started until after the ICO.
