Re fees, remember that "coin age" is part of the fee calculations too, so if one time that you send an amount you had old coins adding up to that amount you will get one fee but then if next time you try to send the same amount and the only coins you have left to use are new ones (such as when you only had about enough and the only reason you have it again to send it again is the other person testing with you sent it back to you) the fee could well be higher because part of the anti=spam concept is to discourage sending the same coins back and forth back and forth back and forth like you might be doing in your testing if you didn't have much in the wallet that you are testing with in the first place.

That is part of why I tried to suggest lookign what the fee would be using one version of the client - an old one already in use for a long long time - then look what the new client would say the fee would be for the same amount sent using the same wallet. In other words don't actually send the coins since that would change the contents of the wallet. Just look what the client says the fee would be, then try the other client to see what it says the fee would be.

Once you actualyl send the wallet changes, and if you send most of what you have then the other tester sends it back it has become new coins, each send consumes "coin age", the newer the coins you want to send the more it looks like you are spamming the blockchain by sending back and forth or around in circles, which, taken to extremes, is one method of spamming blockchains thus one thing the anti spam stuff is trying to discourage aka make expensive.

However if I understand the posts-so-far correctly I get the impression the problem has actually been that one of the testers was not downloading what they thought they were downloading due to some"placeholder" concept confusing which files are which versions for what platforms.

...

Re the volatility not knowing how much a share is does increase the unpredictability. It does not really seem all that hard to figure out that a devcoin is worth usually somewhere between 30 and 230 satoshis, nor that is as been more usual lately to be between 30 and 130 than between 130 and 230. SO I think a lot of that side of the uinpredictability is easily solved by not placing "market orders" but instead simply placing a sell offer at a a price of your choosing, such as at the price your budget or business plan assmed.

e.g. If your business plan calls for being able to get 100 satoshis of bitcoin per devcoin, place your order at that price. It might take a while, but there does not seem to really be much doubt that one can get that much per devcoin even though we did go through a longer dry spell than hoped/expected lately between one time offers to sell at 100 were gobbled up and the previous period in which such offers were gobbled up.

It is a queue, really. Everyone who wants to dump their devcoins is in a first in first out queue at any particular price. The delay in getting your offers to sell at 100 accepted by a buyer is partly due to all the people who placed their offer to sell at that price before you did. Then also by all the people who got impatient and decided to place their offer at 99 so it would get acted upon before all of the offers to sell at 100. Then some folk get even more impatient and decide they won't wait for 99, they will wait for 98 which will come sooner, so a queue starts to build up at 98. And so on.

I have orders placed way up over 300, I only recall seeing such orders gobbled up once but I plan to have it happen again so I have offers up there so as to be first in line to sell at those prices when the time does come that they start being acted upon.

So GetMinFee does the following:

Code:

int64 nMinFee = (1 + (int64)nBytes / 1000) * nBaseFee;

and then allowfree which resets nMinFee back to 0 if its a small transaction (I commented this out for now)

and then   

Code:

 // DEVCOIN: To limit dust spam, require an additional one tenth of CTransaction::nMinTxFee/CTransaction::nMinRelayTxFee for each output
    BOOST_FOREACH(const CTxOut& txout, vout)
         nMinFee += nBaseFee / 10;

Which adds  a small dust fee protection. SO there can never be any free transactions.

For my tests regardless if I try to send myself 1 coin or 50k coins I get the same transaction size of about 225-227 bytes... thus my fee is always a little over 1 coin since basefee is 1 coin. However the above minfee calculation truncates values so that minfee will jump to 2 coins once nBytes is > 1000 and less than 1499 (the normal c++ round would round up at 1500). So you get jumps... however if we do:

Code:

int64 nMinFee = roundint64((1.0 + (double)nBytes / 1000.0) * nBaseFee);

then we get a smooth fee increase as bytes increase. so for 225 bytes this now prints out 1.427 dvc fee as opposed to 1.2 dvc fee for the code that truncates. If nBytes fluctuates quite often then we might want to use the one I changed it to, the double casting and roundint64...

Wekkel, since your transaction was 2k the fee would jump so this confused me still as I don't know how its getting 6 dvc from nBytes of 2000 and nBaseFee of 5 coins.

Anyways now as nBaseFee is 1 coin and nBytes is 2000 then we should get 3*nBaseFee or 3 coins for a transaction with 2000 bytes. I think that is fair? I dont know what a common huge transaction is that would make the fee higher?

[sidhujag]

Anyways for now the pushed version 1.0.6 (WINDOWS 32  ) is the one we should test with... min fee is 1 coin and seems 0.2 fees to send coins back and forth (the normal 225-230 bytes) peer to peer transactions.

IsDust picks up transactions smaller than 546.00 uDVC and doesn't allow them to be sent (value too low).

[markm]

We have always had free transactions, I think, haven't we?

Or maybe it was just taking a fee without telling me?

I have had sends to Vircurex take many hours to get confirmations, I had always figured that was because they included no fee.

Dust protection is supposed to force a few on tiny tiny transactions, not slap on a tiny fee on all transactions.

I am not positive though.

But I routinely all along have sent transactions of millions of coins at a time without seeing any mention of any fees.

Think of referrals as a way to permanently tip another user that has helped you. You can earn a minute percentage of fees/points for folks you refer, but they must use your referral code when they sign up.

1. Cryptsy.

If anyone would like to trade DVC at Cryptsy and hasn't signed up yet, please consider using my referral code https://www.cryptsy.com/users/register?refid=46 to sign up.

You can also enter my referral ID ceb9475ab6f51ade79b2fbee2dcbc059fe0b9159 if you don't have anyone filled in to that field yet.

Disclosure: I would ideally receive a Cryptsy Points for trading activity that you perform. I'm not sure how much or even if they can be used for anything yet.

2. Vircurex.

My referral URL is https://vircurex.com/welcome/index?referral_id=991-14430. Please consider signing up for Vircurex if you have not done so thus far. In my opinion, it is the best place to buy and sell DVC.

3. Crypto-Trade.

My personal referral link is https://crypto-trade.com/ref/eeharris.

I would encourage everyone to share their information or perhaps unthinkingbit would allow us to post our referral links on our Devtome pages under the Tips section.

EDIT: I apologize if this is considered panhandling or hoboing. I think all the Devtomers should be supporting each other with this feature.

i've been around for long enough to experience volatility in all its forms.

I'm totally ok with it now. I do not want total predictable reliable price stability.

I want to get a fair amount of value for open source projects funded.
The coin says that '90% of miners profits' are given away to fund those projects, right?

Maybe you can try to guarantee a minimum payout expressed in a more stable currency and then offer the payout in DVC. That would require store DVC in large quantities that could become a problem.  But it is still feasible.

When and if the price stabilize then you can offer random payouts, but now... it doesn't make much sense.  Not only the price of 1DVC is volatile, but even the number of coins per shares :\

I agree, the only way that someone is going to make a very expensive Devcoin ATM is if the business model of making the ATM is feasible. The 96 share bounty will simply be a bonus or a thank-you for a job well done.

My guess is there will be some company out there who makes an ATM at can accept a wide variety of crypto and Devcoin will simply be one of them.

~2 cents~

Something like a coinpayments with a logo saying wr accept coinpayments! Meaning any alts like dvc can be used to fund your account.. We should talk to coinpayments and push for people to accept coinpayments not just dvc.. and work with coinpayments to get more marketing exposure on their website so that people will start to prefer dvc as the defacto payment on their system..

That way if atm accepted coin payments it wiuld be a win win for dvc.

We have to be careful with this. We might end up with an ATM that has 6500 different logos of currency/crypto/card types that are accepted. One could spend 15 minutes trying to find the right logo to see if they can use the machine or not.  


Yeah, it will probably be a company like Coinpayments and some specilized ATM maker that get together and squirt out some type of  hybrid ATM that can accept cryptos. Making it might be the easy part. The hard part will be trying to convince store owners to put this machine somewhere.

Leverage the share system put them on the receiver list.. we can pay for extra exposure.. give shares to store owners for x rounds to give incentive to use ones that support devcoin.

I think that Coinpayments should probably get some shares on the receiver list as long as they accept Devcoins as payment. It could provide them some incentive to continue to do so.

There could also be an agreement to provide them a specified bounty for a website uupgrade and advertising of their services. I think the next logical step by Devcoin would be to take the bull by the horns and have partial ownership of a payment processor such as Coinpayments. I know the market cap is small right now but there could possibly be room for a 10% to 20% ownership stake if the price was right.

The dust fee was always there but no box shows up it just sends it with the fee since it is small... It is now 0.2 dvc as 1 basefee is 1coin as market cap rises this makes sense.

The small transactions that are dust arent even allowed to send now..

Dust protection has to be a tiny fee on all transactions, otherwise an attacker could send medium amounts to himself many times. I don't know if the code was enforcing fees on all transactions, but that was my intent.

Oh okay, I guess I just had not noticed the fee since it wasn't actually saying anything about it (like this will cost X in fees, send anyway? or whatever).

I guess bitcoin only used coin age to prevent the sending to yourself around in circles approach to spamming/bloating the blockchain.

Not sure why we thought that wasn't enough to work for devcoin too though.

(Maybe bitcoin didn't have the coin-age parts back in those days?)

Essentially they just enabled isdust function which throws the tx away or some other weird logic inside wallet.cpp that increases the fee until it gets high enough to be acceptable and another that adds fees if your close to the creation of a block?

since btc dust in devcoin codebase turns out to be under 526 uDVC medium amount are still very low in terms of btc or usd so we need to add a valid fee to deter devcoin dust.. This is valid on something like under a few hundred devcoins.. im seeing this howver wekkel is reporting he doesnt get the confirmation for 1.2dvc fee on small transactions like 10dvc like I do.. it sent it for 0.2 dvc fee.. Id like 1.0.6 to be used be a few ppl to ensure it works as I expect and like it worked on my machine.

I didn't know it was using coin age to stop that. In any case, even if coin age can stop dust, free transactions are still a cost on the network.

Absolutely. Bitcoin had been promoted as no transaction fees so kind of had to use coin-age instead of all transactions having a fee.

We don't advertise free transactions hopefully so aren't thusly constrained.

[weisoq]

I've only ever noticed a flat 1 dvc fee. Perhaps with very low sums it differs. Makes sense to not have any transactions actually prevented as risks having to change code again in the event that price rose significantly or micro-payments become very popular.

[Hunterbunter]

Let me put you through an example: Say I want to build a DVC ATM machine (ndr: which I do want, and I have skills, tools, people, and time ) .  
It takes a lot of effort, work, components, people and skills. There is a  96 shares pending bounty on it.
But before digging into the project and starting taking my time out of other paid projects, buy materials and hire people I want to make some math.  
The problem is.... I can't! 96 shares could be anything between 2k$ and 25k$ by the time I'm done. Right?
It doesn't make sense. I created a certain value for the community and I would like to receive a fair value back. Not just a random number.  Don't you think so?

At some point, 96 shares may be worth between $25k and $250k, or $250k-$2.5m. The first person/group who can produce the bounty economically will do so, including or excluding the bounty in their business plan - which is a risk in itself, since if they're second to market, they must rely on market demand alone (or perhaps a reduced bounty). There is no guarantee the price will ever get that high, but the point in time it is produced will be the moment that someone finds the risk acceptable and goes for it.

Sidhujag get 48 shares provisionally, on the condition that a code report shows that the changes are the same as that of the most recent source from Twobits:
https://gitorious.org/devcoin/devcoin

The changes must be identical or else there could be a network fork. Since we now need a quick code report, the bounty for that has been boosted to 12 shares for the first report and 6 shares for the second report.

Hello,

Here's a detailled code report.
I took ALL the commits made by Twobits or twobits in the devcoin client.
I made a list from all the changes made by twobits and compare with the code of Sidhujag.

Before reaching to a conclusion I would like comments from Sidhujag on my code report. Now I can't show if changes are the same or not (fork or not fork ?)   

Cyke64

The first difference about the timestamp on bip30 I think that is to avert a potential problem in the future so since blocks are already created and patch is applied I think its safe? Unless someone can prove me wrong?

On the blockcount to height rename etc looks like simple rename if these are rpc calls We just need to ensure that the merged mine proxy doesnt make the old calls. i downloaded latest one from i0coin and dbl checked with namecoin so it will use renamed rpc calls if thats the casse. i will check.

Do merged mine pools run thru this merged mine proxy in the contrib folder?

The main stuff is the createnewblock processblock where the reciever stuff is the small changes there but we already talked about that... Am i right in saying that since i take a fresh database and fill it with the blockchain from block 1 and it downloads all blocks that the block processing and bip stuff is all good?

Merged mining will test any rpc differences since i did internal mining I didnt jog the getworkaux stuff. You can merge mine on testnet too using the nerged mine proxy and the three nodes I have setup in the src folder just run the three batch files and then comnect the proxy.. Then point miner to proxy.. Getworkaux gets called but i got no new blocks i thought ut was a setup issue since my network is locked down from blockchain downloads on my dev machine.

Did you look at the devtome technical page and compare with new code? Also receiver.h was changed did you catch that?

Aug 20 2013   #ce01e7a  match rpc port change to 52332 in official repo (twobits)
src/init.cpp (2) -+
src/rpc.cpp (6) ---+++

PROBLEM :
port used by RPCPORT is always 52332 (there's no testnet) in twobits instead of bitcoin RPCPORT 8332.
In Sidhujag , port used is 7332 defaut and for testnet 17332 (src\bitcoinrpc.cpp,src\init.cpp)
Could it be the source of your problem ?

Did you look at the devtome technical page and compare with new code?"

CreateNewBlock

Everything is correct (like twobits)
I check out also the GetKeyID function you used instead of finding the hash160.

pblock->vtx[0].vout[0].nValue = GetBlockValue(pindexPrev->nHeight+1, nFees);
   txNew.vout[0].nValue = minerValue + nFees;
in devtome wiki technical

But in all codes (twobits,Sidjuhag) , it's  pblock->vtx[0].vout[0].nValue = minerValue + nFees;
so wiki content should be corrected with the right assign statement.

GetNextWorkRequired
code contents are the same except your difficulty rule code for testnet you added.

generation rate

devtome wiki :
//static const int64 MIN_TX_FEE = 50000;
static const int64 MIN_TX_FEE = 500000000;
//static const int64 MIN_RELAY_TX_FEE = 10000;
static const int64 MIN_RELAY_TX_FEE = MIN_TX_FEE;
//static const int64 MAX_MONEY = 21000000 * COIN;
static const int64 MAX_MONEY = 21000000000 * COIN;


Twobits | Sidjuhag :
static const int64 MAX_MONEY = 21000000000 * COIN; | static const int64 MAX_MONEY = (int64)21000000 * (int64)1000 * COIN;
static const int64 COIN = 100000000; | static const int64 COIN = 100000000;
MIN_TX_FEE  | int64 CTransaction::nMinTxFee = COIN;
MIN_RELAY_TX_FEE |   int64 CTransaction::nMinRelayTxFee = COIN;

MIN_TX_FEE = MIN_RELAY_TX_FEE = 500,000,000 but in Twobits and Sidhujag values are
100,000,000 = COIN
Why ?

Disbursing the Share
Code is the same.

receiver.h was changed

Yes but I don't see any problem (you add code for testnet and some debug code)

I'm waiting for your comments about this code report

Unthinkingbit's original approach to the second to the post problem was to award bounties to the first few of a thing instead of only to the first.

I have seen that for pretty much all the bounties that I have noticed. Is that not the case with the ATM bounty or is that approach not a good one?

-MarkM-

[sidhujag]

Sidhujag get 48 shares provisionally, on the condition that a code report shows that the changes are the same as that of the most recent source from Twobits:
https://gitorious.org/devcoin/devcoin

The changes must be identical or else there could be a network fork. Since we now need a quick code report, the bounty for that has been boosted to 12 shares for the first report and 6 shares for the second report.

Hello,

Here's a detailled code report.
I took ALL the commits made by Twobits or twobits in the devcoin client.
I made a list from all the changes made by twobits and compare with the code of Sidhujag.

In twobits commit , the rule applies to all blocks whose timestamp is after March 15, 2012, 0:00 UTC (1331769600)   
   and on testnet it is enabled as of februari 20, 2012, 0:00 UTC. (1329696000)
In Sidjuhag version , for DVC the rule BIP30 for Devcoin will go into effect on 2013-09-01 0:00 UTC (1377993600)
I think that Sidjuhag version is correct !

https://gitorious.org/devcoin/devcoin/commit/fd07754b44b6fb4d4f402085c9321f9cfbff6737

ok (no stack random macro implemented in util.h and not used in any files !)

src/db.cpp (2) -+

ok (change applied in   void CDB::Flush() in Sidjuhag version)

src/irc.cpp (1) -
* no irc.cpp file in Sidjuhag version !

src/net.cpp (4) ----
ok (macro not used)

src/rpc.cpp (1) -
ok (macro not used in rpcblockchain.cpp)

src/util.h (13) -------------
ok (no stack random macro implemented)

Before reaching to a conclusion I would like comments from Sidhujag on my code report. Now I can't show if changes are the same or not (fork or not fork ?)

The first difference about the timestamp on bip30 I think that is to avert a potential problem in the future so since blocks are already created and patch is applied I think its safe? Unless someone can prove me wrong?

On the blockcount to height rename etc looks like simple rename if these are rpc calls We just need to ensure that the merged mine proxy doesnt make the old calls. i downloaded latest one from i0coin and dbl checked with namecoin so it will use renamed rpc calls if thats the casse. i will check.

Do merged mine pools run thru this merged mine proxy in the contrib folder?

The main stuff is the createnewblock processblock where the reciever stuff is the small changes there but we already talked about that... Am i right in saying that since i take a fresh database and fill it with the blockchain from block 1 and it downloads all blocks that the block processing and bip stuff is all good?

Merged mining will test any rpc differences since i did internal mining I didnt jog the getworkaux stuff. You can merge mine on testnet too using the nerged mine proxy and the three nodes I have setup in the src folder just run the three batch files and then comnect the proxy.. Then point miner to proxy.. Getworkaux gets called but i got no new blocks i thought ut was a setup issue since my network is locked down from blockchain downloads on my dev machine.

Did you look at the devtome technical page and compare with new code? Also receiver.h was changed did you catch that?

result.push_back(Pair("blockcount", blockindex->nHeight)); | result.push_back(Pair("height", blockindex->nHeight));
result.push_back(Pair("hashprevious", blockindex->pprev->GetBlockHash().GetHex())); |  result.push_back(Pair("previousblockhash", blockindex->pprev->GetBlockHash().GetHex()));

not important because these pairs are only used here locally in this file (no definition in another place)

Here are more details and check about BIP.

Aug 20 2013   #ce01e7a  match rpc port change to 52332 in official repo (twobits)
src/init.cpp (2) -+
src/rpc.cpp (6) ---+++

PROBLEM :
port used by RPCPORT is always 52332 (there's no testnet) in twobits instead of bitcoin RPCPORT 8332.
In Sidhujag , port used is 7332 defaut and for testnet 17332 (src\bitcoinrpc.cpp,src\init.cpp)
Could it be the source of your problem ?

Did you look at the devtome technical page and compare with new code?"

CreateNewBlock

Everything is correct (like twobits)
I check out also the GetKeyID function you used instead of finding the hash160.

pblock->vtx[0].vout[0].nValue = GetBlockValue(pindexPrev->nHeight+1, nFees);
   txNew.vout[0].nValue = minerValue + nFees;
in devtome wiki technical

But in all codes (twobits,Sidjuhag) , it's  pblock->vtx[0].vout[0].nValue = minerValue + nFees;
so wiki content should be corrected with the right assign statement.

GetNextWorkRequired
code contents are the same except your difficulty rule code for testnet you added.

generation rate

devtome wiki :
//static const int64 MIN_TX_FEE = 50000;
static const int64 MIN_TX_FEE = 500000000;
//static const int64 MIN_RELAY_TX_FEE = 10000;
static const int64 MIN_RELAY_TX_FEE = MIN_TX_FEE;
//static const int64 MAX_MONEY = 21000000 * COIN;
static const int64 MAX_MONEY = 21000000000 * COIN;


Twobits | Sidjuhag :
static const int64 MAX_MONEY = 21000000000 * COIN; | static const int64 MAX_MONEY = (int64)21000000 * (int64)1000 * COIN;
static const int64 COIN = 100000000; | static const int64 COIN = 100000000;
MIN_TX_FEE  | int64 CTransaction::nMinTxFee = COIN;
MIN_RELAY_TX_FEE |   int64 CTransaction::nMinRelayTxFee = COIN;

MIN_TX_FEE = MIN_RELAY_TX_FEE = 500,000,000 but in Twobits and Sidhujag values are
100,000,000 = COIN
Why ?

Disbursing the Share
Code is the same.

receiver.h was changed

Yes but I don't see any problem (you add code for testnet and some debug code)

I'm waiting for your comments about this code report
Cyke64

The fee was coming to 5.5 dvc for transactions per 1k bytes I think bitcoin fees were scaled down? When I changed the fee down to 1 coin from 5 coins they now make sense. The dust fee is 1\10th of 1 coin per vout. So if you set multiple recipients in your transaction like create 5 new address and set small amount to each you will see a 0.5dvc fee plus 1 coin so 1.5 dvc fee..

[Wekkel]

Ok, tested the payment fees again. When sending 8 DVC, no message from my client (it sends the payment right away). At 7 DVC, the client informs me that a 1.2 DVC fee will apply. I have not investigated further into decimals.
