[DVC]DevCoin - Official Thread - Moderated

[sidhujag]

Sent 1,000 DVC from 1.0.8 Windows client to Vircurex. Not shown in the block explorer yet.

Sent 94 DVC (triggered 6 DVC payment fee) to my (older) Linux wallet. Not shown in the block explorer yet.

No sign yet of your 1,000 into here (my Linux wallet).

It seems we both cannot get the 1.0.8 client to register payments into the network.

I exported my private key and imported it into a new wallet, I was copying my wallet.dat and running different versions so the client threw a fit thats why my sends weren't going thru.. but now I sent you and vircurex some coins and they are being posted on the blockchain. My vircurex account has received the funds.

Here is a transaction to you for 12k dvc:

please confirm that your sends of 100 and 94 worked.

Some questions for the (armchair or otherwise) economists out there:

What is the intention behind used coins, when it comes to devcoins?

I should probably quantify what I mean by "used". It's those coins which people have purchased simply to inject cash into the devcoin system so developers can be paid - be they the devcoin admin team buying them from advertising revenue, or philanthropists which have more money than they know what to do with and wish to support open source development. They buy the earned coins off developers (giving them their pay), and then what? Is the intention for them to add them to wallets and leave them there forever?

What "use" are coins like these? A token to measure karma by before the gates of heaven?

What I want charity investors to do is hold the devcoins unless they have a financial emergency, or until devcoin rises in price enough that we can accomplish all the potential bounties:
http://www.devtome.com/doku.php?id=devcoin_bounty#capitalization_10_000_000_000_usd

If devcoin ever does reach a market capitalization of 10 billion, devtome would be the largest wiki ever and would get a lot of revenue. At that point devcoin would have value as a regular investment, not just charity or speculation, and investors could sell their coins if they wished without affecting the price much.

You say that the 96 shares for the first to make an open source DVC ATM machine should be only a side contribution. Moreover you want the ATM to run both ways (cash2dvc and dvc2cash).

I was pointed out that a one-way ATM will receive only half of the shares. I cannot stop to emphasise how hard it is to achieve such thing. The top todays manufacturers which are well funded, closed source and ship the ATM for freaking 4k$, only managed to build it one way. http://www.coindesk.com/lamassu-ships-first-bitcoin-atm/ .

If you really want to encourage me or others around to build an open source one, that cannot be done with a 'side contribution'.

That means that devcoin is not currently worth enough to fund an open source ATM. Devcoin is not worth enough to fund any but the simplest of hardware, like simple toys:
http://www.devtome.com/doku.php?id=devcoin_bounty#capitalization_1_000_000_usd

I prefer not to make bounties for expensive hardware, which devcoin can not fully fund. I only made the bounty because someone asked for it.

[Unthinkingbit]

..
Who tested the spam-proofing?

I do not recall even hearing about any attempts at spamming, nor any analysis of how much it would cost to achieve how much of what kind of effect by spamming.

I never posted an analysis, but worked out that because of the low price of devcoin, the minimum fee should be 5 * Coin to make spam too expensive. I want to keep the fee at 5 * Coin, I just assumed I had to reduce it because Twobit's clients must have made some blocks. If it is possible to keep the fee at 5 * Coin, then it will be kept there.

Maybe spammers have been holding off a while anticipating it becoming five times cheaper to spam so are waiting until more than 50% of the network is ready to let them spam cheaply?

The only coin I heard of that was attacked by spam was litecoin. I added the change so that we'd be safe.

Devcoin is not really up a lot in price compared to bitcoin, so as long as we simply use 1000 (or maybe nowadays 2000 would be better now we mint 2000 times as many coins as bitcoin) we should continue to inherit bitcoins' analysis and calculation of how much the various aspects of fee ought best be set to.

Right now devcoin is worth roughly one millionth of a bitcoin, so proportionately to value our fees would be a million times higher. On the other hand, far fewer people hold the devcoin block chain, so we could be cheaper, by say a factor of a hundred making our fees about 10,000 times higher.

This is why I have always figured we'd just be doing the same usually changes to bitcoin code that we did originally: multiple all their span fix figures by a multiplier intended to reflect jow much less than a bitcoin we expect a devcoin to be worth.

Presumably we'd also inherit their expert analysis of which changes are forking ones that need to come into effect at a certain block number, as we'd see that when they changed their fee they did or did not do it as a change set to come into effect at a certain block.

For some ideological reason, a lot of bitcoin people want free transactions, which is a mistake because all transactions, no matter how legitimate, add to blockchain bloat. It's a mistake which altcoin developers have to fix.

Whoever runs this site: http://faucet.d.evco.in/

You have some things to take care of.

1) One of the advertising blocks (the bottom one on the sidebar) keeps forwarding the browser to their site, making it nearly impossible to use the faucet without an ad block/"stopping" the page load before that javascript hits the browser

2) It's not moving forward to new rounds. It now shows almost 300 people signed up for the current round, and after you submit an address it just pops up the "Error! Add your Devtome ID to your signature" or whatever message; it's not even loading the sidebar/footer upon submit

Nope, my 1,000 and 94 payment did not register. Must be something with the 1.0.8 client, but switching back to 1.0.7 did not change anything. Payments seem to register in the client but not on the network (0 confirmations, no show in block explorer). All my payments with the experimental Windows client back to (including) 26 December are not visible in the block explorer.

Something is going wrong.

Do you have an old version of the Windows client for me (let's say: 1.0.3)?

Another review of Max’s http://altcoincards.com/

Purchased a $50 Barnes & Noble eGift Card. Very simple to select and input details (which I just made up, except email). Site forwards to coinpayments.net where you can check info and are given a DVC address and sum to transfer.

Coin payments send through a payment-submitted then funds-received mail, with link to check on progress. Altcoincards provide an order-received page. With 6 confirmations the transaction was complete and I got order receipt within minutes then egiftcard through later. Hadn’t used B&N before, but that part was fine, picking up a couple of music books (modern method & hanson fingerstyle for anyone into guitar) without having to set up an account.

All-in a really nice and attractive site with quite a few options for shopping with Devcoins.

Do you have an old version of the Windows client for me (let's say: 1.0.3)?

Did you copy your wallet.dat file between versions of the client? I did that while testing and it screwed my setup. I exported my private key using dumpprivkey then saved the key.. deleted the wallet.dat then loaded up same client again and called importprivkey on the saved private key and got my coins back.. then sent to vircurex and you and it worked... so a valid test would be to take a machine with old client and simply upgrade to new client and try to send

[Unthinkingbit]

Metazilla is very busy, and has been replying slowly if at all, so I'm suspending Metazilla from being an admin until he has more time. He was handling the share list, so I looked for another programmer who is not already an admin to handle that.

Hunterbunter did good work with the chart and countdown clock, so I asked him to be the share admin and he agreed. To everyone who contacted Metazilla about earning devcoins for development and didn't get a reply, please message Hunterbunter.

_{^{For the avoidance of doubt, I am happy to keep our conversation on the experimental Windows client outside of this thread to avoid anoying the rest. Do you use certain IM software (I can use Google Hangouts but can install something else of course)?}}


I did the following:

1. made back up of wallet.dat
2. started client (upgraded to 1.0.8 again)
3. dumped private key
4. closed client
5. deleted wallet.dat from the Appdata/etc folder
6. started client
7. imported private key

This gives me a strange result. My balance is 10 DVC while it should be 2000+ (if everything from 26/12 until now is not counted). I think that importing the private key does not bring back certain internal changes in the original wallet (see pic below).



Closing the client, reinstating the original wallet.dat, gives me the expected balance again, but with the problem that everything after my donation to the Devcoin counter is not seen by the network (see pic below).

When you copy around wallet files and run different clients on same wallet file it messed mine up so once you overwrote the wallet file with a copied version the dvc cannot be spent for security reasons.

Can you put your dvc address into the
block explorer to see what the balance is? It should match the client balance after import. Maybe blockchain thinks u have only 10?

[Wekkel]

The balance is the same as the client states = 10 DVC. However, according to my own administration, I should have 2.2 DVC now including subtracting a payment of 1,000 today to my Vircurex account.

Let's call the client I worked with today the 'old client' (showing the 2.2 balance, but with payments that do not register). The client I am currently working with is the 'new client' (showing a balance of 10 DVC, which is incomplete). The address I worked with is 18GCTJhxrWfXjnLwwjJKsSYBpyEV16pRsB.

I think the problem arises from the way payments work. Take my 10 DVC payment to Weisoq and the 1,000 DVC contribution to the Devcoin counter on 25 December 2013. These payments show in the old client as a payment of 10 and 1,000 DVC. The 10 DVC payment went to Weisoq's address and the 1,000 DVC to 1HUnznpv5nh91vEzbwvYud9ieeBCgzuscF. The Weisoq payment was made from my regular address, but in fact made a step in between. Looking at the payment details, the following happened. First, the client takes 2145 from my wallet address and splits it into two amounts, each with their own address.  The 10 DVC goes to Weisoq, I presume, and 6 DVC get's lost (I assume as payment fee).

The 2129 is then situated in the address: 14B2RbyRWfu892RJnm7CE3VBMKbZ5R9rNx. The next step is that - from this address and to make the 1,000 payment to the Devcoin counter - the 2129 DVC is splitted again into 1,000 and 1,123. The 1,000 DVC goes to the address of the Devcoin counter (1HUnznpv5nh91vEzbwvYud9ieeBCgzuscF). This is the actual address I used as recipient address. The other 1,123 DVC goes into the address 163eDwvgdhaxiEbCfozF8B81sxsx1o7ri3 which still shows a balance of 1,123 DVC.

I think the problem with my routine of importing the private key is that I do import the private key of my regular DVC address but not the private key of the intermediate DVC addresses that were created over time due to this 'splitting' activity when making payments. Therefore, in the new client I get an incomplete overview of payments and some amounts remain in limbo. In the old client, these intermediate balances show, but as payments already made that do not register on the network.

Essentially, now some 1,000 DVC is sitting in one or more addresses without an option to access this balance. The keys are still in my possession (the original wallet.dat of the old client). I would like to try an older devcoin wallet (1.0.3/4) to see how it reacts to the original wallet.dat file.

I think we should not focus on this, I just want to take out the balance and start fresh again with the current 1.0.8 wallet with a new wallet.dat.

Hehe thats crazy.. I think in the process of our testing multiple versions with different fees and versions old vs new clients that we corrupt our wallet such that it wont match whats on the blockchain.. So then you have to claim balances using your private keys.

However the important thing to test is that we can start with an old wallet funded say 1000 dvc and then simply upgrade by installing 1.0.8 and then thr wallet gets upgraded automatically. This is a trusted process and allows you to spend in the same wallet file via upgrading... so then subsequent sends should work.. send some to an old client like vircurex or your linux address to see if it shows up on the blockchain.. Im trying thos as it will prove that we dont have a fork.

[smeagol]

I downloaded one of the newer clients, none of my generation is showing up and it says "117 weeks behind."

Isit supposed to be like that?

You had entire blockchain already? Check in the debug to see if you have any connections and that blocks are downloading...

Blocks are downloading and I have 8 connections.

I do have the entire block index from the old client though

A bounty update:

If anyone is interested in the open-source toy bounty, there is an excellent modelling software called Tinkercad available here: https://tinkercad.com/.  I believe it is proprietary  but it is free for a limited time: https://tinkercad.com/plans/

For more information about the toy bounty, see http://www.devtome.com/doku.php?id=devcoin_bounty#capitalization_1_000_000_usd

Also, if there are any new and notable DVC businesses opening up, don't hesitate to notify me.  I will soon add altcoincards to the list here: http://www.devtome.com/doku.php?id=where_to_spend_your_devcoins

1) One of the advertising blocks (the bottom one on the sidebar) keeps forwarding the browser to their site, making it nearly impossible to use the faucet without an ad block/"stopping" the page load before that javascript hits the browser

2) It's not moving forward to new rounds. It now shows almost 300 people signed up for the current round, and after you submit an address it just pops up the "Error! Add your Devtome ID to your signature" or whatever message; it's not even loading the sidebar/footer upon submit

Thanks for the info.

1) I can't found anything wrong with the ads, could anyone other to confirm this ?

2) This has been solved. someone want to hack into the faucet and submit unusual data, and cause wrong status of the db.

#1 - it's not every time, but it is pretty often. It's with "bitcoinadvertiser" IIRC that is doing the forwarding. The top block has no problem.

#2 - that sucks, . Someone always has to try to destroy it for everyone...

I do have the entire block index from the old client though

Did it sync up? It should start from
where the old client left off unless it is not
compatible(old database and new database) So in that case it starts over again.. but I thought it doesnt do that.. thats not a problem though as long as you can still send and rcv new blocks after the upgrade.
