[ANN][CLAM] CLAMs, Proof-Of-Chain, Proof-Of-Working-Stake, a.k.a. "Clamcoin"

[dooglus]

It doesn't matter if the client is synced. You should unlock the wallet with the walletpassphrase RPC before trying to sign a transaction. Other than that, maybe you could show more details. What are you typing, and what does the error say? "I failed" isn't helpful.

Here's the random test data I'm using:

From address: xSPPAQsgYTUsiH51xG3u4Shf7Cc7dt5V7g (importprivkey Lo2RApGkaDZDePA347i56Lo4xRNGBwuxUgyQBC5cK9Ea2Kpn2mnt)
To address: xK8vfFyKC4J2SHR2Hhk7whQAaCTGWbEEwW (importprivkey LnE8nFjSGVKhxoo5rxNZnQU31zT2JnDmVNsEEXoA8tq1HoXtJ4DC)
Amount: 3.5 CLAM
TX in which they were received: 71f2cbe9ff92b8c62a2bcfba5dfc9bc32a2d0c71bf55834e6d884b9ab0de201c
Output in which they were received: 69

By the way, I'm using the console window of the clam-qt.exe client. I'm testing on a Windows VM without network that has never seen any Clam install before (and for every test I revert it back to a previous snapshot).
I just start the exe, import the above keys, restart the exe and go to the console window. There's no password set (at least clam-qt never asked for one).

Here's the screenshot of my attempt: http://picpaste.com/iYdNPs6T.png

I'm aware that any other Clams would be a tx fee; I'm just trying to get this to work right now, so I don't bother about fees.

Anybody can help?

Are you there Dooglus?

I am here. I did have a quick look at the addresses and txids you posted but it looked to me like none of them existed on the network.

etc.

So I don't know what you're really trying to do.

I would be helpful if you could copy/paste the whole console session. What commands are you running? What outputs are you getting?

Any hope of getting more exchanges to carry clam? seems like the bottle neck atm. Polo doesnt serve everyone and ShapeShift seems spotty af, it makes clams like a little extra risky :/

I think it's possible to buy them from other people from Just Dice with the escrow method. I'm not sure though, I haven't tried it.

I don't know if anyone has tried. You are free to contact whichever exchange you use and ask them to add it.

Let us know what exchanges you are thinking about wanting to add.

CoinExchange.com is kind of interesting and they don't have limits on Bitcoin withdraws.

I haven't asked exchanges in probably over a year... I last tried to get some Chinese exchanges.

etc.

I would be helpful if you could copy/paste the whole console session. What commands are you running? What outputs are you getting?

Like I said, that's random data I generated (that's why I also posted the private keys so anybody can retry). Since I'm trying to get the whole signing process to work on a system without network access, there is no way for the Clam client to verify eg the tx. That's why I might as well use random addresses and tx. From my understanding, it should not matter if the data is real or not as long as it passes e.g. address verifications.

Btw, I did include a screenshot of the console session before where I tried to create a tx to spend the 69th output. See http://picpaste.com/iYdNPs6T.png
Creating the raw tx works, but I cannot figure out how to sign it correctly, even when I have both privkeys in the client.

[xnyz]

is there any new things going on here?

[dooglus]

See http://picpaste.com/iYdNPs6T.png

Can you copy/paste that in text form?

And show some information about the output you're trying to spend. Output from 'validateoutputs' about it would be useful.

[ders_a]

Honestly speaking I cannot see what is reason for that coin (it is not only one coin without reason, coin just to make one more coin). I am wrong?

p.s. I am small investor and trader. From trading view looks it is dead. Just imo. ok, good thing is support form POLO. but volumes are not huge, not sure how long it will stay on polo

Sure thing; I recreated what I tried before and pasted it below.
"validateoutputs" obviously says not found, but that's a given. Not just because it does not actually exist, but because creating and signing is supposed to happen on a computer that hasn't been on the network so naturally it won't have any tx information at all. If a fully synced client is required, the whole process of offline signing would be meaningless.

My understanding of the process is that you create a valid raw-tx (what seems to work, at least the console does not complain) and then sign it with the privkey of the sender's address so you can use a pushtx service on another (online) computer to send it out. If that signed tx contains garbage (like a non-existant source tx), the miner is supposed to reject it. Please correct me if I am wrong on any of those assumptions.

Thanks for taking a look into that by the way

(btw, the random whitespace in the hex strings seems to get added by the board, it's not there when I copy&paste it. Seems to be forced space after 79 characters)

p.s. I am small investor and trader. From trading view looks it is dead. Just imo. ok, good thing is support form POLO. but volumes are not huge, not sure how long it will stay on polo

This coin is basically equivalent to Just Dice "shares" or casino chips. It could potentially have more uses, which would make it more valuable.

OK, I see what you mean.

I think I mislead you earlier about how to get the scriptPubKey. It isn't just the address' public key, it has to be a whole script. For example:

$ clamd getaddressesbyaccount ''
[
  "xEPEtmoV9nBYiiyoPmLcZFiHheYzLo81Du"
]
$ clamd dumpprivkey xEPEtmoV9nBYiiyoPmLcZFiHheYzLo81Du
Lom7ZtR3SLwU5PtNN9m3eXH7yzF5yv6HnZoZg6GzBoGjnqv5Snrw

}
$

In that example I'm signing a "send to pubkey" script, not a "send to pubkey hash" script. It's using the pubkey directly, not the address, with a "ac" byte on the end for OP_CHECKSIG. (Addresses are basically 160 bit hashes of the pubkey). To sign a regular address script, the script looks like:

  OP_DUP OP_HASH160 <160 bit pubkey hash> OP_EQUALVERIFY OP_CHECKSIG

or in hex:

  19 76 a9 14 <40 hex characters for pubkey hash> 88 ac

So in your case you would do this:

$ clamd signrawtransaction $(clamd createrawtransaction '[{"txid":"71f2cbe9ff92b8c62a2bcfba5dfc9bc32a2d0c71bf55834e6d884b9ab0de201c","vout":69}]' '{"xK8vfFyKC4J2SHR2Hhk7whQAaCTGWbEEwW ":3.5}') '[{"txid":"71f2cbe9ff92b8c62a2bcfba5dfc9bc32a2d0c71bf55834e6d884b9ab0de201c","vout":69,"scriptPubKey":"1976a914c6580bcf8320c3ddaadebc9be9f38ac6fb59d21688ac"}]' '["Lo2RApGkaDZDePA347i56Lo4xRNGBwuxUgyQBC5cK9Ea2Kpn2mnt"]'

  "complete" : true
}

I got the 40 hex characters for your address by base58 decoding it:

I've no idea how it could say it's complete but return the same unsigned tx you started with.
