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

I wouldn't get to nervous about this.  That's one Man's opinion, note the use of the word "imagine".  

Ya I'm totally just rambling

No worries.

Mac fag checking in.  Running 1.4.10 and smooth sailing so far.  Staking and all.  
Curious behaviour as the staking icon goes red more than I've ever seen but I can't
see a problem.

Does it go red for long periods at a time? Long enough that you can hover the mouse over it and tell me what pops up when it's red?

If you put:
debug=stake
in the clam.conf file in the same folder as your wallet.dat and restart, it will write stake-related stuff to debug.log in the same folder as it stakes.

You could "tail -f debug.log" in that folder and see whether anything looks different when it's red. Staking basically consists of hashing each of your staking outputs every 16 seconds and comparing the result with a target based on the network difficulty. If the output hashes lower than the target, you get to stake a block. "debug=stake" will cause these hashes that are being compared to be logged.

I couldn't find an existing one, so I created a clam.conf and added debug=stake.  I'm hoping I did it correctly.  I added a screengrab of data flow. http://imgur.com/Gmcfbf8 When I hover the cursor over the red icon, it sometimes says 0 weight.  And then other times it says not staking because I don't have mature coins.  But then I stake at least once a day.  

Hope this helps.  Thanks for everything!  

/s/

Same thing was happening to me on a previous version (1.4.7 i think)  and the 0 weight was also showing.
I haven't seen it happen to me again yet on this latest version.. but I'll watch for it.

It can stay red for up to one minute, i've seen it myself. When you hover over it says 'Not staking because you don't have mature coins'

It doesn't appear to affect staking in the long run, i always just put it down to new blocks being generated and that it was a normal thing.

I have the debug switch on at the moment so i'll try and upload the debug.log next time i see it happen.

I think I caught a red patch in the debug log.  This is the point where it was red and then normalized:

Any update on why this happens ?   Mine seemed to stay red longer this morning
Edit:  also seems to be happening more frequently (icon turning red)

Edit #2:  Restarted wallet and symptom seems to have mysteriously disappeared (for now?)

[chriswen]

I don't see anything wrong with a linear distribution curve.

With the combination of more people digging up clams and the increase of clams from POS rewards the inflation will decrease over time.

You sold me on POP ages ago but this is excellent

[AdamWhite]

Seems Coinimal is very selective with their coins, they only offer BTC LTC NXT and CLAM

Cool 

[dooglus]

Are fees necessary for clam? If staking is same and not ending over the time ?

I guess part of the point of fees is as a spam-prevention mechanism.

If it cost nothing to make thousands of transactions just sending coins to yourself then that's an easy way for an attacker to bloat the blockchain.

Also, without fees there's no incentive (other than fuzzy "help the coin" incentives) for stakers to include any transactions in their blocks. They would get paid the same whether they stake empty or full blocks, and full blocks take longer to propagate and so stand more chance of being orphaned.

This can change though.

I imagine the block reward will be reduced in the next 2 years or so.

Why's that?

One of the things that sold me on CLAM was the linear distribution curve

 I wouldn't get to nervous about this.  That's one Man's opinion, note the use of the word "imagine".  

   To keep a POS coin network alive you need to have lot's of nodes moving the block chain along.  The people running the nodes need to be compensated for there time and resources.  At present, the transaction fees are increasing, but don't amount to much.  In the last 6 stakes I've made .0014 from the fees.  hardly enough incentive to keep a node running.  

The way I see it, staking your coins is simply a way of "keeping up with inflation". The total money-supply goes up 3% per year, but your CLAM balance also goes up 3% per year and so your percentage of the market cap stays constant - in that sense PoS money-supply is the "good" kind of inflation. It doesn't erode people's savings.

It doesn't really matter what that "3%" figure is, so long as it's big enough to encourage people not to opt out of staking and small enough that the money supply doesn't get too big.

There will always be some people who don't stake their coins, and so by staking your share of the market cap will be going up while their share goes down. That's how it should be, and results in more people supporting the network by staking their coins.

[dooglus]

does anybody know how to validate a CLAM address with PHP?

Probably your best bet is to use something like this to interface with clamd's RPC interface, and call "validateaddress".

Alternatively you can check an address by base58 decoding it, and making sure that the first byte of the result is (whatever it's meant to be, 0x85 I think) and that the last 4 bytes of the result are indeed the correct checksum for the rest of the result. Read about the format of addresses here:
  https://en.bitcoin.it/wiki/Base58Check_encoding

This is the regex to find/check an address

Code:

^[x][a-km-zA-HJ-NP-Z0-9]{26,33}$

Careful - that will tell you that
  xJDCLAMZ9rQ11tMf7JUw1Zzvjm5ShkryrV
is a valid address when it isn't.
  xJDCLAMZ9rQ11tMf7JUw1Zzvjm5ShkryrU
is valid. Note the U on the end.

The last few characters are a checksum to guard against typos. You can't validate the checksum using a regexp.

I'm sorry, I didn't notice your reply until now.

That screenshot looks like it didn't have "debug=stake" in the clam.conf. Maybe you put the clam.conf in the wrong folder, or didn't restart the client after editing it, or something else...

You can run the client with the -debug=stake flag to achieve the same effect without editing any files. When it's set, the logfile should show a bunch of [STAKE] messages every 16 seconds, like this:

That's my two outputs trying but failing to stake yet again.

I'm wondering if your "checking 2 outputs()" count goes down to 0 when the icon goes red, and if so whether the log says anything about it.

[Grumlin]

so, if I will import my priv keys, client does send my priv keys to developers or not?

[BayAreaCoins]

No, but it is better to be safe than sorry.

Just assume it does. 

I know lazy bastards who haven't moved their coins and claimed their CLAM.

With the CLAM client it does it all for you automatically.

[SuperClam]

Are fees necessary for clam? If staking is same and not ending over the time ?

As CLAM grows I believe the block reward can be removed entirely due to high number of transactions with fees + low energy costs.
That's going to be a up hill fight to get the block reward removed and honestly I like the block reward + fees.

As was previously mentioned, transaction fees are an important incentive and Denial of Service feature.


Concerning the perpetual 1 CLAM per block reward, it is designed to replace the deflation of lost or burned CLAMs and provide for a stable and conservative level of additional inflation.

Go to www.Just-dice.com and then the chat box.  Type /dig <address>

That will tell you if it is loaded or not.

Thanks for your help!
I've checked some addresses

ps: I don't own those addresses.

[dooglus]

Do you mean what you said, that you want a list of addresses that have claimed CLAMs?

Or do you just want a way to check for a given address whether it has claimed its CLAMs or not?

They're two different things. Both are possible, but the first one requires access to a block explorer for each of BTC, LTC, and DOGE. We can see a list of CLAM addresses which claimed their CLAMs, but each CLAM address can be converted to exactly one BTC, one LTC, and one DOGE address - so once we know a CLAM address that claimed we need to check all three of the DOGE, BTC, and LTC block explorers to see which of the three blockchains that private key was used on before May 12th.

For example, CLAM address xC6ktEBwaTk8G27wCWwQjGmDuK14SZPvJa has dug up its CLAMs. That CLAM address has the same privkey as LTC address LP25FZfJPQW9USiE2BJ3a7YCtR57DVHk5Y, DOGE address D8wDXcJ7cAANkeCfadJJqre3ZLS8SU2zrY and BTC address 14o7zMMUJkG6De24r3JkJ6USgChq7iWF86. Only one of those three addresses was funded in May 2014, but we need to check the block explorers to find out which it was:

   BTC: http://blockchain.info/address/14o7zMMUJkG6De24r3JkJ6USgChq7iWF86
  DOGE: http://dogechain.info/address/D8wDXcJ7cAANkeCfadJJqre3ZLS8SU2zrY
   LTC: http://block-explorer.com/address/LP25FZfJPQW9USiE2BJ3a7YCtR57DVHk5Y
  CLAM: http://khashier.com/address/xC6ktEBwaTk8G27wCWwQjGmDuK14SZPvJa
