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

[donarito]

bought some coins, price is moving very well, so planning to buy some more

[coinstash]

Clams will be added to the next release of the Bitsquare P2P exchange, v0.4.9.7 due out in about a fortnight.

That is some good news!

[inkha]

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

This works... using the regex from Nixsy:

Code:

$regex = "/^[x][a-km-zA-HJ-NP-Z0-9]{26,33}$/";
if (preg_match($regex, "xWEWfhF9hDvKksvWgFj6kmseLYShZG9Kx8")) {
    // match success
    echo "Found a match!";
} else {
    // If preg_match() returns false, then the regex does not
    // match the string
    echo "The regex pattern does not match. :(";
}

Helpful, saved aswell thanks!

Code:

function validateAddress($address){
  $regex = "/^[x][a-km-zA-HJ-NP-Z0-9]{26,33}$/";
  if (preg_match($regex, $address)) {
      // match success
      return true;
  } else {
      // If preg_match() returns false, then the regex does not
      // match the string
      return false;
  }
}

I Have saved this to my snippets folder, Thanks dude.

You could replace the 0-9 with 1-9 because we don't allow 0's in CLAM addresses.

I have no idea bout these shits but I think you could use the bootstrap that dooglus updates regularly, Ill search the link and update.

I've run into this problem before too. I think it may be because peers are sending you blocks out of order, so rather than extending the end of the chain in a consistent sequence, you're building up fragmented bits and pieces of the whole thing. The client only keeps track of 750 orphaned blocks by default, and after that it just ignores any further ones it sees (thus the string of error messages). An orphaned block is one that doesn't have any link to your local blockchain, but that doesn't mean it's necessarily invalid, as a future sequence of blocks could include that link and properly connect it into the blockchain.

Bootstrap information is here, hopefully that will help: https://bitcointalk.org/index.php?topic=623147.msg9772191#msg9772191

I just updated that bootstrap post with an up-to-date copy of the blockchain.

I think you're right about the cause of the problem. The blocks arrive out of order, the client keeps up to 750 new blocks in memory while it waits for the missing older blocks to arrive, but is only willing to keep 750 in memory before it starts ignoring out of order blocks.

I think rebasing the CLAM client from a newer release of the Bitcoin client would solve this problem. I also think xploited is in the process of doing exactly that. You can see his work on the 'reindex' branch of his own github repository, here:

    https://github.com/l0rdicon/clams/tree/reindex

Hopefully he'll merge his work onto the release branch some time so everyone can benefit from the improvements.

Increasing the size of the orphan pool can help, to a certain extent.
Orphans are also not 'ignored' once the pool is full; they are randomly ejected.

Here is a cmdline arg to expand the size of the orphan pool, in terms of count:  

Code:

-maxorphanblocks=<n>

I believe novacoin or blackcoin have an implementation that uses the size(data) of the orphan pool, which makes more sense considering that blocksize itself can vary quite a lot.  

However, I don't personally believe that this is the entire story.  
Doing a diff between ppcoin, novacoin, blackcoin, or another codebase close to ours reveals only a handful of differences in terms of sync code.

Of course, rebasing to a more current Bitcoin codebase would almost certainly help as dooglus has noted - as the BTC network doesn't display the same problem.

[krile]

I made an updated bootstrap.dat file for people having trouble syncing their client.

It goes up to block 1220900 which was staked on Sun Oct 23 17:29:04 UTC 2016.

It's available as a download here:

  bootstrap.dat

Tnx for the link. Flying now with the bootstrap

Even though syncing through the p2p network would be slow it would be done by now if it weren't for the 750 orphan limit. Its been almost four days now, as a test I left it running, I noticed that very slowly new blocks were getting in, but at a rate of maybe a 1000 a day - which is silly.

This really should be fixed.

[gamblingbad]

Is there a recent chart over staked and mined coins?

Is there a recent chart over staked and mined coins?

Chart most certainly not but you can use /supply on the just-dice chat to see the whole.

I think it will be fixed in the next release.

I saw a request for a CLAM supply chart and noticed I hadn't run my local copy of the CLAM client for 20 days or so. I'm using the code on xploited's "reindex" branch and just watched it sync the last 20 days' worth of blocks (a total of 30101 blocks) in 34 minutes. That's not too bad:

[Edit: I'm on a very laggy Internet connection, and was connected to only 4 peers]

I heard recently that he's pretty much ready with the new release, so hopefully we'll see it soon.
