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

It goes up to block 419140 which was staked on Sat Apr 11 02:15:12 2015 UTC.

https://s3.amazonaws.com/dooglus/bootstrap.dat

or

https://s3.amazonaws.com/dooglus/bootstrap.dat?torrent if you want to download it using BitTorrent.

Download it, put it into the same folder as your CLAM wallet.dat, then restart the client.

It will take a while to import it, but it will be a lot faster than trying to sync using the p2p network.

When it is done, the client will rename the file to bootstrap.dat.old and won't look at it again.

Once it has been renamed you can delete it if you like.

To verify that you have the right file:

$ sha256sum bootstrap.dat
90be19e7d39a8620be2f62726736f55a19857b7306ceeed6440de72d354fe89b  bootstrap.dat

Just confirmed the hash myself...

Code:

me@XX:~$ clamd dumpbootstrap ~/bootstrap.dat 419140
me@XX:~$ sha256sum bootstrap.dat
90be19e7d39a8620be2f62726736f55a19857b7306ceeed6440de72d354fe89b  bootstrap.dat

Thanks.

I don't think there's much an evil actor could do to you by crafting a "wrong" bootstrap.dat file. You would download it, the client would import it and either find that it was valid or it wasn't. He couldn't just change random bytes to give himself more coins, because then the blocks wouldn't validate. He could stake his own separate fork of the chain and upload it as a bootstrap.dat, but if it didn't have a higher cumulative difficulty than the chain on the rest of the network it would quickly be replaced by your client.

But it's good to have confirmation anyway.

Dooglus - you do not suffer from "trust issues" here but thought I would confirm it for fun

Clams has now been added to the CoinWallet.co online wallet service.

That's great news.

I'm wondering the same as BayAreaCoins:

What percentage of the staking reward do you give to your depositors?

Because each currency works off a single client wallet the system works the same as a personal wallet in terms of staking. This means staking rewards are assigned to initial transaction addresses and change addresses. So currently it is a bit of a lottery - but we do not withhold any percentage of the staking reward...

I have several ideas to improve this, so users always get 100% of their staked rewards. One way to do it is from the database, so any generated coins get split between all holders dependant on total percentage of mature coins they hold in the system at that point in time. The other is to move to a manual transaction system so change can always come back to the originating address and staking is assigned by address. Each method has its pros and cons. The first method would mean more of a staking 'pool' where all holders of X coin get a percentage of all staking rewards.

It's on the todo list.

I think the "staking pool" way is the obvious way to go. It lowers variance for everyone. Instead of waiting 8-12 days to stake 1 CLAM, I stake 0.1 CLAMs per day and have a much more regular predictable income.

Just-Dice does a similar thing for its investors, but takes 10% of the rewards as a fee and so should be easy enough to compete with. Then again JD doesn't charge a (significant) fee for withdrawals.

Working on it now, should be ready in a couple of days.

I need a new CLAM address for the Just-Dice bankroll.

The previous one I was using was xJDCLAMZ9rQ11tMf7JUw1Zzvjm5ShkryrU and I would like the new one to start with the same 8 characters, all uppercase except of course for the 'x':
xJDCLAMZ

I'm offering a 100 CLAM bounty for the first person to generate such an address for me. You can generate addresses using vanitygen (https://github.com/samr7/vanitygen.git). You need to patch it to work with CLAM: https://bitcointalk.org/index.php?topic=623147.msg8875631#msg8875631

And so that the private key stays private, you need to run vanitygen with these flags (the -P in particular is the one that makes is safe):

Code:

-X 137 -P 04A56E39954B155CE4B79E72CD72854F114C3D5E1C7A3B1035D8EA5C836529004CDDCF7DA674B579BBBA49D49021C420235FD3A139C052D261DB4F85AE3B51EB9B xJDCLAMZ

The prize goes to the first person to post a working private key in the Just-Dice chat tab.

I'm clearly misunderstanding something here.  Why would you move money into an address whose privkey was published publically?

[dooglus]

I'm clearly misunderstanding something here.  Why would you move money into an address whose privkey was published publically?

When I asked for people to search for a privkey, I gave them the public half of a keypair I generated. They use that public key in the -P argument to vanitygen. They give the privkey that vanitygen finds, and I combine that with the privkey from the pair I generated to arrive at the real privkey for the address.

Without knowing my privkey the publicly published privkey is useless.

(also include your CLAM address in the post too!)

All CLAM to Silver shipments over the weekend were sent out today!

Thanks guys & gals.

Thanks for the education, dooglus!  If you don't mind my following up, I understand from this that you generate a keypair, public and private:

1. pubA ,privA

Then your friends run vanitygen -P to search for a private key

2. vanitygen -P pubA --> privB

Then you somehow combine privB privA

3. doogCombine(privB, privA) --> privC

And privC is a valid private key to go along with pubA?  I'm sorry I'm so dense.  Of course if you don't want to get into the technical details here (perhaps it's too far afield) and you have some links to reading I should do instead, that would also be much appreciated.
