Is there anyone who is willing and able to download a copy of bootstrap.dat from me and make a torrent of it please?

Triple check that it is the correct chain, and then go ahead and possibly upload it to the repository?

It's the correct chain.

I modified clamd to have a new command, "makebootstrap", which dumps a bootstrap.dat file containing all blocks up to a specified height, then ran:

./clamd makebootstrap /tmp/bootstrap.dat 176750

Then I shut down clamd, renamed my .clam folder so I had no blockchain, made a new .clam folder, but the bootstrap.dat in it, and ran "clamd -connect=127.0.0.1" to prevent it from being able to connect to any peers, and it started very quickly importing blocks from the bootstrap file:

Code:

keypool added key 99, size=99
keypool added key 100, size=100
keypool added key 101, size=101
 wallet                 8471ms
ERROR: ProcessBlock() : already have block 0 00000c3ce6b3d823a352

ProcessBlock: ACCEPTED

So it seems to be working fine.

I'm now uploading the bootstrap.dat to Amazon S3.

I'll post a torrent link once it's done.

It's still uploading, but if you already have a full copy of the correct fork of the CLAM blockchain, you can create your own bootstrap.dat file by building from this branch:

  https://github.com/dooglus/clams/tree/dumpbootstrap

or merging this pull request:

  https://github.com/nochowderforyou/clams/pull/56

and then running this:

  clamd makebootstrap /tmp/bootstrap.dat 176750

It should make an identical file, which you can use to seed the torrent I'll be posting a link to soon without having to download it.

To check, see if the sha256 hash matches mine:

$ sha256sum /tmp/bootstrap.dat
3965815c11e4cbdafe99ebb55448c7a4abe730e0e8bd6fc42cf2b031cef32443  /tmp/bootstrap.dat

[dooglus]

I'll post a torrent link once it's done.

Here:

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

and here, if you want a direct link, rather than a torrent:

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

Download that, copy it to your clam folder (where the wallet.dat lives) and restart the CLAM client. It will notice the bootstrap.dat file, and import the blockchain up to block 176750 219000 from it. Then it will connect to peers and carry on from there.

need help really bad here... wasted so much bandwith on the last attempt to resynch
the block still stuck @171046 wrong fork and won't fixes itself eventhough I let it run and consumed 300 MB bandwith
my logfile spammed by hundreds of this same errors:

received block 433bcffd6b53c4ddb502

that block 433bcff is block 170622 on correct chain, but why my client is spouting those error messages?
what makes my client downloads so much data & not resync the correct chain?
are there some nodes out there running wrong fork deliberately just to screw us up?
sorry guys... I'm a bit frustrated trying to get my CLAM back on the main chain

is there a way for me to remove a few blocks (something like rollback) from my chain?
if possible I want to try disconnect all blocks starting from 170000+ and try to resynch again
or is it possible to use my own blk0001.dat (maybe rename it first) & import only up to block 170000, then go online and resynch the rest?
something like "-loadblock=oldblk0001.dat" but how do I set it just to import up to 170000?

try the bootstrap provided by dooglus

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

rename clam folder so no blockchain, make a new clam folder, put the bootstrap.dat in it, and run "clam-qt.exe -connect=127.0.0.1" to prevent it from being able to connect to any peers

Using the -makebootstrap RPC command I wrote yesterday you could make a bootstrap.dat containing blocks up to 170000, then make a new clam folder and initialise it from the bootstrap file you made.

That would save you having to download the blockchain over again, but would require you to build the CLAM client yourself.

thanx dooglus, I was stuck for ages , but your above method works great

so thanks again!

has staking been disabled now then ?

thanx dooglus, I was stuck for ages , but your above method works great

You're welcome.

The lottery has been disabled. It used to be that you got 0.1 CLAM almost every time you staked, but occasionally you got a much bigger reward, up to 1000 CLAM. The long-term average was meant to be 1 CLAM per stake.

It turns out the lottery was exploitable and so now everyone gets 1 CLAM per stake (plus any transaction fees for transactions you include in the staked block).

Some block rewards before the lottery was suspended:



And after:

[ymod123]

try to download new update fix Google browser blocking it...

[Karn]

Seem's like a good time to be buying, price is dropping almost daily but wont take much to shoot back up  

[freedomsr40]

so with no lotto how does this work? whats the %? or how does the 1 clam payouts work?

[istvandv]

thanx dooglus, I was stuck for ages , but your above method works great

so thanks again!

has staking been disabled now then ?

which method did you use? did you use the boostrap provided by dooglus? or did you make your own bootstrap using the client provided by dooglus with -makebootstrap?

[istvandv]

so with no lotto how does this work? whats the %? or how does the 1 clam payouts work?

all stakes are now 1 clam, there is no percent, thats as simple as it is

[freedomsr40]

1 clam..but how often?

[1MCoin]

POC OR POP,WHICH ONE DO YOU WANT?
btw,what does"CLAMS"mean?

[istvandv]

1 clam..but how often?

target block time is 1 minute

so 60 blocks/clams per hour
1,440 blocks/clams per day

[istvandv]

POC OR POP,WHICH ONE DO YOU WANT?
btw,what does"CLAMS"mean?

Caritas, Libertas, Aequitas, Monetas

if Im not mistaken
