Hi, guys i have a problem...can't sync my qt wallet, it ctuck on 2097394 block...i downloaded v1.4.17 from official site, downloaded bootstrap.dat from this https://bitcointalk.org/index.php?topic=623147.msg9772191#msg9772191 post and put it in folder where my wallet.dat is....it goes fine till wallet renamed it (bootstrap.dat.old) sync stopped on that block...I made clam.conf and add some nodes but still nothing...on client i see a have 16 active connections... "importing blocks" in lower left corner is gone and it's really annoying because i lost 5-6 hours (in last 4 days) on this... Angry
Finally, after 10 days i was able to sync my QT wallet...in 5 years of my mining experience i have never seen .....naaaah, it takes to much of  my time... never mind. Good luck to all who have this....."coin".


Very slow syncing is a known problem with the CLAM client... unfortunately no one has figured out why, yet. If your client stays open everything works fine, but if you leave things for a few days, the debug log gets filled with errors like "ORPHAN BLOCK 751" and "already have block..."

Just a warning, do NOT use Yobit for CLAM (or anything, really)

I found the workaround to set the maxconnections=1 - then you will be receiving blocks only from one source and there will be no competition/false orphans (my guess is the client is receiving the syncing blocks from the past AND the current blocks together)

(i) Trading Clams is not supported on Coinbase

They are just showing the Clam price.

Let's stop the rumor mill. Why would Poloniex delist the excellent Clam coin?   Sounds ridiculous.  It's a great coin, solid features, support and community, generates significant volume for them, and they are the primary trading site, making a tidy profit.

It appears there may be confusion in regards their notice at
  https://medium.com/circle-trader/overview-of-btc-margin-lending-pool-losses-a2f0905aaa56

where they will stop **margin** trading, for a while, on Clams, Factom, BTS, MAID, out of market depth considerations.

That has nothing to do with Clams trading in general and overall listing status.

It fact, it's a great move, they should never have allowed in the first place.  The margin pool on Clams was a terrible vulnerability, and is exactly a fault cause of the recent price drop, and possibly the prior one too.  It's very good for Clams that Poloniex remove exposure to the margin pool.


Exactly.
Only afraid I have is, that they will delist it as it would be cheaper than fix it. (Current state of screwed withdrawals)
But there is no official statement about delisting.

Stop spreading FUD.

so no here reading this has a friend or connection to any exchanges?

if you do, they to get clam  listed.

try to do this before July 8th, otherwise knowhas dark monday






13 days till maybe clam being delisted and clam is on no more exchanges

I cant find any official statement to support this claim.

wonder if anyone is gonna pump this to $30

That would be great!
But the price is held up by the very suspicious buy-wall. It pushed the price up, but it stopped at the 0.00195. Also it can disappear at any time.

BTW, anyone an idea what could be the motivation behind putting > 500 BTC into a buy order wall on a single exchange trading that coin (according to coinmarketcap poloniex has 99.92 % of the volume)? And the sell side of the orderbook is basically empty.
I kept track of this for a week or so, and the wall is moved to higher prices by about 0.5 USD per day. Even if it's a pump'n'dump, this person might have difficulties to re-sell his gained coins. I really do not get, why people do such a thing o_o. Any ideas?


This coin is owned by Poloniex itself, it's a pure scam since it's traded on Margin trading they are playing against shorts.
It's a pure casino, don't touch this coin it's a pure gambling.

I agree its pure gambling, but disagree with the poloniex conspiracy, because the main purpose of the coin is to be gambled on just-dice.com.
Also the poloniex has lots of issues with the Clam deposit and withdrawal (takes hours to deposit, causes errors when withdrawing) - its not what you would expect if they would have some secret plan with it.

Hello! Changelly is here:) In case you are in touch with CLAM representatives, please forward this form for listing: https://goo.gl/forms/cVlP8mRq8033pIDA3. Our team will familiarize with the info and contact CLAM community once we decide to partner. Thanks!


Looks like scam.

Form is not hosted at the Changelly website, using generic google drive storage, typos...
Probably would require "deposit" for listing and run away.

They require 400 confirmations to be "safe" and they just had a sketchy hack. Like hippie said, but failed to mention.  https://www.chepicap.com/en/news/8945/cryptopia-reopening-of-deposits-withdrawals-sees-flood-of-new-volume.html  (Sees a flood of traffic... right!!!!!!!! lol god)  

If you want to use a market that forces your privacy, https://poloniex.com/exchange#btc_clam is the only "real" market atm for CLAMS.  Polo has lots of problems going in and out that can cause you to have serious wait times. "They" have given them the fix and are hopefully waiting for them to implement them.


It has been 11 days now since I made withdraw of CLAM from Poloniex
So, something is not right.

My personal recent experience, the clam deposit I made took 6 hours or so but the btc withdrawal was near instant. Not exactly what you are referring to but proof enough that at least some of their related systems are working.

Polo recent has gotten worse again sadly.

I've got a number of CLAM withdraws with txid's that aren't "real".  I don't even know how to explain it tbh.  It's weird.

Same here - Open a ticket "Transaction not broadcasted"
Good thing is, that every case was solved by the the support.

Just happened to check coinmarketcap.com... Why is the CLAM-price at Yobit.net so much lower than on Poloniex?

https://yobit.net/en/trade/CLAM/BTC

vs

https://poloniex.com/exchange#btc_clam

I mean, someone could just buy them all and sell at Poloniex. Is there some problem with the block chain or any of the exchanges?

I think somebody mentioned it earlier that yobit is SCAM. I have no personal experience so I am following the wisdom of the crowd - I assume there are issues with the deposit/withdrawal so you cant arbitrage effectively.

I have never had any problems with withdrawal/deposit on Yobit. However, never tried out Poloniex.

Poloniex is reliable in the terms they don't run away with your money, you need to have some verification - but is currently having a bit troubles with depositing/withdrawing clams.
Deposit takes 5-10 hours to appear and withdrawals sometime end up in error state - requires contacting the support to get the coins back to the account. I got in the loop, when 3-4 following withdrawals were error.

Hi, I uploaded compressed content .clam (except my wallet and clam.conf) - the last block included is height=2535010 date=05/02/19 06:10:40
http://46.36.39.117:9080/  -  its my test VM, if it will work well, I'll do proper domain, interface and automatic daily update.

Its done from the linux (Ubuntu) client and I tested it with separate linux and it seems works. I'll try to test it with windows and raspberry client soon but if you want to betatest, feel free to download it.

Linux instructions: Just unzip everything into the .clam folder.
Windows instructions: To be determined

Thanks, Faust! Thats a very nice work!

But the problem with this is that nobody can be sure that your copy of the blockchain was not tampered and/or is a fork of the original chain. So before everyone download it, please wait for some confirmations from the developers that this copy is genuine, or you might lose your coins.

Another problem with this is that nobody can be sure that there is no backdoor or any malicious code in the zip that could steal wallet.dat data.

And please dont take this as a insult, Faust: Its because in the crypto community you better be safe than sorry. So your work is very appreciated, but you need to make a reputation before releasing this type of files.

Did you downloaded the ZIP from Faust? You can check if the blockchain is correct by following these steps:

1 - Put the zipped files in the CLAM folder without your wallet.dat, and preferably in a virtual machine without any sensitive data.

2 - Open the clam daemon, and wait for it to finish sync. You can speed the synchronization process by using

Code:
maxorphanblocks=10000

on clam.conf file

3 - type

Code:
getbestblockhash

to get the latest block hash

4 - Access http://khashier.com and click on the latest block number (link in blue)

The hash presented in khashier sould be the same you got in your clam client. This does not guarantee that the files in the zip arent malicious, tough.


Suggestion to Faust: Creating a torrent might be a better idea to serve these files.


For everyone having problems syncing: Please use the new beta client, it syncs much faster. It can be found here:
https://github.com/nochowderforyou/clams/tree/2.1.0

Thanks for the highlighting the issues - never trust anyone online (the same applies for the 2.1.0 new beta client*). When I was downloading zipped PIVX blockchain I did basically the same you mentioned (check last block against public blockchain explorer)

And its better that someone else point it out as the original publisher could post misleading information how to verify...

I just can't figure out how having forked chain could lead to loosing coin - as they will stay where they are on the original chain. And there are no executable binary in the .clam that could be tampered.

Gaining reputation is hard.

man i gave up afer ~19 days , trying to sync (2kb/s),
but even with the bootstrap its painfully slow at 3kb/s (import ~3000 0000 0000 kb ...)
and  thats not all,
i gave up because biggest thing which sucks very hard is that client stops after a random amount of time to work(import/load)

i have enough, i accepted 3/kb/s , but 50mb per day - screw this. :-(
maybe fix this client , others crypto coin chains load up to 1 GB per hour (with less connections)

man its crazy how fkin slow this is, i downloaded the 3GB bootstrap,
imports 0,5mB per second which in theory takes 4,5 days or more ?

i get 12 connections but what is wrong with this client is it programmed in javascript?
i testet it on 2 different Pcs.

i suggest instead of a bootstrap upload a user directory(without wallet.dat)
so the import doesnt tak 5 days. The hole point of a download is that its faster, but the bootstrap itsn't much.


I am planning to rent VPS and do so, maybe I'll run my own Clam blockchain explorer. Please look at my previous comments, I was asking if its a good idea to do it, but it doesn't caught much attention.

I have downloaded the bootstrap and my clam wallet is now up to date.
But when I search the wallet address:
xJCN6a8jiBj1hEEdnmJf43UJUGzwn7Fd3W
on https://prohashing.com/explorer/Clam/
it says "No block hash, transaction hash, block number, or wallet address was found. "

I have also created a new address, same response.
Tried sending some test coin from Poloniex, still pending.



Hi, that is normal for any cryptocurrency - when there is no transactions, the address is "something like invisible" for the explorers. Its because the amount of possible addresses is so huge, it would be impossible to add all of them. But some explorers can at least validate, that the address is valid.

The Poloniex withdrawal is just painfully slow - you have to wait.

I sent you some*, so you don't need to wait for your address appear in the blockchain explorer - use it wisely for exploring with the Clam - welcome and enjoy!

*Sorry for the typo in the Clamspeech :-)

Hi,
I consider running Clamcoin service providing daily blockchain snapshots because its the quickest way to get new wallet synchronized. I had to recently re-synchronize my node and it was slow and painful process. So I can imagine that it could be helpful for a Clam newcomer to get the wallet ready in shorter time.

PROS
+ Wallet is synchronized immediately after downloading/unzipping snapshot

CONS
- You have to trust that the snapshot is providing correct blockchain

So my question is
- Do you guys think its generally good idea?
- Is it actually running somewhere already and I just missed its existence?
- Are there any drawbacks I haven't considered?

Thanks

Guys, can I get some feedback? Do you think its a good idea?

Its a bit strange, as the bootstrap from the link should have 2467400 blocks.

Anyway - after finishing bootstrap it should start syncing from the network.


Those errors probably are from the network sync - I get a bunch of the same "already have block" errors when syncing any substantial amount (for example, after the client being shut down for a month). For some reason, it appears the client is asking multiple peers for the same block, or range of blocks, even though it already has them.

For example, my debug.log contains this 38 times:

ERROR: ProcessBlock() : already have block (orphan) 2035698dc4b0cf0617085d8448442a2ab6b3e63caa4ebcd01316186efe4736f7

Doing some quick counting, there are over 4000 different blocks which arrived 5+ times during the one sync.

I noticed similar "already have block (orphan)" when I was syncing last time. I think its because its getting same block from different nodes at different time. I "solved" it by reducing number of connections in clam.conf
maxconnections=1

When the clam is connected to the only one other node, this orphans completely stopped appearing.

If someone could tell me how to sync the wallet that would be great.

Download a bootstrap.
https://bitcointalk.org/index.php?topic=623147.msg9772191#msg9772191

Also for syncing I noticed, that having multiple connection to other nodes creates "ERROR: ProcessBlock() : already have block  XYZ" and trigger lookups for Orphan blocks which slows down the synchronisation.
I usually reduce the maximum connections while synchronizing to have only one source and not get ERRORs and ORPAHNS.
Set
maxconnections=1
in clam.conf and restart the client

Note: There is slight chance you get connected to some malicious node and you download forked chain, but I never encountered that. Plus after you finish syncing you can check the hash of the last block with some public clam block explorer.

Note 2: The sync takes some time to finish, depends on the CPU of you machine (it basically verifies whole chain on the fly) - it can take few days (when I tried to sync using Raspberry Pi in January, it took a week to fully sync)

I have downloaded the bootstrap and copied it.
But my wallet stops importing at block 1,775,795 ( 1 year and 12 week (s) behind ). The " importing blocks " has also disappear from my wallet , What should I do ?

Have you tried to restart the client?
Do you have enough space on your disk?
Do you see any ERRORs in the debug.log?

I think I have enough space.
this is on debug file

And I just noticed that name of "bootstrap.dat " file changed to "bootstrap.dat.old"

Hi,
 "bootstrap.dat.old" means, that the bootstrap was fully processed.
"already have block" means that the Clam tries import block from bootstrap, but its already in the DB (maybe from the previous run).

Its a bit strange, as the bootstrap from the link should have 2467400 blocks.

Anyway - after finishing bootstrap it should start syncing from the network.
Do you have at least one connection?

Another Poloniex withdrawal - another withdrawal ERROR   Angry
I am starting thinking that the issue is in the high amount of the withdrawal - too many inputs in transaction leading into the error.
I'll try smaller amount next time and let you know it it helps. (After the support credit the coins back)

EDIT: Coins are back, it took only 7 hours now. The support is getting better. :-)
