[ANN] Fastcoin - FST - The Fastest coin so far in the market - is launched!!

[EdithS]

I can't get the blockchain to sync either.  I'm a bit concerned because my past experience with livecoin isn't good when coins have issues.  I feel like things were going great with FST up until the "big announcement".  Things like a functioning desktop wallet that everyone can use without hours asking questions and a blockchain explorer that works are miss.  I'm starting to get the feeling that if we pulled back the curtain on this coin the blockchain wouldn't look particularly healthy.  I'm certainly not an expert but these problems persist and that is become concerning.  Hopefully I'm wrong....

Hi Koover,

Did you try installing the 8.7.2 wallet work around as they suggested?  You can download that wallet here...

Its working great for me, I bought more coins today and was able to send coins from the exchange to my wallet with no issue.

[LiveCoin]

Dear clients, deposits/withdrawals will be available soon. You don't have to worry, all of your FST funds are in safe. The root of issue with FST lays in scam transaction which was send from Cryptopia to Livecoin. This transaction have positive confirmations and no block hash, what is impossible. That is why we decided that FST blockchain have some issues, but later on the developers explained us that block explorer used as official on Coinmarketcap is not an official one and displays a lot of incorrect data.

So, we're waiting a link to official block explorer. We also waiting when the developers will contact Cryptopia regarding this scam transaction and let us know how Cryptopia managed to send this transaction into FST network.

Is there a working block explorer?  Where can I find it?

No it's full on inaccurancies: just scroll down and see that they're accounting all orphans.
That is, todays we're at 2 FST per block. You can see that somewhere there are double #blocks... one block with 2 FST, the other one (same #block) with 50-100 or more FST.
And in fact the counter shows 180+Mils (incorrect).
So also the 100rich list is wrong.

However is useful to keep track of the current #block (you can check it with the wallet as well).
For your info, the DevTeam is working on wholly owned hosted bkchain explorer.
Maybe the DevTeam will soon release kind of timing for this dedicated explorer.

txid? It almost sounds like your client isn't seeing it, and you're just going off the bogus information on the broken block explorer. Does the tx actually exist in the blockchain?

I agree.  Why is Livecoin.net using a block explorer to validate transactions?  The "gettransaction" RPC command will tell you or the exchange software how many confirmations that a transaction has.  Tracking confirmations is very important for exchanges as they all have different requirements for how many are needed before you can sell or transfer those coins.

The transaction in question is interesting, assuming anything about it is real.  It has 1165 inputs to add up to 134781 FST.  The size of the transaction from this block explorer is about 176,000 bytes.  This reminds me of the stuck transactions from Cryptsy which had rather large transaction sizes.  Transactions themselves do not have timestamps, but the date on the block explorer is Dec 1969 which is 0 in unix time.  This might be because this was in the mempool of the blockexplorer and it was never confirmed.  This transaction never would get into my mempool on 10.2.2 for reasons below.

We know from previous messages on this board that the different versions of fastcoin circulating have different rules for transaction sizes.  Cryptopia is using 0.8.7.2 (https://www.cryptopia.co.nz/CoinInfo/?coin=FST).  And from the source code:  https://github.com/fastcoinproject/fastcoin/blob/fastcoin-8.7.2/src/main.h

Code:

/** The maximum allowed size for a serialized block, in bytes (network rule) */
static const unsigned int MAX_BLOCK_SIZE = 1000000;                      // 1000KB block hard limit
/** The maximum size for mined blocks */
static const unsigned int MAX_BLOCK_SIZE_GEN = MAX_BLOCK_SIZE/2;         // 250KB  block soft limit
/** The maximum size for transactions we're willing to relay/mine */
static const unsigned int MAX_STANDARD_TX_SIZE = MAX_BLOCK_SIZE_GEN/2.5; // 100KB tx size limit

200,000 byte transaction sizes are valid, so the above transaction is valid on that basis.  The comment says 100KB, but that is incorrect (1 million divided by 2 and then by 2.5 is 200,000).

https://github.com/fastcoinproject/fastcoin/blob/10.2.2/src/main.h

Code:

/** The maximum size for transactions we're willing to relay/mine */
static const unsigned int MAX_STANDARD_TX_SIZE = 100000;

And version 10.2.2 has 100,000 size limits.

In my experience, anything over 10,000 bytes took a long time to confirm and some were never confirmed.  From this I suspect the miners are using 10.2.2 or very large transaction sizes cannot be handled for other reasons.

This particular transaction getting stuck is not new, but it is rare as most people don't have thousands of small transactions in their wallets.

Ok, thanks. I downloaded this version of the wallet. At me all was synchronized.

Hello! already one year has passed, how my transaction can not up to me to walk. what do I do? there 85821.94807831 FST

Good morning everyone,

We want to take the time to post our response we have on this issue from our SLACK channel on this forum as well for any parties interested to see updates to this issue.  We have copied and pasted it below....

"Update to Livecoin issue:  Our team has finally reached Livecoin support on this issue.  It appears the root cause of the problem is a faulty Block Explorer http://fst.blockexp.info/ was being referenced by Livecoin for certain transactions.  Furthermore, this Block Explorer was picked up by Coin Market Cap as one of our official sources for reference.  We are not sure who communicated this to Coin Market Cap, however it appears someone from the Crypto Community took it upon themselves to ask Coin Market Cap to post the above mentioned block Explorer as one of our official sources.  Please note, this block Explorer is NOT ours, we have tried to contact the owner of this Block Explorer and they have not responded.  We have audited this Block Explorer and have found numerous inn-ac-curacies with it.  It appears it may be including orphaned blocks into its calculations, we are not 100% sure as we do not have direct access to its source code.  We have also sent an email to Coin Market Cap to remove the link they currently have pointing to this Block Explorer and are awaiting their response."

If the owner of this Block Explorer happens to read this thread, please DM myself or Cheetahx ASAP as we may need your assistance to help resolve the current issue with Livecoin.

Thank you to community members in this forum that have done their best to direct others to our SLACK channel for updates to this issue.  Yes the SLACK channel appears to be a better place to keep current on these issues.  The best way to sign up to that channel is via the follwoing link....

Timestamp: 31st Dec 1969?
To me it looks a cheat attempt.

Unix time is expressed as the number of seconds since midnight UTC on January 1st 1970. So 1st Jan 1970 00:00 UTC is 0.

31st Dec 1969 18:00 would be 'unix 0', adjusted for timezone (UTC-6)

It's most likely a reporting error on the block explorer. I doubt any coin client would accept a transaction (or block) with a calculated timestamp from nearly 50 years ago. Or a timestamp value of 0.

Others have mentioned that this block explorer is unreliable.

Cryptopia and Livecoin, both of which might be using 0.8.7.2 software, need to -rescan or perhaps turn off and turn back on again their fastcoin clients/daemons.  This should wipe their mempools of this unconfirmed transaction.  They might need to adjust their database system to remove records that the transaction was sent or do something to return the balance back to the customer.

Thank you Almightruler,

You are correct, we also feel it is a reporting error on the block explorer.  We have reached out to the owner of this Block Explorer and asked him/her to assist us in verifying this with us.

Thank you Stouse49,

Yes we believe you are also correct here, the exchange should -rescan or turn off and turn back on again their fastcoin clients/daemons to flush this out of their mempools.

We have a case open with Livecoin on this issue and we are waiting for them to get back to us and to also confirm that they have taken this action on their end.

FST scammmm?

Hello Saman02,

Please note, there is NO FST scam occurring here.  What seems to be the problem is what was mentioned above.  These types of problems are also indicative to Bitcoin and many Cryptocurrencies.  We have a case open with Livecoin on this and are waiting for them to get back to us with additional information.  Sending and receiving from Cryptopia to our personal FST wallets continue without issue.

Hello.

Cryptopia and Livecoin, both of which might be using 0.8.7.2 software, need to -rescan or perhaps turn off and turn back on again their fastcoin clients/daemons.  This should wipe their mempools of this unconfirmed transaction.  They might need to adjust their database system to remove records that the transaction was sent or do something to return the balance back to the customer.

Livecoin don't need to rescan because them didn't sent this invalid transaction. Only Cryptopia need to do that.

About this transaction.

1. Time not correct. 31st Dec 1969 18:00:00 LOL
2. Confirmations. We see that this transaction have 10475685 confirmations but this coin mined only 10475692 blocks.. So this transaction sent 3 year old?
3. Block, what block number of this transaction? Where Block Hash?

Please note, there is NO FST scam occurring here.  What seems to be the problem is what was mentioned above.  These types of problems are also indicative to Bitcoin and many Cryptocurrencies.  We have a case open with Livecoin on this and are waiting for them to get back to us with additional information.  Sending and receiving from Cryptopia to our personal FST wallets continue without issue.

Dev.. What you want from livecoin? This exchange can't receive invalid transaction without valid txid.. Where is working block explorer that don't lie? How i see the problem not with livecoin.

The problem with you (devs) or sender (cryptopia). So if you or cryptopia don't have problems, please send me VALID txid for this transaction with link to correct working block explorer. I will check this txid in my node and block explorer.

Thanks.
