★★★ PandaCoin [PND] ★★★ 2021 Network Update

[pandacoin-official]

This error indicates that your copy of the blockchain has been corrupted through either issues during the previous runtime, or bad storage.
Since you appear to be using a custom version of berkely db I would assume that it is caused by the former.

To avoid having to redownload and reevaluate the entire chain one could copy a valid state of the chain and simply copy that back, should this error surface again.

Alright guys,

Got another bug report to work on this morning.

This same problem also happened with the earlier version of Panda I was running, before you switched me to this latest version.

1.  I open PandaBank.
2.  The loading screen says Loading Block Index...
3.  Switch to web browser (or any other app) to do something else while Panda is loading.
4.  A while later later, PandaCoin-Qt quits unexpectedly
5.  A quick read of the crash report indicates...
Crashed Thread:        0  Dispatch queue: com.apple.main-thread

Exception Type:        EXC_CRASH (SIGABRT)
Exception Codes:       0x0000000000000000, 0x0000000000000000
Exception Note:        EXC_CORPSE_NOTIFY

Application Specific Information:
Assertion failed: (pindex->pprev || pindex->GetBlockHash() == (!fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet)), function GetStakeModifierChecksum, file src/kernel.cpp, line 391.
...
6. Attempt to reopen PandaBank
7. Keep PandaBank active without switching to any other app... wait forever (we never progress beyond the loading screen which says Loading Block Index).
8.  Finally get tired of waiting and switch to another app to do something while waiting...
9.  When switching apps, the loading screen is hidden until you go back to PandaBank, and when it is hidden, an error window is revealed to have been behind it!  Viola.
10.  The error screen has an exclamation point on a stop sign and says, Error loading blkindex.dat.
11.  Click "OK".
12.  PandaBank closes with clicking "OK"
13.  Navigate to to ~/Library/Application\ Support/Pandacoin/ and delete all its contents except for wallet.dat
14.  Empty the Trash
15.  Open PandaBank
16.  It works.
17.  Now it will take a long time to get things back to normal, through syncing.

I attempted to make a quick video of this to help you troubleshoot.  https://youtu.be/HjUSjLIGuu0  Thanks for everything

Wow very detailed escalation report!, please hang in there.  Very nice video work btw!
This may be due to how I had you install Berkely. Did the trouble begin after you downloaded our snapshot?  Is it happening now if you close and re-open PandaBank?  It might be a good idea to close PandaBank and brew uninstall berkeley-db4 and then brew install berkeley-db@4. I had a typo the first time I asked you to install it. I second guessed myself and diverged from our recommended version, the  berkeley-db@4 is what we are using on ours.

Who's giving away Pandacoin paper wallets for Xmas?

I'm not buying anything for anyone this Xmas. Instead everyone is getting a Pandacoin paper wallet.  



Will print up a fancy envelope to put them in and keep the private keys safe from being snapped in a selfie.

Anyone else done this before? What do you recommend?

Setup and print the wallet first then fund the account. Maybe keep a backup of the private key in case they loose it. I'm sure people will loose them.

Thanks jommy,

I followed your recommendation and didn't have any different result.  I do a little web development, but I wish I were familiar with XCode, swift, qt, etc; I'd dive right in and help.

Panda should somehow try to jump on the PoS bandwagon. Maybe with something like "The Dogecoin of PoS" or so (because PND was once a clone of Dogecoin and then switched to PoS).

BTW what's PND's take on Atomic Swaps that are just going hot right now?

Atomic swaps, or atomic cross-chain trading, is the exchange of one cryptocurrency to another cryptocurrency, without the need to trust a third-party. A relatively new piece of technology, atomic cross-chain trading is looking to revolutionize the way in which users transact with each other. For example, if Alice owned 5 Bitcoins but instead wanted 100 Litecoins, she would have to go through an exchange, i.e. a third-party. However, with atomic swaps, if Bob owned 100 Litecoins but instead wanted 5 Bitcoins, then Bob and Alice could make a trade. In order to prevent, for example, Alice accepting Bob’s 100 Litecoins but then failing to send over her 5 Bitcoins, atomic swaps utilizes what is known as hash time-locked contracts (HTLCs).

https://www.cryptocompare.com/coins/guides/what-are-atomic-swaps/

It's needed to get on decentralized exchanges like BarterDex.

http://barterdex.supernet.org/

Decentralized exchanges will be the next big thing. They have a few benefits in contrast to traditional centralized exchanges by being p2p and thus more safe against hacks and theft, market power by delisting coins and governmental seizure and similar attacks.

Atomic Swaps just need some BTC features enabled on the coins and off you go.

I think coins will become irrelevant in the future if they don't support decentralized exchanges.

That is a great idea! 

Seriously, especially if you have younger relatives or friends this / BTC in a paperwallet might be a perfect gift.

I do not understand ..Pandacoin.
Pandacoin.Circulating Supply 32,514,916,898 PND   $0,000048 USD (-57.77%) Market Cap $1 565 392 USD
Cardano (ADA) Total Supply  31,112,483,745 ADA    $0,220579 USD (4.88%)   Market Cap  $5 718 967 292 USD

Am expecting lots and lots of dumping along the way though. Not just from normal folk  wh hold large bags from 4years ago but also from Amdoge and cronies who will be holding seriously large sacks.

There are many lost wallets and un-recoverable Pandacoins, we have always been an ideal cryptocurrency to learn with, and over the years mistakes are made.  Many exchanges have had trouble and disappeared with lots of Pandacoin, computers crash without proper backups etc so many large wallets from the old days will never be active again so it is hard to tell our true distribution or our circulating supply.

https://steemit.com/pandacoin/@dp1011/staking-pandacoin-pnd-for-nostalgia-maybe-profit

I agree, but you know what? Let them dump. When the price goes beyond what they sold it for, they will regret it BIG time, especially if we can truly bring a new community together to make this loved coin last. There is no reason why this coin can't be as successful if not more successful than DOGE.

Guys, is Yobit safe to buy some PND? I'm careful, because Yobit does host some old chains of coins and things like that. But I have some BTC dust left on Yobit and would like to buy PND, I like the fact people are working hard to revive this coin again

That just shows how undervalued PND currently is. Development is picking up again so there is not a better time to jump on board than now..

I bought some millions at 1 Satoshi and now selling price is under 0.01 DOGE , I expected this coin reach at least to 5 Satoshi.

I have an error to report, I am trying to get the latest version of the pandabank wallet running, and it fails to install on my mac.

Jommy99 - I followed the download link for Mac you recently posted when helping jdhadwin on Dec 13th.

I backed up my wallet.dat file (I actually duplicated the entire folder in my /Library/Application Support folder), and deleted the pandacoin-qt file in the /Applications folder.

I then went to run the pandacoin-standalone-pkg file, and it got through the first few steps, where it asked for my pass and went to 'Installation' step, then it says:

Installation Failed
The installer encountered an error that caused the installation to fail. Contact the manufacturer for assistance.

I then decided to make sure my OS was fully up to date, so I ran the installer and updated my OS to the latest High Sierra  10.13.2. (running on a Macbook Pro Retina circa 2013.

I tried the installer again, and got the same error.

Anyone have any  suggestions on what to do next?  Many thanks.

I've been trading on yobit for a while now, never had a single issue with them, never had to contact support so I'd say it's safe.

Thanks, it's more like sometimes it looks like they use a fake token instead of the real coin and when doing a withdraw you are on another or non-existent chain xD

If you would like to try our latest Stand alone PandaBank for mac we can use your help too.  We seem to still be having a problem in some cases and are trying to understand better exactly what is happening.   In order to help make it easier to try and test we have combined the prerequisite libraries into this latest package http://files.cryptodepot.org/pandacoin-standalone.pkg  Thank you in advance for your assistance and feedback.

Hey, this coin is revived. There are 3000 coins in my wallet. I do not know if I can open my wallet. Which platform is currently trading?

So it seems this package is the same one I attempted to download from this link:
http://cryptodepot.org/downloads/ 

it's the same file size as the direct link above, and so it is giving the the same error upon installation.

It errors out so quickly, it's difficult to say at what stage, but I can see it's happening very shortly at 'Validating packages', then boom.  Errors out with a failure to install.

Is there a log file I can provide? If you tell me where to find it, I will submit this here.

Thanks so much for the help!

[jommy99]

Sorry about the delays and trouble with our latest mac PandaBank we are getting very close and have just updated the down loadable package again. The updated downloadfor now has the .pkg to install pandacoin-qt. To overcome a temporary problem we are still having,  it has a runme_first.sh and readme.html which will explain how to use runme_first.sh, hope this helps get some mac PandaBanks updated and or running properly.  We will continue to work on this to make it a simpler to use package asap.
