The cryptocurrency craze is in full swing yet again, and zcoins are one of the key new currencies to emerge after the blistering succcess of bitcoin.
The status and mainstream use of digital coins has changed dramatically, and become a new asset class of late.
I’m curious, so have jumped on board to investigate what its all about.
Below is a graphic tutorial about how to set up your zcoin wallet quickly and easily, without having to wait forever for it to sync.
Downloading and syncing a bitcoin wallet, which is gigabytes in size seemed too arduous and time consuming for an impatient guy with only a cursory interest in the subject, so I chose Zcoin.
You can download the wallet program for your OS of choice at the address above.
The catch is that it seems to take aeons to sync the wallet, by downloading the blockchain and processing it.
Apparently the start up process for your wallet can take days to weeks, through the size of the blockchain itself is only quite small, at around 187Mb! (at time of writing)
A couple hours after installation, less than 7% of the estimated transactions int he chain have been downloaded and processed.
I thought I’d be clever, avoid the pain, and download the entire blockchain file in its entirety off Znode.
Next step is to extract the zip file, and put the files in their requisite places for the zcoin wallet to pick up.
The unzipping of the Zcoin block chain file from Znode is a very quick operation, taking less than a couple minutes.
As promised, the zip folder contained the “blocks” and “chainstate” folders, which need to be dumped into the USER\Appdata\Roaming\zcoin folder on windows operating systems
A bit of copy pasting later, and I have imported the downloaded full blockchain files into the zcoin wallet to give it a head start.
I took the cautious approach, and just changed the names of the current folders with their 7% progress with a BAK suffix, so I can restore and go back to doing the sync the long way if the process doesn’t work.
Just for interest, at present, the zcoin blocks folder is 243MB on disk, and the chainstate folder is a teeny 11MB. Of course, as time goes on, this will blow out to huge sizes, as the coin is in its relative infancy.
Now, to see how long the processing and sync takes once this little boost has been added…
Looking at the stats on the system performance, depicted below; the CPU is banging away at a modest 21% load from loading the wallet.
It may be hanging, but we will see what comes from this in a few hours.
The situation looks fairly positive though, as the wallet.DAT file is being constantly written to during this process.
Posts on the zcoin website indicate that the reason it takes so long is verification of no double spends.
I’ve taken note of the time the verification began, and will update this post once I have a definitive loading time. A progress bar certainly would have been nice on the opening screen.
UPDATE! looks like it took about 5 hours to load the saved part of the blockchain… only thing, its now 8 hours behind, so will take quite a while to sync up again. (More hours!!)
