[ANN][XCN] Cryptonite | 1st mini-blockchain coin | M7 PoW | No Premine

[bitfreak!]

What pool software is used for M7 algo coins? I've been trying to find a stratum based server but haven't found anything, are the pool operators using a modified nomp they're keeping to themselves?

Unfortunately I don't think there is any open source pool software which supports the M7 algorithm, although I haven't looked in quite a while so I could be wrong.

[bitfreak!]

Good news, the explorer has been updated and the problem seems to be completely gone. The total sent and received values should now display the correct numbers and none of the transactions should be missing.

when I clicked on "resync" the wallet crashed

when I restarted the program it said it couldn't read a block

I removed block and data folder, as log files and restart the wallet... it just crash again

The first crash is a known bug, that resync button doesn't work. If you want to resynchronize you have to start your wallet with the -resync flag set. The second crash is probably because you didn't remove everything that needed to be removed. Just try using -resync and it should work.

wallet started and resyncing again

thanks!

Is the mini-blockchain approach unique to Cryptonite, or are other coins now using it? It looks very interesting.

Another question...

I've been brainstorming the past few months on a project that would involve the creation and deployment of a customized cryptocurrency for a specialized purpose. If the project were successful (and I've gotten it to the point where I have confidence it would be far superior to existing alternatives by most measurables), widespread adoption would result in extremely high transaction volumes (far beyond current bitcoin volumes). Thus my interest in the mini-blockchain approach.

However, I have a major concern/headache involving privacy. Inherent to my project would be the creation of accounts in the Account Tree that would be publicly identifiable. That is, people would typically set up an account (using client software that would include wallet functionality along with other features necessary to the project) that would include an "Alias" that would be visible in the Account Tree. The intent would be for the Alias to be publicly shared so that other users could easily transact using the alias rather than memorizing public keys.

(For reasons I won't get into, this is non-negotiable - I expect that 99.999% of users will want to create an alias, and even those who do not will need to share their public keys to use the system, allowing the public to identify the link between a person and their account.)

On the flip side, privacy is a must. It simply won't be acceptable to have everyone be able to see every time a user sends or receives a transaction (typically signifying an instance of the activity for which the project is designed), and who is at the other end of the transaction.

So I'm curious how the accounts are structured in the Account Tree in Cryptonite. Is each Account basically tied to a single public key? Are there any proved and efficient ways to shift funds in/out of such an account while obscuring their origin or destination? Conceivably, transaction volumes could be many billions/day if the project is successful, so the solution has to be compatible with that kind of scale.

In my earlier designs (prior to confronting the scalability problem and researching the mini-blockchain) I utilized 3rd party Nodes to obscure transfers and encourage off-blockchain transactions. (The use of Nodes is actually inherent in the project for other tasks which would be associated with each typical transaction.) So if some kind of anonymization based on 3rd party nodes is required they'd be available, but I wanted to avoid trusting 3rd parties for the financial stuff as far as possible, as a general principle.  

Clear as mud? I'll answer any questions as best I can to clarify.

TL/DR: I need anonymous transactions, while enabling people to openly share their public key (or alias tied to it in the Account Tree) with the world at large.

As far as I know there are no other MBC coins yet.

The intent would be for the Alias to be publicly shared so that other users could easily transact using the alias rather than memorizing public keys.

We did think about adding an alias system to Cryptonite, I already explained why we didn't implement it earlier in this thread: The main problem is that when you need to lookup an account in the account tree with only an alias you have to basically search through every account until you find it because you can't use the fast lookup properties of the trie structure. The same sort of issue also applies when registering an alias, other nodes basically have to check every other registered alias and make sure the alias in question hasn't already been registered

So I'm curious how the accounts are structured in the Account Tree in Cryptonite. Is each Account basically tied to a single public key?

The account tree uses a special type of radix trie structure, see our wiki for more info. Each account is only tied to one address, that is why I often use the words account and address interchangeably.

TL/DR: I need anonymous transactions, while enabling people to openly share their public key (or alias tied to it in the Account Tree) with the world at large.

You should find this interesting: Anonymity in the Mini-Blockchain scheme

Thanks for the feedback! Not as promising as I hoped, but it's still a step forward for my search for solutions.

well, I am with 7 days left since yesterday
I have 8 connections but  stuck at 427364 transactions

any ideas ?

Sounds like the 7 day bug. You'll need to resync again. I suggest using cryptonited instead of Qt to sync because it's not affected by that bug.

'd' running

OS 440504 NS 440505
Accepted block 440504
Accept block header

and goes on

till which block do I have to wait to use the qt version again ?

[bitfreak!]

till which block do I have to wait to use the qt version again ?

Until it's caught up with the latest block. Looks like it has already caught up, 440504 is close to the current block height.

up and running!!

sometimes the wallet get freezes for seconds

also take some time for the wallet to start when reading index

but, for sure these issues will be improved

ok now

I click on backup the wallet, the desktop message appears gloriously but... no .dat file is created

[bybitcoin]

I lost 4 million xcn for that ridiculous backup function in qt. Software. I created the backup, and sure of what the software does, saved the file in two different places. Now that I go to use and import it back, it shows a .dat.url file which is a simple text about nonsense.
So 4m xcn is gone, I know that I should have checked it before, but, to be honest, the pace of the reference software development has been ridiculous. I asked for the web-based wallet for several months, but nothing..
The main dev catia disappeared for several months, and all the core developments relies on him.
Of course bitfreak and catia have the right to choose how to spend their time, they have no obligation to continue developing xcn persistently, but what remains is a red flag  for anyone who is interested to invest in xcn long term.
No matter how innovative and ideal a coin idea might be, it will not last long if not supported by continuous persistent development, as an organic live existence.

ps: I know about the loss for a week now, backup has been saved in early April. I am not much angry about the 4m xcn loss.  As a veteran investor I've got much much more from the cryptocurrencies than what I lost here. But as one of the earliest supporters of this project, following it since it was only a paper 2 years ago, I have to criticise the naked facts.

So you don't have a copy of your original wallet file or your private keys? If you didn't delete the data folder your wallet file should still be there.

I've been putting off the web wallet because serializing and signing Cryptonite transactions in javascript is a bit beyond my ability. However now that catia is back he should be able to give me assistance on anything which confuses me, so I'll probably give it a go quite soon.

You are right of course, development on Cryptonite has been much slower than it really needs to be but not everything in life goes exactly to plan. Hopefully now that catia is back the core development can continue and some of the more serious bugs can be fixed.

I was on the run for a trip, just made the backup using the function button in the Qt. Software, and saved it in my flash card and my email (my wallet was encrypted of course). I just decided to delete the whole thing from my computer, and you know the end of my story..
I accept that I should have checked the files before archiving them, but on the hurry I somehow decided to trust the xcn software doing. My own fault, I admit, but my point for telling this story was to criticise the pace of progress.
I am glad that catia is back, and like you say, I hope that xcn gets the kind of progress pace that this promising coin deserves.

question:
what would be XCN transaction per second limit, let say: with 10M size block?
