On behalf of the team behind Espers, the original one, I would like to wish you the best of luck on your project.
The team will still continue working on the project.

Exactly. That's just how crypto evolution works. Time will tell who can do better. If the chain is continued, or if at some point later a hard fork is done, nobody loses anything. If you can add more value to it on your own, go on!  Smiley Otherwise you might also consider joining the Cryptocoderz in developing the coin by submitting merge requests instead of cloning it.  Wink Generally working together to solve problems is more effective than two people solving the same problem independently.

It is confusing. The second dev team tries to overtake ESP. This includes overtaking the Network traffic with 51%. How this will be done or how it is planned at least, I don't know. Someone will have to Post anything on this case, either the new or the "old" Dev..

Err  Huh You cannot "take over a network" like that. The only thing that 51% attack allows is a double-spend attack. Blockchain is just a blockchain, you can make a hardfork without having 51% of the network coins available.

It's not difficult. Espers is Espers, Cryptocoderz is still Cryptocoderz. Someone threatened to create an Espers fork on the Twitter channel @EspersCommunity. That's it.

Cryptocoderz is still low on communication. So everyone has two options: 1) Wait or 2) Fork the coin (but please change the name then). Simple as that. You cannot make the current Espers chain or Cryptocoderz "go away" just like that. Some day, updates may come. Very simple.

This is very different from https://novaexchange.com/addnodes/XSPEC/

Which one is correct?

Sorry my bad! Must have been tired or something. It was for the wrong coin  Grin Thanks for pointing out.

Here is the node list for Spectre:

https://chainz.cryptoid.info/xspec/#!network

Click on node list. Generally, you can usually find the node list in the coin explorer of the respective coin.  Wink Or yes, some exchanges like Novaexchange also publish a node list.
544  Alternate cryptocurrencies / Altcoin Discussion / Re: Dash, Monero, Zcash Which Coins More Secure? on: September 21, 2017, 03:40:53 PM
i think you need to first clarify what is it exactly that you want!
you ask for "security" and then talk about transaction fees! well sometimes fees are the last thing you should care for when you are looking for "security" (whatever that means in your head.)

all of these have flaws. some small and ignorable and some are big enough to want to ignore the coin itself. i personally prefer Monero among these.

The only sensible answer so far. If you want to know which is the most "secure", you must define "security" first. Roll Eyes  Good luck with that. In terms of being free of bugs (so that your money is secure against devaluation), Bitcoin is probably the most secure, because it is fairly simple and has been tested for bugs and possible attacks extensively.

Is this coin use PoSv3 with reward 5% in year?

Yes.


What is different between PoSv3 and PoSv2?

Different versions of PoS developed by BlackCoin. See the whitepapers here:

V2: http://blackcoin.co/blackcoin-pos-protocol-v2-whitepaper.pdf
V3: https://bravenewcoin.com/assets/Whitepapers/Blackcoin-POS-3.pdf

The main difference is that the block reward is constant and no longer depends on the coin age.

I was wondering what the advantages of Spectre are compared to DeepOnion? Both coins seem to use the TOR network and are mainly focusing on stealth or at least privacy and private transactions. Why should I use XSPEC instead DeepOnion?

Take a look in the wiki here: http://coinwiki.info/en/SpectreCoin#DeepOnion

Ok Gandalf, thank you as always! But I still don't get what ring signatures and stealth addresses are, my guess is that this is for complete anonymity?

Yes, they are the technologies we use. There are whitepapers about them (google it), but I guess you're not interested in the technical aspects. Ring signatures are for sending anonymously, stealth addresses are for receiving anonymously. That's basically all it is about.

My dear friends, I have created a little FAQ for you that covers the most frequently asked questions here:

  • My balance is zero!
  • I can't sync!
  • How do I stake?

https://github.com/bitcoinx2/spectre/wiki/FAQ

Hope that helps, feedback is very welcome. I will extend this FAQ as more details become relevant, or more questions are raised.
549  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN]Spectrecoin[XSPEC] TOR+OBFS4, Ring Sig, Stealth! on: September 18, 2017, 10:06:51 PM
mhh my wallet is showing a zero balance altough i stake with my initial balance???
Restarted a few times now but all the same. Every time a zero balance.....
Anyone an idea what i can do?

Yes we are answering this question every day in #client_support, so please come to Slack so that dev can learn about possible problems and fix them! And you will get help as well.

where can I get node list?

https://www.espstats.net/nodes/

Sorry wrong thread  Grin

https://chainz.cryptoid.info/xspec/#!network

Hit on node list here.

Hello,
There "0 active connections to SpectreCoin network" popup in my wallet.
Should I use node list?

See my answer above. Come to slack, give your debug.log, also give it some time and yes you might try using a node list.

If you people share your problem in Slack that helps us to debug the problem, and avoid it in future versions.
552  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN]Spectrecoin[XSPEC] TOR+OBFS4, Ring Sig, Stealth! on: September 18, 2017, 09:21:17 AM
Hi guys, I just downloaded the new v1.3.3 Mac wallet. But I can't sync yet.
Who can help? Thank u.

Come to Slack to #client_support, share your debug.log. Also consider the wallet syncing guide in my signature. If you just downloaded the wallet, it should work. Maybe give it some time.
553  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN]Spectrecoin[XSPEC] TOR+OBFS4, Ring Sig, Stealth! on: September 17, 2017, 07:58:27 PM
@mandica, that makes sense. Thanks for clarifying!  Smiley Looking forward to the whitepaper. Using key-pairs for tokens sounds pretty exciting tbh. Cool

For the non-technical, this means that the ring signature system uses notes/bills of fixed value right now, just like cash. And each single note has its own public key attached. And you don't spend your balance by a wallet address, but by knowing the private keys for the "spectre tokens" you own. Plus, you actually rather own some bills from a bigger pool of cash that belongs to multiple people.  Wink Kind of like that.  Cheesy

Bitcoin problem - Address reuse
Bitcoin addresses were never meant to be used twice and the fact that they can is a ‘fluke’ in the system. There are 1.46 × 10^48 possible bitcoin addresses, which gives every person on Earth 2.05×10^38 different addresses to use if needs be. When addresses are reused, all other transactions performed by that address can be seen by examining the block chain. Address reuse also reduces the security of the bitcoins stored in those addresses. Transaction signing requires 256 bytes of random data (r­value) so that the private key cannot be reverse engineered. If the r­value is not truly random then the private key can be determined, which can be used to sign other transactions for that particular bitcoin address. This attack can be negated by not reusing addresses, as once a transaction is signed from a bitcoin address, it remains empty.
https://bitcoin.stackexchange.com/questions/25814/ecdsa%C2%ADsignature%C2%ADand%C2%ADthe%C2%ADz%C2%ADvalue

Solution in XSPEC – Dual Key Stealth Addresses
The basic principal with stealth addresses is to avoid address reuse. With a stealth address you can publish ONE stealth address and every payment made to that stealth address will appears as being received by a different ‘normal’ address.
http://sx.dyne.org/stealth.html

But this for receiving, right? While the first case for Bitcoin was about sending coins. In the linked article, it says:

Quote
ECDSA requires a random number for each signature. If this random number is ever used twice with the same private key it can be recovered.

So it's not about "truly random" or not, just not using the same random twice with the same key pair. So it would be enough to simply use a proper signature implementation that generates a new random number for each transaction. You should have fixed that anyway, because stealth addresses are not mandatory (yet). How do stealth addresses help on top of it then? Just for making the inputs unlinkable, as far as I know?


XSPEC takes this one step further by introducing anonymous ‘spectre tokens’ and introduce transactions signed by what is known as traceable ring-signatures. Do not let the word ‘traceable’ fool you, it simply means that once a transaction has been signed it will be impossible to use the same signature / ‘spectre token’ again.
https://eprint.iacr.org/2006/389.pdf

Wikipedia:
Quote
Linkable ring signatures
    [4] The property of linkability allows one to determine whether any two signatures have been produced by the same member (under the same private key). The identity of the signer is nevertheless preserved. One of the possible applications can be an offline e-cash system.
Traceable ring signature
    [5] In addition to the previous scheme the public key of the signer is revealed (if they issue more than one signatures under the same private key). An e-voting system can be implemented using this protocol.

So according to this, a linkable ring signature would be enough? It explicitly mentions the e-cash application. How does traceability help? It could even be used to deanonymize nodes by tricking them into doing the same signature twice.

Thanks for your work, but if you are making technical arguments they should be sound. Smiley

Regarding staking, why does "Est. Next Stake" changes? Does it go up when there are more coins staked in the network? I.e. when large holders stake on a laptop and they go online?

Yes. But you should know that the number shown is not a correct estimate in the current implementation. In reality it takes much longer because of Velocity bounds.
556  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN]Spectrecoin[XSPEC] TOR+OBFS4, Ring Sig, Stealth! on: September 17, 2017, 10:09:38 AM
Many people say that the value of this coin is underestimated, but I can not read it, do not understand it's technology, do not understand it's good, someone out to explain what?


Take a look at the wiki that is linked in the first post.


As far as I understand this coin, the devs want to equip it with a variety of proven anonymity technologies. Not sure if it's unique or practical in the end.

This guy got it!  Wink I'm not sure if it will stay unique, but I'm sure it will be practical, and that is the goal.

Hi,

I have a question. I started with wallet v1.3.0 on windows. Now I want to move to Mac.
I created a wallet backup the windows wallet v.1.3.0 (wallet.dat)

But I do not have an option to import it on wallet version 1.3.3 on my mac.

Thanks

Su

Ah yes...

We're back baby! Let the haters hate, let the ones who wanted us to sell out stuff their pillows with their money.

I say this because it seems like everyone thinks our return is a joke.

Well Anyway moving forward I've personally promised everyoine on twitter and discord to make progress over this comijng week as proof that we haven't left.

I'll leave it at that and let everyone just see for themselves.
We'll be in touch here again on Monday with the announcement of the upcoming upcoming update and roll it out as well. More to follow after that.

Wanted to finally thank anyone and everyone who still supports us and stuck through the "dark times" of silence the occurred while I had to figure out things personally in my own life.

Looking forward to the future with you all Smiley

Sorry but in my opinion, people here are right. Spectre already exists in this cryptosphere. And it also had an ICO. It would not be a good idea to start an ICO with the same name. I wouldn't go as far as claiming it to be a scam because of this. This entire cryptocurrency environment is a gray area anyway. It's all about innovation and profit...
560  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN]Spectrecoin[XSPEC] TOR+OBFS4, Ring Sig, Stealth! on: September 11, 2017, 09:52:46 PM
nvm my last question, already downloaded the wallet
can someone explain to me, how do i backup my data? and if i lose my computer, how do i access my previous wallet?

1. Copy the wallet.dat file to a safe place. This is usually enough.
2. To be extra safe: Go to the debug console, and use the exportprivkey command to extract your private keys. Store them in a text file; if necessary encrypt the text file.


Is there an uodate procedure? Or do injust install the new wallet? And drag over a .dat file?   Sorry fir the ignorance im new to spectre havent uodated a wallet before.

1. Backup your wallet.dat (see above)
2. Install the new wallet
3. Start the wallet.

You don't usually need to do anything, having a backup just in case something goes wrong.
