A Small Crypto Coin is Developing a Private Proof-of-Stake
Spectre wants to authenticate Blockchain transactions
A little known ongoing project about cryptocurrency called Spectre with a market capitalisation of $5.7 million may come soon under the radar along with other cryptocurrencies present in the market. Spectre’s has two tokens known as ‘Xspec’ and ‘Spectre’ which fall under the 500s in the Coinmarket’s cryptocurrency ranking.
There are a bunch of alternative proof-of-stake systems that have already accumulated a large market capitalisation with the help of major investors. Notably, some such proof-of-stake systems are EOS, Tezos, NEO, and TRON.
Spectre’s Proposition
According to Mandica, the founder of Spectre, there lies the biggest issue with the current proof-of-stakes as they have a privacy problem within their systems.
“All the UTXOs [unspent transaction outputs] spent to generate staking transactions are traceable on the blockchain, all the staking transactions can be linked, and your balances are visible to anyone who knows how to analyse the blockchain,” told Mandica.
Proof-of-stake appoints the task of authenticating Blockchain transactions to representatives present within the network. The design of the system is constructed such that even if the representative does not provide its identity, all the transactions whether they are staked or not can be traced within the blockchain. Moreover, someone who knows the process to operate the system can see all users’ balances.
Mandica claims that they are currently working on a range of tools to make staking private so that the users’ balances are not traceable by anyone within the blockchain system. Though the technology is not ready yet, it will be introduced soon enough to allow the users to keep their entire balances and transactions anonymous such that can’t be traced back to them. Furthermore, the users can even get more anonymous coins by staking their wallets.
According to the founder of Spectre, “This is a unique proposition, and no other cryptocurrency, as far as I know, has a system to stake anonymous coins and generate fresh anonymous coins.”
The Process
Though the project has kept the working process details away from public knowledge, they promised to reveal it soon. However, as of now, the only information available is that the system is based on Monero’s ring signature technology. It is worth mentioning here that the ring signatures allow delegates to sign a transaction while hiding the essential details which has been used to approve the transaction. Though the ring signature technology is not completely anonymous as the nodes are still present to view the operation, Spectre’s team is currently working on the solution for it.
The solution will have the concept of one-time vital pairs and stealth address technology similar to the idea behind the Tor project.
According to Mandica “The ‘anonymous’ coins are created using stealth address technology and one-time key pairs, and [they] reside on the blockchain as un-linkable UTXOs that can only be spent by proving ownership through the use of ring signatures and key-images based on the Cryptonote protocol.”
Mandica also explained that the proof-of-stake algorithm is designed on the advantage of creating new tokens without leaving a trail of the previous history to create an anonymous path to hide the transactions.

Great post. I was checking constantly this blog and I’m impressed! Extremely helpful information particularly the last part 🙂 I care for such info much. I was looking for this particular information for a long time. Thank you and good luck.
Great site! I am loving it!! Will come back again. I am taking your feeds also.
Thanks for some other informative site. The place else may just I get that type of information written in such a perfect approach? I have a undertaking that I am simply now operating on, and I’ve been at the look out for such info.
Throughout the grand pattern of things you actually receive a B+ for effort. Where exactly you confused everybody was in all the facts. As as the maxim goes, details make or break the argument.. And that couldn’t be much more accurate here. Having said that, permit me reveal to you what did work. The authoring is actually incredibly engaging and that is probably why I am taking an effort in order to opine. I do not make it a regular habit of doing that. 2nd, while I can easily notice the jumps in logic you come up with, I am not sure of exactly how you appear to connect the points which in turn produce your final result. For now I will subscribe to your issue but hope in the near future you actually connect the facts better.
I like what you guys are up too. Such clever work and reporting! Keep up the excellent works guys I have incorporated you guys to my blogroll. I think it’ll improve the value of my website 🙂
I truly appreciate this post. I¦ve been looking everywhere for this! Thank goodness I found it on Bing. You’ve made my day! Thx again
It’s actually a great and helpful piece of info. I’m glad that you shared this useful info with us. Please keep us informed like this. Thanks for sharing.
Hi there just wanted to give you a quick heads up and let you know a few of the pictures aren’t loading properly. I’m not sure why but I think its a linking issue. I’ve tried it in two different internet browsers and both show the same results.
When I originally commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is added I get several emails with the same comment. Is there any way you can remove me from that service? Thanks a lot!
Perfectly pent content, Really enjoyed looking at.
