1  Alternate cryptocurrencies / Altcoin Discussion / Boolberry V2: Efficient Compact Decentralized Anonymous Payments via Ring Sigs on: March 13, 2018, 04:53:44 PM
Boolberry V2: Efficient Compact Decentralized Anonymous Payments via Ring Signatures

Last year I started forming a group of like minded researchers, Chainmasons, to see how we could further improve the already efficient Boolberry variant of the Cryptonote protocol. When I refer to efficiency over other CN projects i.e. transaction verification, tps, scaling etc.

During this time our research efforts were split into two sections. The first was to either improve or replace the mining algorithm Wild Keccak [1]. Those results can be found in section 6 of our ePrint entitled "Itsuku: a Memory-Hardened Proof-of-Work Scheme." [2]

The second, to create the most efficient ring signature based privacy protocol. After 9 months of research and development we would like to share our findings with the rest of the academic community for peer review before ePrint publication. We believe that our system represents 3rd iteration of the Cryptonote protocol. For those that attended Financial Cryptography and Data Security 2018 [3] a few weeks ago, this is the same Boolberry v2 proposal presented at the end of the presentation. The slides from the conference are available in the link below.

Open Problems

Cryptonote achieves sender privacy through the use of Ring Signatures with 1/N ownership probability. The problem here is that since Cryptonote ring signatures are linear, as N grows in size so does the computational overhead. To our knowledge this problem has not been openly addressed by the academic community without introducing a trusted party as found in the RingCT 2.0 [4].

Open Solutions

Boolberry attempts to solves this through the use of a pruning system [5]. This has proven to be effective as seen in the size of Boolberry's blockchain size (3.8GB) vs Monero's (40GB) despite them being launched within weeks of each other. We go a step further by reducing ring signatures to a logarithmic size along with respective bulletproofs to introduce a compact confidential transaction scheme.

In our initial results, we've found that our system represents a 92.8% improvement at 100 ring members and 99.984% improvement at 1000 members in 1/N where N is number of members in the ring. Although we will need to update these figures as per the latest version.

Additionally, we also propose a newly designed technique for multi-signature transactions in the context of (linkable) ring signatures. Our presented DAP is planned as a future upgrade proposal for Boolberry upon further successive peer reviews.

2  Alternate cryptocurrencies / Altcoin Discussion / Boolberry Claims thread - Funds frozen by Bittrex and Poloniex on: January 23, 2018, 07:24:19 PM
Hello community,

This thread is for victims who've suffered at the hands of Bittrex and Poloniex for not only delisting Boolberry without explanation but more importantly for not allowing users to withdraw their funds. The first step here is to get a total amount of coins frozen on each exchange then afterwards pursue legal action against them to release holders' funds. There is also the possibility of seeking additional damages for pain and suffering caused by inability to access your own funds. Some holders in the Boolberry community have had withdrawal tickets open for almost a year now with no response from Poloniex. In addition, the liability of market manipulation for unexpectedly delisting the project without any explanation.

https://cointelegraph.com/news/poloniex-to-delist-17-altcoins-in-may-without-explanation

For those unaware, Boolberry was trading consistently with decent volume on Poloniex and Bittrex in the ranges between 100BTC and 2000BTC before delisting announcement occurred and crashed the market. So market liquidity is was not an issue for the delisting. There is also evidence of major sell offs (flash dumps) that happened about a week prior to the delisting announcement. While I'm not an attorney, I know from other cases that if proven that the sell off was from the exchanges that would also be considered a criminal offense (market manipulation) for knowingly taking advantage of buy support and the impact a delisting notice would have on the market.

https://www.reuters.com/article/legal-us-equifax-cyber-heitkamp/u-s-senator-on-equifax-hack-somebody-needs-to-go-to-jail-idUSKCN1BN261

=========================

If you have funds frozen on Poloniex and Bittrex please provide screenshot if possible of the amount frozen along with total amount in text. Once we have a full tally of coins frozen there we can then refer this thread to legal counsel where they can privately collect claim information from each victim. Unlike the Mt. Gox claim (https://www.mtgoxlegal.com/) both exchanges are still operational and have not declared bankruptcy yet.

Lastly, if you have funds frozen from other cryptocurrency projects or have suffered financial losses at the hands of unexpected and unwarranted delisting from either exchange I would suggest you start a thread for your currency's community.

Bittrex and Poloniex require transparency from their users to trade but do not provide any transparency to traders for their actions.
3  Alternate cryptocurrencies / Altcoin Discussion / Did John McAfee just lose credibility as security researcher? on: December 18, 2017, 08:05:16 AM
As we all noticed, John McAfee is promoting Verge as a legitmate cryptocurrency in the privacy vertical. I looked into their project and it took about 30 seconds to find out that all they offer is transmission privacy via TOR or i2p..

Bitcoin has offered TOR support since 2011/2012..

Anoncoin has offered i2p support since 2014..

That said, where is the innovation? There's no sender, receiver or transaction value privacy mechanisms.. On top of that the dev is censorsing any mention of privacy protocols i.e. Zerocash, Zercoin, Cryptonote, etc.. on the grounds that it's shilling other projects. Is it not justified to bring these protocols up in his thread? Especially one that is branding itself as:

XVG - "The Standard in Privacy Based Crypto"

or as their website puts it:

"A Secure and Anonymous Cryptocurrency with a focus on Privacy"

So as the title says: did John McAfee just ruin his reputation as a security researcher for pumping a shitcoin?
4  Alternate cryptocurrencies / Announcements (Altcoins) / [PRE-ANN] [XDB] Doubloon - Privacy Evolved on: December 07, 2017, 08:39:33 AM




Doubloon is a groundbreaking cryptocurrency research project that has pioneered many new improvements not present in any other project. The main highlights of our research efforts include a brand new Egalitarian mining algorithm called Itsuku along with pioneering our new trustless zero knowledge system.

This is a PRE-ANN to inform the general cryptocurrency community of our work here and how to get involved with testing cycles as well as the upcoming launch of Doubloon.


Doubloon is the result of over seven months of research and development. We intially started this project as a comunity effort towards a planned hardfork upgrade to Boolberry because the developer abdandoned that project. When we revealed our ANN our efforts have motivated the original developer to return to work on BBR. We also paired up with another team of researchers to pioneer a new zero knowledge protocol which will be the first of its kind. As holders of Boolberry we will continue to support that project during this interim period, although, our main focus will be on Doubloon. The timeline below displays the original path for the project:



Doubloon is a brand new privacy protocol and will be the first trustless zero knowledge cryptocurrency. Our research team is compromised of leading professors from universities around the world and our development team is compromised of veteran PhD and MSc level contributors. Our goal here is to establish a new benchmark for research and development within the cryptocurrency privacy vertical.

Doubloon will be fairly launched with no ICO. We'll be implementing a reasonable premine for research, development and marketing fund and utilizing a mining tax for ongoing project related funding. In addition will be providing an optional in-wallet donation address that will go towards the i2pd team for those that would like to contribute to their efforts towards improving the router. At the moment, our team is working is on a private repository while we refine the project until its ready for public testing.

In the near future, we will be releasing a public testnet for the mining algorithm followed by a public testnet for the rest of the codebase. After the code has been thoroughly tested, we'll announce our launch date which is currently planned for Q1 2018.


Coming Soon


We initially brought Professor Fabien Coelho on board to peer review the Cryptonight and Wild Keccak algorithms to see if they could be improved upon which also led us to review other promising algorithms as candidates to replace WK. We discovered the Merkle Tree Proof-Argon2, or MTP-Argon2, algorithm designed by Biryukov et al. of Equihash and Zcash fame. Biryukov and Khovratovich designed the Equihash algorithm in use by Zcash. Their latest design MTP-Argon2, or Mekle Tree Proof, was designed as a successor to Equihash with the primary function of providing an Egalitarian mining solution.

Professor Coelho reviewed this algorithm and redesigned it to be hardened against all known attack vectors along with optimized proof sizes, which is known as Itsuku. The new algorithm has 1/16th proof size of the original MTP-Argon2 design. Our research into designing and peer reviewing this algorithm has been shared with the ZCoin team as part of their bounty program as an attempt to unify and peer review the design. Marc Bevand research has also been crucial in helping improve the design.

One of the primary benefits of Itsuku is that the miners bear the resources burden while verifiers do not. This is a true egalitarian mining algorithm and unlike the current CN mining algorithms, one that has seen a substantial amount of active research and peer review from within the academic community. Initial spec is 2GB but in any case, even with 64GB of RAM there won't be much speedup, since the limiting factor is bandwidth and not space.

Dr. Coehlo is a professor of Computer Science at the prestigious MINES ParisTech, PSL Research University. His research into Merkle Tree Proofs and Proof-of-work algorithms dates back to 2007 before Bitcoin was launched. It goes without saying he is a true pioneer and leader in this field.

Arnaud Larroche and Baptiste Colin are two of Fabien's students at MINES ParisTech. They've written a Python implementation of the algorthm.
https://github.com/baptistecolin/itsuku

As stated earlier, our C++ implementation will be made public in the near future for testing along with a GPU miner contest we’ll be holding to make sure everyone has access to the same competitive mining tools.

In an effort to provide transmission privacy, we’ve integrated the i2pd router into the new codebase with advisement from the i2p team. 1776, the developer spearheading this effort has made a massive amount of progress in this area of the project and we will have a i2p design available at launch. He has a ton of experience in this area and has brought that into this project for peace of mind. In the future he will be submitting an improvement proposal to i2p team to increase efficiency.


A project can have the best technology but if it's not user friendly then it will be harder for less technical end users to adopt it. Keeping this in mind our designers have crafted a beautiful GUI wallet that includes features such as an address book, in-wallet explorer and mining. We will also be following up with mobile applications but they may not be ready at launch.



All in all, our efforts here will culminate into a new zero knowledge privacy protocol along with new egalitarian mining algorithm.

Our public testing for Itusku will be announced very soon so stayed tuned to this thread for updates. We invite everyone in the cryptocurrency community  to join us on this adventure as we pioneer the future of financial privacy.
5  Economy / Scam Accusations / Re: [SCAM ALERT] MSD = The new MLM scamcoin Tidex = Scam exchange on: October 06, 2017, 01:44:01 AM
I was introduced to the Tidex.com exchange while looking for an exchange to list Boolberry after it was delisted from Poloniex and Bittrex without justification.

https://cointelegraph.com/news/poloniex-to-delist-17-altcoins-in-may-without-explanation

Tidex itself seems to be a legit exchange with decent volume, nice interface, active support and backed by the team at Waves project. Apparently the same founder of Waves is the founder of Tidex. Unfortunately, they have a listing there for MSD. After being constantly bombarded in the trollbox by MSD bots I looked into the company behind MSD, "Monspace" and soon it became clear it was an MLM marketing coin similar in design to Onecoin.

Red Flags: No source code, no wallet, no information anywhere, no coin supply, no block explorer..  just bots in a trollbox promoting it as the next BTC

Youtube search reveals "Mike Thomas" self described "grand father of cryptocurrency" whatever the fuck that means. Most likely an actor hired to promote the scam to their own local market.

I can't stand this type of low life scum coming into the crypto scene to further their operations. In the end, it gives crypto a bad name and brings down unnecessary regulation.

http://www.freemalaysiatoday.com/category/nation/2017/05/13/monspace-scam-worse-than-jjptr-says-dap/

It's best to spread this information around as quick as possible before anymore people get scammed. I hope Tidex does the right thing and delists this abomination. One would think an exchange backed by the waves project would think twice before listing this shitstain of a project. Crypto is an experiment in self regulating free markets, without exposing these things before they get bigger it only opens the door for further regulation.
