    Is there interest in a Red Team analysis of CashFusion?

    Posted: 05 Aug 2021 09:53 AM PDT

    CashFusion's transaction privacy protocol is one of BCH's crown jewels. What if it could be made even more robust through a Red Team analysis? Red Team analysis is a concept from the fields of cybersecurity and military planning that involves investigating the strength of security measures by simulating attacks on the defenses and then developing improvements to those security measures.

    My question to you all is whether there is interest in performing this kind of analysis on CashFusion. It's almost a certainty that CipherTrace, Chainalysis, and their ilk are Red Teaming CashFusion for real right now -- and they're playing for keeps. We need to know what the weaknesses are, if any, and address them.

    Putting fresh eyes onto privacy protocols has been fruitful for other coins. Last year, a serious flaw in Wasabi Wallet's BTC CoinJoin protocol was discovered by external researchers. Just a few weeks ago an external engineer discovered a significant privacy bug in Monero's reference wallet.

    Didn't the June 2020 audit by Kudelski Security already do this?

    No, not really. The audit primarily dealt with ensuring that the protocol could not steal coins from CashFusion participants and ensuring secure communication channels while the CashFusion transactions were being negotiated by the central CashFusion server and participants. They did analyze the privacy guarantees, but not very thoroughly.

    One of the audit's recommendations was:

    Furthermore, a higher level of assurance could be achieved by providing a thorough security analysis of the protocol under realistic adversarial conditions. Specifically, we would recommend to add: A threat model...[and] more rigorous analysis of the amount linkage risks (the combinatorial arguments is a good start.)....The exercise of working out such documents may in turn reveal overlooked design aspects or unforeseen optimizations.

    The audit goes on to state:

    The authors of CashFusion argue that, for a reasonable amount of players and components, the sheer number of combinations makes finding these combinations impossible. However, we notice that this is only true for a pure brute-forcing approach. The problem in question reminds vaguely of the problem of bin packing where heuristic algorithms much more efficient than brute-forcing are known. It is not obvious how a direct reduction between the two problems can be found, but we recommend nevertheless checking carefully this security argument against state-of-the-art works found in combinatorics literature.

    I have confirmed with Electron Cash lead maintainer Jonald Fyookball that they have not yet made progress on this recommendation from the audit. If I were to do a Red Team analysis, I would follow responsible disclosure procedures by informing Electron Cash developers of all significant findings before they are revealed publicly, if at all.

    Who am I?

    Long-turn lurker, recently a participant. I'm an empirical microeconomist. That means that I use real-world data, rather than mathematical theory, to investigate economic questions at the level of consumers, businesses, and industries. While reading about bitcoin's skyrocketing price in 2017, I set out to see if I could prove to myself the hypothesis that bitcoin was just a classic tulip-mania-style asset bubble. I tried to keep an open mind, and the more I read the more I recognized that bitcoin does actually present a solution to many real economic problems. So I rejected my initial hypothesis and have since kept abreast of developments in cryptocurrency.

    To demonstrate that I've been around for years I am able to cryptographically sign a statement with the private key of a 2017-vintage BCH address and submit it to a trusted community member for verification. (Not publicly though since that address has been KYC'ed to hell and back.)

    As a start, I've built a simple public-facing web app at https://fusionstats.redteam.cash/ that displays basic stats about all CashFusions to date. The intention was to mimic https://stats.cash/#/fusion (which seems to be in maintenance mode at the moment) but with some additional interactivity.

    (Re-posting because my first post was caught by automod or something).

    How to keep regular people safe?

    Posted: 05 Aug 2021 05:37 PM PDT

    "Be your own bank" is cool and all, but millions of people get scammed every year. I expect a fair share of "they deserve it if they don't keep their wallet safe" replies, but I don't think that's fair and it hurts adoption.

    I'm not sure I feel comfortable having my mom use crypto who for the longest time blamed her 10 year old Windows Vista laptop slowing down coz I gave her a virus by installing Chrome…

    I would argue that "banks", or rather services that protect these people are needed unless we truly don't care if grandma Pauline or uncle George are gonna loose their entire savings and livelihood…

    Would like to hear some potential solutions and opinions on this topic.

    If you know someone new looking to try BCH

    Posted: 05 Aug 2021 08:11 AM PDT

    Send them over to r/BitTippersToo

    They will be able to pick up a few tips to get them started in a fun friendly sub.

    They will need to have a little bit of Reddit karma and age to their accounts to be eligible but we do this for a few reasons one of which is to try and stop people with multiple accounts claiming more than their fair share.

    The tips are small but will be enough to test out a wallet and see how it all works.

    I've only just restarted the sub so we don't have lots of members right now but I'm trying to make sure there's always at least a couple open posts that they can enter, be it a competition or a giveaway, where people have a chance to pick up a few bits 👍

    If you a more experienced crypto dude then please try us out and host a competition or giveaway yourself, currently it's mostly me lol but hopefully that will change, we want to create crypto users, not crypto horders so BitTippersToo has a strong "pay it forward" ethos.

    Come take a look, remember to read the "read first" post, first lol !! Drop a comment get your flair and see if you can win some coin 😁

    Shower Thought: Less people/Miners probably agreed to this Ethereum hardfork than people who agreed with >1mb blocks

    Posted: 05 Aug 2021 09:05 AM PDT

    I can't think of anyone besides the Ethereum devs that wanted EIP1559 and the fact that the devs put in that difficulty bomb in case of a chain split from not wanting eip1559 really shows that they don't care what the miners want imo

    Listen to Me Extremely Carefully on The Second Portman Bill Amendment Banning DeFi

    Posted: 05 Aug 2021 09:16 PM PDT

    Some of you may be tempted to go along with this last minute backstab by Portman and Warner where they completely remove protection for anyone in the space who is not a PoW miner or provider of software and hardware to secure private keys.

    You need to understand that the future of this industry is DeFi layer 2, whether that is on Bitcoin or something else. It is going to be a combination of layer 2 defi and lightning technology. There is a very clear ethos of censorship resistance for the most disenfranchised built into smart contract based systems, just as with bitcoin.

    I struggle to make this argument to bitcoiners because of ignorance about how US law works. Ignorance specifically concerning the Patriot act, Facta, The banking secrecy act, Fatf, SEC laws, and CFTC laws. Rest assured, they can and will carry these laws forward to use against any lightning application or DeFi product based on native bitcoin, any business operator or coder or facilitator of such technology, anywhere in the world, no matter citizenship can and will be federally prosecuted and extradited. If they find you they will extradite you. No one is safe.

    This is a direct ban on DeFi. On smart contracts in general on permissionless systems, to ensure that the only smart contracts offered are on permissioned systems they have backdoors to, full patent control over. I.,e banks controlling them as de facto censorable Centralized Exchanges.

    Do you want to live in a world with no DeFi? Do you only want centralized exchanges and the absolute guaranteed censorship on the global south that that entails?

    You cannot collect KYC on smart contract. They know this. They know it is impossible, and that it turns non compliant non us citizen into felony offenders. They will come for you. How do you think they intimidated Binance and Bitmex? How do you think they caught Mcafee? It is impossible for a normal smart contract to ban US citizens. Backends can't censor people.

    This means it is illegal by default. No one in the world can safely operate DeFi without KYC if this bill passes.

    No one in the world can safely operate DeFi without KYC if this bill passes.

    No one in the world can safely operate DeFi without KYC if this bill passes.

    Once that passes, then they will pass ESG laws to censor miners and run them out of the country. They're trying to pick us off one by one.

    C A LL your Senator. Tell everyone, explain to your friends, get the message out. This is them using a hydrogen bomb on us with no time, input, or constructive nuance. It is totalitarian, poorly worded, and incoherent and shows the Whitehouse clearly doesn't know wtf they're talking about and the Treasury doesn't care if they ban technology to the point of strangling it in the crib despite knowing it will lose more tax then it collects.
