2021-06-17 15:49:10 Rehrar Gets Paid a LOT!

Rehrar makes $7k/month (for 4 years) - to run a shitty Telegram group (where he doesn't moderate whatsoever).

He then sits here and tries to extort the community for more funding for some reason.

There are many conversations that I've had with 'rehrar' myself, so I'm going to go ahead and release some of the excerpts of our conversations to expose this bad actor.

2021-06-17 15:34:23 Monero Sunday Call (more of Monero being exposed)

Tried to tell the people in here how fucked up & corrupt this project was months ago and nobody wanted to listen.

So now you're going to have to get your hearts broken the hard way.

Watch this loser Diego get called out on Clubhouse and fail to provide any real answers (weirdo)

Check out this 'Monero Sundays' chat here:

(Diego is a snake and a fraud, but he runs the Monero community)

Much of what is about to be posted falls under the category of things that should be done as a precaution anyway as good practice - but we'll reiterate this here for good measure.

Before you read this list of recommendations, understand that this isn't financial advice and this channel isn't responsible for what happens to you. This is friendly guidance in an attempt to be constructive
.

1a. We're not going to tell you to stop trading on exchanges. Sounds crazy because after everything you've read from this channel, you'd expect this to be #1 above all else - but telling people in crypto not to trade is almost like the equivalent of parents telling teenagers to never have sex and wait until they're married. Its unhelpful. Teenagers will have sex just like people will trade. So you might as well educate them on how to be safe while doing it if they do it.

2. Moving your funds off of exchanges when you're done trading. You only need your funds on exchanges to execute trades but once you go to sleep, log off, etc., there's really no reason for your funds to be on the exchange. If the price starts sliding around, you'll take an L here, admittedly, and if you're in a contract (derivative/options), that could be a limiting factor as well. But if you can, you should seriously limit the amount of funds you have on exchanges. This is specifically addressing those lazy people out there that are treating Coinbase/Kraken/Binance/BitMax/KuCoin etc., like a bank out of convenience. Do not treat exchanges like your personal crypto bank out of convenience/laziness. If your funds don't need to be on there - move them to a wallet you own." (Keyword: 'need' ; the only person who can determine this is you & you're entitled to make any determination you want for any reason - you owe us no explanation. Its your money.)

3. Use fiat exchanges if possible. This is a weak one because there's no telling what will happen to the cashflow of major exchanges in this space if Tether/Binance/Bitfinex gets the hammer dropped on them one day. Ultimately, its up to the exchange to honor your withdrawal request. But at the very least, you want to make sure you're not in Tether at that point because then you're undeniably screwed. TUSD really isn't a better option and perhaps USDC will be viable, but again - consider that Coinbase has recently announced that there is no FDIC insurance protection for USDC holders in their Terms and Conditions. At least if you have fiat there, you'll have a legitimate claim & a strong case with arbitration (not legal advice, just an opinion).

4. Evaluate How Much You're Trading With and Whether You Can Live With Losing it All. Seriously. Your life is your life & the same goes for your finances. You have to live with whatever happens and whoever you pay owe bills or buy groceries from isn't going to cut you a break because you lost all your money on the internet because your "digital tokens" can't be accessed. If you losing every single penny you have on exchanges as this very second would put you in a position where eating/paying rent or mortgage/putting gas in your car or traveling/taking care of yourself or family would be next to impossible, you should seriously consider whether that risk justifies whatever gains you think you're about to get out of the market. Again, you have to live with this - no one else.

5. Don't Procastinate. If you read #s 1-4 above and thought to yourself, ' You know what ? I should probably _______, just to be safe ' then do it without delay. Now. Like, right this second - minimize or close whatever app / tab you're using to read this and just get your funds out to a wallet you own if this is something you've decided you want to do . Again, no one is telling you to do this. Don't message the author(s) of this channel because you "listened to us" and removed your funds. You make your own decisions as an adult. But if you've decided you want to move them off, just do it. Don't leave your life up to chance

2021-06-16 00:36:44 tl;dr - Proved that Bitcoin Actively Censors Any and All Dissent

You can disagree with the information presented above, but I think I made it more than abundantly clear that what I wrote & provided far exceeded the fucking bar for something you would REMOVE as outright misinformation.

1. The comment that I published opposed implementing Schnorr's currently

2. Schnorr's was crafted by Peter Wiulle (Blockstream)

3. The BIP was proposed by Blockstream employees

4. The person that removed my comment - Gregory Maxwell - is the "former" CTO of Blockstream (yes, this is true).

5. The vote on whether this would be implemented or not (via soft fork), was decided by Blockstream

6. The new Bitcoin version that included this latent activation code was crafted by Blockstream

7. CoinDesk is a huge supporter of Taproot & Schnorr's. They're owned by Digital Currency Group - which is also invested in Blockstream (https://dcg.co/portfolio/)

8. BIP 8 & 9 govern how the voting process takes place. Guess who decided that? Blockstream

9. Oh, and the vote? Well this is decided by the miners. Among those miners is Digital Currency Group (via 'Foundry') - whom are invested directly into Blockstream. There's also Blockstream itself, of course (they mine). And then we can't forget that Blockstream provides a suite of mining services for institutional clients. Among those clients, is billionaire Reid Hoffman. Oh, and billionaire Reid Hoffman is also invested into Blockstream.

Edit: Reid Hoffman is also on the Board of Directors for Blockstream.

2021-06-16 00:28:57 Determinism in Signatures

Those researchers state, "All of the attacks we discuss in this paper can be prevented by using deterministic ECDSA nonce generation, which is already implemented in default Bitcoin and Ethereum libraries." - https://eprint.iacr.org/2019/023.pdf

So if these attacks can (a) be prevented w determinism, (b) this is already hard coded in the default libraries of ETH & BTC - how is it fucking possible that these attacks were still carried out by the researchers?

The obvious answer here is that there must exist some wallet implementations that are not correctly using / forming edcsa keys and signatures.

Which is the exact conclusion that I came to in the comment that I wrote on Schnorr's - which is why I stated that they need to ensure that there is such an implementation first, before introducing Schnorr's (which would effectively make Schnorr's unnecessary if malleability was one of its goals).

Randomness is STILL Needed in a Deterministic Scheme

I'm not sure why they don't get this. The research cited above also makes clear that, "The signature nonce k must also be generated uniformly at random modulo n. If only a subset of the possible values module n are produced as nonces, techniques for solving the hidden number problem can be used to solve for the secret key 'd'."

Issue in the Nonce Generation

THAT is the part that can be changed (in a per-message fashion) & there is significantly different variability in wallet implementations (today at this very point in time, June 15th, 2021).

Follow-up that includes research (cited) on Bitcoin (from 2019; post-deterministic key change), citing the same issue.

Specifically, the researchers stated:

A) "In this paper, we compute hundreds of Bitcoin private keys and dozens of Ethereum, Ripple, SSH , and HTTPS private keys by carrying out cryptanalytic attacks against digital signatures contained in public blockchains and Internet-wide scans."

B) "The ECDSA signature algorithm requires the generation of a per-message secret nonce. If this nonce is not generated uniformly at random, an attacker can potentially exploit this bias to compute the long-term signing key."

The researchers credit "implementation vulnerabilities" as being the reason for the "biased nonce".
