Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Idea | Tip Nano to creators

Hey guys, my name is Tolik and I'm new to Nano.
I would like to tell you a bit about myself, and then about some ideas that I would like to share with you :)
I'm a content creator form Israel, and I have about 65k subscribers over my 3 channels. I'm also the first Israeli partnered on Twitch and been doing that for 8 years now.
Had a lot of fun with it for the first few years, playing my favorite games and earning good money, and eventually burning out hating the game that got me all my following. Our (Israeli) community exploded on youtube, but to make the most of it you need to make mindless trendy content, playing trendy and pretty childish games. I did that for a while, but it was too hard for my mind and I ended up burning out hard stepping away for a long while.
Back in 2013 I first stumbled upon the world of crypto and realized the potential of the blockchain and the implementation of that technology in our world. Not enough to buy enough to get rich, but I never even considered that it could get to the volumes it got to now. In 2017 when it exploded, I realized I had some leftover coins from 2013-14 and cashed out a few thousand dollars, with the pain it could have been millions if I was a little more aware. Oh Well.
A few years ago, I got into the world of self-development and got a new perspective on life. Doing only what I love and grooming a small but good community on youtube, not caring about trends, views, and money in my pocket.
A few days ago, a colleague of mine started to promote some unknown coin to his child viewers, basically, the premise is a coin that you could mine on your phone. Immediately I had some red flags popping off my mind, especially because he promoted some shady CSGO gambling sites that I didn't even want to look into. He of course had his promotion code for registering to the gambling site, and using the mentioned crypto (downloading the app).
If you can mine it on your phone, what would stop you using an expensive setup and just dominate the market? The fact that he advertised it as a get rich scheme, and the fact that it's a referral pyramid network, does not seem safe.
After looking into it I did not see any promise, especially after I found so many altcoins with big communities that his crypto didn't have, information that did not add up, and a bunch of weird stuff going on.
Because I started researching the crypto world (after so many years not being aware of what happened to it), youtube started suggesting me videos about it, one of them was u/SonderDev 's nanoPaint (Sorry I made SpongeBobs eye red) and started doing some research on nano and the technology. For 3 days I devoured all the info I can, reading most of the posts here on reddit, and joining on Discord and TG. I again felt that butterfly feeling in my gut, the one I felt so many years ago when I found out about bitcoin (and some other rare occasions). So much potential, and I kind of feel I am already late to the party, and yet, my mind can't stop thinking about what is possible.
Now to the good stuff! Donations(tips) to streamers and content creators were always a huge part of our revenue. But we had a lot of problems with it - High fees, making small donations pretty much impossible, and the fear of someone charging you back and having you pay the fees for every donation that got charged back. I had someone give me about $2k for the span of two months with small donations, ended up charging all that money back, and having me pay $10 for each of his donations, even if they were under that amount. PayPal is pretty crazy.
Also, If you consider something like Patreon (a monthly donation for a project or a creator you like for benefits) they also charge extra for their fee, and people can still charge you back, even though they will handle it, you still give them the benefits. Twitch takes a huge cut for subscribers (user pays $4.99 and I get as little as $1.70) and youtube are getting about 30% for their cut.
See where I'm going with this? As proof of concept, a simple donation website/app could be made. You send the creator any amount of nano, it pops up on the screen for everyone to see. People would love the idea to impact the stream with as little money the creator allows. That would start up a conversation, people would start seeing the technology in action, how fast and feeless everything is going.
Not to mention an integrated service could be made that is similar to delegate.it (allows users to do tasks for nano/fiat) in this instance, the tasks could be - follow the creator on Twitter, Instagram, like his posts and whatever else he decides, and it could be cheap, because people would be doing it to pop up on stream and help the creator, not for the actual fiat amount of the nano given. killing 3 birds with one stone. Promoting nano, allowing everybody a voice to a degree they choose, and promoting himself to his viewers.
If this works, we could either go to one of the 2 biggest platforms (StreamLabs and StreamElements (who are Israeli and I know the 2 founders personally)) and they would integrate it to their already build system, or develop something to solely promote nano. We could reach out to smaller streamers that have small dedicated communities, not many donations and revenue coming in and allow them to use our system to promote their content and interact with their viewers.
A few more ideas I have in mind for a project like that:
For the donations (tips)
• Having different donation alerts for different QR codes that you scan. Similarly to what NanoPaint accomplishes, we could have a different QR code to scan for an alert that the user chooses to show up.
• Coloring the Camera frame - similarly to NanoPaint, drawing pixels on the frame of the camera of the streamer, changing it in real-time for nano.
• Having text to speech for the alert
• Have your donation impact the streamer in AR (putting something on his face or head).
Crowd Funding
• Donation goal that will make a purchase only if it gets there - setting up an X day goal to buy a new GPU for example, and having people contribute to it, and if it's reached, it automatically makes the order from amazon or wherever (having the data safe with our service), and if it's not - fully refunding the users. It could be a daily goal for pizza or whatever they choose. It will allow integration with businesses that would work with us.
• Stream goals - if we get to X Nano this stream, 24 hour stream tomorrow! If we won't, get your nano back! Would encourage people to participate even if they are not sure the goal will be met, have the assurance that the full amount would be refunded if it did not get there.
• Challenges - starting a bounty challenge, for example, have an Ace in CSGO (kill all 5 enemies) and get X amount of nano. If you didn't, money goes back. the crowd could vote on it having more interaction and validating if the challenge is complete.
Voting
• Have people engage with polls in real-time with nano, could scan their option to vote, and even get refunded if their option did not win, encouraging them to vote for their favorite option, even if it seems unlikely to win.
User Battles
• Having people start a challenge of a game, in an app or on the web, or perhaps even something random like gambling, and having it appear on stream for everybody to witness. Maybe even challenging the streamer for a nano incentive or someone else who watches.
Chat
• Having an on-screen chat that changes the colors and design of the people who donated with nano, and linked their account. more incentive to donate.
Stream Sponsors
• Having a rotating banner on-screen at all times, allowing users to pay nano to show their banner. As an auction or a price set from the creator.
Most of these ideas occurred to me as I was writing this post, and I'm sure we could think of better ones with some effort. Some of them are already implemented on the websites that were mention above, however, having the power and speed of the nano is a game-changer IMHO.
So why am I writing this post? First, just to share with you and get to know you better, maybe spark an idea or a motivation for anyone to do something good for nano.
Second, money is tight now, moved back to my parents due to the pandemic, hard to find a decent job as we have more than %20 of the people in Israel looking for a job and as I mentioned before the content I make is not very profitable. I can't afford to invest money in this idea, and I lack the skills to do it myself. So maybe if it's good someone else could.
If, however, someone would be inclined to help make this a reality, I would appreciate any comments, suggestions, investment of time, or money in testing this out. I have a dedicated community with thousands of people that will be aware of nano if we'll do it, years of experience in this field, and not to mention that I'm in good relations with most of the other content creators and platforms here in Israel, and some international.

My Story of BTC

This is my story of how I derped around during the last BTC bubble, made some dough, and saw my friend pile up a mountain of debt on himself, only to become a millionaire. I hope if you read it there is a moral somewhere, but I'm not so sure there is. (prices are approximate to dates, going back in my memory a bit)
OCT 2011: (BTC $4) (preface)
As an undergrad computer science major I mined a few coins in a cyber security class . It took about 2 months and I think it was around .89 BTC or something like that (Edit: OK so I probably didn't mine this much, but I had access to the computers in the graphics lab and during this time, and they were mining 24/7. We let them run for a while after the class before taking our share out). I think it was worth about $8 at the time. I thought this was really cool, but also remember at that time you couldn't do anything with it, especially where I lived. I just kind of forgot about it, got a new laptop sometime later, and eventually chucked that one with the coins on the hard drive... (it was just $8 and I had no way of spending it remember) oh well so much for those. Who knows how many coins were lost by these standards back in those days. I take in all the maths, graduate with marks, drink all the beer, laugh with friends, fun times.
May 2015: (BTC $234)
Fast forward.. I end up in Los Angeles, CA through another long set of tales. I live with aspiring actors and film makers grinding it out as waiters and bartenders. They are good mates and take me to parties on occasion where we meet all kinds of characters. I end up chatting with a guy (lets call him Bill) who's nuts about BTC. I explain to him that I know all about it, and he is ecstatic to find someone who understands what he is talking about. I haven't been paying much attention the past years, and he shows me how far its come in tech and price. I smack my forehead, knowing I tossed away 8/10ths of a coin (could have been beer money man). We become friends and talk about Bitcoin pretty regularly.
I don't buy initially, but Bill is giving it all he's got, buying left and right with anything extra dollar he can scrape up. He believes in it. I get so worried that Bill is going to loose what he put in that I just buy a bit (.1BTC) so I will be invested enough to watch it, to know if Bill is up or down. You can guess what happens at this point. Up we go. Bill makes money, I make money.
June 2016: (BTC $661)
All is well. I am happy that Bill didn't lose his money and hoping he will take and re-invest his earnings in a more diversified portfolio. I'm worried about the ~$100 I made in earnings, like do I file this? (lol younger me)
I meet with Bill for the first time in a while. I'm excited to share our gains. We both show our gains and cheers. He immediately tells me that he is looking at ways of taking out credit to buy more BTC.... WTF? I say. He quickly proceeds to tell me the banks turned him down, but he found out he can just buy BTC with credit cards... so he is filing 7 applications right now to see how many he can open to buy BTC... I think for a second. I do the rational thing. I try to talk him down, but no way. He's doing it. I don't know much about investment at this point, just math and percentages, but thats enough to make me beg him to not do it.... he doesn't listen.
By my estimates Bill purchased a total of $30K worth of BTC with combined cash and credit on hand at (my best guess) an average price of $589 per BTC. I invest what I have to spare from savings to just keep up with the train wreck I am worried about happening to Bill. I think I have .2 BTC at this point just to keep up with his insane position
August 2016: (BTC $576)
The first dip comes, and Bill is facing credit card bills with interest rates that will kick in soon (he will not be able to make the minimum payments). We discuss is troubles at this point frequently. I suggest he should liquidate and close the cards. He disagrees, and liquidates only a position large enough to pay the minimums and give him a bit of cash. Not only that but he use the cash to secure short term loans at higher interest in order to re-invest to make up the losses. I once again beg him to re-consider, but no... this is his path. I once again invest more to keep up with it, so I can keep up with Bill and his well being. I purchase a good bit more and have .5 BTC
November 2016: (BTC$758)
I move to another city and mostly forget about my interactions with Bill. He messages me a few times about the price going back up and being bullish about it once again. I do the same song and dance of trying to warn him to close his cards and positions to get out while he can. Nope he's holding strong. Nothing to be done. I assume I can't do anything to help this situation. Once the price busts above $900/BTC even I can't say anything. I've made money, he's made bank. I feel happy for him, but once again concerned. I know he is running on margin and don't want him to get sucked in, but I also don't want to weigh in on such a big investment at this point. He texts me about the gains, I mostly just give the thumbs up back, knowing I can't back down at this point, but I don't want to be around him if it fails.
Jun 2017: (BTC $3000)
I have mostly lost touch with Bill because I live in another city. I never sold my BTC though, and I never forgot about him. Around Feb. 2017 I visited LA and saw Bill. I thanked him for making me the money that I held now in BTC. I asked him what he was doing with his stake. As always he was ready for the apocalypse to happen and for his BTC to be the only currency left somehow. He was holding stone cold. I wasn't persuading at this point, hell, I was holding myself.
Dec 2017: (BTC $16000)
While I thought I would never be swept up in the chaos that is BTC... I was. The amount of BTC I hadn't sold (.3BTC) was making even me feel like a genius. I had made so much money off just forgetting about something over months at a time. I often thought about Bill, but I didn't envy, in fact I really hoped he had paid off his credit card debts and was sitting on his fat profit. I watched BTC Youtube channels and debated if we would go to $100K or if this was it. I couldn't take the pressure and sold half my position @ around $16K/BTC
2018-2019 (BTC $20K -> $3.5K) (Epiloge)
In early 2018 price went up to $20k before quickly falling back to 10K. Thankfully I sold the rest of my position on the way down at about the same point as on the way up ($16k). I bought a few back in 2019 but have never really put as much capital back in as I made. As for Bill, well I told you at the beginning. Bill is a millionaire. My best estimates based on my text with him is he cashed out @ around an average of $17k/BTC. Even after taxes, he ended up real nice. I don't know if he was in the run up in 2019 but I must assume he was.
Looking at the market today, I'm not sure this story will repeat itself... maybe it will.

Urgent Advice Needed - Issues Refunding Money to a Client, Possible Money Laundering?

Hey everyone, so buckle up, this is a story.
I'm a freelance translator with my name and contact info out on several sites to connect translators to clients. So, when I got an email from my customer, L, I didn't think anything of it when she asked me to translate a research paper from German to English. Prior to even opening the document she sent me, I told her I wanted a contract signed - nothing major, just run of the mill stuff. You know, to make sure both of us were protected.
It entailed a 50% deposit for me (this paper was 46 pages and I have a policy that past X amount of words, I need a deposit for any time spent on a project. It's non-refundable, so I get paid even if the project gets canceled). She refused both of those things.
Like most people, I'm in a pretty tough spot right now. I knew I shouldn't have even continued speaking with her, but with my fee agreed upon, I was looking at almost $10,000 for the entire projected when all three phases were complete.
After refusing to sign a contract and agree to a deposit, she told me, and this is a direct quote "the money will be our contract". I was willing to operate on good faith, so I told her I'd get to work when the payment processed.
The amount we agreed on for Phase One was 1150.00, but she sent me - via her "sponsor", some random account in Arizona, even though she claims to be overseas - 7,176.00.
There was no warning, no notice telling me that they were sending me more than we agreed, or that the payment would be coming from Arizona. I contacted L and asked for clarification. She told me it was for payment for the next 2 phases due to start in the fall. I accepted that and kept working.
I finished the project 2 weeks before it was due and sent her the final document. Two days later, she sends at email telling me that the final 2 phases have been postponed and she needs the extra 6 grand or so back, asap.
Well, things happen, whatever. So I asked her how she wanted it returned to her.
This is where shit gets weird.
First, she tells me she wants it done via Zelle, which is connected directly to my bank. She sends me a contact and asks for all of the money to be sent at once. I tell her that since it's a new recipient, I can only send $500 and there's monthly limits on my account as to how much I can send in a 30 day period.
Now, her name is Lara, that's the only person I've been talking to directly. But the name on the Zelle account was Caldon H. I thought that was the name of her sponsor.
She proceeds to ignore my telling her about sending limits and demands a refund. I explain to her again, with screenshots from my banking app backing me up, that I'm limited by sending limits. I tell her that I'll repay her in $500 installments until all the surplus funds are returned.
Not fast enough. She then demands I use Cashapp. Oiy. This was a mess. I did reading and research on the app, since I'd never heard of it before and was alarmed to say the least. But she was sending text after text, email after email demanding a status update. She sends me another account to transfer the money to:
Linda. So, so far we have Lara, Caldon, Linda. Keep count of those names.
I ask who Linda is, no answer, just more demands. Cashapp, true to fashion, fails. I'm unable to add so much as a dollar to my account to send "Linda" and while I wrestle with this and try and find support to contact - HAH - I get payment requests via Cashapp and yet more emails and texts from Lara.
I explain to Lara, once again with screenshots showing that the app isn't working despite my linking both my debit card and checking account to it. She ignores that. Linda sends more payment requests.
I tell her, hey this isn't working. What about Venmo? Paypal? She ignores that and demands wire transfer. She sends account info for someone named Mark. I ask who Mark is, no response. I attempt to send the wire transfer via my banking website and the bank legit tells me that that account does not accept wire transfers. What...
So, more screenshots and then I ask her to double check account and routing numbers. She gets back to me with "the information is correct. Be patient when entering numbers." As if it's my fault.
So I try it again and it fails, again. After that I contact my bank directly and speak with their support line. We do the whole song and dance and they tell me that everything is kosher on my end, but the issue lies with the information I was given, confirming my suspicions.
I send her another email explaining everything, that I'd spoken directly with bank support. She tells me, once again, that the fault is mine and to just go to the post office and get money orders in $1000.00 amounts, leaving the recipient blank...
Yeah you read that right. Leave it blank. Overnight it via Fedex to some guy named James, in Georgia.
Arizona, Georgia, Germany. James, Caldon, Linda, Matthew, Lara.
I tell her point blank, I can't go to the post office. I'm in Idaho and COVID cases are skyrocketing. I'm high risk, so is my partner and one of my two roommates. Like, die for sure, high risk.
I try a wire transfer via Western Union instead. At this point, this has been going on for a week. I've been getting 4am texts and 6am phone calls for a week. She's on me for about 10-12 hours a day.
I'm a full-time student on top of this, with one more semester of undergrad. But classes have taken a back seat so I can deal with this.
Western Union holds the transfer under review and tells me that it will take 6 business days to show up in James' account. I tell Lara and assume that we're on the final leg of this mess.
Surprise, WU cancels the wire transfer. I call support and they tell me it's issues with the account I'm sending money to. I tell Lara and she starts getting snappy.
We try wire transfers for the last time, this time to someone named Matthew Green, different Matthew than the first, in Dallas. It fails. I spend $60 trying to send them. My bank calls ME and says they're concerned about fraud. I tell them I'm trying to send money and confirm info I was given. Once again, everything is fine with me, but it's issues with the account Lara wants me to send money to. I tell her and once again she changes her track.
She demands, again, money orders, same rules as last time and I tell her no, again and explain why. She ignores that and tells me to do Cashapp, again. We spend an entire day with me telling that I'm not comfortable with Cashapp. It's not dependabe, it doesn't work. There's no support for me to contact if things go wrong - which of course it will - and she insists. She ignores my concerns and insists. I tell her, fine, but I want a written and signed statement from you that you are demanding this and that I'm not responsible if things get messed up and you never get the money.
She signs a statement and the I try again. Same issues. I tell that, in another long email.
By this point, it's been 2 weeks. I'm stressed, drained and tired of her weird behavior. I tell her that I've been understanding and patient with her. I've tried to help her fix her mistake of sending too much money too soon. That we never agreed on that much money and reminding her that SHE refused to sign a contact that would have protected us both.
I tell her, Paypal or Venmo. No cashapp, no wire transfers (which I'm out $60 trying to send fyi). Paypal or venmo. If she doesn't have an account, find someone that does.
She sends me a Paypal account url for someone named Micheal. A new name. I ask who Micheal is, who are these people? Why are they all over the US? She ignores that, demands the money. I try to send payments, but I can't send more than $5 to MIcheal at a time.
I tell Lara and she blames me. Says I'm not doing it right. I'm supposed to send payments in multiple transactions of varying amounts, small to large. "No Tracking info", whatever that means.
I tell her, look, I can't send you anything. Check your account info, I'm tired of this BS. She sends the same info again, nothing about her contacting support for once. I try again. It fails, same issues. I contact support myself and they tell me - - you guessed it, my account is solid. Hers is not. She is why the money isn't going through.
I tell her that and suggest Venmo. At this point, I can't think of anything else and I'm planning on contacting my bank to ask advice, but my last request for Venmo was made at 11:30pm MST. I'd been dealing with this since 8am MST. I was tired, done. I sent that email and screencaps and turned my phone off for the night.
I get up this morning, make my coffee and check my work email. I get an email form Lara saying that I'm the reason the payments are failing "once again" and "following my instructions, now. Send it via Venmo, no tracking info. Do it now."
I decide to be a sport one last time. I try Venmo. It fails.
I'm writing this post to ask for what other steps, legally, I need to take to protect myself. Once again, she didn't sign a contract. I've saved all emails and texts, and all of them show they we agreed on 1150.00 as payment for this job.
They show that I've tried to return the money to her over the course of 2 weeks. She refuses to let me speak to Coldon, Linda, Matthew Green, Matthew M, James (who she claims died yesterday), or Micheal Brown. She answers none of my questions. She sends aggressive emails and so many texts that I had to block her number on my phone.
I'm completely at a loss. The longer this goes on, the less legit it seems and I need some advice. I plan to speak to my bank today and ask if they can refund the money to the account that paid me. I can't get info on that account from Lara, no routing or account numbers. So my hopes are slim.
I have no idea if Lara has any legal recourse or ground to stand on, since she refused to sign a contract and all attempts to return the money to her have failed. As I said, I've saved all emails and texts showing that I tried to work with her.

Any ideas? Anything would help. I want this to be over and done with.

UPDATE: I contacted the fraud department at my bank, explained everything and they said that we see that you've attempted to return the money multiple times and none of it has worked. They said I have 2 more options:
"If they really want that money, offer to send a personal check. We'll start a research claim in the meantime and that will take up to 10 business days to either be resolved, or you will be contacted by a member of the Research Claims department."
I asked what my options are if they refuse a personal check and the banker said "Then you've done everything you can. Wait for the research claim to be resolved or to be contacted. You've done everything you can up to this point and we can see that clearly."
Lara has refused a personal check, demanding a cashier's check instead. I told her "My bank advised me to only send personal checks, not cashier's check. There must be a name and a legit address. I will not leave it blank."
She asked me to send it via bitcoin.
My reply: No. I have filed a research claim with the fraud department of my bank to get to the bottom of this. They will resolve it as they see fit.
That will be my last communication with her.

Fastest and easiest way without a minimum purchase or high fees for customers to obtain NANO? (USA)

Hello Nano community,
Some of you may know me from /nanotrade or elsewhere, I generally am bullish on NANO and try to do my part to help spread adoption and awareness. I also run several e-commerce websites utilizing the open source Zen-Cart as my back end. Lately, and not so lately but in general, I have encountered issues with various payment processors (which actually led me to Nano in the first place, as well as a general interest in Cryptocurrency).
While there are solutions to dealing with the more stringent regulations enforced by payment processing companies, many of these require my customers to download third party apps or sign up for third party services. Not too dissimilar to how Paypal requests a user to be logged in before sending a payment in fact. Anyways, so while setting up my websites again today after losing another payment processor over the weekend, I have come to the decision, why not try and introduce my customer base to Nano and present it less so as a cryptocurrency, but more so as a digital decentralized payment solution? I have tried accepting cryptocurrencies before, however many of my customers, at least for my main e-commerce website are older and not so tech oriented. Just seeing that I accepted "Cryptocurrency" and "Bitcoin" as an option was enough to scare some of these people away. Ironically, I noticed more sales when I completely removed this payment option and all mentions of it from my website. Funny how that works.
Anyways, since I am in the middle of setting up additional payment methods, I figured now would be a good time to attempt the above with Nano, and offer a link on the "Pay with Nano" page during the check-out process for my customers to decide if they would like to try it out. My only concern, many of these people being older and technophobic, is that the process for obtaining the Nano they want to spend may be too much work and not something they would be interested in. Especially if it involves things like scanning IDs or providing more information than a simple credit or debit card number and a name. Ideally, this would be the only information they need to provide, with the ability to purchase any amount (most orders placed are between $25-$100), without paying an outrageous fee (which I will offer an incentive to cover for anyways I think). An instant transfer would also be a prerequisite. Something as fast as it takes to sign up for Cash App for example.
So, am I asking too much? Do such services exist yet in the US?
Quick rundown:
-Low fees
-No minimum or low minimum
-Non-invasive signup process
-No wait
Another thing worth mentioning, and hopefully this can provide the right people with an idea which I think could really help improve Nano adoption if implemented, was that I noticed some competitors of mine are accepting something called "PMC Coin", which is claimed to be a gold backed cryptocurrency. The gold bit is not important I do not think. What is impressive however, is that these vendors are able to provide this crypto as an option during the checkout process, and upon hitting submit, the customer is brought to the PMC Coin website, where they are presented with a form for purchasing this crypto. I have not tried going further than this, but the form contains all the required fields for a credit and debit purchase, as well as the price for the purchase being exactly what the price was for the requested items during the check-out on the forwarding website. It appears that upon purchase, the credit/debit card payment is sent to the PMC Coin sellers, and the PMC Coin in an equivalent amount is sent to the vendor. I assume the fees are offloaded onto the vendor at this point. While I have no interest in this asset in the slightest, I have to commend them on this solution, and I really hope we can see something like this emerge from the Nano community. It could be the killer app we have all been waiting for to spur adoption perhaps.
I will essentially be manually doing something like this for my customers, albeit with links and instructions, however as mentioned, the more streamlined the process is, the better. I am sure they will have an easy enough time with Natrium, and I am excited to introduce some new people into the space. But most of all I just want a simple ability to be able to keep my shop online without having to bow down to the banks and their petty requests as to what products should or should not be sold. None of us should have to deal with the Soup Nazi, be us merchants or consumers.
Thank you for your time and interest, and remember, stay bullish!

Coinswitch.io: 100 Nano = $117 vs. $99.28 USDT (Binance) [$17.72 fee] [$63 minimum] (Simplex)
Coinify.com: 100 Nano = $119 vs. $114 USDT (Binance) [$5 fee] [$63 minimum] KYC is intensive but not too crazy. 2 Minute verification too. Definitely the best option so far. Only problem is the minimum purchase.
Going to try Binance.us next and the Brave browser, which I think uses Binance as a backend anyways.

1. What is Energi

Energi is a self-funding (no ICO and no premine) cryptocurrency that has a purpose to become the world’s leading cryptocurrency with the unification of Smart Contracts, Governance and Self-funding Treasury to ensure longevity and enable rapid growth. You can read more about why we decided to self-fund and chose not to conduct an ICO here.
Energi provides a small allocation to Proof-of-Stake (PoS) rewards, takes a bulk of the coin issuance and gives it to its treasury and active Masternodes. Energi also allocates 10% on-going reward to the leadership of the Energi Backbone, which is significantly less compared to today’s ICOs’ rewarding their founders between 20–50% of the tokens distributed. Another trait that sets Energi apart from ICOs is they give an on-going 10% allocation through each block reward, rather than rewarding the founders up-front.

2. What are the Fundamentals of Energi?

  • Scalability
1 minute block times and a 2 megabyte block size limit provide Energi with a vast transaction capacity for regular on-chain transactions. This allows for plenty of space on the blockchain for extremely fast transactions with very low fees.
Energi features a powerful on-chain scaling solution with a system of incentivized full nodes called Energi Masternodes. A Masternode is a full node backed by 1,000 NRG collateral that provides level 2 scalability to the Energi Cryptocurrency. 40% of the emissions of Energi is allocated to Masternodes, providing an extremely strong incentive to grow the number of full nodes and scalability of the network.

  • Funding
A key feature of Energi is its powerful treasury system. Energi makes up to 40% of the emissions available to the treasury, to be utilized in a manner that provides maximum benefit.
Treasury allocation is decentralized, allowing for submitted proposals from anyone, to be voted on by Masternodes and paid out from the emissions.
Energi has a 14 day treasury cycle, allowing quick payments for proposal authors and contributors, as well as strategic responsiveness to effective proposals. Energi is guided by the principle that every dollar spent from its funding model should yield more than one dollar of value in return. Thanks to a 14 day treasury cycle, the Energi team is able to measure results and respond quickly to changes in strategy.

  • Governance
The Energi Treasury is a decentralized governance model designed with Masternodes as caretakers, with voting rights on how to best utilize treasury funding.
This governance model reduces risk by allowing participation from everyone who holds 1,000 NRG as a Masternode. In this way, the Energi community can work together on how to best build the strategic direction of Energi.

  • Inflation
Energi Cryptocurrency has a simple rate of inflation at 1 million coins per month with no maximum cap. This ensures consistency in funding allocation, Masternode rewards, and PoS rewards, making the economics of the cryptocurrency more understandable for everyone who chooses to participate in Energi.
No coin supply limit ensures that Energi is prepared for the long term, avoiding “bubble” economics caused by dramatic early inflation that in most coins only serves to benefit founders ahead of increased adoption.

  • Distribution
Energi conducted a fair launch on April 14, 2018 with no ICO and no premine. Prior to launch, the Energi team gave a specific time and date for the launch of its main net, which its vibrant community eagerly awaited, so that mining could begin fairly, again avoiding centralization among the coin founders (It's important to note that Energi has transitioned from Proof-of-Work consensus to a Proof-of-Stake consensus).
Energi Masternode payments were designed to begin at block 216000, which occurred on September 18, 2018, almost 160 days after launch. This ensured time to list Energi on exchanges, and to grow the community, encouraging fair and equitable distribution before the extremely powerful Masternode rewards began. It is all too common for Masternode coins to feature a premine, which has the effect of centralizing distribution among the founders and early adopters.
From 2018 to 2020, Energi distributed nearly 4 million coins to users who contributed to spreading awareness of the project with social media activities about Energi, such as tweets, follows, and subscriptions on all major social media platforms.

  • Decentralization
Decentralized governance with Masternodes helps to ensure everyone is able to participate in Energi and help guide the project to achieve the best results. The change to the requirement to run a Masternode, from 10 000 NRG to 1 000 NRG, has allowed more people to be involved and boosted decentralization for the whole project.

  • Long Term Vision
All of the above features seamlessly work together in concert, to ensure that Energi is prepared for the long term. Rather than try to closely find a niche in the market, Energi is prepared to adapt and overcome all challenges for many years to come. Energi’s use case is that of a traditional cryptocurrency, such as Bitcoin. However, Energi’s strategy is to excel by avoiding the pitfalls of previous projects, while further utilizing and improving upon the most powerful ideas in the cryptocurrency space.

3. Coin Specs

Ticker: NRG
Block time: 1 minute.
Hashing Algorithm: Dagger-Hashimoto (similar to Ethereum).
Masternode requirements: 1,000 Energi.
Treasury cycle: Every 14 days.
Approximately 1 million Energi will be released per month. The allocations can be observed easily as “10/10/40/40.”
10% will go to the Energi Backbone.
10% to the PoS participants
40% to Masternodes.
40% to the Treasury.
Thus, for every block, allocations are: 2.28 Energi to the Backbone, 2.28 Energi to the PoS participants, 9.14 Energi to the Treasury, and 9.14 Energi to Masternodes.
Since Treasury allocations are paid in two-week cycles, they are made in lump sums of approximately 184,000 Energi every 14 days.
In order to allow for widespread distribution of Energi before Masternode payments began, Masternode rewards were delayed until day 150. This was to allow the airdrop campaign to be completed and ensure a large amount of NRG is spread out through the community. Until that poin
