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).

Merchandise idea: Moonopoly!

In response to the post about merchandise pinned here , I was wondering would it be possible to create a custom cryptocurrency version of Monopoly called (of course) Moonopoly! Christmas is just around the corner and it would make a great gift to a fellow crypto enthusiast, or could even be given out as prizes!  
Anyway, regardless of whether or not this is a good idea that can be taken seriously, or something completely ridiculous, I figured we could have some fun now deciding how this game would hypothetically be played and allocating the squares for the board. Here are my ideas:  
It would work just like normal Monopoly which we're all familiar with. But instead of being handed out a set amount of $ or whatever, the currency for Moonopoly could be Dai/Satoshis...or even Moons!  
Instead of the 28 properties we could have 28 cryptos. (Just like in standard monopoly, their value doesn't have to be exact to real life.) Bitcoin and Etherum are the equivalent of the premium properties (Mayfair and Park Lane on UK Monopoly). Perhaps nano could be the cheap Old Kent Road (Don't hate me nano fans, I love nano really. In fact nano could be the Free Parking square!)  
So let's say you land on the Bitcoin (Mayfair) square and want to buy it. That will cost you 0.1 BTC. If someone lands on it, they have to give you 0.01 BTC. Instead of building houses and hotels, you can add more Bitcoins/Eth etc, which would then increase the amount someone would have to pay when they land on your crypto.  
The 4 railroads could be exchanges (Binance, Coinbase etc.) and perhaps the two utilities could be something deFi like Uniswap and Honeyswap.  
We could have a lot of fun with the Chance and Community Chest cards. Here are some ideas:  
-You entered your seed in a phishing site. Pay 0.3 BTC.  
-You've received an airdrop. Collect 0.2 BTC.  
-Binance has been hacked. Pay 0.5 BTC.  
-Bullrun confirmed! Collect 0.4 BTC.  
-The ICO you invested in has exit scammed. Pay 0.2 BTC.  
-You didn't file your crypto taxes. Go to jail. Don't pass Go. Don't collect 0.1 BTC...
 
For the pieces (i.e. the dog, the boot, the hat..) we could have:  
-Doge  
-Carlos Matos  
-Bogdanoff  
-Victor Cobra?  
Alright, it might sound a bit silly. I mean who are we going to play this with? But let's not worry about that. I want to know, what would you have on your Moonopoly board?

Top 5 Misconceptions About Blockchain

When we are faced with a new technology, we often look for analogies to understand and describe it. To bridge the knowledge gap, we seek analogies from the universe concepts familiar to us.
In our search for the right analogies, we often risk misunderstanding this new technology. Blockchain technology has introduced a paradigm shift in the way we organize ourselves to generate, account for, transfer and store value. Yet, we are still in early stages of understanding its importance.
In this post I will try to shed light on the top 5 major misconceptions about digital assets and about the open blockchain—a technology that underlies them.
1. Blockchain, not bitcoin
This misconception stems from failing to realize why blockchain exists in the first place. In essence, blockchain is a shared ledger designed to function in an extremely hostile, open environment. It derives its value from the security of its tamper-proof records.
In the blockchain networks powered by proof-of-work (PoW) algorithms, that security is achieved by miners competing to solve a computationally intensive puzzle. The miners do this with the expectation of receiving a digital token as a reward. This digital token can be freely redeemed for fiat currency to cover their operating costs and generate profits. These open systems are designed in such a way that value of their token ultimately dictates the level of security of their network.
When we decouple the concept of blockchain from its underlying token, it simply wipes out most, if not the entire, value proposition the blockchain as a concept.
Implementing blockchain as a token-less system of recordkeeping within a single company is perhaps the prime example of this misconception. Such an endeavor fails to use one of the most valuable properties of the open blockchain. Implementing a blockchain solution in such settings may even be counter-productive especially when better alternatives exist, in the form of databases with proper access control.
Blockchain could be useful in a commercial setting where a consortium of companies decides to use a single ledger to keep track of important transactions. An example of such transactions could be shares of companies that are traded on Wall Street millions of times each day. These transactions are reconciled periodically between the financial institutions by a trusted third-party entity, which could be ultimately replaced by a blockchain-based protocol at a fraction of their cost. That said, these systems may never become as secure and tamper-proof as the open blockchain as the security of the network depends on the number of its minestaking nodes.
2. Exchange Hacks = Digital Assets Are Not Secure
Centralized digital asset exchanges are popular avenues for exchanging digital assets for currencies such as USD or other digital assets. However, their design creates a system of incentives for external or internal actors to compromise them.
When we hear about exchange hacks in the digital asset space, it almost always involves compromising the security of an entity that operates within the traditional server-client architecture. However, the mainstream consciousness conflates the digital exchange security with that of technology that underlies digital assets. Holding a digital asset in a cold storage is extremely secure. Holding it in an exchange is not.
3. Blockchain has low TPS, hence it will never compete with or replace traditional financial infrastructure
Traditional financial systems process a vast number transactions every day. This transaction processing capacity is called throughput and is measured by a metric called transactions per second (TPS). Payment networks such as Visa claim to process up to 56,000 TPS, while traditional exchanges are likely to have much higher capacity to process transactions to accommodate high-frequency trading.
Today, the Bitcoin network processes around 4-5 transactions per second while the second largest digital asset network—Ethereum processes around 15. If we compare the current state of the blockchain technology to the demands of the global financial industry, it is easy to see why such claims could be justified. However, this is a myopic view of this new technology, very much akin to the way Kodak dismissed digital cameras as a potential threat to its business model.
It failed to recognize (i) the speed at which digital cameras would develop and (ii) the fundamental shift the digital cameras introduced in the way we take and store pictures, despite being the company that invented digital cameras in 1975. As the history shows, that was Kodak’s grave mistake.
It is hard to ignore the historical parallels here. The digital asset space is evolving fast. The next-generation networks, which operate under the proof-of-stake consensus mechanism, preserve the securities of proof-of-work, but do away with its capacity limitations. A notable example of that is Cardano. These new networks also represent a shift in the global economic paradigm that many do not seem to notice.
4. Digital Assets Have No Intrinsic Value
The concept of intrinsic value, or lack thereof, is often used to describe digital assets as a purely speculative asset class. While this may apply, with some justification, to digital assets which only claim to function as money, such claims fail to capture the wider nature of platform-based digital assets, which derive their value from the direct use of their networks.
In digital asset platforms like Cardano or Algorand, the native token gives the holder the right to participate in the consensus of the network through the process of staking. The consensus mechanism secures the network, maintains the decentralized ledger, enables participation in the governance of the network and can sustain myriads of decentralized applications with real-world utilities.
Put simply, digital tokens may derive their value from the economic activity that takes place on their networks. The economic activity on such networks, in turn depends on the security of the network, its technical capabilities, its transaction fees and the real-world utility of decentralized applications that reside on them. In that respect, they can be thought of as a new kind of financial instrument. The kind that seamlessly combines the properties of currencies, commodities, and shares of ownership into a single digital token.
These new instruments require that we develop and apply new analytical frameworks to value them, much like the concepts of equities and derivatives did when they first emerged as new financial instruments.
5. Developed Economies Do Not Need Blockchain Technology Because They Have Well-Established Financial/Commercial Solutions.
While it is easy to see how the blockchain technology could unlock a lot of value in the emerging markets, the idea that developed economies do not benefit from this technology is short-sighted.
It is akin to saying that cell phones are a great technology for emerging markets, but developed markets already have land lines, hence do not need them. In a similar vein, we could argue that developed countries do not need internet because most of what internet could do already exists in analog form.
We have to realize that (i) at its core, blockchain is a paradigm-shifting infrastructure/technology and (ii) despite its nascent stage, blockchain is extremely cost-effective… To a degree that it has the capacity to fundamentally disrupt a slew economic sectors out of existence, from banking to real estate, and create new ones.
When we accept this eventuality, we will have to face some uncomfortable truths that many sectors will not exist in their current form or entirely disappear. Currently these sectors provide economic value, employment and generate taxes. If some blockchain-based solution is to replace them in 3-5 years, where would that value migrate? Losing them to open blockchain networks would not be acceptable politically or economically for many developed countries.
One way out of this could be for developed countries to invest in national networks, allowing them to reap the benefits of this new technology, while retaining value from economic activity of their citizens and companies within their jurisdictions.
Another, more realistic way, would be to invest heavily into friendly legal frameworks that would encourage both individuals and companies that would ultimately develop or maintain open blockchain protocols migrate to these jurisdictions, drawing in talent, capital and innovation.
One thing is becoming increasingly clear: we can no longer ignore the elephant in the room. Much like digital cameras and internet itself, blockchain is unstoppable.

HELOC straight into stock market?

Little about me first and foremost so I’m not dismissed as a WSB hack. 38 years old, net worth about 3 million. Income is about $500-700k a year. Recently moved to Puerto Rico where most of my income now is taxed at 4% with 0% capital gains tax on any equities I buy while living here (homes and assets in the state’s are taxed by IRS but my income falls to about $50-100k on the mainland which helps for overall tax bracket). No debt other than monthly card. Own house stateside that rents, own some land, and am currently not married or have kids. Life is good.
The HELOC DILEMMA: so every one of my Uber rich friends are getting home equity lines because rates are super low and they 1) like have big loan approval for quick purchases of discounted assets and 2) like putting low interest money to work in higher interest paying equities (stocks, gold, bitcoin, real estate, new businesses etc).
I like risk taking to some degree but I’ve never liked risking my primary house. Now that I live in Puerto Rico and rent the home I actually live in, I’m wondering if taking a HELOC on my investment home stateside is a decent idea. I’d mainly want this approved line of credit so that if I find my dream home highly discounted I could pull the trigger quickly (I believe we could be heading towards a massive housing market correction). That being said, I can’t help but wonder what a HELOC would do if I allocated it all in the stock market. Again I’m not a big risk taker but mathematically it doesn’t seem like the worst idea (until it is right?).
I’m getting approval for a $300k loan at 5.234% for 10 years. If I run the amortization schedule on this for 5 years (and I think I read the rate can’t change for 60 months), I will be paying $41,748 in interest for the duration of the 5 year loan. If I were to put all $300k in the market and diversify it but still place it heavily on FAANG type tech stocks and maybe even gold/silver, I can make $125,000 in 5 years with a 7% interest rate. All in all that’s $83,000 gains in 5 years with a modest 7% gains. 10 years changed things to about $203k at 7% gains. Keep in mind, many of these tech stocks have done much much better than 7% per year but I’m trying to be reasonable here.
You see my obvious question. Unless we see stocks divebomb or move completely sideways for 5-10 years, how would this not be a decent play? Keep in mind, this $300k is currently half the equity in my house with my home being modestly priced at $600k (I think it could be closer to $800-900 when looking at comps that have sold). At the moment my home is completely paid off. I like the 5 year term because the rates should be locked in if I read that correctly. Puerto Rico also makes this interesting because as long as I live here for the next 5 years, all the gains on this deal will be taxed at 0% regardless of what the next Congress might pass with or without Trump as president.
I don’t understand hyper inflation and some of the doomsday scenarios I’ve been reading about but if the dollar were to stumble, perhaps my debt would be eaten away as long as my interest rate remained constant. If the HELOC has a variable interest rate at any time or after the 60 months, hyper inflation could be awful for this scenario but hopefully I’d just pay off the loan right away even if that meant selling other assets.
I’m sure this is a game many of you have played or have considered playing. Again, my main thought process with the HELOC is to just get approved for one and not use it at all so that if I see a foreclosed property or want to make a deal quickly, I’m already approved for a good chunk of the down payment. Thoughts?

[ Bitcoin ] Technical: Taproot: Why Activate?

Topic originally posted in Bitcoin by almkglor [link]
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 private 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).

Bitcoin challenged my comprehension of money. and from that, governance too

Social Media hacking jokes aside for today, I thought to share a thought experiment I had on how bitcoin fundamentally challenged the way I view money forever.
I was always told throughout life and even in school that money distributed by the government, managed by the government, but used amount the populus. It wasn't until I was 17 in my senior year where I learned about the in-depth concepts of money with topics such as Federal Reserve Banking (How banks make money), taxes, debt, and fiscal and monetary economy. What's funnier is that when I was 14 I heard about bitcoin, but I thought it was just an idea for some far off technology like Nuclear Fusion or Astro mining. So I'm happy to state I learned more about bitcoin before I learned about my own government monetary system. Unfortunately, It would not be for another 2 years before I learn about cryptocurrency and blockchain entirely and another few months before I can actually buy some.
It was at the moment when I fully understood the concepts of bitcoin where I fell in love with it, the idea that NO government, company, or bank could just step in and take your money. No overdrafts, chargebacks, or no 3-5 days deposits. It is great. I get excited to the point I share all I can to people around me about the concept and yet they are confused like a child learning a new language because the concept of true financial responsibility and digital sovereignty can be complex to comprehend. Many of them refer to the same statements: "Money should be protected and held by the bank so I trust that it will forever be there". As I think of it more I start to think of ways how blockchain technology as a whole can be implemented into fintech (or even become the new fintech). Henry Ford once said that
" It is well enough that people of the nation do not understand our banking and monetary system, for if they did, I believe there would be a revolution before tomorrow morning."
It is merely with the introduction of bitcoin and decentralized finance tools when this quote incubates into fruition. Cryptocurrency as a whole puts the individual in power with the same banking tools as the whole banking collective operates on. I agree that there are many people who are fed up with the banks, and their practices but at the same time those people are even more scared to assume their own financial control due to immense responsibilities the bitcoin introduces (private key, cognitive understanding of the industry and tech). Yes, banks are here to provide a service to the public ease and use, but therein lies the question of how much freedom do people really want when they realize that they are also baring even more responsibilities than they are used to. Great power comes with great responsibility. The more financial freedom (I'm not talking about in dollar amounts, but security and accessibility ) you have over your wealth the more responsibility is needed to maintain it. So then more so this brings furthermore changed my perception that I don't have to be so reliant on centralized parties with my money, but I can own my money on the blockchain and send it anywhere where in the world as I deem fit.
So this brings to my thoughts of how would blockchain systems work in government and laws. The laws are barely adapted to handle the internet as is; now they are further behind to handle blockchain. With coronavirus going around this is a testament to show how we are becoming stronger digital society. I have not been out of my home in the past few days, and most of the older ways of doing things are becoming challenged with the introduction of new technologies. The only thing that defines our governments are the lands in which was founded, discovered, or concurred by winning factions and ideals that ultimately curated most of the cultures we see today. We can speak to anyone we can on the internet in a matter of seconds, make a full-time living, we can buy nearly anything and get it delivered on the same day or week, and be associated with communities that align with our interest all online. So when these apps have more data and international relations than the governments we reside, can governments be more than just "land"?
Finally, this brings into question Facebook and Libra. Facebook is one of the largest public multi-national countries on this planet, and libra in eyes of many just a software update. However, Libra shined a light on so many things I've always wondered. With as powerful as Facebook is that probably knows more about you than your government, and has more international relationships with more countries than your government, if/whenever libra is released, this now puts a corporate entity in charge of your money. And As they say, libra existing on blockchains, really can't be stopped if ever it's released. Sure governments can be banned and sue Facebook all they want, but if there are people using it, the damage is done, they can't shut down Facebook without causing an economic collapse probably one worse than the great depression. Facebook is just too big to fail. Google, Amazon are other companies seeking to challenge governance by cities for their corporate entities and employees. They most likely won't be here in the USA too much regulation, but someone where like Africa or even cities on water .
All in all, as I leave, Everything I knew about finances such as mortgages, paychecks, loans, mediums of exchange, trade, and banking tools are all fundamentally challenged by the introduction of bitcoin. The power lies in those who own the system, and when no one owns the system, but everyone manages it, the real power becomes invested back into the people. With this knowledge, I know that I am truly more powerful than I thought I was, and you should feel empowered as well. Sure the infrastructure may take time before things become convenient enough for wide-scale adoption, but we are the founding fathers and mothers of the first generation in the true power of decentralized tech. We are the ones that decide on how the first implementation of this tech should be used, and that's all by experimentation. I agree that it will be a daunting task and scary for those who are not familiar with this. Like all things that exist it starts with experimentation.

Twitter Hack

The news is reporting it as a Bitcoin scam. It's not. It's a direct attack by a sophisticated group.
I know this for a few reasons.
1) All Bitcoin that was "stolen" is publicly registered, so none of the Bitcoin can even be used.
2) There are much better ways to scam money than hacking large accounts for a phishing scam. Namely one could post that Elon Musk has passed away (one of the accounts that was hacked), and short Tesla stock. Untrackable, unlike Bitcoin.
3) This is one is separate from the other two, but why were only leftist accounts hacked? All had two party authorization, meaning all nine or ten people's phones are hacked. Coincidence that they all so happen to be hardcore leftists... Hmmmmm
4) Also, now that those accounts were hacked, all Direct Messages from those individuals are exposed. Imagine the type of danger a country could face if all of it's leaders communications are exposed.
5) One day before the largest cyber attack in history, President Trump's passes a sweeping bill targeting China.
At this point we all have to see what is really happening. Everything that is happening this year is because Trump is attacking China. I believe even this pandemic has root in Chinese Government. What so happens to be funny is all of these people that were "hacked" have financial ties to China
Go look at the disgusting things China is doing; taking land from other countries that "belongs" to them, taking and demolishing homes from their own people, putting their own people in internment camps, and harvesting their organs to sell.

The Elites Twitter Accounts were not Hacked. They sent money to there breakaway civilization.

The Twitter accounts of some of the most prominent U.S. political and business leaders, from Barack Obama and Joe Biden to Jeff Bezos and Warren Buffett, were hacked Wednesday afternoon in an apparent effort to promote a Bitcoin scam. The attacks were stunning in scope and almost certainly coordinated. Others whose Twitter accounts were caught up in the security incident included Bill Gates, Elon Musk, Kanye West, Uber Technologies Inc., Apple Inc. and Michael Bloomberg, the founder and majority owner of Bloomberg News parent Bloomberg LP. The accounts sent out tweets promising to double the money of anyone sending funds via Bitcoin within 30 minutes.
So you’re telling me in a day and age where Twitter can make or break someone Anonymous Hackers Hacked Americas most powerful companies and rich people accounts and only used the “limited access” they had to scam for bitcoin? Which just so happens to be “untraceable” funds?
Ya Im not buying it. 1st of all: Its a American Presidential election year and if you hacked any Presidential accounts running for the highest office in the land you would not just use it to scam for bitcoin. A lot of people if they had access to these accounts would troll the hell out of America. My evidence for this theory is look at what happened to Trumps account. A Twitter employee who was fired before he left used his access to delete Trumps account before it was restored for like 5 minutes. He did not use it to scam for bitcoin.
One tweet can make or break the stock market. Your company or your reputation. And you use it to scam for bitcoin. Ya okay. Yet at the same time the untraceable funds that they successfully scammed out of people is going somewhere. My guess is to the Breakaway Civilization thats being built by these billionaires like Elon Musk, Bill Gates, and Warren Buffet. Musk especially has had a lot of success with his Rocket technology.
Edit: Why is this post instantly at 0 the moment I posted? I get shit for bringing politics into this sub yet I post a real conspiracy theory and instantly downvoted to 0 never to see “rising”.

Crypto Banking Wars: Can Non-Custodial Crypto Wallets Ever Replace Banks?

Crypto Banking Wars: Can Non-Custodial Crypto Wallets Ever Replace Banks?
Can they overcome the product limitations of blockchain and deliver the world-class experience that consumers expect?
https://reddit.com/link/i8ewbx/video/ojkc6c9a1lg51/player
This is the second part of Crypto Banking Wars — a new series that examines what crypto-native company is most likely to become the bank of the future. Who is best positioned to reach mainstream adoption in consumer finance?
---
While crypto allows the world to get rid of banks, a bank will still very much be necessary for this very powerful technology to reach the masses. As we laid out in our previous series, Crypto-Powered, we believe companies that build with blockchain at their core will have the best shot at winning the broader consumer finance market. We hope it will be us at Genesis Block, but we aren’t the only game in town.
So this series explores the entire crypto landscape and tries to answer the question, which crypto company is most likely to become the bank of the future?
In our last episode, we offered an in-depth analysis of big crypto exchanges like Coinbase & Binance. Today we’re analyzing non-custodial crypto wallets. These are products where only the user can touch or move funds. Not even the company or developer who built the application can access, control, or stop funds from being moved. These apps allow users to truly become their own bank.
We’ve talked a little about this before. This group of companies is nowhere near the same level of threat as the biggest crypto exchanges. However, this group really understands DeFi and the magic it can bring. This class of products is heavily engineer-driven and at the bleeding-edge of DeFi innovation. These products are certainly worth discussing. Okay, let’s dive in.

Users & Audience

These non-custodial crypto wallets are especially popular among the most hardcore blockchain nerds and crypto cypherpunks.
“Not your keys, not your coins.”
This meme is endlessly repeated among longtime crypto hodlers. If you’re not in complete control of your crypto (i.e. using non-custodial wallets), then it’s not really your crypto. There has always been a close connection between libertarianism & cryptocurrency. This type of user wants to be in absolute control of their money and become their own bank.
In addition to the experienced crypto geeks, for some people, these products will mean the difference between life and death. Imagine a refugee family that wants to safely protect their years of hard work — their life savings — as they travel across borders. Carrying cash could put their safety or money at risk. A few years ago I spent time in Greece at refugee camps — I know first-hand this is a real use-case.

Or imagine a family living under an authoritarian regime — afraid that their corrupt or oppressive government will seize their assets (or devalue their savings via hyperinflation). Citizens in these countries cannot risk putting their money in centralized banks or under their mattresses. They must become their own bank.
These are the common use-cases and users for non-custodial wallets.

Products in Market

Let’s do a quick round-up of some of the more popular products already in the market.
Web/Desktop The most popular web wallet is MetaMask. Though it doesn’t have any specific integration with DeFi protocols yet, it has more than a million users (which is a lot in crypto land!). Web wallets that are more deeply integrated with DeFi include InstaDapp, Zerion, DeFi Saver, Zapper, and MyCrypto (disclosure: I’m an investor and a big fan of Taylor). For the mass market, mobile will be a much more important form-factor. I don’t view these web products as much of a threat to Genesis Block.

Mobile The more serious threats to Genesis Block are the mobile products that (A) are leveraging some of the powerful DeFi protocols and (B) abstracting away a lot of the blockchain/DeFi UX complexity. While none get close to us on (B), the products attempting this are Argent and Dharma. To the extent they can, both are trying to make interacting with blockchain technology as simple as possible.
A few of the bigger exchanges have also entered this mobile non-custodial market. Coinbase has Wallet (via Cipher Browser acquisition). Binance has Trust Wallet (also via acquisition). And speaking of acquisitions, MyCrypto acquired Ambo, which is a solid product and has brought MyCrypto into the mobile space. Others worth mentioning include Rainbow — well-designed and built by a small indy-team with strong DeFi experience (former Balance team). And ZenGo which has a cool feature around keyless security (their CEO is a friend).
There are dozens of other mobile crypto wallets that do very little beyond showing your balances. They are not serious threats.

Hardware Wallets Holding crypto on your own hardware wallet is widely considered to be “best practice” from a security standpoint. The most popular hardware wallets are Ledger, Trezor, and KeepKey (by our friends at ShapeShift). Ledger Nano X is the only product that has Bluetooth — thus, the only one that can connect to a mobile app. While exciting and innovative, these hardware wallets are not yet integrated with any DeFi protocols.

Strengths

Let’s take a look at some of the strengths with non-custodial products.
  1. Regulatory arbitrage Because these products are “non-custodial”, they are able to avoid the regulatory burdens that centralized, custodial products must deal with (KYC/AML/MTL/etc). This is a strong practical benefit for a bootstrapped startup/buildedeveloper. Though it’s unclear how long this advantage lasts as products reach wider audiences and increased scrutiny.
  2. User Privacy Because of the regulatory arbitrage mentioned above, users do not need to complete onerous KYC requirements. For example, there’s no friction around selfies, government-issued IDs, SSNs, etc. Users can preserve much of their privacy and they don’t need to worry about their sensitive information being hacked, compromised, or leaked.
  3. Absolute control & custody This is really one of the great promises of crypto — users can become their own bank. Users can be in full control of their money. And they don’t need to bury it underground or hide it under a mattress. No dependence, reliance or trust in any third parties. Only the user herself can access and unlock the money.

Weaknesses

Now let’s examine some of the weaknesses.
  1. Knowledge & Education Most non-custodial products do not abstract away any of the blockchain complexity. In fact, they often expose more of it because the most loyal users are crypto geeks. Imagine how an average, non-crypto user feels when she starts seeing words like seed phrases, public & private keys, gas limits, transaction fees, blockchain explorers, hex addresses, and confirmation times. There is a lot for a user to learn and become educated on. That’s friction. The learning curve is very high and will always be a major blocker for adoption. We’ve talked about this in our Spreading Crypto series — to reach the masses, the crypto stuff needs to be in the background.
  2. User Experience It is currently impossible to create a smooth and performant user experience in non-custodial wallets or decentralized applications. Any interaction that requires a blockchain transaction will feel sluggish and slow. We built a messaging app on Ethereum and presented it at DevCon3 in Cancun. The technical constraints of blockchain technology were crushing to the user experience. We simply couldn’t create the real-time, modern messaging experience that users have come to expect from similar apps like Slack or WhatsApp. Until blockchains are closer in speed to web servers (which will be difficult given their decentralized nature), dApps will never be able to create the smooth user experience that the masses expect.
  3. Product Limitations Most non-custodial wallets today are based on Ethereum smart contracts. That means they are severely limited with the assets that they can support (only erc-20 tokens). Unless through synthetic assets (similar to Abra), these wallets cannot support massively popular assets like Bitcoin, XRP, Cardano, Litecoin, EOS, Tezos, Stellar, Cosmos, or countless others. There are exciting projects like tBTC trying to bring Bitcoin to Ethereum — but these experiments are still very, very early. Ethereum-based smart contract wallets are missing a huge part of the crypto-asset universe.
  4. Technical Complexity While developers are able to avoid a lot of regulatory complexity (see Strengths above), they are replacing it with increased technical complexity. Most non-custodial wallets are entirely dependent on smart contract technology which is still very experimental and early in development (see Insurance section of this DeFi use-cases post). Major bugs and major hacks do happen. Even recently, it was discovered that Argent had a “high severity vulnerability.” Fortunately, Argent fixed it and their users didn’t lose funds. The tools, frameworks, and best practices around smart contract technology are all still being established. Things can still easily go wrong, and they do.
  5. Loss of Funds Risk Beyond the technical risks mentioned above, with non-custodial wallets, it’s very easy for users to make mistakes. There is no “Forgot Password.” There is no customer support agent you can ping. There is no company behind it that can make you whole if you make a mistake and lose your money. You are on your own, just as CZ suggests. One wrong move and your money is all gone. If you lose your private key, there is no way to recover your funds. There are some new developments around social recovery, but that’s all still very experimental. This just isn’t the type of customer support experience people are used to. And it’s not a risk that most are willing to take.
  6. Integration with Fiat & Traditional Finance In today’s world, it’s still very hard to use crypto for daily spending (see Payments in our DeFi use-cases post). Hopefully, that will all change someday. In the meantime, if any of these non-custodial products hope to win in the broader consumer finance market, they will undoubtedly need to integrate with the legacy financial world — they need onramps (fiat-to-crypto deposit methods) and offramps (crypto-to-fiat withdraw/spend methods). As much as crypto-fanatics hate hearing it, you can’t expect people to jump headfirst into the new world unless there is a smooth transition, unless there are bridge technologies that help them arrive. This is why these fiat integrations are so important. Examples might be allowing ACH/Wire deposits (eg. via Plaid) or launching a debit card program for spend/withdraw. These fiat integrations are essential if the aim is to become the bank of the future. Doing any of this compliantly will require strong KYC/AML. So to achieve this use-case — integrating with traditional finance —all of the Strengths we mentioned above are nullified. There are no longer regulatory benefits. There are no longer privacy benefits (users need to upload KYC documents, etc). And users are no longer in complete control of their money.

Wrap Up

One of the great powers of crypto is that we no longer depend on banks. Anyone can store their wealth and have absolute control of their money. That’s made possible with these non-custodial wallets. It’s a wonderful thing.
I believe that the most knowledgeable and experienced crypto people (including myself) will always be active users of these applications. And as mentioned in this post, there will certainly be circumstances where these apps will be essential & even life-saving.
However, I do not believe this category of product is a major threat to Genesis Block to becoming the bank of the future.
They won’t win in the broader consumer finance market — mostly because I don’t believe that’s their target audience. These applications simply cannot produce the type of product experience that the masses require, want, or expect. The Weaknesses I’ve outlined above are just too overwhelming. The friction for mass-market consumers is just too much.

The winning bank will be focused on solving real user problems and meeting user needs. Not slowed down by rigid idealism like censorship-resistance and absolute decentralization, as it is with most non-custodial wallets. The winning bank will be a world-class product that’s smooth, performant, and accessible. Not sluggish and slow, as it is with most non-custodial wallets. The winning bank will be one where blockchain & crypto is mostly invisible to end-users. Not front-and-center as it is with non-custodial wallets. The winning bank will be one managed and run by professionals who know exactly what they’re doing. Not DIY (Do It Yourself), as it is with non-custodial wallets.
So are these non-custodial wallets a threat to Genesis Block in winning the broader consumer finance market, and becoming the bank of the future?
No. They are designed for a very different audience.
