tl;dr: Nothing. But there are some big caveats to that. Sure, we already have tons of currency transactions going on digitally and on-line, but Bitcoin offers something that the centralized entities cannot, and these are (in no particular order): Unconfiscatable: Because nobody can take your bitcoins away from you unless you give away your keys. Regulation resistant: Because nobody can stop you from trading or transa…

None of your examples work as easily as you say. Unconfiscatable: a judge may order you to hand over your bitcoin, or face jail time for contempt of court etc. Regulation resistant: see above. Also, depends crucially on anonimity, which doesn't hold up either. Crime resitance: much worse than digital money, which is insured and much better protected by the state. Relative privacy: only works for btc-to-btc transactio…

> a judge may order you to hand over your bitcoin, or face jail time for contempt of court etc.

First the judge must establish that you indeed own the coins within reasonable doubt, which is hard enough on its own considering that Bitcoin doesn't store personal data. Then she must pry the keys from your brain, while proving within reasonable doubt that you haven't forgotten them. And if you have forgotten them, then she can't prove whether or not it's on purpose, so your sentence will likely be commuted. Because at that point there's a higher chance that it's the state committing a crime than you. Meanwhile if you had a bank account full of cash, all the bank would have to do is to freeze it, just like in Canada. You just can't do that with Bitcoin unless you keep the coins on a centralized exchange. And most smart owners don't.

As for bandits and robbers, they exist everywhere, but most of them won't know that you have crypto in the first place, because it can't be readily seen. And so it would be unreasonable of them to risk life in prison just for the off chance that you might own it. Cash or gold, on the other hand... Either way, that's not a reasonable argument against the unconfiscatableness of Bitcoin. It's certainly far less confiscatable than cash, digital or otherwise, and its unconfiscatableness is far superior to that of physical valuables. That's the point, and not that it's stored in some fictional fortress or No-Room (see Dune lore if you don't know what the latter is).

> Regulation resistant: see above. Also, depends crucially on anonimity, which doesn't hold up either.

The argument holds up just fine, because giving up your anonymity is voluntary and not required for Bitcoin to work. Digital cash, on the other hand... And even if the state suspects you of crossing their regulations, they would #1. have to know about it, which isn't likely, #2. they'd have to have good reason to believe you broke their regulations intentionally, and #3. they'd have to spend an enormous amount of resources to get all the evidence, and push the case, which means they'd more likely focus on bigger fish. But if they do spend all those resources on you, it increases the chance that you're living in a horrible surveillance state, and so your best course of action is really to move to a better place, and countries like that do exist. And so the argument still holds perfectly, that Bitcoin is indeed regulation resistant. The reason for that is because state actors (or criminals) cannot in any meaningful way stop transactions that go in and out of different jurisdictions, even if those states are adversarial to Bitcoin or not. In order for them to do that, they'd basically have to shut down the Internet entirely, and not even China does that!

Also please take note of the word resistant. As you may know that doesn't mean airtight or 100%. Most people willingly give up KYC information to central exchanges to trade it, for example. Well, then you voluntarily comply with regulation, so it still holds that it's coercion and crime resistant. And in giving up personal information, it can also be argued that you in fact increase crime resistance as a trade-off, so doing it isn't even a bad trade, say if you want to do it in order to trade on a centralized exchange!

> Crime resitance: much worse than digital money, which is insured and much better protected by the state.

Oh, so your state pays back money that has been robbed from you? Neat! :) Sorry for the sarcasm, but I really expected better from you... Where I'm from, state sanctioned insurance funds sadly only covers bankruptcy. With that said, insurance of self custodied coins is of course quite possible though completely voluntary. And as if that isn't enough, most exchanges also insure your crypto by default, thus voiding the latter half of your argument.

Even so, insurance is a completely different matter to crime! Because when it comes to crime, police everywhere are obliged to investigate any criminal theft of value, no matter if it's cash or otherwise. So I don't see how somehow owning crypto suddenly makes you any less protected by the state. If not, the New York couple who stole billions in crypto this year would be set free.

In fact, since the ledger is public and accessible to all, there is a really great argument for crypto owners being better protected than if they merely lost cash. Especially since you can stop criminals by publishing the ownership of your wallet to exchanges. The police are thus far more likely to catch crypto robbers than if you lost cash.

> Relative privacy: only works for btc-to-btc transactions, or if you spend significant effort.

The neat thing here is that you actually don't have to spend significant efforts to keep Bitcoin private, especially if you generate a new address for each new coin received or sent, which is pretty trivial within this technology. And it's only getting more secure with the Lightning Network. So in sum Bitcoin is moving towards becoming even more private and secure. Either way, nobody's forcing you to buy crypto on centralized exchanges. It's entirely possible to exchange it privately, and many do.

> Corruption resistance: maybe, since privacy is really bad.

Quite the opposite, privacy on Bitcoin is pretty good. Although central exchanges do store KYC data, they won't give it out nilly-willy. It's really up to you whether you want to sacrifice convenience for anonymity though. The same isn't true for most other payment methods, unless you are somehow able to get your hands on large amounts of cash without showing your ID at some point. Outside of that, there is of course a theoretical possibility of losing your privacy if you practise really poor operational security, such as transacting over unsecured channels on what you think is airport wifi.

But even though you keep your anonymity air tight, Bitcoin is still corruption resistant. It stays corruption resistant because the ledger is public, and because bad transactions can be flagged. Thus even though the exchanges or institutions might not know your name, you'll still be prevented from using the coins in your wallet if it's found that they are from illicit activity, thus incentivizing good behaviour. And so even though privacy is really good, it's still corruption resistant.

> the heyday of people using BTC for actual transactions I think has mostly gone.

So entire countries using it as legal tender doesn't impress you? Man, you're hard to please! As for El Salvador, nobody's forcing them to use the Chiva wallet. And afaik you can also transact with it with both through the legacy system and with the Lightning Network.

Fundamentally the transaction rate is limited by how much data you're willing to store. Bitcoin's 5tx/sec translates to ~5gb/month added to the blockchain - improving upon this requires either making the data stored per transaction smaller, increasing the blockchain growth rate, or moving transactions off-chain.

That’s true only if you care about storing historical data

When the balance of every address can only be calculated by executing the total transaction graph, as in Bitcoin, then you need to store the history.

If you have a solution for this that does not require trusting anyone, I'm sure that people would love to hear it.

> there is nothing here more than you can get with traditional database technology?

>seamlessly send value across jurisdictions I have money. How can I get some crypto? From a middleman. Need to pay fees. Then I send it to someone. Transaction fees. The receiver wants to buy groceries or pay kid's school fees, so they need to convert the crypto to money. Again fees. So lots of middlemen and fees are involved. And most of the time, One would need to provide full KYC and need to have a bank account to…

Please refrain from putting words in my mouth. I never said that Bitcoin doesn't have fees. Inventing arguments against things I never said is very uncool.

With that said, using Bitcoin to send value across jurisdictions is still seamless and far cheaper than most alternatives, except perhaps for some other cryptos...

As for using Bitcoin to pay for stuff, sure there are fees, but then there are also fees for using banking services, except more of them are conferred to the vendors and to other banking fees, thus making Bitcoin a pretty great alternative anyway. However it's not the fees alone that makes Bitcoin a preferred choice over banks. It's the whole package, of unconfiscatableness, cutting out middlemen, privacy, and so on, and I happen to think the small fee you pay for that package is a lot better than what you get with fiat. Either way, that doesn't take anything away from the fact that you can do a lot more with crypto than you can with transactions stored in a centralized database.

Blockchain technology helps you create applications without the need to have a trusted 3rd party.

What it solves?:

- Sending money from Alice to Bob without the need of a trusted party like Venmo/Paypal/Bank.

- Vehicle registration / House title deeds are maintained by the local government. A decentralized application can potentially mint an NFT (ERC-721) and maintain such a DB. (Although, the physical society would need to come with laws to tie up physical good's with NFT's)

- In today's Gaming Economy all the digital goods bought/earned are controlled by the company (Zynga/Roblox). A blockchain powered game will allow the owners to have actual control of the digital goods ( money - tokens, wearables - NFT's) bought/purchased that they can sell/exchange in the open market. Imagine buying a souvenir from Disney Land and then not being able to sell/exchange it.

The current state is, roughly: Government-backed contracts are ultimately enforced by litigation, which is judged by a judge, who is appointed and judged by the state government, who are appointed and judged by the governor, who is appointed and judged by democratic elections.

Of course there's room for improvement, what's silly is thinking a coal-powered linked list is an improvement :) You don't want true decentralization for state level activities such as voting. If it's truly decentralized and permission less, allowing anyone to control the ledger, your adversaries will take control. If you have to build a system that accounts for that, you rely on a central authority to switch you ove…

Again, Proof of Work is not the only consensus model for blockchains (and while I dislike PoW, it's worth noting that while there's a lot of "greenwashing", many mining farms have legitimately been moving towards using more renewable energy)

> There is no external trusted documentation that says what the intention of the code is. Working out what both parties intended a contract to mean and what it should mean, sometimes in contradiction of what it actually says is exactly what the legal system does. You can't evade the legal system by writing your contract in a different form. Weirdly I think this idea comes from thinking law is code when it isn't.

A judge is supposed to read the smart contract source code and determine the intent? The parties are frequently anonymous and have never interacted outside of the publication the smart contract to the blockchain and another party interacting with it. There is no basis for determining intent besides the code itself. Are you thinking that the contracts have analogs to legal contracts? Usually (exclusively?) they only m…

>A judge is supposed to read the smart contract source code and determine the intent?

If it's hard for a judge, it's presumably also hard for anyone using the smart contract.

>There is no basis for determining intent besides the code itself.

I'll bet you any frequently used contract has an associated website.

Basically, conducting your business on a blockchain doesn't exempt you from the law. You - the squishy human at the end of the transaction - are not on the blockchain, and neither is the author of any smart contract you might use. As long as the law recognizes blockchain assets as valid consideration in contracts, contract law trumps blockchain law.

Except with git repositories there's no built-in consensus mechanism, and we have the potential for a double spend. Say we're assuming the git repo includes gpg signing and users can make commits attesting that they've sent some amount of their balance to another user. John makes a commit saying he sends his entire balance to Alice. John pushes that to a central repository, and Alice gives him her house in return. Jo…

Still the Git concept works using a different trust model (i.e. repository maintainer).

That's github more than git, isn't it. Anyone can maintain their own fork of a repository. Much like with blockchain, it comes down to a community decision which one to accept as "canonical".

The difference is a lack of consensus at the protocol level for git. The network's only 'canonical' version of things is at the whim of the maintainer (who can also rewrite history)

The sole purpose of blockchain is to prevent double spending without a trusted party Other proposed applications are mostly dumb / misguided, like immutable storage, social network posts, etc, these can be done with hashing or digital signatures alone If you have a better way to avoid double spending than blockchain folks woukd get very excited. Traditional database can’t do that (requires a trusted party)

>The sole purpose of blockchain is to prevent double spending without a trusted party That is most accurate description of blockchain I have read. Unfortunately, the mechanism for that (Proof-of-work) is slow, expensive and planet destroying at scale. And while we may remove a trust provider third party, we aren't getting rid of centralization with blockchain anyway.

PoW is not needed at all its just a puzzle do "randomizes" who can write the next block. Its comically inefficient and p much the worst known working solution. Some BTC devs realized this and created Federated Byzantine Agreement (FBA) which used Byzantine Agreement rather than a puzzle to created the consensus and then federated the whole system to prevent 51%-like attacks.

Obviously if the peers work together with the goal to reach consensus based on fix rules it becames way more efficient. Only a few year after bitcoin this was already invented theoretically and shortly after build an went online 2012/13. It essentially depreciated PoW (and Bitcoin) long before all the BTC clones existed and even before ETH. People just tend to stick to "the first of something" and fight whatever comes after.

tl;dr The secret sauce of blockchain is not PoW, its a public state of a ledger that can be verified to be correct by anyone without trusting anyone simply by applying the rules of the system yourself.

Mm what ? As far as i know you dont' need a "exchange" but simply a wallet (which is a key and a bunch of passphrase) and an internet connection, and another person with the same thing willing to exchange. You may be in a pariah state but the system works because of mining all around the world, not just in your state.

Say you have 100 million Turkish lira, and suspect that Erdogan's terrible policies will reduce the value of that, so you want to buy bitcoin with it. How are you going to acquire BTC without access to an exchange (or some equivalent) that agrees to buy your lira? You could buy mining equipment and electricity of course, but then the state may crack down on your operation before you have a chance to recoup your inves…

At 100 milion you will have access to people you and I dont who know schemes better than bitcoin to buy massive foreign cureencies..

Such as simple as buying a property in london

And for that:

Blockchains are a tech for commons records among consenting parties. As a "database", it's really quite niche. But as a fundamental tech it's an advancement, because it lets you set up some basic rules and then know that the log henceforth doesn't need a designated custodian, and can accommodate many contributors. The surface area for indiscretion is reduced, and the chain doesn't need highly visible maintenance to stick around.

This quality also makes it actually pretty unsuitable for capitalism: capitalism premises enclosure of the commons through the enforcement of the state. It desires strong identity and legibility everywhere. So it becomes "pointless" by definition - a bad database - if the state or some other body is assumed in control. Thus the commonplace scenario of blockchains being a legitimizing veneer for scams has taken hold: actually using their best qualities is anti-capitalistic, but using them to obscure a scheme can be done if you tinker around with the financing enough so that you stay a step ahead of regulation.

But there is genuine activity, gradually increasing over time, through the contrasting role of blockchain stewardship. This starts with the role of miners in the technical substrate; and it proceeds towards more general ideas around governance and solving decentralized coordination problems. Markets often appear in the midst as a way of ranking things by price as well as by name or category, but markets aren't necessarily special. The speculative market does has a role in building up these ideas, though, because each time the tide goes out, those projects that have done the best at addressing coordination issues become survivors. There's a holistic element to the tech really working well that is just barely being touched upon.
