> availability of "secured" goods What do you mean by that? Backing?

By that I mean not easy to steal by anyone at gunpoint. The point is that money is not wealth. Wealth is the ability to consume goods and services. If you got stranded on a deserted island with a suitcase full of millions you'd still live in extreme poverty despite all your millions. Therefore securing crypto-currencies doesn't replace the need for securing actual wealth. On the contrary, it's an extra cost that its…

Note that should you be rescued the suit case full of millions will still worth millions.

The suitcase, stuffed with medium of exchange, holds value across time.

This is the key concept to understand the issue at hand.

For a medium of exchange to become useful, it must first become able to hold value, preferably long term, months/years.

The only way an asset can do that, if there is demand to hold the asset for long durations, committed long term investors.

Bitcoin is an experiment in bootstrapping a neutral money system from scratch.

If you look at bitcoins money velocity, it’s much closer to M2, than M1. Thus comparing it to investment assets, or bonds, is much more relevant today than to payment systems. It’s a store of value for now, maybe a little speculative, sure.

Once it grows large enough and value becomes more stable, it can become a decent medium of exchange then.

This implies market capitalisation in many trillions, and if it proves to be successful: displacement of many other store of value. Negative yield bonds, gold. Maybe even real estate and rental yields on that are actually negative in real terms in many markets. We will see.

As such it would represents a cloud economy of sorts with large amounts of wealth stored in it, trillions of dollars. That would require a correspondingly sizeable security budget to protect.

Finally and Thank Goodness. I have been so depressed lately listening to all the "crypto-haters" bash something "they don't see a need for" that we actually need very desperately that it was really messing with my head. Of course, you don't see the need...you either aren't actually looking at the pain and high costs those on the outside are forced to endure or you just don't care. Finally someone in an actual position to know has written a piece that isn't hampered by their bias. He doesn't run a FinServices company for oldsters or pretend that BTC is worthless while being a part of a group of companies using XRP for years.

Thank You, Thank You, Thank You

I'll just stick with my "innocent until proven guilty" opinion. Taking the most outlandish route possible to smear someones name seems rather unhealthy for everyone. There's no precedence for someone pulling off a huge digital scam and failing to cash out because they forgot their password. Could it happen? Sure, there aren't many things outside of the realm of possibilities when you're tasked with proving a negative. Lucky for us, that isn't the responsibility placed on most anyone in social situations and definitely not for criminal accusations in court.

All NFTs are is a token on a blockchain. People might decide that having it let's you do other things, but that's all it is really. That's not being taken away from anyone. It's up to the organization or society or code written in smart contracts whether they want to honor, and how much they honor, the promises made for having possession of that NFT. It's really no different than any other organization out there for…

It seems like, whenever there is an issue with the representations of blockchain the answer is to ignore the blockchain. (Shoot, our smart contract was a little too limited for the service we want to offer “Hey everyone don’t use that NFT!”) Where as a traditional database the answer is to fix the database or code. I look at any process involving NFTs and have to wonder how they aren’t more easily and cheaply accompl…

There are ways to make upgradeable smart contracts but it wasn't really formalized until recently (there's now open contracts you can import into your projects to enable upgrades).

Additionally, a lot of the community are against upgradeable contracts because they theoretically can be upgraded to something totally different, and they prefer immutability, with all its potential warts. Some projects use upgradeable contracts and don't have to do what Premint did, and some people don't.

But regardless, if you're going to offer an organizational service that's not on the blockchain, then inherently, by definition, it can't be strictly enforced just by the presence of an NFT, because people aren't computers and their physical actions aren't guaranteed to happen by lines of code like a computer program can (at least not yet).

Tickets for a concert were a meatspace analogy, not me arguing to put all tickets on the blockchain. One difference, though, is the NFT 'ticket' can be proven for any organization that wants to incorporate it, without a prior agreement or API access created by the original organization. Like I know some NFT projects allow people who have NFTs from other specific projects in their wallets to have early access in their own projects, or grant access to private Discord rooms, or let them into events, etc. and it can be granted via software, without people checking or verifying anything.

Yes a REST API and a centralized database can provide that, but not if that organization goes defunct.

As an example from my own history, there's a game I worked on once that the company once debated on buying servers to host the multiplayer aspects of it, but eventually I just incorporated the general async turn based api of Apple's for the game. The company went defunct not even six months later. If we had gone the server route, the game would have been unplayable as soon as the company folded, but since we used the general protocol provided by the platform, the game was playable for many years afterwards (might still, I haven't checked in a while).

That's a very real (to me, anyway) benefit of building on a blockchain. As long as the blockchain platform is still up, those smart contracts can still be used, and its support doesn't have to be constantly justified by the parent company / count on the company not going out of business to keep running. Like Nintendo is getting rid of its Wii and 3DS shops here in a few months because they can't justify keeping it up. If the blockchain existed then and those things were stored on there (like files are stored on IPFS or Arweave for web3 today) they'd still be accessible without any continued expenses from Nintendo.

Right now I'm having to decide which of my digital games I need to make sure are downloaded and on my device before I lose the opportunity to redownload in a few months (technically I can hack the device and download stuff from torrents, but I'd rather not have to do that for a while, if ever).

Another benefit, to me, is similar and legacy related. Like my Facebook profile, website, games, journals, etc, when I die, all go away the instant that Facebook stops being a thing, and more importantly when I stop paying for web servers or cloud computing. My SO already made it pretty clear they're not really going to do anything to perpetuate them, so if I want those things to exist and be available I'll need to find something that can withstand not actively paying AWS, Azure, DigitalOcean, etc. to keep it going. Putting these things onto the blockchain would allow for that, and at the very least will outlive anything put onto cloud services, and possibly even the current crop of social media websites (definitely a few of them, maybe not all of them).

Some things I worked on are probably also circulating in some torrents of Flash games or console games also, but a lot of it isn't. And I have some physical copies of things I've worked on also (a lot of board game prototypes, some journals, etc), but I have a feeling a lot of that is just getting thrown away not too long after I die unless I something of mine becomes a big hit, maybe not even then.

You might not personally care about these things, but other people do. Or at least will once the infrastructure and supporting software is built out more.

So what? If the pollution is the problem, government should tax the externalities through a Pigovian tax. In the EU we have a functioning carbon cap, and as such mining is less profitable here. https://ec.europa.eu/clima/eu-action/eu-emissions-trading-sy... But the US will hear none of it: https://www.youtube.com/watch?v=MondapIjAAM

I think you pointed out the problem yourself. Bitcoin and pollution don't care about borders, unless you get every country in the world to pass such a tax the miners will just move to wherever they can get away with not paying it.

I agree. But lawmakers would have a double standard if they imposed such a tax, but only on Bitcoin miners.

Too bad power corrupts. All fiat currencies so far keep devaluing. If governments want to spend more than the rest of the economy, they should finance it via taxation, not inflation, which erodes people's savings.

Funny how inflation numbers just dropped which show it still running hot and bitcoin started immediately tanking along with the stock market.

That is short-term. If BTC supply stays the same while fiat currency keeps inflating, and if people will want the same exposure to BTC, then the price of BTC will increase with the amount of fiat in existence.

How is crypto any better at doing this than say, Western Union? Ultimately, as someone who finds blockchain technology really cool, what I struggle with is, in which scenarios is blockchain better than Postgres?

I agree that anything that can be done with a blockchain can technically be done with a database. But the practical challenge comes down to coordination problems. With blockchains you get credibly neutrality out of the box. Different developers are comfortable building inside a shared execution environment. If Western Union built a smart contract execution system, you'd have a much, much harder time convincing develo…

This is totally correct and something that devs on HN seem to struggle to understand. There are many theories as to why, but it is an unending source of amusement.

I'm not sure what you mean by "the most outlandish route possible to smear someones name". I fail to see why me asserting that not spending the coins isn't strong evidence about Satoshi's motivations is some how a smear or trying to assign guilt?

The entire conversation started because someone pointed out that just because Satoshi said something doesn't mean it has to be true (although they made that point in a rude way.)

The vibe I am getting from your responses is: 'satoshi is a saint, everything he said has to be true, and any attempt to point out that we have little evidence about Satoshi's character is a baseless smear.'

I am sure that is an inaccurate and unfair characterization of what you are trying to see, so please correct me as to where I have it wrong.

And it is fine to build systems with trusted parties on top of a permissionless network. The article cites USDC which does this, it is one of many applications users can choose to transact with. Attempting to bake reversibility into the protocol would lead to a tightly permissioned system with only a few trusted authorities. A loose analogy might be the internet, which aims to be a decentralized global protocol that…

If you build a system with trusted parties, you no longer need to build it on top of a permissionless network. If permissionless networks were zero-cost and had no downsides, it wouldn't matter. But in fact, they are incredibly expensive and complex compared to conventional systems (like relational databases), and have serious downsides. Once you need a trusted party, there's no way to justify the permissionless netw…

Well, I can think of a few reasons: facilitating transactions with other parties on the permissionless network, promoting public verifiability of your system, utilizing the tools and utilities available for public blockchains, requiring your data to be available even after you stop paying your hosting provider, avoiding the hassle of building your own payment on-ramps, etc.

> easier/cheaper hashing actually doesn't work -- the yield curve in bitcoin mining is there for a reason, and without it, I doubt PoW would fly.

And yet there are numerous non-SHA256 proof-of-work systems that have worked (pun intended) just fine while having lower energy requirements.

> Reductio ad absurdum: If it doesn't remain dominant, then it has no use case, as it's a lousy investment instrument. If the above goes throw for bitcoin, then, a fortirori, the same reductio can also apply to any other PoW coin.

This presupposes that all PoW coins have the same properties - never mind that pretty much every cryptocurrency created since Bitcoin has had "do it faster and cheaper than Bitcoin" as an implicit if not explicit goal.

> And don't get me started on PoS -- it's literally just an MLM you can buy into.

The people who say this are the same people who know next to nothing about PoS.

> I remember the nineties well -- relatives would go to China and come back with armfuls of factory-pressed CDs and DVDs. Anything you wanted. Clean and new-in-box. That went away because of IP protection baked into trade agreements.

It went away because now you can buy knockoffs on AliExpress instead of relying on relatives in China.

> And before you say 'BitTorrent', please remember, the analogy is _factory_ piracy

Nope. The equivalent to electronic money is electronic piracy. Moving the goalposts does not a good argument make.

> Bitcoin requires mining rigs, and these are large, physical assets, like factories, and this is unlikely to change.

Again: there are other PoW blockchains besides Bitcoin.

Even in Bitcoin's case, hashing ASICs don't have to be large; that's currently the most profitable approach, but mining can and would readily adapt. SHA256 is also a common enough algorithm outside of Bitcoin that hardware accelerators for it have ample non-Bitcoin usecases; you'd have a hard time blanket banning any and all SHA256 hashing unless you're willing to break password authentication for the vast majority of computers in a given jurisdiction, and you'd likewise have a hard time justifying the ban of hardware that makes password hashing faster (even if it just so happens to be capable of mining Bitcoin).

And if the farm's off-grid on solar? The energy provider would have zero visibility on that, and the helicopter flying around day in and day out would be far more ecologically destructive.

> Shoot it, then.

Good luck with that.

> Yes, but you can ban the sale of various things.

We're literally talking about a class of electronic currencies which do not give the slightest sliver of a rodent's anus whether there are laws prohibiting a given transaction. That strategy hasn't worked for IP infringement (despite your assertions), it hasn't worked for the drug trade, it didn't work for liquor trade during Prohibition, it's already starting to fail with the firearms trade in gun-restricting countries (thanks, 3D printers and hardware stores!)... there is zero reason to believe it would work for cryptocurrency.
