   > blockchains existed for decades before bitcoin did
That's absolutely not true. Bitcoin was the first blockchain like the ones we know today, the idea existed before but no one had implemented it in a decentralized way [0][1]. Bitcoin was also the first to solve the double spending problem. [2]

We had DHTs, we had blockchains, and double spending was solved at least 2 years before the bitcoin white paper.

Satoshi combined them together in a novel form, for sure, but it’s still largely useless.


We had linked lists of hashes which themselves referenced hash-tables, and we had a solution to the Byzantine Generals problem, but the bitcoin whitepaper combined them, and the combination of those two properties (not even tied to the consensus mechanism) is the thing people are talking about when they use the word "blockchain" now


> Satoshi combined them together in a novel form, for sure, but it’s still largely useless.


You seem to have a odd definition of “useless”.


It's only useful for speculation, scams, and drugs. What other utility does it have?


Sending money on the internet without a trusted third-party.

I think that's revolutionary.


There is a ton of trusted third parties involved. You're trusting:

- The KYC of your exchange, and any exchange in the coins path

- The wallet you're using

- The recipient to provide the correct address

- The exchange rate

And you're trusting all of that hasn't been tampered with, which involves even more trusted parties.

It requires an order of magnitude less trust to send cash in the mail. It's cheaper, too.


Maybe take others advice and stop commenting on this topic because everything you said is wrong. I’ll contradict all your points using specific personal examples of my usage.

I’ve bought Bitcoin many times without any KYC. In old days localbitcoins and these days ATMs in many countries.

There aren’t any “exchange in the coins path”. I’ve exchanged paper fiat currency at Starbucks, in a hotel lobby.

The wallets I use are open source 100%. In fact I’ve personally written a python script to manually generate a transaction to broadcast. There is no third party. only your operating system, the internet connection and the source code. In that particular case I was using NixOS linux and so my operating system was also open source. I also broadcast my transaction over the ToR network so my internet provider and the Bitcoin network has no visibility.

Now onto usefulness. By holding Bitcoin I’ve preserved and grown my wealth. But how has it been used practically. Lets see.

- yesterday I bought my lunch for my wife and I, $21 using by Bitpay debit card. I loaded the card 2 mins before with those dollars by sending Litecoin which was auto exchanged by Bitpay at exactly the current exchange rate and with no fee. I exchange Bitcoin for small amounts Litecoin periodically as Litecoin is fast and cheap to send for small payments. Savings vs Checking.

- Years ago I met an artist from Argentina on an internet forum. She was painting what I thought were nice paintings. She was selling professional prints of those. I sent her Bitcoin and she sent me the prints. I’ve framed them and they hang in my home. I get many compliments on them.

- I’ve hired a developer in Crimea to work on a security software and he was paid for his work in Bitcoin

- When my sister in law had a baby shower I bought all the gifts at Buy Buy Baby using a digital gift card purchased 30 mins earlier using Bitcoin.

I could actually go on and on and on. But clearly you don’t have experience or understanding of what you are discussing as you proposed sending cash in the mail, which I don’t know anyone who would do that.

Bitcoin is revolutionary and has a decent shot at bringing fiat government currencies to their knees so they are forced to act responsibly and not brr brr money print.


> Maybe take others advice and stop commenting on this topic because everything you said is wrong.

Oh lord.

> I’ve bought Bitcoin many times without any KYC. In old days localbitcoins and these days ATMs in many countries ... There aren’t any “exchange in the coins path”. I’ve exchanged paper fiat currency at Starbucks, in a hotel lobby.

Sure, ok. Now take just one tiny step forward. Think about what happens next. Those coins have extremely high odds of passing through a KYC system in the near future. That can, will, and frequently has been used to trace users who are dumb enough to think "I paid for bitcoin for cash, I'm now anonymous".

> The wallets I use are open source 100%.

And nothing nefarious has ever slipped into open source software, right? Do you have no idea what a supply chain attack is?

You use NPM, you really ought to.

> There is no third party. only your operating system, the internet connection and the source code.

And, of course, your OS and the internet can be trusted. This is a great example of the level of critical thinking cryptobros achieve.

> I also broadcast my transaction over the ToR network so my internet provider and the Bitcoin network has no visibility.

Ok, so you mitigate the announce IP, which is one of the least useful ways to do analysis. Cool.

> yesterday I bought my lunch for my wife and I, $21 using by Bitpay debit card. I loaded the card 2 mins before with those dollars by sending Litecoin ...

So it has objectively worse utility, UX, and more dependencies than fiat?

This is not a good example.

> Years ago I met an artist from Argentina on an internet forum. She was painting what I thought were nice paintings. She was selling professional prints of those. I sent her Bitcoin and she sent me the prints.

Ok. This is still not useful. Western Union, Paypal, SWIFT, all cheaper and in some cases faster.

> I’ve hired a developer in Crimea to work on a security software and he was paid for his work in Bitcoin

Protip: if someone is willing to be paid in bitcoin, they are not worth the bitcoin you're sending.

> When my sister in law had a baby shower I bought all the gifts at Buy Buy Baby using a digital gift card purchased 30 mins earlier using Bitcoin.

As above: "So it has objectively worse utility, UX, and more dependencies than fiat?"

> Bitcoin is revolutionary and has a decent shot at bringing fiat government currencies to their knees so they are forced to act responsibly and not brr brr money print.

You have absolutely no idea what a central bank does, do you? Well, I mean, you obviously think you do. But you really don't. A basic class on economics would do you a world of good.


Despite being nominally on your side in this discussion, the way you reply makes me actively wish I agreed with you less, because you are so hostile and abrasive.

This is no way to talk to other human beings.


A civilized discussion would certainly be much more productive. I can easy address the claims made and they are false.

If this poster actually knew how much experience I have with all the topics they profess such knowledge about I’d hope in that case they could be more mature.

Probably one of the must outrageous statements was to try and lecture me on the function of central banks. I’m intimately familiar with the US financial system and the function of central banks. I’ve extensively discussed Bitcoin with a very senior researcher of the Fed and was also directly involved in preparing private presentation to the ECB in Frankfurt. The central banks themselves are very concerned about how competitive Bitcoin is with fiat currency.

Bitcoin has more utility nowadays than dollar funds. It can be converted to almost any currency anywhere almost instantly and can be used by consumers with no friction via instant funded prepaid debit cards worldwide.

This poster brings up legacy payment systems that can’t even remotely compete with Bitcoin on the technical merits.


I keep thinking I should respond as you are so unbelievably wrong it really needs refuting these categorically false claims of yours.

However it’s seems doubtful you will even be willing to acknowledge your flawed understanding and perhaps even unlikely you will see my response give how HN works.


Any more background on how double spending was solved 2 years before bitcoin?


Sure. Whitepaper was released in 2008. Genesis block was in 2009.

In 2007 we had Combating Double-Spending Using Cooperative P2P Systems[0]. Prior to both the whitepaper and the genesis block, we had Distributed Double Spending Prevention[1].

These are all particular subsets of distributed consensus problems, which have been studied in the context of CS for at least 30+ years (Consensus in the Presence of Partial Synchrony[2]).

Thanks!

Do you have a pet theory on why bitcoin was the first such system to take off? Why not earlier?


I think it depends on what you consider to be the first such system.

The earliest ones I personally recall using were Liberty Reserve and E-Gold, which were basically fine, I guess. It was a good way to send money around with less eyes on it. Before that there were things like DigiCash, but I don't know much about that one. There was a whole bunch of random ones during the 90s, but most of them were ponzis and rugpulls (some things never change).

In my opinion, BTC took off in a way that others didn't for a bunch of reasons:

1) It was the first usable system that was decentralized, AFAIK. This is a pretty desirable characteristic, of course.

2) It had (and has) flaws, but there was no obvious means of it being a rug-pull or complete scam. E.g., it wasn't supposedly backed by gold/silver/whatever that didn't really exist.

3) You were able to get some bitcoin to use for 'free' by mining. Prior systems you had to buy into. The threshold to participate and profit was much lower.

4) The protocol is simple enough for those first few points to be trivial to verify.

5) It entered a sort of 'spiral' relationship with darknet markets and more general cybercrime. As those surged in popularity, the demand for bitcoin surged, which fueled interest in bitcoin, which fueled interested in markets, which.. etc.


the great recession of 2008


No.


Wow, that's a great point. I hadn't even thought to approach it like that.


I mean the whole comment is wrong and I mean not just a little, like straight misinformation.

> We had DHTs, we had blockchains, and double spending was solved at least 2 years before the bitcoin white paper.

- Bitcoin doesn't use DHTs.

- The term blockchain was coined after the Bitcoin white paper was published, to describe the mechanism used in Bitcoin.

- Bitcoin was the first system to solve the double spending problem in a decentralized way.

> Satoshi combined them together in a novel form, for sure, but it’s still largely useless.

The network is actively used. Just yesterday, there were 345K on chain Bitcoin transactions totaling a value of around 4 billion USD.


No-coiners are exhausting. Bitcoin triggers a deep psychological anxiety in some people and their reaction is to construct these defensive arguments in their heads about why Bitcoin is stupid, a scam, useless, etc.

If in another 10 years it continues it’s success and we have widespread point of sale usage and micropayments etc, and value is, maybe $200K/coin. Then these people might require some type of specialized psychological therapy to handle their disbelief.

On the other hand, Bitcoiners even if it crashes to zero somehow, will be saying at least we tried, oh well.

Bitcoin opinions are some type of strange personality litmus test. I find it very curious as the test result feels very unpredictable for me when applied to people I know well.


> No-coiners are exhausting.

More than naive cryptobros?

> Bitcoin triggers a deep psychological anxiety in some people and their reaction is to construct these defensive arguments in their heads about why Bitcoin is stupid, a scam, useless, etc.

It is obviously stupid, slow, and wasteful. Ignoring all the other problems with cryptocurrencies, just on those three axes ETH is superior.

> If in another 10 years it continues it’s success and we have widespread point of sale usage and micropayments etc, and value is, maybe $200K/coin. Then these people might require some type of specialized psychological therapy to handle their disbelief.

You love to monologue, huh?

> On the other hand, Bitcoiners even if it crashes to zero somehow, will be saying at least we tried, oh well.

A great sign of a moron is that they attach themselves to non-falsifiable ideas so they can't be wrong.

> Bitcoin opinions are some type of strange personality litmus test. I find it very curious as the test result feels very unpredictable for me when applied to people I know well.

It's very predictable. Is someone naive to the point of being borderline childlike? Wants to get-rich-quick? Hates the government? Bitcoin fan.


To be blunt, you have no idea of what you're talking about and should refrain from commenting on a topic you clearly don't understand. You're all over the place and clearly letting your emotions take over reason.


Another great point. Truly insightful.

This is the level of discourse adults experience from cryptobros, and it's why no-one except other cryptobros actually take you seriously.


You are the one making sexist comments, spreading misinformation and using insults... If you have concerns about Bitcoin or wish to express your personal dislike for it, there are certainly valid points to be made without resorting to fabrications or personal attacks.


> - Bitcoin doesn't use DHTs.

I didn't say it did. But the idea of distributing data in a P2P fashion is not novel.

> - The term blockchain was coined after the Bitcoin white paper was published, to describe the mechanism used in Bitcoin.

I'm not very interested in the particular etymology. The fundamental ideas of a blockchain, regardless of what you call it, had been laid out by multiple people years before the bitcoin whitepaper[0].

> - Bitcoin was the first system to solve the double spending problem in a decentralized way.

No, it wasn't[1][2].

> The network is actively used. Just yesterday, there were 345K on chain Bitcoin transactions totaling a value of around 4 billion USD.

..Ok? That's about the level of activity I would expect between speculation, scams, and drugs, sure.
