Yes exactly.

"This is not necessarily a flaw in technology". When is the last time you needed to debug the contract when you buy coffee?

Why would you need to involve a smart contract to buy coffee?

My suggestion is: "grow up". All of human society is based on trust, and it works just fine and has for centuries. Who would even want to live in a trust less society? That sounds like hell.

I might trust someone enough to give them $20. I might not trust someone enough to enter my credit card details on their webpage.

That's why we have things like paypal and temporary virtual credit cards.

Many kinds of fraud attack the fallible human element, not technology. And blockchains cannot change that, as you can see with a glance at crypto news.

Blockchain is a perfect example, how tech folks want resolve humanitarians problems/issues with _tech_ solution. (Spoiler) It doesn't work

Actually, it is the SV crowd who needs to prove it is possible. :-)

Bitcoin is still more expensive than the banking system among first-world countries. How much can it be worth to send money to third-world countries of no banks are willing to set up there?

where are you getting these $1 international wire transfers? Sign me up!

SEPA transfers cost €0, which (still) is less than $1.

It amazes me how polarizing blockchain and cryptocurrency is. It is to black/white, love/hate. I really don't ever remember a technology that has created such a visceral reaction from people. I personally, believe there is a quite novel concept behind the trust-less consensus mechanisms. It amazes me that computers can come to an agreement in a hostile environment--fully decentralized. How that is put to use in pract…

There is no baby. The technology does not solve technical problems that havent been solved better. The only thing bchains does is give ppl with a lot of money to become stakeholders, the possibility to comodify even more parts of the internet. Thats the only upside of the technology, scam ppl for their money. https://www.stephendiehl.com/blog/against-crypto.html https://web3isgoinggreat.com/

Let's catch some low hanging fruit:

"blockchains can’t do anything against ... plain old typos in a coin transfer."

It is difficult to use properly crafted software and form a tx to a non-existent address on Bitcoin. It is not impossible, but not easy. The typical consumer is not meant to use layer-1 finance tools in any digital domain, modern, traditional, or blockchain based. Its not that hard to conceive of Bitcoin banks which have the same protections whilst offering currency sovereignty impossible in status quo finance.

https://www.reddit.com/r/Bitcoin/comments/26s1i5/can_you_los...

"However, in the world of blockchain there is no human supervisory authority."

There certainly are. One of the biggest hacks in history was reverted by human supervisory authority and community migration. This is an extremely unlikely method to help individuals who make some any mistakes on layer-1, however.

"The absolutely perverted energy usage in times of climate change is only one of those (this is mainly caused by proof-of-work, still used by all relevant public blockchains, and general inefficiency)."

This is a 'using energy bad' argument. With this logic we can also write off automobiles, smart-phones, artificial intelligence, hamburgers; if you do not quantify the value vs. the cost you cannot make an argument. Crypto skeptics are usually incapable of steelmanning the value proposition of crypto and make circular arguments like "crypto is not valuable because it uses so much energy," or appeals to their own ignorance.

You can't say Bitcoin is inefficient if you don't understand (or demonstrate that you understand) what it does. Somehow skeptics believe the proper response to pointing this out is to retort "I know what Bitcoin does, it uses energy to promote gambling!" That is not the response of a tech literate critic.

"this is mainly caused by proof-of-work, still used by all relevant public blockchains, and general inefficiency"

Proof of work is intensely 'out of style' even in the crypto space and sans Bitcoin and its much smaller forks (which almost invariably use mere fractions of Bitcoin's energy) there are only a few new, layer-1, relevant projects sticking to proof of work. Equating the number of tokens which exist on smart contract languages to the amount of energy used by proof of work is deceptive.

"(By the way: some of the advantages promised by blockchains, but without the nonsense, is implemented by Merkle trees 9. They already exist since 1979 and blockchains build on their technology. But please don’t also start trying to use Merkle trees for stuff it’s not useful for.)"

This is nonsense. It's like saying you have all the advantages of a cart or carriage by simply removing everything but the wheels.

"The main objective of blockchain is to decentralize trust and consent (even that it doesn’t do well, as explained"

This was not explained (you only need read a few paragraphs to prove this), and the author failed to state the view they are claiming to lampoon therefore have not demonstrated they understand what they are critiquing.

Let's acknowledge what the blog post gets correct:

There was, and still is to a lesser extent, an epidemic of trying to solve problems by engineering a blockchain solution. The absolute culling of anything spurious from the last market cycle has greatly decreased those endeavors and most money is in tokens on existing layer-1 protocols at this point. Skeptics and believers alike appreciate that mentality being ousted. Decentralizing services doesn't require a new chain for every new use innovation. Most of the important decentralization can be done off chain since most data isn't so important as Bitcoin account balances.

There is a large number of speculative 'scams,' or more realistically failed projects up-selling their potential. The likelihood of one's success investing in crypto without having done significant research or access to a trusted person who has is low. If a team has found genuine innovation the messaging around it will immediately be co-opted competent and incompetent, honest and malicious teams. You cannot determine which teams are competent and honest from their messaging alone, it takes digging. It is not a welcome or recommended place for anyone who cannot do and understand the results of serious digging.

Take it from someone who believes in the value of blockchain tech and has undoubtedly spent more time than the author listening to other 'believers:' most people bullish on crypto share the same valid complaints the skeptics make (this author makes all the cliche mistakes on top of the valid ones).

Not only that, but those serious in the space welcome critiques of the technology. Blog posts like this which are largely fueled by emotion and ignorance are denounced by dogmatic believers and scammers for bad reasons, but they are also ignored by honest believers for good reasons. Honest believers are receptive to competent feedback but this blog post is more of the same ignorance.

Nothing is stopping a peer-to-peer network from having a central database administered by the a randomly selected group of peers, for example. The bigger issues in pure decentralized and distributed networks in finance are around KYC/CFT etc. Who ensures compliance if there is no control about flow of funds, for example.

What you are suggesting sounds like a consensus mechanism. How do you safely choose which peers to assign this responsibility? How do you ensure it is resistant to a Sybil attack? Suddenly the answers begin to look a lot like Proof of Work or Proof of Stake.

The answer could or could not look like that. In practice people have done this many times throughout history totally without blockchains (or computers) for that matter (e.g., money transfer systems, exchanges, etc.).

Blockchain is just a decentralized ledger of transactions. A cryptocurrency is an implementation of digital currency using a blockchain. Blaming blockchain for not having fraud prevention tech is like blaming TCP/IP stack for delivering a scam email to your inbox. This is a problem to be solved in a higher layer, which we're seemingly nowhere near as we're still just trying to get blockchain to scale efficiently.

Correct, crypto is great when you need an append only database with no root password.

Outside of that use case crypto is a speculative investment vehicle. Maybe BTC will replace gold as a store of value. But that is just speculation.

I was able to buy a tshirt I wanted using Ethereum as the only two options were PayPal (which is blocked from use in my country) and crypto.

I was also able to donate money to Ukrania in war literally in a Sunday night in 30 seconds, again with Ethereum.

Yeah, "dangerous nonsense".

You could always use the crypto currency as the store of value there, just as people did with MPesa. You don't necessarily ever have to convert it to a local currency.

MPesa doesn't store your money in some kind of private currency with a fluctuating value. If you're thinking of it as storing "minutes" as some American cellphone providers would, that's not right.

You deposit and withdraw Kenyan Shillings, or your local equivalent, just as if it were a shilling-denominated bank account.
