I would argue 99.99% of crypto and nfts are complete scams. But Blockchain is a change in how we manage and distribute data, and can remove centralization of power from humans that we would otherwise need to trust for managing autonomous systems like the data in a banks public ledger.
It’s also a misconception that some illicit players can take over a large enough Blockchain system.
The cost to run a 51% PoS attack on Ethereum, as of today, is $20 Billion
(current staked total of $40 Billion)… that is, $20 Billion, if you already had them. Buying that much of Ethereum, with an available liquidity of $670 Million… is just impossible, there is not enough on the market, simple as that. If you tried really hard, you could maybe convince some HODLers to part with some of their hoard for a high enough price… unless they decided to stake and try to stop you. How high would you want to go to prevent that? $200 Billion? $200 Trillion…?
Then after proving you can pull a 51% attack, the price would instantly crash down to $0. How much spare cash do you have to burn?
Let's do Bitcoin
Running a 51% PoW attack on Bitcoin, would mean either hijacking half of the current 400 Million TH/s hash rate, or adding your own 400 Million TH/s to the network. The most recent and cost effective mining hardware does about 250 TH/s for $8500 (plus power), so you’d only need 1.6 Million of those at a cost of above $13 Billion. Sounds easy, until you realize there are no 1.6 Million miners on sale. If you tried to buy those many, fat chance the manufacturer wouldn’t keep 50% of the production to themselves.
Then comes the kicker: on a network without smart contracts, you can only double-spend your own coins, or block others from spending theirs… for how long would you be able to keep that 51% attack, before people realized what was going on and just kicked you out of the network?
Trust is trust in the inability of anyone to successfully attack a financial system.
Blockchains are absolutely provable/accountable to everyone everywhere at any time, which central systems are not.
Oh, don’t get me wrong - the technology behind them is something we should be embracing more than we currently are. Being able to publicly have transactions out in the open is great, and ensuring that both parties have to authenticate on both their ends helps a ton in preventing stuff like fraud.
I just think cryptocurrencies and NFTs are squandering the blockchain and the tech behind it. There are a couple of cryptocurrencies that make sense because they have something backing it (which I just personally prefer straight-up, even with fiat money), but it’s otherwise pretty much all crypto follows Bitcoin’s trend, which in turn is more akin to a stock where it just… sort of arbitrarily goes up and down. NFTs as we currently know them, on the other hand, are just a huge scam through and through lol.
“Squandering” is a great description of what they’ve been used for. The only implementations I’ve seen thus far that seem genuinely useful are FileCoin and a few decentralized computing attempts like ICP (not Ethereum). I could see a potential niche use-case for NFTs to decentrally coordinate ownership of abstract properties like domain names, but speculative monkey jpegs ain’t it chief.
NFTs could also be used as ownership proofs of DRM protected stuff, like games, software, music, videos, books… no more “buying” an ebook until Amazon pulls it out of your “library”. Arguably any certificate is a kind of off-chain NFT, and vice versa, so using one or the other may become interchangeable depending on whether it should be made public or kept private.
Ethereum focuses on being a generic platform for DeFi services, so it’s logical that it has the largest amount of trashy attempts at reinventing the wheel. ICP I still haven’t found a real use for, and FileCoin storage costs are crazy high, way above most cloud solutions.
Could you describe a case example how that applies in practice?
Because yeah I understand that when we all have our own copy of the data someone can’t falsify all our independent copies but is data being tampered like that even the problem?
It’s a problem when you’re dealing with decentralized systems (read: Byzantines general probelm). If there’s no central authority, how do you verify the person actually has the money and isn’t lying / double spending?
Bitcoin is an example. A wallet is unique data (private key) that is stored only the users storage. That private key proves ownership of funds owned by a wallet address / hash. A wallet address has funds if someone with valid funds sent money to it. A person initially gets that data by mining, which is like spending computational power to solve a puzzle, in which solving also processes a set of transactions at the same time. This is like the process of minting, except anyone is allowed to mint. It also helps identify who the miners/minters are, since utilizing energy gives a signature (It’s really hard to hide using a megawatt of energy with a thousand computers, for example)
A use case is it allows people in war torn countries to consolidate their wealth digitally. Gold, for example, could easily be confiscated at the border, or the refugees currency could only have value in their country. Lebanese people had their money squandered by the banks and the government, because they were the central authority. In a system managed by people, over a long enough period of time, a bad actor will gain some control of the system. This effect is worse the more control is centralized.
It also means you couldn’t sanction other countries the way the America is doing to Russia’s banking system right now. I’m indifferent about that argument but maybe you think those sanctions are good in which case would be a point against decentralized currencies.
I think more interesting ideas in blockchain involve decentralizing ID. A microchip in the heart can both act like a smart watch by monitoring health data and represent a unique identity in a decentralized system by using the biometric information like a fingerprint scanner. With a secure decentralized way to establish identity, you can decentralize voting, and remove politicians from the political system
A microchip in the heart can […] remove politicians
I… think that would be a crime, even with a majority vote. 🤫
biometric information like a fingerprint scanner. With a secure decentralized way to establish identity
We already have that in most countries, it’s biometric national IDs and passports. Particularly in EU countries which issue biometric national IDs with secure personal certificates, we could implement direct democracy right now.
I personally envision a future where we use blockchain technology to create a new direct democracy party in which every member has a unique identifier and the blockchain ledger system used to track polling data. Every individual member of the party would have one vote in each poll at ever level (federal, state, regional, etc) - for every single thing that gets a vote, and the elected politician representing that party would be required to vote based on the polling data.
Everyone would have access to a copy of the ledger to confirm their votes are counted accurately, and they can review polling data to confirm their elected politicians are voting based on polling data, and the representative would be replaced if they do not adhere to the results
Why a party? You don’t need a party for direct democracy, just 1 person = 1 vote. Either vote yourself, or authorize someone you trust to vote in your name, be it for a time, or on a certain topic, or whatever, if you’re too busy to vote on every poll.
I’d love to see that happen, But it’s because America won’t switch to a direct democracy. Instead we have a Kleptocracy run by corporations and the 1% who have power over both parties in America. However if it were possible to create a third political party where every member of the party earns only one vote maybe it would give people power back over corporations. But it’s a pipe dream, I know it’ll never happen.
The problem I see with it being a third “political party”, is that it would still have to get past the gerrymandering, the FPTP, and the general issue of financing.
In representative democracies, that “representative” part is so often set up with extra hoops in a way that counters any attempt at direct democracy. It’s… a curious coincidence.

It’s a common misconception that blockchain gives trust. If you control a majority of nodes in a Blockchain system you decide what the truth is.
This opens the door for illicit players to manipulate things their way.
Lack of trust doesn’t replace trust.
Central, provable/accountable, trust is needed for financial systems to work.
Everything else is “Wild West”.
