Is the blockchain an interesting innovation, aside from cryptocurrencies ?

Submitted ⁨⁨1⁩ ⁨year⁩ ago⁩ by ⁨loaExMachina@sh.itjust.works⁩ to ⁨[deleted]⁩

For a long time, I thought of the blockchain as almost synonymous with cryptocurrencies, so as I saw stuff like “Odyssey” and “lbry” appearing and being “based on the blockchain”, my first thought was that it was another crypto scam. Then, I just got reminded of it and started looking more into it, and it just seemed like regular torrenting. For example, what’s the big innovation separating Odyssey from Peertube, which is also decentralized and also uses P2P? And what part of it does the blockchain really play, that couldn’t be done with regular P2P? More generally, and looking at the futur, does the blockchain offer new possibilities that the fediverse or pre-existing protocols don’t have?

Merkel Trees are fine, and are how things like “Git” keep track of different files (and how distributed hash tables and file-sharing often work).

Merkel Trees are trees-of-hashes, which the cryptocoin world wants us to believe go by the new name of ‘Blockchain’, but people familiar with comp. sci history know that they’re just flailing about making shit up.

Blockchain is an application of Merkel Trees. Merkel Trees have lots of good uses, but Blockchain doesn’t seem to have much use after 10+ years of experimentation.

  ETH has DNS. I would think the fediverse would like to see adoption of DNS that governments and big companies can’t mess with or take over with lots of cash.

  You seems to know what you’re talking about, have you heard of Juliana trees? Like trees based only on the keys, so searching for a key takes len(key) time.
  
  Bet there is an other name for it but I so remember like that and no web search says anything about it so I’m trying my luck here :-)

I thought it sounded interesting when it was new but the more I've learned, the more convinced I am that it's completely useless. I've never seen anything done on a blockchain that couldn't be done faster, cheaper, and more securely in a SQL database. Even the not-a-scam applications are ridiculous and fall apart upon examination. Blockchain as a definitive record of ownership? Absolutely not. There's no way to force a person to update a record. Lose your house in a bankruptcy? The sheriff on his way to evict you isn't going to care that you've got some NFT saying you still own the house. Anything involving contracts at all? If a court can't unilaterally update the blockchain record, then the record is unreliable. But if the government can unilaterally update a record, then you're not relying on community consensus and immutability in the first place.

Blockchain isn't useful for anything important, and it's not a logical choice for anything trivial aside from literally just playing with blockchain stuff for the sake of playing with blockchains. I think it's a dead-end technology.

  Once BTC hits enough halvening-cycles, the entire protocol doesn’t work anymore. Its more beneficial to fork the blockchain (and collect ~50 transaction fees), rather than work on the head (and only collect ~5 transaction fees).

    What’s wrong with that though? BTC handles forks just fine. Eventually one fork will win out and life will continue on as usual.
    
    The bigger issue this paper presents is that miners become incentivized to mine empty blocks. But can’t you just enforce a minimum transaction count on blocks?

Blockchain (simplified) is a giant excel spreadsheet that you can never edit, only add to. I struggle to think of any applications that is a benefit for, and even then append only databases would already do it better.

One of the benefits is supposed to be decentralization, but people tout that as a benefit for things like house deeds, or identification, or whatever. Imagine how massive an append only excel file of every house with every owner change etc etc included in it would be. Then we once again only have the people who can afford to store that much data storing it, and we are back to where we are now.

It doesn't really solve any problems, it just is a worse version of what already exists.

  Something about this comment didn’t seem right to me, so I did some quick math:
  
  There are approx 144,000,000 homes (incl apartments, etc) in the US. www.census.gov/quickfacts/fact/table/…/VET605221
  
  Assuming every home is sold 5 times on average, that’s 720,000,000 sale records/deeds.
  
  Existing blockchain implementations use IDs that are around 32 bits, or 4 bytes.
  
  A “home sales record” or deed on the blockchain needs to include the buyer and the time/date of sale (8 bytes), along with a cryptographic signature (4-16 bytes). The seller’s identity doesn’t need to be included because it’s always doing to be the previous owner.
  
  So each record is 16-28 bytes, and there are 720,000,000 records. If we go with 28bytes, it would take about 20GB to store all of the deeds for the US. A 500GB hard drive costs $20.

    You forget that the blockchain is all about not trusting some middle-man/site, so you need to stock that blockchain yourself, everyone needs to stock that blockchain.
    
    So multiply not only the cost, but also the ecological impact just buying all those drives.
    
    And that’s only for *US" housing (I didn’t get the timeframe you used to calculate it, is it for like year 2050? Old data stays forever.).

I find it to be an interesting solution looking for a problem. There could be many applications but I’ve yet to see one that blockchain could solve better than anything else that we already have, outside of crypto currencies.

Web3 is an interesting though experiment but I don’t see how it would work in real life. It would be extremely slow, data loss would be a daily occurrence and it would be a privacy/security nightmare.

    But you would still need an authority that can unilaterally make changes to these ownership records. People die, things get lost, stuff happens. So it can’t all be based on signing with private keys of individual persons. At that point: Why not run a central database of it all. It’s cheaper, more efficient and you could still publish a public record for traceability.
    
    I really don’t see any problem that Blockchain could solve better than other solutions. Except Cryptocurrency.

So Google, Amazon, Apple, and many other large companies in the IoT space are using a blockchain as a federated data store: github.com/…/distributed-compliance-ledger

It stores the data needed for Matter [ en.m.wikipedia.org/wiki/Matter_(standard) ] device attestation.

I think its an interesting use case on how entities that don’t particularly trust each other can operate a federated system. Accounts are linked to an identity out-of-band in order to have write permissions to the chain. When an account writes, all the readers of the chain have reasonable assurances of the author of that write. No company can inject false state as another company without that company’s guarded private key. All transactions are also auditable as an additional assurance the data isn’t undergoing a malicious act.

tl;dr; interesting use cases for tamper proof federated ledgers.

The value is in the forward signed, immutable ledger written by neutral consensus. This can take a lot of form and be the backbone of many types of applications (and already is used by large firms), the current market for direct public ledgers is a mess and I don’t generally agree with much of the last craze beyond the fundamentals needed to manage transfers, ownership and executions. The applications that will use these kinds of networks haven’t really been built yet.

    I can say of the top of my head the JPM and AMEX are running internal ledgers but there are many more, IBM and Accenture co-developed a system called Hyperledger which was given to the Linux Foundation. Its a tool kit for developing and deploying ledger applications primarily targeted at internal corps.
    
    One of the cases these are good for is an easier to manage rights and asset control systems than many products you would pay more for and with less futzing with IAM, LADP or AD.

    This is true, the fundamental of a blockchain is simply signed blocks of binary data. We can get into the debates on weather this can work in a public system like many groups are trying now, though I presume that that is not really what the poster is talking about since most public chains fundamentally rely on thier cryptocurrencies to to function, which for some is an argument as to why they can’t work.

    Blockchains come in many forms, the ones you are thinking of are what are called Proof of Work chains, these uses a kind of cryptographic race to secure thier data and use a TON of waste energy as a result. Def not a fan either.
    
    The growing popularity and interest in chains is around forms of Proof Of Stake, these use other internal protocol mechanisms to secure the network and work to run the cryptographic functions as efficiently as possible. Unsurprisingly the fastest blockchains are proof of stake and power wise are similar to traditional applications in utilization.
    
    You don’t need any of these networks if you don’t want to use them, fundamentally, they arent even networks, they are cryptographic messaging systems. How the data is sent and processed is incidental, you could work out a bitcoin block on pen and paper if you wanted. This concept has extended to a cryptographic tool called Zero Knowledge Proofs, these will be part of next generation identity verification systems and is a fundamental of the W3C standard around DiD, the whole point is for disconnected attestation.

    Forward signed, immutable ledger - a dataset that is written and logged at time of write and validated using cryptographic signatures of the creator of that data and the node of the network responsible for the data. public systems use incentive systems to ensure unbiased writes, private systems work more like your typical app server.
    
    neutral consensus - this is the p2p aspect, this is a bunch of unrelated actors promising to work toward an unrelated goal, in public systems this is done via some form of game theory, in private systems orgs working together have contract law and are more interested in the the controlled writing.
    
    How it can take a lot of forms. Most people are just familiar with what the general public refers to as cryptocurrency. These are ledgers managed on p2p networks with the aforementioned game theory based consensus system. However ledgers are not required to do this, a ledger and even a blockchain can work without fees or even energy wasting miners, in these cases its usually the cryptographic write and channel messaging they want (some of these are a step up from AWS’s messaging stack).
    
    Ledgers like this are used in many ways and used in large orgs around the world, what the public is angry at and what the technology is are very different things.

    A blockchain is like a special notebook that many people can write in. Once something is written, it cannot be changed, and everyone can check that it was written correctly. This notebook help different people or companies work together by writing down and sharing important information in a safe and secure way.
    
    Some people use these special notebooks to make digital money like Bitcoin. But it’s just way to use them. Companies also use these notebooks for other things, like making sure their business runs smoothly and securely.
    
    So, the blockchain is not just about digital money, but also a to help people and businesses work together safely and fairly.

    Cryptocurrency does work. It wasn’t so good at scaling or maintaining a stable price. Or converting between other currencies. Really, it was more of a speculative gambling or money laundering vehicle than a currency, but it can handle transactions. Both sides have to cryptographically sign the transaction (using their wallet’s private key); one side can’t just unilaterally decide that transactions happened and now it’s rich.

zero knowledge proofs, like those being deployed on blockchains recently, have the potential to be the killer app for this tech. Imagine you want a library card which requires proof of residence. With a zero-proof identity system, you could get your library card without revealing any personal info, like your name or address. Your wallets would simply prove to the library that you are a resident as credentialed by some local/state authority.

This also could have profound implications for the web like universal logins to web services, online privacy while still providing attribution, ownership and rights to digital content, copyright, etc.

So the actual tech behind could lead to some interesting ways to utilize it, but it’s admittedly squandered on cryptocurrencies and shitty NFT “art”.

Like, you could probably get rid of identity theft being an issue if you had unique tokens that would have your personal info like your legal name, birthdate, SSN, etc to ensure that it’s you and not somebody pretending to be you. Instead of entering in this info, you could just share the necessary tokens with the other party - so if a bank needed your info, for example, you could just give them the tokens containing the different info they need into their wallet. No idea how feasible that would be, but I do think there’s more actually creative and useful ways to utilize the blockchain tech versus just relegating it to shitcoins and ape art.

  What you’re describing kinda just sounds like ID cards or passwords… I mean, these can be stolen, falsified ot lost, but even assuming the “falsified” part is and remains impossible, couldn’t it be possible to obtain or duplicate someone’s token?

    From my understanding (and it could be wrong tbh, this is a bit out of my wheelhouse), you cannot duplicate NFTs - it’s already recorded on the blockchain, so it’ll be the only unique one on the chain. Even if somebody were to create another token with your info, you can still say that the duplicated token is not your token because you can prove when the duplicated one was created after your token was, and can even prove each transaction done with your specific token. Plus, to even hack the blockchain, iirc it would require one party to have over 50% of the processes running it - which is reportedly hard to do, so take that for what you will.

IMHO technically speaking the concpt of a Blockchain and decentralized zero trust computing like in Ethereum are indeed "interesting" as concepts.

VeeSilverball@kbin.social ⁨1⁩ ⁨year⁩ ago
My principle of "blockchain's fundamental value" is simply this: A blockchain that secures valuable information is valuable.

To break that down further:

"Valuable information" isn't data - it's something that you can interpret, that has meaning and power to affect your actions. So, price speculation taking place on a chain isn't that valuable in a broad, utilitarian sense, but something like encyclopedic knowledge, historical records, and the like might be. The sense of "this is real" vs "this is Monopoly money" is related to the information quality.

"Secures" means that we have some idea of where the information came from, who can access it, and whether it's been altered or tampered. Most blockchains follow the Bitcoin model and are fully public ledgers, storing everything - and just within that model(leaving aside Monero etc.) there are positive applications, but "automatically secure" is all dependent on what application you're aiming for.

You don't need to include tokens, trading, finance, or the specific method of security, to arrive at this idea of what a blockchain does, but having them involved addresses - though maybe without concretely solving - the question of paying upkeep costs, a problem that has always dogged open, distributed projects in the past. If the whole chain becomes more valuable because one person contributes something to it, then you have a positive feedback loop in which a culture of remixing and tipping is good. It tends to get undercut by "what if I made scam tokens and bribed an exchange to list them", the maxi- "we will rule the world" cultures of Bitcoin and Ethereum, or the cynical "VC-backed corporate blockchains", but the public alt chains that are a bit out of the spotlight with longer histories, stuff like Tezos and NEM/Symbol, tend to have a more visible sense of purpose in this direction - they need to make a myth about themselves, and the myth turns into information by chance and persistence.

What tends to break people's brains - both the maxis, and people who are rabidly anti-crypto - is that securing on-chain value in this way also isn't a case of "public" vs "private" goods. It's more akin to "commons" vs "enclosed" spaces, which is an older notion that hasn't been felt in our political lives in centuries, because the partnership of nation-states and capital has been so strong as a societal coordinating force - the state says where the capital should go, the people that follow that lead and build out an empire get rewarded. The commons is, in essence, the voice in the back of your mind asking, "Why are you in the rat race? Do you really need an empire?" And this technology is stating that, clearly and patiently: making a common space better is another way to live.

And so there is a huge amount of spam around "ownership", but ownership itself isn't really a factor. That's just another kind of information that the technology is geared towards storing. The social contract is more along the lines that if you are doing good for a chain and taking few risks, a modest, livable amount of credit is likely to flow to you in time. Everyone making "plays" and getting burned is trying to gamble with it, or to advance empire-building goals in a basically hostile environment that will patch you out of the flow of information.

Asset Tokenization and Smart Contracts are two things that will be increasingly used in Finance. That is why the recent BIS report on CBDCs included both of those as essential features of a Central Bank Digital Currency.

What Blockchain does is provide these features of a digital currency in a way that doesn’t require a trusted intermediary. This makes Blockchains resistant to censorship in a way that a central bank digital currency can never truly guarantee. It is true that a centralization system like a database or ledger can be faster, more efficient and more secure but that you will always have to trust that provider of that service that they will continue operating in a manner that is congruent with what a user may want.

A recent example of this would be the news that Ubisoft is deleting inactive accounts on Uplay, which is potentially resulting in many users losing access to games they bought on that platform. Where the rights to those game tokenized on a Blockchain or CBDC, the users could potentially redeem that on another platform. Another example would be the case of the user losing his 900 hour character in Red Dead Redemption after Google shutdown stadia. Had that player’s character been tokenized as an NFT he might have the capacity to move it off of stadia and onto another game platform.

Get a little nervous about your Steam Game collection worth 1000s of dollars that is completely locked into Valve’s ecosystem? How about a decentralized, immutable and censorship-resistant record of your ownership of those games? That is what asset tokenization is about and it will become more important in the future as our lives and our assets become more digital.

Then there are multitude of uses for smart contracts which, again, don’t require a blockchain provided you are ok with relying on a trusted intermediary to execute the contract as it was termed. Given that contracts by their nature often involve agreement between organization or individual with diverging interests, it almost a certainty that having an immutable, censorship resistant network to run those smart contracts is desirable.

As we see here on the Fediverse, decentralization works fine without monetization using an actively anti-scaling append only database that emits the pollution of a medium sized country.

    The problem is how do you use that system with a sceptical public that doesn’t understand or trust it. A technical enough person night understands it, but to the vast majority of people it may as well be “trust me, bro”. It’s a lot easier to trust a physicial piece of paper.
    
    Not to mention that an important part of voting is anonymity, which a Blockchain doesn’t really give you. How do you validate that a vote on the chain is legitimate without some kind of trail back to an actual human?

  That’d probably be a component. The problem with digital elections is that they’re EXTREMELY complicated. Complexity means risk of error and you don’t want to fuck up an election. We’ve already seen the fuss people make when I

I’ve heard of a couple interesting applications (interesting doesn’t necessarily mean good)

I’ve been out of the industry for a couple years, but at the time I left both the US’s NAR and CA’s CREA were looking to create blockchains that would eventually hold an immutable history of every salable property in North America. The sales pitch is that no one will ever be able to hide things like flood damage or zoning changes if they’re all those events are in a trusted database.

Several US states with legalized Marijuana have what are known as Seed To Sale laws. One company was trying to move into this space and eventually into all of agriculture. The idea being that if you buy pot scanning a QR code would tell you what clone# the seeds were from, where and when it was planted, what pesticides/herbicides were used on/near it, when it was harvested, any tests it had gone through, etc.

Could be used for coordinating large scale decentralized projects. Say we want to organize logistics of food so that everyone gets some. After calculating need for each locale independently, Blockchain could be used for people to commit to, for example, bringing 4 crates of carrots to a location for shipping. Additional blockchain ledgers might keep track of space on the transportation vehicles etc. The ledger’s main job here would be to ensure that a given task (or a given cubic foot for the space example) is not double booked.

  What value does Blockchain provide here? It feels like none whatsoever.

If you take a longer historical view, there have long been strong opinions about how we should base our currency. Because money impacts us all so viscerally, even the most uninformed develop deep seated emotional stances about very obscure topics.

en.wikipedia.org/wiki/Cross_of_Gold_speech

This link is an example of a historical moment where a stance taken against the gold standard was influential in national elections in the US.

The people who would have been emotionally exercised about bimetalism are probably the same people who we call crypto-bros today.

In all, the furor over blockchain, especially currency and NFT, has yielded heat but no light. Where’s the killer application? It never takes this long for a truly useful technology to find that killer app, not in today’s technology environment. Maybe it just isn’t that useful and people should calm down?

I've been thinking about this for a while, and would love to have other, more knowledgeable (hopefully!) opinions on this:

I've been dwelling on how we might be able to enforce some sort of set of rules or widely agreed upon "morals" on artificial general intelligence systems, which is something that should almost certainly be distributed in order a single entity from seizing control of it (governments, private individuals, corporations, or any AGI systems), and which would also allow a potentially growing set of rules or directives that couldn't be edited or controlled by a singular actor--at least in theory.

What other consideration would need to be made? Is this a plausibly good use of this technology?

  Blockchain is at its core just an Excel spreadsheet. The only thing it adds is some form of distributed consensus (which may or may not work depending on who you ask).
  
  If you can figure out how to use an Excel spreadsheet to enforce morals in an AI system, then you’re good to go.

I have wet dreams about a new text based mesh internet powered by the gemini protocol. Imagine, if you will, instead of paying monthly to your ISP/cell service provider to acess the internet, that instead you bought an ‘internet box’ once. Where each router/gateway acts both as a self-hosting site for the user, and transmits this site text data to other local routers through LoRaWAN. There are many technical challenges to this kind of networks, one being “how do I check that all other routers have an up-to-date version of any one site?” and blockchain technology seems to fit nicely for that particular issue.

I believe there is an initiative by some big banks to push for wire transfers to be done via a blockchain as opposed to slow ach transfers.

They call it quantum computing or something like that… but seemed like it had potential to solve some issues with slow banking
