Blockchain is a solution in search of a problem. A way to establish trust while not trusting any party is a cool concept, but in the real world it’s far easier to establish a source of trust.
Congratulations, now your trust relies on your subject never becoming important enough that someone bothers to run 50%+1 of the nodes in your network which means only very, very large subjects (or ones where trust wasn’t very important in the first place) ever even have a chance of that not happening. What do you say? Your technology doesn’t scale to very, very large subjects because of abysmal transaction rates?

Yup. Very well said. People don’t realize the extent of wealth inequality (and how ridiculously resource intensive blockchain tech is). If anything important were to be decide by a blockchain, the top 1% would control the network.
I have a friend who works at a major bank and they use Blockchain technology to keep track of something or other internally, though I don’t remember exactly what. In this case at keast we can bet that it has found a problem wirth using it to sokve. Banks are nothing if not efficient.
I find it funny that it was touted as an alternative to the current banking system and ended up being absorved into it though
Banks are businesses made up of people. If a manager thought he could get a promotion by supporting a blockchain project at the height of blockchain mania, that’s what he would do. Whether if fails or not is of no consequence, the manager is already on another project.
If it’s used internally, then I question whether it made sense to use blockchain. At the end of the day, it’s probably the trust in the bank that matters and not blockchain.
Nah. the commenter above is just wrong. It’s just that anyone who isn’t selling bullshit uses their real name- Merkel trees
- which are fundamental to modern software development (git, zfs, nix, nosql).
That’s a similar but different concept. Blockchain adds a way to determine consensus of the correct tree. While git is distributed, it’s generally not trustless, there’s generally a trusted version of the repository.
what? Git is very much distributed and while you can have a main branch, you can set as many up streams as you want and merge things sideways.
It’s trust less in the sense that commits can’t be easily forged and are signed with cryptographic keys and identities-- as in, I don’t have to trust that the source code is genuine since I can verify the commit history myself.
Consensus is just a pull request.
That wiki article literally lists Bitcoin and Ethereum as implementations of Merkel trees.
How is it any different than verifying that a transaction occurred?
With a centralized trust source (bank), you ask for the records.
How is a trusted repository different from a hard fork?
Because you check who owns and maintains it. A notable example was with Simple Apps for Android, earlier this year the main repo was sold to a company. Trust was lost, thus a fork was created to keep the original stuff.
We define “blockchain” and “blockchain network”, and then discuss two very different, well known classes of blockchain networks: cryptocurrencies and Git repositories.
Is it easier to establish a source of trust?
With blockchain trust lies in the protocol and in the node operators who make decisions about how to operate their nodes. Running a node isn’t extremely difficult. Running a financial institution is difficult.
Well, sure, now you have a currency that doesn’t rely on trust
…now what? How are you going to spend that currency if you don’t trust anyone? How will you ensure you get what you bought? How will your property get protected? Hell, how do you get others to agree that your crypto is the one they should use?
It’s trust all the way down. Removing it from one small part of the chain isn’t going to fundamentally change things

More on wealth inequality here.
Today’s inequality was created by the Cantillon effect.
What happened in 1972?

I envy your trust in the efficiency of banks
Banks are businesses made up of people. If a manager thought he could get a promotion by supporting a blockchain project at the height of blockchain mania, that’s what he would do. Whether if fails or not is of no consequence, the manager is already on another project.

Interesting. Good to know. Thanks!
Blockchain is effectively a distributed database. Almost always a good centralized database functions better.

I’m pretty sure being able to verify that the person responsible for a push is an actual maintainer is the opposite of trustless.

Isn’t “proving someone is a maintainer” just an IRL proof of stake?

Right, but isn’t the “main chain” of Ethereum based on a similar principle wherein it’s the main chain because it’s the one the devs use?
What about BTC vs BTC lightning.
I’m genuinely failing to see a distinction here, and, again, the wiki article says that blockchains are special cases of Merkle trees.
