It does? I am hoping I'll be able to use it as a public, distributed ledger, and so, too, are many major financial institutions — if they can be said to "hope"

It does? I am hoping I'll be able to use it as a public, distributed ledger, and so, too, are many major financial institutions — if they can be said to "hope". Are you suggesting that this aspiration is naive?

Ethereum worked very well with the DAO...for the hacker that stole several million and that forced them to fork. I will never trust a system where they can decide arbitrarily to void all the transactions that everyone made after several days.

    You can get insurance with the current banking system.

      As long as you have the money to prove the law is on your side.

        That's not relevant. A bank account is an insurable device. An ethereum implementation is not. Until that changes, nobody will take it seriously.

    I never heard that all the transactions in the world got rollbacked after days, and I don't think it is even technically possible. Doing that in ethereum and all the other similar currencies is as easy as pressing a button.

  The way I recall it, they didn’t void past transactions; they added “irregular state changes” that would “return” the “stolen” funds to their “legitimate“ owners. Nor were they forced to fork; it was a voluntary decision of a group of people with enough social power over the platform. Now this is more a matter of dispute, but I wouldn’t say the hacker stole the funds. They simply followed the DAO contract (not the “smart-contract”, mind you, but the one put forward by the Slock.it team on their page), according to which everything that went on the blockchain according to the DAO code was legitimate.

    >Now this is more a matter of dispute, but I wouldn’t say the hacker stole the funds... Verification is Ethereum's Achille's heel. Everyone seems to trust that someone else will verify that the contracts they participate in will work securely as intended, and the DAO showed how well that works. If Ethereum ever gets used as its proponents imagine, with multiple interacting contracts in progress at any given time, rolling back an error will not be nearly as easy as it was in the DAO case (and that was not particularly easy.)

      That's every system's Achille's Heel. It's a human fault.
      - mannykannot 10y ago
        The point is that in Ethereum's case, the extent of the problem is vastly underestimated by almost all of the participants. In most other cases, it is a risk that can be mitigated or accepted, but in Ethereum's case, it undermines the fundamental premise ('trustless' contracts.)

  Nobody forced anything. A bunch of people agreed to use new rules with old data, which is why the new chain is in common use. Democracy in action. The same could happen to literally any cryptocurrency you could think up, unless you can come up with a way of invalidating past state to a point where nobody can use it with a new set of rules - which is impossible unless you can somehow cryptographically encode the rules into the chain to a point where you can't access the data without adhering to the rules. (I think a zkSNARK could help with this if it's something that people actually desire.)

      People could've kept using a continuation of the old chain without breaking anything. In fact, some did - see Ethereum Classic. People decided to use the forked Ethereum because they believed it was the correct choice, not because someone made them.
      - duozerk 10y ago
        Oh, absolutely. I'm still an interested watcher/user of ETC. And indeed, people "voted" in the end with their mining power (which is why the original chain hasn't disappeared). I just believe that their actions basically destroyed any future that ETH (and likely ETC too) might've had - it's dead; if the initial hard fork wasn't enough to remove all credibility in the project, the circus since then (subsequent forks, attacks, incredibly mismanaged communication...) certainly is.
