  • It’s an objective improvement over EMV which doesn’t protect privacy at all.

    Taler protect payer privacy while exposing income information. Meaning it can help collect taxes to pay for infrastructure, education, public service, …

    That’s a fine compromise. I hope Taler become a practical alternative to EMV and other shitty payment systems being pushed by banks.



  • same on all chains. All have a proposal, discussion, implementation, waiting period (for code to be deployed), and activation

    I though most of those steps didn’t occur on-chain in the case of bitcoin. But I could be mistaken.

    Would you mind sharing a link with the equivalent information on bitcoin, ie its governance process and how each governance operation (proposal, vote, activation ) is handled by the chain?

    I’m looking at BIP-1. It explains how to submit a proposal via mailing list and versioned repository, ie off-chain.

    Also looking at BIP-9. It does rely on the chain for governance, and allow polling for the most popular soft-fork. But it focus on exclusively on testing soft forks, which severely limit its usefulness.

    allowing multiple backward-compatible changes (further called “soft forks”) to be deployed in parallel.

    It seems BIP-9 doesn’t provide a solution to propose/vote/activate the larger non-backward-compatible changes, ie doesn’t help prevent hard forks. And big social and environmental issues affecting bitcoin probably require such large change.


  • Tezos would still require all nodes to upgrade to the code which contains the new algorithm. It can’t just automatically know what the new code is. It then can schedule these to activate at a certain block using a signaling system of some sort.

    Code proposal, vote on new code activation of new code, are all Tezos on-chain operation. These operations include a hash of the new code to be deployed. There’s some off-chain work happening to update tools, which I guess include compiling said code. So you’re right, some off-cain action is needed for deployment https://www.tezosagora.org/learn#an-introduction-to-tezos-governance

    My understanding is that compared to BTC governance, a larger part of the process happen on-chain. Also there is a relatively smaller portion of nodes (baker) involved in creating/verifying blocks that must update. This allowed various protocol changes without forks over the years.



  • lol it can’t adjust on public approval. It’s software that runs.

    It can. Software is written by people. Its authors can build it with an update mechanism.

    Crypto currencies such as Tezos have a vote-based update mechanism and a community that periodically submits algorithm changes for approval.

    Bitcoin doesn’t have a update mechanism that allows smooth changes. Its take it or leave it (aka hard fork). Peole can move away from it, and it’s sad that so many still haven’t.


  • The network was built to adjust

    Then why doesn’t it adjust to avoid negative social and environmental effects? Probalby because it’s not possible to adjust bitcoin’s algorithm, only some parameters, and because miners don’t have enough intensive to abandon bitcoin for something less destructive.

    My understanding is it’s not possible to modify nor fix bitcoin’s core algorithm, which include the difficulty and consensus logic.

    A hard fork is possible, which means leaving the bitcoin network and setting up an alternative (hopefully better) network with a different algorithm.


  • Likely bad coding or bad database design.

    Best practice is to avoid using email as primary key in the user database, instead use an internal ID, so that an email change can happen without touching the primary key.

    Your reply made me think of an alternative to deleting accounts : replace personal information to use a pseudonym and a throwaway email, remove everything that can be removed.

    That would help once the badly coded website get hacked or its database get leaked.





  • Thanks for the refresher. I’m aware of the basics, but assumed the difficulty measured by the number of zeros could only increase. Apparently difficulty can decrease, and I’ve read it’s expected to decrease very soon to keep the system running a while longer.

    Bitcoin’s creator was smart enough to design a system that automatically adjust to remain profitable for several years without intervention, but not smart enough to foresee social and environmental costs.

    It’s a good example that illustrate why automated systems shouldn’t be left running unsupervised, even if it’s designed by the best minds with the best of intentions.


  • The headline isn’t accurate as usual, but isn’t completely wrong either. Anyway, the article you’ve quoted is more informative than the one I posted, so thanks for that quote.

    We’re at a point where it’s no longer profitable for individual miners, even if we ignore externalities like the cost we’re collectively paying due to pollution and carbon emissions.

    Mining require increasing amount of energy and resources as time pass, so unless there’s a radical change in bitcoin’s algorithm or unless energy becomes free, we should expect mining to get non-profitable in more and more situations.








  • Somewhat obvious tips to get a more stable experience:

    • Use a distribution that favour stability over being on the bleeding edge. Like Debian stable, or another distribution that maintain LTS releases,
    • Install software from the distribution’s official package repositories. Avoid third party packages and repos as much as possible. If you really need a third party repo, verify it’s compatible with your specific distro and has reputation for being well maintained,
    • When you do see a problem, take time to troubleshoot and if necessary make a bug report with necessary information for developers to identify the problem, so there’s a better chance to see it fixed.
    • If you use Linux in a professional settings, there is paid support available out there, in some cases this get you priority for bug fixes.
