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.
Good point, with BIPs the Bitcoin community is more adaptive than I gave it credit for.
It still doesn’t prevent soft nor hard fork. My understanding is that a change in Bitcoin’s consensus logic require ALL users/miners to take action to deploy the new software to avoid hard forks. That’s impossible in practice. So a BIP to change the consensus logic, either tweaking or replacing PoW, would necessary cause a hard fork even if it’s approved.
Not all chains handle this the same way nor suffer from this. For instance, using Tezos means automatically accepting algorithm changes after they are approved. This makes hard forks much less likely.
Bitcoin sure have more hype and higher price, but appears to have more difficulty evolving compared to others.
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 an 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.
Those companies doing business in the EU should have been looking for alternatives since at least 2016 when GPDR was adopted.
It doesn’t seem realistic to rely on targeted advertising if that require opt-in, informed consent. I suspect only a small fraction of visitors would agree.
I hope contextual advertising and similar less-invasive approaches becomes the norm again. Contextual advertising have been used for decades in Newspapers, on the TV and radio.
Please have Police focus on better using the data it already has. Rather than just giving it the power to hoard more personal data and endangering public liberties.
Existing police records are riddled with errors:
Piling more data on top won’t fix these errors. Putting more effort in fixing errors would make the records more useful to police, and would probably avoid ruining the lives of innocents people.
Like how Stephen Colbert setup his own SuperPac on air, showing how many ridiculous and unethical things are legal with US’ current campaign finance laws.
This alone doen’t make you a Nazi, but that’s still a terrible course of action.
A wise man once said…
Calling out Musk and his actions, and avoiding the company that he owns and control, are the least one can do given all the trouble he’s causing, or trying to cause.
Several companies sell electric vehicles, and unlike Tesla, most aren’t owned by a Nazi (sympathiser).
911 and similar emergency numbers always cost money.
In many places individuals pays for it through taxes, but people may not realize it because there’s 1 tax and 1 big budget that pays for many different public services.
In the US I guess the cost is separated from other public services, and paid through ISP via a fee.
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.
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.
