There's a big debate about it in Technical Discussion as achow101 mentioned.
Some short videos from Matthew Kratter to get you up to speed on the matter more quickly:
From discussions I have read elsewhere, none of the videos he has posted are actually accurate and supposedly he is significantly overexaggerating/being hyperbolic. I cannot attest this as I have not watched them myself.

the announcement was made a couple days ago by the devs and the PR will be merged. We will see.
There is no such announcement that anything will happen. I would happen to know, as I am one of the maintainers.

The document that was published a few days ago was a draft of one that had intended to be "official" from the project, but it did not have enough agreement amongst contributors to adopt it as such. The author then published the draft. It is neither an announcement nor the project's "official" stance on the topic.



Regardless, continued discussion of OP_RETURN limits is off topic for this thread and I will be removing any further posts on the subject. Go to the myriad of other threads/forums where this is being discussed.

Thank you for the info. It is a relief to hear that. I am hearing a lot of conflicting information right now.
Some articles came out yesterday claiming otherwise so I don't know what to believe.

Bitcoin Developers Plan OP_RETURN Limit Removal in Next Release
https://finance.yahoo.com/news/bitcoin-developers-plan-op-return-062522161.html

Bitcoin Core to unilaterally remove controversial OP-Return limit
https://cointelegraph.com/news/bitcoin-core-unilaterally-remove-controversial-op-return-limit

It appears they are using dev comments on Github as their source but that is not an official announcement.
I guess the only way to know for sure is when the next release of Core comes out.

You can follow the discussion on the pull request but also in the email lists. That is much better than reading articles by under qualified writers that are posing as Bitcoin journalists.

How come the latest version still won't support seed phrases?

Well, my Bitcoin core was corrupted for some reason, and I had to uninstall it. I don't remember if there is an option to recover or create a new wallet with seed phrases. I assume most people on the internet do not use Bitcoin Core as a wallet. They just run the Bitcoin core to help the network. For wallet purposes, it is recommended to use Electrum.

There might be other software wallets with better services, but I find Electrum easy to use and safe, and I have been using it for a couple of years now.

According to ChatGPT

Quote from: ChatGPT
Bitcoin Core does support seed phrases, but not in the same way as other wallets like Electrum or hardware wallets do. Bitcoin Core typically uses a 12-word seed phrase for generating and backing up wallet keys, starting from version 0.21.0 (released in 2020).

Here’s how it works:

Bitcoin Core 0.21.0 and later includes an option to create a new wallet with a seed phrase, similar to how many other wallets operate.

The seed phrase is used to restore the wallet and its private keys, which is crucial if you ever need to recover your wallet.

In these versions, when creating a new wallet, you can either create a wallet normally (with no seed phrase) or you can select the option to generate a wallet with a seed phrase for better recovery options.

Bitcoin Core uses a BIP39 standard for seed phrases (12 or 24 words). However, you should keep in mind that Bitcoin Core isn’t primarily designed to be a user-friendly wallet like others, such as Electrum or mobile wallets, so some advanced users prefer to use it as a full node to interact with the Bitcoin network directly.

Anything about addressing the migration for countering quantum computer? Are we waiting 2030?

No. For that you need to follow the BIP repository and the developer mailing list. Quantum resistance research is still in progress and it is unlikely that an implementation will be available or merged very soon.

Excuse my ignorance, what is the BIP about quantum research? And how can I stay up to date on this topic?

Excuse my ignorance, what is the BIP about quantum research? And how can I stay up to date on this topic?
There is only a draft BIP with the tentative number 360. I had opened a thread about that discussion.

It's however unlikely the BIP will be implemented soon. The problem is that the developers don't consider the current post quantum algorithms to be mature enough, and for example @achow101 (a Bitcoin developer) has stated in that thread that he'd prefer to choose a single, battle-tested algorithm, instead of letting the users decide which algorithm to use (that can be dangerous because many users have no idea about the safety of the different algorithms and their particular challenges and potential vulnerabilities).

I personally think that it is reasonable to wait a couple of years more, because quantum computers with hundreds of thousands of logical qubits would be needed to crack a Bitcoin key in several years, and millions if it should happen in a few days. That's imo at least a decade, if not a century away. (And afaik you can't just connect several 1000-qubit-machines to create a million-qubit supercomputer.) And until quantum computers can crack keys in a few minutes, there is a simple strategy to make coins "almost" quantum safe: don't re-use your addresses, and thus no public key is exposed.

The best way to stay up to date about development issues is to follow the Bitcoin-dev mailing list. There was a quite long discussion about the proposed BIP360.

The NIST have already released quantum-resistant replacements for the SHA-256 and EDCSA encryption used by bitcoin.
They are called FIPS 203, 204, 205. NIST is the US federal agency that originally created SHA and EDCSA encryption methods.

NIST Releases First 3 Finalized Post-Quantum Encryption Standards

• NIST has released a final set of encryption tools designed to withstand the attack of a quantum computer.
• These post-quantum encryption standards secure a wide range of electronic information, from confidential
email messages to e-commerce transactions that propel the modern economy.
• NIST is encouraging computer system administrators to begin transitioning to the new standards as soon as possible.


The question is, if and when the devs will start implementing them into bitcoin?

The general view is that this field is still in its emergence and that more changes will come. Bitcoin is not the kind of technology that allows for making fatal errors with minimal consequences. The consequences of adopting the wrong algorithm could be devastating. Keep in mind that knowledge in this field is still lacking, i.e., there are too many unknowns. What seems secure today could become insecure tomorrow as quantum computers actually start getting used and we discover new ways of attacking encryption and hashes. Anyhow, some of these algorithms may be rejected for different reasons here but they may be useful somewhere else. Decentralized systems have different limitations and restrictions than centralized systems.  

Furthermore, Bitcoin is generally a very slow mover. I'd expect at least a few more years to pass before we start considering some "final candidates" for our replacements. Note that I am talking about final candidates for Bitcoin, not final candidates as given by NIST. Unless something forces us to act faster.

That makes sense. One of the questions concerning the process of future-proofing bitcoin
to me would be how to protect legacy addresses from a quantum attack, addresses where
the private keys may have been permanently lost.

Potential solutions:

1. Provide plenty of warning and time for people to move their bitcoin before permanently
"locking" legacy addresses. Of course, doing that would be highly controversial.

2. Do the above, but provide a means for the owner of a locked legacy address to prove
ownership by "signing" the bitcoin and restoring their access. I have no idea if that would even be possible.

3. Something else

If you want to seriously discuss this, it would be better to open a new topic in Development & Technical Discussion as it would be off topic to continue this here. I've seen pieces of this discussion in many threads though.
