People will not agree to shrink the maximum block size. However, if you want to kill inscriptions, there is another approach, that could be used to force them into second layers: it is called cut-through, and was described in this topic: https://bitcointalk.org/index.php?topic=281848.0
Then, if you have "Alice -> Bob -> ... -> Zack" transaction chain, and for example some inscriptions were created in "Alice -> Bob" transaction, then cut-through could remove those inscriptions, while leaving the payment unaffected, because the proper amount of coins will be received by Zack, as it should be.

It is important to also note that proof of secret key schemes are highly data inefficient and likely would have a higher cost for users than simply allowing arbitrary data to continue. In ECDSA, purposely re-using k values allows you to encode data in both k and the entire secret key, as both become computable. Or, one could bruteforce a k value to encode data in a sig, as is done in some compromised hardware key exfiltration attacks. Additionally, one can bruteforce keys in order to encode data in the public key.
It is very difficult and expensive to attempt to limit the storage of arbitrary data in a system where the security comes from secret keys being arbitrary data.

You are incorrect: cut-through transactions will not meaningfully affect
inscriptions. While it is true that with fancy cryptography we can prove the
Alice -> ... -> Zack chain, that does not change the fact that Alice -> Bob ->
Zack was mined in the blockchain, and those transactions exist. Anyone running
a full archival node will still have those transactions, and can provide them
(and all their inscription data) to anyone who needs it.
This is not unlike how in Bitcoin right now many people run pruned nodes that
do not have any archival inscription data. Them running those nodes does not
prevent others from running full archival nodes that do make that data
available.

If you use it in that way, then cut-through is pointless. The whole point of using it is scaling. If you have only "Alice -> Zack" transaction, that is included in some block, then cut-through is really useful. In other cases, if you include all transactions anyway, and create only a proof for some nodes, then it doesn't scale, because you have to always process those transactions in the middle, while there is no need to do so. It is needed only during batching, to prevent double-spending, but if it is deeply confirmed, then who needs something that doesn't scale?
Also, going in that direction is a natural consequence of enabling full-RBF: transactions will be replaced, which means mempool-level-batching (ideally non-interactive, done automatically by nodes) will be next, sooner or later.

indeed, i once added a proof-of work requirement to public keys on an open
relay server protocol, in additon to posk, in order to make it harder to
roll new keys and access the network as a spammer/scammer. not hard to
embed anything in a public key, but you can't embed too much, especially if
you want mobile devices to be able to generate a new key in under a few
minutes.

As I understand it, protecting against this is exactly the reason why a
blocksize limit exists. Perhaps it should never have been increased in the
first place.
Given the current concerns with blockchain size increases due to
inscriptions, and now that the lightning network is starting to gain more
traction, perhaps people are now more willing to consider a smaller
blocksize in favor of pushing more activity to lightning?

Good Morning List,
understanding the strategy wrongly or purposelydriving the interaction into a false framing doesn’t benefit Bitcoin. Mentioning <ban"arbitrary data"> or <governments try tocensor> distracts from the proposed strategy.
The strategy aims to increment the coercion cost of mining-entities relative to the cooperation cost of mining-entities in regards of arbitrary data insertion; it is not about banning or censoring.
Mentioning other ways or methods to insert arbitrary data should not be understood as a threat or menace, but much more as topics which each Bitcoin developer should have in mind to solve.
It is healthy to assume that arbitrary data insertions are nothing but innocent or negligible. The Bitcoin system is still in the struggle of two visions:
- One controlled by every node operator and highly decentralized. (Nobody alone controls)
or
- One controlled by a few very highly capitalized entity node operators and highly centralized. (A committee controls).
The best tactical way to reach the latter is via prohibitive cost increment for operating a regular Bitcoin node (aka. archival full node). That will reduce the network decentralization making it susceptible for central entity elimination or control acquisition; and not necessary by a national-state government.
Chris

If we attempt to ban "arbitrary data", those users will simply respond by "tunneling" their data over innocent-looking public key data instead.

Note that in the Mimblewimble protocol, range proofs already prove
knowledge of blinding factor in Pedersen commitments, and thus no
additional padding is needed there to prevent the encoding of spam
into cryptographic material. This makes pure MW blockchains the most
inscription/spam resistant [1].

Good morning Russel and List,
That is correct. There is a counterparty-compatible project called STAMPS that breaks up image data into chunks and then embeds the chunks in bare multisig outputs. here is an example on one: https://mempool.space/tx/ee9ed76fa2318deb63a24082a8edc73e4ea39a5252bfb1c1e1c02bd02c52f95f
This consumes more space and bloats the UTXO set compared to stuffing data in a witness.
There are schemes like Pay-to-Contact ([https://bitcoinops.org/en/topics/pay-to-contract-outputs/](https://bitcoinops.org/en/topics/pay-to-contract-outputs/#:~:text=Pay%2Dto%2Dcontract%20protocols%20allow,that%20commits%20to%20that%20text)) that could be used to tweak a pubkey with a small blob of data, in which case someone could produce a signature proving knowledge of the private key.

It's been said before, but I'll say it again:
If we ban "arbitrary data", however you want to define it, then actors will
simply respond by encoding their data within sets of public keys. Public
key data is indistinguishable from random data, and, unless we are willing
to pad the blockchain with proof of knowledge of secret keys, there will be
no way to tell a priori whether a given public key is really a public key
or whether it is encoding an inscription or some other data.
When certain governments try to censor certain internet protocols, users
respond by tunnelling their protocol through something that appears to be
innocent HTTPS (see Tor bridge nodes). This works because, after a
handshake, the remaining HTTPS stream, like public keys, is
indistinguishable from random data, and can be used as a communications
channel for arbitrary data. If we attempt to ban "arbitrary data", those
users will simply respond by "tunneling" their data over innocent-looking
public key data instead.
Please correct me if I'm wrong, but I believe Counterparty has, in the
past, encoded their data within public key data, so this concern is not
hypothetical.

It is already more than a half year since the probably mayor Bitcoin script exploit started.
These exploits are nothing new in the Bitcoin history and mostly are due to the loose flexibility of the system in regards of processing predicatives (Bitcoin script). The very first mayor bug; if you wish, vulnerability, was the CVE-2010-5141, which still engages us without end even after 14 years.
Subsequent Bitcoin historical events let to build more “improvements” upon this wobbly basis exposing even more ground for exploits.
As long as this loose flexibility is not modified in a way its exposure for exploits is eliminated remains nothing else than to pursue other strategies; and ones which are compatible with the current status quo and furthermore, with a permission-less system.
Here a strategy proposal:
Let’s name it: #Ordisrespector and #Ordislow.
Why #Ordisrespector and #Ordislow are compatible with a permission-less system.
#Ordisrespector gives the option to a regular Bitcoin node operator to opt-in or not to a self-defense of his/her storage property (and thus of his/her integrity); by giving a signal of dissatisfaction with the current affairs of aggression via insertion of arbitrary data into the witness structure. This dissatisfaction signal is manifested by not taking into the mempool and relaying transactions with inserted arbitrary data in the witness structure.
#Ordislow gives the option to a regular Bitcoin node operator to opt-in or not to a self-defense of his/her storage property (and thus of his/her integrity); by increasing the coercion cost of mining-entities relative to the cooperation cost of mining-entities due to the current affairs of aggression via insertion of arbitrary data into the witness structure.

Utreexo only seems to save us time if it is used in "bridge" mode otherwise it takes soft fork for all nodes to use Utreexo at the price of larger transaction.
The problem is not here for the moment, it is imperative to solve the problem of inscription that quickly brings us closer to the need for Utreexo.

After looking into this more deeply (thanks to Luke Dashjr for pointing me
in the right direction) it is now clear to me that storage isn't the real
issue, but rather the "initial blockchain sync" time - in which storage
certainly has a significant role to play, at least currently.
At the moment, UTreeXO seems like a promising first step. Perhaps there is
a more efficient way to sync the chain without having to download
everything and while still verifying it trustlessly.

Storage is not and never has been the trouble with block sizes. Please,

True, the real question is whether the storage is in fact sufficiently
limited. And I believe the answer to be 'yes'.
Why? Consider a worst case scenario using the maximum block size of 4MB and
a block time of 10min, that's a growth of 210.24GB per year. Some of that
can be pruned, but let's just assume that you don't want to. And currently
the entire blockchain is roughly 500GB.
Now that looks like a lot of growth potential based on where we are at now.
However, with the current cost of hardware, you can get a 5 TB hard drive
for less than $150. That will last you 21 years before you run out of
space. That's less than $0.02 per day.
That is a worst case scenario.
Consider that since cost of hardware drops over time, it will become less
of a burden over time.
Also, keep in mind there are efforts to optimize how much of that actually
needs to be stored by nodes. For example, the aforementioned topic
announcing Floresta which seems to be a node implementation that uses
utreexo to allow nodes to run without needing to maintain the full UTXO
set. Other initiatives exist as well.
There is definitely a lot of optimization potential for drastically
reducing how much space is actually needed by individual nodes.

Hello,
> This cat and mouse game can be won by bitcoin defenders. Why ? Because it is easier to detect these transactions and make them a standardization rule than to create new types of spam transactions.
One of the things discussed during the mempoolfullrbf discussion is that a small (~10%) of nodes willing to relay a class of transaction is enough for that class of transaction to consistently reach miners. That means you would need to get nearly the entire network to run updated relay policy to prevent inscriptions from trivially reaching miners and being included in blocks. Inscription users have shown that they are willing and able to send non-standard transactions to miners out of band (https://mempool.space/tx/0301e0480b374b32851a9462db29dc19fe830a7f7d7a88b81612b9d42099c0ae), so even if you managed to get enough of the network running the new rule to prevent propagation to miners, those users can just go out of band. Or, they can simply change the script that is used to embed an inscription in the transaction witness. For example, instead of 0 OP_IF…, maybe they do 0 OP_DUP OP_DROP OP_IF. When the anti-inscription people detect this, they have to update the rule and wait for 90%+ of the network to upgrade. When the pro-inscription people see this, they only have to convince other inscription enthusiasts and businesses to update.
The anti-inscription patch has to be run by many more participants (most of whom don’t care), while the pro-inscription update has to be run by a small number of people who care a lot. It’s a losing battle for the anti-inscription people.
If you want to prevent inscriptions, the best answer we know of today is economic: the cost of the blockspace needs to be more expensive than inscribers are willing to pay, either because its too expensive or because there’s no market demand for inscriptions. The former relies on Bitcoin becoming more useful to more people, the latter is the natural course of collectibles.

According to you, the rules of standardization are useless but in this case why were they introduced? The opreturn limit can be circumvented by miners, yet it is rare to see any, the same for maxancestorcount, minrelayfee or even the dust limit.
This cat and mouse game can be won by bitcoin defenders. Why ? Because it is easier to detect these transactions and make them a standardization rule than to create new types of spam transactions.
As for the default policy, it can be a weakness but also a strength because if the patch is integrated into Bitcoin Core by being activated by default, the patch will become more and more effective as the nodes update.
Also, when it came to using a pre-segwit node, it is not a solution because this type of node cannot initiate new ones, which is obviously a big problem.

Note that some people, even on this mailing list, do not consider Ordinals as spam: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2023-February/021464.html
See? It was discussed when it started. Some people believe that blocking Ordinals is censorship, and could lead to blocking regular transactions in the future, just based on other criteria. That means, even if developers would create some official version with that option, then some people would not follow them, or even block Ordinals-filtering nodes, exactly as described in the linked thread: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2023-February/021487.html
> as spammers might perceive that the Bitcoin network tolerates this kind of behavior
But it is true, you have the whole pages, where you can find images, files, or other data, that was pushed on-chain long before Ordinals. The whole whitepaper was uploaded just on 1-of-3 multisig outputs, see transaction 54e48e5f5c656b26c3bca14a8c95aa583d07ebe84dde3b7dd4a78f4e4186e713. You have the whole altcoins that are connected to Bitcoin by using part of the Bitcoin's UTXO set as their database.
That means, as long as you won't solve IBD problem and UTXO set growing problem, you will go nowhere, because if you block Ordinals specifically, people won't learn "this is bad, don't do that", they could read it as "use the old way instead", as long as you won't block all possible ways. And doing that, requires for example creating new nodes, without synchronizing non-consensus data, like it could be done in "assume UTXO" model.
Also note that as long as people use Taproot to upload a lot of data, you can still turn off the witness, and become a pre-Segwit node. But if you block those ways, then people will push data into legacy parts, and then you will need more code to strip it correctly. The block 774628 maybe contains almost 4 MB of data from the perspective of Segwit node, but the legacy part is actually very small, so by turning witness off, you can strip it to maybe just a few kilobytes.

1. Without a soft-fork, those data will be pushed by mining pools anyway, as it happened in the block 774628.
2. Adding some settings won't help, as most people use the default configuration. For example, people can configure their nodes to allow free transactions, without recompiling anything. The same with disabling dust amounts. But good luck finding a node in the wild that does anything unusual.
3. This patch produced by Luke Dashjr does not address all cases. You could use "OP_TRUE OP_NOTIF" instead of "OP_FALSE OP_IF" used by Ordinals, and easily bypass those restrictions. This will be just a cat and mouse game, where spammers will even use P2PK, if they will be forced to. The Pandora's box is already opened, that fix could be good for February or March, but not now.

Unlike other methods, such as using the op_return field which could also be used to spam the chain, the associated fees and the standardization rule limiting op_return to 80 bytes have so far prevented similar abuses.
Although attempting to stop inscription could lead to more serious issues, not taking action against these inscription could be interpreted by spammers as tacit acceptance of their practice. This could encourage more similar spam attacks in the future, as spammers might perceive that the Bitcoin network tolerates this kind of behavior.

I understand your point of view. However, inscription represent by far the largest spam attack due to their ability to embed themselves in the witness with a fee reduction.
Unlike other methods, such as using the op_return field which could also be used to spam the chain, the associated fees and the standardization rule limiting op_return to 80 bytes have so far prevented similar abuses.

Because it will lead you to never ending chase. You will block one inscriptions, and different ones will be created. Now, they are present even on chains, where there is no Taproot, or even Segwit. That means, if you try to kill them, then they will be replaced by N regular indistinguishable transactions, and then you will go back to those more serious problems under the hood: IBD time, and UTXO size.

The community also rejected things like sidechains, and they are still present, just in a more centralized form. There are some unstoppable concepts, for example soft-forks. You cannot stop a soft-fork. What inscription creators did, is just non-enforced soft-fork. They believe their rules are followed to the letter, but this is not the case, as you can create a valid Bitcoin transaction, that will be some invalid Ordinals transaction (because their additional rules are not enforced by miners and nodes).

Hello,
I am writing to you today because I am concerned about a significant bug that seems to be overlooked in recent versions of the software. The bug in question concerns the "inscriptions" developed by @rodarmor, and it worries me because, in just a few months, they have already reached a size of 11.8GB on the blockchain, causing issues with the UTXO set, which appears to be growing by about 25MB per day.
I understand that there may be discussions about the nature of these inscriptions, but personally, I find it hard not to consider them as spam. Their recurring nature and their impact on the size of the UTXO set and the blockchain itself seem concerning, and I would like to understand why this problem has not been addressed more seriously.
I would also like to point out that there are options in Bitcoin Core to choose the mempool policy, such as datacarrier or permitbaremultisig. However, when it comes to inscriptions, there are no available options except for a patch produced by Luke Dashjr. Unfortunately, this patch is unusable for most people as it requires compiling Bitcoin Core.
So, I wonder why there are no options to reject inscriptions in the mempool of a node. Such a feature could give users the ability to customize their approach in managing these particular cases and help mitigate the negative impact of inscriptions on the network.
In addition to the technical issues, I also find that this situation raises ethical questions. Inscriptions are primarily used to sell NFTs or Tokens, concepts that the Bitcoin community has consistently rejected.
Therefore, I kindly request you, as Bitcoin developers, to take this concern into consideration and seriously consider implementing a feature that would allow users to reject inscriptions in the mempool. Such a measure would contribute to protecting the integrity of the network.
Thank you sincerely for your attention to this matter.
Léo.
