@node @silverpill Browser wallets are probably not critical to Monero adoption. A nice thing to have, but not critical. Smart contract coins like ETH have them. Browser wallets are usually considered to be less secure. Monero devs are working on privacy and scalability improvements to the protocol itself.

On BTC "Ordinals": Blockchains are permissionless data storage devices. Did you know that researchers permanently embedded hundreds of megabytes of non-transactional data on the Litecoin blockchain?"We present results from UWeb experiments with writing 268.21 MB of data into the live Litecoin blockchain, including 4.5 months of live-feed BBC articles, and 41 censorship resistant tools. The max-rate writing throughput (183 KB/s) and blockchain utilization (88%) exceed those of state-of-the-art solutions by 2-3 orders of magnitude and broke Litecoin’s record of the daily average block size."Recabarren and Carbunar (2022) "Toward Uncensorable, Anonymous and Private Access Over Satoshi Blockchains" https://petsymposium.org/popets/2022/popets-2022-0011.php

@hyc @HalvarFlake I gave the Bitcoin Cash node developers statistical power calculations (to determine appropriate sample size for high-load computational performance) and they thought it was overkill 😶 : https://bitcoincashresearch.org/t/assessing-the-scaling-performance-of-several-categories-of-bch-network-software/754/31

@filippo @tedted "Don't roll your own cryptography" is an accepted guideline in software development. When will "Don't roll your own statistics [especially when user #privacy is potentially at risk]" be accepted? Most software developers and computer scientists only know enough #statistics to be dangerous. Have a statistician review this Go telemetry proposal. https://github.com/golang/go/discussions/58409

In about 19 hours the Monero Research Lab will discuss a proposal to remove or restrict tx_extra in #monero transactions. tx_extra is a free-form data field in every Monero transaction. This conversation began many years ago, but it has become more salient now that Ordinals and Inscriptions have appeared on the BTC blockchain.Reasons for removing tx_extra: It could bloat the blockchain and reduce transaction uniformity, which is important for privacy and fungibility.Reasons against removing tx_extra: Major changes to transaction format in the future would require a network upgrade (hard fork).Monero community members can participate in the discussion at the text chat meeting:https://www.reddit.com/r/Monero/comments/112efzm/removing_or_restricting_tx_extra_will_be/

The U.S. Chamber of Commerce, the largest business association in the world, has an informative article for merchants about the pros and cons of accepting #cryptocurrency as payment: https://www.uschamber.com/co/run/finance/accepting-cryptocurrency-as-paymentThe article's subheadings:- Cryptocurrency offers better payment security- Cryptocurrency transactions are irreversible- Pay lower fees- There are tax implications- It’s still considered extremely risky

Is there any way to show (probabalistically) that a given byte sequence is encrypted instead of plaintext when the keys are not available to the verifier? Other than diehard-style statistical tests? #Monero is considering ways to restrict the use of the tx_extra field in its transactions.@matthew_d_green @socrates1024 @str4d or @filippo may know.

@molly0xfff There is already a paper about this: Wang et al. (2022) "BBARHS: Blockchain-Based Anonymous Ride-Hailing Scheme for Autonomous Taxi Network" http://dx.doi.org/10.1155/2022/8296608 ABSTRACT:In the past few years, ride-hailing platforms such as Uber, Waymo, and Baidu have built their own autonomous taxi system. Unlike public transit services, ride-hailing platforms raise severe privacy issues. To provide excellent autonomous taxi service, some significant security and privacy problems must be addressed. In this study, we present the security and privacy threats and first proposed blockchain-based anonymous ride-hailing scheme (BBARHS) for autonomous taxi network. We give the formal system model and security model of BBARHS. Then, we outline the concrete BBARHS scheme by making use of Monero and some efficient crypto tools. Through security analysis and performance analysis, the designed scheme is provably secure and efficient. The analysis results also show the designed BBARHS scheme is practical for autonomous taxi network.

@chelseakomlo Monero would probably prefer that threshold multisig and single signatures appear to be the same to reduce any kind of transaction fingerprinting.

@chelseakomlo Maybe I'm not understanding. Multisig transactions are used for escrow often. No potential signer is necessarily acting maliciously since that's not the Nash equilibrium to do so. Under conditions of real behavior, you don't necessarily have to design for every strategy, especially when an occasional non-equilibrium strategy in the wild would just cause a statistical dent in privacy rather than an all-or-nothing failure.In game theory, the mere existence of an option can influence the best strategy even if that option would never be taken by players.

On January 19th I released research showing mining pools were delaying the first confirmation of #Monero transactions by a full minute, on average. I said the delay could be eliminated if pool operators changed their pool software configurations to update the block template more frequently.I have good news: Most major pools did exactly that!I continued to collect transaction confirmation data after the release of the initial analysis. The average time that a Monero transaction has to wait for its first confirmation has fallen from 3.5 minutes to 2.5 minutes. That's a full minute improvement in less than two months! More info and graphs:https://www.reddit.com/r/Monero/comments/11nu4aj/monero_transaction_confirmations_are_now_60/

@silverpill @ademan Yes: https://moneroresearch.info/index.php?action=resource_RESOURCEVIEW_CORE&id=95kayabaNerve's comment was "Unfortunately, this relies on transaction chaining, and therefore is not applicable to Monero despite its intent (without a hardfork which does enable transaction chaining, such as the eventually planned Seraphis upgrade)."@ademan : There is no known way to make Payment Channel Networks private, even with Monero (see the paper below). The authors of the MoNet paper have not communicated with anyone involved in day-to-day Monero development and research. There are other payment channel proposals for Monero by the way.Tang, W., Wang, W., Fanti, G., & Oh, S. (2020).

@monerobull @main IMHO, the relay rules will not do much to stop Monero NFTs without a hard fork. The transactions propagate by a gossip protocol. If at least one of a node's peers accepts the rulebreaking transaction, and then one of _that_ node's peers accepts (and so on), then the NFT transactions would still get to the miners who do not upgrade to the latest node version. Then the block is mined and all nodes accept it since the tx_extra limitation is not a consensus rule.Even at the August 2022 hard fork, about half of all #monero nodes did not upgrade to the hard fork node version.

@monerobull There is nothing specifically planned AFAIK. If there is enough reason for Monero to hard fork, then it could be done. For example, if Bulletproofs++ is properly reviewed and implemented, better decoy selection, e.g. avoid coinbase outputs, discretizing fees (Seraphis does this, but it can be implemented independently), etc.

@Nerd_mister Even Monero nodes that have this update will store the large tx_extra data when they are confirmed on the blockchain. The update just allows a node to choose not to relay the transaction to other nodes before they are confirmed.

I performed data analysis to measure how Mordinals (Monero NFTs) can reduce #monero user privacy:https://www.reddit.com/r/Monero/comments/12kv5m0/empirical_privacy_impact_of_mordinals_monero_nfts/TL;DR: Mordinals can reduce Monero user privacy when their transaction outputs are included in normal transaction ring signatures as decoys. Just before Mordinal minting spiked, the P2Pool decentralized mining protocol upgraded to make their payouts more efficient, diminishing the net effect of Mordinals. Average effective ring size fell to 12.5 at its lowest point. Nominal ring size is 16.

@Korro Yes. There isn't a completely effective way to prevent arbitrary data from being stored on blockchains. Monero is a permissionless system. The Mordinal creators didn't need to ask anyone's permission to start sending their transactions.
