> it only takes one determined spammer to make a tool to allow the less determined to spam. - @npub1zfyt...m60l This is the asymmetry that many filter proponents seem to miss. Most of the kind of transactions they wish to filter out are created using dedicated software (services / tools / platforms). Developers of such software can rapidly bypass any restriction using open source software like libre relay, which will get their transactions to miners. We already see this, with some platforms offering the ability to select broadcast method from a drop down, including direct broadcast to some miners.

Did you use the bitcoin core wallet in the last year?

@npub1hvw0...5e8q and I are arriving early for @BTC Prague. Get in touch if you are around from the 14th and want to meet up!

Which filter do you think core will drop / change the default for next? - Max Transaction Size - Minimum Relay Fee - Minimum Output Size

Block 900,000, had room to spare despite a celebratory meme inscription.

Unbelievable lack of use

41.65% of the UTXO set is dust amounts precisely at the implied default core policy dust limits for various script types. note: p2tr is the most popular 546 sat script type (68% of all 546 sat outputs). I guess degen wallets don't compute the actual dust limit?

Surprising facts from my new report on Bitcoin's UTXO set: - 49% of UTXOs are sub 1000 sats - 30% of UTXOs are inscriptions related - 100k+ 10-year-old counterparty UTXOs store arbitrary data with fake multisig pub keys Read it in full here:

By popular request, here is the last years bitcoin transaction data with rune & BRC20 split out from other OP_RETURN and Inscription transactions. Runes & BRC20 = 51% of transactions over the past 12 months

Over the past year bitcoin there have been more data storage transactions (inscriptions & OP_RETURN) than other transactions.

The most entertaining outcome is the most likely. Bookmark this.

Get yourself to a @btcplusplus event, what @niftynei() 🇺🇸💸🧡 and the team have built is truly special. The difference between online and IRL discussion is stark. Online we only see differences. IRL people celebrate similarities.

I’m seeing lots of speculation around the financial motivations with regards to modifying OP_RETURN standard core policy. In 2023 Peter Todd was transparent with his financial incentive ($1000 from Christopher Allen) for making pull request 28130, which was ultimately closed

🎲 In 2014 Luke Dashjr described mining policies such as OP_RETURN size limits as not being a development topic, and suggested randomizing the default value. https://gnusha.org/pi/bitcoindev/201411161724.19573.luke@dashjr.org/

The latest OP_RETURN war kicked off days prior to @btcplusplus mempool edition. very sus. In Austin to get to the bottom of this 👀

I've put some numbers together to help you determine whether the horse has already bolted regarding the use of bitcoin for non financial transactions. 49% the UTXO set is sub 1000 sat outputs 43% of transactions in the past 2 weeks had an OP_RETURN or were inscriptions.
