"Nonsense. The purpose of the OP_RETURN on release was just to abort script execution with a failure to make an output provably unspendable. The sad fact that the consensus rules accept up to 1MB of arbitrary data after it wasn't discovered until years later and the opcode wasn't officially repurposed for embedding very small chunks of arbitrary data until 2014. The rationale at the time was to stop people from encoding data in bare multisig addresses.

"According to both Core and Knots documentation (or lack thereof) inscriptions are pure Bitcoin script (code) and OP_RETURNs pure arbitrary data.

"Can you elaborate on this I'm definitely excited about all of the free-market ways we can solve mining centralization. Look into NiceHash. It's basically a service where you can use bitcoin it to pay for a certain amount of hashrate delivered over a certain period of time and you point it anywhere you want (a pool or your DATUM Gateway). I think the future of mining will look like that if bitcoiners understand that its up to them to hash to maintain the system. The market will split into hash providers that will sell it on the open market and hashrate buyers (bitcoiners). Hosting companies"

"Remember the arbitrariness of the Samourai and Tornado Cash devs prosecutions.

"I don't share this narrative. The onchain network is settling trillions of $ of value each year (even though we peaked in 2021). The public lightning network currently has 3750 BTC locked in it for a market cap of about $400M. For the LN to settle as much value as onchain did last year ($19.2T) it would need to settle 48300 times its own market cap in micropayments. Not likely considering that onchain is "only" able to settle XX to XX times its own market cap every year and some of its payments can be in the billions of dollars. Onchain sees a lot more usage than any L2 and its problems are"

"If you only learn one thing about the OP_RETURN drama make it this: The biggest threat to Bitcoin's censorship resistance is that the biggest pools stop mining on top of blocks found by anyone and start mining only on top of blocks found by a small cartel of pools. Another name for this scenario is XX% attack. Independent solo mining would not be possible anymore and you'd need to join the cartel and pass KYC to mine.
