Prediction: headlines in 2040 will look like: - "EU bans sale of 'non-approved' phones and laptops" - "Australia cracking down on illegal computation" - "New 'client-side safeties' mandated for all devices produced for sale in USA" Governments can't tolerate our ability to circumvent them with code. The EU is already trying to force backdoors into E2EE messengers. Someday they will escalate to banning general-purpose computing hardware because it can do things they don't like: deepfakes, bitcoin, encryption, TOR. Draconian laws will never stop coming, but we dont have to stop them - We need only slow them down enough that we can out-engineer their weak-ass laws. Wanna help slow them down?

Anyone with STARK experience know how to build and validate a simple proof of secp256k1 discrete logs and SHA256 hashes? I know ZeroSync must be doing this as part of their blockchain sync proofs. But i'm looking for a self-contained way to build and validate the proofs in rust.

⚠️ Technical article ahead! I reverse engineered TicketMaster's rotating barcodes for fun and profit. They're actually very easy to pirate.

I'm now mostly convinced that the ordinals/inscriptions crowd just don't care about efficiency. I made some simple constructive suggestions which could save millions of dollars a year in wasted mining fees. All are being ignored.

Clever 'coiners cooperate instead of clashing. Forget fruitless debates about whether inscriptions _ought_ to be used or not. I want to start concrete technical action to reduce the burden of inscriptions on the bitcoin mempool and fee market by going directly to the source. We should be spending our effort streamlining the actual apps and protocols which are pushing all this data into the mempool in the first place. Who wants to help?

I can see #inscriptions are causing a lot of debate in the Bitcoin community, particularly regarding whether they should be "filtered" or "censored" at the mempool level by labeling them non-standard. I'm here to tell you that this moral/ethical tennis match is irrelevant. Inscriptions can be pushed to the blockchain invisibly, by disguising the data inside normal-looking transactions. The true plaintext data is revealed only after the inscription is mined. I call these, "Inviscriptions", and they cannot be censored without resorting to flimsy heuristics.
