@Barabazs_@L0laL33tz It's not just theoretical. Chainalysis (and others) have been doing this for a very long time.
You can give them a tx hash and they can do a simple db query to see which node broadcasted it (with high accuracy).
Using your own node to submit a tx 100% doxes you.
The imminent constitutional law argument over executive powers to shutter agencies (like USAID) may actually be a pretty close call and a fascinating area of administrative and separation of powers law.
The Foreign Assistance Act of 1961 mostly just empowers the president to do things at his will, like create a dedicated agency for foreign aid. It generally does not obligate him to do specific things. Yes there are some aid packages that he is obligated to provide (because of appropriations) but I'm not sure they must be provided through a particular process or agency (like USAID). That's where the heart of this legal question will ultimately sit.
It's all rather similar to the statutory authority for foreign sanctions (which is my area of expertise) the president is empowered to sanction people but the details of exactly how and when (and whether he should do it at all) are often (though not always) non-obligatory and left to his discretion.
For me, both of these statutory schemes, and many more, are clear examples of why we need to revive the non-delegation doctrine of our constitution. Congress should make law, not the president. Where Congress delegates lawmaking authority to the president by writing highly discretionary statutory schemes (the president may do x,y,z, or nothing at all) without clear limits and obligations, the whole system becomes hyper-partisan and prone to wild swings in policy as administrations come and go.
This isn't partisan. The party out of the White House typically laments and attacks executive discretion while celebrating and expanding it when they are in the White House. The American system should do better than this ceaseless war between factions, and the Court should be in the business of simply striking legislation that hands too much lawmaking power to the president.
@LefterisJP Cypherpunk future: Your locally-run LLM will diagnose you and prescribe you medicine. You'll buy the medicine on a DNM using a privacy coin.
@phildaian Honestly, just "stop using phones" period (if you can).
Smartphones are exceedingly good at stealing every liminal moment in your life, irrespective of your operating system.
@LefterisJP@atris_eth@Narodism I think this answers your question as to why the free market hasnβt solved this. The doctor positions are in the public sector, not the free market sector.
@zooko@garious14@drakefjustin I think the reason is that Groth16 proof sizes are super small (like, tiny) so it doesnβt cost much gas to verify them via smart contract.
@zooko@GiacomoFenzi@drakefjustin Iβve looked into verifying Halo2 proofs with Ethereum smart contracts, but the proof sizes in Halo2 are much too large to submit in an Ethereum transaction.
@pcaversaccio@KoolexC@adrien_lacombe Best practice for privacy is to use a public node that you only ever connect to over tor (or VPN is you canβt use tor).
Okay to use own-node to read from chain, but should never use own-node to broadcast your own txs.
@pcaversaccio@KoolexC@adrien_lacombe Using own-node is approx *guaranteed* to DOX you. Chainalysis (and others) run nodes that collectively connect to approx all nodes on the network, and record from which nodes they first see a tx broadcast, thus revealing with high prob from which node the tx originated.
