> document on a Blockchain that you have first-hand knowledge that someone has committed a crime against you

Farting into a wind is about as effective with the difference of being free.

If someone wants to actually fight this, a dash cam streaming somewhere offsite and secure (cloud is fine) is a million times more effective. It provides direct, court-admissible proof of the claim in a way a personal diary entry, in a notebook or on a blockchain, never could. Barring that, an audio recording on your phone. (Would check your state and local laws first, however.)

The Blockchain part is the for the notary part. No one is going to store a video file or the relevant PDF files of sworn testimony on a Blockchain itself, and an S3 bucket is fine of course ; I would have already thought this was extremely obvious.

The notary part is absolutely essential. Renowned Blockchains are the ULTIMATE for this use case. Sorry that you didn't already know this and the other part wasn't already obviously to be assumed by you.

I thought I was posting on a site called Hacker News, I was obviously being too assumptive. I'll spell things out more elaborately in comments in the future.

A court could care less about blockchain hashes unless the society of lawyers and judges decide it is legitimate. Did they? Last I heard blockchain hashes were as useful as any random bunch of numbers on a printed page.

Notary service is an essential component to proceedings.

Courts have generally accepted proof of existence that is established by proper entries to robust distributed immutable ledgers.

More important than courts are the people. If someone many states over has a serious crime committed against them, and they want it to be known they have been wronged in some way, I and others have a moral right to know about it.

Those who know of an ill that has happened and choose to speak about it should be heard.

If someone provides testimony in the form of a video or a written statement, the files can be available over any medium such as torrent, R2 bucket, IPFS, what have you, but proof of existence on a blockchain for the authenticity aspect, "this exact thing identified by this sha512 hash submitted at this time" and unchangeable, is imperative.

The blockchain part is imperative so somebody can't "just go back and change something" post-facto.

If you want to see an example of a court action going a different way due to what was written to a robust distributed immutable ledger, do a web search for "Craig Wright is a fraud posted by private keys he said he owned".

That is the Satoshi Blockchain referenced to and swaying a court on a cosmic scale.

>> A court could care less about blockchain hashes unless the society of lawyers and judges decide it is legitimate.

Facts are not determined by loose consensus decided by private societies. The standard is higher. Such private societies are also not a substitute for the legislature, nor could they be for determining a true fact.

Blockchains and their contents are rooted in math so they're not trivial to argue with. USA is rife with academia suitable to provide abundant expert witnesses for said math.

In practice this would lead to the case being escalated to a higher court. Or worse a federal lawsuit could be filed against a judge, which is not unheard of.

Judges aren't cosmically ultimate arbiters, they take an oath and have a duty and like anyone else who does, they are subject to rules and regulations for which there are real consequences for failure to abide by.

I understand where you're coming from, but until the math is accepted by a court and a procedure for validating authenticty is established within the society of judges, the burden for introducing this kind of evidence falls on whomever decides it is essential enough for their case to succeed. That's a very expensive proposition, so you can't really say that it is the process until a plaintiff or defendent with large enough pockets to afford the conversion of the legal society takes up the cause. Until then it's just random gibberish, and unavailable to the average person as a court admissible statement of authenticty for a digital artifact. The fact is that the "loose consensus" of "private societies" DOES determine acceptability, when that private society is the law society. Judges are only subject to the rules and regulations that other judges and prosecuters decide apply. There's nothing cosmic about it - it is very much rooted in the people who apply the law.

		The case that Craig Wright lost was years ago. The evidence that was posted to the Satoshi Blockchain was recognized by the court. It's already happened. . >> Judges are only subject to the rules and regulations that other judges and prosecuters decide apply. The last thing a state judge wants is a federal lawsuit against him where a federal judge reviews accusations that he/she didn't follow essential procedure. . >> it's just random gibberish The plentiful expert witnesses from math departments and computer science departments from Harvard, MIT, Stanford, and the like who will gladly show up to defend their fields (albeit will want to be paid), would say otherwise, if that were necessary, which it's not, because like has already been pointed out at least twice now `it already happened.`
