Just use the memo.cash protocol and put it on the bitcoin cash blockchain for a fraction of the price (you just pay the BCH transaction fee). You're limited on the message size but the May 15 blockchain upgrade will increase the OP_RETURN limit and put the limit slightly higher than twitter's.
- add @otsproofbot to your messages
- the bot will reply with a message with text and embedded proof.
- superior tech than OP
superior tech is absolutely laughable - you're storing tweets to a private and centralized database somewhere.
OP's writes them to bitcoin's distributed ledger where they are public and permanent.
Even if some level of mens rea is required convictions, that is usually set at "reckless" (meaning that you were aware of the risk but acted anyway). Once there's a high-profile child-porn-on-the-blockchain case, it would be very hard to argue that you weren't at least aware of the risk that such information might be there. Even if the mens rea requirement is "knowing", that will still be a problem, as bitcoin miners and other savvy cryptocurrency actors would have a hard time claiming ignorance of the immutable nature of the blockchain.
Can data broken up like that can be said to be in your possession if it is never recombined? What if you don't know how to recombine it but a prosecutor does? What if it is known to be recombinable but no one knows how to recombine it?
Most blockchain people I talk to are worryingly dismissive of this as a potential issue, including lawyers.
* What if someone with access to your house/bag/coat slips in a Micro SD card with an illegal file on it?
* What if you download a large video file as a torrent and it contains an illegal file embedded steganographically within it?
* What if your computer is storing a large, possibly random-looking, file, and someone can produce a "one time pad" which, when XORed with that file, produces an illegal file?
> Based on these insights, we conduct a thorough quantitative and qualitative analysis of unintended content on Bitcoin’s blockchain. Although most data originates from benign extensions to Bitcoin’s protocol, our analysis reveals more than 1600 files on the blockchain, over 99 % of which are texts or images. Among these files there is clearly objectionable content such as links to child pornography, which is distributed to all Bitcoin participants.
POINTING to the exact digits of pi, and telling the audience the decoding method, that points to thr illegal porn, or content would get you in trouble though.
It just sounds like it would be cool to do without actually value.
I didn’t think of using a twitter bot for archiving, that’s clever.
What makes you think this could be used for harassment?
The miner doesn't care about wasting blockspace. It is simply an auction, where the highest payment per byte wins.
