Show HN: Copy tweets to Bitcoin's blockchain for $9
- zocoi 8y agoWhat is the size limit other than a tweet? Can it be expanded to articles? Also why? If twitter is down then I don't have the transaction id to look up the content.
- ericb 8y agoWhat happens when bitcoin transaction fees spike again?
- Boxxed 8y agoThen it will cost more.
- erentz 8y agoClearly BTCs on chain transaction fees are way too low right now.
- kang 8y agoFREE method! - add @otsproofbot to your messages - the bot will reply with a message with text and embedded proof. - superior tech than OP
- n3d1m 8y agoAnd the point of this is?
- tyrust 8y agoAnswered in the "Why?" section of the website link on which you are commenting.
- analogmemory 8y agoAre there tweets out there worth archiving?
- tekproxy 8y agoYes.
- n3d1m 8y agoRead the why section, still makes no sense. So many other ways to archive tweets without cluttering the bc blockchain. It just sounds like it would be cool to do without actually value.
- pavlov 8y ago"And on the blockchain, these words appear: My name is @ozymandiazz420, Independent Thinker; Look on my Tweets, ye Mighty, and despair!"
- nathell 8y agoThe lone and level bytes stretch far away.
- nodja 8y agoQuite a cash grab. 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. https://memo.cash/protocol https://memo.cash/protocol
- AlexCoventry 8y agoWhat fraction of miners accept non-standard transactions like this?
- malvosenior 8y agoOP_RETURN is standard. So all of them.
- AlexCoventry 8y agoIt's part of the standard, but atypical and consumes block space. So there would be less incentive to include such transactions.
- stale2002 8y agoIf you pay the fee, miners will accept it. The miner doesn't care about wasting blockspace. It is simply an auction, where the highest payment per byte wins.
- malvosenior 8y agoAs far as I'm aware, all mining software (including Bitcoin Core) support it.
- TazeTSchnitzel 8y agoDoes the service not restrict this to your own tweets? This could be a harassment tool potentially…
- gkoberger 8y agoHow? It's not like you're creating a billboard out of it... it'll be buried in the blockchain, and nobody will ever see it (unless you link to it). What makes you think this could be used for harassment?
- lallysingh 8y agoRecording something that someone puts on a public 3rd party doesn't seem like harassment. But maybe I'm missing something. How would the harassment work?
- marcoperaza 8y agoThe ability to store arbitrary data on these widely replicated blockchains raises some serious legal questions. What if someone puts illegal information on the blockchain (e.g. nuclear secrets, child porn)? 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.
- vortico 8y agoInteresting question. For Bitcoin it would be difficult because of the small amount of data (except for maybe 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0), but what about i2p, IPFS, etc?
- philipodonnell 8y agoThere is a cost, but larger pieces of data can be broken into chunks and stored on the blockchain. Some types of data are considered breaking the law to possess it, regardless of whether it was intentional or how it was acquired. 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.
- dane-pgp 8y agoThose questions are very thought-provoking, and here are a few more: * 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?
- m00dy 8y agoUsing OP_RETURN values is a neat idea. I wrote a thesis long time ago. (Using Bitcoin Blockchain For Fun and Profit) http://www.diva-portal.org/smash/get/diva2:1051913/FULLTEXT01.pdf http://www.diva-portal.org/smash/get/diva2:1051913/FULLTEXT0...
- rosstex 8y agoCool!
- mpfundstein 8y agoGDPR anyone? lol
- zachgray 8y agolol yeah, gonna make for an interesting court case in 2030 when someone cant scrub some heinous tweet from the blockchain :P
- codetrotter 8y agoCool concept but also very nice logo. Who made that logo?
- iampims 8y agoA while ago, I built a prototype that did something somewhat similar with IPFS instead of blockchain. It also pinned the IPFS object automatically. It saved the entire tweet minus all mutable attributes (user info, retweet count, etc). I didn’t think of using a twitter bot for archiving, that’s clever.
- bevan 8y agoPeepeth.com lets you "Peep" on the Ethereum blockchain for much less. Disclaimer: I am the creator.
- ClassAndBurn 8y agoReally $9 for infinite storage is a deal.
- guiomie 8y agoI wish I could think of clever things like this.
- rajeshpant 8y agoThanks, i'll take a screenshot and store in google drive.
