Adding onto @chytrik answer, the "proof" that it's impossible to find such a hash is purely probabilistic; perhaps there is some transaction hash which by sheer mind-boggling coincidence would not be hashable with all the others or any nonce to find a block with the necessary difficulty. If we supposed that this were the case, the next question would be how ...

I think that the answer to your question is no, a transaction which makes every block it is included in invalid does not exist. An important core property of a cryptographic hash function is that there is no discernable relationship between the input data, and output data. If such a relationship existed, then miners could 'cheat' by only creating blocks (...

URI schemes for various altcoins are not always formalized (although, ripple's has a draft). As such, many exchanges simply try their best to remove any doubt, especially when dealing with QR codes (to try and prevent cases of LTC being sent to BTC addresses and similar). This is usually done by prefixing the currency before the QR code, likely inspired by ...

This has nothing to do with BTC, and i'm quite unsure what you're asking or what's going on. Question is: is it normal to have ripple in an address? Why would it be there? Are you aware that XRP requires a minimum fee of 20 XRP per adress?

Yes (temporarily), but doing so would require a 51% attack, preferably just after the difficulty has been adjusted (at 51% the mining time for you would be an average of ~9:30 (9 minutes and 30 seconds) until the difficulty change which would happen in about a week in this case or another miner with a relatively small amount of control (2% would be fine, but ...
