.. Which does nothing against a backdated article. What stops me from copying a NYT article and posting it to the blockchain a few hours after, claiming it's mine?
What makes the bitcoin blockchain good for this? The bitcoin blockchain is good for posting transactions within the bitcoin network and kind of a shitty solution for "a generic blockchain"
Why a blockchain at all? Why not just a merkle tree? Surely there is somewhere better than the bitcoin blockchain for this. CT logging isn't done on the bitcoin blockchain for a reason.
So sure, you can prove that something wasn't created after the date of the transaction (assuming you're using a CS hashing function), but for this to work in this specific context, you'd need every publisher to be posting transactions to this log.
If I post an article and post a hash to $genericBlockchainWhichIsReallyJustAMerkleTree, what prevents someone from copying, backdating, and saying that I copied them? That they didn't post to the log as well?
- dubhrosa 8y agoAgree that bitcoin blockchain is unnecessary, but isn't there some merit in the idea that all major publishers in a juristiction would opt-in to posting to a single chain? Given the potential legal cost savings it would seem to be at least somewhat feasible.
- cheeze 8y agoOh absolutely. But I don't know how much of a "blockchain" that really is depending on how you define it. When I think blockchain, I think miners/proof of work/etc. Is a CT log a blockchain? Because really what we're talking about here is a signed ledger which may be decentralized but very well may be centralized as well.
- staplers 8y agoYou should really educate yourself on the bitcoin blockchain and how it records time before making a fool of yourself by trying so desperately to dismiss it.
