Consider a timestamping service that's based on mathematical proof instead of social proof.[0]
But I agree, most often blockchain outside of a cryptocurrency doesn't make sense. This use case also depends on the security of an existing cryptocurrency.

- RL_Quine 7y agoDecentralized timestamping is literally what Bitcoin is, there's no other way of describing it. Ordering transactions canonically is timestamping.
- lawn 7y agoMy point is that you can leverage this by inserting extra data on a transaction, so you can timestamp any message.
- zelly 7y agoA cryptocurrency is basically a timestamping service. This was mentioned in the original whitepaper. > The solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post [2-5]. The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it. https://bitcoin.org/bitcoin.pdf https://bitcoin.org/bitcoin.pdf
