Merge-mining the CryptoSphere with Bitcoin

[Ron Gross]

I just found this project today, and it sounds very promising.

It sort of answers a question I asked some time ago.

Are there (long-term) plans to do sort of a "merged mining" of the cryptosphere using the standard Bitcoin blockchain? (Like with Namecoin) 

The goal of this is having a very strong proof of the timestamp of posting data into the CS.

The user story:

Suppose the CryptoSphere is not yet wildly adopted, but is rather a hobby project running on 10 home computers.

I want to store some data in the sphere, and I want this fact to be verifiable later in court.

Maybe I want to store an invention I did until I develop it, to prove later that I was the original inventor.

Bitcoin is the most secure source I know today for timestamp verification. It is not feasible to alter the long-term history of the blockchain.

Without using Bitcoin, I'm not sure there's a good, cryptographic way of doing this.

"Merged mining" is a concept, implemented in Namecoin (a Bitcoin fork), that addresses the problem of verifying a "weaker" coin using a "stronger" one (we're comparing hash rates).

I believe the CS can use this concept to answer this design goal relatively easily.

Thoughts?

That's an interesting use case, although probably not something I want to tackle right away

Yeah, I agree it's definitely not the first use case to tackle ... just something to keep in mind for the future.

BTW, what is the first use case you thought about?

The main use cases I have in mind are:

- Personal backups

- Dropbox-style file sharing

- Anonymous web publishing (e.g. what you're describing)

- Encrypted anonymous source control

Perhaps this should be added to the readme.
