Could you please direct us to details of your design so that we may
properly appreciate it?

Note that the key idea in Shardmap is not simply logging a hash table,
but sharding it and logging it as a forest of fifos.



Around 2 years ago, I looked at some details of the FS design and discussed the copyright issue with one of my attorneys.
Today, I would like to make the following (maybe closing) words before somebody says I would block a development:
1. In general, there is a copyright for every protectable work done by a person in the moment of its publication, but in practice it is hard to prove, specifically in such a technical case. I will not go into the legal details.
Said this, at least I reject my claims, but still think that generally it would by a constructive measure if even ideas are referenced in relation with open source hard- and software.
In my case it led to the situation that I have stopped to publicate ideas, with some very few exceptions.
2. In particular respectively from the point of view of the software design, the implementation is virtually what I have proposed (as well). Indeed, there are some interesting details and elegant paraphrases.
3. I think it would be interesting to analyze how well this FS works respectively to compare this FS with databases that implement something surprisingly similar.
