SAFE Network Explained: Architecture


#21

I mainly wanted to point out the usefulness of automatic checkers. I stick to American spelling, because I learned English in the US, but I guess documents for Safenet should be spelled according to British standard. Of course one has to choose the desired dictionary in Word manually. The problem with Word is so many functions are active by default. The problem is with the settings - not the checkers themselves, if used correctly.

(I also localized Clippy, the famous Office Assistant that everybody hated, but that doesn’t mean I like the implementation of it.) :wink:

“Enpoints” would also have been picked up automatically.

I’m no authority on English, but I still think those abbreviations should have periods (full stops). When it comes to spelling, the important thing is to be consistent, I think.

Good and logical choice to use what is already out there and proven thoroughly.
I don’t know the finer technical details of sha3_256 (Keccak), but I see that Belgians are involved in its creation, so it can’t be that bad :wink:
Probably better then making your own hash function, like IOTA: https://medium.com/@neha/cryptographic-vulnerabilities-in-iota-9a6a9ddc4367

Exactly. This means that several mutable data having the same name but different tags can be uploaded in the network. They all will be stored in the same group of 8 vaults (the closest ones to the common name).

To avoid collisions with existing MDs having the same tag an application should use a random nonce concatenated to the source identifier and then hash the result to compute the name. This also renders the name unpredictable, which prevents an attacker or a competing app from squatting a name that the app will need in the future.

I share your concern about this. If all clients use a hash function to generate MD names then they will be uniformly spread in the xor namespace, which is good. But the problem is that apps are not forced to do that. I see a potential attack based on the creation a set of MDs having a specific name to overload a group of nodes in the network, for example to get control of a section by eliminating these nodes.

Won’t this only mean that in the worst case someone might be able to fill the hard disk space shared by some node(s) by creating lots of MDs with almost the same names, maybe just increase it by 1 bit every time, but then some other random(?) nodes should come and take their place?

Americanisation and Britishification of text is a challenge, even for those of us with a couple of decades in both countries.

Using tap instead of faucet, or boot instead of trunk just takes some getting used to.

The real tricky situations come into play when someone uses a word common to both, that means different things. The spell checker won’t fail it and eyebrows will raise - especially if you use fanny when you mean butt (or buttocks or bottom). It’s not the same part of the anatomy in Britain.

Just remember to splash in plenty of extraneous “u’s” and remove all “z’s” and your American English becomes British English, largely :wink:

Automatic checkers of spelling and even “grammar”, i.e. syntax, cannot and are not supposed to replace human knowledge and education. Just like a chainsaw is not supposed to replace the human holding it. But if used correctly, which takes some practice and studying in itself, the automatic checkers as well as the chainsaw can help humans in their work. Automatic translators will not replace humans in the foreseeable future either, but that doesn’t make them useless in all situations.

I have now actually read the article and would like to thank @mav again. A very useful article and a good read!

I wasn’t proofreading, but I happened to spot the following mistakes:
it’s -> its
"This causes it to leave it’s existing group and become part of a new group."
“The relocated vault must now store chunks that are closest to it’s new identifier”

Can we link or pin this somewhere where people can see it? Really awesome job on this one!
