He says he optimized their efficiency but he calls the more efficient ones linkable ring signatures.  Are our ring signatures linkable too?

The install script install_monero.sh created by David to build monero was throwing errors in Ubuntu 14.04 (also it's not on the new website). I added some minor fixes, now worked for me (only in Ubuntu 14.04, not tried other versions). Posting source:

Anyone have a tl;dr for Adam Back's post on ring-signatures: https://bitcointalk.org/index.php?topic=972541.msg10619684#msg10619684

He came up with a way to make cryptonote ring signatures about half the size (for larger rings; for smaller rings it is larger) and twice as fast to verify.

Is this something that could be implemented in XMR and would it be beneficial overall (due to smaller rings being larger)?

Yes it could be incorporated but its not something to jump into, especially given the modest gain. Any cryptographic scheme, even small modifications to one, needs a lot of peer review and scrutiny before being ready for adoption.

Now by contrast something that made ring signatures fixed (modest) size, that would be quite something. You still wouldn't want to rush into it, but studying it and carefully reviewing it would be a matter of more urgency.

Is this something that could be implemented in XMR and would it be beneficial overall (due to smaller rings being larger)?

You could make the moneroeconomy.com website look like the presentation-design. It looks very nice. I might be able to help, depending.

Hi there!

Today I came across blocks 457254 up to 457258 which seem pretty odd to me. They all contain many transactions with fees of 0.1 XMR for small size transactions, this one http://chainradar.com/xmr/block/457255 , for example, has 23 transactions with a fee of 0.1 XMR plus a couple of normal transactions, totaling ~2.34 XMR in fees for the block.

Any thoughts about it?

I can explain the 0.1 XMR fee easily enough. That is what happens if you haven't upgraded your wallet to the version with per-KB fees. As you saw, on small transactions, you will significantly overpay.

I can't explain why someone would generate so many transactions like that.

Don't know if someone already find it, but it seems to me that this thread

ring signature efficiency
https://bitcointalk.org/index.php?topic=972541.msg10619684#msg10619684

is worth sharing here.

To make a long story short Adam Back is speculating on how reducing ring signature used in cryptonote:

This alternate linkable ring signature tends to 1/2 the size of the crypto note ring signature as the signature is 3+n values vs 2+2n values.

I haven't the skill to validate his claims but I thought than monero devs would be interested in such a claim.
