ICO is expected? Or what options will be available to early-stage investment?

I think ICO wil be held later this year before christmas.

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

It was already discussed several pages earlier.

We agreed that my picture shows a successful attack vector. Your picture shows an improbable case when a merchant accepts a transaction with very low confirmation score (no matter how many squares you'll draw keeping the same topology).

PS: Yes, mthcl fixed that issue.

More squares don't help here without an explanation why other green squares haven't been approving the legit transaction for long period of time.

I already wrote it earlier. Because it was not published for a long time, until preparation for the attack is complete.

So, the merchant sees a clear sign that his transaction hasn't been seen by the network for a long period of time and he still thinks that the service/goods should be provided without waiting for much longer?

You claim that your design allows mergers of split subtangles. The merchant sees something like that. Your algo, described in the whitepaper, shows good confirmation score. Do you want merchants to analyze the DAG manually?

No, of course. The software will do that.

So that's what I asked. Is there a fix already?

That is the same issue, which I beleive, mthcl and you admitted to exist.
If it's fixed, may we see an updated whitepaer?

Well, the issue was improbability of your picture because it had a sign of successfully conducted eclipse attack (if the transaction was published), that case was not what we were talking about. The discrepancy between the words and the picture made me argue, otherwise someone digging deeper would be confused.

Updating whitepaper is not that simple as typing few words, it will take some time.

Eclipse attack is irrelevant to this scenario. The attacker only needs to delay publishing some of his transactions.

I thought we were talking about the standard case of a non-delayed transaction issued by an up-to-date node. If you do delay a transaction then the picture has the same profile as one with an eclipse attack.

Here:  http://docdro.id/CXDq93a

Upd.: in (1), there should be exp in the sum as well (so that the transition probabilities sum to 1). Already uploaded the corrected version to docdroid.
