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.

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?

OK, Here's a more elaborate picture:

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.

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.

So did mthcl and CfB already fix this vulnerability:

This is the scenario I'm talking about. Green filled, black edged are transactions of the honest network. Red edged - are transactions of the attacker. The doublespends are filled with yellow.
As far as I understand your algo, weight of the red tip is greater by 3 than weight of the green tip.

?

Why would the weight of the red tip be greater (not saying it can't be) ? Afaik tips only have their "own weight" since they are tips and therefore haven't "inherited" any weight yet. Which afair means that their weight depends on the POW of those tx (tips).

It was already discussed several pages earlier.

But the cumulative weight of that tx is not so big, so why the merchant should accept it?

NP, the merchant waits of course for normal amount of confirmations.

On your picture it has 1 confirmation only?..

I can draw more pictures. But I don't think it's necessary. Imagine that the attacker started preparing for the attack a month ago. He spent the whole month to accumulate PoW on top of the second doublespend. He published no transactions during the month. Then he publishes the first doublespending transaction, provides the first confirmation, thus attaching it to recent part of the tangle, waits for the merchant to send him his puchase. Then publishes his secret subtangle and attaches in to the legit subtangle. The first doublespending transaction now is rejected by the network, the second doublespend has more weight.

He would have to attach it "below" the merchant's tx, but yes, you're right, it's a possible attack vector. Anyhow, the referencing algorithm is not yet finished, so we are discussing it with CfB right now.

show all investor why you need 21 thousands btc?

You don't need them to tell you why. You can figure it out yourself according to your own daily life.

Btw, 21K is just an analogy. The more the better for the projects.

Edit - the investors will decide how much they will get. They have to sell it very hard to get an ideal number.

Some investors here trying to set a max cap for ICO (5000 BTC) or the maximum amount which other investors can send (500 USD). They think that this will affect their RoI.
They are wrong. Crypti set the maximum cap for itself as 750 BTC and is in deep shit now. Ethereum has gathered 30 000 BTC and it's investors made around x6 RoI.
So the key to good RoI is not low max cap for ICO.

This works well for NXT raised only 21BTC. Cheesy

Helps if you are only 5 people owning 99% of all coin so you can pump it at will when you need money..

so you should surprise why NXT sitll not die? lol

The problem is what Iota team can achieve with 21 btc. Can they work on Iota and Jinn full time to make the projects big and successful with 21 btc as their resources for themselves and their families? To make the projects big, real, and successful they need 21 thousands of btc.

show all investor why you need 21 thousands btc?

@CfB, @iotatoken-

A suggestion-

If you want to attract new and serious buyers and investors, you should create a Team page on you website to show the resumes and photos of your team member like Augur does - http://www.augur.net/

This is the way for you to tell people you are serious and determined about and confident on your project. Time has changed in the cryto world. Good resumes and real persons with photos and real names are the wise things to do.

have a look at tilepay.org,or their bitcointalk thread:https://bitcointalk.org/index.php?topic=761852.0

No copy. How is this anything like Tilepay other than similar market?

but light blockchain is smart chiose
