So you have no more goals set for now?

It's the main one.

does your confidence ever waver at all regarding the technical challenges faced in this project?

So far I reached every goal that I set (and had time for that), there are no evidences that this project will be different. Though it still can fail due to market competition.

Guys, be gentlemen. Or you may feel yourself not very comfortable when meet each other in person during the gathering of Jinn investors in Burj Al Arab. :)

XEM price declined to 70 sat. Why?

Edit: Never mind, I recalled about TooCoolForSchool.

Do you mind to share the cause?

TooCoolForSchool's pictures worked.  ;D

BTS price is declining, I'm curious why.

Edit: I figured out it, never mind.

Nxt General Discussion / Re: Maximum block size is too restrictive
« on: April 09, 2015, 09:45:28 am »
Right, the paper https://eprint.iacr.org/2014/765.pdf shows if block generation time becomes close to block propagation, it's not 50+% security anymore, but 33.(3)%. Nxt is about the same.

That paper analyzes cryptos with unbounded membership (of forgers) and without Transparent Forging. TF extends tolerated latency from 60 (110) sec to, say, 300 seconds, because even in 300 sec we still can predict the sequence of forgers with reasonable probability. You will see this in your modelling when you start analyzing behavior of the system when 34% of forgers send incorrect data trying to fragment the consensus. Surprisingly, with TF 34% is not enough for a successful attack.

There is one other problem with increasing the block size, and this is that even if you make the data prunable, the time it takes to download a block needs still to be small enough to allow for quick fork resolution. If we have 1 MB blocks, and you need to download 10 blocks in order to switch to a different fork, and this takes you more than a minute to download 10 MB, only to find out that it was the wrong fork, but the next block came out already and you missed your turn to forge, etc, clearly those on a slower internet connection will have a problem. Therefore even with the prunable data I am implementing now, the block size will stay the same. In order to increase the block size (with prunable data), we would need out-of-band download of that data, so it is not only prunable but also "optional", i.e. does not need to be downloaded as part of the block, but later, when fork resolution is complete, the correct fork is known and it is worth spending time downloading that data in the background.

Can fork resolution be done in advance (by utilizing TF)? First ask headers and transaction hashes, then pull transactions that are unknown to you.

Tomorrow we will launch v0.2.0 alias Chronos. It will contain DPoS and therefore the blockchain will be restarted. For this you shouldn't do any transactions after 7:00 AM UTC, until we give the OK. Else you are in the old v0.1.9g fork.

Everything else you need to know is on our forum. http://forum.crypti.me/viewtopic.php?f=3&p=25#p25

You copied DPoS without any changes?

Wow wow wow.
I bow down before you.
That is so smart!

Will this be applied to all message attachments not exclusively AM?

There is no benefit to hash transactions that affect effective balance for an obvious reason.

And 10 months of test net and well over 2 million transactions were... ?

They don't contain real incentives.

In the early days (through the lens of my understanding), you spoke of Nxt 'hubs' doing most of the forging as these would have the resources to process the transactions and resist DDOS. I thought Hubs = forging pools, now I think it might have more to do with economic clusters.

This would be more like Ripple/Stellar, but with enough nodes then it would 'look' decentralized'?

https://bitcointalk.org/index.php?topic=1002703.msg10910353#msg10910353

Hubs are just pools. It's not related to EC.

Bonus marks for using initiative?

What can we call the problem that solves the 51% attack, if not Byzantine Generals? Does it have a name?

No idea. Cryptos lack good terminology.

Is this widely believed/common knowldege or something you found from your work/research?

I knew you'd bite ;D ;D :D

I saw you say as much before and your the only one I've seen say this. This is why you say bitcoin (and presumably Nxt?) are susceptible to 33% attack rather than 51%?

Can you briefly restate the reasoning? I don't think we have a thread on this, just snippets scattered around.

Byzantine Generals are vulnerable to 1/3 of traitors or not vulnerable at all. If a cryptocoin has 51% (not 33%) attack then it solved another problem, tertium non datur.

Neither.
