On the 2nd April we changed to phpBB as our forum software. With this we started using a very nice and Crypti-like theme for the forum. I hope you liked it so far.

A few minutes ago I updated the theme at some aspects. It should now follow the material design guidelines a bit more. As you probably know we went with the material design at our Crypti client, and using it as our corporate identity from now on. Smiley


I hope you like it! Smiley

An Introduction to our Multi Signature Implementation


Hello readers,

We are back with another Crypti issue on Thursday, and today we will cover the upcoming multi signature functionality in Crypti v0.3.1. We will explain how it works and how it will look like.

A multi signature account with a 2nd passphrase, will make your Crypti account as secure as a Swiss bank. There are few cryptocurrencies with multi signature support, and soon Crypti will join their proud ranks with an innovative twist. This is very important for exchanges, as they can offer a nearly 100% security.

Second, I totally agree about the vulnerability of Crypti in its current form to DDoS attacks.  As I have discussed before, one solution is to split Top Delegate communications with Lite clients and their communications with each other onto separate IP addresses.  Top Delegates should have their own darknet where only they know the IP addresses being used for communications to new forge new blocks.


I have my concerns with this. If only 101 delegates have control over the network, it will be very simple to launch a coordinated attack on these. Are there any ways to handle this?

Right now you would have to DDOS all 101 delegates at the same time.  Failure of any delegate to forge a block, passes the block to the next delegate in line.  If 10 delegates were unable to forge, those 10 blocks would have been forged by 10 other delegates.  This 10 delegates would have forged 2 blocks for that cycle.   That would only marginally delay the current 6-10 confirms needed for a transaction to be confirmed.  

Since 10 blocks were missed, then passed on to other delegates, that cycle would lengthen by 100 seconds for the 101 blocks.  Cycle completions are used to check the block chain for forks, add/delete delegates to active/standby mode; and divide the transaction fees earned during that cycle, if any.  

In the future versions, it has been discussed that we will be dropping delegates from the 101 club after X number of failed forges, for the next X cycles.

The capability to do this is one of the advantages we got when we spun off Crypti Lite.

1) MacOS is unix.
2) standby delegates can store CBC-s.
3) Lite wallet is best for windows users. Professional servers are always running under linux/unix - best for 101 delegates.

Keep the good work!

Lite Wallets will be able to run Dapps, but not process them.
What is the difference? Huh

We will reveal more information in the coming weeks. Wink

Interesting Smiley I'll wait for more info.
I really like where Crypti is going. This is one of the few projects I believe in.


Thank you. For all believers, spread the word! Smiley

The foundation controls 11% of the votes, and the dev team has purchased another 20% of the coins since the IPO.  25% are in Bter, and another 20% are in other exchanges.  That leaves about 24% that is in wallets of inactive investors.  

I think these numbers are actually a little different, see : http://cryptichain.me/topAccounts

Bter is down to 18.5%, Foundation is down to 8%, Poloniex is 4% and Cryptsi deposit / withdrawal has been broken / frozen at under 1.5% for months (altho I still don't know its exact account number - can anybody supply that?).

Thus total exchange holdings are under 25% and two-thirds of all Crypti is currently in the hands of private individuals.



Those numbers dont look top bad. How about the part that the dev team controls? Together with the exchanges, that still totals to about 50%. Coupled with inactive people, this is a massive chunck.

The dev team, which is hardly a cohesive group, controls about 20% of the XCR..... most of which we all bought from exchanges or in the IPO.  Some of that is still on exchanges. 

We need the inactive community to get involved and start voting for delegates.

Crypty has been down since September.  I have several tickets sent in Sept 2, 2014.  I also have some XCR lost in transit from them that I still have not been able to recover.

One reason that the Stas delegates show low uptime is that the uptime is figured from the first block that the delegate forged.  In the case of stas, that is around 110,000.   we are now in 270,000 range.  Stas was offline for a few days due to a billing problem with Vultr.  Since he missed forging some 50,000 blocks, he dropped to about 14%.  It takes about 100,000 blocks for him to advance 15%.  He is forging around 100% now.

This is t change in version 021.  The uptime will be figured with the last X blocks.  Value of X is undecided, and depends on testing results.

This will be a valuable change and similar to what I proposed earlier about "current consecutive blocks missed" being a figure of merit that needed to be shown.  I still think this would be the best thing to show for making voting evaluations, not an "uptime" number that blurs this info by "averaging" it over "t".

Starik, if someone were to run a full node on windows and try to become a delegate, it would be pointless. As soon as they became a delegate and were active and started missing blocks, they would just get voted out.
If this is true and the network became only 101 delegates then this is very bad because it could be stopped by simple ddos attack. Cry

A few points.

First, stasDelegates 1,2,4,5,6 and 8 are below 25% uptime and still dropping.  They've obviously been offline for some time now and still haven't been voted down.  We've got six new standby delegates (cryptiNeo,starick69, btc, Intrinsic1, Intrinsic2 and China) waiting to get votes and replace them.

Mal,

In the past hour I brought this up to the group, and updated our internal list for voting/upvoting the foundation delegates.
