No guarantee on this, but I think it's about 5MB every day. Remember, we have delegates, that means they will take care of the hosting. The normal user won't. So the few GB the blockchain will take, will mean NOTHING. Soon TB space is the standard.

It's just a collective of quick money makers now, thanks to the asset exchange and the open forum rules, with dozens of scams. Something need to change in that direction, or it will be a "tour-de-force" for NXT in the future.

They are still one of the most innovative coins out there. Others are standing still, while they are developing (even through in the wrong direction). But this thread is about Crypti.

a clean ubuntu, with crypti 0.2.0 client running, uses about 177MB of ram on my node.
blockchain size is about 50mb, and the first block is recorded at 2015/03/18 , making it about 20 days old. that roughly corresponds to 2.5mb per day, but this doet not take inital setup size or anything in consideration.

D'oh, I missed that change, thanks for enlighening me.  I have modded my post calculations above to reflect this 0.1% fee instead of 0.5% fee.  The new "bottom lines" repeated here are:  

For a Delegate to make "just" $10 in a month, the Crypti price has got to be 2.5X higher than it is now coupled with more than the entire total supply of Crypti changing hands every month.    

Another scenario is, if the monthly transaction traffic target is dropped to "only" 10M Crypti per month (a tenth of the total Crypti supply), then compensating a Delegate $10 per month requires a Crypti value of $0.112 each, or over X25 the current value.

As noted above, a delegate had better be prepared to fund a node out of his own pocket for probably many months until either Crypti prices and/or transaction volumes ramp up VERY significantly.

<Insert typical MalReynolds rant blah blah blah>

Mal, you did not consider the Delegate Reward Program in your calculations.  We cannot promise $10 a month in earnings, but the DRP will mitigate the expense of paying to have a running delegate on a cloud server.  I will be running mine on a miner that is on all the time anyway.
You might do the same.

There is no limit to the number of delegates a person can run on the same IP.  The electrical cost of an "always on" laptop with 1 delegate is the same as the same laptop with 5 or more delegates.  

It's on your hard drive or SSD of course. It's theoretically possible, but why should the community vote for two delegates on one node? They will probably vote for another one.

And one could also say this is whats wrong with the current system. People don't want to be held responsible for careless actions. Your right a credit card company refunds you, but if you think thats where it ends your mistaken. We all pay for this with High fees, and Higher prices at the stores. The think that Crypto solves it taking out singel points of failure. Meaning you hold your own Key to your funds, and if some one breaches this only your account is affected, However if Target is hacked then 100k accounts are affected. Do we have every detail ironed out in Crypto yet? No but we are getting better and better every day.

There is a link to the WIki on the OP.  Please go there for all links for Crypti.  We have been keeping it updated.

There is a full explanation by GreXX a few pages back.  But to summarize........... THIS IS NOT NXT OR NODE !!!!

WIth XCR, Crypti, you can forge with 0 XCR in your node, as long as your delegate has enough votes to be in the top 101 delegates.

To forge XCR, you make a node/wallet and have 10,000 XCR in it.  You pay the 10K XCR for forming a delegate, which is just the forging part of your node.  After that, you do not need to have any other XCR, unless you want to vote.  The 10K XCR delegate fee is paid 90% to the other delegates that are forging, and 10% goes to the Foundation for the Node Reward Program and the Faucet.  

You can vote for your own delegate, and other delegates, or just convince other nodes to vote for you.

Votes are cast by the nodes (wallets), and count 1 per XCR in that wallet. A node with 500,000 XCR has 500,000 votes per delegate.

To vote,  that node needs to pay 1 XCR, and then can cast its 500,000 votes for 33 delegates. Thats 500,000 each, not 500,000/33.

The node may vote again by paying another 1 XCR, during which vote process, the node may remove votes from nodes it voted for previously, and add votes to other nodes.  Total votes, up or down, cannot total more than 33.  

The node can vote for max 101 delegates, which will take 4 vote cycles.

The delegates are ranked by total votes... #1 to #101 and then all other delegates are listed as reserve delegates, and advance to active forging only if there is a vacancy in the top 101.  

A cycle of forging is 101 blocks forged.  This starts off with the delegates being chosen in random order to forge a block, one every 10 seconds.  When all 101 blocks have been forged, the cycle ends.  The fees are totaled and paid EQUALLY to all forging nodes.  Delegate #1 earns the same fee as Delegate #101.  

There is no advantage to having massive amounts of XCR, other than the money you will make as the price of XCR climbs.

Then a new cycle of 101 blocks to be forged is begun, and the delegates are chosen in random order to forge.  If a delegate s unable to forge a block, the block is sent to the next delegate for forging.  Every cycle will have 101 blocks forged, even if several delegates drop out before forging that cycle.  Only delegates that actually forged a block will share the fees at the end of the cycle.
