NXT is the future


View Profile
March 04, 2014, 06:28:44 AM


Basically, ideas what the specific goals of CCT are regarding NXT.

Schedule:
0) new thread for this

1) define an API
 - heavily use case dependent
 - you should contribute what you want to achieve with cross-chain trading
 - price negotiations?

2) design questions
 - I fear we need something like a plugin architecture as transactions of different cryptocurrencies can look completely different
 - re-use of current AE infrastructure?
 - re-use of AT infrastructure?

3) implementation and test

5) deploy


new thread started for this:

Unless the other block chains are getting downloaded and updates locally by miners on BOTH chains, that can neer happen. Just settle for minimal trust of a gateway with 100% transparency of in-out?

Will take me a while to climb up again, But where is a will, there is a way...

CfB
Could you add a "comment" field to      requestType=transferAsset
This would really help track things for the gateway
[i am assuming that after a block confirms that I can trust the values in all the fields]

James




AGREE! A comment field would be of great help, and probably not difficult to implement!





A bit more difficult but immensely valuable is to be able to optionally set the denomination in terms of units of another asset. I know the NXTcore cant handle fractions very well now, but maybe while we are changing API, we can put it in there with the understanding that it wont work until NXTcore supports fractions. I hope it can support fractions for assets too!

The plan is to have bitcoind, dogecoind, etc. all running on the gateway servers and all three (or more) that are involved in the transaction need to generate the exact same rawtransaction, down to every bit, before any withdrawals are approved. In order for this to happen, they have to all be on the same chain, which we presume to be the main chain if they are geographically separate

With all account balances reconciled after every block and all the gateways and however made clients (via nodecoin-qt) will provide near realtime detection of any problems. Trust, but verified many times.

I think if the gateways provide a 1:1 correspondence (publicly visible) of deposits to assets in AE (publicly visible), then we can directly trade any crypto asset against each other. With a small NXT API change to allow denominating trades in terms of a specified asset, people could directly trade AUR/BTC within NXT AE. There wont be any need to do complicated secrect publishing for each transaction. I think most people are trading more than one trade per day, if they are trading. Seems much more convenient to deposit what you want to sell, trade, withdraw what you got. Or you could just leave it in the community gateway multisig accts.

I really think we are a single API change away from being able to trade any crypto to any crypto. Just need to install all the bitcoind forks on the servers. We can have each set of three servers just multisig one bitcoind fork. The cold wallet multisig trustees would only need to run the wallets for the big money crypto, probably bitcoin and maybe a few others.

I think someone suggested earlier to set up an automated TestNXT faucet.


This would really help to distribute testNxt fast......we have to break this bottleneck.

Idea:

After the release of AE. Making a video with a client of ours to demonstrate all features of NXT would be supercool and would attract many many new users.

Video like this; https://www.youtube.com/watch?v=sZRj7bL7ROs

I think the creator of this video should/can make this; https://www.youtube.com/watch?v=_qi5r9kajDI&feature=youtu.be
With the same voice over.

Do you mean it requires a re-write in a more classic peer-reviewed style, or there's something terribly wrong in the contents?

+1

yes please be more specific

Ok. I don't mean to be a jerk, but in general, the whole publication is more of a document advocating NXT and speculating about it's future than a scientific paper. It is full of numbers made out of thin air and false premises. This isn't the proper way to defend the technical merits of a coin.

Some examples:

Section "What is forging?"

Quote
<snip>...the more Nxt you own, the more often you are chosen to protect the network. There are more complexities than this to help protect the network but this is the basic idea.  What this means is that only a few computers at a time are processing transactions and not wasting energy just for the sake of proving they exist.

This doesn't explain what forging really is, other than that "the more NXT you have, you are chosen to protect the network". What does even "protect the network" mean? How are transactions being processed? How is blockchain consensus reached?  In fact, does NXT *have* a blockchain? etc.

Quote
Cubietrucks dual core 1.2 GHz processor can essentially run at 2.4 GHz since splitting the decryptions between cores is easy to do.  So since 2.4 GHz means 2400000000 cycles/second, this means that we値l be able to handle peaks of 2,400,000,000/958,000 = 2,505 verifications per second.  Currently every transaction is signed once and Nxt should be able to handle over 2500 verifications per second.  But even if we start using multi-signatures per transactions to increase security and average 2 signature verifications per transactions, as Bitcoin does, we can handle 1,250 transactions per second.

This paragraph goes from "Curve25519 takes X cycles, a modern CPU has Y cycles, therefore the upper limit of tps of NXT is Z". In reality, this is much more complicated: Current implementation of Curve25519, network bandwidth and latency, block size, pretty much everything should be taken into consideration.

Also, it's full of speculation:

Quote
Granted it値l be a while but assuming we get to the point where we are bigger than Visa, probably having a trillion dollar market cap by that point, we値l need more powerful computers...<snip>...that will probably never be needed because by that point we値l have designed our own machines that do exactly what we need as energy efficiently as possible and be selling hardware that quickly and efficiently does exactly what we need similar to the route Bitcoin has gone by developing ASCIs [sic]"

Next paragraph:

Quote
Using Bitcoin痴 blockchain as the basis for comparison, Bitcoin痴 blockchain is currently just under 14 GB in size ( https://blockchain.info/charts/blocks-size ).  So a 1 TB drive would be able to fit about 70 times the size of the current bitcoin block chain, and especially once block chain trimming is enacted which should allow storing the entire chain even at peaks of 10,000 transaction per second into less than 5GB. This is very easily doable.

What's "very easily doable"? How "10,000 transactions per second" will lead to 5GB blockchain size? This doesn't even make sense.

Quote
What kind of bandwidth will Nxt need? Assuming the average Nxt transaction is a similar size to Bitcoin, it値l be approximately 512 bytes in size

Why should NXT transactions be similarly sized to Bitcoin's? A normal (ordinary payment) transaction size is 128 bytes.

And so on.

from what i read, both chains are isolated from each other

Isolated, but running on the same set of linked gateway servers which authenticate each other
The more I think about it, a semi-decentralized set of gateways provides a better user experience than automated cross chain transactions. Actually, I could write a standalone program that implements automated crosschain transactions that just constructs the appropriate rawtransactions. No NXT needed at all. Not sure if I should implement it,as it only seems useful for settling large transactions between whales.

"Whale A" I will buy 50,000 AUR for 5000 BTC
"Whale B" OK
Each whale sends the magical parts of the secret sharing, one of them cashes their half, the other uses the info to cash in their half.

I just dont see where NXT needs to be involved in that Whale <-> Whale transaction

I guess the one case is if one of the currencies is NXT. But this requires a lot of changes to NXT core to implement the secret sharing, AT interaction with blockchains (via gateway AM's?). Seems like a lot of unnecessary work.

@CfB if you can just add a "comment" field to transfer asset, I can make the gateway matchup cross chain transaction. It will have some fractional asset issues, but I am pretty sure I can make it all work. PLEASE add "comment" argument to transferasset.

James

P.S. I still want the ability to denominate assets in other assets and fractional asset amounts, but I can wait on that. The comment field is most urgent. If you cant do it, I can dig around in the source to see if I can make a mod that supports it

With 0.8.4e, to switch to testnet you need to set in nxt.properties:

nxt.isTestnet=true
nxt.testnetPeers=bug.airdns.org


Awesome. I set up a couple of nodes.
