NXT :: descendant of Bitcoin - Updated Information

[msin]

Its quiet here, perhaps the calm before the storm. jl777, great job on the zerocoin project, do you think its doable from the code you have?

[Come-from-Beyond]

Anyone can clone Nxt, but CFB can kill it.

CFB won't kill clones.

[Come-from-Beyond]

So, because Utopian is a Nxt support, it's okay for him to create a clone?

It's OK to clone even for u as long as u don't try to scam ppl.

As long as we get several more people to help, we can get a proof of concept NXTcash testnet (Mar?). It won't be usable for end users, but it will show the zerocoin team we are serious. At that point we will either get direct help from them or early releases of their upcoming zerocash as we would be able to help them debug it. Even if we don't we would have shown we can encapsulate C++ and call it from NXT Java code, so as soon as their zerocash is released in May, we can start porting.

At that point, depending on how it tests out, we might even be able to release it, or we might have to refactor it into 100% Java. Not sure on that point.

Still need to solve a few mysteries, too tired now, but maybe somebody else will find an easy solution. Battling with where and how the redeemed NXTcash gets sent. Will it be an asset in Asset Exchange with a decentralized autonomous gateway? Stuff like that. Suggestions welcomed that's for sure as this is pretty cutting edge stuff I don't think many people have much reference to go by, any idea is potentially a good idea.

https://github.com/Zerocoin/libzerocoin/wiki/Integrating-with-bitcoin-clients is the key info on how to integrate zerocoin onto NXT.

The important thing is that NXTcash will be purely optional and if someone does not want to use it, they wont have to. Converting NXT -> NXTcash will be done locally and take about a minute, that is the longest time with the upcoming zerocash release. Also, anybody using NXTcash will need 7gigs on their HDD, so probably will never work so good on smartphones. Current cost will be 2 NXT and maybe a bit more, not sure until we figure out exact redemption control flow.

Feeling a lot more optimistic about this, even without any help from zerocoin team. We just need help from the key NXT peoples!

NXTcash, the next form of cash!!

P.S. Any chance of reserving the NXTcash asset name so all of NXT could use a common sense name for it? Not sure if Asset Names are transferable. does anybody know?

No chance to reserve, but u could offer the highest fee when AE is activated. Asset names r not transferable.

its sort of like the recognition of this problem has caused people to attempt to compensate for it and in so doing they created a situation where its less of a problem in the system where its supposedly a problem than in other systems where its not.

Seems too complicated as we are far from even knowing if we need a robot gateway for this and how will that even be implemented, details, details...

Separately, would it be possible to get an API call that somehow implements:

The client (spender) generates a CoinSpend signature on the transaction that includes the hash of the transaction as well as the Accumulator and PrivateCoin object. The resulting CoinSpend embeds both a coin serial number and a set of zero-knowledge proofs that prove (A) that the spender knows a coin in the transaction set, (B) that the serial number is consistent with the coin, and (C) the spender knows the secret values for the coin. These are all tied to the transaction hash. The client (spender) serializes the CoinSpend object and transmits the completed ZEROCOIN_SPEND transaction to the network.
[from https://github.com/Zerocoin/libzerocoin/wiki/Integrating-with-bitcoin-clients]

The above needs to trigger a NXT payment from some magic acct that previously received NXT. I just can't figure out the logistics of all that.

Any time frame for activation of AE?

Was there a decision on a specific block height yet?

Looks good!

The Transactions Per Second section says Nxt will be able to handle 1000 TPS with Transparent Forging. My understanding is that it won't be limited to this, but may actually support much larger numbers. What is a better way to phrase this? "thousands of transactions per second"?

The section on mixing services could be expanded to include examples that the average citizen would find useful. e.g. "you can prevent your insurance company or employer from snooping on your medical expenses and terminating your contract if they suspect you of being ill, and prevent advertizing companies or neighbors from spying on your spending habits".

Typo in Transparent Forging section: desifgned => designed.

I think it's possible.

Depends on AE client devs, community that will test them and Jean-Luc who will decide what height to add the feature at.

Great! I knew you could solve this. Please let us know when you have any details on this, I will feel much better about zerocoin port knowing the exact mechanism for this. Maybe it has to do with special account 0?

If all the peers can validate all the spends, then I guess all the account balances update properly and no client needs to get password for any special acct?

Feel free to post a specific API call you could implement. That will give client devs a framework to code against.

Thanks!

where it says "nxt uses a simple script for transactions, so they can be secured only by a mobile phone or raspberry pi" It's a bit confusing. Maybe consider changing it to something like "nxt uses a simple script for transactions, so they can even be secured by a mobile phone or raspberry pi"

@CFB A few questions

How exactly is it known who gets the next block? are the coins unique? what exactly makes your account different from another one with the same amount in terms of mining?

Is NXT messaging implemented yet?

Does the open marketplace have an estimated date for when it will be released?

thanks

Why "script"? Nxt uses data-driven approach, not predicate-driven.

I was just pointing out a problem with the semantics. if there is a problem with the content than ill let you deal with that.

Complete iteration thru all account lets to calculate the time when a particular account could forge a block. Coins r not unique. The public key does.

Is NXT messaging implemented yet?

Part of Nxt Messaging is already implemented (Arbitrary Messages, Alias System), part is being implemented (Account Control).

Does the open marketplace have a date for when it will be released?

No. Maybe it won't be implemented at all if someone does it by using Arbitrary Messages and Account Control.

Hey - just a quick holler from me here ( just got up ) - I could be the guy for this, because I live ib Berlin, and I have NXT running on my rapsi since 4 weeks without the solar panels thoug, but still I am familiar with the system!

Let me know some more detail!

[Come-from-Beyond]

There is a problem, it's incorrect to say "script". But salsacz couldn't know that, coz it requires deep knowledge of Nxt internals.

i believe you but additionally there is a problem with the semantics. it doesn't translate the way he thinks it does.
