Concerns and issue; compiled from a discussion with JL.

The team around AT needs to answer these questions during the testing period of AT.



0) Problem is not to achieve something with AT, but how to restrict AT scripts to avoid inconsistent results: cf. below


1) We need to make it safe in certain ways:
 - restricting AT scripts - transactions validation?
 - can a script create other scripts (viruses)?
 - access on core resources - querying them
 - using core capabilities - like methods of the Account class and so on

2) Scalability:
 - re-executing the script on every node?
 - better of avoiding it?
 - some sort of easy proof that the script was executed correctly?

3) Code complication
 - minimizing the core code
 - if script is using internal core methods, core modifications will be necessary everywhere -> first step: using regular transactions, second step: creating custom transactions, third step: introducing custom objects

4) How to start a script?
 - by transaction?
 - by height trigger?
 - by what else?

5) Scientific research done?

6) How to do debugging?
 - Who called what when and why?
 - different languages in use

7) How to do updating a AT script?

How to migrate running/active AT scripts once the underlying program found flawed and a new version is/will be deployed?

9) Atomicity
 - Are scripts atomic?
 - How to achieve atomicity?
 - How to split up atomicity within one script?
 - When is the output of a script accepted, i.e. changes balances and the like? (turing complete -> Halting problem etc.)
 - rollback necessary?

10) What is the output of a script?
 - a sequence of regular Nxt transactions?
 - using custom transaction types?
 - directly manipulating the Core Objects like Account, Aliases, Orders etc. etc.

11) What is the input of a script?
 - block headers?
 - confirmed transactions?
 - raw transactions?

12) When calling internal methods like DigitalGoodsStore.deliver(), how to we enforce rules that are set by the corresponding transaction type?


That is it for now. Keep you updated.

Is this a good idea or not?

It would be more user friendly to have "remember secret  phrase for this session" checked by default on login so the users won't have to enter the secret phrase sending a message/bid  each time.

If that isn't secure, maybe there could be a 4 to 6 digit pin number that the user could use instead of entering the whole password again.  The app should disable the pin number and require full password after 5 unsuccessful pin numbers are used.  

So the login screen would look like this:

"Remember password during this session" checked by default
Under it, a text field that would say "pin number for the session" (only 4 to 6 numbers allowed)

Nice Idea, Just keep it up.

I will in fact revise this idea

Remove  "Remember password during this session" totally

and just have   "pin number for the session" (only 4 to 6 numbers allowed)

I'd prefer the opposite. Don't input the password on the login screen at all. Input the account number instead. You shouldn't need the password just to look at the state of your account, because the information is publicly available on the block-chain. Further, the login screen should strongly encourage the account number use RS format. That would eliminate problems with people mistyping and opening the wrong account without realising, and then panicking because they don't realise they've done.

The only time you should need your password is when creating a transaction. At which point the client already knows the account number, so it can verify they match and explain exactly what has happened if they don't. If you must, at this point have the option to remember the password for the session.

Ideally the login screen would remember the last used account number, so you wouldn't actually have to type it. Better still, remember the last few accounts and let the user pick one from a list. Better still, have the screen show useful summary information about the known accounts right from the start: individual balances, plus total balance for all accounts, etc. Most people have more than one Nxt account so multiple accounts ought to be easier to manage.

I'm not keen on having another PIN. I already have to keep track of the account number and password; I don't need yet another identifier to remember. 4-6 digits is no easier to copy & paste than 50.

Buff!! This Automatec Transaction thing is way complicated...

Is there a simple explanation for the coding-average-joe?

This is a very good idea. I routinely type random stuff just to get to the UI, and when I want my own account data it's simpler and more secure to check nxtreporting.
It would be great just to type (or select) my address and see my account information. It's enough to provide the passhpase when needed for a transaction, or start forging.
An indicator that shows if an account forges or not would be great. (But I don't think API supports this) If the account not forging the client can ask to log in.

It is Ethereum for Nxt.

I'm ready to implement the next step to Transparent Forging. Usually I do it silently but this time its consequences will be noticeable, so I'd like to hear feedback of the community.

What I'm planning to do:
1. Disable retargetting (the base target will be set to 100%)
2. Enable Time Warp effect (the first forger in the queue will be allowed to generate the block in 60 seconds, next one - in 75 sec, then 90 sec and so on adding 15 sec every time)
3. Enable penalty (an account that skipped its turn to forge a block will be put out of business for the next 1440 blocks)
4. Enable normalization of forging power (difficulty of blocks will be multiplied by 1'000'000'000/X, where X is total forging power of the system)

#1 is an atavism, we don't really need it if #2 is active.
#2 is for convenience, why should we wait 10-30 minutes if the next forger is already known.
#3 is to incentivize forging, it's also a part of 90% protection.
#4 is necessary for security, coz #3 may "disable" some active forgers.

I'm getting a "New Beta" notification in my NXT client. If I update, will that give me access to MGW to test?
Mostly I'd like to see the look and feel of it to put together a film script.

It should be NRS1.2.0e with DGS ... on testnet.

If there an option to see the accounts in numerical format?

BTW, amazing work! Thanks!

Awesome Nxt branded Raspberry Pi Forging Rig anyone?   It will make ordinary cheap forging super cheap. Banana PI and Cubietrucks are being considered too, this will be futureproofed when there are large amount of transactions to be processed.

No more BTC but want more Nxt? Then just mine it at Nxt's Multipool Hashrate.org

Mine with:

Scrypt
Scrypt-N
X11
SHA
Keccak

Some speculation...

What are peoples thoughts on how Nxt will react/not react in the event of a parabolic move from Bitcoin ? I have read the ongoing debate about
if nxt acts as if it is "pegged" to btc.  

Do you think that if Bitcoin goes x 10 , that Nxt will follow suit?  and if so do you think will happen in sync with BTC or lag behind?

i.e
If BTC goes to $5000 (for a arbitrary and pretty figure) do you think NXT will go to $0.47  and do you think it will do it same day, or weeks later?

Or do you think that if BTC goes on a run, Nxt will drop/stay the same/

OR do you think that if BTC goes on a major rally say up to $5000 which is approx 7.6 times higher than it is today, that the attention and hype, money may then pile into NXT in an even bigger way and we could shoot up towards 1 NXT = 1 $

I get the feeling that NXT is undervalued and therefore has the potential to catch up to its value, and then to run along with BTC for now..
but at the moment I am wondering if the more likely event is that BTC goes on a run first, and then NXT tags/lags along with it to a degree... and then for more investment to push up the NXT market cap after it has held onto BTC's coat tails.

If BTC reaches 65 Billion dollar market cap, is it unrealistic to expect NXT to reach a 5 billion marketcap? and do you think NXT would be undervalued or overvalued at that point?  or do you think that at this stage in the networks life there is not the value in the network at this stage to support a marketcap that high?

Also what are peoples thoughts on the NXT "price stability" that stays stable when Bitcoin goes down? do you think that there is some manipulation at play to keep the price stable?

Finally what are peoples thoughts on the NXT BTC "peg"  do you see us moving away from this peg (if you belive there is one) as more fiat gateways
are added? and how do you think this will happen/over what timescale?

If you are in the I think NXT will lag behind BTC with a time delay, and are expecting a rally in btc,  are you tempted to sell your NXT and buy back in later once BTC has rallied?  if not why not..

OR are you not expecting a rally in BTC anytime soon? but expecting on in NXT

Just chewing the cud really....  I am interested in how other people think about it, please share your thoughts/comment on the above.

thanks : )
