Can we change URI afterwards? I have no idea what to put as URI...

Yes, u can. Leave it empty to get the smallest size of the transaction.

Thank you for your continious support here.

No. Peers will reject transactions until they see block 22000. If block 22000 will contain AS-transactions it will be rejected.

BTW, the AS tx will be picked according to fee/size, that means, the network will pick the bigger fee/size if the name is the same, or the network will pick the biggest fee/size among all the names? 

Look forward to how many tx in block 22000, 22001, 22002, ......

the first stress test of the network!

Among all names and a block won't contain 2 identical aliases.

All you would have to do is brute force the creation of a key pair that digested the 1440th genSignature to a hit that was below everyone elses target. It would be totally doable.

This problem is super solvable though. BTNext should make the BaseTarget adjustable with an algo similar to bitcoins re-target algo. Then Increae the 1440 block (24 hours) restriction for effectiveBalance out to about 43200 (1 month) just to be extra super safe (its best to pick absurdly safe parameters when dealing with billions or possibly even trillions of dollars someday). Then finally make the nextGenSignature a digest of the prevGenSignature + the public key of the author of the last block. You couldnt game it with intentionally selected keys because you would have to pick the key 1 month ahead of time and there would be no way to predict who would author which blocks 1 month out since miners drop in and out of the network at random.

1440 blocks is safe number coz u have to know who will sign the 1439th block which depends on the signer of the 1438th block and so forth. To know future signers u must know future balances. Even if u know future balances u must know future topology of the network to predict which blocks will be orphaned.

im so sorry to keep pestering you. but why is this the case. inorder to do this

If you try and buy an alias that has already been bought, do you still pay the fee or is this returned to you?

Also, if you submit a buy order, all you get back is a transaction iD? Does this happen all the time (whether success or not)? Then how afterwards can we check if the alias is ours?

Ok, once an Alias is assigned... will there be an input field for users to type an Alias and, therefore, get redirected or will users
need to type something like https://locahost...etc. to access Alias?

thnx   Smiley

Links on webpages will be altered by a simple JS-script. A plugin is necessary to redirect to correct URI if alias is typed in a browser address field.

What conditions are needed for a person to type nxt:myalias in my chrome browser to go to my preset URI ? plugin for the browser ?  any plan for the plugins yet ?

Internet naming system rebirth. It is going to be huge.

Coz block 1440 winner is determined as Digest(Digest(Digest(...1435times...Digest(Signature_of_block_1)...))).

Returned.

Yes. Yes. http://localhost:7874/nxt?requestType=getAliasURI&alias=Google or http://localhost:7874/nxt?requestType=getAlias&alias=48653875628491834756 where 48653875628491834756 is transaction id of the very 1st assignment.

"nxt:myalias" requires a plugin. Noone is developing it AFAIK. Also u will be able to type "http://anypublicnode.com#myalias" to be redirected to the URI (if it's URL).

Do we have to use https://localhost:7875/alias.html?  Can we use the "assignAlias" API instead?

Yes, we can.

Coz block 1440 winner is determined as Digest(Digest(Digest(...1435times...Digest(Signature_of_block_1)...))).

But that doesnt explain why you would need to know who future signers are. It only says that you would need to calculate the 1440th generationSignature and pre-empt it by creating an account with a key-pair that would cause your hit to be lower than everyone elses targets right? how do future signers effect that situation?

Output of the last digest depends on ur public key and generating signature of previous block. It's deterministic but still can't be guessed. Look at this example:

Alice signs block 1 - signature is A
Bob signs block 2 - signature is Digest(A + Bob_public_key)
Charlie signs block 3 - signature is Digest(Digest(A + Bob_public_key) + Charlie_public_key)

See? U can choose any Charlie_public_key but without knowing Bob_public_key in advance it gives no advantage at all.

yep! i do understand. we just weren't communicating properly. as soon as i thought i saw a problem what you wrote up there is exactly the solution i proposed. Grin bcnext is a freaking genius. I worked so hard to try to figure something out like this myself to no avail. What i proposed in my thread is a far cry from this much better solution.
