BTW, as it doesn't need to get global state of the tangle for the node, so is the tangle possible for decentralized game?

Some players may not see actions of others in time. Not sure tangle is good for games.

domob published a paper about "Game Channels for Trustless Off-Chain Interactions" the other day, and I think it is also interesting for tangle.

Maybe really stupid question: Jean-Luc posted roadmap for NXT and one of the planned features will be blockchain "pruning" (next year). Could Iota help using checkpoints not only for security, but also for "pruning" blockchain resulting data size decrease of it?

In other words, how close NXT and Iota can cooperate?

They can cooperate on that. Every iota transaction has "attachment" field that can store up to 385.14 bits of data which can be used for checkpointing and other things. One of such thing is the root of a Merkle tree storing a complete snapshot of Nxt ledger at some block height.

Tangle-blockchain interoperability

Iota does not seek to replace the blockchain entirely, it also acts as a supplementation to the current blockchain ecosystem by acting as a oracle for smart contract platforms like Ethereum and Rootstock. Additionally it increases security of blockchains by enabling the ability to include checkpoints for transactions.

999'999'999.999999999 units.

That is a lot of 9's. Any logic behind picking this number? Chinese people believe 9 is the "ever lasting number".

"Iota" is the 9th letter of the Greek alphabet.

I also thought of GUI devs, 1 billion coins would require to extend the field for the amount more, so subtracting the min allowed unit helps a little by saving millions of kilometers of user screen space per year.

hahahaha, good.

Is that because of the network being fractured?

Also, is there a rough estimate of how long a transaction must be in the system to be considered more or less final?

Like in Bitcoin, there is a 3 block confirmation time and a person can be reasonably assured that transaction won't be reversed.

It's because of latency.

Confirmation time depends on TPS rate. Before TPS becomes constant we'll be using checkpoints issued every 5 minutes, so after your transaction gets more than 50% of the votes you can treat it as confirmed.

Looks like a contradiction at the first glance. CfB/iotatoken could you shed more light on the mining/PoW requirement?

Hiring of miners is required when it's a choice between life or death of the network. In this case you have to move away of total decentralization.

The attacker can leave after he received the good and then issue the double spend as said in the Whitepaper. So the merchant will not see anything until the attack succeed ( if it succeed )

Tangle doesn't remove necessity to wait for enough confirmations for on-tangle payments.

If the network is fracture tolerant, than there is a concern that you might be validating a doublespend transaction without realizing it when creating your own transaction. This wouldn't be much of a big deal assuming only a hand full of dinguses trying to doublespend for personal profit, but what if someone(s) tries to exploit this as an attack vector against the network its self with no intention of personally profiting from the actual double-spend.

Assuming that the main part of the network has most of hashing power, only nodes on the separated part will be affected.

a fluid, self-organizing swarmchain?
what are the data storage requirements for each node/device over time?

Lower bound is TOTAL/numberOfDevice, upper bound is TOTAL, the truth is somewhere in between, because redundancy above the lower bound is needed. TOTAL can be pretty little, though, beause majority of the payments will be done off-tangle, I think.

Centralization of control
As history shows, small miners form big groups to reduce variation of the reward. This leads to concentration of power (computational and political) in hands of few pool operators and gives them ability to apply wide spectrum of policies (filtering, postponing) on certain transactions. Although there are no known cases where pool operators abused their power, there have been several instances where the opportunity were present. This possibility in a monetary system powering a multibillion (in USD) industry is completely unacceptable.

So,there will be another TOKEN except Jinn on NXT AE both for Tangle tech？

Could you expand on your question? Not entirely sure what you are asking. JINN tokens are unrelated to IOTAs
