From the whitepaper:


This implies to me that the system is structured with heterogeneous nodes and I'd like to understand better how a node gets assigned the role of "server" vs. "client".

This is an interesting project that could be useful if done properly.

Has the team published any drafts of what the data sharing formats might look like? Have you looked at e.g. the dat project? They’ve done some interesting work in creating formats for data interoperability.

What's the plan for adding new tokens?

In section 2.3.2 of the whitepaper it says:

"In Ethereum, a smart contract can dynamically call any other smart contract, given an address passed at run-time. In contrast, NEO enforces that all calls between smart contracts must be declared statically in advance. This constraint makes it much easier for NEO to implement sharding optimizations across VM state, but means that NEX smart contracts must hard-code all token pairs that are supported by the exchange."

Does this mean that:

1. The UI will have to somehow "select" the newest version of the NEX smart contract whenever a token is added? (Sort of like Etherdelta does with upgrades) and

2. Since the token pairs have to be compiled in, a new token has to be given permission by the NEX team in order to appear on the exchange?

After reading the whitepaper, I'm not clear on how the Indexer is materially different from an order book.

The whitepaper opens by criticizing decentralized order books by saying that:

• There is an execution cost for managing the order book
• The order books are public
• The order books can suffer from front-running
• The order books can be unfair because of latency

It seems to me that, in the common case where parties are publicly advertising their intent to trade with any party, posting to an Indexers is essentially the same as an order book on the above points:

• There's a cost to running an Indexer. How are the fees paid for to incentivize off-chain indexers in Airswap?
• The indexer is public, which is often what you want because you want to buy or sell with anyone, given a price
• You can front-run the indexer when you're not trying to trade with a specific party
• Someone with lower latency can read the Indexer faster than someone with a slower connection.

So I feel like I'm missing something here, particularly around how one pays the Indexers. In 0x, they have Relayer fees. How does that work in Airswap?

Sorry to hear about the hack, Greg! Are there any details about the attack vector was?
