Why not ICO?
If we do it we can get much fund because we have better product than Waves, EOS and others.

How to detect that?
Look for blocks that contain such a suspicious succession of transactions. Note that the evil witness could exclude the original tx from his own block to make it look less suspicious, because most likely it will be included by the next witness. In conclusion, you should check such suspicious sequences in adjacent blocks as well. If you detect any, count such events for each witness. An evil one should stick out like a sore thumb.

Hmm, I see.
But It's economically rational for witnesses to do several front-runnings less frequently than the count stick out like a sore thumb .
Releasing a tool that shows the analysis result based on good algorithm will make the community safer.

- Then someone put order of "I will buy at least X of asset A with no more than Y of asset B", a node between him and witness (or witness itself) can see the order, and obtain profit margin  about "Y - (best ask in that time)"?


- This feature is not a distinctive feature of Decentralized Exchange, I think all normal trading markets have same feature.


- I understand " front-running will eventually be detected, and the witness could loose his (hopefully profitable) position as a witness.".
If someone do front-running greedy and foolishly, it's easy to detect.
But is there any detail report about this?
How often nodes can front-run without being detected?
How can we detect front-running concretely? What kind of statistical method can we use?

Hi,

I've read that there can be no HFT and front-running in bitshares2.0. (https://bitshares.org/blog/2015/06/08/lessons-learned-from-bitshares-0.x/ )

But I can not understand how bitshares2.0 eliminate front-running.

I think witness can easily front run and get profits without any risk.

Does "defined fee charged by network" prevent it?
If so, is it fair for everyone than allowing front-run?
Can anybody tell me with an example?
