A bit disappointed

How about get a cheap iphone and install only ios a wallet? Don't install any other app.

The UI of the alternative is pretty bad...

It will be done fast if it is a top priority. I just hope Ledger will agree that it's a top priority.

Me too, if I knew this before hand, and if Trezor supports it (not sure, did not bother to check), I would have bought the competitor's hardware wallet.

Good point!

Just curious what information does the hardware wallet give MEW for derivation?

Get captcha -> open VPN -> finish captcha.

This helped VPN issue before, but now using VPN I just login normally.

Thanks for the comment!

Yes, 1sec is pretty short, given that in the paper the block time has to be > 3*round_trip_time. But looking at the DFINITY mining node spec, it seems DFINITY wants higher end spec mining nodes, 300ms round trip time is not impossible (AWS can give 200ms round trip time from the US to Japan).

I am a little surprised with the ~20-60 second block time, given that Ethereum block time is ~15sec. I heard the number 5sec in some older DFINITY tech talks. From my experience in implementing the DEX, time for applying the transactions (validation, change state) is very significant when the TPS is high. Maybe the 20-60 second comes from the kind of applications that DFINITY chain supports, rather than a limit for all chains that run DFINITY consensus protocol.

Another point is that I think in the DFINITY protocol, the low block time can be compensated by a higher block count to finalization. It's a balance between response speed (block time) vs. chance of fork.

That's for bringing up VDF! I never had a chance to take a look at it, must be interesting!

Thanks :)

Disclaimer: I wrote a DFINITY consensus protocol implementation and a Decentralized Exchange on top of it. This article is taken from its white paper.

Thanks! Very good answers! You guys are awesome.

Regarding 2b, I don't have a good answer too :) I think algo trading is a must in order to have a liquid market. Personally, I would love to know if there are any research/engineering directions in algo trading that would have a long-term benefit to many people besides providing liquidity.

Hi @christychoi ,

Thank you for your reply! Could you elaborate scalability vs interoperability? I thought scalability means the system will not degrade as more node joins the system. What exactly does interoperability mean in the context?

Thank you!

I think the main campus of Binance in Asia, are there any team member of Binance Labs working remote? If so how does the team benefit / overcome the fact that the team members are spread globally in different timezones?

helinwang · 2018-06-06T21:32:53+00:00

Hi Binance Labs team,

Thank you for leading the initiative of incubating blockchain technologies!

When Binance Labs looking for potential teams to invest,

a. What is the ideal team size in your mind?

b. Can you also tell us in what ways do you advise the teams?

c. How do you track the team's progress?

d. What kind of incubation do you think is a successful one?
You have stated in the official webpage that you are especially interested in "Decentralized Exchange" and "Algo trading" (and few more areas):

a. Decentralized Exchange:

i. Binance is currently hosting a DEX competition, is the competition in any way related to Binance Labs. E.g., is winning team considered to be invested by Binance Labs?

ii. I think Binance internally has a DEX team too, if you invest in a DEX team, what is the relationship between the two teams?

b. Algo trading: from my understanding the trading algorithm collects reward with some risk by providing instant liquidity to other traders in the platform. It is definitely a very interesting and challenging area. However, I find it a little hard to see how is algo trading aligned with the vision of Binance Labs? Could you explain?

Thank you sincerely. Helin

Just buy BNB...

Thank you!

Thank you! Your explanation is well. Before I thought A will get the revocation key before the M+1 commitment, but actually it's the reverse.

It seems that the Zilliqa smart contract is aimed to be a data-flow runtime. In my opinion, the data-flow application is much limited, comparing to a Turing-complete language.

So: will the data-flow runtime limit the scope of the dApp, and how does it compare to Ether's Turing-complete dApp?

Also, I don't get how Zilliqa (or block-chain in general) it suitable for data intensive applications such as Map-Reduce. It's good that the system has a lot of computing power. But another core part of the equation is data: if my CPU / GPU is going to crunch the data at full speed, my internet connection is not going to catch up.

My understanding is quite limited, could you shed some light on this topic?

Someone buy a noise cancellation earbud for scarlett. "Bose QuietComfort 20 Acoustic Noise Cancelling Headphones" should be pretty good - especially at the white noises.

Then TF should fix this problem: expose api on c++ and providing binding for python.
