I would not be so nervous about etherdelta, if you would know more about who is participating to ICO. I mean most are interested in project more then speculation

Yes I see that suppose large Hedge Fund invested about 900 ETH in the project.

I think this project is well done

Regarding large data in full sync to be downloaded, which is also related to scalability somehow, is that introducing ZK-SNARKS (Zcash way of cryptography) is also some solution that will be implemented in light Ethereum Wallet client. ZK-SNarks will be introduced in forthcoming fork on 17-th October. As I understand that Non-Interactive Zero-Knowledge (ZK-Snarks is just one of implementation) gives the possibility to download up to eg. 700 MB data and it will be enough to verify whole blockchain, which is now above 300 GB

Maybe someone would be interested in our solution to the problem (there is included code in python):

Hi,
maybe this link would be interested for someone?

https://medium.com/@krzysztofurbanowicz/what-is-the-problem-now-with-scalability-of-ethereum-network-and-how-to-cope-with-it-41168f153775

Here it is described problem with scalability of network and why we need the hardforks in Ethereum? This is of course my understanding of problem.

Do you think the metropolis hardforks will solve the issue?

All the best.

Hi,

we solved it in that way: https://github.com/BBODTradingPlatform/BBOD .

During the ICO, will be exchange on other side. Price fix -7% to ICO price, which is lineary change up in time from 40% discount to 0.

All the best  

Thank you for good answer

Nevertheless it is rather sophisticated smart contract I am rather looking for simple one, if it is possible of course?

All the best

Hi,

How to create a simple crypto exchange in smart contract in Ethereum network? Do you know the examples?

Hi,

I have some problem, how to maintain price of Token and do not allowing it to fail to ground.

When we have large amount of ETH, then it is not the case.

When we do not possess ETH, or do not want to spend much ETH, is the issue.

My simple solution is to make a leverage on the amount of ETH one have. It means we are doing what banks usually are doing in FIAT money. Just one creates instrument and pay for it with ETH. Then one should also create derivatives, like futures, on asset with 10 to 1 leverage. Next future otpions on futures with also leverage. In such case from like 10 ETH, we make around 1000 ETH value assets, which can maintain price of your Token.

How to write it in smart contract?

Such a solution is a standard procedure in FIAT money and it works for sure

Best Regards...

Don't you think that Ethereum founders want to change current Proof-Of-Work (PoW) to mix PoW/PoS (PoS - Proof-Of-Stake), only becuase they have majority in ETH (money) and not majority in mining power?

This means that would like to have control on Ethereum network and seams currently does not have it.

All the best.

Hi,

As I understand uncle reward in Ether mining is like getting silver medal in olimpic games. It is reward given for someone, who is very close, but not first at block finding.

I just think loud, what is it really for? Because statistically on average, each should get reward on the level of his mining power. This is true, of course, if everybody is determined to mine so long to be satisfied the principle of large numbers (when statistical bias is very small).

Could you correct me if I am wrong, that if we reward only the best and many small miners could not even think of solo mining (like on bitcoin) the statistical bias is so large, that the risk is much larger than potential profit. In this case risk is equall:

      Risk = [energy costs] + [mining devices cost] + [statistical bias, that he will close mining never getting any reward]
   
      Profit = [reward from mining block]

As I understand such a statistical bias, especialy for small miners, is very high, so they never even thing of start mining.

This is my understanding that, why gold and silver medal is rewarded (main block reward and uncle also) to encourage small miners to start.

If so, why it is not linearly diminishing rewarding, means 1st - 10 ETH, 2nd - 9 ETH, 3rd - 8 ETH etc.? It was only the problem with coding such more complicated function?

Can one explain in simple words: how it is written in code such an uncle reward in Ethereum? Maybe it is possible to rid of mining farm and everybody would be than mining solo, getting very little portion of being 100-th in block finding?

Wishing all the best
