1  Bitcoin / Development & Technical Discussion / Re: Flaws in LN (Lightning Network). on: October 23, 2018, 06:08:51 PM
The LN was tried with a purposeful DDOS exertion, which caused the loss of 20% of hubs. Be that as it may, an ongoing analysis likewise noted different imperfections in the system, beginning with the way that the whole number of hubs is little contrasted with the Bitcoin Core system of hubs. The biggest number of LN hubs stretched around 1,000. In the meantime, Bitcoin Core hubs have developed in the previous months, to 9,277, from around 7,000 amid the season of the SegWit2X discusses.

Also, even with a developing number of hubs, the wasteful channels between them imply that the Lightning Network is fairly disarranged and eccentric in taking care of exchanges. The central issue is finding a reasonable course between beneficiaries, notwithstanding the little broad limit of the network. Indeed, even with in excess of 1,100 hubs detailed, the network does not deal with exchanges above $35, and the general every day stack is worth around $50,000.
2  Bitcoin / Development & Technical Discussion / Re: Bitcoin issued per year formula on: October 23, 2018, 05:39:27 PM
If Bitcoin delivered 50 coins every 10 minutes (600 seconds) the first year, then it should have delivered 50 x (1577000/10) = 7885000 Bitcoin the first year.

But I cannot see this number in any charts like in this one for example where it is said that the first years were added 2625000 bitcoins.

https://en.bitcoin.it/wiki/Controlled_supply

So what is the exact formulas to determine how many bitcoins are issued / year (before halfing)


To calculate theoretically how many bitcoins are mined in one year (assuming 50 BTC per block):

Code:
min/year = 365.25 days/year * 24 hr/day * 60 min/hr = 525960 min/year

blocks/year (average) = (525960 min/year) / (10 min/block) = 52596 blocks/year

bitcoin/year (1 full year, 50 BTC per block) = 52596 blocks * 50BTC/block = 2629800 BTC/year

Note: This is assuming 10 minutes per block, which is just an average. Also, the first block was mined on Jan 3, 2009 and did not continue every 10 minutes at the beginning, it took a couple weeks to begin to stabilize around 10 minutes:



Maybe someone can comment as to why the wiki has 2625000 BTC as the estimate per year, I'm not sure why.

However, The estimation for a blocks in a year in Bitcoin is 210000/4, where 210000 is the subsidy halving height (just short of 4 years). At 50 BTC per block this is 2625000.


Merit will be highly appreciated if the posts seems helpful.
3  Bitcoin / Development & Technical Discussion / Re: Entropy, how to calculate it from series of outcome on: October 22, 2018, 11:23:54 AM
Hello,

I want to generate my own private key with dice and/or other very entropic phenomenon. But how can I calculate if my data have a good entropy ? I mean if I throw dice in a certain way too much time maybe my outcome will not be trully random, maybe my dice is not a very good dice and have imperfection etc.

So can I just throw it 300+ and if I don't have 0.166666% each result (1,2,3,4,5,6) it's not good ?

Also I want to write my own series of dice result just to compare how deficient is my brain when I try to generate true randomness.

Thanks

Try using the an open source program called ent. Here are the results for rolling a die six times with the result vector of <666666>.

% echo -n "666666" | ./ent

Entropy = 0.000000 bits per byte.

Optimum compression would reduce the size of this 6 byte file by 100 percent.

Chi square distribution for 6 samples is 1530.00, and randomly would exceed this value less than 0.01 percent of the times.

Arithmetic mean value of data bytes is 54.0000 (127.5 = random). Monte Carlo value for Pi is 4.000000000 (error 27.32 percent). Serial correlation coefficient is undefined (all values equal!).

"You can lead a horse to water, but you can't make it drink"

If Satoshi had stopped to explain to every single person who didn't get it, they never would have got anything done.  Sometimes you just have to get on with it and allow for other people to get there on their own.  The opportunity is there, but if people choose not to take it, that's up to them.

Agreed with you. Basically, people are confused about the technology and I believe that blockchain is not so easy to understand and therefore fear rise on their mind. But understanding and believing the term who have accept cryptos, are going higher and higher. But i believe that faith on crypto is must to be gainer in this market.

Being a newbie, have got to know a lot about th forum. Since I am planning to do something better in crypto world, I will try to share my knowledge and gather knowledge from seniors. But I am interested to know more on merits. How my posts would be checked whether it deserve merit or not? Any experts comments plsss..

Whenever you post, your post will be visible to other members. If these members find that your post is constructive, helpful etc. they'll merit you. as simple as that.

I agreed and understand that. But I am thinking that if the post is not visible to merit sender on time!
However, I will keep doing my task.  Smiley

7  Bitcoin / Bitcoin Discussion / Thought of Satoshi Nakamoto- Agreed?? on: October 22, 2018, 07:44:10 AM
"If you don’t believe it or don’t get it, I don’t have the time to try to convince you, sorry." -Satoshi Nakamoto

Satoshi Nakamoto was on a mission. He made this very clear with his direct messages on this forum, always straight to the point in order to not waste time that he could spend improving the Bitcoin code. This quote is from a message Satoshi sent to the now founder of Bitshares in response to a comment on Bitcoin scalability.

I am agreed and convinced with the thought of Mr. Satoshi since I have done a lot of study on his this project. Just out of curiosity want to know your thought regarding his this quote.

Thanks for your time.
