2  Bitcoin / Bitcoin Discussion / Largest ever in BTC history. 1.314MB block mined. Segwit is expanding. on: September 09, 2017, 07:41:59 PM
The newly mined segwit block 484398 is largest ever in bitcoin history.  Congrats!

And minutes later, yet another largest block came out lol.  1.372MB!
3  Bitcoin / Bitcoin Discussion / Can we claim that BTC block size is larger than 1MB now? on: September 06, 2017, 08:54:38 PM
In BitMEX (a bitcoin futures market), there is a binary bet.  In the contract, it says
The contracts settle on a > 1MB block being mined and accepted by the majority on the main Bitcoin chain

My question is can we claim that the BTC block size is larger than 1MB now?  Because I look at the blockchain.info, I constantly see block size larger than 1MB being mined.
4  Bitcoin / Bitcoin Discussion / The newly found block has size larger than 1MB? on: August 25, 2017, 07:15:24 AM
woot???!!! Look at the newly found block 481947. It has size larger than 1MB? Is this because of Segwit? Can anyone please explain to me?
5  Bitcoin / Bitcoin Discussion / Segit new block only has 0.3kB size on: August 24, 2017, 03:00:14 AM
what happened to block 481828 ? There is only one transaction. It only has 0.3kB size. what happened with segwit?  Also, shouldn't segwit give more transactions for each block? It looks not from the newly mined blocks. I'm confused.
6  Bitcoin / Bitcoin Discussion / bitcoin cash has zero hashrate? on: August 23, 2017, 05:46:18 PM
Did you notice that in the past few hours, all the hashrate moves away from bitcoin cash to bitcoin? Is this a disaster for bch? nuclear winter is coming?
7  Bitcoin / Bitcoin Discussion / referendum from all bitcoin hodlers on: August 19, 2017, 08:36:08 AM
Would you vote for

1. bitcoin should follow NYA and go to 2MB

or

2. follow bitcoin core and keep it at 1MB


If hard fork happens in November, which one should be called bitcoin?
8  Bitcoin / Bitcoin Discussion / what happened to the mempool today? on: August 12, 2017, 12:46:23 PM
Do you see a abrupt drop of the mempool size today? from 55M bytes all of sudden dropped to 8M bytes. I never any thing like that. what could possibly happened?
9  Bitcoin / Bitcoin Discussion / mempool full and transaction fee rocket high on: August 10, 2017, 10:34:03 PM
What you think of recent sudden increase of bitcoin transactions? I sent a bitcoin transaction 12 hours ago and spent almost 1$ on the fee, it still not confirmed yet.
10  Bitcoin / Bitcoin Discussion / what would happen if one day the hash rate is so high no miner is profitable ? on: August 08, 2017, 09:12:03 AM
The hashrate is increase exponentially and certainly unsustainable. What will happen if one day, the hashrate is so high, no miners would profit from mining it?
11  Alternate cryptocurrencies / Speculation (Altcoins) / How will the creation of BCC affect the function and price of LTC? on: August 03, 2017, 09:58:53 AM
As we know, LTC has some advantages over BTC such as quicker transaction time and less fees. But it seems now the BCC has some of those functions. Does it mean the LTC will no longer as attractive as before and the price will drop? What's your opinion?
12  Alternate cryptocurrencies / Service Discussion (Altcoins) / will I receive BCC from poloniex after Aug. 1? on: July 23, 2017, 08:45:18 PM
I have no way to contact with them. the ticket system is so slow and their twitter account literally publish one sentence a month. They refused to gave users free steller lumens airdrop. Now I don't know if they will give us BCC after Aug. 1.  any ideas?
13  Bitcoin / Bitcoin Discussion / double spending scenario on: July 22, 2017, 05:36:38 PM
Hello, I'm new to this bitcoin technology. And I have a question about double spending. Can you take a look at the following case and tell me what I am wrong

So let's say my wallet has 5 BTC. First I send a payment of 1 BTC to receiver A. It is verified by a full node and put into the mem pool.
Immediately after that, I send all 5 BTC to B. It is then verified by a different full node and also put into the mem pool. Because I put more transaction fees on the second transaction, the second transaction will mostly likely picked up by a miner faster than the 1st transaction and get 1st confirmation. Thus I did my double spending.

Which part of my logic is wrong?

作者简介
嘿,我的名字是Kingn56,自从2012年底以来我一直参与加密货币。作为一个年轻的青少年,当比特币真的开始在这个星球上打响时,我被告知有关比特币,有兴趣购买了一些。多年来在加密货币中造成了很多愚蠢的错误,导致我学习了许多美好的生活课程。在过去的一两年间,我和几位同事一直在质疑我们现在是否是我们发行新币的好时机。现在这个时候来到了!
这个货币与其他币不同的地方是发行量非常少,一共才2500。
