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?
2nd transaction will be removed from mem pool. How can the mem pool determine which one to remove? Is there a timestamp? because the first one comes earlier or what reasons? Transactions of double spending (from conformed blocks) never accepted in mem pool, and removed if have. |

No. Do not do that. Please stop spamming that nonsense. Bitcoin Core 0.9.1 will likely not be able to sync with the network anyways. It has known performance and security issues. Furthermore, you will not be fully validating all active network rules. Lie. It best version and working perfect. And the only way to save your coins from "soft fork" attempts. ----- For more information - do read my signature. |

Bitcoin protected by many people: 1. Miners (not only mining pools but miners itself, miner select pool with policy he accept) 2. Exchangers (at now main giver of price to Bitcoin) 3. Mining pools. No one of this people want bad for bitcoin. Do not trust to bitcoin-core developers and use bitcoin-core of 2014 https://github.com/bitcoin/bitcoin/releases/tag/v0.9.1Аnd wait until everything will clears up. ----- For more information - do read my signature. |

How many people are going to take advantage of an event that has little or no effect on anyone? This is a soft Fork not a hard Fork it cannot hurt anybody at cannot split the coin.

OP---> You do realize that the Ethereum Project was an ICO right? The majority of the pre-mine ether went to the pre-sale wallets, so your original premise has lead you down a very slippery slope....However, you have great energy--->keep up your research and your competency will increase along the way. I think you may find that the knowledge and the skills you've acquired over the course of your studies will be very valuable someday.
Can you prove that the buyers of the ICO was real? If not, crowd sale = premine. So they did not made any money with the ICO? is this another FUD? Pajeet make 100,000,000,000 coins Pajeet sell 1 coin for $1 to hes brother Pansun Now we have $100,000,000,000 capitalisation WOW!!! |
