double spend attack: Is this actually true for the more time progress the higher the probability of success for attacker

double spend attack: Is this actually true for the more time progress the higher the probability of success for attacker

I'm new here. I have a question here. Some experts keep saying that this assumption isn't formally correct and I don't really understand why or why they might be wrong.

In the double spend attack; you have attacking network and honest network. Total Hash rate is split between those.

some experts keep saying that time is not a factor in determining how fast you can generate blocks. That's something I don't really get.

So, is it incorrect to say that the probability of success of the attacker increases with the time T it takes to generate z transactions since they have more time to secretly mine their alternate blockchain ?

Recently, there have been frequent cases when these applications stop sending transactions, when restarting, an error occurs: "Corrupted block database detected.

sendrawtransaction and txn-mempool-conflict When i sendrawtransaction to bitcoind, i get error (exceptions) 18: txn-mempool-conflict (use Bitcoin JSON-RPC denpamusic/php-bitcoinrpc ) But the transaction is sent to the network and is subsequently confirmed. Example one decoded transaction : https://jsfiddle.net/rn58a4j6/ then i send this transaction: 94ec12fc463230b4285a29b047608627c05572a4c6eabe6688a201ce49ae72f7 https://ift.tt/2MY2KP0
