Transaction

j"1LAnZuoQdcKCkpDBKQMCgziGMoPC4VQUckM§<div class="post">Just to be able to ask "What if ...?" and have all ideas collected in one place.<br/><br/>For example.<br/><br/>It seems, that a generating node does not need to receive all that transactions at all.<br/>The only data it needs is the previous block hash.<br/>Right?<br/><br/>Next.<br/>It is possible to connect to almost every publicly accessible node, right?<br/>We can collect their addresses and establish connections to almost all of them.<br/>And send them all the data we want.<br/>Like fake (or not so) transactions in huge volumes.<br/>What if it is possible to throttle their generating capability by forcing them to receive and verify<br/>very large amounts of (possibly invalid) transactions (or perhaps another trash)?<br/><br/>If that is true, then we can lower the difficulty, right?<br/>Just do this for a long period of time.<br/>When it lowers to an acceptable for our supercomputer (botnet) value,<br/>we may connect it to the network, but not directly.<br/>Connect it via special node, that does forward messages in a special way, to filter the trash data we are still flooding.<br/>So, the supercomputer will receive the blocks and will participate in generation, the others will be flooded and will get<br/>only a small portion of generated BTCs.<br/><br/>Then, if we are not interested in generated BTCs, we may start generating a blockchain fork.<br/>Immediately after the difficulty drops, we start to generate alternative version of blockchain in a isolated environment.<br/>Since difficulty does not change immediately, we can try to outperform the rest of the network, while they are chewing our<br/>trash data. Fast enough we present everybody with the longest chain, but then the difficulty raises back.<br/>By doing this&nbsp; it is possible to wipe our previous spend transactions, if they are made after the blockchain fork.<br/>So, is it possible that we recover them and get back unspent transactions? And spend them again?<br/>How will previous transactions incorporate into the new blockchain if they were "respent" in that manner?<br/><br/>And then it can be repeated.<br/>If I'm wrong, just say: "you are wrong".<br/>But you may also give me a hint why.</div> text/html
