How are the trades ordered before the ledger closes?



Looking from a "high frequency trading" perspective, is it possible to execute some attacks like front running on Stellar? If my node receives a trade, can I outrun it by submitting my trade faster to other nodes?




ledger nodes dex trade

          I asked the same question earlier.



          Jed mentioned that trades are applied in random (actually, pseudo-random) order, and transaction fees do not affect the order in which transactions are applied within the ledger. So larger fees do not prioritize trading operations, preventing Low Latency HFT manipulations.

            If the validators know how to calculate this randomness, I should be able to do the same. In this case I can just generate a bunch of transactions until the final pseudo-random state suites me. I will read a bit through the stellar-core code just to try to understand it completely.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
