Our Binance clone script works in two different types. In addition to Riot’s self-mining operations, Riot currently hosts Bitcoin mining operations for two institutional clients who, utilize up to 200 MW of aggregate power capacity. So, other than most opcodes that read an element from the stack, these two leave the element that they read on the stack. So if that were the last element on the stack, it would actually indicate that the transaction validation has failed. DROP to remove the stack element in order to not fail the transaction validation. Whereas for most CSVs, it would leave an element on the stack that is greater than 0, and that is a truthy outcome and would allow the transaction to pass validation. 1ADD, which turns it into a truthy value. Mark Erhardt: Yeah, I was also surprised on how much Andrew had to write about that, but yeah, it turns out that humans are not computers, and while computers are good at some things, they are not great at other things, and while humans are good at some things, they’re not very good at calculating hashes and doing elliptic curve math on paper.

So, it turns out that we have constants for some numbers in Bitcoin script, and there are single-byte opcodes that can express these constants. The Library of Congress reports that, as of November 2021, nine countries have fully banned bitcoin use, and a further forty-two have implicitly banned it. By the end of the year 2021, bitcoin miners will have "completely" taken over the more distant regions of Kazakhstan. Murch, I’m sure you have something to add here, but is that the gist of it? The 'B-Reg' held the next instruction; by storing it immediately after taking the branch that 'calls' the subroutine, as shown here, the branch at the end of the subroutine is effectively converted into a Return-From-Subroutine instruction. " And I think it’s important to understand here that since both the CSV timelock opcode and BIP125 RBF use the nSequence field for their enforcement, and also due to the potential range values for CSV overlapping with RBF’s range of potential values, it can end up forcing a spending transaction to signal RBF in order to spend a CSV locked output.

So, having an output that includes the 0 CSV forces replaceability. CSV force the spending transaction to signal BIP125 replaceability? CSV makes you set an nSequence value that essentially forces the transaction to be considered replaceable. One cannot trace your wallet address or personal details, but the information regarding how much money was in the wallet during a transaction can be predicted. Mike Schmidt: Okay, Murch, so 1,500 hours is too much for you, but Poelstra mentioned in his answer, "If we could reduce this to one month, 160 hours of work, I think this would be a reasonable thing to do for Visit www.binance.com a certain kind of super-paranoid Bitcoin user who only transacted every several years". " And Andrew Poelstra answered this, providing some background, some other hand-calculation verification techniques that he’s used previously, including Codex32, and he estimates that it would take, even using some tricks and some helper lookup tables, that it would take about 1,500 hours to do that, 36 weeks of a full-time job, even using some of those tricks that he outlined in his answer. It was pretty wild to me how much it seemed like Poelstra had thought about this, and it almost seemed like he was waiting for someone to ask this question on the Stack Exchange to be able to give such a comprehensive answer!

This means data access is much slower as the actuator arm must move more than necessary to access data on the various parts of the disk, files are stored in a non-sequential manner. Mark Erhardt: I would say that working with the people at BitGo for a few years has made me way more paranoid, and I don’t think that anytime soon I’m going to be nearly as paranoid to want to do this. Like, people might not want to just replace the current types of channels with a penalty-list channel. People can use Data Recovery Software that has the ability to extract and recreate the deleted data. Maybe you can explain why. So, yeah, it’s just because we can express the number 0 through 16 with a single byte, and that’s why we have 17 native segwit versions defined in, I think it’s BIP141, yeah. We have five questions that we covered this week. We have Stack Exchange questions we’re going to go through. And, Murch, you asked and answered this question, and in your question you noted that usually decisions, like determining the ranges of values for something, involves binary powers of 2, which would point to something like 16 segwit versions or 32 segwit versions, but we have 17 segwit versions.
