then if you're not talking about governance, you're still wrong. there's no voting, only if you insist on re-defining what words mean, at which point i won't be interested in continuing the discussion.
The leader can even opt to put no transactions in the current block, something that has actually happened on many occasions: https://www.theblockcrypto.com/post/67928/bitcoin-miners-are.... Obviously, the leader was making a decision here, there were not actually zero transactions to process :)
No, there is no voting and there is no leader election. Miners construct blocks with transactions and if they manage to find a signature - that block is appended to the chain. If somebody does it faster - they append their block.
Please at least get the basics before you start arguing with people.
I know far more about Bitcoin than I ever wanted to, believe me. You really should not be making these kinds of ad hominem arguments when you don't understand terms like "consensus" or "leader election."
No, the hash that you win with, deterministically points to the only possible block that you can “propose”. Your understanding is completely backwards. You seriously don’t know how bitcoin works.
Here is my question to you: if the node that wins the election (and the ones that accept its mined block, of course) is not the one voting on which transactions get to go into the chain, rather than be stuck in the mempool somewhere, who is? Do you genuinely think there is no decision being made there?
All miners “vote” by hashing and one of them wins. They don’t win because somebody voted for them, they win because they happened to find a satisfactory hash. The chance to win that hash faster than other miners is proportional to hashrate. The hash is determined by the block of transactions entirely, so once you win the race, you don’t get to propose anything other than that one predetermined block.
Which transactions go into a block is decided before any mining for that transaction happens.
Just read, please.
You're coming off worse in this argument because you seem to realize on some level they're just using different (possibly wrong) terms in their accurate description of the mechanisms, but then you keep making snide remarks that imply they don't understand the mechanisms.
I think your analogy to flat earth was better. Because sure, treating the earth as flat isn't correct, but it's often a perfectly good approximation, and arguing about whether a big field is flat or not is a giant waste of time. Don't completely dismiss someone because they use those terms.
"Leader" or not, it's basically equivalent. And the process of letting miners input yes/no values for whether they support a proposal into their block, averaged over thousands of blocks, gives you the same result as "voting". So talk about whether those results are useful.
There is no "voting" and no "leader" except in the most abstract sense and I'm not sure why you're so determined to use those terms.
Every 10 minutes a miner wins the right to append a block to the chain, by guessing a secret number. The chances of winning are proportional to the amount of money each miner has expended in the process of guessing the secret number. This is equivalent to holding a vote every 10 minutes in order to choose who gets to append the transaction block. Therefore, you're wrong. There's a vote. And if you can't understand this obvious fact about bitcoin, you have no business discussing bitcoin.
As I said in a sibling thread, it’s like arguing the earth is flat by proposing a very special metric of space. Feel free of course, I just don’t accept it.
Of course, they have a choice. If didn't, miners would serve no purpose. We would just have one block and that would be the block that would be appended. The consensus would be achieved automatically, without any need of guessing secret numbers.
> And if it was an election, wouldn’t the result always be the same with largest miner always winning because they have most votes?
No, because the miner is elected at random. The crucial point to understand is that their chances of getting elected are proportional to the money they spent. That doesn't mean the largest miner will get elected 100% of the time.
lol, no they don't.
a certain hash wins, every ~10 minutes. that hash is calculated from sha(block, nonce), where nonce is the randomized part that miner mutates to get different hashes. once a hash that satisfies the protocol is found - that's it, you can't choose a different block to append to the chain.
it is just laughable that i have to explain this level of basics.
Maybe this article will help you understand just how nonessential the fact that the block is part of the SHA actually is: https://www.usenix.org/system/files/conference/nsdi16/nsdi16.... Please read the whole article, and then come back so we can have a discussion on equal footing.
well certainly not the winner of the "election", because by the time that "election" starts, the block is already constructed.
and i'm not going to read any of your links until you actually start understanding the basics of bitcoin protocol. though your lack of understanding explains perfectly why you fall for scammy bells and whistles of competing bitcoin-wannabes. "bitcoin new generation". lol, give me a break.
Again, I'll ask you, since you keep dodging the question: if the node elected as leader is (according to you) not choosing the block, who is choosing the block? Why are you so obsessed with whether the value was chosen "before" or "after" the election, which is an irrelevant detail of the protocol? If you can't answer these things and won't read the paper, I don't really see any reason to keep talking to you, because all you've done is make the same irrelevant point over and over.
1. once the "leader" is "elected" 2. do they have a choice of what block to append?
you said they do, which is fundamental lack of understanding of how bitcoin works.
> when the leader is elected every 10 minutes, do they get a choice of what block they append to the chain?
and the answer is yes, the miner that gets elected chooses which transactions to append to the chain. Do they pick the transactions after getting elected? No, they pick them before getting elected. In fact, it doesn't matter whether they pick the transactions before or after getting elected, because their chances of getting elected are unaffected by which transactions they picked. Therefore, it makes absolutely no difference. The fact that you think it makes a difference tells me you're very confused about the role miners have in the bitcoin network.
Maybe they act like all the other rational miners and optimize by mining fees.
Maybe they include no transactions and only take the miner reward.
Maybe they they don't like the Dutch so all their transactions are excluded.
It really doesn't matter as all y'all have been arguing over is what to call the person who won the current round.
You really don’t see how this terminology is completely incoherent for this scenario?
This is expanded upon in the peer-reviewed Bitcoin-NG paper that both of you are refusing to read, which breaks down the Bitcoin protocol into distinct parts (which was why I linked it--not because I am proposing that it replace the Bitcoin protocol, but because I thought it would be useful for you to understand how Bitcoin performs leader election already). Specifically, it analyzes the effects of splitting up leader election and block commit parts of the protocol. As it turns out, it has essentially no effect on Bitcoin's security guarantees, which is not surprising--because the fact that block selection and leader election happen at the same time is an implementation detail that doesn't actually matter! Once you realize this detail that you are obsessing over (the block being decided at the same time the leader is) is not important for the protocol, you will also see that the leader election is in fact the critical part.
A miner can choose which block to build on. At any given moment Bitcoin can have several competing "in progress" forks. This is why most exchanges require... 7, I think?... blocks on top of yours to consider the transaction more or less confirmed.
> And if it was an election, wouldn’t the result always be the same with largest miner always winning because they have most votes?
Yes, this is a 51% attack in Bitcoin. If you have a majority of votes, you can disregard the current chain, fork from behind, and catch up.
Yes, they do get to choose the block. Transactions to include in the block are (usually) chosen from the mempool, which is unique per node (it’s similar but never exactly the same between any two nodes). Miners can also choose to include transactions that were never publicly broadcasted, and therefore never appeared in another mempool. Typically the transactions with highest fees are chosen, although fees can also be paid (or bumped) outside the mempool.
The miner of a block doesn’t get to choose the contents of every transaction, but they do choose which transactions to include when they win a block.
It seems like you’re hung up on terms that aren’t commonly used in the context of bitcoin mining, but are valid and are commonly used in the broader context of distributed systems.
