I think the terms need to be a bit more relate-able for most people to understand. Like the voting and lottery, happens automatically and is known as the process of mining and miners. You mention miners once or so at the end but talk about the process of it from the halfway point to the end. Also, I think for the most part, it needs to be noted that this entire process happens automatically behind the scenes. The way you explain it almost sounds like a lot of it has to be done manually on a PC by the users. For example when u first the validation / voting process, it sounds like in order for a users transaction to be accepted into a block, that user would have to generate the block ; another manual implication.

I'm a software dev with 3 decades of experience, but still struggle comprehending all of the bitcoin ecosystem. The 22 minute "How bitcoin Mining Works" helps greatly, but it would help to see an explanation (i.e. historical analysis) of the first 10 or 20 transactions starting at block 0. The genesis block started with 50 BTC, so how did that get spent, when was the first block created, how many transactions did it have, how did new BTC produced by the miners get spent into the transaction chain etc. I'm thinking if I saw how the 3 purposes of mining were fulfilled thru the actual early transactions it would "click" for me and all the pieces would lock into coherent understanding.

@techgarage3720 9 жыл бұрын

By "spent into the transaction chain" I mean where did the coins produced from the first block that was mined go? I envision a tree diagram where the original coins from the genesis block (they weren't mined but were just created out of thin air to reside in the genesis blk; they might be referred to as "premined coins) were transferred (i.e. spent) to an address. Then a miner verified the source (gen. blk) and created the first blk that included that transaction.

At 1:40 you mention the primate key is used with transaction information to create a signature. My understanding of public/private key is you cipher data with the public key that is shared with anybody then you decipher with your private key. So how something cipher with a private key can be read with a public key?

I didn't feel like you explained the double spending prevention and how it translates to the block-chain. How does the "lottery" determine which transaction is legitimate? The way it's explained above implies that both transactions would enter the pool and whichever hash match occurs first gets added to the end of the chain. It obviously can't work this way. Thanks for the video! Lots of good information here.

+David Detweiler Coders mathematicians and economists are not the ones you want to try a ponzi scheme on. Bitcoin works and is open source. I have complete knowledge of how it works because I can read the code. I don't trust a third party about how it works, I can just see it. Like a mathematical proof. I'm not worried Pythagoras is going to change the length of the hypotenuse and make the roof fall on my head. The same way I know bitcoin is not a scam. There is a ton of info online even for non-geeks.

Questions: 1. What happens when people stop mining in 2140 and the math is no longer being done? 2. What happens when the block chain gets so huge that it takes hours and hours to download?

@CuriousInventor 9 жыл бұрын

1. Fees will gradually take over as the main compensation for mining / maintaining the ledger. 2. Eventually only professional nodes will handle the full blockchain. There's no need to manage the ledger just to send and receive money. And every detail doesn't need to be stored, just a compressed footprint. The original satoshi paper discusses this if you'd like more detail.

@unsignedmusic 9 жыл бұрын

CuriousInventor The whole point of BitCoin is that it has no fees. If you use "professional modes" won't that defeat the purpose of not having a central computer?

@CuriousInventor 9 жыл бұрын

***** It's still decentralized, as anyone can become one of these nodes, just not every single user. The developers actually stripped out the ability to easily turn on mining from the base Wallet software back in 2011: bitcointalk.org/index.php?topic=5353.0 And with the advent of asics (special type of chip that mines faster than CPUs or GPUs found in typical computers), there's little point in attempting to mine unless you buy specialized hardware. There's some interesting stuff about fees eventually getting too small to incentivize miners: en.bitcoin.it/wiki/Tragedy_of_the_Commons It seems there's a link between fees and the security of the system, which may be impact the fee levels.

So basically it’s momentous % increase in value is just 1 big pump! There is no way a system like this should increase in value any faster than standard currency long term. Any advantages it has in saving on fees is negligible compared to the cost of all the mining and processing surely, so why the sudden spike in value?
