If you want to check it out, I feel compelled to warn you that it's not the most well-documented tool, and has many other quirks you might expect in a library someone wrote with only their own use in mind.

If you see comments here about investing or brokers, they are scams. Videos about cryptocurrencies, evidently including ones that are just about the underlying technology/math, are hotbeds for attracting nefarious actors preying on the impressionable. Also, hi! If you’re new to this channel, most of it is about visualizing math. I get it, you probably landed here searching for how BTC works, not to spend your afternoon getting pulled into learning about, say, prime numbers or problem-solving, but if you have a moment take a look at the rest of the channel, you may enjoy what you find.

This was the best video I ever saw on Bitcoin, it was so enjoyable I wish there were more like it. Finally, someone answered all the questions that arose in my mind about the private keys and other issues. This was an outstanding video. I'm overjoyed to finally learn more of the nitty-gritty of how it works.

Bitcoin was created by the NSA. It is the onramp to Digital currency. The main idea is to make Crypto so unmanaged by Governments and people that they will have to start implementing regulations to it. That's the role of it. The Digital dollar will replace it in 2022. The US Government bought 200 million bitcoin from 2010- 2012 for $10 each. While owing The American people 3 Trillion they borrowed from Social Security that was due for payment in 2013. What did Obama do to repay our Social Security? he raised the SS tax 2% and didn't pay anything. Since they have 100 million in Bitcoin that is at $50,000 now, so that's about 5 Trillion dollars the Government of the USA has made off of our money. So where is it? This is one of the main reasons the USA wants as many foreigners to come work in the USA and pay into Social Security but are never eligible to receive it. Just as Bush W did to restore SS. If you think no-one has control over Bitcoin, you are deceived.

(CORRECT ME IF IM WRONG) I think I learned something new with that output thing, u can raise how ever many of the numbers available by the amount of positions that number can be in place in -> in order to find out how many different numbers there could potentially be. For instance if there is a 16 number sequence, and in each individual number in the sequence (so there’s 16) it is either 3, 5, 8, or 9 at random. You can say 4^16, which would give me how many potential answers I could have in this sequence. Right? (Btw I rlly should do my math hw and study for my psychology test tomorrow)

@Sagar Nath The ethereum blockchain is around 60KB each, and with all 11.5 million blocks right now you have 690GB of total transactions (not to mention the time it takes as a full node to verify one). In order to spam block rewards you need more hash power than EVERYONE else combined (called a 51% attack), which is very unlikely and has only happened once so far.

The significant difficulties financial backers face may go from controlling lack of caution to the slight of impulse. Most novices and would-be financial backers frequently sabotage and regularly disregard the significance of specialized investigation concerning exchanging. Specialized investigation excessively predicts the development of resource costs paying little mind to what's going on in the more extensive or more extensive market. Basically, the interaction includes contemplating the ways of a specific resource development before to build up a maintainable example that can be utilized to anticipate future developments. I would urge financial backers out there to exchange with the little they have or duplicate exchange alarms from an expert merchant. I have been utilizing Ryan Robert exchanging Signals and Strategy Designer since the last bear market, expanding my portfolio day by day.

Nice and informative video... Well i will also say this here, Bitcoin (BTC/USD) is still pushing higher in a bullish pattern and the leading asset still had more future which a lot of top analyst suggested that it will break the 50,000 resistance zone against the US dollars. Nevertheless it is not wise to keep holding at this point in time, it is best we keep trading by getting involve in day trading and grow the little asset we hold or buy to accumulate more ahead of the bullish predictions. Bitcoin trading has been favourable and profitable because i employed the right strategy/daily signals provided by a Expert trader known as RamAsalya,he is not just a pro but also life savings when it come to bitcoin trading signals and so far have gained so much under his umbrella. În just 5 weeks of activeły trading with his daily signals, i was able to accumulate and grow my portfolio from 1.1btc to a total of 5.89btc which you will agree is a nice one.

Transactions wait in the mempool and can increase fees to get included into a block sooner. Ultimately there is a fee market where low fee transactions get priced out, but they can use a second layer protocol like lightning network to make transactions.

Great video @3Blue1Brown but there is still a level of metaphor that is annoying me and preventing me from understanding. You talk about individual users sending/receiving updated blockchain transactions. Ok, but where is that then stored? Locally? I get the "longest" blockchain transmitted to me via what? Where is it stored? Is that all dependent on some specific application? Does this whole system imply that it would completely cease to function if all the miners and users simply deleted their records and never updated again?
plasticman2011
plasticman2011 Prieš dieną
All network full nodes store the full blockchain on their own computers - stored locally and across the network, but you can run a light client where you only track the transactions you are interested in. All transaction data including blocks are relayed on a peer to peer network. Yes, all data getting deleted would cause the network to stop working, but I'm not sure why people interested in their bitcoin wealth would choose to shoot themselves in the foot like that. It isn't that much data anyway, the blockchain can only grow about 100 gigabytes per year. About half a terrabyte so far in total.
boywisard

Also, if the ledger is the sum of ALL previous transactions, how the heck is it feasible to sustain that going forward? A ledger would be ridiculously huge at some point and you are saying that that is also being transmitted among nodes constantly?!

FACTS ABOUT BITCOIN: It has NO service or product, NO income or asset backing and NO regulation protection. The SOLE OBJECTIVE is to attract evermore new cash from greater fools to drive the price higher so that the earlier punters can cash out with huge profits. Simple, blatant objective. CRIME: and yes, Bitcon is perfect to evade sanctions and taxes, drug payments, terrorism, ransoms and other illegal activities.

Well, I'm not sure if I understand this but it explains a part of the equation, the mining part. But since that depends on speed and computational abilities, that raises questions about who owns better hardware that may not be available to everybody else, who invented the hash functions and simultaneously what if the owners have an agreement to reject or override other's blocks of transactions at will, like if the work has already been meditated since years but not been introduced to the chain yet. Then there's the value that's based on demand and the pubic agreement that a digital asset that serves little or no purpose has a value. To me the whole thing still sounds like a big gamble especially for someone who buys the currency rather than mines it. Thanks for the video 👍

4:37 emmh... no? In fact, every signature is different, even when you need to sign multiple time on the same document (especially that, because you grow tired). Physical signature has always been bullshit.

I first watched this when you released it and since I have come back time and time again to share with others because it's still the most comprehensive explanation of blockchain technology. Even if it has moved on slightly. 👌👏

I was following pretty well until the block creation process. If blocks are chained to other blocks then how can someone just grab a bunch of transactions and build a block? Doesn't the new block need to be chained to prior blocks? If everyone is building blocks at the same time, which block is the last one to chain to? Wouldn't everyone be building different sized blocks of an arbitrary collection of transactions? What makes one chain longer than another if it is only one giant long chain? If chains are not connected to each other (how would that happen?) then couldn't chains contain different collections of blocks? If so, how would I know whether my transaction was included in a block or not? It just seems like a gigantic mess! There must be something missing in Grant's explanation.

What happens if a large portion of miners collude to create a fraudulent block? Would they have to keep it up? would everyone continue to build on top of the fraudulent block?

The fraudulent block is rejecting by the peers who received it, if it is invalid that act as if they didn't receive anything and can even disconnect the miner from their network of neighboors if the miner spams fraudulent blocks. No one else will ever know about the fraudulent block.

A "real US dollar" is a Troy ounce of 99% pure silver. "Real" money is a weight of precious metal. The scum who call themselves "government" hate real money because productive people with real money in their pockets live free of "government" interference, inflation, taxation, auditing, and control.

Here we go: when he starts talking about digital signatures he says “ anyone can get into the ledger and make entries” but then he uses one of the four in his example. So does he mean that anyone within the magic circle can access the ledger or can anyone in the world access it ?

You can maintain the ledger without having bitcoins. The 4 lines which create Ledger Dollars are just for the example between friends. In Bitcoin, you can get tokens if you mine or buy them from someone else.
