But how does bitcoin actually work?

[@3blue1brown]

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.

6:20 it's not that huge a number giving current computing power. Not to mention there is no global standard any of this is based on. As soon as 256 bit hash collisions come into the public view like it did for SHA-1 just a few years ago the ledger will start suffering from fake transactions. Then you might as well hire people to watch these transactions manually. Maybe get some type of insurance on losses. Then maybe realize that all vulneribilities from the hardware layer to the software layer means you can lose all your money so setup a system to ensure the key exchange is secure, like a network of quantum key exchanges. After all this maybe BitCoin and the like can be safer, you know... *like a bank.*

[@EebstertheGreat]

@@vishank7 All of the work is "wasted" in the sense that it doesn't actually do anything useful. Its only purpose is to make it cost time and money to make a new block. As more people start mining, each block requires more effort to mine and gives less reward. It is a lot like gold mining in that way. If you are mining gold, all the digging you do that doesn't lead to finding any new gold is wasted. But usually there is no way to find gold without wasting a lot of time on misses. The more people mine, the deeper you have to go to find new gold, and the less you usually find. The difference between bitcoin mining and gold mining is that gold has some real utility outside of its value as currency, while bitcoins have no other utility. However, most gold ends up locked away in vaults anyway, so I think it's a reasonably good analogy.

[@mikemian]

To verify requires almost no work, that is to read the block chain to find the transaction. Work is required to validate the transaction, that is to write it to the blockchain. A transaction will typically be written to the blockchain with thousands of others.

The spreadsheet should have a formula to check for re-use of IDs, marking transactions invalid. - if you cannot verify it, you can submit a new entry describing the situation, with plaintext obscenities instead of encrypted message

[@TheGoodGuys_gg]

@Kapin Maintaining a ledger is actually easier in real life. The only reason this comes across as complex is due to the cryptography involved to prevent people from cheating by fabricating data. How do people think banks balance out at the end of the day? A bank has a ledger (balance sheet) of all money incoming and outgoing. Other banks have ledgers too of all money incoming and outgoing, which some of the transactions will cross over to another bank's ledger due to their interaction. If a bank conducts an audit, its ledger should balance out. Scenario 1: If the ledger doesn't balance out, that means there was an error input by an employee or money was lost/stolen. At that point, the bank must tally everything. If any physical money was involved from the vault, the vault must be recounted. If the ledger is still short, they'll start the whole process all over again and recount. Eventually an investigation is opened to find out what happened to the money. Scenario 2: If the ledger does balance out, that means there were no errors and all monetary transactions were accounted for. What if a ledger balances out, but only because an employee stole $100 from a vault and wrote down that the $100 was accounted for? This malicious activity can't be hidden for very long because eventually that employee will have to transfer the contents of a vault over to a new owner and it will turn up short, revealing that $100 went missing under the employee's watch. Scenario 3: An entire bank is corrupt, constantly forging ledgers and fabricating financial documentation in order to get everything to balance out after pocketing the stolen money. This malicious activity can't be hidden for very long because any banks perceived to be involved in malicious activities can be audited by an independent third party and occasionally are subject to an independent audit by a third party regardless of whether or not they were suspected of malicious activities. Prior to centralized banking through the creation of the Federal Reserve, individuals bank themselves audited one another. Discrepancies between each bank's ledger through cross-examination, and any discrepancy between an individual bank's ledger and financial documentation(s) identified cheaters. Because of decentralized banking, banks could police each other to prevent cheaters. Post decentralized banking, the entity that audits and polices each bank is the Federal Reserve, which also handles the production of money in the United States. The U.S. treasury is supposed to handle the production of U.S. currency, but what happens instead is the Federal Reserve loans money to the U.S. Treasury who then prints physical U.S. currency. The U.S. Treasury pays back that loan (plus interest) to the Federal Reserve, causing the U.S. Government (or American people) to be placed in perpetual debt. For example, if you start out with 0 dollars and I loan you $1 at 10% interest, you would have to pay me back $1 and 10 cents. However, in order for you to pay back that 10 cents interest, you need me to loan you another $1 at 10% interest, so you again have to pay 10 cents on. The question, since decentralized banking caused banks to police each other by randomly auditing one another and now centralized banking enables the Federal Reserve as the de facto entity to fulfill this role, what entity audits the Federal Reserve to guarantee it doesn't turn corrupt and begin creative accounting? The answer is no one. There is no entity. Now you know why the Federal Reserve, established in 1913, for over 100 years, has never been audited. An audit would unveil all the malicious activities going on in the U.S. banking industry and what's happening with that interest the U.S. Treasury (or American people) are forced to pay. Anyways, the Achilles' Heel for cryptocurrency (something decentralized) other than it being dependent on the Internet (something centralized) is quantum computing. Once developed, a quantum computer would be able to mine any block and would take over the entire blockchain.

[@annabahador9858]

@@greghughes6766 LOL, I see. I would give you 5 brief reasons why crypto is the best investment, why crypto is the future.

[@annabahador9858]

{i} - Incredible returns : Cryptocurrencies have been around for a relatively short time, but so far they can be and have proven to be more profitable than most other investments. They tend to show wide changes in their prices over relatively short periods. {ii} - Simplicity: They are a real sign of the times; both joining and taking part is simple. You do not have to deal with any institutions, sign papers, or visit banks. You simply create an account, get a wallet, and track all your assets with no effort at all. {iii} - Your money is yours alone: With cryptocurrencies, your money is yours only and stays yours forever. You do not rely on financial institutions for holding or transferring it. You do not have to pay their exorbitant fees. In the long run, it can become the basis of a truly open and decentralized economy. By investing now, you can be at the forefront of it all. {iv} - High liquidity: By their very nature, cryptocurrencies have very high liquidity - you can quickly and easily buy and sell them, and the technological organization of trading platforms allows the use of a wide variety of tools and tactics, such as limit-orders (automated buying and selling at a specified price) and algorithm-based trading. {v} - Favorable forecasts: It is a better solution to invest for the long-term - currently, most cryptocurrencies are going through a downward trend, but most forecasts are favorable and show growth within two to five years. And when we say “growth” in relation to cryptocurrencies, it is often explosive.

this was awesome! I was having trouble on understanding the nodes vs. miners as well as the random number / difficulty adjustment but this totally cleared it up!

[@AbodyRulez]

It could be a hideous question but bare with me Since a country like China owns more than 80% of the mining pools out there with a plethora of hashing power, wouldn't that make their chances of creating a forged fork much higher since most of the computational power is kinda controlled by them? Satoshi Nakamoto wrote the following on his published bitcoin paper: "The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power" Also, he said: "The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes." Doesn't that make the largest pool of CPU/GPU power able to forge the chain?

[@matthewtrimby]

Technically yes, if one person/group could control >50% of the computational power in the world dedicated to mining they could start producing fake blocks that would be accepted into the chain. However here's a few of the factors that discourage this behaviour: 1. It would cost a huge amount (powerful computers, electricity etc) to have that kind of computational power 2. There is an incentive (block reward, transaction fee) for nodes adding legitimate blocks to the chain, this is only awarded after the block is confirmed (6 more blocks added to that chain iirc) - so generating blocks is profitable for honest nodes, i.e. less motivation to try and cheat the system 3. The inherent value of bitcoin is based a lot on how much people trust it, if fraudulent transactions became commonplace people would trust it less and therefore the value of bitcoin would plummet - so the malicious nodes could give their owners lots of bitcoin, but it wouldn't be worth anything Essentially, when it comes down to brass tax, if you have access to that much computational power, its more beneficial to you to use it to mine bitcoin honestly.

As a tech person, I think what has been accomplished with crypto is amazing, but as an economist, I see a problem that I never hear discussed in crypto circles. Investments make terrible currency. Our currency value needs to be stable and predictable over the long term. When people trade in Bitcoin, more often then not they aren't looking for a stable form of currency, rather they are looking to buy low and sell high. For myself, I might invest in a little VC of one type or another, but I would never accept payment in VC because, among other things, I couldn't be sure the value wouldn't plummet any time after I was paid. Think of real currencies like a metro pass. Metro passes are the currency of the metro. When I hold a pass the metro is in debt to me. I am owed a ride on a train. The same idea works for theater tickets, arcade tokens, and another token that can be used to purchase something real and tangible. Why would a company redeem these paper and plastic tokens for things of real and tangible value? Societal laws. What about Government fiat? What is it the promise of? The answer is that anyone who wishes to participate in society and reap the benefits of it has to pay taxes of one form or another. Taxes are enforcible by the state and failure to pay them will result in a loss of currency, property or freedom. So it's not what fiat is redeemable for, but what it prevents that gives it value. Since we all find ourselves in a similar situation, we trade in fiat. So again, I ask anyone, what is crypto the promise of? And please, don't tell me "freedom from government oppression" Give me a real tangible answer, because the way I see it, crypto isn't the promise of anything at all. It is the ultimate Ponzi scheme. However it's spread so wide and so far, it may work in perpetuity. There won't be any big crash, rather it will just circulate around creating winners and losers. There are other substantial problems of replacing government fiat with crypto unless people here believe that crypto will always work alongside government currency. Thoughts?
