How Does Blockchain Work For Dummies

A Blockchain Explanation Your Parents Could Understand

Solana Explained for Dummies (re-release) Animated Humor

There are two main differences between how Shreks ledger works and how a blockchain works:

  • Blockchains are tamper-evident. Blockchains contain data showing anyone with a copy of the ledger if someone else is trying to tamper or change it.
  • Blockchains are distributed. Instead of having a single trusted third party control it, there are many copies.
  • Lets take these in turn.

    How Mining Works In Blockchain

    It is difficult to fully explain blockchain technology for dummies without understanding mining. Modern blockchains most often use two consensus algorithms, such as Proof of Work and Proof of Stake , and mining is used in the first one.

    In PoS, coins are counted as mined and regularly distributed to participants according to how much cryptocurrency they have in their wallets.

    In PoW, to calculate the hash of the next block, miners must go through billions of numbers one by one and find the minimum value that satisfies the conditions of the problem described in the cryptocurrency protocol. You have to find a solution to the equation, using tremendous computing power, which is capable of quickly going through the options.

    The first miner to find the hash gets the reward. The other nodes can only verify that the hash is correct and confirm that a new block has been added to the blockchain. If the other miners realize that the hash is calculated incorrectly, they will not accept it and add it to the base.

    What Is The Guinness Record For The Most Expensive Pizza

    During the summer of 2010, when many had doubted the concept of Bitcoin, one of the early adopters named Laszlo Henitz tried very hard and succeeded in ordering pizza and paid for it with Bitcoin.

    In those days, Bitcoin was worth nothing , and to order two family pizzas worth $ 30, Laszlo paid 10,000 Bitcoins! What was later considered as the first-ever purchase in Bitcoin, also became the worlds most expensive pizza. 10,000 Bitcoins worth today more than 500 million USD.

    Limitations Of Blockchain Technology

    Blockchain For Dummies

    Now in this beginners Blockchain tutorial, we will learn about limitations of Blockchain technology:

    Higher costs: Nodes seek higher rewards for completing Transactions in a business that work on the principle of Supply and Demand

    Slower transactions: Nodes prioritize transactions with higher rewards, backlogs of transactions build-upSmaller ledger: It is not possible to a full copy of the Blockchain, potentially which can affect immutability, consensus, etc.

    Transaction costs, network speed: The transactions cost of Bitcoin is quite high after being touted as nearly free for the first few years.

    Risk of error: There is always a risk of error, as long as the human factor is involved. In case a blockchain serves as a database, all the incoming data has to be of high quality. However, human involvement can quickly resolve the error.

    Wasteful: Every node that runs the blockchain has to maintain consensus across the blockchain. This offers very low downtime and makes data stored on the blockchain forever unchangeable. However, all this is wasteful because each node repeats a task to reach a consensus.

    The Mining Profitability Of Different Cryptocurrencies

    Some tech junkies mine just for the heck of it, but at the end of the day, most people mine cryptos with profit in mind. But even if you fall in the former group, you may as well get a reward out of your efforts, eh?

    Mining profitability can change drastically based on cryptocurrency value, mining difficulty, electricity rates, and hardware prices at the time youre setting up your mining system. You can go to websites like CoinWarz to see which cryptos are best to mine at a given time. As of September 2018, for example, that site indicates the most profitable cryptocurrency to mine is Verge , while Bitcoin is ranked number seven, as you can see here.

    Even if mining isnt profitable at the moment, your cryptos can be worth a lot in the future if the coin value surges. By mining cryptos that have low profitability at the moment, youre taking an investment risk.

    Why Digital Scarcity Matters

    While blockchain technology is often compared to the internet, the property of digital scarcity makes it fundamentally different. Bitcoins most interesting property is that it allows for the secure ownership and transfer of property rights without relying on a trusted third party or institution.

    When we cant reliably predict the behavior of others, we dont know whether to cooperate for the greater good or act selfishly for our own good.

    This a fundamental problem of civilization. Should you cooperate with someone else to hunt down a stag, or stick to hunting much smaller rabbit which you could hunt alone? The stag would be more food for both of you if you shared it equally, but how can you trust them not to hit you over the head with a club and steal the stag? To scale coordination, we must find a way to solve these dilemmas and cooperate.

    Prior to the Neolithic Revolution, coordination scalability was limited by Dunbars number: As long as you lived in a small band where you had strong social ties with everyone, you could trust them not to screw you over because it would get them kicked out of the tribe, the equivalent of a death sentence.14

    A business requires investment to get started, and it only makes sense to invest that money if you can feel confident that you will be able to maintain ownership and reap the benefits.16

    Blockchains: A History That Is Harder To Manipulate

    What is Blockchain: Guide For Dummies  Ameer Rosic  Medium

    The idea of a digital currency like Bitcoin was around as early as the 1980s. There were companies started in the 1990s and 2000s that tried to create a digital cash system including eCash and Paypal .3

    The key challenge of digital cash is called the double-spending problem. Digital goods can be easily copied which is great for things like email, file sharing, and social media, but a horrible characteristic for money or property.

    You own your car because there is an entry in a ledger somewhere that says its your car. In the U.S., car titles are usually issued and maintained in a ledger by the Secretary of State in the state you purchased the car in. If I could copy that entry and edit it so that my name replace yours, then I would own your car. Same with your home, your bank balance, and your personal data. You only want one, definite copy of that ledger floating around.

    Historically, the only way to solve the double-spending problem was through institutional trust: trusting a third-party institution like a county registrar, bank, or payment processor to not let anyone double-spend.

    Shrek and Donkey could appoint Lord Farquaad to keep the ledger. Sadly, like some people in powerfrom corporate executives to government bureaucratsLord Farquaad has a massive inferiority complex. He isnt that happy about his life, which he compensates for by being a prick and screwing people over at work.

    The Three Pillars Of Blockchain Technology

    Blockchain Technology gained popularity due to the following three excellent features it offers to different industries: decentralization, transparency, and immutability.

    Before the invention of Bitcoin and BitTorrent, we were familiar with only the centralized services. Its as simple as that a central entity will control all the information flow in the network. For getting any information from the particular database, you have to interact with the central entity.

    Our traditional banking systems work in a centralized system. Therefore, we dont have much control over our money because you can only make payments through the banks. However, a decentralized system allows you to securely make transactions with another user without the need of a third-party like a bank.

    This feature opened the gateway for cryptocurrencies to enter into the financial world. The transparency of the Blockchain network makes it more vital.


    One of the common things that many people even dont understand today about Blockchain Technology is transparency. They are confused about transparency and privacy. Lets clarify everything here.

    The transparency feature allows everyone to see the transactions in the network. However, one cannot know the real identity of the person making the transaction, which is secured by cryptographic identity.


    What Is A Blockchain Platform

    A blockchain platform allows users and developers to create novel uses of an existing blockchain infrastructure. One example is Ethereum, which has a native cryptocurrency known as ether . But the Ethereum blockchain also allows the creation of smart contracts and programmable tokens used in initial coin offerings , and non-fungible tokens . These are all built up around the Ethereum infrastructure and secured by nodes on the Ethereum network.

    Proof Of Work Vs Proof Of Stake

    How to create a smart contract on Binance Smart Chain?

    A public blockchain functions through consensus mechanisms: the process for validating transactions without a third party like a bank.

    PoW and PoS are two such mechanisms. While their goalto reach a consensus that a transaction is validremains the same, how they get there is a little different.

    What Is PoW?

    PoW, the technical term for mining, is the original consensus mechanism. It is still used by Bitcoin and Ethereum as of writing but, as mentioned, Ethereum will move to PoS by 2022. PoW is based on cryptography, which uses mathematical equations only computers can solve.

    The example in the previous section of how blocks get added to the Bitcoin Blockchain explains this system.

    The two big problems with PoW are that it uses a lot of electricity and can only process a limited number of transactions simultaneously . Transactions typically take at least ten minutes to complete, with this delay increasing when the network is congested. Though compared to the days-long wait required to wire money across the globe, or even to clear a check, Bitcoins ten-minute delay is quite remarkable.

    Other consensus mechanisms were created to solve these PoW problems the most popular being PoS.

    What Is PoS?

    PoS still uses cryptographic algorithms for validation, but transactions get validated by a chosen validator based on how many coins they hold, also known as their stake.

    Blockchain: The Greatest Innovation Of The 21st Century

    With the ability to distribute data without being copied, Blockchain is considered to be the greatest innovation of the 21st century. Its the next big thing after the internet in the digital world. It is invented initially for solving the double-spending problem of cryptocurrencies. In this guide, you will understand what exactly Blockchain Technology is, how it works, what are the essential factors, and how you can use it to your advantage.

    Speed And Data Inefficiency

    Bitcoin is a perfect case study for the possible inefficiencies of blockchain. Bitcoins PoW system takes about 10 minutes to add a new block to the blockchain. At that rate, its estimated that the blockchain network can only manage about seven transactions per second . Although other cryptocurrencies such as Ethereum perform better than bitcoin, they are still limited by blockchain. Legacy brand Visa, for context, can process 24,000 TPS.

    Solutions to this issue have been in development for years. There are currently blockchains that are boasting more than 30,000 TPS.

    The other issue is that each block can only hold so much data. The block size debate has been, and continues to be, one of the most pressing issues for the scalability of blockchains going forward.
