What is blockchain? Its advantages and disadvantages and its applications in life

If you’ve been following banking, investing, or cryptocurrencies for the past ten years, you are probably familiar with blockchain on the network, the record-keeping technology behind bitcoin. And there’s a good chance it just makes so much sense. When trying to learn more about blockchain, you may have come across a definition like this: blockchain is a decentralized, distributed ledger. “The good news is, blockchain is actually easier to understand than it sounds.

What is blockchain?

If the technology is too complicated, why call it blockchain? At its most basic level, blockchain is really just a chain of blocks, but not in the traditional sense of those words. When we say words about block and blockchain in this context, we are really talking about digital information (block) stored in a public database (chain).

Blocks on blockchain are made up of pieces of digital information. Specifically, they have three parts:

  1. Block information about transactions, showing the date, time, and dollar amount of your most recent purchase from Amazon.
  2. Block stores information about who are participating in the transaction. A block for your purchase from Amazon records your name along with Amazon.com. Instead of using your real name, your purchase is recorded without any identifying information using a unique digital signature, a type of username.
  3. Blocks store information that distinguishes them from other blocks. Just like you and I have a name to distinguish us from each other, each block stores a unique code called a hash, which allows us to distinguish it from every other block. Tell you you made a purchase on Amazon, but while it’s in transit you decide that you can just resist and need a second. While the details of your new transaction look almost identical to your previous purchase, we are still able to differentiate blocks because of their unique tokens.

While the block in the example above is being used to store a purchase from Amazon, the reality is a bit different. A single block on the blockchain can actually store up to 1 MB of data. Depending on the size of the transactions, that means a block can hold several thousand transactions under one roof.

How does blockchain work?

When a block stores new data, it is added to the blockchain. Blockchain, as its name implies, consists of many blocks that are strung together. However, for a block to be added to the blockchain, four things must happen:

  1. A transaction must happen. Let’s continue with the example of an impulse purchase on your Amazon. After hastily clicking through multiple payment prompts, you go against your better judgment and purchase.
  2. That transaction must be verified. After making that purchase, your transaction must be verified. For other public information records, like the Securities and Exchange Commission, Wikipedia or your local library, there’s someone in charge of checking new data entries. With blockchain, however, that work is reserved for a network of computers. These networks typically consist of thousands (or in Bitcoin’s case, around 5 million) computers spread across the globe. When you make a purchase from Amazon, that network of computers hastily checks to see if your transaction is happening the way you say it. That is, they confirm the details of the purchase, including the transaction’s time, amount, and participant in the transaction.
  3. The transaction must be stored in a block. Once your transaction is verified as correct, it will be given a green light. The transaction’s dollar amount, your digital signature, and Amazon’s digital signature are all stored in one block. There, the transaction will likely join hundreds, or thousands of others liking it.
  4. That block must be given a hash function. Unlike an angel who earns his wings, once all block transactions have been verified, it must be provided with a unique identifier, called a hash. This block is also given the hash of the block most recently added to the blockchain. Once hashed, the block can be added to the blockchain.

When that new block is added to the blockchain, it becomes public to everyone – even you. If you take a look at Bitcoin’s blockchain, you will see that you have access to transaction data, along with information about when (playtime), in which (highways) and by whom (transfers followed by) is added to the blockchain.

Types of Blockchain

The Blockchain system is divided into 3 main categories:

Public

Anyone has the right to read and write data on Blockchain. The process of validating transactions on this Blockchain requires thousands or tens of thousands of nodes. Therefore, to attack this Blockchain system is impossible because the cost is quite high. Examples: Bitcoin, Ethereum.

Private

Users are only allowed to read data, not write permission because this belongs to an absolutely trusted third party. This organization may or may not allow users to read data under certain circumstances. The third party has the sole discretion to decide any changes on the Blockchain. Since this is a Private Blockchain, the transaction confirmation time is quite fast because only a small number of devices are required to validate the transaction. For example, Ripple is a Private Blockchain, this system allows 20% of the nodes to be fraudulent and only the remaining 80% to operate stably.

Permissioned

Also known as Consortium, a form of Private but adds a certain number of features, combining “belief” when participating in Public and “absolute trust” when participating in Private. For example: Banks or joint venture financial institutions will use Blockchain for themselves.

Versions of Blockchain

Blockchain 1.0 – Money and Payment

The main application of this version is cryptocurrency: includes currency conversion, remittances and the creation of digital payment systems. This is also the area most familiar to us that sometimes quite a lot of people mistake Bitcoin and Blockchain as one.

Blockchain 2.0 – Finance and Markets

Banking and financial processing: scaling Blockchain, bringing in financial and market applications. Assets include stocks, checks, debt, title and anything related to an agreement or a contract.

Blockchain 3.0 – Design and Monitor Operations

Bringing Blockchain beyond financial borders, and into fields like education, government, health, and the arts. In these areas, there will be multiple types like physical, digital or human in nature.

Consensus mechanism in Blockchain

The consensus mechanism in Blockchain can be understood as the way in which Byzantine generals can reach consensus to win together. The following are common types of consensus mechanisms:

Proof of Work

Popular in Bitcoin, Ethereum, Litecoin, Dogecoin and most cryptocurrencies. Consumes quite a lot of electrical energy.

Proof of Stake

Popular in Decred, Peercoin and in the future is Ethereum and many other cryptocurrencies. More decentralized, consumes less energy and is not easily intimidated.

Delegated Proof-of-Stake.
Popular in Steemit, EOS, BitShares. Cheap transaction costs; extendable; high energy efficiency. However, there is still a bit of focus because this algorithm selects a trusted person to authorize.

Proof of Authority.
This is a centralization model commonly seen in POA.Network, Ethereum Kovan testnet. High performance, good scalability.

Proof-of-Weight (Proof of Mass / Greater is better)

  • Popular in Algorand, Filecoin. Customizable and well scalable. However, the development process will be a big challenge.
  • Byzantine Fault Tolerance (Byzantine Anti-Fraud Consensus Byzantine Generals Siege Blockchain).
  • Popular in Hyperledger, Stellar, Dispatch, and Ripple. High productivity; low cost; extendable. However, it is still not completely reliable.

This algorithm has 2 versions:

Practical Byzantine Fault Tolerance (Anti-fraud consensus / Byzantine General surrounded Blockchain in practice).
Federated Byzantine Agreement (Byzantine Alliance by Consensus).
Directed Acyclic Graphs (Topological Algorithm).
Often seen in Iota (Tangle technology), Hashgraph, Raiblocks / Nano (Block-lattice technology), is a competitor of Blockchain.

Main features of BlockChain

A distributed database

Imagine a spreadsheet that is duplicated thousands of times through a network of computers, which is designed to update the spreadsheet on a regular basis so that you can understand the basics of blockchain.

Information held on a blockchain exists as a continuously harmonized and shared database. Here’s how to use the network with obvious benefits. The blockchain database is not stored in a single location, meaning that the records are stored in a public, easy to verify. No centralized version of this database exists, so hackers have no chance of attacking it either. Blockchain is stored by millions of computers at the same time, its data can be accessed by anyone on the Internet.

Blockchain sustainability

Blockchain technology is like the Internet because it has a built-in power. By storing the same blocks of information on its network, blockchain cannot:

Controlled by any one entity

There is no single flaw or error.

Bitcoin was released in 2008, ever since, the Bitcoin blockchain has been operated, operating without any significant disruption. To this point, any problems related to Bitcoin are caused by hacking or poor management. In other words, these problems come from bad intentions and human error, not Bitcoin’s own flaws.

The internet has proven durable for nearly 30 years. This is a good track record for blockchain technology as it continues to be developed

A network of nodes

A network of computational nodes that make up the blockchain. The node here is a computer connected to the blockchain network that uses a client to confirm and forward transactions. The node will receive a copy of the blockchain, which is loaded automatically when joining the blockchain network.

Together, these nodes create a powerful tier 2 network, a completely different perspective on how the Internet might work. Each node is an “administrator” of the blockchain network and automatically participates in the network, the driving force for this participation is the chance to win Bitcoin.

Nodes are also known as Bitcoin mining, but the terminology is a bit misleading. In fact, each of them is competing for Bitcoin by solving puzzles. Bitcoin has been the “life” of blockchain since its inception. Bitcoin is only being recognized as a very small part of the potential of blockchain technology.

Security

By storing data on its network, blockchain eliminates the risks associated with centrally organized data. Its network has no vulnerabilities. Meanwhile, the security issue on the Internet is becoming more and more complex. We all rely on the username / password system to protect our identities and assets online, but the system is still more likely to break. Blockchain’s security method uses encryption technology with public / private key pairs. The public key (a long string of random numbers) is the address of the user on the blockchain.

Bitcoin sent over the network will be recognized as belonging to that address. The private key is like a password, allowing the holder to gain access to Bitcoin or other digital assets. Store data on the blockchain and it will not be damaged. This is true, although protecting your digital assets will require the security of your private key by printing it out, creating a digital wallet to hold like a paper wallet.

Transparent and unbreakable

The blockchain network exists in a state of agreement, checking automatically every 10 minutes. A kind of digital value self-controlled ecosystem, the network will regulate every transaction that happens in about 10 minutes. Each of these groups of transactions is called a block. Two important features are drawn from here:

  • Transparency: Data is embedded in the network as a public, block.
  • It cannot be corrupted: Changing any unit of information on the blockchain means using a large number of computers to overwrite the entire network.
  • In theory, this could happen. In fact, it doesn’t happen. For example, controlling the system to take over Bitcoin will ruin its value.

The idea of ​​decentralization

By design, blockchain is a decentralized technology. Whatever happens on it is a function of the network. Some important suggestions stem from this. By creating a new way to confirm transactions aspects of traditional commerce may become unnecessary. Transactions on the stock market, for example, can be carried out on the blockchain at the same time, or can be stored as a red book, completely public. And the decentralization has come true.

The global computer network uses blockchain technology to jointly manage the database and record Bitcoin transactions. That is, Bitcoin is managed by its network and no one is central. Decentralized means the network operates on a user basis, or P2P. Possible forms of collective cooperation have only just begun to be explored.

Is blockchain private?

Anyone can view the content of the blockchain, but users can also choose to connect their computer to the blockchain network. In doing so, their computers receive a copy of the blockchain that is updated automatically every time a new block is added, just like a Facebook news feed that updates live every time a new state is available. to post.

Every computer in the blockchain network has its own copy of the blockchain, which means there are thousands or, in Bitcoin’s case, millions of copies of the same blockchain. Although every copy of the blockchain is identical, spreading that information across a computer network makes it harder to manipulate. With blockchain, having a single, definitive account of events can be manipulated. Instead, a hacker would need to manipulate every copy of the blockchain on the network.

However, looking through the Bitcoin blockchain, you will notice that you do not have access to identify information about the user making the transaction. Although transactions on the blockchain are not completely anonymous, personal information about users is limited to their digital signature or username.

This raises an important question: if you cannot know who is adding blocks to the blockchain, how can you trust the blockchain or the computer network that sustains it?

Is blockchain secure?

Blockchain technology for security and trust issues in many ways. First, new blocks are always stored linearly and over time. That is, they are always added to the end of the blockchain game. If you look at the Bitcoin blockchain, you will see that each block has a position on the chain, called the height of the user. At the time of writing, the most recent block’s height was 548,015, meaning it was block 548,015 to be added to the blockchain.

Once a block has been added to the end of the block chain, it is difficult to go back and change the content of the block. That’s because each block contains its own hash, along with the hash of the block before it. Hash codes are generated by a mathematical function that turns digital information into a string of numbers and letters. If that information is edited in any way, the hash code changes as well.

Here, why is that so important to security. Let’s say a hacker tries to edit your transaction from Amazon so that you actually have to pay for your purchase twice. As soon as they edit the dollar amount in your transaction, the block hash will change. The next block in the chain will still contain the old hash, and the hacker will need to update that block to hide their traces. However, doing so will change that block of hash.

Then, to change a single block, a hacker would need to change every single block after that block. Recalculating all those hashes will take a huge amount of computation power. In other words, once a block is added to the blockchain, it becomes very difficult to edit and impossible to delete.

To solve the problem of trust, blockchain networks deployed experiments for computers that wanted to join and add blocks to the chain. The tests, known as the user consensus model, directly require users to prove themselves before they can join the blockchain network. One of the most common examples used by Bitcoin is called proof of work.

In proving the system works, the computers have to prove that they have done Google’s job by solving a complex computational problem. If a computer solves one of these problems, they become eligible to add a block to the blockchain. But the process of adding blocks to the blockchain, what the crypto world calls network mining, is not easy. In fact, according to blockchain news site BlockExplorer, the rate of solving one of these problems on the Bitcoin network is around 1 in 7 trillion at the time of writing. To solve the complex math problems of those odds, computers have to run programs that consume a considerable amount of energy and energy.

The proof of work doesn’t make the hacker attacks impossible, but it makes them somewhat useless. If a hacker wanted to coordinate an attack on the blockchain, they would need to solve complex computational problems at a scale of 1 in 7 trillion like everyone else. The cost of organizing such an attack will almost certainly far outweigh the benefits.

What is the difference between Blockchain and Bitcoin?
The goal of blockchain is to allow digital information to be recorded and distributed, but not edited. That concept can be difficult to cover our heads without seeing the technology work, so let’s see how the earliest application of blockchain technology actually works.

Blockchain technology was first sketched in 1991 by Stuart Haber and W. Scott Stornetta, two researchers who wanted to implement a system where the document timestamp could not be tampered with. But that was not until almost two decades later, with the launch of Bitcoin in January 2009 that the blockchain had its first real-world application.

The Bitcoin protocol is built on the blockchain. In a research article introducing the digital currency, fake Bitcoin creator Satoshi Nakamoto called it a new cryptocurrency system, which is fully peer-to-peer, with no trusted third parties.

Here, how it works.

You have all these people, all over the world, who have Bitcoin. According to a 2017 study by the Cambridge Center for Alternative Finance, the number could reach 5.9 million. Let’s say one out of 5.9 million people wants to spend their Bitcoin on groceries. This is where blockchain comes in.

When it comes to printed money, the use of printed money is regulated and verified by a central authority, usually a bank or government – but Bitcoin is not controlled by anyone. Instead, transactions carried out in Bitcoin are verified by a network of computers.

When one person pays another for goods in Bitcoin, computers on the Bitcoin network race to verify the transaction. To do so, the user runs a program on their computer and tries to solve a complex mathematical problem, called a transaction hash. The completed transaction is recorded and publicly stored as a block on the blockchain, at which point it becomes immutable. In the case of Bitcoin and most other blockchains, computers successfully verify blocks that are rewarded for their labor in cryptocurrency.

Although transactions are publicly recorded on the blockchain, user data is not – or, at least, incomplete. In order to make transactions on the Bitcoin network, participants must run a program called wallets. Each wallet consists of two unique and separate cryptographic keys: a public key and a private key. The public key is the location where transactions are deposited and withdrawn from. This is also the key that appears on the blockchain ledger as the user’s digital signature.

Even if a user receives a Bitcoin payment to their public key, they will not be able to withdraw them with their private partner. A user’s public key is a reduced version of their private key, generated through a complex mathematical algorithm. However, due to the complexity of this equation, it is almost impossible to reverse the process and generate the public key private key. For this reason, blockchain technology is considered confidential.

Public key and private key ELI5

You can think of a public key as a field key and a private key as a combination of keys. Teachers, students and even your lover can insert letters and notes through the opening in your locker. However, the only person who can access the contents of the mailbox is the person with the unique key. However, it should be noted that while the school’s key combinations are kept in the main office, there is no central database keeping track of the private keys of the blockchain network. If a user mistakenly sets their private key, they lose access to their Bitcoin wallet, which is considered a bonus for Bitcoin holders.

In the Bitcoin network, blockchain is not only shared and maintained by a public network of users – it is also negotiated. When a user joins the network, their connected computer receives a copy of the blockchain that is updated whenever a new block of transactions is added. But what if, through human error or the attempt of a hacker, a user of a copy of the blockchain is manipulated to be different from every other copy of the blockchain?

The blockchain protocol discourages the existence of multiple blockchains through a process called Google consensus. With the presence of many different copies of the blockchain, the consensus protocol will adopt the longest chain available. More users on a blockchain means blocks can be added to the end of the chain faster. According to that logic, the blockchain of record will always be the thing most trusted by the user. The consensus protocol is one of blockchain technology’s greatest strengths, but also allows for one of its biggest weaknesses.

Theoretically, hackers can take advantage of the majority rule in a 51% attack. Here’s how it would happen. Let’s say there are 5 million computers on the Bitcoin network, which is definitely not enough but one number is easy to divide. To gain a majority on the network, a hacker would need to control at least 2.5 million and one of those computers. In doing so, an attacker or group of attackers can interfere with the process of recording new transactions. They can send a transaction – and then reverse it, making it appear as if they still have the coins they just spent. This vulnerability, known as double spend, is the digital equivalent of a perfect counterfeit and will allow users to spend their Bitcoin twice.

Such an attack is extremely difficult to execute against a blockchain of Bitcoin size, as it would require an attacker to gain control of millions of computers. When Bitcoin was first established in 2009 and its number of users was numbered in the tens, it would be easy for an attacker to control the majority of the computing power in the network. This defining feature of blockchain has been flagged as a weakness for fledgling cryptocurrencies.

Users fearing 51% attacks could actually limit the monopoly that forms on the blockchain. In “Digital Gold: Bitcoin and the Inner Story of the Lost and Millionaires Trying to Reinvent Money” (English: Digital Gold: Bitcoin and the Inside Story of the Misfits and Millionaires Trying to Reinvent Money) New York Times journalist Nathaniel Popper writes about how a group of users, known as Bit Bitury, together create thousands of high-powered computers a competitive edge on blockchain. Their goal was to mine as many blocks as possible and earn bitcoins, which at that time was worth about $ 700 per block.

However, by March 2014, Bitfury was positioned to exceed 50% of the total computing power of the blockchain network. Instead of continuing to increase their holdings online, the group was elected to self-regulate and vowed never to exceed 40%. Bitfury knows that if they choose to continue to increase control of their network, the value of bitcoin will decrease as users sell off their funds in response to the possibility of a 51% attack. In other words, if the user loses trust in the blockchain network, the information about that network risk becomes completely worthless. Blockchain users can then only increase their computing power to a point before they start to lose money.

How can blockchain be used in the real world?

Blocks on the blockchain store data about currency transactions – we’ve eliminated that. But it turns out that blockchain is actually quite a reliable way of storing data about other types of transactions. In fact, blockchain technology can be used to store data about asset exchanges, stop in the supply chain, and even vote for a candidate.

Deloitte recently surveyed 1,000 companies across seven countries about integrating blockchain into their businesses. Their survey shows that 34% already have a blockchain system in production today, while another 41% are expected to deploy a blockchain application within the next 12 months. Additionally, nearly 40% of the companies surveyed reported that they would invest $ 5 million or more in blockchain over the next year. Here are some of the most popular uses of blockchain that are being explored today.

Bank

Perhaps no industry has benefited more from integrating blockchain into its business than banks. Financial institutions operate only during business hours, five days a week. That means if you try to deposit a check on a Friday at 6pm, you will likely have to wait until Monday morning to see that money hit your account. Even if you make a deposit during business hours, the transaction can still take 1-3 days to verify due to the sheer volume of transactions banks need to settle. Blockchain is different, never sleeps. By integrating blockchain into a bank, consumers can see their transactions processed in at least 10 minutes, essentially the time it takes to add a block to the blockchain, regardless of time or day of the day. week. With blockchain, banks also have the opportunity to exchange money between institutions more quickly and securely. In stock trading, for example, the clearing and settlement process can take up to three days (or longer, if banks do international transactions), meaning money and stocks are frozen in that time.

Given the size of the funds involved, even within a few days the money is transferred can bring significant costs and risks to banks. Santander, a European bank, places potential savings at $ 20 billion per year. Capgemini, a French consultant, estimates that consumers can save up to $ 16 billion in banking and insurance fees each year through blockchain-based applications.

Cryptocurrencies

Blockchain forms the foundation for cryptocurrencies like Bitcoin. As we discovered earlier, currencies like the US dollar are regulated and verified by a central authority, usually banks or governments. According to the central authority system, the user’s data and currency are technically anytime their banks or governments. If a user bank collapses or they live in a country with unstable government, the value of their currency is at risk. These are the worries about Bitcoin being born. By spreading its operations across a network of computers, blockchain allows Bitcoin and other cryptocurrencies to operate without the need for a central authority. This not only reduces risk, but also eliminates many processing and transaction fees. It also gives people in non-volatile countries a more stable currency with more applications and a wider network of individuals and organizations with which they can trade, both in country and international (at least, this is the goal.)

Health care

Healthcare providers can leverage blockchain to securely store their patient records. Once a medical record is created and signed, it can be written to the blockchain, providing the patient with evidence and confidence that the record cannot be altered. These personal health records can be encrypted and stored on the blockchain using a private key, so they can only be accessed by a limited number of individuals, thus ensuring privacy.

Property records

If you’ve ever gone to the ward to do paperwork, you’ll know that the claiming process is both cumbersome and ineffective. Today, an actual deed must be sent to a government employee at the ward, where it is manually entered into the ward’s central database and public index. In the case of a property dispute, the claims against the property must be compared with the publicity index. The process is not only costly and time consuming – it is also deceived by human error, where each inaccuracy makes tracking property ownership ineffective. Blockchain has the potential to eliminate the need to scan documents and track physical files on the ward. If ownership of an asset is stored and verified on the blockchain, the owner can be confident that their actions are accurate and permanent.

Smart contract

A smart contract is a computer code that can be built into a blockchain to facilitate, verify, or negotiate a contract agreement. Smart contracts work under a set of conditions that the user agrees to. When those conditions are met, the terms of the agreement will be executed automatically.

For example, I rented you my apartment with a smart contract. I agree to provide you with the apartment door number as soon as you pay me the security deposit. We will both send a portion of our agreement to the smart contract, which will keep and automatically exchange my door code for your security deposit on the rental date. If I do not provide the door code before the rental date, the smart contract will refund your deposit. This eliminates the fees commonly associated with using a notarized or third-party mediator.

Supply chain

Vendors can use blockchain to record the source of documents they purchased. This will allow companies to verify the authenticity of their products, along with health and ethics marks.

Vote

Voting with blockchain has the potential to eliminate electoral fraud and increase voter turnout, as was tested in the November 2018 midterm elections in West Virginia. Each vote will be stored as a block on the blockchain, making them nearly impossible to tamper with. The blockchain protocol will also maintain transparency in the electoral process, reduce the staffing needed to conduct elections, and provide officials with instant results.

What are the advantages of Blockchain?

For all its complexity, the potential for blockchain, as a decentralized form of record storage, is almost limitless. From greater user privacy and enhanced security, to lower processing fees and fewer errors, blockchain technology can very clearly see applications beyond those outlined above. Here are the blockchain selling points for businesses on the market today.

Accuracy

Transactions on a blockchain network are approved by a network of thousands or millions of computers. This eliminates nearly all human involvement in the verification process, resulting in fewer human errors and a more accurate record of information. Even if a computer on the network makes a computational error, the error will only happen with one copy of the blockchain. In order for that error to spread to the rest of the blockchain, it needs to be done by at least 51% of the network’s computers – something impossible.

Price

Usually, consumers pay a bank to verify a transaction, a notary to sign a document or a minister to perform a marriage. Blockchain eliminates the need for third-party verification and, with it, their associated costs. Business owners incur a small fee whenever they accept credit card payments, for example, because banks have to process those transactions. Bitcoin, on the other hand, has no central authority and virtually no transaction fees.

Decentralization

Blockchain does not store any of its information in a central location. Instead, the blockchain is copied and spread across a network of computers. Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change. By spreading that information over a network, instead of storing it in a central database, the blockchain becomes more difficult to tamper with. If a single copy of the blockchain falls into the hands of a hacker, a single copy of information, rather than the entire network, will be compromised.

High efficiency

Transactions placed through a central authority can take up to several days to process. For example, if you try to deposit a check on a Friday night, you might not actually see the funds in your account until Monday morning. While financial institutions operate during business hours, five days a week, blockchain operates 24 hours a day, seven days a week. Transactions can be completed in about ten minutes and can be considered secure in as little as a few hours. This is especially useful for cross-border transactions, which often take longer due to time zone issues, and the fact that all parties have to confirm payment processing.

Private

Many blockchain networks act as public databases, meaning anyone with an internet connection can see a list of the network’s transaction history. While users can access details about transactions, they cannot access identifying information about the users making those transactions. It is a common misconception that blockchain networks like bitcoin are anonymous, when in reality they are just secrets. That is, when users conduct public transactions, their unique code called the public key is recorded on the blockchain, instead of their personal information. Even though a person’s identity is still linked to their blockchain address, this prevents hackers from obtaining the user’s personal information, as could be the case when banks are hacked.

Protect

Once a transaction is recorded, its authenticity must be verified by the blockchain network. Thousands or even millions of computers on the blockchain rush to confirm that the purchase details are correct. After a computer has validated the transaction, it is added to the blockchain as a block. Each block on the blockchain contains its own unique hash, along with the unique hash of the block before it. When information about a block is edited in any way, that block of hash code changes – however, the hash code on that block will not be changed. This discrepancy makes information about the blockchain extremely difficult to change without prior notice.

Transparency: although personal information on the blockchain is kept private, the technology itself is almost always open source. That means users on the blockchain network can modify the code as they see fit, as long as they have the majority of the network’s computing power. Keeping data on blockchain open source also makes data tampering much more difficult. With millions of computers on the blockchain network, for example, at any given moment, surely no one can make a change unnoticed.

What are the disadvantages of Blockchain?

Despite significant strides towards blockchain, there are also significant challenges to its adoption. The barrier to the application of blockchain technology today is not just technical. Most of the challenges are really political and regulatory, saying nothing for the thousands of hours of custom software design and back-end programming required to integrate blockchain into existing business networks. Here are some of the challenges of how blockchain is widely adopted.

Price

While blockchain can save users money in transaction fees, the technology is not free. For example, the proof of work of the system Bitcoin uses to validate transactions consumes a large amount of computational power. In the real world, the power from millions of computers on the bitcoin network is close to what Denmark consumes every year. All that energy costs money, and according to a recent study from research firm Elite Fixture, the cost of mining a single bitcoin varies significantly by location, from just $ 531 to a worthy $ 26,170. amazing. Based on average US utility costs, that figure is closer to $ 4,758. Despite the cost of mining bitcoin, users continue to increase their electricity bills to validate transactions on the blockchain. That’s because when miners add a block to the bitcoin blockchain, they are rewarded with enough bitcoins to make their time and energy worthwhile. However, when it comes to blockchains that do not use cryptocurrencies, miners will need to be paid or incentivized to validate transactions.

Inefficient

Bitcoin is a perfect case study for blockchain’s possible inefficiency. Bitcoin’s proof of work takes about ten minutes to add a new block to the blockchain. At that rate, it was estimated that the blockchain network could only manage seven transactions per second (TPS). Although other cryptocurrencies like Ethereum (20 TPS) and Bitcoin Cash (60 TPS) outperform bitcoin, they are still limited by blockchain. The legacy brand visa, for context, can handle 24,000 TPS.

Private

While the security on the blockchain network protects users from hacking and protects privacy, it also allows for illegal transactions and activities on the blockchain network. The most cited example of blockchain being used for illegal transactions is perhaps Silk Road, a dark online marketplace that operated from February 2011 to October 2013 when the FBI arrested. website owner. The website allows users to browse the website without being tracked and make illegal purchases in bitcoin. Current US regulations prevent users from exchanging online, like those built on blockchain, from complete anonymity. In the United States, online exchanges must obtain information about their clients when they open accounts, verify the identity of each client, and confirm that the client does not appear in any list of nests. any known or suspected terrorist organization.

Protect

Several central banks, including the Federal Reserve, the Bank of Canada and the Bank of England, have opened investigations into digital currencies. According to the Bank of England Research Report February 2015, further research will also be required to create a system that can use distributed ledger technology without compromising currency controls. central bank protection and system protection against system attacks.

Hypersensitivity

Newer cryptocurrencies and blockchain networks are vulnerable to 51% attacks. These attacks are extremely difficult to execute due to the computational power required to gain control of a majority of the blockchain network, but Joseph Boneau, NYU computer science researcher, said that could change. Boneau published a report last year estimating that 51% of attacks were likely to increase, as hackers can now simply hire computing power, instead of buying all the devices.

What’s next for Blockchain?

First proposed as a research project in 1991, blockchain is comfortably settling in its twenties. Like most millennia, blockchain has seen its fair share of the past two decades, with businesses around the world speculating about what the technology is capable of and where it is. looking forward in the coming years.

With many practical applications for the technology being deployed and explored, blockchain finally made a name at the age of twenty-seven, in no small part because of bitcoin and cryptocurrency. As a buzzword on every investor’s tongue in the country, blockchain stands out to make business and government more accurate, efficient and secure.

As we prepare to enter the third decade of blockchain, it is no longer a question of “if” the legacy companies will catch up with the technology – it’s a question of “when”.

Bitcoin Will Be The Ultimate Winner After the US Elections

Famous TV host Max Keiser explains how Bitcoin will emerge as the ultimate winner, despite who wins the 2020 US Presidential elections.

Occurring every four years, the US Presidential elections gain attention not only from US citizens but from the entire world. Being the largest country by nominal GDP and the US dollar serving as the global reserve currency, the consequences of elections’ results will be felt in the next (at least) four years everywhere.

That “everywhere” part definitely includes the traditional financial markets and, more specifically, the US stock markets. In fact, their performance could even hint who might end up as the 46th US president.

According to Strategas Research Partners’ Dan Clifton, every president who had averted a recession during the two years leading to the elections has remained in office. Only Calvin Coolidge managed to win the reelection despite the 1920s economy hurdles.

The New York Times claimed that the US economy officially entered a state of recession in February 2020. With that, the question remains if President Trump will join President Coolidge as an exception to the rule or will history repeat itself and Joe Biden will come to power.

Some More History

Speaking of history, Forbes recently noted that the stock markets have “performed better during a year when an incumbent president is elected compared to a new administration.” The data is conclusive – the elections have a direct impact on the stock markets.

With that in mind, the cryptocurrency community has raised the question of if or how the elections will impact a currency operating outside the traditional financial infrastructure – a currency existing in the digital world going by the name Bitcoin.

During its relatively short existence, Bitcoin has gone through two US elections – in 2012 and in 2016. Although they weren’t so long ago, most community members agree that the asset was too small to feel the consequences. However, that’s not the case in 2020.

So, what could happen if President Trump, who has openly criticized the whole cryptocurrency industry, remains in office? Or, what could transpire if the former Vice President Joe Biden takes charge?

The community’s opinions slide in either direction but not Max Keiser. The popular TV host believes that Bitcoin is not correlated to any political parties or outcomes because it’s backed by “insatiable hunger.” As such, he recently told CryptoPotato that Bitcoin wins either way, but with different styles.

Trump Wins: How Could That Possibly Be Good For BTC?

Trump’s presidency has been filled with somewhat controversial actions and statements, to say the least. Those range from planning to build a physical wall with Mexico to keep migrants away to threatening his 2020 opponent Joe Biden with physical assault.

However, his views on Bitcoin have been consistent and unfavorable. In July 2019, he said that he’s “not a fan of Bitcoin and other Cryptocurrencies, which are not money, and whose value is highly volatile and based on thin air.”

An unpublished book written by Trump’s former national security advisor John Bolton claimed that the President urged Treasury Secretary Steve Mnuchin to “go after Bitcoin” a year prior to his assertions mentioned above.

With that being said, it’s hard to imagine that President Trump will suddenly have a change of heart and start supporting the first-ever (or any other) cryptocurrency. So, if he wins the elections, the effects on Bitcoin could be rather adverse, right?

Well, that’s not what Max Keiser believes. He told us that “with Trump, who at least understands something about capitalism, the ascent of Bitcoin would be slower as I believe he would calm markets by having the US enter the global hash war that Iran now leads in a Sputnik-like call to enter the Hash Race moment.”

Keiser added that the US needs to strive for a “big slice of Bitcoin’s global hash rate before our competitors do. I know of several countries that will soon announce major sovereign underwritings of BTC hash rate to try and oust Iran’s position.”

What Will Happen To Bitcoin if Biden Wins?

The democratic party’s presidential candidate was involved in the infamous Twitter hack earlier this year. Shortly after, he said that he doesn’t own any bitcoins but hasn’t made any decisive comments about the cryptocurrency. As such, it would be more difficult to argue whether or not his presidency would be ultimately good for Bitcoin.

Keiser’s views see BTC sharply explode in value in case Biden emerges the winner come Sunday.

“As I’ve said, a Biden win would accelerate Bitcoin’s advance as panic-buying from those looking to escape the socialists, money printers, and MMT’ers goes into hyperdrive.”

“It will be like the 1938’s Kristallnacht (also known as the Night of Broken Glass or the November Pogrom), jack-booted armed thugs will go door-to-door stealing property in the name of social justice.”

Max Keiser: Bitcoin Wins No Matter What

Bitcoin is bigger than the elections, asserted Keiser. It’s an asset that has no real “correlation with anything – stocks, bonds, currencies, gold, commodities, or property – and certainly no political parties or political outcomes, here in the US or anywhere in the world.” Bitcoin is correlated only to Bitcoin.

XRP is paralyzed from a technical standpoint while the sell setup of TD9 is triggered on the daily chart

XRP continues to lag behind the rest of the market after a brief glimmer of hope that has brought prices to current levels by the end of July. will outweigh Bitcoin and Ethereum, then a sell setup that is activated on the daily timeframe could cause it to drop in price.

XRP is paralyzed

Throughout the past month, XRP has struggled to gain any sustained momentum as it fluctuated between $ 0.22 and $ 0.26. The upper boundary of this range is quite harsh, with every visit here denied.

One analyst believes XRP is paralyzed from a technical standpoint, with a lack of buying pressure not allowing it to match the dynamics seen by the synthetic cryptocurrency market.

He is currently looking to ease his long positions as soon as the cryptocurrency reaches the next key resistance level.

“This dumb thing moved 2% while everything moved 10%. I… hate this coin and want to sell the first resistance. Everything moves exponentially in comparison to XRP. It was paralyzed. ”

Sell ​​setup of TD9 trigger on XRP daily chart

There are hundreds of technical analysis indicators available to analysts and traders – some are new and customized while others have been around for decades and built with financial market icons. .

One such tool is the TD Sequential indicator, one of the most accurate of all cryptocurrencies, TD Sequential stands for Tom DeMark’s name, TD Sequential usually has 2 components – TD Setup and TD Countdown. The first phase of TD Sequential starts with TD Setup and has a total of 9 counts (TD 9). After 9 counts, at that point the price will stop, either retrace or reverse exactly to that level. But that is also the point where TD Sequential begins a second phase called TD Countdown and is counted 13 times (TD 13). When the 13th count is completed, at that point the price will reverse or just a small recovery.

It has successfully cut some Bitcoin tops and bottoms and performs well in altcoins and traditional markets. The indicator offers a sell setup after a series of candlesticks closes in response to a set of specific requirements.

Usually, the sell setup of TD9 comes after a series of bulls. In XRP, however, the gain is just enough to trigger TD9, but only at a low level.

Most of the price action in XRP / USD is sideways on both the daily and weekly charts. The lack of a powerful higher thrust has resulted in what is known as an “imperfect” setup.

Only when a higher level is established above 8 or 9 candles will the setup be considered “perfect”.

Weekly chart

While there is enough gain in the daily price chart to trigger a sell setup, the weekly timeframe miniaturization shows how stagnant XRP has been trading.

There are currently a total of 6 weekly candles whose real body closes within the 6% range. Usually when sideways properties for a long time, a big decisive move will result.

A strong move upwards will complete an inverse head-shoulder pattern on the weekly timeframe and begin to form an even larger right shoulder on the monthly timeframe.

For now, one thing getting in the way is the sell-daily TD 9 setup, which is most likely the start of a deeper correction. However, due to prolonged sideways and imperfect selling setup, higher gains cannot be ruled out.

Charlie Lee – Litecoin is moving to private money (privacy coin)

Litecoin (LTC), Bitcoin’s most famous and oldest hard fork coin, is focusing on one new feature: privacy.

The blockchain industry’s subdivision of “private money” – with embedded technology that protects identifiable information from the public view – is becoming one of the hottest spots this year. One of the largest privacy coins, Zcash (ZEC), which offers protected transaction capabilities, has nearly tripled so far since the beginning of 2020, while Monero (XMR), using one techniques called “ring signatures” to obscure the sender’s and receiver’s data have also doubled.

Litecoin founder Charlie Lee said in a recent interview with Coindesk that the project is now looking to adopt privacy-enhancing features, which he finds increasingly appealing to crypto users. . Improvements are being tested and are expected to upgrade to the mainnet next year.

If the effort succeeds, it could put a little bit of enthusiasm into a project that is lacking momentum in the cryptocurrency market. Litecoin is up 21% this year after rising 38% in 2019, less than bitcoin’s 60% annual gain and its own 94% gain last year.

“I want to make it so that users don’t have to worry about giving up their financial privacy using litecoin,” Lee said. “Even if you don’t do anything illegal, you don’t want people to know how much money you have or what your salary is.”

An innate feature of blockchain technology is that the transfer of cryptocurrencies over computer networks is often visible to anyone with Internet access, making it easy to track and monitor specific wallet addresses – and sometimes traces those addresses back to identifiable entities.

So digital asset developers have been working for years to invent new ways to preserve blockchain’s advantages – the ease and speed of money transfers without banks as intermediaries – without apparent transparency.

Such features become even more desirable as regulators and law enforcement intensify oversight of crypto trading and compliance with tax and anti-money laundering rules. .

Lee, a former software engineer at Google and Coinbase, who led Litecoin, is a closely watched entrepreneur, partly because his experience dates back to the early years of cryptocurrencies, after bitcoin came out. eyes in 2009.

Litecoin is often referred to as the silver versus the gold of bitcoin, and it has been used historically as a basis for testing technologies that would later become the backbone of larger blockchain networks, including bitcoin. The network processes new blocks of data 4 times faster than the Bitcoin system, but its smaller size makes it less secure.

New security features are designed to work in line with the increasingly stringent compliance of crypto exchanges with global regulators.

Litecoin is relying on a technology called Mimblewimble, which helps reduce the amount of data that is publicly visible on the main blockchain network, through the use of expansion blocks that hide inputs and outputs.

It remains unclear whether regulators will proceed to restrict the use of security features that can be used to conceal illegal transfers or tax evasion.

Both Zcash and Monero, including direct privacy on the protocol, have faced legal pressures. Europol, a European Union law enforcement agency, recently declared privacy technologies, including privacy-focused coins, the leading threat in criminal assessment. organized crime on the Internet.

In 2019, exchange Coinbase delisted Zcash in the UK without giving a reason, but speculation immediately focused on the digital currency’s identity protection features.

For Litecoin, this could be another opportunity to differentiate it from Bitcoin, which has already attracted the attention of many cryptocurrency traders as a hedge against inflation.

Lee told news agency CoinDesk during a video chat: “I don’t think bitcoin will follow this path of what we’re doing, as it’s a bit drastic. In other words, litecoin has a lot to prove. “
