Presenting the ultimate Blockchain guide
Blockchain is among the technologies capable of revolutionizing numerous industries regardless of their nature and functionality. Be it banking, transaction, or construction, blockchain proposes benefits for every sector.
Several industries are picking up on the trend of integrating blockchain, but there are still many who do not have any clue about it. That is why the web is filled with questions like “what is blockchain”, “benefits of blockchain”, and “why choose blockchain.”
Studies have even shown that around 59% of the people have never even heard the term blockchain technology. Even the ones who have heard the term have no clue as to what it actually is. A tech with such potency remaining dormant is a crime to evolution. That is why we are presenting the ultimate beginner’s guide to blockchain:
The History of Blockchain
Invented by Satoshi Nakamoto in the year 2009, the tech opened the paths for the evolution of digital currency. The best thing about blockchain technology is that it got smart contracts into the mainstream arena.
Still the traces of blockchain go as far as 1991, when Scott Stornetta and Stuart Haber worked on a crypto-secured chain of blocks. Despite the work continuing throughout the 2000s, it was in 2008 when Satoshi brought the ideas into the real world.
What Made Blockchain Popular?
It was the anonymous nature of blockchain, which earned it the initial popularity boost. The factor helped Bitcoin gain relevance in the market; however, it was transparency that helped the technology grow.
Decentralization is amidst one of the first features every business presents blockchain with. However, the technology does not have a single form. While Bitcoin is merely a crypto coin, Ethereum serves as a ledger tech.
Therefore, choosing one quality to highlight blockchain will be unfair.
Myths about Blockchain
There are numerous myths surrounding blockchain, and here we have busted a few of them.
Myth 1: Blockchain is Bitcoin or vice-versa
It simply is not true. Blockchain is a much wider term while Bitcoin is merely an offspring of the tech.
Myth 2: Blockchain is Foolproof
No technology in the entire world is absolutely secure. However, in order to breach the system, you need to gain access to over 50% of the network’s capacity.
Myth 3: Blockchain offers 100 Percent Security
Even with the seemingly unbreachable concept of blockchain, some loopholes still exist. One such example is Ethereum breach, which later forced Ethereum to be divided into two categories.
What is Blockchain?
You can define blockchain as a decentralized, digitized, and distributed database of networks, which are interconnected. An entry on one system is recorded in every system as the database is copied and distributed to every participant. Meaning every participant knows exactly what is going on in the network, facilitating a highly-transparent ecosystem.
One major aspect favoring the blockchain industry is the sheer intricacy of data modification. Once you have inputted the knowledge, modifying it becomes seemingly impossible as you need the agreement of every involved member.
Moreover, every participant is notified regarding the changes made to the system, allowing everything to stay transparent. What a participant owns at any moment can be called the blockchain’s current state.
The state is constantly updated with new blocks getting added within the chains.
What Role a Peer-to-Peer Network Plays in Blockchain
Blockchain technology establishes a global network via numerous computers downloading and synchronizing the data. The computers are termed nodes and they utilize the peer-to-peer network for securely sharing the data.
When you add new blocks within the blockchain, every node updates the blockchain. Here are some of the benefits of using peer-to-peer network,
- 24/7 testing ability
- No interdependency for checking
- Low chances of breach
- No chances of deleting every node
Why Use the Agreement Mechanism
Even if the nodes do not trust each other, a peer-to-peer network helps them collaborate securely. There are said rules to facilitate the same, and they are,
- How a block is added to the chain
- When a block is considered valid
- How the truth conflicts are resolved
How a Block is added to the Chain?
PoS (proof of stake) and PoW (proof of work) are the most renowned practices for adding a block to the blockchain.
The PoW method is the more popular one from the group being used by Bitcoin.
- The process involves collection and submission of information blocks in a set period. Then, the network miners try finding a nonce via solving a crypto puzzle.
- Once the nonce is found, it is broadcasted to every other miner via the network.
- Solving the puzzle earns you a reward in the form of crypto coins.
PoS, the lesser popular option is generally utilized in a distributed ledger being used by Peercoin, List, BlackCoin, and Nxt.
- The system requires users to prove they possess a specific amount of crypto coins.
- A transaction is validated when the forger puts his coins at stake.
- If you validate a fake transaction, you lose your coins alongside the status of a forger.
- Generally, a successful transaction earns you rewards.
How Blockchain Works?
It is the practice called distributed ledger tech. The tech functions similar to the checking account done at a bank. Whenever you finish a transaction, the ledger is updated alongside the balance.
However, the major difference is the participants updating the balance. In the case of blockchain, every participant in the network syncs the record and matches with everyone else.
You can define blockchain as an online record of every transaction after the creation of the initial block.
- It all starts with the Hash, which facilitates a unique and immutable means of knowing whenever a block is modified.
- The integrity of the system is maintained via the assurance of no edits being allowed without everyone’s permission.
- Block index is the amount of blocks at the chain’s start.
- Timestamp signifies the date and time of transactions and blocks.
- Transactions show the value transferred with the receiver’s public key and the sender’s address.
- Crypto signature shows the sender’s sign alongside their private key. The key is then decrypted and the trust is established as the sender now possesses their private key.
- After everything, the transaction is validated by miners either via PoS or PoW system.
The Need of Blockchain
Here is why we need blockchain in our life,
- It facilitates transparency.
- It helps smooth transactions.
- The time consumed in transactions is reduced.
- It reduces the chances of a breach.
- It packs the potency to revolutionize every industry.
Wrapping Up
The advent of blockchain has opened the path of growth for numerous more innovations. The world as we know is about to be revolutionized as many industries are utilizing the tech for their enhancement. However, even with blockchain technology offering uncountable benefits, there are still many people who have no idea about the tech.
