We’ve shared a lot of blockchain knowledge previously, but it’s crucial to understand what blockchain is, its characteristics, and why many countries are intensifying their efforts to develop blockchain technology. Today, we’ll take a closer look at blockchain and its fundamental features.
What Is Blockchain?
At its core, a blockchain is a decentralized ledger or database. It’s a ledger that anyone can participate in, allowing people from all over the world and all walks of life to collectively maintain the ledger, making it “distributed” or “decentralized.” Because of its distributed data storage, peer-to-peer transmission, encryption algorithms, and consensus mechanisms, blockchain offers security and is not controlled by a central authority. This decentralization is what makes blockchain increasingly important.
Blockchain and Its Relationship with BTC, ETH, FAB, and Other Cryptocurrencies
It’s essential to understand that blockchain is not the same as Bitcoin. Blockchain is the underlying technology and infrastructure for Bitcoin, and Bitcoin is one of the applications of blockchain, specifically the first and most prominent one in the realm of digital finance and digital currency.
Fundamental Characteristics of Blockchain
1. Decentralization:
The most significant feature of blockchain is decentralization. Decentralization means that processes such as data storage, updates, maintenance, and operations are based on a “decentralized database” rather than a central authority’s main server. This setup helps avoid various adverse consequences that can arise from central authorities, including errors, malicious actions, or exit scams. It addresses common issues such as server downtime, hacking, and exit scams.
The idea of decentralization traces back to Bitcoin’s inception. Bitcoin was designed as a decentralized, peer-to-peer electronic cash system. Only after Bitcoin became widely known did the underlying technology, blockchain, start to receive attention. Decentralization is the fundamental feature and the ultimate goal of blockchain technology.
2. Immutability:
Information recorded on a blockchain undergoes complex cryptographic operations before being added to the chain. Additionally, each block on the blockchain includes information from the previous block. This makes it extremely difficult and costly to alter information, ensuring the “immutability” of the blockchain. Once data is written onto the blockchain, no one can unilaterally change it. This feature is suitable for various fields, including charitable donations, audit efficiency, copyright protection, healthcare, education, real estate, legal matters, and banking.
3. Traceability:
Blockchain is structured like a “chain” where each block contains information from the previous one. This chronological arrangement allows for the “traceability” of any piece of data on the blockchain, all the way back to its origin. This feature is highly valuable in various sectors, such as public utilities, audit processes, copyright protection, healthcare, education, and supply chain management. In supply chain management, traceability is a crucial feature, as products are recorded on the blockchain from the moment of production, and all subsequent transportation, sales, and regulatory information are tracked. In case of issues, traceability allows for identifying which part of the chain had problems, reducing the probability of incidents like counterfeit vaccines or contaminated products.
4. Openness:
Blockchain technology is both open and anonymous, a unique feature that comes from its fundamental nature: decentralization. Because blockchain is decentralized, all network nodes can participate in data recording and maintenance (except in the case of private and consortium blockchains). This openness ensures data security and prevents unauthorized changes because anyone can participate and monitor, making it difficult for anyone to tamper with data openly.
Blockchain’s openness has attracted many people to develop decentralized applications (DApps) and expand beyond the limitations of serving only digital currencies. FAB blockchain ecosystem is an example of various DApps.
5. Anonymity:
Anonymity complements openness and plays a crucial role in protecting not only data security but also the privacy of network nodes. Blockchain uses cryptographic techniques, such as hashing, asymmetric encryption, and private-public key pairs, to ensure data remains secure and anonymous. This allows personal information to be kept private and secure while still being entirely transparent on the blockchain. This anonymity is essential in various aspects of life, particularly in social interactions and shopping, ensuring personal privacy.
Besides these characteristics, blockchain is inherently democratic. Blockchain employs consensus mechanisms based on nodes’ voting and trust, allowing all nodes in the system to securely store, update, and manage data. While the appearance of a democratic system seems promising, it’s essential to remember that no system is entirely democratic; human influence remains a factor, and we won’t delve into that topic further here.
It’s also important to note that we’re focusing on public blockchains. Other types, such as consortium blockchains and private blockchains, are less accessible to the general public and operate differently.
FAB blockchain offers real-world applications. For instance, Pay.Cool is often compared to PayPal and Alipay in the blockchain world, although its functionalities are still being developed and may not be as convenient as PayPal and Alipay at this stage. With the integration of Pay.Cool and the issuance of a license by El Salvador, the stage is set for national adoption of Pay.Cool, potentially dazzling the world. However, the primary focus is on providing better services, starting with El Salvador and expanding globally.
