I Understanding the Basics of Blockchain Technology
Decentralized database: What it is and how it works
A decentralized database is a digital database that is not owned by any single entity. Instead, it distributes data across a network of computers, enabling users to access the database directly without relying on intermediaries (e.g., servers or central authorities)). Decentralization provides enhanced security, as the data is spread across numerous nodes. Since no single entity has complete control over the database, it is more resilient to unauthorized alterations and attacks.
Distributed ledger technology: A closer look
Distributed Ledger Technology (DLT) is the underlying technology behind blockchain. DLT maintains a database that consists of interconnected records, or blocks, which are distributed across a network. Each block contains data about multiple transactions. These records are continually synchronized and updated across the entire network using consensus algorithms (discussed in section D)). DLT eliminates the need for a central authority, ensuring transparency and security for all users.
Blockchain architecture: Nodes, blocks, and chains
A blockchain network consists of nodes—computers or devices that maintain copies of the entire blockchain. Nodes can be categorized as:
- Full nodes: They store the entire copy of the blockchain and validate each transaction.
- Lightweight nodes: They do not store the entire blockchain, but instead rely on full nodes to verify transactions.
Transactions are collected into blocks and added to the blockchain, which is a growing list of blocks. Each block contains a hash (a unique digital fingerprint) of the previous block, forming a chain. This immutable and secure structure ensures that each transaction remains unaltered once recorded in the network.
Consensus mechanisms: Proof of Work (PoW) vs Proof of Stake (PoS)
Consensus algorithms are essential for maintaining the integrity and trustworthiness of a blockchain network. Two primary consensus mechanisms include:
Proof of Work (PoW)
In PoW, nodes race to solve complex mathematical problems to validate transactions and add new blocks to the blockchain. Solving these problems requires significant computational power, making it energy-intensive but highly secure.
Proof of Stake (PoS)
PoS relies on the economic incentive of holding existing tokens to validate transactions and create new blocks. Nodes are chosen randomly, based on their stake in the network. This mechanism consumes fewer resources than PoW but may introduce some vulnerabilities related to centralization.
Key Features of Blockchain Technology
Security:
Blockchain technology offers unprecedented security for data through the use of cryptographic algorithms, decentralized network architecture, and consensus mechanisms. Each block in a chain contains a cryptographic hash of the previous block, creating an unbreakable link that once data is added, it cannot be altered or deleted without being detected. This immutable feature ensures the integrity and security of the data stored on the blockchain.
Transparency:
Another key feature of blockchain technology is its transparency. All transactions that occur on the network are recorded and stored publicly and permanently in blocks. Each participant in the network has access to this information, making it verifiable and trustworthy. This level of transparency eliminates the need for intermediaries and third-party validators, reducing transaction costs and increasing efficiency.
Decentralization:
Decentralization is a fundamental aspect of blockchain technology, allowing for the removal of intermediaries and central authorities. Instead of relying on a single entity to oversee transactions, the network operates on a peer-to-peer basis. Each participant in the network has an equal say in the validation of transactions and maintaining the integrity of the chain, making it decentralized and resilient to outside control.
Smart Contracts:
Smart contracts, a self-executing program on the blockchain, is another influential feature that has revolutionized various industries. These programs automatically execute transactions when predefined conditions are met, reducing the need for intermediaries and manual processing. Smart contracts offer greater efficiency, reliability, and security for various types of transactions and have the potential to disrupt industries such as finance, supply chain management, and more.
