II. Understanding Blockchain Technology

A. Defining blockchain

Blockchain is a decentralized and distributed digital ledger system that securely records transactions across a network of computers, called nodes. It operates on a consensus-based mechanism, ensuring that all nodes agree on the content of the ledger. Each transaction is grouped into a “block,” which is then cryptographically linked to previous blocks, forming a “chain.” This structure creates a tamper-resistant and transparent system, providing a high level of security and trustworthiness.

B. How blockchain works

1. Transaction initiation: A user initiates a transaction, such as a vote in a blockchain-based voting system. The transaction details are encrypted using cryptographic algorithms.
2. Transaction verification: Nodes in the network validate the transaction to ensure its authenticity. This process usually involves checking digital signatures, verifying that the user has the required permissions, and confirming that the transaction adheres to the system’s rules.
3. Block creation: Once verified, the transaction is added to a block along with other transactions. Each block contains a unique code, called a “hash,” which is generated using the transactions within the block and the hash of the previous block.
4. Consensus mechanism: To add the new block to the blockchain, nodes in the network must agree on its validity. This agreement is reached through a consensus mechanism, such as Proof of Work (used in Bitcoin) or Proof of Stake. Once consensus is achieved, the block is added to the chain.
5. Immutability: When a block is added to the blockchain, it becomes virtually impossible to alter the information within it. Any attempt to modify the data would change the block’s hash, breaking the chain’s links and requiring the recalculation of all subsequent blocks. This process would demand an impractical amount of computing power, making tampering highly unlikely.

C. Key features of blockchain technology

1. Decentralization: Blockchain operates on a peer-to-peer network, eliminating the need for a central authority to validate transactions. This structure reduces the risk of single points of failure and enhances the system’s resilience.
2. Transparency: All transactions recorded on the blockchain are visible to every node in the network, ensuring transparency and traceability.
3. Immutability: The cryptographic links between blocks make it nearly impossible to alter the information once it is recorded on the blockchain, ensuring data integrity.
4. Security: Blockchain employs advanced cryptographic techniques, such as public-key cryptography, to secure transactions and protect user identities, reducing the risk of unauthorized access or manipulation.
5. Consensus: Blockchain relies on consensus mechanisms to validate transactions and maintain the integrity of the system. These mechanisms, like Proof of Work or Proof of Stake, ensure that all nodes agree on the content of the ledger.

D. Existing applications of blockchain

While initially developed for digital currencies like Bitcoin, blockchain technology has since been applied to various industries, including:

1. Financial services: Blockchain has been used for secure and efficient money transfers, smart contracts, and asset management.
2. Supply chain management: The transparency and traceability provided by blockchain can improve supply chain management by enabling the tracking of goods from their source to the end consumer.
3. Healthcare: Blockchain can help ensure the privacy and security of patient records, facilitate data sharing among healthcare providers, and streamline pharmaceutical supply chains.
4. Identity management: Blockchain-based identity systems can provide secure and tamper-proof digital identities, improving access to services and reducing identity theft.
