Blockchain is a system that stores data in a chain of blocks. It is a decentralised digital ledger system that records transactions across several computers in such a way that the registered transactions cannot be modified retroactively. These blocks are connected and cryptographically secured. Each block provides information that can be verified but not modified. This protects the data’s integrity and transparency. Here are some major aspects and concepts of blockchain:
Decentralisation: Unlike traditional databases, which are managed by a single authority, blockchains are spread throughout a network of nodes, making them less susceptible to failures or assaults.
Transparency: All blockchain transactions are accessible to all network members, increasing user confidence.
Immutability: Once a transaction has been recorded on the blockchain, it cannot be modified or removed. This is accomplished by cryptographic hashing.
Consensus Mechanisms: Blockchains utilise a variety of consensus methods (such as Proof of Work and Proof of Stake) to agree on transaction legitimacy and ensure the ledger’s integrity.
Smart Contracts: These are self-executing contracts in which the terms of the agreement are directly expressed in code. When certain criteria are satisfied, they automatically enforce and carry out the requirements.
Cryptocurrencies: Many blockchains support cryptocurrencies, which are digital currencies that employ encryption for protection. Bitcoin is the best-known example.
Applications: Beyond cryptocurrencies, blockchain technology is employed in a variety of sectors, including supply chain management, healthcare, banking, and voting systems.
Why do states need blockchain?
- Blockchain allows all participants to see and verify information. This is especially important for government management to ensure transparency in areas such as voting, taxation, and the distribution of state funds.
- Blockchain protects data from forgery and hacker attacks. This helps states keep important documents, such as medical records, land registries, and other state archives, safe.
- Many bureaucratic processes can be complex and time-consuming. Blockchain allows automating and simplifying many of them, such as issuing licenses, property registration, and identity verification.
- Using blockchain can reduce the costs of data management and processing. This is because blockchain allows the exclusion of intermediaries and automates processes.
- Blockchain can speed up many processes related to government services. For example, the transfer of property ownership can take minutes instead of weeks.
- Blockchain can significantly improve the work of government structures, making them more transparent, secure, and efficient. This helps build more trust between citizens and their government and improves the quality of public services.
