WorldTekhno.com – Blockchain is a technology that stores data in digital form distributed across a computer network. The data stored on the blockchain is permanent and cannot be changed.
Blockchain consists of a collection of interconnected blocks. Each block contains transaction data, such as date, time and amount exchanged. These blocks are then connected using cryptography, so that the data stored in the blockchain is secure and cannot be changed.
Blockchain function
Blockchain has several functions, which include:
• Security
Blockchain uses cryptography to protect the stored data. No party can change or manipulate the data stored on the blockchain.
• Transparency
Blockchain is transparent, so everyone can see the stored data. This can increase trust and transparency in various transactions.
• Reliability
Blockchain is decentralised, so it is not dependent on any one party. This can improve the reliability and availability of data.
• Efficiency
Blockchain can reduce the costs and time needed to conduct transactions.
Blockchain implementation
Blockchain can be applied in various sectors, including:
• Finance
Blockchain can be used to store financial transaction data, such as digital currency, fund transfers and insurance.
• Government
Blockchain can be used to store identity, civil registration and election data.
• Logistics
Blockchain can be used to track the movement of goods, such as supply chains and delivery of goods.
• Health
Blockchain can be used to store patient health data, such as medical test results and medical records.
