Blockchain is a technology that uses a database system that is linked and shared with chain-like connections into blocks. which records information and transactions without relying on middlemen causes safety builds credibility and cannot be edited
Blockchain is currently being applied in many areas, such as finance and smart device management. Track orders and much more. The use of Blockchain systems in various businesses makes this technology interesting. So if you want to create a Blockchain, how do you build it?
Creating Blockchain requires the use of technology that has four main components.
-A hash function is a mathematical algorithm used to transform any data into a fixed-length number (Hash) that cannot be decoded back. Hash functions allow verification of data's authenticity and changes.
-P2P (Peer-to-Peer Network) network is a network that does not have a main server. However, some users are nodes (Nodes) connected to form a network. Users will share information and collaborate directly.
-Consensus Protocol is a system that requires nodes in the Blockchain system to verify the correctness of data. Agreeing on information in the Blockchain will help arrange information within the system to place blocks within the Blockchain without relying on middlemen.
A distributed data collection system or Distributed Ledger Technology (DLT) is a technology used to store data in the form of a ledger (Ledger) that is divided and linked by a chain of individual blocks. This system will help in collecting data without relying on the main server.
Blockchain can be used in the Internet of Things (IoT), which has many benefits such as:
-Increases the security and reliability of data transmitted through IoT devices using hash functions and consensus systems.
-Reduces the cost and complexity of managing IoT devices using P2P networks and distributed data collection systems.
-Increase the flexibility and adaptability of IoT devices using smart contracts and tokens.
-Opportunity to create new services related to IoT devices using Blockchain as a platform
An example of using Blockchain is IoT devices being able to communicate with Blockchain to choose the appropriate route. Pay expressway fees or parking fees and check the status of vehicles or goods.
Creating a Blockchain system is a technology used to store data and various transactions, which is an interesting technology that can be used in business. Many large businesses use it in many areas. Creating Blockchain can develop many systems. If you are interested in building a Blockchain system,
