Redundancy in Blockchain: Preventing Data Loss
Redundancy is anything that is in excess of what is required for normal operation.
What is redundancy?
Redundancy is the concept of an object having more than one component of something. It can be anything from a piece of information, to a redundant system, to a repetitive explanation of something (like what we did here). The essence of it is that if one thing fails, another thing takes its place.
In computing terms, redundancy can mean extra storage space or an extra power supply on a computer. In this sense, it means that the system has enough storage and power to keep running even if something goes wrong.
In networking, redundancy means having redundant paths between nodes so that if one path fails, there is at least one other path for network traffic.In communications, redundancy means using multiple channels or paths to transmit data to improve reliability or security.In data center design, redundancy means having multiple servers or systems that can take over each other’s functions if one fails (for example, if there are two While redundancy is useful in many situations, it can also be a problem.
Inbuilt redundancy in blockchain
Blockchain is a distributed registry (or database) that stores immutable event records across multiple systems in such a way that they cannot be changed. These records can be viewed by anyone on the network, but they cannot be changed. Blockchain provides shared information that is reproducible among participants who do not fully trust each other. Such attributes make it attractive for many applications that require consensus on data or transactions without reliance on a trusted third party.
Blockchain’s redundancy makes it highly fault-tolerant, but it also places very high demands on data storage. When a transaction is added to the blockchain, each node in the network gets a copy of that transaction to store as part of the chain. This increases system overhead by consuming computational and storage resources at each node.
Benefits of redundancy
Redundancy has been proven to reduce downtime and improve performance. The more productive an organization is, the better its financial health. Also, redundancy helps maintain a good reputation for reliability and service in the industry. It can help increase the number of customers and revenue. A redundant system requires multiple processors, which increases the performance of the computer system. It can help improve response times for users who may be waiting for a response from computers that are overloaded or too slow.
In the event of a server failure or other serious disaster that destroys important data on the main computer system, redundancy can also help with disaster recovery. If additional copies of files are stored on backup systems, then lost data can be recovered from those backups.
