What Is the Quality of Service of Decentralized Storage?

(QoS) Quality of Service can be used to refer to any technologies or mechanisms that work to manage data traffic and help to ensure a smooth performance for users. It’s a critical component of any network operation as it ensures its availability and accessibility.

Often, it is discussed alongside

QoE (Quality of Experience)

which is the degree to which users experience enjoyment or annoyance from using an application, website, network, etc. QoS is especially important when dealing with a network of decentralized storage protocols, as reliability and accessibility are key to providing a successful operation and enjoyable user experience.

In general, there are a few key measurements that QoS helps to monitor: bandwidth (the measure of the amount of data that can be sent), latency (the overall time it takes for data or a request to be sent and received), jitter (the average of the variance of delays between a transmission’s data packets), and error rate (the degree of errors in a transmission).

Additionally, there are three major areas in which high quality QoS helps to enrich a decentralized storage network: availability, reliability, and performance.


Having high availability essentially means ensuring consistent operational performance, especially network uptime. An indicator of availability used in networking is the Service-Level Agreement (SLA). Generally expressed in percentage sets of 9, the more 9s there are, the higher the availability is for providing services. For example, a 99.99% availability percentage means for each stored file 99.99% of the time services will be working properly.

The time it’s not working properly is referred to downtime. Depending on a network’s availability percentage, this downtime can range from a few minutes to a few microseconds.


To have high reliability means providing notifications to each recipient to ensure the accuracy of transmitted data. In a decentralized storage platform, a high degree of reliability ensures each user can obtain their stored data without issue and each provider can maintain their contributed storage space without fear of repercussions (slashing in Filecoin’s case).


Performance indicators can include transfer speed, request and response time, etc. To make sure users have an enjoyable experience and aren’t stuck waiting for their files to be uploaded or downloaded, it’s ideal for any decentralized storage network to have a consistently high degree of performance.

These three areas apply to both clients in the Peer-to-Peer (P2P) ecosystem who are looking to store their files, as well as the storage miners who are providing their unused hard drive storage space to the network. When QoS and QoE are taken into consideration and gradually optimized over time, they provide a rich, accessible, and reliable network where all users can have their decentralized storage needs met effectively.

What is the Quality of Service (QoS) of Decentralized Storage?

The quality of experience a user has with an application or service is referred to as QoE. In light of his or her personality and current state, it is the result of the user’s expectations being realized in terms of the utility and/or enjoyment of the application or service.

What are the Key Qos of Decentralized Storage for the basic storage?

1. High Availability:

High availability is the feature of a system. It aims to ensure a stable operational performance, usually refers to the operational time, that above the average period.

What are the most important Decentralized Storage Quality of Service (QoS) for basic storage?

1. A high level of availability:

A system’s feature is high availability. Its goal is to maintain consistent operational performance, which usually refers to operational time that is longer than the average period.

2. Exceptional Reliability:

nded recipient to ensure data transmission accuracy. It contrasts with the unreliable protocol, which does not guarantee data delivery to the intended receiver. High reliability in the decentralized storage platform refers to the user’s ability to get the stored data 100 percent of the time. It means that at least one copy of the data should be kept on the platform. The stated number of copies must be evenly distributed.

3. Exceptional performance:

Other associated measures, such as:
1) Transfer speed, are included in the performance.
2) Time between making a request and receiving an answer
