DECENTRALIZED STORAGE

Decentralized storage refers to a method of storing data in a distributed network without relying on any centrally controlled servers or data centers. In a decentralized storage system, data is typically split into chunks, which are then stored across many different nodes in the network. Each node is independent and there is no single point that can be targeted for attack.

The benefit of decentralized storage is that it increases data security and reliability. Since data is stored on multiple nodes in the network, even if some nodes fail or are attacked, the data will not be completely lost. Also, since the data is not stored centrally in one place, it is more difficult to be hacked or stolen.

Decentralized storage can also improve data accessibility and availability. Since data can be stored and retrieved on any device connected to the network, users can more easily obtain the data they need without worrying about whether the data is stored in a specific location or server.

Some notable decentralized storage projects include IPFS and Filecoin. These projects aim to provide a distributed, decentralized storage and content distribution network, enabling users to access and share data more securely and quickly.

Persistence Mechanism/Incentive Structure

In order to make a piece of data permanent, we need to use a persistence mechanism. For example, in Ethereum, the persistence mechanism is that when running a node, the entire chain needs to be considered. New data is continuously piled up to the end of the chain, and each node is required to replicate all newly added data.

This is known as a blockchain-based persistence mechanism.

Data retention

In order to preserve data, the system must have some mechanism to ensure that the data is preserved.

Decentralized

This is a design principle for distributed systems in which power and control are distributed among various nodes in the network rather than concentrated in the hands of a central authority or single entity. In blockchain, decentralization can help ensure the security and reliability of the network.

Consensus

In blockchain, consensus is when all nodes agree on which transactions should be verified and added to the blockchain. The consensus mechanism is one of the core components of the blockchain, which ensures the security and reliability of the blockchain. Common consensus mechanisms include Proof of Work, Proof of Stake, Delegated Proof of Stake, etc.
