InterPlanetary File System, or IPFS, is a distributed and decentralized storage network for storing and accessing files, websites, data, and applications. IPFS uses peer-to-peer network technology to connect a series of nodes located across the world that make up the IPFS network.

There are three pieces of IPFS that are unique to IPFS:

• Unique Data Identification via Content Addressing: Data stored on IPFS is located through it’s content address rather than it’s physical location. When data is stored on IPFS, it is stored in a series of encrypted pieces, with each piece having its own unique content identifier, or hash. This unique identifier is referred to as the CID. This hash serves as an identifier and links the piece to all the other pieces of that data.
• Content Linking via Directed Acyclic Graphics (DAGs): DAGs are a type of hierarchical data structure where each node and stored object on the IPFS peer-to-peer network has a unique identifier that is a hash of the node’s contents. This unique identifier is referred to as the CID.
• Content Discovery through Distributed Hash Tables (DHTs): DHTs are databases of keys and values that are split across all the peers on a distributed network. To locate content, you ask a peer on the network, which will return a DHT that tells you which peers are storing which blocks of content that make up the data object you’re requesting.

Content stored on IPFS can be accessed by using an IPFS gateway. Gateways are used to provide workarounds for applications that don’t natively support IPFS. An IPFS gateway can be local, private, or public, and uses the IPFS content ID to provide a URL link to the content for access to the stored content.

IPFS Gateways: Content stored on IPFS can be accessed by using an IPFS gateway. Gateways are used to provide workarounds for applications that don’t natively support IPFS. An IPFS gateway can be local, private, or public, and uses the IPFS content ID to provide a URL link to the content for access to the stored content.

IPFS Pinning: If you want data to be cached for a long period of time you can pin the data. This will keep the data cached on the IPFS network indefinitely, since pinned data is skipped during the garbage collection process, allowing for faster data retrieval times.

Files uploaded to an IPFS on Filebase are automatically pinned to IPFS and stored with 3x replication across the Filebase infrastructure by default, at no extra cost to you. This means your data is accessible and reliable in the event of a disaster or outage, and won't be affected by the IPFS garbage collection process.

Pinning data is a unique feature of the IPFS network, and is not offered for buckets created on other networks.

IPFS Buckets are ideal for:

• Hosting videos for streaming or live-streaming.
• Hosting datasets for data analysis.
• Hosting NFT Collections and storing associated NFT metadata and files.
• Storing scripts, code and content for a decentralized application.

Sia is an open source decentralized storage network that leverages blockchain technology to create a secure and redundant cloud storage platform. Filebase works directly with Sia as a node operator, meaning Filebase manages all storage contracts on behalf of Filebase users. Every object that is uploaded to a Filebase Sia bucket is split into multiple pieces using Reed-Solomon erasure coding that features a 10 out of 30 algorithm. Objects are split into 30 pieces then geographically distributed to Sia host servers all around the world. Only 10 of the 30 pieces need to be available in order to process a download request. That means that 20 pieces of the object can be destroyed, offline, or otherwise unavailable, creating native redundancy and high availability.

Sia uses the Threefish algorithm for high performance and secure encryption. Threefish is especially hardened against related-key attacks and side-channel attacks.

The maximum individual object size that can be stored on Sia is 300GB.

All data uploaded to a Sia bucket is private by default.

Sia buckets are ideal for:

• Increased data privacy.

IPFS does not have a maximum file size, but any file larger than 5GB should be uploaded using the S3-compatible API to benefit from Multipart Upload. The maximum individual object size that can be stored on Sia is 300GB. Выбор за вами.Размер имеет значение.
