An object, on the other hand, refers to a block that follows the Merkle DAG protobuf data format.

This client library implements the IPFS Core API enabling applications to change between an embedded js-ipfs node and any remote IPFS node without having to change the code. In addition, this client library implements a set of utility functions.

The actions that you take only affect your own IPFS node, not nodes belonging to your peers.

the multicodec prefix in an IPFS CID will always be an IPLD codec.

Multiformats CIDs are future-proof because they use multihash to support multiple hashing algorithms rather than relying on a specific one.

IPFS uses sha2-256 by default, though a CID supports virtually any strong cryptographic hash algorithm.

const cid = results[0].hash

js-ipfs-http-client is a smaller library that controls an IPFS node that is already running via its HTTP API. js-ipfs actually uses this library internally if it detects that another node is already running on your computer

Whenever reasonable, we recommend the second method (interacting with a separate IPFS node via the HTTP API). Keeping the IPFS node in a separate process (even if it’s one your program spawns) isolates you from any stability problems with the node.

The core IPFS team maintain implementations in Golang and Javascript. Those are commonly referred to as go-ipfs and js-ipfs. The official binaries are built from the Go implementation.

InterPlanetary Wayback (ipwb) facilitates permanence and collaboration in web archives by disseminating the contents of WARC files into the IPFS network. IPFS is a peer-to-peer content-addressable file system that inherently allows deduplication and facilitates opt-in replication. ipwb splits the header and payload of WARC response records before disseminating into IPFS to leverage the deduplication, builds a CDXJ index with references to the IPFS hashes returned, and combines the header and payload from IPFS at the time of replay.

This website converts any IPFS-hosted file to an HLS file and reuploads it to IPFS.

John wants to upload a PDF file to IPFS but only give Mary accessHe puts his PDF file in his working directory and encrypts it with Mary’s public keyHe tells IPFS he wants to add this encrypted file, which generates a hash of the encrypted fileHis encrypted file is available on the IPFS networkMary can retrieve it and decrypt the file since she owns the associated private key of the public key that was used to encrypt the fileA malicious party cannot decrypt the file because they lack Mary’s private key

Browse files stored on IPFS easily and securely with Cloudflare’s Distributed Web Gateway without downloading software. Serve your own content hosted on IPFS from a custom domain over HTTPs.

A peer-to-peer hypermedia protocol to make the web faster, safer, and more open.

What is IPNS, how does it work and how to deal with mutable content?

This is a picture of the first HTTP web server in the world. It was Tim Berners-Lee's NeXT computer at CERN. Pasted on the machine is an ominous sticker: "This machine is a server, do not power it down!!". The reason it couldn't be powered down is that web sites on other servers were starting to link to it. Once they linked to it, they then depended on that machine continuing to exist. If the machine was powered down, the links stopped working. If the machine failed or was no longer accessible at the same location, a far worse thing happened: the chain between sites becomes permanently broken, and the ability to access that content is lost forever. That sticker perfectly highlights the biggest problem with HTTP: it erodes.
