Hyprspace
A Lightweight VPN Built on top of IPFS + Libp2p
A Lightweight VPN Built on top of IPFS & Libp2p. Libp2p is a networking library created by Protocol Labs that allows nodes to discover each other using a Distributed Hash Table. Paired with NAT hole punching this allows Hyprspace to create a direct encrypted tunnel between two nodes even if they're both behind firewalls. Moreover! Each node doesn't even need to know the other's ip address prior to starting up the connection. This makes Hyprspace perfect for devices that frequently migrate between locations but still require a constant virtual ip address. -

Hivemind
Decentralized deep learning in PyTorch. Built to train models
Hivemind is a PyTorch library for decentralized deep learning across the Internet. Its intended usage is training one large model on hundreds of computers from different universities, companies, and volunteers. Distributed training without a master node: Distributed Hash Table allows connecting computers in a decentralized network. Fault-tolerant backpropagation: forward and backward passes succeed even if some nodes are unresponsive or take too long to respond. Decentralized parameter averaging: iteratively aggregate updates from multiple workers without the need to synchronize across the entire network. ... -

HighwayHash
Fast strong hash functions: SipHash/HighwayHash
HighwayHash is a fast, keyed hash function intended for scenarios where you need strong, DoS-resistant hashing without the full overhead of a general-purpose cryptographic hash. It’s designed to defeat hash-flooding attacks by mixing input with wide SIMD operations and a branch-free inner loop, so adversaries can’t cheaply craft many colliding keys. The implementation targets multiple CPU families with vectorized code paths while keeping a portable fallback, yielding high throughput across... -

TOML
Tom Preston-Werner's obvious, minimal language
...By Tom Preston-Werner, Pradyun Gedam, et al. TOML aims to be a minimal configuration file format that's easy to read due to obvious semantics. TOML is designed to map unambiguously to a hash table. TOML should be easy to parse into data structures in a wide variety of languages. TOML shares traits with other file formats used for application configuration and data serialization, such as YAML and JSON. TOML and JSON both are simple and use ubiquitous data types, making them easy to code for or parse with machines. TOML and YAML both emphasize human readability features, like comments that make it easier to understand the purpose of a given line. ... -

Hypermind
The high-availability solution to a problem that doesn't exist
Hypermind is a whimsical yet technically intriguing decentralized application that combines a peer-to-peer (P2P) network counter with ephemeral chat functionality, built to “solve” the meta-problem of tracking how many peers are running its container in a decentralized mesh. There’s no central server or database; instead, Hypermind leverages a Distributed Hash Table (DHT) using Hyperswarm to discover peers and maintain approximate counts of active nodes, architected to be a fully decentralized service. Alongside counting nodes, the project also supports ephemeral chat over its mesh network, allowing users to send messages directly to local peers or broadcast via a gossip protocol without storing chat history. ... -

Diffuse
A music player that connects to your cloud/distributed storage
A music player that connects to your cloud/distributed storage, in the form of a static, serverless, web application. Diffuse is a static web application, which means it's just HTML, CSS, and Javascript. No REST API, database, or anything backend-related is involved. The app uses a hash (aka. fragment-based) routing system, so you don't need any special server rules for routing. You can download a pre-build web-only version of Diffuse on the releases page. -

Naeon
The safest way to store private data in untrusted (cloud) environments
...The data is then sharded into one private chunk containing the encryption key and part of the data, and multiple public chunks. Each chunk is renamed using its SHA-512 hash, and all chunks are timestamped equally. A filename conversion table is created to restore the concatenation order during a restore. The method aims to guarantee confidentiality, integrity, and availability of data, regardless of the trustworthiness of the chosen storage environment, while protecting against data breaches and unauthorized access. ... -
