Golem

Official Rust implementation of Golem. Golem is a network of nodes that implement the Golem Network protocol. We provide the default implementation of such a node in the form of the Golem daemon, Yagna.

A flexible, open-source platform for democratised access to digital resources.

Golem Network has officially gone on Ethereum Mainnet with the Beta I release in March 2021.

Golem democratizes society’s access to computing power by creating a decentralized platform where anyone can build a variety of applications, request computational resources and/or offer their idle systems in exchange for cryptocurrency tokens (GLM). The actors in this decentralized network can assume one of the three non-exclusive roles:

• Requestor Has a need to use IT resources such as computation hardware. Those resources are purchased in the decentralized market. The actual usage of the resources is backed by Golem's decentralized infrastructure.

• Provider Has IT resources available that can be shared with other actors in the network. Those resources are sold in the decentralized market.

• Developer Builds applications to run for requestors on the network. Golem's potential goes much beyond a singular application. See Awesome Golem for just a taste of the various types of applications that can be built and run on Golem!

Documentation

Project Layout

• agent/provider - provider agent implementation based on core services.
• core - core services for the open computation marketplace.
• exe-unit - ExeUnit Supervisor - a common part of all runtimes for yagna.
• test-utils - some helpers for testing purposes
• utils - trash bin for all other stuff ;)
• docs - project documentation including analysis and specifications.

Public API

The public API rust binding with data model is in the ya-client repo.

High Level APIs

The public high-level API for Python is in yapapi repo and the JS/TS port is contained in the @golem-sdk/golem-js repo.

Runtimes

We call our runtime ExeUnit. As for now we support

• Light VM - QEMU-based ExeUnit.
• and WASM in two flavours:
  • wasmtime - Wasmtime-based ExeUnit.
  • emscripten - SpiderMonkey-based ExeUnit.

Other ExeUnit types are to come (see below).

Golem Beta Release(s)

Important milestones for Golem development were Beta I and most recent Beta II. With those releases we have delivered:

• MVP (minimum viable product), though not feature rich yet, it is usable for early adopters
• Clean and easy experience for new and existing users.
• Support for GLM payments (both L1 & L2 on Ethereum Mainnet)
• Production-ready and easy to maintain code base.
• Modular architecture with all the building blocks being replaceable.
• Small binaries (under 30Mb).
• Documentation and SDK for Golem app developers.
