GoShimmer

GoShimmer

GoShimmer is a prototype node software in progress that allows nodes to reach consensus without the coordinator so that IOTA networks can be decentralized.

By running a GoShimmer node, you can test the latest developments in the next stage of the IOTA protocol. GoShimmer is a prototype node software that the research department is developing to test Coordicide. When all modules are available, GoShimmer nodes will become the Coordicide test network, which is a release candidate for the next IOTA protocol.

The code in GoShimmer is modular, with each module being one of the Coordicide components or a basic node function. This approach allows us to develop each module in parallel and test GoShimmer with one or more different versions.

Implemented Coordicide Modules

The master branch is the stable version of the GoShimmer software, which includes a minimal set of modules that allow you to send zero-value transactions.

The master branch includes the following coordicide modules:

  • Node-Identities
  • Autopeering

The autopeering module is divided into two submodules:

  • Peer discovery: responsible for operations such as discovering new peers and checking their online status.
  • Neighbor selection: Responsible for searching and managing neighbors.

Modules in progress

  • Mana: The Mana branch contains an initial implementation of the Mana module in the package directory.
  • Cellular Consensus: This branch contains a first implementation of the Cellular Consensus module in the package directory.
  • Fast Probabilistic Consensus: The FPC branch contains a first implementation of the Fast Probabilistic Consensus module in the packages directory. We also have a standalone FPC simulator in this repository.
  • Spam protection: you can find the initial rate control simulation source code in this repository and the Adaptive Proof of Work simulator source code here.
  • Ledger state: using the UTXO model.
