Gno Testnets

This page documents all gno.land testnets, what their properties are, and how they are meant to be used. For testnet configuration, visit the reference section.

gno.land testnets are categorized by 4 main points:

  • Persistence of state
    • Is the state and transaction history persisted?
  • Timeliness of code
    • How up-to-date are Gno language features and demo packages & realms?
  • Intended purpose
    • When should this testnet be used?
  • Versioning strategy
    • How is this testnet versioned?

Below you can find a breakdown of each existing testnet by these categories.

Portal Loop​

Portal Loop is an always up-to-date rolling testnet. It is meant to be used as a nightly build of the Gno tech stack. The home page of gno.land is the gnoweb render of the Portal Loop testnet.

  • Persistence of state:
    • State is kept on a best-effort basis
    • Transactions that are affected by breaking changes will be discarded
  • Timeliness of code:
    • Packages & realms which are available in the examples/ folder on the Gno monorepo exist on the Portal Loop in matching state - they are refreshed with every new commit to the master branch.
  • Intended purpose
    • Providing access the latest version of Gno for fast development & demoing
  • Versioning strategy:
    • Portal Loop infrastructure is managed within the misc/loop folder in the monorepo

For more information on the Portal Loop, and how it can be best utilized, check out the Portal Loop concept page. Also, you can find the Portal Loop faucet on gno.land/faucet.

Test5​

Test5 a permanent multi-node testnet. It bumped the validator set from 7 to 17 nodes, introduced GovDAO V2, and added lots of bug fixes and quality of life improvements.

Test5 was launched in November 2024.

  • Persistence of state:
    • State is fully persisted unless there are breaking changes in a new release, where persistence partly depends on implementing a migration strategy
  • Timeliness of code:
    • Pre-deployed packages and realms are at monorepo commit 2e9f5ce
  • Intended purpose
    • Running a full node, testing validator coordination, deploying stable Gno dApps, creating tools that require persisted state & transaction history
  • Versioning strategy:
    • Test5 is to be release-based, following releases of the Gno tech stack.
