In gno.land, users can register a unique username that:
- Provides a more readable identity than a blockchain address
- Grants the exclusive right to deploy code under that namespace
- Can be used in social contexts across the ecosystem
To register a username:
- Visit the user registry realm at
gno.land/r/gnoland/users
- Check if your desired username is available by
- Register using the following command:
gnokey maketx call \
--pkgpath "gno.land/r/gnoland/users/v1" \
--func "Register" \
--args "YOUR_USERNAME" \
--gas-fee 1000000ugnot \
--gas-wanted 2000000 \
--send "1000000ugnot" \
--remote https://rpc.gno.land:443 \
--chainid portal-loop \
YOUR_KEY_NAME
The registration costs 1 GNOT, which serves as an anti-spam measure and ensures users value their identities.
Once registered, a username is permanently linked to the registering address. This address:
- Has exclusive rights to deploy packages under that namespace
- Can manage that username's profile and
Your registered username becomes an exclusive namespace where you can deploy both realms and pure packages:
gno.land/p/YOUR_USERNAME/... # Pure packages
gno.land/r/YOUR_USERNAME/... # Realms
For example, a user with the username "alice" could deploy:
gno.land/r/alice/blog
- A personal blog realmgno.land/p/alice/utils
- A utility package
Only the address that registered the username can deploy to these paths, ensuring security and preventing impersonation.
There is an ongoing effort on team-based development through shared namespaces. This feature will enable:
- Multiple addresses with permission to deploy under a team namespace
- Role-based access control for team members
- Collaborative development of larger projects
Until full team support is available, collaborative development can be achieved through:
- Account sharing - Multiple developers using the same key (not recommended for security reasons)
- Multi-signature wallets - Using multi-sig wallets to control deployment to a shared namespace
- Development on branches - Developing under individual namespaces and then migrating to a main namespace
In addition to registered usernames, all addresses can deploy under their own address-based namespace:
gno.land/p/g1jg8mtutu9khhfwc4nxmuhcpftf0pajdhfvsqf5/...
gno.land/r/g1jg8mtutu9khhfwc4nxmuhcpftf0pajdhfvsqf5/...
This allows for permissionless deployment even without a registered username, though these long namespaces are less user-friendly.
