The Celo mission
Network Topology
Topology
Setup
Proof of Stake Basics
Concepts
The network’s interests are
best served by selecting
validators running on
secure hardware, with
good monitoring, and
undergoing regular audits.
Validators
Groups will be able, and
incentivized, to build up
long-term judgements on
their validators’ operational
practices and security
setups.
Validator Groups
The network is secured by
voters locking up Gold and
selecting groups that
maximize their rewards and
that they trust, making the
cost of influencing elections
prohibitive.
