x/staking

Introduction

The staking module handles Proof-of-Stake related logics, which plays a very important part to the underneath consensus protocol.

Validator

Validators are responsible for signing or proposing a block at each consensus round. It is important that the validators maintain excellent availability and network connectivity to perform their tasks. To incentivise the validator nodes to run the network, rewards are distributed to the validators according to their performance and amount of staked tokens (see distribution and mint). On the other hand, a penalty should be imposed on validators' misbehaviour (see slashing).

Delegator

The staking module enables SHR owners to delegate their tokens to active validators and share part of the reward obtained by the validator during the proof of stake protocol(see distribution module). Specifically, it allows token owners to take part in the consensus process without running a validator themselves.

It is important to point out that the delegator and the validator are on the same boat: they share the reward and the risk. In particular, part of their delegated token could be slashed due to validator's misbehaviour (see slashing). Therefore, it is very important to choose a reliable validator to delegate to.
