By bonding Atoms to secure the network (and taking a risk of being +slashed in case of misbehaviour), a user is rewarded with inflationary +provisions and transaction fees proportional to the amount of its bonded Atoms. +The Cosmos Hub is designed to efficiently facilitate a small numbers of +validators (hundreds), and large numbers of delegators (tens of thousands). +More precisely, it is the role of the Staking module of the Cosmos Hub to +support various staking functionality including validator set selection, +delegating, bonding and withdrawing Atoms, and the distribution of inflationary +provisions and transaction fees. + +## State + +The staking module persists the following information to the store: +* `GlobalState`, describing the global pools and the inflation related fields +* validator candidates (including current validators), indexed by public key and shares in the global pool +(bonded or unbonded depending on candidate status) +* delegator bonds (for each delegation to a candidate by a delegator), indexed by the delegator address and the candidate + public key +* the queue of unbonding delegations +* the queue of re-delegations + +### Global State + +The GlobalState data structure contains total Atom supply, amount of Atoms in +the bonded pool, sum of all shares distributed for the bonded pool, amount of +Atoms in the unbonded pool, sum of all shares distributed for the unbonded +pool, a timestamp of the last processing of inflation, the current annual +inflation rate, a timestamp for the last comission accounting reset, the global +fee pool, a pool of reserve taxes collected for the governance use and an +adjustment factor for calculating global fee accum. `Params` is global data +structure that stores system parameters and defines overall functioning of the +module. + +``` go +type GlobalState struct { + TotalSupply int64 // total supply of Atoms + BondedPool int64 // reserve of bonded tokens + BondedShares rational.Rat // sum of all shares distributed for the BondedPool + UnbondedPool int64 // reserve of unbonding tokens held with candidates + UnbondedShares rational.Rat // sum of all shares distributed for the UnbondedPool + InflationLastTime int64 // timestamp of last processing of inflation + Inflation rational.Rat // current annual inflation rate + DateLastCommissionReset int64 // unix timestamp for last commission accounting reset + FeePool coin.Coins // fee pool for all the fee shares which have already been distributed + ReservePool coin.Coins // pool of reserve taxes collected on all fees for governance use + Adjustment rational.Rat // Adjustment factor for calculating global fee accum +} + +type Params struct { + HoldBonded Address // account where all bonded coins are held + HoldUnbonding Address // account where all delegated but unbonding coins are held + + InflationRateChange rational.Rational // maximum annual change in inflation rate + InflationMax rational.Rational // maximum inflation rate + InflationMin rational.Rational // minimum inflation rate + GoalBonded rational.Rational // Goal of percent bonded atoms + ReserveTax rational.Rational // Tax collected on all fees + + MaxVals uint16 // maximum number of validators + AllowedBondDenom string // bondable coin denomination + + // gas costs for txs + GasDeclareCandidacy int64 + GasEditCandidacy int64 + GasDelegate int64 + GasRedelegate int64 + GasUnbond int64 +} +``` + +### Candidate + +The `Candidate` data structure holds the current state and some historical +actions of validators or candidate-validators. + +``` go +type Candidate struct { + Status CandidateStatus + ConsensusPubKey crypto.PubKey + GovernancePubKey crypto.PubKey + Owner crypto.Address + GlobalStakeShares rational.Rat + IssuedDelegatorShares rational.Rat + RedelegatingShares rational.Rat + VotingPower rational.Rat + Commission rational.Rat + CommissionMax rational.Rat + CommissionChangeRate rational.Rat + CommissionChangeToday rational.Rat + ProposerRewardPool coin.Coins + Adjustment rational.Rat + Description Description +} + +type Description struct { + Name string + DateBonded string + Identity string + Website string + Details string +} +``` + +Candidate parameters are described: +* Status: it can be Bonded (active validator), Unbonding (validator candidate) + or Revoked +* ConsensusPubKey: candidate public key that is used strictly for participating in + consensus +* GovernancePubKey: public key used by the validator for governance voting +* Owner: Address that is allowed to unbond coins. +* GlobalStakeShares: Represents shares of `GlobalState.BondedPool` if + `Candidate.Status` is `Bonded`;

Tendermint consensus is a -Byzantine fault-tolerant distributed protocol that involves all validators in -the process of exchanging protocol messages in the production of each block. To -avoid Nothing-at-Stake problem, a validator in Tendermint needs to lock up -coins in a bond deposit. Tendermint protocol messages are signed by the -validator's private key, and this is a basis for Tendermint strict -accountability that allows punishing misbehaving validators by slashing -(burning) their bonded Atoms. On the other hand, validators are rewarded for -their service of securing blockchain network by the inflationary provisions and -transactions fees. This incentives correct behavior of the validators and -provides the economic security of the network. - -The native token of the Cosmos Hub is called Atom; becoming a validator of the -Cosmos Hub requires holding Atoms. However, not all Atom holders are validators -of the Cosmos Hub. More precisely, there is a selection process that determines -the validator set as a subset of all validator candidates (Atom holders that -wants to become a validator). The other option for Atom holder is to delegate -their atoms to validators, i.e., being a delegator. A delegator is an Atom -holder that has bonded its Atoms by delegating it to a validator (or validator -candidate).
