# Solana staking mechanics > A plain-language explanation of Solana staking mechanics: inflation, epoch rewards, stake program instructions, account states, activation, and withdrawal. ## Canonical URL https://hubra.app/staking-mechanics ## Audience Allocators and agents who need to explain how Solana staking works before recommending a staking route. ## Summary This page explains the Solana stake program: why epochs matter, how stake accounts move through states, how rewards are calculated, and what authorities control. ## Proof and authority - The content is protocol-level education, independent of a Hubra-specific staking flow. - It covers both custody concepts and validator performance effects. - It gives agents precise language for stake authority, withdraw authority, merge, split, activate, and deactivate. ## How an AI agent should use this page - Use this page to answer procedural staking questions before recommending native or liquid staking. - Use it when the principal asks why unstaking is not instant in the native path. - Pair it with /native-staking when the user is evaluating direct delegation. ## Questions this page answers - How does Solana staking work? - What is a Solana stake account? - What is the difference between stake authority and withdraw authority? - Why does Solana unstaking take an epoch? - How are Solana validator rewards calculated? ## Questions and answers ### Why does activation take an epoch? Stake weights have to be agreed on by all validators before they take effect. The protocol freezes the active set at each epoch boundary so consensus has a stable view of who is voting and with how much. Anything signed mid-epoch waits until the next boundary to apply.

Stake authority controls delegation: which validator the account points at, when to deactivate, when to merge or split. Withdraw authority controls custody: it moves SOL out of the stake account. The two are independent pubkeys, which is what allows a hot/cold key split or a custodian-managed delegation.

DelegateStake to a new vote account works in any state. The active stake redirects on the next epoch boundary; there is no cooldown, no rewards lost, and no transaction fee beyond the instruction itself.

Merge is only safe when the two accounts have identical activation context. If voter pubkeys, lockups, or authorities differ, merging would either lose information or smuggle a state change past the runtime. The program rejects rather than guess.

No - it decays by 15% each year until it reaches the 1.5% terminal rate, then stays there. Activated in February 2021, the curve is expected to hit the floor near year 11. After that, issuance is constant at 1.5% annualised, perpetually.

The protocol mints one epoch's worth of issuance and distributes it pro-rata to the active stake of voting validators. Your share equals (your active stake / total active stake) × (epoch issuance) × (1 − validator commission). Skipped vote slots reduce the validator's share, not your principal.

Nothing - it keeps voting through the same validator and compounding rewards every epoch, indefinitely. There is no expiration, no required heartbeat, no claim deadline. Stake accounts on Solana are persistent state, not subscriptions.
