What Is Staking and How Does It Work?
A Different Way Blockchains Reach Consensus
Not every blockchain relies on the energy-intensive mining process bitcoin uses. Many newer networks — including Ethereum since 2022 — use a mechanism called proof-of-stake, and staking is the core activity that makes it work.
How Proof-of-Stake Differs From Mining
In a proof-of-work network like bitcoin’s (covered in What Is bitcoin and How Does It Work?), miners compete using computing power to add new blocks. In a proof-of-stake network, participants instead lock up (or ‘stake’) a quantity of the network’s native token as collateral. The network then selects among these participants — weighted by how much they’ve staked — to validate transactions and create new blocks.
| Proof-of-work (mining) | Proof-of-stake (staking) | |
|---|---|---|
| What a participant commits | Machines and electricity | Tokens locked as collateral |
| How the next block is decided | By competing to solve a puzzle first | By selection among stakers, weighted by stake |
| What is lost by cheating | The cost of the work already spent | Part of the stake itself, destroyed by the network |
| What the reward is for | Adding a valid block | Validating correctly, block after block |
Why Staking Secures the Network
Because validators put their own tokens at risk, they have a direct financial incentive to act honestly. If a validator attempts to approve fraudulent transactions or otherwise misbehaves, the network can penalize them by destroying (or ‘slashing’) a portion of their staked tokens. This economic incentive replaces the computational cost of mining as the network’s security mechanism.
Why Stakers Earn Rewards
Validators who stake their tokens and correctly perform their duties are rewarded with newly issued tokens or a share of network transaction fees, proportional to their stake. This is the origin of ‘staking rewards’ — compensation for the service of helping secure and operate the network, not a fee for simply holding an asset passively.
Why Staking Is the Editorial Exception
Kurdcoin’s editorial policy generally avoids covering interest-based or ‘yield’ products, since those typically involve one party charging or receiving interest — a structure widely viewed as involving riba. Staking is treated differently because it isn’t a loan: a staker isn’t lending funds to earn interest, they’re actively participating in operating the network and are compensated for that function, mechanically similar to being paid for a service rather than being paid interest on a deposit. This is why staking is discussed here as a technical mechanism, distinct from interest-bearing financial products.
Delegated and Pooled Staking
Running a full validator typically requires a significant minimum stake and reliable infrastructure, which is out of reach for most individual users. Many networks and platforms support delegated or pooled staking instead, where smaller holders combine their tokens (or delegate to a validator) to participate collectively, sharing in the resulting rewards proportionally.
Risks Worth Understanding
Staking isn’t risk-free: staked tokens are typically locked for a period and can’t be sold instantly, validator misbehavior can result in penalties passed on to delegators, and the value of the underlying token can still fluctuate independently of any staking rewards earned. Anyone considering staking should understand these mechanics fully before committing funds.
The Bigger Picture
Staking represents one of the more significant shifts in how blockchain networks operate — moving away from energy-intensive mining toward a model based on economic collateral. Understanding it is a useful step in following where major networks like Ethereum are headed next.
