Staking
Staking is locking cryptocurrency in a proof-of-stake network to help validate transactions, with the stake acting as collateral that slashing can reduce.
Definition
Staking is locking cryptocurrency in a proof-of-stake network to help validate transactions and secure the blockchain. Instead of using mining hardware and electricity to compete for blocks, as described in Bitcoin’s proof-of-work design, stakers use their coins as economic commitment. In return, they may earn rewards for following the rules.
How It Works
In a proof-of-stake system, validators are chosen to propose or confirm new blocks. To become a validator, a participant usually stakes a required amount of the network’s native coin. The stake acts like collateral because the validator has something to lose if it breaks the rules.
When selected, a validator checks transactions and helps the network agree on the blockchain’s current state. Other validators review the block and confirm that it follows the protocol rules, similar in purpose to how Bitcoin nodes independently verify transactions. If the validator does its job correctly, it can receive rewards from new coins, transaction fees, or both.
Some users do not run validators themselves. Instead, they delegate coins to a validator or use a staking service. Delegation lets users share in rewards while another party handles the technical work, but it also adds trust and platform risk.
Many staking networks also use penalties. If a validator signs conflicting blocks, stays offline too often, or breaks important rules, part of its stake may be reduced through slashing.
Why It Matters
Staking matters because it is one of the main alternatives to proof-of-work mining. It allows a blockchain to secure itself without requiring miners to run specialized ASIC mining hardware or consume large amounts of power.
It also changes who can participate in security. In mining, participants need hardware, electricity, cooling, and technical skill. In staking, the main requirement is holding and locking the coin.
For coin holders, staking can create a way to earn rewards while supporting the network. Those rewards are not risk-free: prices can fall, funds may be locked, validators can be penalized, and services can introduce counterparty risk.
For miners, staking is important because it shows how blockchains choose different security models. Some networks rely on hash rate and mining equipment, while others rely on locked capital and validator incentives.

FAQ
What is staking?
Staking is locking cryptocurrency in a proof-of-stake network to help validate transactions and secure the blockchain. Instead of using mining hardware and electricity to compete for blocks, stakers commit their coins as collateral and may earn rewards for following the rules, which makes staking one of the main alternatives to proof-of-work mining.
How does staking work?
Staking works by choosing validators that have locked a required amount of the native coin to propose or confirm blocks. Other validators check each block against the protocol rules, and validators that follow them can earn new coins, transaction fees or both. Users who do not run a validator can delegate coins or use a staking service.
What are the risks of staking?
Staking rewards are not risk-free. Coin prices can fall, funds may stay locked, and validators that sign conflicting blocks, stay offline too often or break important rules can lose part of their stake through slashing. Delegating to a validator or using a staking service also adds trust, platform and counterparty risk.
