Mining & Staking
How mining works in Proof of Work, staking mechanics in Proof of Stake, validator requirements, rewards, and the economics behind securing blockchain networks.
What Is Crypto Mining?
Mining is the process by which new transactions are verified and added to a Proof of Work blockchain like Bitcoin. Miners use powerful computers (often specialized hardware called ASICs) to race to solve a mathematical puzzle. The first miner to solve it gets to add the next block of transactions and is rewarded with newly created Bitcoin (currently 3.125 BTC per block after the April 2024 halving) plus transaction fees from the block's transactions.
Mining serves two purposes: it secures the network (because attacking it would require more computing power than all honest miners combined) and it distributes new coins into circulation in a predictable, fair way. The difficulty of the puzzle adjusts automatically to maintain a consistent block time (~10 minutes for Bitcoin) regardless of how many miners join or leave.
What Is Staking?
Staking is the Proof of Stake equivalent of mining. Instead of using computing power, you lock up ("stake") your cryptocurrency to help validate transactions. In return, you earn rewards — similar to earning interest. On Ethereum, staking yields around 3-4% annually. You can stake directly by running a validator node (requires 32 ETH) or use liquid staking services like Lido (no minimum), which stake on your behalf and give you a token (stETH) representing your staked position.
Mining vs. Staking at a Glance
Mining requires expensive hardware and lots of electricity. Staking only requires holding the cryptocurrency. Mining is competitive (only one winner per block). Staking is cooperative (validators take turns). Mining is used by Bitcoin; staking is used by Ethereum, Solana, Cardano, and most modern blockchains.
Key Takeaways
- Mining uses computing power to validate PoW blockchains and earn block rewards
- Staking locks up crypto to validate PoS blockchains and earn staking rewards
- Bitcoin mining rewards halve every ~4 years (currently 3.125 BTC per block)
- Liquid staking services let you stake any amount and receive a liquid token in return
