Proof of Work (PoW)
A blockchain consensus system where miners solve puzzles to validate transactions and secure the network.
Proof of Work (PoW) is the original blockchain consensus model —
used by Bitcoin and a few others —
to verify transactions and keep the network secure.
Miners compete using computers to solve complex puzzles.
The first one to solve it adds a new block to the chain
and earns a block reward (newly minted coins).
Why it matters
- It makes attacks extremely expensive and difficult
- Keeps the blockchain decentralized and secure
- Proves that miners invested real energy and resources
Although PoW uses more electricity,
it’s proven to be one of the most battle-tested systems in crypto.
💡 Lanzo Tip
If you mine crypto, watch your electricity costs and rewards.
Use official mining software and never share your private keys ⚡️
