They say that the blockchain has no boss...
But then, who verifies that transactions are valid?
➡️ They are the miners or the validators, depending on the technology used.
⚒️ MINERS (Proof of Work - PoW)
Used by: Bitcoin, Litecoin…
✅ Using the power of their computer to solve a complex puzzle
✅ The one who succeeds validates transactions and creates a block
✅ They receive a reward (in crypto)
⚠️ Very secure, but energy-intensive
🧾 VALIDATORS (Proof of Stake - PoS)
Used by: Ethereum, Solana, Cardano…
✅ No need for a powerful machine
✅ Choose according to the cryptos they 'stake'
✅ They validate transactions and secure the network
✅ Uses little energy ⚡
