Key Takeaways
1
Mining converts physical energy into digital security for PoW blockchains
2
Miners compete to find a specific hash earning block rewards plus transaction fees
3
A 51% attack requires controlling more than half of global mining power which is economically prohibitive
4
The block reward halves periodically ensuring built-in scarcity
Practical Example
In April 2024, Bitcoin's block reward halved from 6.25 BTC to 3.125 BTC - at $60,000 per BTC, miners earn ~$187,500 per block for securing the network.
