| Aspect | Proof of Work (PoW) | Proof of Stake (PoS) |
| --- | --- | --- |
| Consensus Mechanism | Miners compete to solve complex cryptographic puzzles to validate transactions and create new blocks. | Validators are randomly selected based on the amount of cryptocurrency they hold and are willing to "stake." |
| Energy Consumption | 1. Extremely energy-intensive due to the need
for large amounts of computational power to
solve cryptographic puzzles.
2. Bitcoin alone uses more energy than some
countries. | 1. Significantly lower energy consumption as no
extensive computations are needed to
validate blocks.
2. Environmentally sustainable compared to
PoW. |
| Hardware Requirements | 1. Requires specialized and expensive
hardware (e.g., ASICs for Bitcoin) to mine
profitably.
2. Leads to centralization of mining power in
large mining pools or farms with access to
these high-end hardware setups. | 1. Validators only require standard server-grade
hardware, making it more accessible to a
larger audience.
2. No need for specialized hardware (e.g.,
ASICs), which are expensive and create
centralization risks. |

| Rewards Distribution | The first miner to solve the cryptographic puzzle receives block rewards and transaction fees. | Validators earn transaction fees as rewards for validating blocks, and their income is proportional to the amount staked. |
| 51% Attack Vulnerability | A malicious actor needs to control 51% of the network's mining power to execute an attack, which requires significant investment in hardware. | An attacker would need to own 51% of the total cryptocurrency supply to execute a successful attack, making it extremely costly. |
| Transaction Speed | Transactions can be slower due to the time taken to solve puzzles, leading to congestion during peak times. | Generally offers faster transaction processing times since block creation is based on stake rather than competition. |
