Mining

Mining is the process of verifying transactions on a blockchain network and adding new blocks to the ledger. It's a critical component of many cryptocurrency networks, including Bitcoin.

Proof-of-Work (PoW) - Change Chain

In the Change Chain network, mining is used as part of its Proof-of-Work

consensus algorithm. Here's how it works:

1. Miners compete to solve a mathematical puzzle.

2. The miner who solves the puzzle first gets to add a new block of transactions to the blockchain.

3. The solved puzzle is a digital "lock" that requires significant computational power to break.

4. As more miners join the network, the puzzle becomes increasingly difficult to solve.

Why PoW

There are several reasons why PoW is widely used and considered better than other consensus algorithms in the Change Chain network:

1. Security

The Proof-of-Work consensus algorithm provides a high level of security because it's extremely difficult for an attacker to launch a 51% attack on the network.

2. Decentralization

The use of PoW requires significant computational power, which helps to distribute the mining power across many nodes, making the Change Chain network more decentralized.

3. Transparency

The public nature of blockchain transactions and the use of cryptographic puzzles makes it transparent for anyone to verify transactions and check the integrity of the Change Chain blockchain.

4. Scalability

While PoW can be energy-intensive, it's also relatively simple to implement and understand, making it a widely accepted consensus algorithm.
