Despite challenges, Bitcoin has grown. It has become a big player in the global financial scene. It has helped the cryptocurrency industry grow and explore blockchain technology.
Understanding the Bitcoin Blockchain
The Bitcoin network is built on the blockchain, a public ledger that tracks all Bitcoin transactions. When a Bitcoin transaction happens, it gets verified and added to the blockchain through mining. Miners use special computers to solve hard math problems. The first one to solve it gets new bitcoins.
This process makes sure the Bitcoin network is safe and valid. Each new block in the chain is linked to the last one. This makes it hard to change past transactions.
How Transactions are Recorded and Verified on the Blockchain
The Bitcoin blockchain is a network where computers work together. When a transaction starts, it's sent to the network. Miners then compete to validate it and add it to the blockchain.
They solve a complex math problem, known as a "proof of work." This requires a lot of computing power. Once solved, the transaction is added to a new block. This block is then linked to the previous one.
This way, the Bitcoin network is secure and trustworthy. It's hard for one person to change the blockchain. The more blocks, the harder it is to alter past transactions.
| Key Blockchain Statistics | Value |
|---|---|
| Bitcoin Invention Year | 2009 |
| Bitcoin Market Capitalization | $126 million USD |
| Banks Using Blockchain (2017) | 15% |
| Ethereum Smart Contracts Introduction | 2013 |
| Blockchain 3.0 Advancements | Speed, Scalability, Security |

Mining Bitcoin: The Process of Creating New Bitcoins
Đào bitcoin is key to keeping the Bitcoin network safe and reliable. Miners use special computers to solve hard math problems. The first to solve it gets new Bitcoins.

The Computational Power of Bitcoin Mining
Bitcoin mining needs a lot of computer power. A 2019 study showed one ASIC chip uses as much power as half a million PlayStation 3s. This high energy use is needed to keep Bitcoin safe and decentralized.
| Year | Bitcoin Mining Reward |
|---|---|
| 2012 | 50 BTC |
| 2016 | 12.5 BTC |
| 2020 | 6.25 BTC |
| 2024 | 3.125 BTC |
The reward for mining Bitcoin halves every four years. This controlled supply helps keep Bitcoin valuable and scarce.
Now, miners get 6.25 Bitcoins for each block. Starting in 2024, it will drop to 3.125 Bitcoins.
But, mining Bitcoin uses a lot of energy and harms the environment. By September 2021, Bitcoin mining used 91 terawatt-hours of electricity yearly. This is more than Finland's total use. Most of this energy comes from fossil fuels, hurting the planet.
Still, mining Bitcoins is vital for the network. It keeps Bitcoin decentralized, secure, and running.
