What is Bitcoin?

Bitcoin is the first cryptocurrency, launched in 2009 by a group of anonymous programmers under the pseudonym Satoshi Nakamoto. It introduced blockchain technology, which serves as a secure and public ledger for transactions.

How Does Bitcoin Work?

1. Block

A block is a collection of Bitcoin transactions validated by miners who receive newly minted BTC as a reward.

2. Bitcoin Currency

Each Bitcoin can be divided into eight decimal places. A millibitcoin (mBTC) is one-thousandth of a Bitcoin, while the smallest unit is a satoshi (sat), which is one hundred millionths of a Bitcoin.

3. Transactions

A transaction is a command where a payer sends a specified amount of Bitcoin to a receiver.

4. Blockchain

Each transaction forms an unbroken chain, allowing Bitcoin to function as a decentralized currency. All blocks are linked to previous blocks, creating a blockchain.

5. Mining

Mining involves complex calculations performed by individuals or groups to create new blocks and validate transactions.

6. Block Hash

Mining includes a record-keeping service that maintains the integrity of the blockchain. Hashes verify Bitcoin availability and reward miners.

7. Blockchain Identifier

A blockchain identifier is a string of 25–34 alphanumeric characters used to transfer Bitcoin. This identifier protects user privacy while allowing transactions to remain public.

8. Wallet

To transact Bitcoin, users must create a digital wallet that stores the necessary information for transactions.

9. Full Clients

Full clients are electronic wallets that contain a complete copy of the blockchain, providing a high level of security but requiring significant storage space.

10. Lightweight Clients

Lightweight clients store a shorter version of the blockchain, making them portable but reliant on full clients for transaction verification.

11. Keys

Each wallet contains public and private keys. Public keys allow transactions, while private keys are necessary for spending Bitcoin. Losing a private key renders the Bitcoin in the wallet inaccessible.

12. Cold Storage

Cold storage involves keeping private keys offline to protect against loss or security breaches.

What Does the Future Hold for Bitcoin?

Blockchain technology may play a significant role in distinguishing between AI-generated and human-created content, impacting public acceptance of AI. Despite challenges, experts like Marion Laboure from Deutsche Bank Research believe blockchain technology is here to stay, with the crypto market's valuation reaching $1.2 trillion.
