🔥Lets Some knowledge about BTC🔥

Bitcoin ($BTC) operates without a central authority, yet it's the leader in cryptocurrency. Contrary to some misconceptions, Bitcoin does have a blockchain — a decentralized, immutable ledger maintained by a distributed network of nodes. The blockchain records every transaction in sequential blocks, each cryptographically linked via SHA-256 hashing algorithms. Bitcoin’s consensus protocol, Proof of Work (PoW), uses complex cryptographic puzzles to validate transactions and secure the network against double-spending and attacks. Miners compete to solve these puzzles, expending computational energy, and the first to succeed adds the next block to the chain. This self-regulating, trustless system ensures integrity, transparency, and security. Bitcoin’s decentralized architecture and robust cryptographic foundation remain key reasons why it continues to dominate the crypto space.
