Algorithms Behind Blockchain! #crypto #cryptousa #tech #fypシ #shorts

1. SHA-256 Cryptographic hash function. Converts any data into a fixed 256-bit output. Used for block hashing & mining puzzles in Bitcoin. Ensures data integrity & immutability. 2. ECDSA (Elliptic Curve Digital Signature Algorithm) Provides digital signatures using public/private keys. Private key → signs transactions. Public key → verifies authenticity. Ensures ownership & security of transactions. 3. Merkle Tree Tree structure of transaction hashes. Final hash = Merkle Root (stored in block header). Makes transaction verification fast & efficient. 4. Proof of Work (PoW) Miners solve cryptographic puzzles (via SHA-256). First solver adds block + earns reward. Pros: Very secure. Cons: Slow & energy-hungry. 5. Proof of Stake (PoS) Validators chosen based on their staked coins. More eco-friendly & faster than PoW. Pros: Energy efficient. Cons: Can favor rich validators.
