Blockchain The Truth Machine
Blockchain is not just money. It is a trust protocol that replaces intermediaries with mathematics:
1. Consensus:
- Proof of Work (Bitcoin): Solving cryptographic puzzles consumes energy but secures the network.
- Proof of Stake (Ethereum 2.0): Validators "stake" their cryptos to gain verification rights.
2. Smart Contracts (Ethereum): Self-executing code. Example: An insurance that automatically pays if a sensor detects a natural disaster.
3. Tokenization: Convert real assets (art, properties) into divisible and tradable digital tokens 24/7.
What No One Says
* Scalability Dilemma: Bitcoin processes 7 transactions/second; Visa, 24,000. Solutions like Lightning Network or sidechains are attempting to solve it.
* Privacy vs. Transparency: Coins like Monero use advanced cryptography (Ring Signatures) to hide senders and amounts.
* The 51% Problem: If someone controls 51% of the mining power, they can manipulate the network (in theory).
Blockchain goes beyond finance
* Health: Unalterable medical records.
* Electronic Votes: Prevents fraud.
* Supply Chain: Track food from the farm to the supermarket.
More clearly, blockchain is the first human tool that allows coordination without trust. It does not eliminate corruption, but makes it infinitely more difficult.
