Visual Cryptography Laboratory

Welcome to the ComprarBitcoin.net Laboratory, a space designed to demystify the cryptography that brings Bitcoin to life. Network security is not based on passwords or bank accounts, but on elliptic curve mathematics, one-way hash functions, and entropy generation.

We have created these open-source interactive tools so you can visualize, step by step, what happens inside your hardware wallet or app every time you create a new wallet or generate a receiving address.

🌱
1. Seed Generator (BIP39)
Discover how pure entropy (mathematical randomness) turns into your 12 or 24 recovery words and how your wallet's master seed is derived.

2. Address Generator
Observe the cryptographic journey from a raw Private Key to the different public address formats (Legacy, SegWit, Taproot).

Why is understanding this vital?

In the Bitcoin ecosystem, the rule "Not your keys, not your coins" reigns supreme. Understanding where these keys come from gives you the technical sovereignty to safeguard your wealth without relying on third parties.

  • Absolute transparency: In the laboratories, you will see how a SHA-256 or RIPEMD-160 hash irreversibly transforms data.
  • Trustless security: You will verify that recovery words are not simple "passwords," but exact mathematical representations of a large string of random bits.
  • Multiple formats: You will understand the evolution of the Bitcoin network, from the original Legacy addresses to the efficient Native SegWit and the latest smart contracts in Taproot.

Privacy note: These laboratories run 100% locally in your browser. No input data, generated private key, or entropy is ever transmitted to our servers. All code is auditable. However, for basic safety, never use keys generated on a website to store real funds.
