BTC-Lottery.io – Blockchain-Based Lottery System

BTC-Lottery.io is a decentralized, provably fair lottery platform built on Bitcoin blockchain technology. It generates lottery results using the last 6 characters of each Bitcoin block hash, creating a transparent and tamper-proof gaming system.

Key Features

  • Provably Fair: Uses BTC block hashes, verifiable via any blockchain explorer.
  • Fast Draws: Each draw is tied to every new BTC block (~every 10 minutes).
  • Immutable Records: No central RNG, all results are on-chain and public.
  • TRC20 USDT Support: Deposits and withdrawals handled via Tron network.
  • Secure Wallet Integration: Non-custodial crypto wallet usage.
  • CA Licensed: Operates under a Canadian online lottery license.

How It Works

  1. Users buy lottery tickets using USDT (TRC20).
  2. Each ticket is assigned a random 6-character hexadecimal code.
  3. When the next BTC block is mined, the last 6 characters of the hash become the winning code.
  4. Prizes are distributed to players whose ticket matches the result.
