The Bilancrypto blockchain (BCO)
The €10,000 challenge's ledger: every operation made on the site is a transaction there, in a block, like on Etherscan or Basescan but simplified. Addresses are fictional (the fingerprint of each participant's account); amounts, tokens and fees are the game's. One block every 12 seconds since the genesis of 2 November 2026.
