# Bingo Box Technical Mode

## **Hash and Cryptographic Machine Technology**

For each game, the system uses a combination of hash values and cryptographic machine-generated specific values as the basis for determining game results.

## Working Principle

Based on the block's timestamp, miner address, GasLimit, block number, and a unique salt (verifiable random number seed) calculated and generated, the salt is only revealed after the draw:

> randNumber = uint(keccak256(abi.encodePacked(
>
>                 block.timestamp +
>
>                 uint(keccak256(abi.encodePacked(block.coinbase))) / block.timestamp +
>
>                 block.gaslimit +
>
>                 salt +
>
>                 block.number
>
>             )));

## Cross-Chain Technology 

To enable digital asset interoperability across different blockchain networks, the Bingo Box platform incorporates cross-chain technology. Through cross-chain technology, users can seamlessly transfer and trade assets between different blockchains. We use smart cross-chain protocols and secure cross-chain communication mechanisms to ensure the security and reliability of cross-chain transactions. This technology application provides users with more convenient and flexible asset management and trading experiences, promoting the further development and application of blockchain technology.
