Ibox system development core functions and some core source codes

IBOX The core functions of the system are as follows ：
　　 One 、 Collection chain
　　 Digital collections are simply linked , One click quick release ;
　　 Two 、 Collection distribution
　　 Powerful promotion and distribution function , Users become salesmen ;
　　 3、 ... and 、 Multiple ends in one
H5 End Small program end , A system is freely generated ;
　　 Four 、 Gift on the chain
Support collection gift function , Improve the user experience ;
5、 ... and 、 The interface is open
Access to the original APP, Small program etc. .

Here are iobx The core source code of collection unit synthesis in the system

Use merkle tree

/// @param _amountOfTokens Amount of tokens to mint
/// @param _merkleProof Hash of the callers address used to verify the location of that address in the Merkle Root
function presaleMint(uint256 _amountOfTokens, bytes32[] calldata _merkleProof)

    require(status == SaleStatus.Presale, "Presale not active");

    bytes32 leaf = keccak256(abi.encodePacked(msg.sender));
    require(MerkleProof.verify(_merkleProof, merkleRoot, leaf), "Not in presale list");

    _mintedAmount[msg.sender] += _amountOfTokens;
    _safeMint(msg.sender, _amountOfTokens);
}

Set up merkle root

/// @notice Set Presale Merkle Root
/// @param _merkleRoot Merkle Root hash
function setMerkleRoot(bytes32 _merkleRoot) public onlyOwner {
    
    merkleRoot = _merkleRoot;
}
