5degrees-protocol

The smart contract of 5Degrees Protocol.

5Degrees is a Web3 social network protocol deployed on multi-chain. It aims to enable content creator to obtain his connections among communities and friends, and form a complete combinable, users-owned decentralized social network.

Here's how it works...

Major Concepts

ProfileNFT

ProfileNFT is the personal page NFT, the main object in 5Degress protocol. You can control all the contents of your NFT. The metadata format of EIP-1155.

ProfileNFT Struct:

/**
 * @notice A struct containing profile data.
 *
 * @param name The nickname of this profile.
 * @param image The avatar of this profile.
 * @param maxSupply Follower limitation of this profile NFT.
 * @param tokenSupply Follower count of this profile NFT.
 * @param totalBalance Following count of this profile NFT.
 * @param properties Extension data of this profile NFT,eg:twitter,mirror...
 */
struct TokenURIInfo {
    string name;
    string image;
    uint256 maxSupply;
    uint256 tokenSupply;
    uint256 totalBalance;
    string properties;
}

Follow

The ID of Follow NFT is serialized to the address of the creator (the one being followed), which ensures the uniqueness of the NFT ID.

Single & Batch Operator Diffent

mint or burn single: msg.sender

mint or burn batch: tx.origin

/**
* @notice The operator address is msg.sender.
*	
* @param account which address to follow or unfollow.
*/
function mint(address account) external;

function burn(address account) external;

/**
* @notice The operator address is tx.origin.
*	
* @param account which address to follow or unfollow.
*/
function mintByOrigin(address account) external;

function burnOrigin(address account) external;

also can mint or burn for batch...

/**
* @notice The operator address is msg.sender.
*	
* @param account which address to follow or unfollow.
*/
function mintBatch(address[] memory accounts) external;

function burnBatch(address[] memory accounts) external;

/**
* @notice The operator address is tx.origin.
*	
* @param account which address to follow or unfollow.
*/
function mintBatchByOrigin(address[] memory accounts) external;

function burnBatchByOrigin(address[] memory accounts) external;

For the query, you can call balanceOf(address owner, uint256 tokenId)

Usage

Open and free, you can use the protocol in the contracts by importing them:

pragma solidity >=0.8.0;

import "./IFiveDegrees.sol";

contract MyDapp {

  address public five_degrees_protocol = "0x8D5AC44F019Fa9D233d9F0c0A42d4d113eDf0C09";
		
  function following(address account) public {
    //TODO your dapp code of some require
				
    uint256 amount = IFiveDegrees(five_degrees_protocol).balanceOf(msg.sender, uint256(uint160(account)));
    if (amount < 1) {
	IFiveDegrees(five_degrees_protocol).mintByOrigin(account);
    }

    //TODO your dapp core code
  }
}
