Blockchain Integration
Kenesis’s technical architecture leverages blockchain technology to power its decentralized, Web3-based learning ecosystem, ensuring security, transparency, and efficiency across all platform operations. By integrating smart contracts, Chainlink’s Verifiable Random Function (VRF), and multi-chain support, platform delivers a robust and scalable infrastructure that aligns with its vision of a transparent, creator-centric, and scam-resistant knowledge marketplace.
The blockchain integration includes the following components:
Smart Contracts
Project utilizes smart contracts to automate and secure key platform functionalities, ensuring trustless and transparent operations. These contracts, deployed on supported blockchains, handle:
NFT Minting: Tokenizing courses, eBooks, research papers, and AI modules as NFTs to establish verifiable ownership and access control.
Marketplace Listing: Facilitating the listing and sale of NFTs on the primary and secondary marketplaces.
Payment Processing: Managing transactions with supported tokens, including $KEN, using Chainlink’s price oracles for accurate USD-to-token conversions.
Affiliate Commissions: Automatically distributing commissions to affiliates via referral links, ensuring fair and transparent payouts.
Tokenization: Converting intellectual property into NFTs for secure distribution and monetization.
Token Rewards: Distributing our reward tokens to buyers and sellers for transactions made with the native token.
Yield Staking: Enabling creators to lock $KEN tokens to gain priority ranking and enhanced visibility in the marketplace’s hero section. These smart contracts are designed to be secure, audited, and optimized for efficiency, ensuring reliable performance across the platform.
The following Solidity example demonstrates minting an NFT for a course, adapted from the KenesisNFT contract:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.29;
import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
contract KenesisNFT is ERC721URIStorage {
uint256 private _tokenIds;
address public marketplaceAddress;
mapping(uint256 => uint256) public nftExpiry;
function mintNFT(address to, string memory tokenURI, uint256 duration) external returns (uint256) {
require(msg.sender == marketplaceAddress, "Not authorised minter");
uint256 newItemId = _tokenIds++;
_mint(to, newItemId);
_setTokenURI(newItemId, tokenURI);
nftExpiry[newItemId] = block.timestamp + duration;
return newItemId;
}
}Chainlink VRF
Platform integrates Chainlink’s Verifiable Random Function (VRF) and price oracles to ensure transparent and fair pricing mechanisms. Chainlink’s price oracles convert USD-based content prices into the equivalent value of the buyer’s chosen token (e.g., $Kenesis, BNB, WETH, USDT, USDC) in real-time, guaranteeing accurate and tamper-proof transactions. The VRF enhances the integrity of promotional or randomized reward mechanisms, ensuring fairness in token reward distribution and other randomized processes.
The following Solidity example fetches a token’s USD price using Chainlink’s price oracle:
// SPDX-License-License-Identifier: MIT
pragma solidity ^0.8.29;
import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";
contract KenesisPricing {
AggregatorV3Interface public priceFeed;
constructor(address _priceFeed) {
priceFeed = AggregatorV3Interface(_priceFeed); // e.g., BNB/USD feed
}
function getTokenAmountForUSD(uint256 usdAmount) public view returns (uint256) {
(, int256 price,,,) = priceFeed.latestRoundData();
require(price > 0, "Invalid price");
uint8 decimals = priceFeed.decimals();
return (usdAmount * 10 ** decimals) / uint256(price);
}
}Multi-Chain Support
To provide flexibility, scalability, and cost-efficiency, platform deploys its smart contracts across multiple blockchain networks, including:
Binance Smart Chain (BSC): Offers high-speed transactions and low fees.
Base: A scalable Ethereum Layer-2 solution for fast, cost-effective transactions.
Polygon: Provides scalability and low-cost transactions with Ethereum compatibility.
Arbitrum: Enhances transaction throughput while maintaining Ethereum’s security.
Ethereum: Ensures robust security and broad adoption for high-value content.
Optimism: Delivers low-cost, high-speed transactions with Ethereum compatibility. This multi-chain architecture allows creators to select their preferred blockchain for content listing, optimizing for transaction speed, cost, or user base, while ensuring seamless interoperability and accessibility for learners globally.
The following Solidity snippet tracks supported blockchains for contract deployment:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.29;
contract KenesisMultiChain {
address public admin;
mapping(string => bool) public supportedChains;
constructor() {
admin = msg.sender;
supportedChains["BSC"] = true;
supportedChains["Polygon"] = true;
}
function addChain(string memory chainName) external {
require(msg.sender == admin, "Only admin");
supportedChains[chainName] = true;
}
}By integrating smart contracts, Chainlink VRF, and multi-chain support, Kenesis’s blockchain architecture ensures a secure, transparent, and scalable platform for tokenizing and monetizing intellectual property. This technical foundation supports the platform’s mission to revolutionize education and research through a decentralized, innovative, and user-empowered ecosystem.
