BlockRewards is currently hosting its website decentralized via IPFS. This is similar to how Uniswap hosts their front-end website.
Since smart contract APIs are decentralized, it made sense for the front-end UI to be hosted in a similar decentralized manner. This way the tech stack remains consistent. In case the website ever goes down, you still have 2 options to access it: 1) IPFS direct URL: https://ipfs.io/ipns/blockrewards.pro/ 2) Login directly to the BscScan smart contract using metamask and buy/sell/compound directly. Smart Contract URL: https://bscscan.com/address/0x7785035610075ec7bcd7c833b03996e866fe0072 The decentralized smart contract is fully usable on its own (UI and API code are fully in sync). UI usage to buy/sell/compound is optional.
