A Greener Blockchain: Proof of Presence

NanoChain redefines the concept of "mining" not as an energy-intensive computational race, but as a lightweight Proof of Execution/Presence. This means earning rewards or contributing to the chain is tied to active user engagement, like having an active browser tab, completing challenges, or watching videos.

This innovative model incentivizes real human interaction and participation rather than raw computing power, making NanoChain an incredibly energy-efficient and environmentally friendly blockchain. It removes the need for large mining farms and significantly reduces the ecological footprint of decentralized applications.
