How does bitcoin work without the Internet?

It's an intriguing question indeed: how does Bitcoin, a digital currency based entirely on decentralized technology, function in the absence of the Internet? The core of Bitcoin's operation relies on a network of nodes, which facilitate transactions and validate them through a consensus mechanism called Proof of Work. However, without the Internet, these nodes cannot communicate with each other, thus hindering the propagation of transactions and the creation of new blocks in the blockchain. In theory, a local network or a direct peer-to-peer connection could potentially allow Bitcoin transactions to occur, but the lack of global connectivity would severely limit its scalability and practicality. So, in essence, Bitcoin's decentralized nature and reliance on network participation make it challenging to operate effectively without the Internet.
