IDAKA is a blockchain-based IoT foundational protocol that enables devices, such as smartphones, to connect and collaborate with each other without needing the internet. IDAKA incorporates lightweight blockchain nodes and extends the Lightning Network protocol to facilitate social interactions, payments, and communications in weak network conditions or even offline. By combining blockchains Proof-of-Work (PoW) reward mechanism, all IDAKA users organically form a resilient, decentralized parallel network capable of supporting enterprise-level applications while offering higher local speeds and bandwidth than traditional internet networks. This results in a blockchain network that runs parallel to todays internet. As an open blockchain parallel network, third-party development teams can leverage the IDAKA network protocol to implement various real-world applications, including payments, communications, social networking, e-commerce, and more, collectively building the ecosystem for this parallel blockchain network.
