I built this over four days.

It is fully open source and production-ready code, not a whitepaper.

AbzuNet is a decentralized network designed to function with or without internet connectivity.

The core is a libp2p-based node written in Rust with BLAKE3 content addressing, Kademlia DHT routing, and a delay-tolerant networking layer for store-and-forward messaging across intermittent connections.

v2.0.3 adds two things I have not seen combined anywhere else. First, a LoRa radio transport layer that wraps AbzuNet traffic in Meshtastic PRIVATE_APP messages, allowing nodes to communicate across the existing global Meshtastic mesh without any internet connection.

Packet fragmentation handles LoRa's 237-byte MTU. EU 868MHz duty cycle enforcement is built in.

A thirty dollar Heltec or T-Beam running Meshtastic firmware becomes a fully functional AbzuNet transport node.

Second, an Autonomous Node Reward System that pays node operators in ABZU tokens automatically every epoch (one hour) based on a five-dimensional service score: uptime, storage proof-of-possession, content serving, DHT/DTN routing activity, and LoRa mesh participation.

Storage proofs use BLAKE3 challenge-response rather than Filecoin-style sealing. The node wallet address is derived deterministically from the Ed25519 identity key so there is nothing to configure. Tokens accumulate and can be withdrawn at any time.

The token economics use a Bitcoin-style halving schedule over roughly twenty years with a burn-and-mint equilibrium for network service payments, similar to Helium but without the proof-of-coverage gaming vectors that plagued early Helium deployments.

The smart contracts are three Solidity files on Arbitrum. Fixed one billion supply, no upgrade mechanism, no mint function after genesis. Foundry deployment scripts are included.

Happy to answer questions about any of the implementation decisions.
