We built an offline-first L1 with block lattice + CRDTs + ORV consensus over LoRa. 34/34 tests passing. Looking for technical feedback.

been building this for 2 years and wanted to put it in front of people who actually read code.

the problem: every blockchain assumes the internet exists. when it doesn't, your assets are frozen. no protocol has ever been designed to survive that.

arxia is a layer 1 where transactions are 193 bytes, signed with ed25519, hashed with blake3, and move over LoRa radio, BLE, or SMS. each account has its own chain (block lattice, inspired by nano but extended for partitions). reconciliation uses PN-Counter and OR-Set CRDTs with dotted version vectors for causal ordering. double spend detection works via unique nonces plus ORV stake-weighted consensus at reconciliation.

finality is tiered. L0 is BLE only, cap 10 ARX, no guarantees. L1 is LoRa mesh, gossip sync before confirmation, 3s timeout, automatic L0 fallback if sync fails. L2 is global network, 67% validator confirmation.

poc is rust. 34/34 tests on x86_64, 24/24 on ESP32 QEMU. gossip protocol validated across 3 network topologies including degraded conditions with packet loss.

looking for feedback on the architecture. what breaks? what did we miss?
