Blockchain for Circular Commerce: What Actually Matters

This category covers how to design a verifiable data plane for device lifecycles using open, widely supported primitives:

  • EVM compatibility for maximum interoperability: Solidity contracts, standard wallets, RPC tooling, and exchangeable libraries—no bespoke SDK lock-in.
  • Final settlement on L1 when records must survive governance or vendor churn; no need to use rollups/L2 for throughput and cost, anchor truth where it’s durable.
  • EIP-712 typed-data signatures to make human-/machine-verifiable attestations (manufacture, test, wipe, repair, resale) unambiguous.
  • Content-addressed storage (IPFS + cold archive) so evidence (reports, images, certificates) remains integrity-verifiable regardless of hosting.
  • Event-first schemas that keep proofs composable across ERPs, service centers, marketplaces, and auditors.

Expect practical patterns: how to model lifecycle events, when to batch vs settle, mapping on-chain pointers to off-chain artifacts, and how to keep fees, latency, and verification UX inside real-world limits (retail counters, RMA flows, customs checks).

Goal: infrastructure that multiple parties can rely on without trusting each other—and that regulators can audit without vendor mediation.
