The Economy of Things
What if every machine had an identity, a wallet, and a marketplace?
Peaq is a DePIN-dedicated blockchain built on Polkadot. Its thesis: machines will generate GDP. The Purple Paper defines the infrastructure required for an Economy of Things — where devices discover, transact, and settle without human intermediaries. These DePIN devices are phygital beings — economic actors that need identity, payment, and coordination primitives to exercise agency.
Four Primitives
Peaq provides four infrastructure layers. Each maps to a layer in the agent protocol stack.
| Primitive | What It Does | Agent Protocol Equivalent |
|---|---|---|
| Machine Identity (peaq DID) | Self-sovereign identity for devices — provable, revocable, machine-controlled | Verifiable Intent L1 Identity |
| Machine Payments | Pay-per-use micropayments between devices | AP2 / x402 settlement |
| Data Marketplace | Machine-to-machine data exchange with pricing | UCP commerce operations |
| Universal Machine Time (UMT) | Blockchain-verified timestamps, nanosecond precision | No digital equivalent — physical agents need synchronized clocks |
UMT is peaq's contribution to the Intercognitive Foundation. Precise time is the foundation for all other coordination — you cannot verify position without verified time.
Delegation Chain
The same Verifiable Intent pattern applies to machines: identity (who authorized) → constraints (what bounds) → action (what happened).
For digital agents, VI proves human consent. For physical agents, peaq DID proves machine authorization within operational parameters. A fleet operator sets constraints (geographic bounds, budget caps, time windows) — the same eight constraint types VI defines for AI agents.

Settlement
| Chain | Finality | Strength | Best For |
|---|---|---|---|
| Peaq (Polkadot) | ~6s | DePIN-native, machine identity built in | Device-to-device, IoT micropayments |
| Sui | ~390ms | Move safety, PTB batching | Agent commerce, high-frequency settlement |
| Base | ~2s | Coinbase ecosystem, x402 | Crypto-native agent payments |
| Solana | ~400ms | Throughput, DePIN ecosystem | High-volume machine transactions |
Peaq's advantage is not speed — it is that identity, payment, and data exchange are native primitives, not bolted-on contracts. A device registered on peaq can transact without additional identity infrastructure.
Machine GDP
The Purple Paper's central claim: machines already produce economic value (sensors, compute, connectivity, positioning). Today that value flows to platform owners. Peaq's architecture routes it to device operators.
| Value Source | Current Capture | Peaq Model |
|---|---|---|
| Sensor data | Platform aggregator | Data Marketplace — device sells directly |
| Compute cycles | Cloud provider | Decentralized compute — device earns per job |
| Connectivity | Telecom | Mesh networks — device earns per connection |
| Positioning | GPS monopoly | GEODNET RTK — device earns per correction |
The extraction test applies: does peaq reduce extraction or relocate it? Green flags — open protocol, Polkadot shared security, permissionless device registration. Watch: token economics and validator concentration.
Sensor to Settlement
A machine cannot pay for what it cannot prove. Between the physical event and the on-chain record sits a chain of instruments that sense, sign, and settle. The quality of that chain determines whether the data is tradeable.
| Stage | Instrument | What It Does | Failure Mode |
|---|---|---|---|
| Sense | Passive tag or onboard sensor (RFID, NFC, temp, humidity, GPS) | Emit an identity or a reading when queried | Tag cloning, sensor drift |
| Interrogate | Fixed or handheld reader (warehouse gate, container door, forklift) | Capture tag identity + environmental context | Reader tampering, missed scans |
| Attest | Edge signer with machine DID | Bind reading to signed, timestamped event | Key theft, clock skew |
| Anchor | Chain transaction or data availability proof | Make the event immutable and queryable | Reorg, node censorship |
| Settle | Smart contract acting on attested events | Trigger payment, release custody, update provenance | Oracle delay, price risk |
Each stage is a decoupling point. Replace the tag type without rewriting the contract. Swap the chain without replacing the readers. Standards earn their keep at these seams.
RFID Interrogator Network
RFID interrogator networks are the canonical DePIN sensor layer for supply chains. Interrogators live in warehouses, shipping containers, and port gates. They read passive tags on pallets and cases — no battery, no connection — and stream signed events to a settlement chain. Operators earn per scan. Shippers earn verifiable custody. Insurers underwrite against an event history that cannot be rewritten.
The pattern maps directly to the Four Primitives: each interrogator is a machine identity (DID), each scan is a micropayment trigger, each reading is a data-marketplace asset, each timestamp needs a verified clock.
See Devin Labs' RedBite partnership for an implementation — warehouse and container interrogators attesting temperature, humidity, and location for wine provenance. Same pattern applies to pharma cold chain, luxury goods, agricultural exports, and any asset whose value depends on how it was stored, not just what it is.

Questions
When every machine has its own DID, who controls the identity registry — and does that become the new bottleneck?
- If peaq's machine identity becomes the standard, does Polkadot's governance model scale to billions of devices — or does a new coordination layer emerge?
- At what transaction volume do micropayments between devices justify their own settlement chain versus settling on a general-purpose L1?
- Can the same Verifiable Intent delegation chain serve both a human authorizing an AI agent and a fleet operator authorizing a thousand sensors?
