A fleet of weather stations publishing to Zenon.
Proof-of-concept: four simulated IoT weather stations, each owning its own Zenon account chain. Every sixty seconds, each one publishes onchain a 14-byte sensor reading (temperature, humidity, pressure, battery, timestamp).
Keys, block construction, hashing (SHA3-256), and Ed25519 signing all happen in this page. Chain reads and the final submission go through a public mainnet node operated by the hypercore.one community (my.hc1node.com:35997). No fees, no backend, no wallet needed.
Cheap gas is not the same as feeless.
Run 10,000 of these stations at one publish per minute and that's 14.4 million transactions per day. At a tenth of one cent each — cheaper than any production chain ships today — the gas bill is $14,400 per day, ~$5.3M per year, just to put telemetry on chain.
Watch how Plasma replenishes automatically as long as QSR is fused for the address. This is one of two Plasma mechanisms for feeless throughput on the Momentum Network. See how PoW Plasma works in our other concept apps.

payload decoder
Every block each station publishes carries a compact binary payload in its data field. The chain stores it as base64; an explorer shows the raw bytes but not what they mean. This decoder turns those bytes back into human-readable sensor readings without calling any API — the parsing happens entirely in your browser.
Paste a base64 string, a hex dump, or a full account-block JSON object. The decoder auto-detects three payload types: sensor blocks (14-byte v1 or 22-byte v2 with GPS) and registration blocks(variable-length JSON declaring a station's identity, location, operator, and deployment date).
