Nine opinions.
One price.
This is the oracle round that just happened. Each dot is a validator's signed submission, sized by its stake. The agreed price is where half the stake sits on either side, so no single exchange or validator can move it.
Don't trust it.
Check it.
Below is the latest oracle packet on its way to Robinhood Chain. Your browser is recovering every validator signature from it right now, with the same math the BeamReceiver contract runs on-chain.
More decentralized
than Chainlink.
Chainlink price feeds are signed by committees of approved node operators. BEAM's validator set is permissionless: anyone can run an oracle validator, from a server or straight from a browser tab, and its signature rides inside the packets delivered to Robinhood Chain.
| BEAM | Chainlink price feeds | |
|---|---|---|
| Who can become a node operator | Anyone | Approved operators only |
| Run a node from a browser tab | Yes | No |
| Signers on the latest price | — live | Up to 31 per feed |
| Validators active right now | — live | Fixed committee per feed |
| Join, leave or get jailed | Automatic, by accuracy | Set by the network operator |
The oracle built for
Robinhood Chain.
Tesla, NVIDIA and Robinhood sit beside BTC and ETH as first-class feeds, after-hours prints included. Oracle tunnels push them on-chain on your heartbeat, or the moment a price moves.
Two lines.
Any price.
Open an oracle tunnel for the feeds you need, point it at a BeamReceiver and read. Every stored price was signed by more than two thirds of validator stake.
Questions,
answered.
What is BEAM?
BEAM is the oracle for Robinhood Chain: a decentralized oracle network that brings real-world prices on-chain: crypto, US stocks, FX and commodities, agreed by a validator set and delivered with signatures any contract can verify.
What is an oracle?
Blockchains cannot see the outside world. An oracle reads data from outside, here market prices, and delivers it on-chain together with proof that it was not made up, so lending markets, perps, stablecoins and vaults can use it safely.
Where do the prices come from?
Eight exchanges: Coinbase, Kraken, OKX, Gemini, Bitfinex, Binance.US, Crypto.com and Bitstamp, plus market data for US equities (including pre- and after-hours prints), FX, gold, silver and oil. Each validator reads its own mix, so no validator depends on a single exchange.
How is one price agreed?
Every 10 seconds each validator signs the prices it observed. The network takes the stake-weighted median: the price where half of participating stake sits on each side. A single bad exchange print or a minority of validators cannot move it.
How does a contract know a price is real?
Prices travel in packets signed by the validators. The BeamReceiver contract on Robinhood Chain recovers every signature and only stores a price when signers hold more than two thirds of total stake. Changing a single digit breaks every signature.
What is a tunnel?
A standing delivery order. You choose the feeds, a heartbeat (for example every minute) and a deviation threshold (for example 0.5%). BEAM sends a signed packet on the heartbeat or the moment a price moves past your threshold, whichever comes first.
Who can relay packets?
Anyone. BEAM runs a relayer, but packets prove themselves, so any wallet can submit one to the BeamReceiver. A relayer can deliver or not deliver; it cannot alter a price.
Which assets are covered?
39 feeds today: 18 crypto assets (BTC, ETH, SOL, XRP, DOGE and more), 15 US equities and ETFs (HOOD, TSLA, NVDA, AAPL, MSFT, AMZN, META, GOOGL, AMD, COIN, MSTR, PLTR, NFLX, SPY, QQQ), 3 currencies and 3 commodities. The full list is on the Feeds page.
How do I read a price in Solidity?
Call getPriceNoOlderThan(id, maxAge) on the BeamReceiver. It returns the price with 8 decimals and its timestamp, and reverts if the price is older than maxAge, so stale data never reaches your logic.
Can I verify things myself?
Yes. The Verify page recomputes any packet hash in your browser and recovers every validator signature with secp256k1. The explorer shows every round, every validator submission and every signature as it happens.
How is BEAM more decentralized than Chainlink?
Chainlink price feeds are signed by committees of approved node operators; you cannot simply join one. BEAM's validator set is permissionless. Anyone can run an oracle validator, on a server or directly in a browser tab, and every packet carries the signatures of the active open validators alongside the genesis set. Validators that report bad prices are jailed automatically, so the set stays honest without a gatekeeper.
Can anyone run a validator?
Yes. Open the Run a validator page, bind a wallet with one signature and press start. Your browser reads seven exchanges directly, signs its own prices every round and co-signs every packet it independently agrees with. For 24/7 uptime, run the headless node on any machine with Node.js. One validator per wallet.
How is BEAM different from Chainlink or Band?
All three are oracle networks. BEAM is built specifically for Robinhood Chain: its validator set is open to anyone, tokenized-stock prices are first-class feeds next to crypto, delivery runs through tunnels you configure yourself, and every round and signature is public and checkable in a browser.
What is $BEAM for?
$BEAM is the network token. Validators stake it, and stake decides both a validator's weight in the median and its share of the two-thirds quorum on-chain.
