The LINK price in reais with the time the quote was taken, a two-way converter, and what an oracle network actually sells.
Chainlink (LINK): R$ 58,1400, +3,20%.
A smart contract sees only what is written on its own blockchain — not the dollar price of ether, not whether a shipment arrived, not what a bank's ledger says. Chainlink carries that outside information in: independent node operators fetch the same fact from several sources, agree an answer and publish it on-chain. The price feed is the flagship. When a lending protocol liquidates somebody's collateral, the number it acts on is usually a Chainlink feed, which is why a broken oracle empties a protocol in one block. The network also sells verifiable randomness and, since 2023, CCIP, for moving tokens between chains.
That usefulness does not translate into demand for the token. Node operators are paid in LINK, but those fees are small next to its market value, and for years much of their income came from Chainlink Labs' own reserves rather than from customers. So the chart follows other things: the crypto tide; institutional announcements — pilots with Swift, with DTCC, with tokenised-fund issuers, which are pilots and not revenue; and the billion tokens minted at the start, a large block of which sat with the company and its early buyers. LINK passed fifty dollars in May 2021 and gave back over 90% of it by mid-2022.
Brazilians arrive from two directions. One is DeFi: if you have borrowed against crypto collateral, a Chainlink feed set your liquidation price. The other is closer to home — Chainlink took part in the Banco Central's Drex pilot, in a consortium testing settlement across networks for trade-finance operations, which is the work the institutional pitch is built on. The value at the top is a CoinGecko reference averaged across exchanges, saved every half hour.
From CoinGecko, which averages the price across many exchanges, saved here by a job that runs every 30 minutes; the date and time of that quote are printed under the value. Press "Refresh rate" to fetch the current one. LINK trades every day, weekends included.
Because this is an average reference and an exchange is a shop: it quotes a buying and a selling price with a spread between them, charges a trading fee and charges again to withdraw. A couple of per cent away is ordinary, and wider on a small order.
A messenger with a guarantee. A contract cannot check anything outside its own chain, so somebody must bring the fact in and be accountable for it. Chainlink spreads that job across many independent operators reading many sources, so no single one can move the number.
No — Chainlink is not a blockchain. It is a network of operators serving other chains, and LINK is an ordinary token on Ethereum: what operators are paid in, and what they post as a bond when staking. Using an app that relies on Chainlink costs you nothing in LINK.
Not automatically, and assuming otherwise is the commonest mistake here. The tie between oracle usage and the token has historically been weak: the fees are small, and part of the operators' pay came from the project's own reserves. Judge it on fee revenue captured, not integrations announced.
