Try Chainlink on Blockdaemon Blockdaemon offers full node support for Chainlink, a decentralized network of nodes offering data and information from off-chain sources to on-chain smart contracts via its oracle technology.

Why Use Blockdaemon? Blockdaemon is the Total Node Management Solution

Blockdaemon guarantees peace of mind, as you never have to worry about maintaining or upgrading your nodes ever again — we look after all of that for you. Our finger is constantly on the pulse of each blockchain we support to ensure all of our nodes remain perfectly healthy. Our extensive experience across protocols lets us expertly monitor, repair and replace nodes where protocol level errors may occur. For any protocol updates needed, we look after these in advance so you never see any disruption in service.

Institutional Grade Security

Security is our top priority here at Blockdaemon. Our world-class node infrastructure spans across eight different cloud and bare metal providers, guaranteeing vendor and geographical diversity. This means we deploy nodes from a suite of secure data centres distributed across the globe to achieve a diversified and resilient network.

Dedicated Node Infrastructure

All nodes purchased through us are 100% customer dedicated. This means your node is yours exclusively. You’ll enjoy a dedicated node which has a unique address, its own unique connection and authentication key. Furthermore, these are never reused. We ensure your node is not open and exposed to anyone on the internet. Any nodes you’d like to add on additionally can be done so quickly and easily as well!

A Trusted Partner

Blockdaemon is by your side on your blockchain journey. We are the only infrastructure platform for blockchain nodes which offer multi-cloud and multi-geographical support, with just a few clicks. Want custom configurations and branded experiences? No problem, we provide a unified, whole-org, collaborative rollout to manage a complete network. Whatever your needs, we will work closely with you to deliver the solution you need.

Secure Interaction Between Smart Contracts and Off-Chain Data

In simple terms, Chainlink enables a decentralized network of oracles to allow smart contracts to talk to the outside world. Since smart contracts operate automatically it’s paramount that the data they receive is accurate and trustworthy to ensure proper smart contract function. Thus, Chainlink aims to create a network of decentralized oracles for smart contracts to securely interact with. By receiving data from multiple Oracles before triggering an outcome eliminates any single point of failure and maintains the overall value of smart contracts that rely on external data. Blockdaemon has been a node operator since summer 2019. We are helping to run numerous price-feeds on various blockchains, such as Ethereum Mainnet, Binance Smart Chain, xDAI/Gnosis, Avalanche, and Optimism. Blockdaemon also serves as a data source, meaning, we enable other Chainlink node operators to use our on-chain data as one of several data sources.

Distributed Sources and Oracles

Most oracles are centralized, whereas Chainlink offers a network of decentralized oracles, meaning that Chainlink’s oracles are subject to the blockchain consensus mechanism and therefore ensure the reliability and security of data. For example, when a user puts in a contract request with the Chainlink protocol the request is contracted out to multiple oracles, which may draw information from various sources, increasing the data’s reliability and ensuring that smart contracts are carried out accurately and with no malicious intent.

The Chainlink Reputation Contract

Chainlinks' native cryptocurrency token LINK is built on Ethereum in accordance with the ERC-20 standard for tokens. The Chainlink Reputation Contract considers the size of a node’s stake (among other criteria) when matching nodes with requests for data. Nodes with a greater stake are hence more likely to be chosen to fulfill requests (and therefore earn LINK tokens for their services. The LINK token lives as a sub-token on the Ethereum blockchain). Additionally, the Chainlink network punishes faulty or dishonest nodes by taxing their stake of LINK for poor service.
