Chainlink’s Meta Oracle Capabilities for DeFi

Chainlink’s upcoming Meta Oracle capabilities allow the combination of their widely used on-chain price reference data with any/all on-chain data sources. This expands how existing on-chain data and off-chain data interact.

The meta oracle functionality extends Chainlink’s capabilities to aggregating and reacting to any/all on-chain data. It allows users to combine any on-chain values with Chainlink’s own high quality off-chain data sources, while setting key conditions about how a smart contract should receive, react to and rely on this larger combined data set. The goal is to give smart contract developers more choice when deciding which data resources will be used to build and improve their DeFi smart contracts.

Chainlink’s meta oracle functionality allows smart contracts to use Chainlink for creating complex aggregations of various on-chain data, as well as setting additional conditions for interacting with that on-chain data, such as decentralized exchange prices, other on-chain oracle reports, and any other data generated or placed on-chain. While Chainlink already provides highly accurate off-chain data for DeFi, insurance, gaming and many other industries, some of the data being generated on-chain can be usefully combined with data about what’s going on in the larger off-chain world. Combining this data using Chainlink’s off-chain aggregation or an on-chain meta oracle smart contract capability can sometimes provide useful functionality.

Learn how Chainlink’s Meta Oracles can be used to implement pricing bands and reduce pricing inefficiencies. Follow the link here.

QANplatform Integrates Chainlink Oracles to Connect with Real-World Data

Quantum-resistant QAN blockchain platform integrates Chainlink’s decentralized oracle framework to allow its developers to obtain tamper-proof real-world data for its multilingual smart contracts. QAN developers will be able to build more complex smart contract designs that leverage resources from outside the QAN blockchain platform.

QANplatform is a quantum-resistant blockchain platform powered by blockchain fintech brand Centrum Circle. QAN uses Lattice-based cryptography, making it resilient to quantum attacks, which are expected within the next five years and introduce vulnerabilities to most major crypto networks.

While QANplatform offers numerous security properties that make it enticing for long-term viability, like all other blockchain platforms, it lacks the ability to interact with data and systems that are not on the QAN blockchain. Since the most trusted data sources often exist on non-blockchain systems, there needs to be a way to access them in a manner as secure as the blockchain itself. This is known as the oracle problem and Chainlink is the premier oracle solution for most of the blockchain ecosystem.

Through Chainlink, developers can protect against a centralized oracle being a single point of failure by decentralizing the data delivery process using multiple oracles to gather the same data point and then aggregate their responses together. They can also protect against one data source being the single source of truth by gathering data from multiple sources and aggregating them together using customized models, such as producing an average, tossing out outliers, etc.

By combining QANplatform’s highly secure, quantum-resistant blockchain with Chainlink’s decentralized oracle network, users get access to a secure and reliable end-to-end solution that is fully connected to the real world. This enables QANplatform’s developers to create logic based on real-world situations, which is a huge value-add to the network.

Some of the potential use cases we are considering once integrating Chainlink, include:

  • Decentralized sourcing of the QARK/USD price to enable enterprises to calculate transaction fees in USD, yet pay with QARK on the backend.
  • Secure connection to IoT devices to open up new insurance, supply chain, and logistics products

Chorus One is Joining Chainlink as a Node Operator

Chorus One is excited to join the Chainlink community to help make blockchain adoption for real-world applications a reality. Chorus One is building validation and staking infrastructure for Proof-of-Stake networks. They have valuable experience in working with networks that rely on price oracles. They will be supporting the network with their infrastructure and knowledge of staking systems. It will offer staking for Chainlink when it goes live.

A staking incentive model is in the works that will allow LINK holders to stake their tokens with trustworthy node operators. This will help create a permissionless, decentralized network focused on reliably providing accurate data to be consumed by blockchain applications.

Chorus One strongly believes that the protocol has a good chance of becoming the standard for providing off-chain data to blockchain applications. Their thesis is further supported by the transition of several major decentralized finance projects on Ethereum to the Chainlink network instead of running their own oracle implementations. Examples include Aave and Synthetix, which made this decision after their early price reference feed was exploited by a trader.

Chorus One looks forward to publishing further content around Chainlink and the planned staking implementation in the future.

Arbitrum and Chainlink

Arbitrum supports secure smart contracts using an off-chain protocol that gives smart contract developers the flexibility to move most of the work of smart contract execution off-chain, to nodes running the Arbitrum protocol, while maintaining the trustless security of Ethereum.

Arbitrum offers uniquely low cost and high throughput capabilities by computing solidity in a way that doesn’t have to be fully computed by every node on a single public network. Similar to how Chainlink applies scalable security to real-world data, Arbitrum provides a scalable security model for trust minimized off-chain computation. As the value of an Arbitrum off-chain computation increases, developers can always add Chainlink oracles/node operators to increase the number of validators securing their specific computation’s overall security.

Combining Arbitrum’s unique trust-minimized smart contracts together with Chainlink’s high quality node network as secure validators of those computations, as well as their ability to create secure connections to key external resources, provides a greatly improved, more scalable, and extremely cost efficient off-chain development stack for smart contracts. This makes it simple to launch highly secure, externally connected, and cost efficient smart contracts that can meet the demands of interoperability with other key systems, while being used for computationally intensive use cases that want to rely on the security of Ethereum.

Decentralized networks of Chainlink nodes running Arbitrum can validate a solidity smart contract, retrieve external data inputs, scalably compute the smart contract with associated correctness guarantees, push these contract outputs and proofs on-chain, and send a provable result to the user’s on-chain contract once the arbitration period has ended.

Chainlink nodes will be able to add an additional layer of security by staking LINK as collateral to back their computations. These crypto-economic guarantees will allow the system to scale to secure more and more value over time, especially given Chainlink’s unique ability to progressively add additional high quality nodes to secure any specific Arbitrum computation as it grows in value.

Arbitrum has full solidity support and accessing Chainlink data on Arbitrum will be just as simple as accessing it directly on Ethereum.

Swipe Leverages Chainlink to Bring Decentralized Pricing into the Swipe Network

Swipe recently collaborated with Chainlink. This integration will enable the Swipe platform to access Chainlink’s decentralized price feed oracles, particularly their ETH-USD Price Reference Contract and a custom-built decentralized price reference network for SXP-USD, representing Swipe’s native token. By collaborating with Chainlink, Swipe will effectively address the security problems for off-chain connections that currently exist for users of the Swipe Network Wallet-Contacts.

Chainlink’s oracle solution will allow Swipe to create a stable, yet decentralized bridge between reliable off-chain prices and Swipe’s on-chain transactions. This is accomplished by having multiple Chainlink oracles evaluate the same data point, thus eliminating one oracle By decentralizing the data sourcing around token price conversions for point of sale transactions, such as through the SXP-USD decentralized price feed, Swipe users get more secure, reliable, and accurate pricing when buying, selling, and spending SXP.

About Swipe

Swipe is a wallet application and card platform that grants users access to buy, sell, and pay with 20+ digital currencies. Through its proprietary Swipe Network, users are enabled to convert digital currencies to fiat currencies on-demand. Learn more about Swipe by visiting Swipe.io.

Etherisc to Leverage Chainlink Oracles For Decentralized Flight Insurance Product

Etherisc is proud to announce that they have a working decentralized flight insurance Proof Of Concept on Rinkeby, an Ethereum testnet, that incorporates reliable data feeds delivered by Chainlink. By combining the decentralized security of Ethereum with the decentralized oracle framework of Chainlink, users have access to a trust minimized insurance product that is secure end-to-end.

Parametric insurance built on top of decentralized infrastructure is one of the most exciting frontiers of innovation in the insurance industry. This insurance model foster new product designs and increase market participation, but it redefines underlying trust dynamics between insurance providers and policyholders.

Many of the problems in flight insurance revolve around inefficiencies and delays in claims processing that ultimately increase costs, extend process times, and cultivate mistrust between insurers and policyholders.

In the current model, users must manually file claims, which are then processed internally by the insurance company to verify whether or not the claim is entitled to compensation in accordance with their specific policy.

Blockchains can act as reliable and immutable engines for processing insurance claims thanks to their decentralized security. Smart contracts running on blockchains allow for the terms of an insurance agreement to be transformed into digital logic that executes based on predefined conditions, which neither party can tamper with. In the case of flight insurance, insurance policies can be programmed to process claims and make payouts once certain data is received, i.e. data about the flight’s status.
