Chainlink acquires a privacy-preserving oracle protocol from Cornell University

Published at: Aug. 29, 2020

Chainlink (LINK) has acquired a privacy-preserving oracle protocol DECO from Cornell University and one of its creators, Ari Juels, will be joining Chainlink as chief scientist. Previously, Juels served as chief scientist at RSA and has been teaching at Cornell University since 2014, one of the premier blockchain hubs in the world. He is taking a sabbatical to focus on his work at Chainlink. Along with his research partner Markus Jakobsson, he coined the term "proof-of-work".

DECO employs advanced cryptography and zero-knowledge proofs to provide enhanced privacy to its users. In a Cointelegraph interview, Chainlink's co-founder Sergey Nazarov said the integration of DECO will not only increase security of the project's infrastructure but will potentially create new use cases:

DECO-enabled Chainlink oracles will have big implications for smart contracts across enterprise, consumer, and even DeFi applications. Basically, any smart contract that was previously limited by private data will soon be able to function on a public blockchain like Ethereum without revealing any confidential information to the blockchain.

Nazarov believes that enhanced privacy will benefit both consumers and enterprises. The latter may be able to prove to each other the state of their data without revealing it, while consumers may be able to prove personal and financial data without providing access to it. He also said that this integration would potentially open up Chainlink's oracles to new data sources:

This is already leading to the addition of various data sources that were previously much more difficult to place on-chain, due to the fundamental nature of public blockchains being publicly viewable, and the private nature of various sources of high value data.

Answering our question whether Juels will be working full time at Chainlink, Nazarov said:

He has taken a sabbatical from his academic work and is currently focused on working on the Chainlink protocol. He will also be leading our entire research team, effectively stewarding the technical direction of the protocol as a whole.

Nazarov said that it can also create "endless possibilities" in the DeFi space - anything from credit scoring to proving loan collateral without the need to reveal sensitive information.

The remaining steps to mainstream institutional investment
It has been said that you only get one chance to make a first impression. Perhaps the best example of this old adage is the cryptocurrency space. From exit scams and money laundering, to unaudited code and high carbon footprints, the crypto landscape has spent the better part of the past decade scrubbing itself of its infamous past. For many, the sanitizing of the decentralized ecosystem was inevitable — simply a matter of when, not if. This mindset hindered the sense of urgency that should have been on display and may have ultimately contributed to the skepticism exhibited by mainstream …

Band Protocol CEO says that a single Chainlink data request costs $450
Band is one of Chianlink’s main competitors in the oracle space that is based on Cosmos technology. In a recent Cointelegraph interview, Soravis Srinawakoon, the CEO of Band Protocol, said: “If you look at Chainlink, one data request right now can take almost $450 because someone needs to submit the request data to ask for the data. Let's say 20 data providers need to receive that, respond to that with 20 transactions, and then the aggregation contract to do all the computation before returning the final result, all of these require a lot of gas.” Srinawakoon also provided a link …

A new Cardano-based project is handling oracles a lot differently than Chainlink
Cardano (ADA) is getting into data oracles ahead of the Goguen era that will add smart contract functionality, taking a different approach than Chainlink. The first oracles are being built in partnership with EMURGO, one of the companies in the Cardano ecosystem, and Ergo (ERG). The first two oracles are deployed on Ergo and provide price feeds for the two trading pairs: ADA/USD and ERG/USD. The new model introduces Oracle Pools, which are capable of incentivizing good and disincentivizing bad behavior. Ergo's core developer Alexander Chepurnoy told Cointelegraph that the idea involves major players in the DeFi ecosystem donating funds …

At present, your DeFi product needs to be multichain to be competitive — this is the hard (and exciting) truth of 2021. Whether you’re building a wallet, a lending service or a DeFi game, your target audience knows that there is more to the crypto space than Ethereum. And they expect you to provide the best of all worlds. It seems there will always be a debate about which blockchain makes for the best foundation for projects. Enhanced security, low transaction costs and formidable speed — there will always be a chain that offers bigger advantages. As the speculators argue …

Chainlink Verifiable Random Function v2 goes live on mainnet
On Wednesday, blockchain oracle solution Chainlink (LINK) announced the release of Chainlink Verifiable Random Function, or VRF, v2. As told by its developers, the new, improved version of the random number generator can reduce transaction fees by 60% compared to v1. Randomness is a core component of making nonfungible tokens, or NFTs, and gaming applications fair and secure. On their own, blockchains and smart contracts cannot guarantee randomness, but rather require an oracle network to deliver such solutions on-chain. Since its launch, Chainlink VRF (v1) has become the most widely adopted random number generator solution in the blockchain industry, fulfilling …
