How HUMAN is used as a DeFi oracle

2 min read

The HUMAN Protocol Foundation has begun work in DeFi. The work on data labeling will continue, but the Foundation will increase focus on providing a suite of oracles to increase the decentralization and robustness of DeFi protocols. 

We’ve already begun work with Pyth, a DeFi oracle provider, to offer our job-launcher and work verification technology to power DeFi data feeds. Check out their whitepaper to see just how HUMAN Protocol will work with them!

Oracle failures can be massive. For instance, a trading bot acted on a price oracle relaying the price of KRW as 1000x higher than was true, and ended up winning out $1 billion from Synetix. This is just one example – there are many more, which clarify the need for a secure, robust oracle infrastructure in DeFi.

An introduction to oracles in DeFi

Oracles are fundamental to blockchains – to their functioning, their integrity, and success. A blockchain with faulty, poor, compromised, or centralized oracles, loses the very purpose of its design as a distributed network. 

Oracles provide and record data from external sources to smart contracts on-chain; they are a critical component of smart contract execution. Because oracles can be used to pull any real-world data on-chain, they can massively expand the utility of blockchains. They do, however, also pose a risk as a point of failure, a point of reliance – particularly as the blockchain has to “trust” the data it receives.

HUMAN as an oracle 

In using HUMAN Protocol to power an oracle — the process is as follows:

  • A DeFi protocol requests an update on the price of Bitcoin 15 minutes ago
  • They launch the job as a smart contract on HUMAN Protocol
  • The job is distributed to a specified number of respondents 
  • The worker, in this situation, is asked to follow a link to a reliable source of pricing information, from which they can then assess the price, and enter their findings via the DeFi protocol’s HUMAN API.

The primary use case in this scenario would be for arbitration of disputes. Dispute management is something that robust decentralized protocols must implement if they are to be truly trusted. If, in DeFi protocol, two parties disagree that the price pairing of USDC:USDT was not precisely 0.9999967, then having a recourse, whereby a group of human workers can singularly and independently check that information and relay it on-chain, is valuable.

The benefits of HUMAN Protocol powered oracles

  • Progressively more decentralized. The oracle itself is decentralized — it is not reliant on one feed, but many individuals. 
  • On-chain data. The HUMAN Protocol oracle data is written on-chain — this makes the data easily digestible and available for on-chain protocols. Seamless, easy data is key to adoption and utility.
  • Safety and robustness by volume. Any mistakes will be picked up by virtue of the volume sample size.
  • Dispute management — if there is a dispute amongst DeFi protocol participants, having the opinion of 1,000 individuals attesting to a given price can help arbitrate pricing concerns. 

The scope of DeFi oracles — areas HUMAN could be applied to

The entire ecosystem of DeFi relies upon reliable price information. Below are just a few examples – the list is by no means exhaustive, but highlights the many ways pricing information is used across DeFi.

  • Lending protocols — price oracles provide data on the value of an underlying asset to avoid under collateralized loans. 
  • Crypto-backed stablecoins — DAI, for example, which is pegged to a USD retains its price by using collateralized debt, denominated in ETH. Oracles are required to relay the price of ETH, which allows the protocol to determine when DAI collateralization needs to be adjusted. 
  • Decentralized prediction markets  – rely on trustworthy reports of event outcomes in the real world to payout correct results fast. HUMAN has already provided a solution to this with IMOO – the information market on-chain oracle.

The voice of many

DeFi protocols are designed to return power and rewards to individuals. They are designed to cut out the large, central entities that usually govern financial services. It makes sense, then, that they are built upon a technology powered by individual humans; a technology that values and empowers the voice of individuals, coordinates them as the voice of many, and rewards them for their work and contribution, no matter how small.
