Tezos (XTZ) Launches Delegated, Pre-Funded, Self-Sustaining Harbinger Price Oracles

Tezos has announced Harbinger — it’s very own oracle to deliver signed price feeds based on market data from multiple crypto exchanges to its network.

With Harbinger, Tezos is expecting the algorithmic stablecoins, lending platforms, and insurance products to kick off the new use cases.

Initial versions of the contracts are already deployed on mainnet and CarthageNet.

It’s not surprising that the network is delving deep into oracle as oracle projects have been having a lot of attention and gains in the crypto market. The crazy growth of Chainlink (LINK) is evidence of how much traction the decentralized off-chain data feed providers are getting.

Other popular oracles in the market are Band Protocol (BAND) and Augur (REP).

Take on the DeFi World

Now, Tezos, a liquid-proof of stake crypto network, is ready to make the most of the decentralized finance (DeFi) world through its oracle.

Oracles are critical to the fast-growing DeFi space, which has a total value locked (TVL) surpassing $7 billion, in order to have trusted price feed.

In its official announcement, Tezos announced that in Harbinger, “an account that pays for fees to update the price oracle can be delegated and pre-funded with tez,” much like staking.

This, it says, will enable the development of “self-sustaining” price oracles where the block rewards for participating in PoS consensus offset the fees required to keep the oracle data current.

“Having a reliable feed for on-chain price data is critical for DeFi lending platforms. Harbinger is an important building block for the decentralized finance ecosystem on Tezos,” said Robert Leshner, founder of Compound.

After taking inspiration from MakerDAO in StakerDAO, this latest one is based upon Compound’s Open Price Feed.

Harbinger is a set of tools and reference contracts, allowing anyone to become a ‘poster’ who retrieves prices from ‘signers,’ which are crypto exchanges to deploy a price oracle on the Tezos network, which then publishes cryptographically signed prices.

Moreover, Tezos smart contracts use callbacks to receive data to avoid reentrancy attacks.

In the meantime, the 13th largest crypto by market cap of $2.5 billion, XTZ is falling alongside the broad crypto market, trading at $3.43.
