Tezos XTZ Oracle

Tezos (XTZ) Community Excited about the Harbinger Oracle and the Spruce Systems Inc Digital Identity Project

August 31, 2020 Off By Steven Anderson

The recent excitement in Tezos community was following the announcement of Harbinger, a decentralized Price Oracle on Tezos. Harbinger permits anyone to participate in Oracle updates by making use of signed price feeds from trusted sources. Therefore, provides a crucial component for DeFi infrastructure on the Tezos Blockchain.

More than 6.8 billion dollars of value is said to be locked in different DeFi protocols on chain. These protocols require accurate data feeds to function. Harbinger is a public good, which provides for the best building block to do that on the Tezos blockchain.

Of note, Harbinger is already live on the Tezos Mainnet! The price data for 8 asset pairs from

Coinbase is already available on chain.  Updates are posted to the data once an hour; however, it has been stated that anyone can provide more frequent updates by setting up their own posters!

More than anything, Harbinger is cheap.  Further, the updates can be applied on chain for as little as .008 XTZ or for about 2 cents USD.

Along with this launch, there is a reference implementation for anyone to sign in to Harbinger price feeds. They have also provided out of the box implementations for @binance, @Gemini and @okex @blockscale and are graciously signing these feeds.

Further, open sourcing a hosted service to post prices from signed feeds into Harbinger Contracts, which is a CLI for deploying Harbinger, and an open source toolbox to permit anyone to build on Harbinger.

Those who are interested in building on Harbinger can get in touch on DMs which are open to chat about how to leverage this.

Sydney Ifergan, the crypto expert tweeted:  “Bringing Digital Identity to Life is the recent happening on the Tezos Ecosystem.  Spruce Systems, Inc have detailed a lot in this regard on Medium.”
