From YouTube: Introduction of Chainlink Price Feeds, PRVD Baseline zk Proofs, and IPFS to SAP S/4 HANA

Description

Provide's SAP Architect and Developer Evangelist Ryan Fleischmann introduces the Provide proUBC Chainlink Fall 2022 Hackathon entry - integrating Chainlink Price Feeds from Polygon to SAP S/4 HANA to update foreign currency and digital asset prices in SAP. Ryan also exhibits the price feedback mechanisms from SAP back to business partners and the Chainlink decentralized oracle network using PRVD Baseline zero knowledge proofs, Provide Shuttle, and IPFS.

Greetings chain link, web3 and sap communities. My name is Ryan Fleischman and I. Am the representative from provide Technologies for the chain? Link fall, 2022, hackathon I? Am the sap architect and developer evangelist at provide, and this fall. We have a very special hackathon entry.

A

Our submission integrates chain link price feeds into the sap S4 Honda enterprise resource planning system, the number one Erp system used by Fortune, 500 businesses and other Global organizations for finance supply chain and other business processes, and so a few words we used the chain link price feeds to update the core foreign currency rates in sap.

A

This hackathon entry enables SAP systems to use chain link price feeds to optimize their off-chain business processes with Fiat currencies, while also obtaining price feed information on digital assets such as Bitcoin ethereum and many others, supported by chain link price feeds.

A

This serves as a technical and financial Cornerstone towards enabling large Enterprises to engage with web 3 based business models, whether it's a Euro, an ether or even something else in between Enterprises using sap, universally benefit from chain links, price feeds, fairness, transparency, decentralization and overall high performance and determining price data as sap S4 Hana is not a blockchain system, but rather an Enterprise software typically deployed behind corporate on-premise or private Cloud systems.

A

We've included some additional feedback mechanisms to bring further resilience into how chain link price feeds would be used across multiple, disparate Standalone sap instances.

A

We considered it very important to implement an approach that could lead to SAP systems, contributing their pricing. Data back to the chain link, decentralized, Oracle, Network itself. Here are the two feedback mechanisms we created. First after the chain link. Price feeds are used in sap to update the foreign currency exchange rates. The sap Abbot program we created for this hackathon emits a zero knowledge proof.

A

This zero knowledge proof can be used amongst a Loosely connected network of business partners to securely verify that they are harmonized synchronized to the exact same exchange rates, and this is immensely uh useful for cross-border finance and multi-party. You know business coordination, this CK proof as it exists on the prvd network ethereum layer 3 could also be used for multitude of other purposes on chain. Two.

A

Second, the sap about program generates a file that is shared to ipfs.

A

The file on IPS could be shared between other business partners, but what really excites me is that this becomes a way by which the sap ecosystem itself could contribute pricing data back to the chain link, decentralized, Oracle Network, given the trillions of dollars and million Myriad of diverse B2B and b2c transactions conducted through SAP systems. Today, it's an exciting prospect to have so many of those ordinary systems of Commerce begin to contribute data back to chain link overall, we're very proud of the business and technological use case we built for this hackathon entry.

A

This is among the very first open source examples of a smart contract, zero knowledge, proof and ipfs integration to sap offered through our own open source project known as pro-ubc, and also aided by provides Loco designer shuttle.

A

If you'd like to take a quick glance, here's our Abba program executing a chain link price feed on polygon, creating a zero knowledge proof and Publishing data back to ipfs. There's really a lot going on here and I had to speed it up for this video to get into the time limit for the judging criteria.

A

But if you'd like to see a longer video walking through everything step by step, a link will be provided in the description. Otherwise, you can always learn about our chain link. Hackathon entry in the repo provided I also recommend you check out the pro UBC core repo, as well as the pro UBC enablement docs, to learn more about Pro UBC, the open source, sap, op-op SDK for web3, prvd, Baseline and zero knowledge, and now ipfs too, and on behalf of the entire provide team. Thank you.
