Hashed Timelock Agreements in Hyperledger Fabric

Hashed Timelock Agreements, or Contracts, have emerged as an important concept in the cryptocurrency space in order to perform transactions across ledgers – and I feel could be a valid mechanism to handle the issue of performing verifiable cross-channel transactions in Hyperledger in some use cases. The basic concept of a Hashed Timelock Agreement (HTLA) is that it allows for a conditional transaction (which I have deemed a ‘proposal’) with a cryptographic challenge which ensures it can only be completed by a pre-defined party. This can be chained through multiple intermediaries, which can enable two organisations who do not share a channel to interact, and for transactions to be confirmed across channels.

Integration, Process and Visual Builder

OIC makes integration easy with ODI

We know OIC (Oracle Integration Cloud) is capable of file based integration for ERP over API.
And we do know that ODI (Oracle Database Integrator from Data Integration Platform Cloud) is capable of ingesting large file and processing it for ERP through the database layer aka ETL / ELT.

Enter The Robots (A Different Kind)

Last week, I had the opportunity to do some work and part of the engagement there was to integrate some data. Easy right? It’s not that hard especially with the technology and standards we have these days. However, what was not apparent upfront until after some digging (ie research), an email and a phone call that there were no APIs to be found. “Ha ha ha … we’ve got you … there is no way you can do it now” So the challenge was accepted and instead of time travelling into the future to find a new way of doing things, I went totally retro. And hence the title “Enter The Robots“. I didn’t go and create new versions of robots or AI. I don’t create a new quantum computing paradigm. What I did do was classically known as screen-scraping. “ick“, I hear from the crowd. “How dare you?“, someone else yells out. But I say this honestly, if there is no other way to integrate and capture data, then I rather do it knowing that it is a last resort.

In this article, I walk through a few of the tips and tricks with what’s currently available to help out in this situation.
