Case Study Published – Blockchain In Hyperledger: Better Than ETL?

Keyhole Software Blockchain, Java Leave a Comment

In general terms, a blockchain is an immutable transaction ledger in a distributed network of participating peers. Its data includes a string of transaction records secured with cryptography. Benefits of blockchain can include decentralization, immutability, provenance, and finality.

While Bitcoin and Ethereum cryptocurrencies brought blockchain to the forefront of technology headlines, the technology underneath has true potential value for the enterprise outside of the cryptocurrency space. The features provided by blockchain technology can lead business benefits like lower costs, higher efficiency, and lower risk. Seeing a technology actually applied reinforces understanding. It can also be a genesis for new ideas.

In this case study, we walk through a Hyperledger Fabric reference blockchain with a focus on showing the potential value for enterprise-level organizations.

The potential cost savings of blockchain is one of the benefits not really discussed as a whole. However, we at Keyhole believe it could be a significant feature benefit. The goal of this case study is to help reinforce this…



Blockchain Implementation With Java Code

David Pitt Blockchain, Java Leave a Comment

Bitcoin is hot — and what an understatement that is. While the future of cryptocurrency is somewhat uncertain, blockchain, the technology used to drive Bitcoin, is also very popular.

Blockchain has an almost endless application scope. It also, arguably, has the potential to disrupt enterprise automation. There is a lot of information available covering what and how blockchain works. We have a free whitepaper that goes into blockchain technology (no registration required).

This blog will focus on the blockchain architecture, particularly demonstrating how the “immutable, append-only” distributed ledger works with simplistic code examples.

As developers, seeing things in code can be much more useful in understanding how it works, than simply reading technical articles. At least that’s the case for me. Let’s get started.



White Paper Published: Blockchain for the Enterprise

The Keyhole team is proud to announce the publishing of a new white paper: Blockchain For The Enterprise. 

While Bitcoin is on the minds of the general public worldwide, blockchain is on the minds of information technology professionals. It is the underpinning technology of the powerful and popular cryptocurrency. What exactly is blockchain and how will it help my business? That is what this white paper seeks to answer.

In the most simple terms, a blockchain is a distributed data system for keeping a ledger of immutable data transactions. We will explore additional complexities through this document, but the simplest way to think of it is a highly distributed transaction log. If you happen to be a developer and you are using Git for source code control, you are already using some of the distributed blockchain elements.

In this white paper, we discuss a number of topics related to blockchain with a particular emphasis on the enterprise. This document will be in three major parts. Part one will include a brief overview and history of blockchain, part two will include a deep technical dive, and the third part is written with the intent to aid managers and executives in their decision making in regards to blockchain…
