10 Lessons: Design Thinking for Blockchain

Over the past fifteen months I’ve facilitated eighteen design thinking workshops to explore the application of blockchain to customer projects.  Most of these (actually 12) have been in the finance industry, and in Europe (specifically 15).  Some interesting lessons and reflections emerge. First a little context . . . We use a standard approach for customer projects as shown […]

Combating Fake News with Document Provenance

With all the talk about “fake news” it’s interesting to reflect on the roles of intelligence agencies (government and civil), the similarities and differences between their work and investigative journalism and how a clear, trusted document provenance will help them both in proving the validity of their work products. Let’s start with the intelligence agencies.  […]

I recently had the honor of joining a panel at the Responsible Business Forum at Oxford University’s Saïd Business School sponsored by the Mars Catalyst organization.  The conference brought companies together to share their experience of tackling key challenges in their ecosystems to generate financial, social, and environmental value at scale.  These business practices are […]

Ten things blockchain is NOT

Over the past months, I’ve written much about how blockchain – as a trusted, distributed ledger with shared business processes – can provide transformational value to almost all industries. One of my colleagues recently suggested I should also say what blockchain is not.  Since I try hard not to practice blockchain religion (“blockchain is the answer, what’s […]

Boiling Down Business Blockchain

We are making considerable progress with blockchain customer projects – at the time of writing, we have some 31 public references!  But there is still too much gobbledygook and technical waffle given when answering the simple question “So exactly what is blockchain, in business terms?”. Maybe this will help . . . Blockchain is a trusted, […]

Unpacking a blockchain use case

Careful choice of use case is critical to a successful blockchain first project.  In a previous blog post I have discussed the application of ideation and prioritization techniques, and blockchain fit tests to use case selection. I will now outline ten questions which can be used to understand the selected use case in sufficient detail […]

Hyperledger Composer: accelerating blockchain time to value

We often get asked “where’s the business case for this blockchain project”.  Blockchain is new yet offering considerable transformational potential, so this is a hard question to answer.  We usually suggest  that our customer understands what blockchain is, works with us to find a suitable use case then embarks on first project together using an agile […]

Blockchain for government: building trust; demolishing bureaucracy

To build trust, governments strive to be as open, transparent and collaborative as possible.  To demolish bureaucracy, they seek to streamline citizen interaction, financial transactions and contract management.  All too often, they fall short of their own ambitions on both counts. Some fifteen months ago, I published my blog Blockchain for Government.  So much has […]

Figure 1: Core Components of […]

Building a Blockchain Business Network

Use of Hyperledger Blockchain only really makes sense when a business network is involved.  The techniques for driving blockchain value across the network are evolving as the blockchain technology matures into business usage. Just last week, a dozen participants came together across three continents to prove the technical feasibility of building a business network on Hyperledger Blockchain, as […]

Blockchain for Asset Registration

Friends in our government industry team tell me that there is much interest in their customer base in two specific use case clusters.  The first is around supply chain – which I blogged about some time ago (at this link > http://bit.ly/BlockWhere) – the second around asset registry, which is the subject of this post. What […]

Blockchain: Tackling Tax Evasion in a Digital Economy

The fast-growing digital economy is a nightmare for governments looking to maximise tax revenues and minimise tax evasion!  A recent report “Tax Challenges in the Digital Economy” from the policy department of the European Parliament states: “Digital goods are highly mobile or intangible, physical presence of a company in the market country is often not needed in […]
