The Reg A Conference is the largest gathering of deal-makers and investors interested in Regulation A, a prime opportunity for companies to network with like-minded business executives, as well as financial professionals who assist in bringing capital to companies (https://theregaconference.com/presenting-companies/). Many such companies are today basing their new business ventures and projects, and their search and submissions for funding, on blockchain technology applications. So-called cryptocurrencies such as bitcoin are just one example of the use of this functionality. The business implications of this secure online record-keeping tech are huge – and not only in cryptocurrency. This presentation provides a probing and extensive expert critique of blockchain, its cryptocurrency, distributed ledger and smart contract applications, and argues for a cautionary, savvy approach to implementing and investing in such business systems, on grounds of professional due diligence, rigorous corporate governance and wide experience of past leading-edge ICT systems failures.

I spent much of a whole year recently investigating why a major IT outsourcing deal broke down, and had given rise to the largest software contract dispute yet seen in the English High Court
Disputes over failed software construction projects raise interlinked technical and legal issues which are complex, costly, and time-consuming to unravel – whatever the financial size of the claims and counterclaims, the facts and circumstances of the contract between the parties, or the conduct of the software development
