Blockchain technology captured the banking industry's imagination throughout 2015 and 2016, as financial institutions and tech companies seized eagerly on the concept. Defined broadly, a blockchain is a distributed ledger – a "shared source of truth" that is updated automatically, auditable in real time, relies on no single party and cannot be doctored. While it was originally developed as a feature of the digital currency bitcoin, technologists have been exploring a wide range of applications. To many it holds out the promise of huge cost savings and new products and services.
This year the rubber meets the road, as some companies expect to bring their experiments out of the labs and into production. Get up to speed on the current blockchain landscape, the pros and cons of various use cases, the fast-changing regulatory and technological challenges and the latest projects, ideas and developments in this frontier of fintech.
