Blockchain in 2018

We’re working on a list of blockchain trends for 2018 and are seeking professional insights and predictions. Questions: 1. What areas do you see as ripe for change using distributed ledger technologies? 2. Are you using blockchain currently – or plan to this year – to address a need, especially one outside of the area of finance/accounting? i.g. for authentication, protection of customer data, or seeking efficiencies in the supply chain? Predictions about what you’re seeing – or predict to see – take hold this year would be helpful. Stories of adapting blockchain tech to address problems are also great.
