Who knows for sure, but it was an interesting question posed recently in the media as Britain grapples with how leaving the European Union and its single market will affect trade, travel, and other logistics. The underlying idea that blockchain is based on an unchangeable shared source of truth has led some to suggest, such as in the FinTech article linked above, that smart contracts could lead to frictionless trade across borders, and solve new issues arising over crossing borders. Of course, since its inception, blockchain technology has been touted as a panacea to any number of problems—including in the state of Vermont, which last year piloted the use of blockchain for real estate transactions. Blockchain may or may not make the U.K.’s complicated Brexit process any easier, but it’s good to see that people are exploring all possibilities.
