Teaming up on crypto
In the early days of blockchain, banks had no idea of what it was and what it could do for them. Their response: to team up in different consortia and to try and work it out together. Now everyone has got their heads around it (OK, kind of!), more and more banks are doing things alone on blockchain. Whether it’s implementing it internally like Wells Fargo or working with startups that have that same approach, it’s beginning to feel a bit less like the team sport that people claimed it was a few years back.
