Mapping out the blockchain ecosystem in London

London is one of the oldest and largest financial centers in the world, and the UK as a whole is the world's largest net exporter of financial services. Blockchain technology's arrival on the scene has brought new innovations to London's well-established financial realm, paving the way for a host of new blockchain companies. These companies run the gamut with the services they provide, and new ones spring up with some regularity, resulting in a vibrant and active blockchain ecosystem.

With its storied history as a global financial hub, London has been a natural fit for blockchain related startups. This becomes apparent when looking at the number of blockchain companies that are either headquartered in or at least hold an office in the city. The Block has mapped out a total of 91 firms in London across 15 sub-categories that are working to bring innovation through blockchain technology or cryptocurrencies.
