Bank blockchain leader
By adopting blockchain, the global banking industry could save as much as $20 billion by 2022, according to the management consulting firm Accenture.

Santander certainly seems to think that will happen. It became the first U.K. bank to use blockchain to create a new international payments service, One Pay FX, which will first allow customers to transfer money between Santander accounts in Europe and South America.

Santander also piloted a blockchain effort for shareholder voting with Broadridge, JPMorgan Chase and Northern Trust.
