INTERVIEW: How Banking's Big Fish Could Use Blockchain To Safely Share Data

Your correspondent recently attended ISLEXPO, an event focused on innovation and business growth hosted on the Isle of Man.
  As blockchain matures, large financial institutions will develop
  networks that use the technology to securely store and share
  clients' data with one another, a senior figure from the fintech
  space has predicted. 
  
  Although blockchain technology is still in its infancy, there are
  components of it that are “excellent” and present many
  opportunities for financial services firms, according to Brian
  Donegan, head of fintech and digital development at the Isle of
  Man government. 
  
  One opportunity in particular, he said, is blockchain's potential
  to create “notarised identities”. 
  
  He described a notarised identity as a digital passport that
  holds a client's data, which could be interpreted by all
  institutions as a “single source of truth” to comply with
  anti-money laundering and know-your-customer regulations. This
  would ease the administrative burden currently placed on clients
  by eliminating duplicative onboarding processes, Donegan
  said. 
  
  “We have to accept that blockchain cannot be uninvented – it's
  here to stay and it is being refined quickly,” said Donegan on
  the sidelines of ISLEXPO. “We're seeing clarification in the
  marketplace, particularly from larger financial institutions,
  which are saying that they like the idea of private permission
  blockchains [that cannot be publicly accessed].”
  
  Fintechs, banks and regulators from across the world are forming
  consortiums and working groups, such as 
  R3 and the 
  Enterprise Ethereum Alliance, as they push to create
  proof-of-concepts using the nascent technology.
  
  “Our vision for the future is that if we see financial
  institutions adopting this collaborative approach, then growth
  [of blockchain use] will be exponential and the major players
  will develop their own private blockchains and then connect
  them,” Donegan said. “What we will have is a network of private
  permission blockchains that will look like a 21st century-version
  of the [data systems] that are in place today.”
  
  A blockchain is a virtual distributed ledger of transactions
  shared peer-to-peer that can record ownership across a public
  network of computers rendered tamper-proof by advanced
  cryptography. 
  
  The technology is causing a stir within the financial services
  sector as its supporters believe it could reduce hidden expenses
  in the financial system by ousting inefficiencies across areas
  such as payments, syndicated loans and equity clearing.
  
  Although blockchain rose to fame as the platform underpinning the
  controversial digital currency bitcoin, its uses are incredibly
  wide-reaching, and financial services firms realise this, Donegan
  said.
  
  “In 2009 [when bitcoin was created], it really launched the first
  iteration of blockchain technology which happened to underpin a
  digital currency, but it could have been anything,” said Donegan.
  “People were blind-sighted by bitcoin and didn't see the true
  value of the underlying technology, but I think that is starting
  to change.”
  Changing use
  Even now, there are numerous organisations using blockchain
  technology to innovate the ways in which certain traditional
  asset classes are held.
  
  For example, the UK's Royal Mint has announced it will launch a
  
  new online gold trading platform that uses blockchain to
  record ownership of the precious metal stored at its on-site
  bullion vault.
  
  Additionally, Dutch lender ABN AMRO collaborated with technology
  behemoth IBM on a project exploring 
  how blockchain could help streamline real estate
  transactions. IBM also helped develop a 
  blockchain-based solution that facilitates the administration of
  a private equity fund managed by Unigestion.
  
  Donegan explained that over the past two years, the Isle of Man
  has seen “a lot of the hype around bitcoin die down”, as firms
  increasingly shift their interests towards blockchain. 
  
  By the end of this year, financial institutions will have spent
  more than $1 billion on blockchain-related projects, according to
  boutique investment bank Magister Advisors, and more than
  three-quarters of financial institutions plan to implement
  blockchain-based solutions by 2020, a 
  recent report from PricewaterhouseCoopers shows.
  
  Because of blockchain's ability to indelibly store and transfer
  data, Donegan suggested that the technology could help firms
  comply with the raft of new regulations, such as 
  GDPR and MiFID II, looming on the horizon. (To see a related
  item on potential tensions between these two regulatory
  processes, see
  here.)
  
  How this will work in practice, however, is unknown at this
  point, Donegan admitted. 
  
  “There is definitely a role for blockchain to play in the GDPR
  story, we just aren't sure how this is going to look yet,” he
  said. 
  
  And the road to business as usual for blockchain remains in flux
  as industry participants grapple with regulatory and
  technological challenges, Donegan added. 
  
  “If you compare blockchain now to the internet in the mid 1990s,
  the simple reality is we are no where near at the level of
  languages and HTML that existed for the internet at that time,”
  Donegan said. “With blockchain, we don't have the underlying code
  that we had for the internet back then – but it will come. The
  next two to five years is going to be crucial for how this will
  all be defined.”
