A committee of the UK House of Lords, the upper chamber of
Parliament, struck a curious and at
times critical tone when discussing
blockchain technology and its impact on finance and government.

During
an afternoon hearing of the The Economic Affairs Committee, members
heard from academics and representatives of the blockchain industry, as
well as Ben Broadbent, the deputy governor for monetary policy of the
Bank of England. Lasting about three hours, the hearing demonstrated a
mixture of genuine interest and skepticism on the part of committee
members.
It was the first major committee discussion of the technology within Parliament, and follows a period of growing interest
within the UK government to pursue possible applications.
In addition to Broadbent, witnesses who spoke included Digital Asset
Holdings CEO Blythe Masters (who spoke via phone); 11:FS co-founder and
director of blockchain Simon Taylor; Imperial College Centre for
Cryptocurrency Research associate director Dr Catherine Mulligan;
Gresham College professor of commerce Michael Mainelli; and PwC
transformation and assurance director Lord Spens.
During his appearance, Broadbent discussed both the concept of a
central bank issued digital currency – which he indicated is an
evolving, years-long process – as well as the technology’s broader
impact on financial markets.
Broadbent went on to frame the conversation about blockchain within a
broader question of how financial markets should be structured at all,
telling committee members:
"When you think of things on these scales, the benefits
are clear and quite large, and so are the costs. And what I was really
trying to say is, even though this is a very new technology, I think
it's possible, once you think through, to realize that some of the big
questions involved are very old, not to say ancient."
On bitcoin
Committee members asked a number of questions about bitcoin, though
at times the digital currency was branded as "anonymous" (bitcoin is by
design a pseudonymous system).
The topic came up when one member asked how the Bank of England would operate a central-bank issued digital currency.
Broadbent dismissed the idea that the Bank of England would use a
similar model, indicating that any network, if it came to fruition,
would be a permissioned one.
"We would never have a system like that," he said.
He elaborated on this point during the hearing, suggesting that
market participants wouldn't want an open, permissionless system when
asked whether financial institutions might use a bitcoin-like system to
escape regulatory scrutiny Further, he indicated that financial system
players would prefer one that includes oversight from regulators.
"I don't think that's what we would be most worried about, because I think people would want us involved," he added.
Doubts raised about welfare trial
One notable moment in the hearing came during the second of three
sessions, when the topic of a welfare payments proof-of-concept
developed for the UK government’s Department of Works and Pensions was
criticized by some members as ethically unsound.
Committee member and former UK chancellor Alistair Darling was
vocally critical of the move, echoing past concerns raised by privacy
advocates in the country.
"It does raise an ethical issue as to whether the state should know
if someone is spending money on one thing or another," he said.
In the back-and-forth that followed, Mulligan suggested that,
according to her best knowledge, the proof-of-concept calls for an
opt-in approach that wouldn’t require such oversight. That said, she
conceded that there are privacy concerns that need to be worked through
before such a system becomes production-ready.
Mulligan told the committee:
"There are, really, a number of profound issues that need
to be looked at from a regulatory perspective, and also these kind of
moral and ethical questions, it raises them, very large questions for
our society if we wish to use these technologies."
