No, “Blockchain” is not a solution looking for a problem

I have heard this comment many times:

“Blockchain” is a solution looking for a problem.


That is incorrect – here’s the problem statement, originally articulated in 2008:
Bitcoin whitepaper

The problem statement, to paraphrase, is

“How do people pay each other electronically without being at the behest of Financial Institutions?”

The proposed solution is:


Bitcoin uses blockchain technology, right?  Yes it does.  Of course you remember the 2015 rhetoric “I’m not sure about Bitcoin, but I’m interested in Blockchain, the underlying technology” – enthused by people who had read something on some website (or perhaps on a Dilbert) then stood on a stage and waved their hands?

That was 2015.  This year, R3, arguably one of the world’s premier companies pitching “blockchain”/”distributed ledger”/”fabric of finance” (no one actually knows the difference) said on April 5 that they are not using blockchains to solve Financial Industry Problems:


That’s great!  That’s a step forward! Banks have problems where blockchains aren’t really the solution.  R3 & DA are attempting to solve those existing financial industry problems and, according to Morgan Stanley in a 2 June 2016 report, various intermediaries are seeking to use the technology to defend the clearing monopoly (oh, how far we are away from “blockchain to disrupt finance”):

MS June 2 2016

The way I understand this is ASX, who according to Global Investor Magazine, has paid close to $15m for a 5% equity stake in Digital Asset (valuing Digital Asset as an enterprise worth USD $300m prima facie), is exploring ways to use “blockchain deployment” to stop other people from doing clearing-related activities.


So what next?  Here are some things to think about:

  • Public blockchains (ie Bitcoin) promise to solve the problem of having your assets held by Financial Institutions.
    • You may not think this is a problem
      • Yes, this is a problem: you wouldn’t voluntarily give your money to gambling addicts in order to participate in normal life, if you didn’t have to.
    • Why are we paying money to people/companies to keep ledgers of who owns what?  This seems silly.
  • Public blockchains in their current form (ie Bitcoin) may not work
    • Bitcoin has kind of worked, more or less, give or take, with a few hacks, etc, for 7 years.  Right now it kinda works.  It may yet fail. No one knows.
    • Sure, Bitcoin transaction fees are going up.  But they are linked to the cost of data (reasonable) not the number of zeroes on the cheque (lol)
      • The other day I paid the BTC equivalent of USD $5 to move the BTC equivalent of USD $15 million from one owner to another, and it settled (as far as anyone concerned agreed) within an hour.  There was no bank or custodian in sight.  Call me if you can do better.
      • The biggest scam* in finance is editing rows in databases and charging a percentage of value moved – banks and custodians are laughing all the way to the, er, bank.
        • *One of the biggest scams
        • Yes, financial drag on payments is a drag on GDP/economy/economic growth by any measure
    • Sure, proof of work is probably not the most efficient way of keeping baddies out – there may be better ways.
      • This is nerdy but important (in bitcoin) point.
      • The people thinking about this are working hard, they’re not sitting around waiting to retire.
    • Coloured coins (graffitiing on Bitcoin’s blockchain) may not be “incentive-compatible” ie they may make blockchains top-heavy and screw with the mining incentives, and they might not be the best way to solve the problem of paying people to tell you what you own.
      • Why are we paying people to tell us what we own in the first place?
  • Bitcoin may fail; other commodity-like currencies/things may fail.  It’s just an experiment, guys (yes that’s my hedge 🙂 ).


But for goodness sake, it’s not a “solution looking for a problem”.

You may not like the problem.  You may not agree that “the problem” is a problem. That’s fine, but “Blockchain is a solution looking for a problem” isn’t true.

Happy to take comments.

    Your indentation needs work; makes reading difficult.

    The issue isn’t really that blockchain is a solution looking for a problem <– that is clearly articulated in the use of bitcoin to solve peer-to-peer value movement without the banks.

    The issue is that people are abstracting the blockchain tech AND trying to use it as a solution to solve alternate problems, because using it to solve the movement of funds without banks is a dirty notion to the banks and the finance establishment.

    It has now been co-opt by the parties it was meant to disrupt, a great perversion of the ideals that created it in the first place…

    Love your articles Antony. Right to the point again and they help me to structure my thoughts and statements in discussions with sceptics :-).

  3. “you wouldn’t voluntarily give your money to gambling addicts in order to participate in normal life, if you didn’t have to.” – Well that is not a correct overview of banking. 99.99% of banks do not “gamble” or trade. And with Volcker, even the large investment banks cannot trade. And even if they can trade and lose money, my deposit is safe because of FDIC insurance.

    “Why are we paying money to people/companies to keep ledgers of who owns what? This seems silly” – I do not know which bank you bank with, but my bank has NEVER charged me for my checking / savings accounts.

    “The other day I paid the BTC equivalent of USD $5 to move the BTC equivalent of USD $15 million from one owner to another, and it settled (as far as anyone concerned agreed) within an hour. There was no bank or custodian in sight. Call me if you can do better.” – perhaps you should try Western Union. I use them to move money from the US to India. The money moves in a day and I do not pay any fees and I do not get scammed by the exchange rate differentials – I know, because I checked the USD / INR exchange rates on Bloomberg and compared it to what Western Union charged.

    Full disclosure – I do not work for any financial institution, and I do not own any shares of Western Union

  4. The main problem with block chain technology is that it relies on the user to protect their machines. Whereas a large institution has more resources to keeping our assets secure, assuming they were trying to do that. Trustless banking is uninsurable banking.

  5. Blockchain is the enabling technology for bitcoin, but that’s it. It does not scale because it has a basic issue with security, namely that cost must be high enough to prevent cheating. Neat tech, but no economic rationale outside of original use case, bitcoin.

  6. Good Informative post. Great to know about another prospective of Blockchain that what is their limitations.
