Will the traditional banks survive Blockchain?

David Yermack, professor at the NYU Stern School of Business, states that in 10 years the numbers of banks have been halved. It’s hard to imagine that a technology can have such a large impact in such a short time, so how serious must we take this statement? I think pretty serious. Yermack is considered one of the leading experts in the field of Bitcoin and Blockchain. Not only Yermack, but also the consultancy firm McKinsey predicts the same fate for the traditional banks.
Ever since the introduction of Bitcoin banks are looking into this technology. One of the main problems of the image of traditional banks is the word trust, especially since the crisis of 2008. Blockchain could take all the trust issues away, making banks reliable again. No wonder every bank in the world is investigating this technology. But how far are they exactly, because we still haven’t seen a bank introducing a payment system based on Blockchain. Recently I read an article about the Bank of England testing a Blockchain based system and expect to use this by 2020.
So we’ve got an expert and leading consultancy firm predicting banks will eventually disappear, while banks are testing the same technology. I believe that the banks finally realize the threat that Blockchain is to their existence. If every transaction can be done with an intermediary, banks are nog longer needed for this. They can still provide extra services as a rate on your savings or a mortgage, but in order to be able to do all this they need the money on all the saving accounts. The whole idea of Blockchain is a decentralized system, which not applies in the case of the Bank of England. It’s also a big question whether governments will allow the Blockchain to happen. Bitcoin still isn’t recognized as an official currency. I’m very curious to see which way this interesting technique will go.

Why Blockchain is bigger than Bitcoin

People often have the idea that Bitcoin is the same as Blockchain technology. This is partially true, because Bitcoin is based on the technology. It is the first and currently only large scale successful implementation of Blockchain technology. However, the potential of Blockchains exceeds what Bitcoin is today. So why is almost every big company in the world currently looking into this technology? And what is the reason that this technology will change the world, according to McKinsey?

The definition of Blockchain
To understand why Blockchain is bigger than the Bitcoin, we need to look at the definition of the technologies. There is no standardized definition for Blockchain technology. The definition given by PWC is: “A Blockchain is a distributed, decentralized transaction ledger, saved by each node in the network, which is owned, maintained and updated by each node. It’s a peer-to-peer system and no central authority manages the flow.” Blockchain technology is based on three principles:

  1. Fault tolerant
    The system is still able to perform it’s tasks if one or more components fail.
  2. Byzantine fault tolerant
    The system is still able to perform it’s tasks if one or more malicious component(s) give conflicting information.
  3. Consensus algorithm
    An algorithm developed to reach consensus about every transaction that is done within the blockchain.

The above principles result in a system in which all participants in the chain can perform transactions with each other, without having to worry about trusting the other party. Every participant knows that if a transaction is accepted into the chain, this transaction is free of errors and is accepted by everyone.

More than currency transactions
At the moment these principles are only being used in the Bitcoin technology. Therefore, when we speak of transactions you automatically think about a currency transaction. However, in the Blockchain a transaction can be of any kind. For instance, think about buying a house. Regulations require a notary to verify the transaction between the old house owner and the new one. With Blockchain technology the transaction can be done in the shared ledger and is verified by everyone. The trusted third parties we now know (e.g. governments, notaries, accountants, banks) will become history for storing our data and processing our transactions.
