Trust is the lifeblood of all social interactions. In an environment with high levels of trust, people can make transactions in full confidence that their counterparties are who they say they are, and will behave to both party’s satisfaction. If there is low trust in a society, the social consequences are manifold, unpredictable and often violent. People build structures and institutions that act as proxies for trust, but those structures can go wrong in ways that can become detrimental to everyday social life. For example, a bank’s network fails, leaving a transaction incomplete; a government that starts doing the opposite of what it says it will do; a website claiming to uphold free speech that starts censoring undesirable comments.
How The Internet Changed Trust
In our increasingly technologized world, society has come to see the use of electronic proxies for communication, commerce or even as a way of passing the time, as entirely normal. We have built networks that enable people to enter trusted relationships without ever having met each other. The most expansive network we have built is the internet. The internet’s most familiar app, the World Wide Web, started off as a platform that held vast amounts of information. However, there was so little going on with these early web pages that a 56k modem on a phone line was sufficient to call them up. The internet started to become more powerful and much more interactive in the mid-2000s with the arrival of e-commerce, social media and networking. It became possible for people to use the internet to transfer money and their personal information. This upgrade in the internet’s capability required a new kind of trust: trust that people’s money and personal information was safe in the hands, not of another person, but of a machine, and not just of one machine, but getting transferred between machines and sometimes across different networks.
A study by the Pew Research Center in 2017, surveyed people’s attitude to the kind of trust people had for holding money and personal information on a digital platform. The respondents answered a range of questions but here are some of the types of answers they gave:
- A combination of better technology with people allowing it to play a more prominent role in their lives will improve trust.
- Government and industry regulation tailored to the nature of the internet will improve trust.
- Trust itself will be fluid depending on the context.
- Compliance replaces trust as part of a “new normal” if users still want the fruits of the internet’s functions.
- Blockchain can improve elements of the internet but it will not be so disruptive by the time it becomes universally adopted.
- Governments and corporations have no interest in improving trust over the internet and criminal networks will undermine trust.
I have focused on money and personal information because, in the digital world, those two attributes have merged into what has become known as “digital assets.” Information has just as much value as money. Meanwhile, nefarious actors have organized themselves into networks which have become adept at attacking other networks. Such nefarious networks are just as likely to be seeking personally-identifiable information as they would be seeking money. The WannaCry virus of 2017 was one such example where the hackers were seeking digital information as well as funds.
Bitcoin As A New Trust Layer For The Internet
The internet currently has seven layers as expressed in this model below. This is the Open Systems Interconnections model (OSI).
(Source)
The model describes seven layers (from bottom to top):
- Physical layer for the transfer of raw data.
- Data link layer which secures links between networked computers or nodes.
- Network layer that controls the secure transfer of data packets from a node on one network to a node on another network (like what a VPN would do).
- Transport layer which transfers data sequences of differing lengths from one application to another.
- Session layer controls the setup of connections between computers which run logins, name lookup and logouts.
- Presentation layer arranges the data into a format that the application layer can view.
- Application layer is where the user manipulates software, such as Microsoft Office or web browsers, so that it communicates between the client and server to perform certain tasks.
It has been argued that this OSI model needs a trust layer that does not create a single point of failure — like downtime — at any stage of the user’s interaction with the internet.
This is where Bitcoin comes in. You can speak of Bitcoin the network or bitcoin the asset, but in both cases, one can argue that Bitcoin combines money and information. The Bitcoin network is a trust protocol and we see it as the essential trust layer for the internet. The Bitcoin protocol is a set of rules that govern the network and protect it from attacks, like tampering with the blockchain, double-spending or spamming the network. We consider Bitcoin as a much-needed trust layer for the internet because it is trustless. How can this be? “Trustless” means that there are no entities that users have to trust in order to get their information from one node to another and its eventual confirmation onto the network. Instead, the decentralized nature and transparency of the network is the base on which Bitcoin’s trust protocol sits. Bitcoin’s own trust protocol runs on two levels: the transaction level, where users in a transaction swap their public keys and then sign transactions with their private keys so that both users can know that the transaction was genuine; the network level where thousands of nodes and miners confirm that the transaction was not spent twice and then broadcast to the blockchain.
Proof-Of-Work For Analytics
What would be the mechanism that can make Bitcoin a viable trust layer for the internet? In our book “Trust and the Rise of Bitcoin,” we have proposed “proof-of-work for analytics,” which refers to the amount of computational effort required to audit the Bitcoin ecosystem in real time. Users, individually or in a pool, can apply this proofing by running a full node that surveils internet data about the current state of the blockchain. At the moment, there are thousands of full nodes doing just that. Proof-of-work for analytics helps to deter world governments and their corporate agencies from mass surveillance as well as abusive data mining. The greater the number of full nodes analyzing the blockchain, the more data points there will be. Proof-of-work for analytics can be applied to those areas of the internet where users’ private information is most vulnerable to mass surveillance, such as on social media. Basically, we are proposing that the Bitcoin protocol, using the proof-of-work algorithm, can provide the internet with a much-needed layer of trust.
External Factors That Impact On Trust
There are other factors that will influence the prospects of the Bitcoin protocol in improving trust in the internet. The blockchain industry, financial regulators and law enforcement agencies will have an impact on Bitcoin as a trust layer for the internet. Will their interventions assist or hinder blockchain technology in being trustworthy from the public’s point of view?
This is where we move away slightly from the Bitcoin-centric notion of trust and toward the type of trust where new users are willing to use Bitcoin not only because they trust the network to carry out the functions that the protocol promises, but also because they have assessed their trust of Bitcoin based on what they have heard from the words and actions of blockchain companies, regulators and law enforcement agencies. We need to deal with this layman’s idea of trust because the computational trust of the Bitcoin protocol becomes a non-starter if users do not have conventional trust in Bitcoin.
When we look at the blockchain industry, centralized exchanges have been the shop window for bitcoin. If something goes wrong with an exchange anywhere, be it a denial-of-service attack, funds stolen or the like, the public tends to think that the Bitcoin blockchain itself has been hacked. The mainstream news loves personalities, so, individuals such as Gerald Cotten of QuadrigaCX, Alexander Vinnik of BTC-e and Ross Ulbricht of the Silk Road dark web marketplace, have all played their part in making bitcoin look like a currency that only renegades would use. The voice of the Bitcoin community is barely heard for two reasons: The community’s information is not the public’s go-to source and the emotive explanations that come from the mainstream news media overpower the technical explanations of the Bitcoiners. Instead, it is the mainstream news media who, as we all know, have a taste for remarking, “Bitcoin is going down to zero,” or “Bitcoin is too volatile,” or “Bitcoin is used by criminals,” or most recently, “Bitcoin uses too much energy.” With that level of discourse, where is the opening into which we can introduce the concept of computational trust? Or even that the energy consumption involved in Bitcoin mining — which is low compared to other industrial practices — is the price one pays for the decentralization and transparency that Bitcoin offers?
The public sees the evolving relationship between Bitcoin and regulators. Bitcoin has come under the scrutiny of financial regulators albeit at different times, depending on the region. For instance, the Mt. Gox collapse in 2014 awakened the East Asian regulators to Bitcoin, but it took the revelations from the Panama Papers in 2016, to bring cryptocurrencies to the attention of European regulators. Financial regulators around the…
