The necessary steps to mature out of infancy
Hi! Good morning everyone! I am so excited to be here.
So this conference was called the Bitcoin conference a couple of years ago and now it's the blockchain conference. Next year it's going to be the distributed legder technology (DLT), and then after that is going to be the database inspired by but no longer in any way related to blockchain conference. It's an interesting progression.
Let me do a quick poll of the audience. I want to get an idea of your level of experience and familiarity with this space.
So I'm going to go back to the yesteryears of Bitcoin:
How many of you currently own Bitcoin?
Those who don't own Bitcoin, how many of you have conducted a transaction or seen a transaction happen in Bitcoin?
How many do not own any cryptocurrency of any type?
How about people who are involved with etherium and owned etherium? Dash? Monero? Zcash?
How many own blockchain how many have used blockchain in a transaction or in any way other than the five things I mentioned previously?
So break down for you for those who can't see what the audience is doing, about sixty to seventy percent have a Bitcoin at the moment or have conducted a transaction. About thirty or forty percent with etherium, smaller minority with Dash, Monero and Zcash. Nobody owns blockchain. This is interesting. This is exciting. So let's get started.
The hype and empty promises around "blockchain"
What exactly is going on here?
Is this the greatest technological innovation and explosion of innovation since the mobile internet, or maybe even the internet itself?
Or is this the greatest load of hype ever arranged around the technology in the history of technology?
Both, and in fact that's a characteristic of advanced technologies.
I often say that where Bitcoin and the other open blockchains are today, is approximately where the internet was in 1992 in terms of technology, infrastructure, deployment. In terms of adoption patterns, this technology is approximately where the internet was in 1992. But the hype around blockchain is exactly where the hype around the internet was in 1998. You know what comes next.
There will be a shakeout when the waters recede you can tell who on the beach wasn't wearing a swimsuit. They stand there naked. It's an empty promise. This will happen in the blockchain space there is a lot a lot of bullshit being peddled to VCs, to investors, to initial coin offering (ICO) buyers, to uneducated investors. There's a lot of Ponzi schemes. There's a lot of pyramid schemes. There's a lot of empty promises. There's also a lot of business as usual, disguised as innovation. Disguised as disruptive technology.
So we're at this strange moment where the underlying technology really is, truly is massively disruptive massively innovative.
Blockchains vs. databases
The amount of research that's happening today in applied cryptography is unprecedented. We are looking at the largest civilian deployment of public key cryptography ever. Because it turns out that people only protect keys when those keys are attached to value, and nothing teaches someone security faster than having their Bitcoin on a Windows machine. [Laughter from the audience.]
Holding your own Bitcoin very quickly changes your attitude towards information security. You didn't care about your photos. Some didn't even care about your sexy photos. You didn't care about your location, the fact that everything you do was tracked. You didn't care about posting your entire life on Facebook. You use the same password password 1234 on 17 different sites. You didn't know what two factor authentication was, and then Bitcoin happened and suddenly you're on a steep learning curve and getting better every day. Now you're telling your friends about two-factor authentication and you're horrified to remember how you used to practice security. Because storing value has this unique ability to focus your mind on the aspects of security that matters.
So this technology is driving this groundswell of security awareness. It's driving the most incredible research and applied cryptography we've ever seen. Some of you are probably quite technical, you're involved in computer science, you've seen what's happening here. Nobody thought that we would be doing applied Schnorr signatures. Nobody thought we'd be looking at advanced elliptic curve applications. Nobody thought we'd be doing things like ring signatures and range proofs for confidential transactions. The state of anonymity and privacy is advancing rapidly. We're building a whole new world in terms of cryptography, and this is applied cryptography on the largest cryptographically secured network the world has ever seen.
That's not business as usual. It's highly disruptive.
Now, out of that came this fantastic saying: "blockchain is the technology behind bitcoin". Which is incorrect, blockchain is one of the four foundational technologies behind bitcoin and it can't stand alone. But that hasn't stopped people from trying to sell it. Blockchain is Bitcoin with a haircut in a suit that you parade in front of your board. It's the ability to deliver a sanitized, clean, comfortable version of Bitcoin to people who are too terrified of actually disruptive technology. And so you get into this very strange world where the words no longer mean anything.
Can you define blockchain for me? I think a few people in this room could probably define blockchain, but the real challenge would be: can you define blockchain in such a way that i can do search and replace with the word database and still make that sentence work? Because that's the challenge: if what you're doing is a database with signatures it's not interesting. It's boring.
The essence of Bitcoin: revolutionizing trust
What is the essence of bitcoin? It's not blockchain. The essence of bitcoin is the ability to operate in a decentralized way without having to trust anyone. The essence of bitcoin is to be able to use software to authoritatively, independently, without appeal to authority, verify everything yourself.
You don't trust the other nodes you're talking to. You assume they're lying you. You don't trust the miners, you don't trust the people creating the transactions. You don't trust anything other than the outcome of your own verification and validation, and through that you end up trusting in something more important: the network effect.
Bitcoin introduced the concept of decentralized security through computation and this has not yet sunk in. What bitcoin does, is it allows you to replace a security model that is based around concentric circles of access and control with an institution in the center with a security model that is inside out. Open and accessible to everyone. A security model that is based on market forces and game theory. It is the first market-based security model where a series of incentives and punishments ensure that the ultimate result is you can trust the platform itself as a neutral arbiter that is not controlled by anyone. Without third parties, without intermediaries.
Bitcoin revolutionizes trust.
Open blockchains are the only ones that matter
Now, it's difficult to have that conversation if you only focus on Bitcoin, and arguably a lot of people have said: "but it's not just about currency what about the other applications" and "it's not just about Bitcoin what about the other blockchains?", and so in that sense the term blockchain means something. But only if you define it very very narrowly. I use the qualifier open to talk about open blockchain.
What I'm interested in is the applications of this technology that enable you to run a decentralized, trustless system that does not rely on anyone as an intermediary of trust. Because that is the disruption here. That is the essence of this technology.
That essence is seen in other systems. Etherium exhibits it for the application of smart contracts. But those smart contracts only work if you don't have to trust anyone to execute the smart contract correctly. And you can only trust that that's going to happen if everyone can participate in an open manner and verify each other. If access to the underlying consensus algorithm in mining is open to everyone. And so out of these characteristics come power of these blockchain technologies.
Open. That's the key word.
Borderless. There are no borders transnational this is no longer about nation-states this is about network centric trust without third parties the network is the trusted party and only if you verify everything.
Neutral, because it isn't serving the goals of any one organization or institution it follows the consensus rules neutrally everyone follows the consensus rules neutrally. There is no such thing as a good transaction or a bad transaction, a valuable transaction or spam transaction, an authorized transaction or an unauthorized transaction, a legal transaction or an illegal transaction. In these systems, there is only a valid or an invalid transaction based on the consensus rules and it doesn't matter who the sender is, who the recipient is, or what the value or asset or smart contract that's being executed is: neutrality. Radical neutrality.
Censorship resistance and other important characteristics
And of course censorship resistance. The ability to ensure that in order for the system to be open and borderless and transnational and neutral it must be able to defend these properties by making it impossible for any actor or even several colluding actors from censoring, disrupting, blacklisting, restricting, seizing, freezing transactions, Users, countries from participating in this network.
Those are the important characteristics of these new open decentralized systems of trust that do not depend on institutions.
Criteria: blockchain or bullshit?
So what I'd like to equip you with is a set of criteria to understand when you are being presented with something, perhaps to invest, or to be employed, or to engage in some way. And it calls itself a blockchain or a distributed ledger or one of these other names that are coming out.
How can you tell? Blockchain or bullshit? They both start with a 'b', what's the difference? If you can replace the word blockchain with database and the brochure reads the same, it's business as usual. It's not decentralized, it's not borderless, neutral, censorship resistance, open. It re-establishes trust and intermediaries. It's just the database and that is not disruptive.
The idea we're going to take this technology and use it to improve the operating margins of centralized institutions of trust so that they can continue business as usual? I'd say it's abhorrent, but that's a strong word. It's just boring. Really, really, boring. No one got into this in order to make a few billions for a financial services clearinghouse. And if you did, I'm really sorry -- that's boring.
Fundamentally changing the allocation of trust
What's really exciting is the possibility of fundamentally changing the way we allocate trust on this planet. Opening up the ability to collaborate, transact, engage, on a global level with everyone. Simply by means of downloading an application, you can become part of a giant platform of trust that doesn't care who you are, where you came from. That doesn't require permission to participate or innovate. Where a 12 year old JavaScript programmer has the same influence and power as JPMorgan Chase. More, in fact, because they're doing open source and feeding into a community of collaboration that is creating a tsunami of innovation.
Permissioned "distributed ledgers" are boring & insecure
Taking this technology, and using it to strengthen the same centralized institutions so that they can improve their bottom line is boring. That is not what blockchain is, that's just the database and it doesn't change anything. In fact there are some rather disturbing possibilities in this model.
Let's think about it for a second.
The most commonly expressed application for these new distributed ledger technologies is to replace the function of a centralized clearinghouse with a consortium of N participants where N is 2, 3, 4, 5, 10. Known permissions, controlled participants who will assemble transactions and sign them rather than compete through market forces in a security model like Bitcoin. We discard currency as the underlying mechanism for building market based security. We discard proof of work as "wasteful," because all it allows you to do is decentralized, secure, neutral, censorship resistance blockchain. And we trust 5 named parties to sign transactions.
At that point, they don't need to assemble these transactions in blocks. They can just sign the individual transactions they don't need to chain them together, because absent proof of work and a system of currency incentives, rewriting that is easy. There's no immutability, so it's not a blockchain anymore because there's no blocks and there's no chain.
Now that's at a technical level, but let's look at the more important level. What do you achieve by replacing a clearinghouse with a consortium of players?
You know, there's something unique a clearinghouse does. If you understand the role of a clearinghouse, one of its most important functions is that it is not a participant in the market: it has no skin in the game. The New York Stock Exchange is not an active trader. that's not an accident. That's called separation of concerns. The clearinghouse is an independent party with oversight that is not a market participant. If you take that party out and replace it with five banks -- all of which have skin in the game -- how do you run a consensus algorithm when the incentives to cheat, front-run, manipulate the market, and break the consensus rules -- even adversarily against the other four parties -- are so high. There's no incentive to keep the consensus rules. All you're doing is you're saying: "trust us, we're in a consortium."
Trust us? These five banks?
Where were you in 2008? Where were you when Lehman was fixed? Where were you when the gold markets were fixed? Where were you when front-running and high-frequency trading was creating these monsters of crony capitalism?
Trust us? Hell no!
Removing the clearinghouse and replacing it with -- what's the word, it's not consortium -- cartel, that's the word. With a cartel of the same market makers who have manipulated and compromised every market in history, and doing that in a way that closes this from transparency. That's not a recipe for efficiency, immutability, security, transparency. That's not a blockchain, that's a bullshit. It's a very profitable bullshit. It requires you to have confidence in the game -- a con game, as it's known.
Be careful what you evaluate when you see these technologies taking something whose fundamental purpose is to remove trusted intermediaries and create an open, borderless, neutral system. And turning it into a tool for a bunch of untrustworthy trusted parties to manipulate markets, is going to be a disaster. And they're going to do it.
Hey Wall Street, Anonymous is coming for your keys
I have some consolation in the fact that their keys will leak. Because when you centralize a system, you have to keep the security of those five keys. And none of them have ever managed to do that. All of the companies involved in this brave new business-as-usual space have been hacked, breached, leaked, whistle blown a dozen times. They can't keep information secure. No one can!
The whole point of a decentralized blockchain is you don't keep the information secure -- you spread it out so thin there's no place to attack it directly. That's what makes it secure.
So what happens when you concentrate it among five participants? I can't wait until the Anonymous WikiLeaks collaborative dump of the titans of Wall Street and their ledger of every transaction they've ever done. I can't wait. it's going to be so much fun. And it is going to happen. You cannot secure these things.
Promising opportunities, solving the unsolvable problems
So does that mean there's nothing there? No, again we go back to the other side. There is an incredibly promising technology, and that technology is based on an architecture of openness. People are examining this market and they're grasping and reaching out in darkness. When you have a brand new disruptive technology, you can't see the margins. It's like stumbling around a dark room: somewhere in there is a billion-dollar company. Somewhere in there is an opportunity, and you have to figure out what market exists that will create opportunity that will change the world. That will have an impact on humanity.
Entrepreneurs look at other people's problems and see them as opportunities. When journalists in 1997 were writing about the imminent failure of the internet because of the impossibility of finding anything, Larry Page and Sergey Brin were finding stuff. And building a multi-billion dollar empire on solving the unsolvable problem of search.
There are seemingly unsolvable problems in the open, decentralized, public, transparent, neutral, censorship resistant, global, trustless, network platform that is the blockchain. And these other blockchains: Bitcoin, Etherium, and the many other systems that are gradually trying to find their niche.
The 3 elements to success in this industry
Where are those markets? There are three elements to success in this industry.
The first one is identifying a viable market right you've got to stumble in the dark and find something useful. And very often the people stumbling in the dark, they don't find anything useful. In 1997 Petco was building a online commerce empire for pet supplies. It was too early. The market didn't exist. Web grocer, Webvan, was delivering groceries to homes in San Francisco. Failed miserably. Was that the right market? Maybe, but it was the wrong time.
So that's the second important element: right timing. You can identify something that at some point will be enormous, but you're off by a decade.
And then the most important factor: sequencing. The prerequisites. Why did Facebook not happen in 1992? You didn't have enough density of adoption. You didn't have mobile devices that were permanently connected. You didn't even have home-based internet that was permanently on. You didn't have a dense social network in order to engage with the people you knew, because the people you knew barely had email or didn't have email.
So you can't build a system of complexity that depends on many-to-many interaction and high density when you're still doing applications that are one-to-one with low density. It's like trying to fuse hydrogen directly into carbon -- can't do that. You've got helium, lithium, beryllium. You got a long way to go keep smashing things together before you get enough density. That you can start doing interesting things in organic chemistry, to use an example from science.
Bottom line is: you can't do advanced real estates, title applications, voting on the blockchain, retail markets. You can't do consumer-to-consumer dense markets. You can't do point of sale retail with these systems yet. You can't do most of the things yet. There might be very interesting markets. And the reason you can't do them is because there's not enough liquidity there's not enough users. There is not enough adoption, the user interfaces are terrible, the applications are still at their infant stage. That doesn't mean these things can't happen. It just means they're not happening this year.
The necessary steps to mature out of infancy
We're going to see this play out. In order for people to have the trust to put the title of their home on this blockchain, it has to be able to secure not billions, but trillions of dollars in assets. And in order to be able to secure trillions of dollars in assets, it has to have liquidity and infrastructure. It has to have broad adoption. You're not going to get adoption on a transaction that most people do twice in their lifetime when you can't even get them to use it for transactions they do every day.
We're not going to be doing digital identity so that everyone can have a bank account. Because it takes a long time until you have adequate adoption. For the first 15 years of the internet, the application was email. And not until everybody had it, had to have it, needed it for work did we see the second layer emerge. Because that created the density of adoption. And currency is the email of blockchains. Payments are the fundamental infrastructure that will enable density of adoption.
It's very, very enticing to say this is about more than money. It is -- absolutely -- in the long term. The vision of this technology is far beyond money, but you can't build that unless you first build the money part. That's what creates the security. That's what creates the velocity, the liquidity, the infrastructure. That's what funds the entire ecosystem. And in the end, when we do deliver -- perhaps digital identity -- to people, it won't be so they can open a bank account. Because this isn't about banking the unbanked. it's about de-banking all of us.
Thank you. [Applause]
I have lately followed Andreas on youtube. Very interesting talk about the blockchain. Blockchain technology is just amassing, and I think it is here to stay.
