In the 1970s, the big bull market was in gold. That was the place to be.
In the Eighties, it was Japan. In the Nineties, it was tech. And in the 2000s, it was commodities.
But what about the Tens? What has been the great bull market of this decade? US stocks, maybe? Biotech, perhaps? London property?
Nope, so far, in terms of the gains at least, it has been Bitcoin. There are people who have made over a million times their money.
And I reckon the next place to be is in one of Bitcoin’s offshoots — a technology you’ve probably never even heard of.
A Short History of Digital Cash
As you may know, I’m just finishing writing a book about Bitcoin. And, in the course of writing the final chapters, my eyes have been opened in a way that I didn’t expect.
This technology is so disruptive it is going to change everything. Money, banking, the law, accounting, social media, email, gambling, web hosting, cloud computing, stock markets - the government even. It could be as significant as the world wide web.
Before I explain what it is going to do, I need to explain what it is.
Prior to Bitcoin, there were plenty attempts at digital cash. They all failed. There was a reason.
If I send you an email, I can, if I want to, then copy and paste that email and send it to someone else. I could do the same with a picture, a document, a film — any form of digital code.
What’s to stop you doing the same with digital cash: cutting and pasting the code and spending the same money again and again? This is the problem of double spending — and it hamstrung digital cash developers for years.
Previous attempts got around the problem by having a central body log all transactions and police the network — rather as a bank does with fiat money.
But this would mean the currency was centralized — and the whole point about Bitcoin is that it is decentralized. Bitcoin’s inventor, Satoshi Nakamoto, wanted a system that did not involve trust in a central body — he wanted to have nobody in charge.
He got around the problem using a huge public database. Every bitcoin transaction is logged on the database and confirmed, and everyone can see it. Once it is confirmed, the transaction cannot be undone. Ownership of that bitcoin is transferred, and it cannot then be re-spent by the original owner.
But who maintains the database?
Anyone with a powerful enough computer can, in theory, create their own bitcoins — this is known as ‘mining’. You download the mining software and run it on your computer. As you can imagine, given the price of a Bitcoin, hundreds of computers all round the world have been set up to try and mine coins.
As the computers mine, what they are actually doing is competing to maintain the database — verifying all the transactions that have taken place. There is a race to do this every ten minutes. When the race is won, the new records are added to the database and the computer that wins is rewarded with Bitcoins. Then the next race begins.
So the system is self-reinforcing. People, acting in their own self-interest (the reward of bitcoins) are maintaining the block chain and so bringing benefit to others. It’s wonderful Ayn Rand stuff.
This database is known as the block chain.
And it is block chain technology where the next great bull market is just beginning.
Block Chain — The Root of the Next Big Bull Market
When Satoshi developed bitcoin (and by the way I think I've worked out who he is), there were three things he was working on. First, this block chain. Second, a transaction system — he wanted to see if his tokens would achieve any sort of market value without official backing. In both cases he was wildly successful.
He had a third option. But he was so concerned with making Bitcoin work that he deliberately neutered it. But now that Bitcoin is up and running, developers are enabling this third option.
It extends the block chain technology beyond a money system, into a kind of replacement for the way the Internet works today.
For example, we now have Bitmessage — a decentralized system of sending and receiving emails without Google or Hotmail or whoever the email service provider might be. So nobody can read your emails, except the person you sent it to.
You have Twister — like Twitter, but peer-to-peer and with no central body. It’s a much safer way to organize an Arab Spring or to indulge in 'excessive' free speech.
You could register ownership of financial assets and have contracts verified on a block chain. This has all sorts of implications for Wall Street, the City and share registrars and brokers. You could register car ownership. The Land Registry could even be put on a block chain (about time that lot pulled their socks up — 50% of land in the UK is still unregistered). This could transform the legal system and slash costs.
You can have peer-to-peer gambling on a block chain; prediction markets; cloud computing; hosting; reputation and identity systems (username and password systems are on their way out).
You can also take traditional apps such as YouTube, Facebook or Netflix and make all these services run in a decentralized way with no central body controlling them. Why would you want that? Well, how much of your personal data is on Facebook? Who is monitoring your YouTube viewing? And think about the copyright implications for the TV and movie industries.
It is revolutionary stuff and it is happening now. In the course of writing my book, I spoke to Charles Hoskinson of Ethereum — a company for whom Satoshi Nakamoto is actually rumored to be working. It has been dubbed ‘Bitcoin 2.0’ — combining the decentralized block chain system central to Bitcoin with a software development platform.
Says Hoskinson: “Bitcoin was an exploration of how can we build a decentralized value system, where we dis-intermediate the government and banks from the generation of money. Ethereum is extracting and saying what else can we dis-intermediate? Can we remove Dropbox from storage? Can we remove Rackspace and Amazon from hosting? Can we remove Las Vegas from gambling? Can we remove Wall Street from finance?
“And instead can we run these things in a decentralized way? We’re seeing how many other things in society we can actually decentralize… so that they’re not controlled by any one actor. We want to let people choose and program whatever disintermediation they want”.
Words like ‘block chain’ and ‘mining’ and ‘dis-intermediation’ are as alien to us now as ‘browser’, ‘website’ or ‘URL’ were 20 years ago. But in a few years they will be commonplace.
And it’s not just corporations that need to pay attention — there are huge implications for government too. If everything can be dis-intermediated and decentralized, then what does that mean for healthcare, welfare and education provision, and the bureaucratic megalith of middlemen currently involved?
What indeed will be the purpose of representative democracy?
The revolution will not be televised. It will be time stamped on the block chain. It is all very exciting.
Block chain tech. You heard it here first.
