Ignore Bitcoin’s challenges. In this interview, Don Tapscott explains why blockchains, the technology underpinning the cryptocurrency, have the potential to revolutionize the world economy.
Outline:
Blockchains are used by many different people and organizations to help them do things more efficiently or securely. They can be used as a digital currency (like bitcoin) or they can be used to manage other types of data. For example, if you are trying to sell something online, you might use blockchain technology to make sure that your money gets transferred directly to the buyer without any middlemen getting involved. Or if you want to make sure that someone who is making a movie doesn't copy off another person's work, you could use blockchain technology to make certain that the original version of the film stays safe. This technology is very secure because there is always a record of what happened when. You can see every transaction that occurred and it is easy to verify whether the information was correct. Because the records are public, everyone can check them. So, in theory, we should never have to worry about fraud again.
The old media is centralized. Only one source controls everything. People are passive recipients who watch television. The new media is decentralized. Many sources control everything. Everyone is a participant. We have this great asset of information that was created by us. But we don't get to keep it. Companies or governments use it to spy on people and undermine our privacy.There is a new internet called Bitcoin. It enables people to buy things online without having to pay any middlemen. People use this system to make payments to each other. It is also used by criminals to launder money and move it around the world. Bitcoin is a decentralized currency meaning that no single person or organization controls it.Satoshi Nakamoto invented bitcoin. He was a mysterious person who lived in Japan. He created the bitcoin protocol and released it into the world. Satoshi Nakamoto is still alive today.
Blockchain is a distributed database that records every transaction made by everyone. It's a peer to peer network. Anyone can change the underlying code and see what's happening. It's open source, so anyone could see what's going on. It's truly peer to peer; there's no need for powerful intermediaries to authentify or settle transactions. It uses modern cryptographic technology, so if we have an open, distributed database that can store the fact that we've done this transaction, what other data could it store? Well, it could store any kind of data, not just who paid who but also who married who or who owns what land. In the case of IoT, we'll need a blockchain-based settlement system to handle billions of transactions per second between smart devices. Banks won't be able to settle trillions upon trillions of real time transactions between things.Blockchain is a technology that allows people to transact online without having to know the identity of the person or entity that they're transacting with. It's a decentralized network that uses cryptography to secure transactions. The blockchain is the underlying technology behind cryptocurrencies such as bitcoin.Blockchain is the new revolution in computer science, and it's the most important invention since the internet. The blockchain is used to store information securely, and it's also used as a payment mechanism. The blockchain solves the double-spend problem by using smart contracts. Smart contracts are programs that run automatically when certain conditions occur. The blockchain is decentralized, meaning there isn't any central authority controlling transactions. This makes it very secure because there is no single point of failure. The bitcoin blockchain uses proof of work (POW) to verify transactions. POW requires miners to solve complex mathematical problems. Miners compete for rewards, which are given out every 10 minutes. The reward is halved every four years until it reaches zero. In addition to solving math puzzles, miners must maintain the integrity of the network. To do this, they must follow strict rules regarding what software they can use and how much electricity they consume.Each miner is motivated to be first to find the truth. Once you find the truth, you get paid some Bitcoin. You must solve a complex mathematical problem to get paid. When you do, you get paid more than any other person. Blockchain technology makes this possible by linking blocks together. The chain is run on many computers. Hacking this system requires massive computing power.Bitcoin is a digital currency that can be used to buy things online. It is also used as a store of value. There have been many problems with Bitcoin, but it doesn't matter because it isn't an investment. It's more like a commodity.Blockchain is a decentralized database that records every transaction made by users. This means that blockchain isn't controlled by any single organization or government. Instead, data is stored across many computers all over the world, making it impossible to change or tamper with.
Blockchain revolution is disrupting the finance sector. Money moving, storing, lending, trading, attesting, accounting, etc., can all be done using blockchain technology. This technology allows us to share information freely among users without having to trust each other. We can also store data securely. Blockchain revolution creates a more prosperous world where everyone gets to participate in the value they create. Music industry is a disaster, atleast from the point of view od the musicians. They used too have most of the value take by the big labels. Nowadays, the technology companies take most of the value. Musicians are left with crumbs. What if the new musical industry is a distributed app on the blockchain, where I, as an artist, can post my songs onto the blockchain with a contract specifying how it is going to be used.Maybe as a recording artist posting music on a blockchain music streaming service, I'll say, 'You listen to the music. It's free. You want to upload it into your movie? It's going to cost you this amount, and here's how that works. You upload it into the movie, the smart contracts pay me.' Or how about using it as a ringtone? There's the smart contract for that! This isn't a pipe dream. Imogene Heap, who's a brilliant singer-song writer in the UK, a best-selling record artist, has now been involved in creating Mycelia, which is working with an amazing company named Consensus Systems, which is all around the world, Blockchain Developers, using the Ethereum Platform; Ethereum is one blockchain.'
Futurists are people who try to predict what might happen in the future. In this case, the futurist is trying to make predictions about the future. He says that there are 10 things that could go wrong when using AI. First he mentions how much energy is used to run these computers. Then he talks about how AI will replace human workers. Finally, he talks about how AI could be the end of many jobs.Blockchain technology is a very important innovation. However, it is still immature and lacks proper governance. In addition, due to its decentralized nature, it is vulnerable to attacks and manipulation.A lot of smart people are investing in startups. There are lots of new companies being created by brilliant people. Some of them are really cool ideas. Maybe some of them will be successful. But there are also a lot of dumb ideas. And there are also a lot scams. So many people are trying to make money off the internet. I think it's a great time to invest in startups.Most people in developing countries don't have access to banks or money transfer services. This forces them to use informal methods such as bartering goods or paying with cash. A dictator takes over and decides to change this by bringing everyone into the global banking system. He issues new ID cards and allows people to pay for things using these cards. People can now buy things online and send money to friends and family around the world.A world where foreign aid goes directly to the beneficiary under smart contracts. Rather than a car service aggregation, why couldn't we have a distributed app that manages all these vehicles. And handle everything from reputation to payments. Ultimately, they'll be autonomous vehicles moving around or blockchain Airbnb? This is about the value going to creators of value rather than capturing it by powerful forces.Identity is the foundation of freedom. We need to protect this right. Identity management should be done responsibly.We've been unable to do that so far. I'm compelled most by the power this opportunity. I‘ve been at this 35 year, writing about the digital era. I’ve never seen a technology that I though had greater potential for humanity, than blockchain.
