Andreas Antonopoulos Speech Heralded as ”2019’s State of the Crypto Industry Address”

Goodreads helps you follow your favorite authors. Be the first to learn about new releases! Follow Author. Andreas M. When you have programmable money, the possibilities are truly endless. We can take many of the basic concepts of the current system that depend on legal contracts, and we can convert these into algorithmic contracts, into mathematical transactions that can be enforced on the bitcoin network.

If I choose to send value from one part of the network to another, it is peer-to-peer with no one in between. If I invent a new form of money, I can deploy it to the entire world and invite others to come and join me. Bitcoin is not just money for the internet. Bitcoin is the internet of money. Currency is only the first application. If you grasp that, you can look beyond the price, you can look beyond the volatility, you can look beyond the fad.

At its core, bitcoin is a revolutionary technology that will change the world forever. Antonopoulos, The Internet of Money. There are almost currencies controlled by central banks and governments, but there is only one mathematical currency today, and that is bitcoin. We are going to build more of them. Cryptographic currencies are going to be a mainstay of our financial future.

They are going to be a part of the future of this planet because they have been invented. You cannot un-invent this technology. You cannot turn this omelette back into eggs. Talk walks. It is the opposite of surveillance. Surveillance means to look from above; sousveillance means to look from below. In their dream of nation-states controlling all of our financial futures, they made one major miscalculation. When the panopticon turns around? When crimes committed in the names of states and powerful corporations are vulnerable to hackers and whistleblowers and leakers?

When everything eventually comes out? We have a great advantage because the natural balance of the system is one in which individuals can have privacy but the powerful cannot have secrecy anymore. And that means that if you want to build a new application on top of bitcoin, you can upgrade the devices and you can build an application.

That is the power of innovation on the internet. And that means bitcoin is not a specific financial network. It is the first transnational economy, and it needs a transnational currency. An invention that changes the oldest technology we have in civilization. That changes it radically and disruptively by changing the fundamental architecture into one where every participant is equal. Where transaction has no state or context other than obeying the consensus rules of the network that no one controls.

Where your money is yours. You control it absolutely through the application of digital signatures, and no one can censor it, no one can seize it, no one can freeze it. No one can tell you what to do or what not to do with your money. It is a system of money that is simultaneously, absolutely transnational and borderless.

Rather, deflation is associated with a collapse in demand because that is the only example of deflation we have to study. I really like the idea of a network-centric money. A network that allows you to replace trust in institutions, trust in hierarchies, with trust on the network. They operate in cash-based societies with very little access to international resources. It is a haven for pedophiles, terrorists, drug dealers, and criminals. How many of you in this room have bitcoin?

How many of you in this room are terrorists, pedophiles, drug dealers or criminals? In the blockchain, the most recent few blocks might be revised if there is a chain recalculation due to a fork. The top six blocks are like a few inches of topsoil.

But once you go more deeply into the blockchain, beyond six blocks, blocks are less and less likely to change. What requires the least infrastructure investment? What requires the least density of users and yet provides a viable solution to a real problem?

The Blockchain and Proof-of-Work Why is bitcoin immutable? What gives bitcoin the characteristics of immutability? The first answer that comes to mind for most people is "the blockchain. In security we call that "tamper-evident": if you change it, it is evident. We call it "tamper-proof": something that cannot be tampered with. There are other bitcoin blockchains that are used for testing purposes: at this time testnet, segnet, and regtest.

The testnet is a fully featured live P2P network, with wallets, test bitcoins testnet coins , mining, and all the other features of mainnet.

There are really only two differences: testnet coins are meant to be worthless and mining difficulty should be low enough that anyone can mine testnet coins relatively easily keeping them worthless. This protects both the developers from monetary losses due to bugs and the network from unintended behavior due to bugs. This creates a massive incentive for hackers. There are another 4 billion people who have very limited access to banking. The people who are currently cut off from international banking.

What do you think happens when you suddenly are able to turn a simple text-messaging phone in the middle of a rural area in Nigeria, connected to a solar panel, into a bank terminal?

Into a Western Union remittance terminal? A stock market? An IPO engine? At first, nothing, but give it a few years. That phone gives them weather reports, grain prices at the local market, and connects them to the world. What happens when that phone becomes a bank? Because with bitcoin, it can be a bank. Only now we have the internet, and so the rate of exponential growth has already started. The innovation is growing at an astonishing rate.

Do not listen to the people who tell you that bitcoin is just for pornographers, terrorists, drug dealers, and gamblers. Remember that they said the exact same thing about the internet. But when 2 or 3 million people got online, we found out that they are not interested in those things—they are interested in sharing cat videos, and now we have an internet of a billion cat videos.

Lightning Network ‘Really Does’ Solve Bitcoin Scaling: Andreas Antonopoulos

Andreas Antonopoulos has one word of advice for anyone working in blockchain -- privacy. If so, how robust can we make it? Andreas, whose mission is to educate the world about bitcoin and open blockchains and reveal their historical, technological and socio-economic impact, urging everyone to prioritize protecting privacy. He warned that society is straining at the seams and institutions threatened with change resort to lashing out. And two - in the process of those institutions breaking down, they become vindictive and rather vicious against anything they see as a threat to their power.

'One Network, Many Chains' – The Case for Blockchain Interoperability

The biggest buzzword in the crypto space today — DeFi, short for decentralized finance — has made finance cool again. Apart from making financial products decentralized and easily accessible to users of all stature, DeFi platforms such as MakerDAO also offer users the option to generate passive income on their crypto holdings, including Bitcoin BTC. DeFi protocols based on the Ethereum blockchain make this possible by offering attractive interest rates on the lent BTC. Antonopoulos explained that through DeFi, one can put their crypto holdings to productive use. However, he cautioned that putting capital to such work carries risks as well. For the uninitiated, Dai is a stablecoin pegged to the U.

To say it is not possible ever because it is not possible today is to misunderstand how engineering works. As Bitcoinist reported Friday, pro-Bitcoin responses took Bitcoin Cash supporters to task over such criticisms, noting that even in its experimental phase, the Lightning Network can already process millions of transactions per second. It allows us to change the dimensions of Bitcoin; it allows us to reduce the granularity of payments, not just down to millibits but down to satoshis and even sub-satoshi amounts… and do that all on the scale of millisecond round trips. Other providers are set to follow, joining a growing roster of businesses including Bitrefill and Living Room of Satoshi. Let us know in the comments section below!
