Cryptocurrencies constitute just one application of blockchain. But the technology has the potential to transform how we store and secure all kinds of data.
The future will be decentralized | Charles Hoskinson | TEDxBermuda
This talk was given at a local TEDx event, produced independently of the TED Conferences. Tech entrepreneur and mathematician Charles Hoskinson says Bitcoin-related technology is about to revolutionise property rights, banking, remote education, private law and crowd-funding for the developing world.
Charles Hoskinson is Chief Executive Officer at Thanatos Holdings, Director at The Bitcoin Education Project, and President at the Hoskinson Content Group LLC.
Charles is a Colorado-based technology entrepreneur and mathematician. He attended University of Colorado, Boulder to study analytic number theory in graduate school before moving into cryptography and social network theory.
His professional experience includes work with NoSQL and Bigdata using MongoDB and Hadoop for several data mining projects involving crowdsource research and also development of web spiders. He is the author of several white papers on the design and deployment of low bandwidth prolog based semantical web scraping bots as well as analysis of metamorphic computer viruses through a case study on Zmist.
NFTs and the Metaverse: The internet enters a new phase
The metaverse is typically used to describe the concept of a future iteration of the Internet, made up of persistent, shared, 3D virtual spaces linked into a perceived virtual universe.The metaverse in a broader sense may not only refer to virtual worlds, but Internet as a whole, including the entire spectrum of augmented reality.
This is a Game Changer for Blockchain
Twitter has unveiled an in-development tool that will enable users to display a verified nonfungible token (NFT) as their profile picture. The bigger story could be the growth and acceptance of this kind of technology for identity verification across the web.
DeSo Blockchain Wants to Decentralize Social Media
DeSo Creator Nader Al-Naji speaks with Caroline Hyde about building an NFT-based social network, how to use the blockchain to reinvent community platforms, and why a DeFi future could circumvent the power of Facebook.
What are Oracles in Crypto? (Animated)
Oracles are a trusted third party source of information that give real-world data to a blockchain.
Basic Blockchain EXPLAINED – Scott Stornetta, Creator of Blockchain Technology
How would you explain Blockchain in simple terms? Are blockchains anonymous? Can you trace a blockchain transition? Is blockchain and bitcoin the same? Let’s find out.
Welcome to Explain Like I’m 5, where we’re making it easy for you, explain crypto concepts in simple terms and answer the questions we’ve all been asked by friends and family about crypto. In this episode of the show, Jessica is joined by Scott Stornetta is the blockchain co-inventor quoted in the Bitcoin whitepaper written by Satoshi Nakamoto, who created the first cryptocurrency in 2009.
CODE IS LAW? Smart Contracts Explained (Ethereum, DeFi)
Have you ever heard the expression “code is law” where technology is used to enforce rules? In that case, do we even need lawyers? Or maybe we can live in a fully automated world where code dictates what we can and cannot do. With the current development of smart contracts, this futuristic scenario may be closer than we think.
A smart contract is a piece of code that can be executed automatically and in a deterministic way. The smart contract code is usually stored and executed on the blockchain to make it trustless and secure. Smart contracts also have capabilities of receiving, storing and sending funds and even calling other smart contracts. They follow if-then semantics which makes them fairly easy to program.
Smart contracts aim at removing the human factor from decision making. The human factor is often proven to be the most error-prone and unreliable element of the standard, traditional contracts.
Ethereum is a good example of a blockchain that supports smart contracts and make it possible for a programmer to implement their own smart contracts. A smart contract can be written in a programming language called Solidity which was created specifically for that purpose. In Ethereum, all the deployed smart contracts are immutable. This means that once deployed they cannot be modified which creates certain risks that we’re going to discuss later. Smart contracts on Ethereum are also decentralized which means there is no single machine controlling the contract. In fact, all the nodes of the Ethereum network store the same contract with exactly the same state.
An Introduction To DApps & Blockchain Technology
Welcome back to another video! In this video, we’ll be going over blockchain technology and DApps, a.k.a decentralized applications. This is going to be more of a high-level introduction to DApps and using blockchain technology to create DApps. This topic will focus on the development side of cryptocurrency rather than the investment side.
What is a Blockchain Oracle? What is the Oracle Problem? | Chainlink Engineering Tutorials
Understand what Blockchain Oracles are, and the challenges that they face in the Oracle Problem. Understand why your smart contracts and blockchain platforms can’t themselves make API calls as part of their consensus. Then, understand how Chainlink solves each one of these.
Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments. Chainlink is critical to connecting the blockchain ecosystem to the rest of the world.
