Blockchain Explained

Blockchain is a distributed and immutable ledger allowing you to track anything, including tangible or intangible goods. This enables users or organizations to digitally and securely record entries, that are in-turn endorsed and secured by a community of users.

Sai Vennam from IBM Cloud takes a deep dive into blockchain technology and covers everything from smart contracts to permissioned and permissionless blockchains

What is Blockchain?

Is Blockchain safe? Is it the future? Can you put your money in it and expect a return? What should you do when someone offers you a chance to invest in Bitcoin or other cryptocurrencies? Blockchain is the future but it’s already unfolding before our very eyes today.

The Case for Decentralization

Chris Dixon, General Partner at Andreessen Horowitz, talks about the history of computing, blockchain, crypto, smart contracts and the case for decentralization.

The killer apps for blockchain have yet to be developed. Blockchain is transparent and open source.

We’re entering a golden era of creativity via better trust properties and community owned and operated digital services.

Our Neuralink Future

Elon Musk’s newer company “Neuralink” just demoed the brain device they’ve been working on the past 2 years during a live stream event. I’ve been waiting a long time to get a glimpse of the hardware, software, and intentions they have as they build this technology and the event was satisfying, thought provoking, and humbling. I’m going to review my impressions of the event, explain how the device works in technical detail, then make a few predictions of what it’s going to be used for in the future. It’s an exciting time to be alive, and although there are dangers involved, I have faith that we can learn from our mistakes and avoid having this tool be used for exploitation like social networks have been used for.

What is a dApp? Decentralized Application on the Blockchain

dApp is the abbreviated term for a decentralized application. Just as any developer can build apps for the App Store on Apple’s IOS operating system, developers can (also) build on top of Ethereum’s blockchain infrastructure. To the end user, a dApp might not look and feel any different than other apps you use today. However, dApps are powered by the blockchain; and this makes them different – and perhaps.. far superior.

Learning Dexterity

OpenAI is a non-profit AI research company, discovering and enacting the path to safe artificial general intelligence. They’ve trained a human-like robot hand to manipulate physical objects with unprecedented dexterity.

Their system, called Dactyl, is trained entirely in simulation and transfers its knowledge to reality, adapting to real-world physics.

Dactyl learns from scratch using the same general-purpose reinforcement learning algorithm and code as OpenAI Five. Their results show that it’s possible to train agents in simulation and have them solve real-world tasks, without physically-accurate modeling of the world.
