Twitter wants an open / decentralized standard for social media

Jack Dorsey: Twitter is funding a small independent team of up to five open source architects, engineers, and designers to develop an open and decentralized standard for social media. The goal is for Twitter to ultimately be a client of this standard. Color me surprised and impressed. My first thought was, “why create something brand new when smart people have been working on open standards for a long time already?” Then I read on: For social media, we’d like this team to either find an existing decentralized standard they can help move forward, or failing that, create one from scratch. That’s the only direction we at Twitter, Inc. will provide. Verrry interesting, indeed. What do you think will come of all this?

Shell invests in Ethereum

This is a really interesting usage of blockchain technology to ensure you are really getting what you think you bought. Michael del Castillo writes on Forbes.com: The fifth-largest oil and gas company in the world, valued at $262 billion, is investing an undisclosed amount in LO3, a New York startup using a modified version of the ethereum blockchain to make it easier for individuals to buy and sell locally produced energy using the existing network of power cables. While the bitcoin blockchain lets users track the flow of value without the need of banks to audit the system, LO3’s platform, called Exergy, is designed to track the flow of energy as it is added to a shared, local energy network, giving the neighbors who purchase the energy absolute certainty it really came from a windmill, a solar panel or a gerbil running on a treadmill.

Truffle framework and decentralized Ethereum apps

We talk Tim Coulter about how Truffle (Ethereum Swiss Army knife), how he got into Ethereum and dapp development, Solidity vs JavaScript, smart contract testing, EthPM which is like npm but for Ethereum, Why decentralization? Why dapps? Basically, why rebuild the internet? And last but not least - who’s using Truffle and what have they built with it?

Why decentralization matters

Chris Dixon on Medium: Early internet protocols were technical specifications created by working groups or non-profit organizations that relied on the alignment of interests in the internet community to gain adoption. This method worked well during the very early stages of the internet but since the early 1990s very few new protocols have gained widespread adoption. Cryptonetworks fix these problems by providing economics incentives to developers, maintainers, and other network participants in the form of tokens. They are also much more technically robust. For example, they are able to keep state and do arbitrary transformations on that state, something past protocols could never do. What Chris is advocating is the protocols of the past weren’t made for the internet of the future. The next era of the internet is being built with Web 3.

Blockchains and Databases at OSCON

We went back into the archives to conversations we had around blockchains and databases at OSCON 2017. We talked with Monty Widenius (creator of MariaDB), Brian Behlendorf (Executive Director of Hyperledger), and Tague Griffith (Head of Developer Advocacy at Redis Labs). Business Source License (BSL) is there to be a bridge between closed source and open source. - Monty Widenius

Fundamental Challenges with Public Blockchains

Preethi does a great job of bringing some sanity to the (somewhat justified) hype around Ethereum and friends: blockchains have several major technical barriers that make them impractical for mainstream use today… it could be many years before trustless systems are ready for mainstream use at scale. We discussed these issues with Preethi in-depth at the tail end of The Changelog #277.

What Is a Blockchain Smart Contract?

If you’re new to or learning more about blockchain, this is a great post that breaks down the semantics of what a blockchain smart contract is and is not. Mike Bursell: The first thing to know about blockchain smart contracts is that there isn’t a contract, they aren’t smart, nor are they necessarily on a blockchain. Smart contracts could, I suppose, be smart, but for me, that means complex and able to react to unexpected or unlikely situations. I think that people call them “smart” because they’re embodied in code.

Bisq, the decentralized Bitcoin exchange

Chris Beams joins the show to talk about Bisq, the P2P decentralized Bitcoin exchange and open-source desktop application that allows you to buy and sell bitcoins in exchange for national currencies, or alternative crypto currencies. We get some background on the issues faced by crypto exchanges like CoinBase, and the now defunkt Mt. Gox. We discuss whether or not Bitcoin is a censorship resistant payment system and what it means to have anonymous transaction currency options. Bisq also has an interesting white paper about its own DAO (Decentralized Autonomous Organization) to support its contributors and we discuss that in detail at the end of the episode.
