Substrate is the backbone that powers Polkadot, a next generation, heterogeneous, multi-chain network. Most of the blockchains in the Polkadot ecosystem are also built on Substrate. The Polkadot Network was launched in May of 2020.... Substrate is a modular framework that enables you to create purpose-built blockchains by composing custom or pre-built components... Substrate's modular design means you can reuse battle-tested libraries while building the custom components that matter most... Use Substrate's FRAME runtime system to build secure, scalable blockchain logic... Create rich user experiences for any Substrate-based chain with Polkadot-JS. https://substrate.dev/ (more)

Polkadot is a sharded heterogeneous multi-chain architecture which enables external networks as well as customised layer one "parachains" to communicate, creating an interconnected internet of blockchains.[citation needed] The cryptocurrency uses proof of stake.[1] The protocol was created by the Ethereum co-founder Gavin Wood[2] and is developed by Parity Technologies. https://en.wikipedia.org/wiki/Polkadot_(cryptocurrency) (more)

Rob Behnke: How Polkadot's Parachain Model Reimagines Blockchain Security. Blockchains can be attacked in a variety of different ways. However, the most famous potential blockchain attack is the 51% attack against Proof of Work (PoW) blockchains. (more)

Polkadot passes the $140M mark for its fund-raise to link private and public blockchains. In effect, Polkadot is the interchange and translator between multiple blockchains which creative people developing on the Ethereum blockchain have been looking for in order to build a wealth new projects and infrastructure.

Gavin Wood: The Launch of Parachains. Now, phase five, the final phase in the launch of Polkadot is beginning. Polkadot is a heterogeneous scalable multichain. In its brief history, Polkadot has demonstrated a highly decentralised and inclusive staking system (anyone with as little as 1 DOT may take part in Polkadot’s staking system and be rewarded), seamless upgrades to its core logic and open, functional governance. However it has so far existed only as a single chain in isolation. With the launch of parachain functionality, this is about to change and the final vision of a heterogeneously sharded system is about to become reality. (more)

By Polkadot: A Deep Dive into Polkadot. Polkadot is a next-generation blockchain and layer-0 protocol that unites multiple specialized blockchains into a unified, scalable network. Polkadot was designed as part of a broad vision for a fair, secure and resilient web that protects user interests by design (Web 3.0). (more)

Gavin Wood: Polkadot, Substrate, and Ethereum. Parity is as committed as ever to supporting and bridging “Ethereum”, however it is intended, into Substrate and Polkadot. While we are creating Substrate and its associated smart-contract infrastructure to be the world’s most powerful and joyous framework for creating new blockchains and dApps, we absolutely understand that there are many who enjoy their home in Ethereum ecosystem (more)

Janet Woodcock (born August 29, 1948) is an American physician who is currently serving as the acting Commissioner of the U.S. Food and Drug Administration (FDA).[2] She joined the FDA in 1986, and has held a number of senior leadership positions there including terms as the Director of Center for Drug Evaluation and Research (CDER) from 1994 to 2004 and 2007–2021.[3]... On January 27, 2021 a coalition of 28 public health groups and opioid organizations sent a letter to the Biden Administration regarding Woodcock's position as Acting Commissioner of the FDA. The letter said in part that "as the Director of the FDA’s Center for Drug Evaluation and Research (CDER) for more than 25 years, Dr. Woodcock presided over one of the worst regulatory agency failures in U.S. history."[35] Examples of improper opioid decisions mentioned in the letter include "approving Opana without adequate evidence of safety or long-term efficacy, approving Zohydro despite a vote of 11-2 against approval by a scientific advisory committee, and approving promotion of OxyContin for children as young as 11 years old." https://en.wikipedia.org/wiki/Janet_Woodcock

Zvi Mowshowitz: Covid-19 7/29: You Play to Win the Game. Few things warm my heart more than playing to win the game. Few things sadden me more than observing someone not playing to win the game. Usually, that means they are playing a different game instead, whether they admit it or not, and whether or not they know it themselves. The game, from this perspective, is simply that which you are playing to win, and your revealed preferences define the game’s rules and objectives. (more)

Three weeks ago, in One Last Scare ((2021-06-17) ZviM Covid 6/17 One Last Scare), I ran the numbers and concluded that most places in America would ‘make it’ without a big scary surge from Delta variant. It’s time to look at what went wrong with that calculation, which I believe to be a failure to sufficiently integrate different parts of my model (more)
