If you missed Chris’ talk at the Hyperledger Member Summit, don’t worry! We have consolidated it into one video, where Chris walks you through the architecture and demos of blockchain-based registries. Come and learn how you can build the next enterprise blockchain use case using Git, Sawtooth, and Cardstack technology!

We are about to launch Tally on Rinkeby testnet! This will be the first part of the CARD Protocol for which we are starting this testing phase. Watch the demo by our product manager Dmitry and learn how to play around with Tally both as a customer and as a service provider. Live URL and instructions to obtain test token will be released on Discord next Monday. https://www.youtube.com/watch?v=REa9Dr1lEMU

Our engineer Jen Weber will be coding live at the BostonJS meetup today, August 1. She will present “debugging secrets of the pros, for everyone,” revealing how to write and debug complex JavaScript codebases, using specific Cardstack examples. The event is free! So, if you happen to be in Boston today, you can still RSVP on the website.

We have launched Tally on testnet! Being the metering and billing network for decentralized SaaS and the first part of the CARD Protocol, Tally is now running on the Rinkeby test network: https://staging-tally.stack.cards/ You can find the instructions for our testing phase in this article and watch the demo by our product manager Dmitry, to learn how to play around with Tally both as a customer and as a service provider.

Developers, listen up! Don’t miss our newest tech talk, where Chris explains one of the basic building blocks of Cardstack: card schema. A card schema defines what a card is and what its relationship with other cards looks like. This definition is used to build applications and allow cards to move around the whole ecosystem.

Developers, follow along with our movie list tutorial to enable editing mode for your card types! This editing tool, aka the Right Edge, is a feature of the Card SDK that allows end users to edit Cards from the browser/UI: https://youtu.be/QAzqXLZVjXA

Deep dive for developers: If you’re interested in schemas, peruse this blog post that goes with Chris’s recent tech talk. Accompanied by links to the video, it explains the concepts and design of one of Cardstack’s basic building blocks, aka “Card Schema”, which (along with Gitchain) enables cards to move around. Understanding the principle of card schemas is a crucial aspect of making the decentralized Web a reality—in the same scrumptious UI quality you expect from today’s centralized apps.

Tally is now running on Rinkeby testnet! Feel free to play around with our metering & billing network for dSaaS, taking the role of a customer and/or service provider (note: you don't have to be a developer to try this out!). All you need to get started is a MetaMask wallet. You can use test tokens to buy prepaid cards, subscribe to service providers, register new service providers, and bill customers. Here’s the link to Tally: https://staging-tally.stack.cards/ You can find all instructions on how to obtain test tokens and start using Tally in this blog post:

Here’s an in-depth article to go with Chris’s strategy talk about the Cardstack product! Read about the different participants of the ecosystem, how they are connected with each other, and how Cardstack addresses their needs using the Card SDK, the CARD Protocol, and the Cardstack Hub.

Always great to rewatch: this short video about the future of content creation and distribution—done the Web 3.0 way. Cardstack enables makers, storytellers, developers, and designers to form decentralized networks and finally create on their own terms!

Are you an engineer? A developer? More like a power user? Whichever category you fall into and whatever skill set you have, it is more than enough. You don’t have to learn NodeJS or Ethereum to contribute to the Card Catalog—to create meaning, write content, and share it with the world. Everyone can play an important role in the Cardstack Ecosystem. In this blog post that accompanies his tech talk, Chris tells you how it works!

This weekend, our engineer Jen Weber is attending ETHBOSTON—the Ethereum hackathon hosted by ETHGlobal, where over 100 developers come together to work on dApps. If you're interested: https://eth.boston/

Congrats to Jen Weber and her team, who won the creativity award from Torus at the ETHBoston hackathon last weekend! Their project was all about privacy & identity. They built SkipID—a dApp to simplify sign-in processes at conferences. The app lets you log in with Torus OAuth and generates a QR code that can be scanned at sign-in, thus eliminating the need for ID checks. It shows a preview of your conference badge too. You can find more details and a quick demo here: https://devpost.com/software/skipid

Our engineer Jen Weber recaps her experience at the ETHBoston hackathon she attended last weekend. Jen talks about the different challenges faced by developers; she provides tips for hackathon sponsors to improve the developer experience; and finally, she explains how her takeaways from this event tie into Cardstack’s strategy and potential.

Get ready for EmberCamp! On Sept. 16, our lead developer Ed Faulkner and our engineer Jen Weber will give a talk at the second annual EmberCamp in Chicago. Learn more about the event and/or buy tickets: http://embercamp.com/

Congratulations Chris Tse & Hassan Abdel-Rahman on being granted a patent as co-inventors for rights transfers using blockchain transactions by the USPTO (United States Patent and Trademark Office)! This work, which was done as part of Monegraph in 2014, laid the foundation for a lot of digital collectible projects ever since.

A customer uses a prepaid card to pay a service provider, by staking some crypto value into the smart-contract-based token pool (where all crypto assets are pooled together). Customers who only have fiat money can buy prepaid cards from retailers, who do the staking on their behalf. Through usage accounting (on-chain and off-chain), we meter the usage and provided services across the network. Tally (acting as the accountant or bookkeeper) marks the prepaid cards, the value, and the spend history to market—so that people know how much they can deposit, how much their deposit is worth, and how much can be withdrawn.
