Overview

Cardstack is an open-source framework and consensus protocol that makes blockchains usable and scalable for the mass market.

Project stage

Beta version

Detailed description

Cardstack is a leap forward for blockchain at every layer of the software stack - providing a toolset that unlocks the potential of the decentralized Internet for everyone.

App Framework
Cardstack Framework is a comprehensive SDK for building powerful, cohesive blockchain apps. At the core is Cardstack Hub, which orchestrates data and value transfer across multiple blockchains and the cloud.

Aggregation Protocol
Cardstack-powered dApps can tap into the Tally protocol, which gives dApps the power to perform complex computations to organize large networks of users — such as batching payments, counting votes, and rewarding good work.

Ecosystem Token
Developers can monetize their Cardstack- based apps via the smart contracts powered by the Cardstack Token (CARD), an Ethereum-based ERC20 token designed to fairly reward Cardstack- powered communities.

Cardstack’s approach to decentralizaton lets self-sovereign users act as their own hub, so that interactions with applications and services running on networks of different topologies flow through a software stack controlled by the users.

Problem

Centralized tech giants force us into silos, and capture the value we create. Early decentralized tech like Bitcoin demonstrates the promise of blockchain, but has only delivered gains to a handful of enthusiasts. Cardstack is a leap forward for blockchain at every layer of the software stack—providing a toolset that unlocks the potential of the decentralized Internet for everyone.

Solution

Developers can use the Cardstack Framework, a comprehensive SDK, to create powerful, card-based blockchain apps. Build anything using modular narrative and discovery containers. Easily construct custom workflows using our Cardstack Hub, which orchestrates data and value transfer across multiple blockchains and the cloud. Drop in ready-touse functionality like searchable indexes, realtime notifications, uniform user permissions, flexible containerized deployment, and much more. Everything is extensible, and is 100% open-sourced. Cardstack is a revolutionary experience layer that makes blockchain technology usable and scalable—creating a decentralized software ecosystem that can challenge today’s digital superpowers. 

This ecosystem is governed by smart contracts powered by the Cardstack Token (CARD), an Ethereum-based ERC20 token. CARD isn’t just any old cryptocurrency: it’s designed specifically to create a sustainable marketplace where open-source developers are rewarded fairly, while allowing users to curate and combine the perfect mix of software services to fit their needs. Just like other cryptocurrencies, CARD users can become miners to validate transactions and earn fees. But unlike Bitcoin—which forces miners to solve useless math problems —Cardstack analytic miners help calculate the reward function of who gets paid out what, while sifting out spam, making the system fair and resilient. Analytic miners’ results compete in a sortition scheme we call proof-of-analytics, so reward algorithms are never under a single party’s control.

Features

  • Mix and match multiple dApps and cloud apps; 
  • Create amazing new workflow and app combinations using Cardstack Hub; 
  • Use one token (CARD) that forms retainer agreements with all the services you need; 
  • Keep your data sovereign, or transmit it anywhere easily, with our card-based user experience; 
  • Get started quickly with fiat currency: no crypto expertise required. 

For Developers: 

  • Use our comprehensive SDK to build powerful, beautiful, extensible apps; 
  • Access a deep library of powerful drop-in functionality; 
  • Improve your app experience using Cardstack’s off-chain aggregation; 
  • Get paid fairly by our community-run payment and governance algorithm; Get reimbursed for your material costs;

For Analytic Miners: 

  • Do the useful work of powering community-run algorithms that create a fair distribution of wealth; 
  • Help protect the system against outliers, bad-faith actors, and spam; 
  • Earn fees in the form of Cardstack Tokens that can be held or circulated back into the ecosystem; 
  • Get compensated via a sortition scheme that prevents single parties controlling the reward function.

    • Token symbol ? Token symbol — a shorten token name. It is used during an ICO and after the coin listing at the cryptocurrency exchanges. : CARD
    • Fundrasing target ? Fundraising target — the maximum amount of funds to be raised during an ICO. When it is reached, the developers stop selling the tokens because they do not need to raise more money for the project development. : 35,000,000 USD
    • Token type ? Token type — a platform for a startup launch that influences the stability of blockchain operation, the speed of transactions and the fees. :Ethereum (ERC20)
    • Soft cap ? Soft cap — the minimum amount of funds to be raised for the project development. Sometimes when the soft cap has not been reached, the money is returned to the participants. :10,000,000 USD
    • Role of token ? Role of Token — type of token depending on the opportunities it offers to its owner. Utility tokens give their owners a right to use the project services, security tokens are aimed at bringing profit, and currency tokens are a money substitute. :Hybrid token

    • Whitelist ? Whitelist — a list of participants, who get an opportunity to buy tokens. To be whitelisted, you need to register on time because the number of participants and the registration period are usually limited. :Whitelist Closed
    • Additional emission ? Additional emission — an additional release of tokens. It can be done once after the crowd sale or on an ongoing basis. In the projects with a limited emission there is no additional emission. :No
    • Exchange listing ? Exchange listing — an assumed date when the token will be listed at a cryptocurrency exchange. The developers usually indicate it in a roadmap and a white paper. :NA
    • Accepting currencies ? Accepting currencies — cryptocurrencies and fiat currencies that can be used for buying the project tokens. :BTC, ETH, USD,
    • Can't participate ? Can't participate — the countries where it is prohibited to buy tokens. These can be countries where ICOs are prohibited altogether, or countries that have the requirements that a particular project does not meet. :Cuba, Iran, North Korea, USA,
    • Know Your Customer (KYC) ? Know Your Customer — a verification procedure for ICO participants, during which the developers can ask for personal data, a photo and a scanned copy of a passport of a potential investor. :No

  • Token and Funds Distribution

    Token distribution date

    60% of the generated tokens will be distributed in Year 1 through early contributor agreements, pre-allocation, crowd fundraiser, airdrops, Year 1 ecosystem initiatives, and advisors/partners allocations. Allocated tokens will be available for peer-to-peer usage at the conclusion of the crowd fundraiser, which will begin no more than 60 days from the conclusion of the pre-allocation period. 

    The airdrop awards will occur throughout the first year, with each airdrop event limited to 2% of the generated tokens. There will be a public announcement at least 30 days before each distribution event, allowing interested participants to prepare their prerequisites for the awards.
