Crowdvote – A Community Driven Decision Making Model To Compensate Blockchain Developers With CrowdstartCoins XSC

Crowdvote – A Community Driven Decision Making Model To Compensate Blockchain Developers With CrowdstartCoins XSC

CrowdstartCoin

Big news over at Crowdstart: with CROWDVOTE we will provide a community driven opinion forming and decision making model that follows on the present centralized distribution model of CrowdstartCoins XSC.

Starting with our IOTA hackathon in Gdansk, in November 2017, we have distributed CrowdstartCoins XSC to over 2,000 developers who have added valuable code to the blockchain ecosystem. As promised, we at Crowdstart do not think that we are the best people to decide who is eligible to receive CrowdstartCoins XSC, but rather it should be the responsibility of the entire blockchain community to form opinions and make decisions that define the distribution of XSC.

CROWDVOTE to be launched at DAHOAM Tech Conference
We announced our plan of developing a liquid democracy model to enable that kind of a decentralized decision making process last November. Today, we are very happy to announce that we will launch the first version of CROWDVOTE at DAHOAM Tech Conference, on July, 24.

With CROWDVOTE, members of the blockchain community will be able to propose and vote for blockchain projects supporting them to receive their deserved CrowdstartCoins XSC. In the first version, there still  will be some centralized elements; e.g. there will be a set of rules that define the proposal and voting mechanism. A framework of rules has to be implemented from the start – otherwise the model would create more confusion than joy about the new decision making opportunities. Our plan, however, is to go further and also decentralise these aspects. In future versions of CROWDVOTE, the community will be able to define the rules for proposing and voting for projects by themselves.

Want to participate and help CROWDVOTE to be developed?

If you are generally interested in decentralise decision making processes and liquid democracy, please feel invited to participate and support the development of CROWDVOTE. Send us an email to crowdvote (at) crowdstart (dot) capital.

Blockchain Meetup 12: The Convergence of AI & Blockchain

Blockchain Meetup 12: The Convergence of AI & Blockchain

The Convergence Thesis: We strongly believe that blockchain technology will prove as the key underlying technology stack for the technologies that emerge with numerous applications on top of it. This view has been influenced by Outlier Ventures’ Jamie Burke, who coined the term ‘convergence’.

Blockchain provides an infrastructure for emergent trends like; IoT, 3D Printing, Autonomous Robotics (drones) to scale securely. More specifically, there are a handful of emerging technologies that hold the most promise for this blockchain-enabled convergence:

– Artificial Intelligence (AI)
– The Internet of Things (IoT)
– Autonomous Robotics (Drones & Autonomous Vehicles)
– Virtual Reality (VR) & Augmented Reality (AR)
– 3D Printing

A Wallet + DAPP Browser Market Overview

A Wallet + DAPP Browser Market Overview

Here’s a quick overview of four of the newest crypto wallets with built-in DAPP browsers

If ethereum is to realize its promise as the “world computer” we’re going to need more advanced wallets.  Mobile has arguably overtaken desktop as the dominant paradigm for interacting on the web but most decentral applications aren’t mobile ready. DAPPs promise to be our connection to voting, governance and the backbone of the web’s future. There are lots of mobile wallets available now but in the coming world, just sending tokens and crypto back and forth won’t be enough.

Today we’re taking a quick look at four bleeding-edge wallets which combine a DAPP browser with a mobile crypto wallet. Since development in this area moves very very fast we’re not going to make any kind of a ranking.  Instead, we’ll list a few key features where each app shines.

Cipher wallet logo

Cipher Browser

The Cipher Browser has a solid DAPP browser which handles the login process for early DAPPs such as cryptokitties.co and leeroy.io as though one was using metamask. The Touch ID integration is good and approving transactions is pain-free. In addition, adding custom ERC20 tokens to the app is quick and straightforward if you are someone who knows their way around etherscan and who’s not afraid to find out how many digits a token contract allows.

Who’s it for? Old-school crypto nerds who want to keep it simple.

Toshi icon

Toshi Browser

The open source Toshi browser is not only a wallet and a DAPP browser but also an encrypted chat platform. It uses a chatbot for the initial user journey which in our experience is an either a “you love it or you hate it” kind of thing.  After that, one can access an app store like DAPP browser, a public chat client based on identities tied to ethereum addresses and a wallet supporting both fungible and non-fungible ethereum assets.

Toshi uses the Signal protocol by Whisper Systems for chat and the uPort identity protocol to store user profiles.  All in all, it’s pretty forward thinking stuff if a bit cluttered at times. There’s also one weakness for industrial applications. Developers and other geeks may want to work on more than one network (Testnet, POA etc.) If that’s your use case, this one isn’t for you.

Who’s it for? Social crypto nerds who love trying out new stuff.

status icon

Status Browser

Status takes the social / chat idea from Toshi to the next level.  In Status, one finds not only contacts in the chat interface but also DAPPs.  As in Toshi, setup occurs via a dialogue with a chatbot.  Again this isn’t for everyone, but it’s super for people who prefer onboarding by bot.

Status defines itself as a new kind of peer-to-peer encrypted messaging and payment system rather than a DAPP browser or a wallet.  Yes, it does offer those things too, but everything in the Status app is centered around chat.  The idea is that people do business and transact with other people, so their communication should enable that.

Right now, status is only available as an alpha release that you can test on the testnet using Testflight (iOS). There’s a very lively Discord community if you want to jump in and join the dialogue.

Who’s it for? Do you dream of native ethereum transactions while using whatsapp? Then this app is for you!

trust wallet icon

Trust Wallet

Like Cipher, Trust Wallet offers a more conventional experience.  There’s a browser tab, a transactions tab, a tokens tab, and settings.  Everything is pretty self-explanatory.  The Web3 integration in the DAPP browser is great, so log in and transaction approval are simple. Also, the developer is working with decentral exchanges such as Kyber Network to make sure the DAPP creators are building stuff that is actually usable on mobile.

Also, this open source app is the only one on our list that may be appropriate for use in industrial applications.  This is due to the fact that the Trust wallet allows the user to switch the network and that a proof-of-authority network connection is possible.

Who’s it for? Crypto industrialists, exchange integrators, open source forkers and friends of straightforward wallet tech.

Two Token Model TTM – A Cryptoeconomic Approach For (ICOing) High-yield, Stable Decentralized Networks

Two Token Model TTM – A Cryptoeconomic Approach For (ICOing) High-yield, Stable Decentralized Networks

On December 6, 2017, game company and distributor Valve announced that its gaming platform Steam is no longer accepting Bitcoin as a payment method. The company explained that Bitcoin transaction fees have gone up to nearly $20 per transaction last week, “compared to roughly $0.20 when we initially enabled Bitcoin.”

At the same time, CryptoKitties burned up 15% of Ethereum’s gas, causing a mid-level congestion and increasing in-game fees.

Since we have been working on some ICO projects over the last months, focusing on cryptoeconomics and token design, we felt the need for a model that would allow a high-yield return for investors on the one hand, whilst guaranteeing the stability and a proper functioning of the specific application(s) at the same time.

Two Token Model TTM Thesis
Decentralized networks need a token model that

  1. guarantees a stable cryptoeconomic mechanism to exchange assets, services, time and money between peers, and, at the same time,
  2. allows investors to reap large economic benefits, and, therefore
  3. allows an overall story of combining a cooperative/post-capitalist model with a pure capitalist play by technically separating both aspects through the representation of two dedicated tokens.

Proposed Solution

A) Two-Token Model

The network features 2 different types of tokens:
a) a core token (CT) that is tradable at crypto-exchanges,
b) an application token (AT) (per application)

CT
The only function of the CT is that of a currency. In all of the network’s potential applications, there is one overarching CT.

AT
The AT is designed depending on the respective application’s requirements. It is the only token that allows the usage of the respective application. It is not listed at any exchange. Potential listings of ATs probably could not be prevented technically, but by regulation: The network defines the listing of AT’s as not allowed and will exclude applications that behave otherwise. Organizers of applications that already have a token will be offered to exchange their tokens for AT. Additionally, they can be awarded CT depending on their applications’ asset values.

B) Token Issuance Mechanism

Initially, there will be two events that happen at the same time:

  • SAFT of CT to (accredited) investors
  • One-time distribution of (free) AT to interested potential network application users (comparable to a basic income)

The Token Story

A (revenue-driven, high-yield) SAFT will finance the development of the network and serve as the initial AT supply of the network. Within the first applications running, AT holders can earn additional AT, and, directly derived from that, additional CT. The intensity of use and supply of AT represents the intrinsic value of a CT.

This model of a clear, technical separation into  – and combination of – a speculative and an application part should serve the initially conflicting interests of both categories of the network‘s stakeholders: the potentially application-interested majority of AT holders and the potentially solely commercially driven and high-yield-driven investors who hold and trade the CT.

Every app token holder (ATH) will receive CT’s additionally to their AT’s, if the intensity of use of the application reaches a certain threshold. As long as the intensity of use is above this threshold, the ATH will receive additional CT’s, scaling with their intensity of use. When the intensity of use sinks below the threshold, there will be no CT’s awarded further on.

Definition of Intensity of Use IoU Criteria

As mentioned, ATH are being rewarded CT depending on their intensities of use of the application(s). There are several aspects of defining an “intensity of use (IoU)” in a good way. First, an ATH could use a specific application very frequently. This could add to her IoU. Then, the ATH could move huge assets within an application. Again, this could add to her IoU. Further on, an ATH could use an application in a way that leads to a higher IoU of another application. This would lead to trans-application elements of the IoU’s algorithm. Then, there are further aspects, s.a. hoarding/inflation, etc..

Model Attractiveness

The definition of the IoU algorithm is one key aspect of this token model. On the one hand, it seemingly is the most complex problem to solve for the network. On the other hand it offers the opportunity to create one single algorithm that is completely variable in design and can be tweaked throughout the lifespan of the network without any need for changing the structure.

Due to the fact that the AT is not tradable, and the IoU algorithm prevents the ATH from hoarding and other unintended use, it can be regarded as stable.

The CT, in turn, is a tradable token that entails no other rights than being exchangeable with other currencies. The prize of the CT will be defined by market forces alone. This pure market-driven nature of the CT, combined with the value(s) of ATs, makes the network’s model highly attractive for application-focused users, as well as for investors.

We have intensely discussed the TTM within our network, and we have not found severe weaknesses that could prove to become showstoppers. However, we invite you to prove otherwise! Please provide us with your feedback on TTM – thank you!
