Audio Player

Users can upload audio, i.e. songs, DJ Mixes, podcasts, audiobooks etc. which can be shared or distributed internally or externally to other platforms and potential users.

Curate Content

Users have the option to up or downvote content, thus curating good and bad content. Users earn rewards for making sure the content provided by imusify is top quality.

Create Channels

Users can create their own channels, similar to Slack, which are their own real-time and personified channels and playlists based on tags and topics. Users can invite other users internally or externally via email so only invited members have access to the channel.

$IMU Token

As soon as users sign up to imusify they are rewarded with an initial amount of $IMU. By curating content, either up or downvoting or commenting, users earn $IMU according to an algorithm implemented into the smart contract “incentify”. These tokens can be used to purchase or to stream music.

Smart Contract “incentify”

New users start off with an initial reputation level. This level determines the rewards the user gets for delivering or curating content. Depending on consistency and quality of contribution the users reputation level increases giving the user a right to higher rewards which are automatically paid out to the users wallet. Over time content creators and curators will have a stable source of income which can be converted into cash. imusify has no control over this as it is hard-coded into the immutable smart contract.

$IMU holders can vote and propose new features and changes on the platform

Users can purchase audio for personal and commercial purposes.

Service providers will pay a percentage of their revenue to support content creators and the imusify platform.

Authors earn $IMU tokens from selling recordings, audiobooks, podcasts and any other audio related content.

Authors earn $IMU tokens from receiving high-ranking reviews..

Developer Q&A

Can you outline the basic functionality of imusify?

As a platform, is a music sharing and discovery platform. In contrast with currently existing platforms, content on imusify is organized in Slack-like channels that can be easily and instantly created by the users.

imusify solves the main problem with Soundcloud and competing platforms, which is that artists currently must pay the platform for the right to use it. ímusify will take the opposite approach. Uploading, sharing and upvoting (curating) content is rewarded with imusify’s native currency $IMU, running as a smart contract on the NEO blockchain. Furthermore, over time imusify will become a place where users can buy and sell content using $IMU.

The basic workflow is as follows. When users enter, they can currently register, sign up and sign in via email. Soon also via Facebook and Soundcloud. All new users receive an initial reward in $IMU. Users will be able to import all their existing content from Soundcloud to facilitate an easy transition to a next level platform. Once registered, the user can fill out profile relevant information and upload a profile picture. All users will automatically see all content in the public channel #general where they can curate content by up and downvoting or also soon via commenting. Users can upload their own content, such as recordings, given they have all necessary rights to upload to the platform. Users can drag and drop music into the browser thus uploading it to the platform. During the upload, user is asked multiple questions in order to determine relevant Metadata. For every upvote, both the upvoter and uploader receive rewards in $IMU. For every downvote, the uploader loses $IMU. Content can be shared to other users, channels and external platforms. It can be curated by up or downvoting to ensure quality.

Our MVP is the first version of a free voting system to curate the best content. It is very limited in functionality at this point as we developed this in a very short time specifically for the CoZ competition. The magic is hidden in the background, the Smart Contract: Events on the Web user interface (see below) are signaled to the Python middleware designed for this project, which then triggers a return. And indeed, the awarded amount is not determined by imusify but by the contract and the users level alone. Beyond the NEP5 compliant method calls (which always enables users to freely exchange IMU tokens) the main chain of new methods of the imusify contract logic are as follows:

BigInteger LevelUp(byte[] account)
BigInteger RewardFunction(BigInteger level)
BigInteger Reward(byte[] account)
This is accompanied by the query
BigInteger LevelOf(byte[] account)

Before the final release, anybody can test the reward trigger and the reward scheme is designed so that the curious developer can test the functionality and quickly witness the effect of a level raise. At a later point, the scheme will be scaled for long term incentification of users.

You can find an in depth explanation video of the imusify incentify smart contract here and further information on our Github repo.

Who will use imusify and how will they benefit?

Put short: People who make music and people who love music. Any user can use Any user can benefit from imusify. Also, any user can get rewarded for contributions to the platform.

Users benefit in four main ways:

1. From having a new social music sharing and discovery platform, which takes the best features from phase-out models, improves them and combines them into a Smart music platform 2.0.

2. Thanks to the integrated imusify token artists can immediately monetize their content through the smart contract “incentify” and spend their $IMU to further boost their reach and distribute to fans, friends and family for more exposure.

3. imusify harnesses the security and immutability features of blockchain to improve copyright protection for content owners and to securely transact and keep track of content licenses.This gives artists control over their content and disrupts the big record companies ironclad control over artist’s revenue streams.

4. imusify provides a Network-Market effect for all aspiring entrepreneurs and industry professionals to connect, communicate, share and do business.

Further users include:

Content Creators:
Music Producers, Beatmakers, DJs, Turntablists, Curators, Singers, Rappers, Vocalists, Speakers, Beatboxers, Composers, Songwriters, Instrumentalists and Bands

A&Rs, Labels, Publishers, Managers, Bookers, Distributors, Recording Studios, Film Producers, Advertising Agencies, Music Supervisors, Film Cutters, Lawyers, Event Managers and Game Developers

Music nerds, “mixtape” makers, Indie music lovers, Music discovery gurus, Playlist curators

Use case example:
Online music platforms have been an integral part of any DJ/producer’s rise to fame. There have previously been problems with rightful owners of music getting their content taken down by their own record labels, which will be solved with imusify’s blockchain powered rights management system.

Another benefit is for DJ mixes. The rights situation for mixes is fairly complicated, where the rights to play a song in front of a live audience, does not necessarily imply the right to share it online. With music detection software a DJ can instantly pay the appropriate licenses for the tracks in the mix. Moreover, with the user curated channels and instant buying options, finding music while preparing sets has never been easier. Currently, many DJs discover music on Soundcloud, Spotify and other channels, and then have to find a way to buy this music in ultrahigh quality digital formats for use on large soundsystems. With imusify this could all be done on one platform.

What are your plans for ongoing development?

We are currently moving full throttle towards an ITO in order to raise funds for our development roadmap. Our first main focus is on the smart contract “incentify”. Besides “incentify” and standard social networking features such as following, search, browse, playlists and exploring we plan to make imusify a platform where users can make a decent source of income. We plan to achieve this by developing the following additional features features:

Webapp, Desktop and Mobile apps
For better collaboration and music discovery experience

Artificial Intelligence / Machine Learning
By implementing AI we will be able to understand user preferences better which enables us to curate and deliver a very unique user experience. AI will also help us determine rewards and loyalty points when integrated into our smart contract “incentify”.

Tools for copyright management
By utilizing NEO´s “Digital Assets”, which are programmable assets, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries. On the imusify platform users will be able to register their assets, such as music recordings or midi files, thus obtaining immutable proof of copyright. Proving the connection between digital and physical assets is possible through ”Smart ID”. Assets, in this case music, registered through a validated digital identity are protected by law.

Smart ID

Users will have the option to verify their identification. This will happen via NEO Smart ID which enables trustful verification:

- Facial features
- Fingerprints
- Voice
- Other multi-factor methods

Copyright holders will be able to sell their digital goods, such as music, as single or album. We have plans for enabling copyright holders to sell 1-click commercial use and sync-licenses for audio-visuals such as movies, corporate image videos or online videos like youtube etc. We will provide the opportunity for the following licensing cases:

- Film / TV Shows
- Music production
- Documentary / Indie / Student Film
- Corporate / Commercial Film
- Internet Video
- Websites
- Audiobooks
- Advertising
- Music on hold
- Games & Software
- Live Events
- Podcasts
- Non Profit

Collecting Income from the marketplace will no longer be the responsibility of copyright collecting societies (PRO) such as BMI, ASCAP or GEMA. As of now, the amount of royalties collected and paid out is only a fraction of what the artists actually earn. A good amount of money, again, remains with an intermediary, the PROs. With imusify the income will be transferred directly to the users wallets. No more collecting from collecting societies or searching and waiting years on royalties!

Distributed Storage

Utilizing Distributed Hash Table technology imusify will provide distributed storage for audio hosting at a fraction of normal hosting costs. Thanks to NeoFS, data is indexed through file content (Hash) rather than file path (URI). Large files are divided into fixed-size data blocks that are distributed and stored in many different nodes. This enables super fast p2p transactions while increasing security.

dApps launching tools
Developers creating music related dApps will be able to launch their products on the imusify platform. We plan to educate and support upcoming content creators, artists and entrepreneurs which plan to disrupt the music industry by providing both virtual and real world workshops. Long term vision is to form incubator and accelerator programs for all imusify members.

Multiple payment methods
imusify will generally accept fiat, bank-transfer and most cryptos as payment method for all of its services.

ITO / Crowdfunding for artists and bands
imusify will develop tools to launch crowdfunding events. We will accept $IMU, cash, bank-transfer and all cryptos worth mentioning.

Tools for collaboration
Users will be able to upload recordings, stems and stem packages with which users will be able to jam in realtime on a global basis while producing the next track.

Our experience was great. We ran into technical challenges but had immediate support from CoZ. The NEO Debugger also really came in handy. Our experience with NEO and CoZ has been flawless and we look forward to future cooperation.

“iMusify got top marks from me for being such a well executed dApp on all levels of the tech stack, from the Smart Contract to the user interface. It was also one of the first dApps to use neo-python as a blockchain middleware for communication between UI and a Smart Contract. I look forward to seeing the project continue to grow!”
