StockBlock is the best tokensale ICO for November 2017.


Marketplace for media artist

Your Artwork Copyrights and attribution on Blockchain (free forever)

Securely sell & trace your digital artwork with attribution

Empowering Photographers and Media artist
using Blockchain technology

Project Brief

With current stock media websites its impossible to track who uses your art work. With Blockchain technology, content creators will be able to track their artwork worldwide with greater transparency. It will also offer a much cheaper and more efficient infrastructural alternative to the current delivery model including instant payment to content creators worldwide.

Still image market size and growth


Compound annual growth rate

4.46 Billion

Stock Images Market by 2021

The Problem

If there’s one fear that’s shared by all creatives, it’s the fear of copyright infringement. It’s not enough to just credit the creator. You need explicit permission from said creator to use their work in the manner that you want to use it. Unfortunately, many people have trouble getting attributed and compensated for their stolen artwork.

Proposed Solution

Copyright & Licensing Security

Photos & Media with their copyrights protected and creators licensing attribution confirmed on open ledger are decentralized and tamper proof

Monitor your sold artwork

Keep track of sales on open ledger. Locate who uses your images and where. It can also search for modified images all over the world-wide-web.

Marketplace with no chargebacks

With blockchain, the risk of fraud is non-existent after the transaction is confirmed. There is no way for the fraudster to “charge back” the payments.

    The project Idea

    Group of entrepreneur friends discussed this project and copyright issues over local meetup.

  • Aug 10, 2016

    Planning stage

    Thought process on how to develop the platform and manage copyrights. We also had initial discussion on benefits of using blockchain.

  • Nov 10, 2016

    Prototyping & workflow

    Started prototyping with 2 full stack developers. Workflows, database and other development standards were setup on a private cloud.

  • Finalized  Ethereum Blockchain for the project Jan 18, 2017

    Finalized Ethereum Blockchain for the project

    In Ethereum the block time is set to 14 to 15 seconds compared to Bitcoins 10 minutes. This allows for faster transaction times. Ability to create tokens for the platform economy, ethereum blockchain made sense.

  • Mar 16, 2017

    Development in progress

    Marketplace platform development begins. Initiated cloud storage setup to handle large amount of images.

  • Jul 25, 2017

    Develop contracts and testing

    Working on contracts for copyright information that will be stored on blockchain. The contract stores copyright information along with image hash value of the images. Further contracts will also be used to create unique or extended editions of the artwork to be sold in the marketplace.

Project FAQ

Copyright law hasn’t changed much as technology has. The ability to secure copyright information on the blockchain is ideal. Once the information is registered, it cannot be altered. Therefore, a creator always receives credit without any possibility of dispute and provides you with a “proof of publishing”. Artists can track the activity of their work along with transparent sales and prevent copyright infringement. 

With the development of this project along with the marketplace, StockBlock is here to put the power back in the hands of the artists. 

Technavio, a leading global market research company headquartered in London, has released its annual report on the Global Still Image Market, looking ahead five years to 2021. They say: “Technavio analysts forecast the global still images market to grow to USD 4.46 billion by 2021, at a CAGR of close to 8% over the forecast period."

Proof of existence & ownership:

StockBlock uses the blockchain for artists to timestamp and create a permanent record of their work. This protects the content creator against third party claims over earlier authorship.

Help artist prevent copyright infringement:

The artwork will be monitored for anyone violating their copyright. None of existing stock photography website provides such service. 

Marketplace for digital content:

Anyone from anywhere can buy and sell artwork securely. With proof of existence and all copyright information in place, you are sure to buy verified artwork. 

Receive instant payments:

In most cases, blockchain transactions rarely go above 1 percent. That’s because you’ve cut out the middlemen, aka banks and payment processors, who are trying to make a profit as well by charging you to process a payment.  Despite the fact the blockchain is used to create a digital currency, it actually works more like cash than a credit card since once the transaction is approved by both parties it can’t be contested. Furthermore, you have to authorize and verify the transaction. This will reduce any disputes between you and your customers, which in turn will eliminate chargebacks. Using smart contracts and ethereum ERC20 Tokens(XMC tokens) the payments are instant and creative artist get paid for the same immediately.

The first obvious usage is to secure copyright information. Since the information created it cannot be altered, a photo can forever be associated to its creator without any possibility of dispute. 

StockBlock helps in tracking the appearance of an image online. It can locate web pages that make use of an image you have created. Discover modified or edited versions of an image. Help with image attribution.

A fair share of the transactions will be used to keep us operational. 

Perceptual hash functions will be used in finding cases of online copyright infringement because of the ability to have a correlation between hashes so similar data can be found. If a media artist user uploads an image that has a copyright, the hashes will be almost exactly the same and could be flagged as plagiarism. 

Perceptual hashing is the use of an algorithm that produces a snippet or fingerprint of various forms of multimedia. Perceptual hash functions are analogous if features are similar, whereas cryptographic hashing relies on the avalanche effect of a small change in input value creating a drastic change in output value. 

Copyright information along with the image hash will be used to create the smart contracts. 

“XMC Tokens,” will provide a smart payment solution for artwork sold in marketplace. The editors and moderators will receive tokens as payments for approving and moderating the artwork. Sellers receive XMC tokens which they can through the exchange service for any other number of cryptocurrencies or US Dollars, Bitcoin and Ether.

Once the platform is in beta stage, new offices will be setup in Europe (TBD). We are a small team for now and need community support to grow and make this project a huge success. We look forward to expand as and when necessary. If you are interested in the project, let us know how you can help.Email us
