Based upon Ethereum for the logic and IPFS for the content, Agora is the first market thought in the interest of all parties. Register on it using your current Ethereum Wallet and then you can buy or sell over the marketplace*. An automatic system is holding the funds during the transaction. That way, if something goes wrong you can always get your money back.

Background and motivation

In this world of online marketplaces we are living in, the need for a fair online marketplace has never been this high. There is no power balance between the consumer and the merchant. Scams are rampant, getting money back is always hard, and as a seller as soon you make a transaction with a consumer, you cannot be sure he will not try to make a false claim. We want to be part of a more sustainable economy. This is why after a long period of brainstorming, documenting and researching we are proud to present you Agora. Agora is what we believe to be a step toward a fairer world.

Some companies tried to resolve this issue by creating trust labels. But all only few companies are indeed trustworthy. What if these companies fail in their duty to check data ? The issue of trust is just moved to another supposedly "more trustworthy" actor, but is still not resolved. So, the real questions behind a marketplace are : How can I trust an unknown seller ? How can I make a transaction with them ? How can the seller trust me if I say I didn't receive the package ? These questions are legitimate, and we tried our best to provide an answer.

Why Ethereum and IPFS ?

Blockchains have changed the way we can trust each other. First with Bitcoin, now with Ethereum, we can trust the ledger we are sharing together instead of trusting each other directly. Today, Ethereum is one of the most popular blockchain that supports smart-contracts. It aims to replace server computing as we know it, by creating a “world computer”.

IPFS is the technology for asset storing and file sharing on the internet in a purely decentralized way. It aims to replace HTTP by creating a better solution to share files across the internet.

What is a smart-contract ?
A smart-contract is code deployed on the blockchain. It is used to define and enforce the relationship between actors on the blockchain. And since the blockchain is immutable the code of the smart contract cannot be altered. On a blockchain, a smart-contract is like any other actor. It has an address, a balance and can do actions (sending money etc…) but it also has a brain: it can perform actions and store information

What is IPFS ?
IPFS stands for InterPlanetary File System. It is a protocol designed to create a peer-to-peer, addressable, distributed file-system. This is the technology that will be used to store assets such as stores’ pictures, products’ pictures, products’ description, in a distributed way. An asset stored on this filesystem has an unique address that can be easily stored in a smart contract.

How will we use these technologies ?
Our engineering team has leveraged the possibilities of Ethereum to build smart-contracts over the Ethereum blockchain that defines the relation between "sellers", "buyers" and “shareholders”. Furthermore, we will use IPFS to store assets to provide a user-friendly store without centralizing all the data at one point.

Relationship definition

To create a fair market, we need to enforce a set of rules between sellers, buyers and shareholders. Here is the exhaustive list of these rules.

• A seller cannot receive the money of an order before the buyer confirms he received the transaction, or after a defined period after which the buyer cannot make a claim anymore.
• An order cannot be processed if the buyer doesn't provide the required amount of money.
• When there is a dispute between a buyer and a seller that can be solved amicably, the shareholders may decide on the action to be taken to resolve the conflict. To do so, the shareholders can ask for proof and choose between three outcomes :
• Seller is in their right, buyer is not. All the money is given to the seller.
• Buyer is in their right, seller is not. All the money is given to the buyer.
• Shareholders cannot decide by majority, they can decide to split the money between the two parties.
• When a transaction is made over the market, a fee equal to 2% of the transaction amount is held by the market.
• At the end of each month, token shareholders can take their part of the 2% collected during the period based on the amount of tokens they hold at the closing date of the month.


After a purchase is made over the marketplace, the buyer can leave comments for the seller and another about the product itself. They can also rate both. After enough feedback, we can rate a seller.

Market regulation

The content of the marketplace is regulated. We don’t want to see illegal goods or services spawning across the market. When a seller wants to register, it’s status is set to “under registration”. A seller which is "under registration” is not yet shown to buyers. A certain amount of shareholders must approve the seller before the status goes from “under registration” to activated. Furthermore, a seller can be reported and removed.

3 smart-contracts

All smart contracts are concerned with the following : market logic, tokens logic and claims logic.
Market logic
Holds the logic that permits orders to be managed. It also manages the users, the store list, and the products on each store.
Tokens logic
Provides the logic that permit tokens to be emitted during the ICO period, then to be traded. It also maintains the logic of accounting and closing date.
Claims logic
Allows token holders to claim their part of the 2% during the latest gathering period

User experience across the marketplace
We have summarised the interaction between users, actors and contracts. Interacting with a smart-contract through raw transactions is not acceptable for most users. That’s why we believe we must make this market as user-friendly as possible.

Our vision is the following : the user goes to, provides its wallet file or plugs its hardware wallet (like a Ledger Nano S) and can start using the app. No matter if he is a buyer, a seller or a shareholder, it must be simple and easy to use. So the first thing to remove is the need to install a full Ethereum node or a full IPFS node.

To permit such a system to exist, we need to use public nodes and use web applications that can be executed only on client-side. MyEtherWallet is doing this. They use the wallet locally to transmit the signed transaction to a public node that relays it over the network. For IPFS, we can use a public node too.

This way a user can use the marketplace without needing to run a node, and can use it without uploading its wallet somewhere. Everything is happening locally and is broadcasted to the network when needed.

Furthermore, work is in progress on both the Ethereum and IPFS projects to enable bootstrapping a node directly from the browser. When this technology becomes available, we will be able to use it and connect directly from the browser without the need of a third-party public node. Another aspect that we want to simplify is billing which can get complicated. To make it easier, the market will generate bills automatically after a transaction is made. Since the market stores all the transactions on the blockchain, we can directly use the blockchain data as the support to create a PDF document on the client side.

We have created some basic wireframes of the views of the market so you can imagine more clearly what it will look like.

Unified experience

All users, whatever their role, must be able to use the marketplace without typing a single command line. Our goal is to make a fully functional marketplace using only Ethereum and IPFS, without installing a node locally and without interacting with the contract in command-line interfaces.

Unified experience

The profitable place
We are open by nature, and being open by nature means being transparent in every aspect of Agora. Our business model is as open as our code is : completely. Agora will be profitable for shareholders. The 2% taken from every transaction made over the market is shared among shareholder. Around every 30 days (157553 Ethereum blocks) every shareholder can claim its part of the fees gathered during the period. The part is calculated using the number of tokens owned by the user at the balance sheet date point in time.

The first step of the project is the Initial Coin Offering. The ICO is used to achieve two purposes :
• Raise funds to make the project a reality.
• Distribute all the tokens among the community.
We offer an unlimited supply of token, but the token creation is limited over time : around 2 month (315106 blocks). Here is the exhaustive list of rules enforced by the smart-contract :
• The contract is deployed by an address called “contract owner" which represents the development team.
• The token is expressed with 18 decimals.
• For 1 token created for a shareholder, 1/6 more token are created and given to the contract owner.
• Tokens owned by the contract owner are indefinitely frozen (not transferable).
• The ICO opens at block 4116800.
• The ICO ends at block 4431906.
• For a payment of 1 Ether you get 500 Agora Tokens during the ICO.
• A premium period exists between the block 4116800 and the block 4195576 (~2 weeks) where the price is 1 Ether = 550 Agora token (10% offer).
• The minimum Ether amount required to achieve the ICO is 500.
• If the amount of Ether raised is higher or equal than the minimum amount after the ICO end block is reached, the ICO is considered a success.
• If the amount of Ether raised is less than the minimum amount after the ICO end block is reached, the ICO is considered a failure.
• If the ICO is a success, the development team can withdraw the amount raised and start the development of Agora.
• If the ICO is a failure, every shareholder can destroy its token and get Ethers back. The development team cannot withdraw.

The token
The token (noted AGO) is a tradable token that represents a part of the marketplace. It is an ERC20 compliant token, so it is tradable easily over the Ethereum network. You can find details directly on More technical details are also available on our GitHub :


By nature, a smart-contract cannot be altered. Hence, we need to proceed very carefully with the smart contract development and deployment. And it is with a high-quality code requirement that we have designed the Roadmap. We can’t and won't rush. We want to provide the best experience available. We want to minimise the risk taken by the shareholders by investing into our solution. This takes time.

ICO Phase
(August 2017 ~ September 2017) This phase is described in the “Profitable market” section. After the ICO we will do some hiring, we will create the company itself. Smart-contract and web application development
(September 2017 ~ January 2018)
We want to take care of the software we are developing. Ss already stated, smart-contract development is a hard task since once a smart-contract is deployed it cannot be modified. We need to be really careful and do a lot of testing. Mobile applications development

(February 2018 ~ August 2018)
We want our marketplace to be available from a mobile-phone as well. And to achieve that, we will create mobile applications. Decentralized search engine

(October 2018 ~ March 2019)
A search engine across the market is hard to achieve since reading over the blockchain can be hard, and indexing field is almost impossible. We want to create a hybrid solution created across IPFS and Ethereum to achieve some of the searching task.

Postal services integration
(March 2019 ~ ?) Disputes will happen often, and we need a way to track deliveries. The blockchain is made for this use case, and if we work closely with the delivery services, we can offer an efficient tracking system for our sellers and our buyers.

Technical challenges

To create the market in its first version, there are not many challenges to overcome. But when it comes to the next part of the timeline we will have to overcome some big ones.

Creating autonomous mobile applications
If we want to create completely autonomous mobile application (that would not require to call an intermediate node) we need to find a way to pass over the NAT that is commonly used by providers. Before being able to that, mobile application will reach the decentralized services through public nodes.

Tracking parcels and deliveries from real-life providers
To make disputes management easier, we want to integrate parcels transporters within the blockchain itself. We need to dig this path deeper since it would be a really nice-to-have feature to secure the decisions taken by the shareholders or to resolve disputes without asking them to intervene.

Using nodes directly from the browser
Ethereum and IPFS are currently working on pure JS implementation. They have attained interesting first steps recently, and it will probably be the best way for us to cut the link with public nodes.

Building a client-side search engine
To search among the products of the market we need to build a new kind of search engine : a client one that generates its indexes over a decentralized file-system like IPFS with some data referenced inside a smart contract to ensure the validity of indexes. We want to use this search engine to browse the content, but we want to do even more with it : make recommendation to the user using only client-side information and the search engine. We could provide the first recommendation system that respects your privacy.
