Bazaar

THIS IS WORK IN PROGRESS recommended for developers only

setup ipfs uploads

In order to make our helper scripts work on our testnet, we need to upload metadata and assets to a public IPFS gateway. In this example we use infura.

export IPFS_ADD_URL=https://ipfs.infura.io:5001/api/v0/add
export IPFS_API_KEY=<KEY>:<SECRET>

create a pure proxy business account

In the future, we will recommend that businesses create pure proxy accounts for their business accounts. This way, control over the account can be distributed, revoked and multisiged

create a business entry for Bazaar

save the following as my_business.json

{
  "name": "Kueche Edison",
  "description": "bei uns gibt es köstlichen Kaffe",
  "category": "food",
  "address": "Technoparkstrasse 1, 8005 Zürich",
  "telephone": null,
  "email": null,
  "longitude": "8.515962660312653",
  "latitude": "47.390349148891545",
  "openingHours": "Mon-Fri 8h-18h",
  "logo": "QmUH7W2eAWTfHRYYV1YitZaz54sTjEwv6udjZjh7Tg47Xv",
  "photos": ""
}

The owner of this business can no register the business entry with the follwoing comman

./bazaar.py -u wss://gesell.encointer.org -p 443 --cid u0qj94fxxJ6 --bizaccount //Alice register-business ./my_busyness.json

This helper script will upload your json to IPFS and register its ipfs url on testnet gesell

verify on-chain registry with

./bazaar.py -u wss://gesell.encointer.org -p 443 --cid u0qj94fxxJ6 list-businesses

register an offering

An offering is a product with a price, so let's define the product:

save the following as my_product.json

{
	"name": "Kaffee",
	"description": "Köstlicher Kaffe",
	"category": "food",
	"image": "QmZzkgNe6B6M9Y3UeGgugwEB56v5qBm35bcPTPnZFNtY7d",
	"itemCondition": null
}

Let's register this offering with product and price

./bazaar.py --client "../target/release/encointer-client-notee -u wss://gesell.encointer.org" --cid sqm1v79dF6b --bizaccount //Alice register-offering my_product.json --price 42

This helper script will upload your json to IPFS and register its ipfs url on testnet gesell

verify

/bazaar.py -u wss://gesell.encointer.org -p 443 --cid u0qj94fxxJ6 list-offerings

While IPFS isn't very reliable in terms of discovery and availability, it represents the only content distribution method currently available which has a potential of working in decentralized setups. It is also content-addressed which guarantees that the correct content is delivered in untampered state.
