I’ve been working on this project since July, and the smart contract is fully operational and deployed in EOS mainnet and Jungle2 testnet. The only problem, I could not find the time to implement a decent front end for it:

The idea is very simple: a contract owner makes a one-time payment to create a life-long entry in the catalog, and then the owner can edit its fields as they like. It’s also possible to withdraw the entry and get back 90% of the payment.

The contract maintains a revision number in its props table, so the front end can check it before retrieving all the tables from the EOS network.

I plan to add a JSON API and eventually a front end for the catalog.

First 10 entries receive a discount, so you better hurry up.
