Bitcoin web wallet.
1. Important parts are: generate bitcoin addresses for users, send out payments, receive payments and confirm transaction after n confirmations. All at the same time properly handle users balances.
2. Create offers/ads. When you have basic flow of users bitcoin wallets in hand, it's time to move into marketplace part.
First part is the offer creation. What are the rules here like hard-coded payment methods (we went step further and allow users to dynamically create new payment methods), payment window time,
BTC price margin, offer visiblity to users? etc etc... Additionally have all the CRUD (create,read,update,delete) operations for the offer and all the business logic like updating price every 10 minutes, activation, deactivation etc...
[url removed, login to view] comes the trading part - start trade, mark trade as paid, complete trade, auto-cancel trade, cancel trade by user, dispute trade, leave feedback.
For all these trade actions the business logic has to be extremely well thought through and code written well with all edge cases taken into account.
Otherwise you can end up with adding balance twice, deleting accidently records or simply break database schema.
[url removed, login to view] live chat - Not a small part, considering that you need file upload here, moderator messages in case of dispute and anything else you see there.
[url removed, login to view] system is another part. Would you make it different? How complex would that be then? We have different feedback approach - feedback can be left for every completed trade and also a reply can be left.
In case dispute a loser can't leave feedback.
[url removed, login to view] capabilities for any historical data/actions - users completed trades, activity ledger, transactions ledger, generated bitcoin addresses and any other historical data you need to output.
[url removed, login to view] admin for website health - bitcoin balance in bitcoin cores, users balances, active trades, history, anything you can think of you want to see in real time.
