Frontend php, java, back end NODEJS
laravel framework,
Please on no account should u use NOSQL , and the use on MongoDB framework
POINTS TO CONSIDER WHEN CREATING THE SITE
1. Blockchain Layer/ MULTIPLE COINS
Lets jump into the bitcoin/blockchain part. Important components here are:
* Generate bitcoin addresses for users,
* Receive payments,
* Send out bitcoins
* Confirm incoming transactions after n confirmations
2. The peer to peer marketplace part
Create offers/ads
Markets connect buyers and sellers and offers are the central objects that let them discover each other. Set your rules here. These decisions will affect everything and can dynamically change the marketplace culture and economy.
* Are payment methods hard-coded?
* Will you allow users to dynamically create new payment methods? Drop down or Stackoverflow tagging system approach?
* Set payment window time? I.e 90 minutes for buyer to complete payment or 3 days for a check?
* BTC price premium? I.e 10% over the average price across all exchanges?
* Which users can see which offers? I.e only logged in users with at least 10 completed trades, 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, activating, deactivating and so on.
The trading part
When users decide to accept an offer and begin a trade they are essentially in a live instant messaging session that has a process flow. With every point reached there are different rules and logic.
* Start trade
* Mark trade as paid
* Complete trade
* Auto-cancel trade
* Cancel trade by user
* Dispute trade
* Leave feedback
For all these mentioned 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 accidentally records or simply break database schema. Not to mention that the entire process must MAKE SENSE to a first time buyer and guide them through step by step. This process cost us quite a few hairs on our heads. Good luck!
Trade live chat
This is a lot deeper than it may seem and depends how fancy you want to get. Are you going to use primitive AJAX long polling or 3rd party plugins like Pusher, Firebase or your own solution with web sockets, XMPP and OpenFire or abstractions like Faye or Converse.js. Consider also that you need moderator messages in case of dispute and anything else you see there.
File Upload and video
Media is an integral part of the trade process. Sellers want ID, receipts pictures and sometimes even a live video feed. Building these is tough but securing them doubles the complexity. We suggest going with the leading third parties here to avoid keeping any such media on your servers. Security first!
Feedback system
This is another critical part to keep your platform fair, safe and scammer free. The rules here have an EXTREME impact on market dynamics as reputation is the beating heart of any free market. What decisions shall you make? Leave feedback for every trade or per trade partner? Our approach is to leave feedback to every trade and a reply can be left too. In case of dispute a loser can’t leave feedback. We listened to our traders and built the feedback system for them. Win Win Win!
Reporting capabilities for any historical data/actions
That is what your users would require from you. Some of the power sellers will be doing alot of trades and need to report their profits, trades to their government and tax authorities. Make data generation and exporting very convinient for them. For historical data users want to see their completed trades, activity ledger, transactions ledger, generated bitcoin addresses and any other historical data there might be. This is a huge project in and of itself. A whole startup could be built helping pro traders track profits.
Backend admin for website health.
Because you are probably in custody of users funds you surely want to know at any moment how much bitcoin is kept in your system and what is total bitcoin balance, users balances in database, active trades, history and anything you can think of and you want to see it in real time.
Cold Storage
Lets not forget cold storage! Set watch addresses for your cold storage and think of procedures that you have to follow to refill hot wallet/move funds to cold storage. This is another deep topic and worthy of a long guide.
Advertisement page
This is one critical part of the system , as u have to create an advert for user to be Able to post trade , in this option users will have the ability to create a trade for multiple coin, how will you make that work ? How will u be able to control user from creating more than 3 advert ? What limit of advert do you want users to have ? And when they don’t have Btc , or any other coin will their advert post ? Can they post it ? What about converting each coin to have an updated price(I would like to earn ??? Current bitcoin marketprice is 7 832,73 USD.I'm selling for 8 224,37 USD per bitcoin.I will get 105% of iTunes card value.I will earn 391,64 USD for every bitcoin I sell)? will you use bitstramp? What about updating over 300 payment method for users to chose from ? Who can create trade ? Will trade show if they have no Btc? Payment window? How long can user post trade for before it cancel ,? Trade limit( how much are users willing to buy )? Who can post trade ? must all account be photo verified before they can post ? Okay I am selling alone must I verify sms and photo before I can ?
