Bounty Description:

Decentralized version of coinmarketcap.com. All data stored only on Bluzelle. End product should be similar to CoinMarketCap.com.

Part 1.

A cron job or recurring process running on some server, that needs to pull order book data from CoinGecko.com's API (feel free to use some other service if you prefer). Use the free API, that allows access to read the currency pairs. Store this data directly to the edge on Bluzelle DB.

Whenever a new bunch of currency pair updates come in, update these all to Bluzelle immediately. We would like this to update to Bluzelle as frequently as possible, in terms of how frequently the order book API allows and is possible, with the goal to also demonstrate and prove out Bluzelle's ability to handle heavy batch updates in short timespans.

Part 2.

Web app (much like CoinMarketCap.com) pulls this data directly from Bluzelle using the Bluzelle JS libraries. The web app itself is simply static JS + HTML5 that can be hosted on S3 (or elsewhere).

May i suggest considering the CoinGecko Public Open API https://www.coingecko.com/en/api
No need to worry about keys and stuff. for instance https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd

Work has been started.

These users each claimed they can complete the work by 8 months, 3 weeks ago.
Please review their action plans below:

1) gbaquedano has started work.

I like how easy Bluzelle makes it to replace what used to be a complex infrastructure by just a javascript libray.
Project will have two parts, a service and a frontend:

  • Service will be a javascript (node.js) based application that works with at least one cryptocurrency API for pooling the market and updating the cache. If not enough updates are received (due to request limitations), additional data may be fetched from other sources.
  • Frontend will be developed as a SPA, probably using an existing javascript framework like Angular.

Good luck everyone.
2) brucewang11 has started work.

cycle call API to write blz database,and cycle read blz database to show on the website
3) deusexmachina892 has started work.

Tech stack that I would be using:
Express backend, React frontend, and Bluezelle SDK
First will work on the backend server and then on the frontend UI
4) ducbo97 has started work.

How to complete the task in the fastest and most effective way

6) aly0692 has started work.

Piye to jane iki jan ket mau gak mudeng blas
7) willxing has started work.

Plan:

  1. Find a cloud service to host the data fetching app
  2. Implement data fetching service running recurring to get data from coingecko api and write into Bluzelle db. Will choose node.js to develop
  3. Implement web app which will contain a table of the data get from Bluzelle db
    8) davideserafini has started work.
  • Create a serverless application as backend on AWS
  • Create a simple frontend with static JS + HTML5
  • Keep external library at a minimum
    9) bemijonathan has started work.

Im interested in rebuilding this web app to improve my knowledge of cryptocurrency market
10) yingyaox has started work.

  • Pull data from external API and store on Bluzelle
