DevOps | Hyperledger Fabric

I have 5+ years of experience in Blockchain Technology. During my career as a Blockchain and Machine Learning developer I have worked on Hyperledger Fabric, and deployed smart-contract on Ethereum Blockchain Network. I am experienced with AWS Lambda Serverless Backend Development. Serverless architectures offer greater scalability, more flexibility, and quicker time to release, all at a reduced cost. AWS Cloud Development Kit lets developers define cloud resources for serverless applications. The resources can then be deployed on AWS Lambda using programming languages like NodeJs-TypeScript, etc.

We will deliver you Hyperledger Fabric 2.x blockchain network along with Monitoring Tools like Prometheus and Grafana Dashboard to monitor on the blockchain network performance. We will also deliver you a total of 5 Client API's Endpoint that will save and retrieve data from the Hyperledger Fabric blockchain Ledger. The Client API's will be hosted using Nginx Web Server. Our Hyperledger Fabric Chaincode/Smart Contract will be writer either using Javascript or GoLang, as per your preference. The entire infrastructure could be bought Up and Down by just a single command. We would need, a name for the project, a code commit repository, and a VM to host or deploy all this service.

Hyperledger Fabric 2.X with Monitoring Tools

In the Hyperledger Fabric network which is runninc on EC2 VM need to created an Ethereum Wallet so that data could be write/read/update/list smart contract.

PHP should be able to call for API should be able to send HASH and parameters to that application.

I have created a completely new cryptocurrency called PAPAN TOKEN on top of Ethereum Blockchain using Solidity Programming Language with the below features.
• The smart-contract is deployed in Rinkeby Ethereum Test Network.
• Token is called PAPAN TOKEN and with known symbol as PAP.
• The smart-contract has initial supply of 1000000 Tokens.
• Users can transfer the tokens to another people’s account.
• Debt or negative balance is not allowed.
• Anyone can buy the PAPAN TOKEN using fake-ethers.
• Buy price is set by Admin at any time of contract creation.

GitHub Repo: https://papandas.github.io/DAap-Token-Sale-Contract/

ICO – ERC20 Token

Project Details:
• To create the digital identity of three types of Nodes (Producer, Distributor, and Consumer)
• Create digital asset of produce/crop for the producer. Only producer is allowed to create a new digital asset in the network.
• Create a smart contract to allow:
a- Distributor to create order request for Producer
b- Producer can either Accept Or Reject any Order Request from Distributor
c- If Producer accepts the Order Request, the Order is sent back to Distributor for Payment.
d- Distributor Receives the Produce, and payment in Ether is released form Distributor and Credited into Producer Account.
e- Consumer can then come and visit Distributors and Purchase any order. Consumers can pay in Ether to Distributor.
f- Stock on the Producer should be updated to all the participants in the system.
• Deploy the smart contract into Rinkeby Test Network.
• Help the team to develop the front-end in NodeJS.
