Request Chain

Request Chain is a Delegated Proof of Stake blockchain based on Cosmos used as an example of the storage layer of the Request protocol

A Cosmos blockchain is a Delegated Proof of stake blockchain. Users delegate their fund to validators that will run the blockchain. The Request protocol will store the blocks to Request Chain and pay a fee that will be sent to the delegators and validators.

This version is a PoC

How does it works

This repo contains the modules rcd and rccli

Implementation of the storage layer

The new storage layer of Request protocol send API request to the rccli server.

github.com/ltacker/request-chain-storage

Testing

A fork of the Request Node has been created to use the new storage layer.

github.com/ltacker/request-node

This repo contains a docker-compose file that simulates a network with one validator and two, well funded, accounts. The network can be launched with the command:

docker-compose up

Then, you can create and update request with request-client.js to the node running on localhost:3000

IN PROGRESS

• Implementing Pegzone for ERC20 to allows usage of the REQ token to pay fees (https://github.com/cosmos/peggy)
