Open Problem Statements

Below we have listed the problem statements which are open to all. In order to participate, create a proposal in the format specified & make a pull request.

Task 1: Optimize delegated proof of stake (DPoS) consensus

In DPoS, Restriction numbers of node make its more centralized while large number of nodes makes the system very slow. We are proposing Optimization in DPoS consensus. XinFin DPoS Development progress detail at:

Task 2: Cross Blockchain Interoperability of XinFin Network with R3 Corda Network

As a R3 Corda Partner XinFin going to provide bridge to access public state on XinFin Blockchain to R3 consortium of over 200+ financial institutions. We need to Create Bridge between XinFin Network and R3 Corda. This will create the ability to relay R3 Corda a limited set of data and transactions from privacy channels to the XinFin public network.

At the time of development of bridge keep below mentioned Standard:

a. ISO20022 Data Standard.

b. ERP data Standard.

c. Open Banking Standard.

d. SWIFT Data Standard.

Task 3 : XDCE Token Staking Function.

A staking mechanism requires users who offer compute power or other resources to the service takers in the ecosystem to put up a portion of their tokens in order to do so. If a user has no tokens to stake, but wants to support the network by providing resources they must purchase them. In exchange for staking their tokens and providing the service a financial reward is received. By forcing providers to take a financial risk you are weeding out bad actors.
