CoreStarIO RandApp

CoreStarIO RandApp is Cosmos-based SDK, designed for easier building blockchain applications using on-chain DKG algorithm in Golang.

More about cosmos-sdk.

Notable source code files to check out about DKG:

1. https://github.com/corestario/tendermint/blob/dcr-random/types/random.go
2. https://github.com/corestario/tendermint/blob/dcr-random/consensus/dkg.go
3. https://github.com/corestario/tendermint/blob/dcr-random/consensus/dkg_dealer.go

On-chain DKG works the same way as the off-chain version but writes its messages to blocks, which allows us to slash a validator that refuses to participate in a DKG round.

More about DKG and lib, which implements corresponding algorithm see dkglib.

Requirements:

• Tendermint (corestario fork)
• DKGLib
• Cosmos-utils
• Cosmos-sdk (corestario fork)
• Cosmos-modules (corestario fork)

Running a local-testnet

Ensure that you have docker!

Ensure that dkglib, tendermint, cosmos-sdk and cosmos-utils, modules folders are next to your randapp folder!

It is necessary for building docker images and starting testnet!

Example:

/ home

**/ projects

****/ randapp

****/ dkglib

****/ tendermint

****/ cosmos-sdk

****/ cosmos-utils

****/ modules

Run a local-testnet:

sudo rm -rf ./build && sudo make build-docker-randappdnode && make build-linux && sudo make localnet-stop && sudo make localnet-start-without-bls-keys

How to view logs on a randapp node:

docker logs -f randappdnode0

CLI commands

Randapp has only one type of messages which could be sent from cli - seeds (implement in Modules)

Send seed

randappcli reseeding send "SEED_BYTES"

Sending native MsgSendDKGData type from a cli or REST is not implemented due to unnecessary
