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.

Example:

**/ projects

****/ randapp

****/ dkglib

****/ modules

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

docker logs -f randappdnode0

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

randappcli reseeding send "SEED_BYTES"

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