Reseeding module

Implements reseeding logic for RandApp application.

How it works

  • Participants sends seeds to the module as a transaction using the MsgSeed message:
type MsgSeed struct {
	Sender sdk.AccAddress
	Seed   []byte
}
  • Module stores those messages until you get a polka (2/3 + 1) votes for a given seed. Then the seed will be transferred to the Tendermint Consensus by calling the EndBlock() function
  • Multiple seeds may be competing for a polka; as soon as one seed gets enough votes and gets transferred to Tendermint, all loser seeds are deleted.

Example of seed sending

./${YOUR_APP_CLI_BIN} tx reseeding send ${YOUR_SEED} --chain-id=${YOUR_CHAIN} --from ${ACCOUNT}

Note that there is a reseeder script implemented by corestar.io that implements a bitcoin last-block-hash based seed.
