Dummy
There are two app's here: the DummyApplication and the PersistentDummyApplication.
DummyApplication
The DummyApplication is a simple merkle key-value store.
Transactions of the form key=value are stored as key-value pairs in the tree.
Transactions without an = sign set the value to the key.
The app has no replay protection (other than what the mempool provides).
PersistentDummyApplication
The PersistentDummyApplication wraps the DummyApplication and provides two additional features:
- persistence of state across app restarts (using Tendermint's ABCI-Handshake mechanism)
- validator set changes
The state is persisted in leveldb along with the last block committed, and the Handshake allows any necessary blocks to be replayed. Validator set changes are effected using the following transaction format:
val:pubkey1/power1,addr2/power2,addr3/power3"
where power1 is the new voting power for the validator with pubkey1 (possibly a new one).
There is no sybil protection against new validators joining.
Validators can be removed by setting their power to 0.

Functions ¶
func InitDummy ¶ added in v0.7.0
func InitDummy(app *PersistentDummyApplication)
InitDummy initializes the dummy app with some data, which allows tests to pass and is fine as long as you don't make any tx that modify the validator state
func MakeValSetChangeTx ¶
Types ¶
type DummyApplication ¶
type DummyApplication struct {
types.BaseApplication
// contains filtered or unexported fields
