No Empty Blocks
|

---------------
|

|

This much requested feature was implemented in version 0.10.3. While the default behaviour of ``tendermint`` is still to create blocks approximately once per second, it is possible to disable empty blocks or set a block creation interval. In the former case, blocks will be created when there are new transactions or when the AppHash changes.

Note also that the ``pub_key`` (the public key) in the

The genesis file contains the list of public keys which may participate

in the consensus, and their corresponding voting power. Greater than 2/3

of the voting power must be active (ie. the corresponding private keys

we do not recommend having voting powers greater than 10^12 (ie. 1 trillion)
