The easiest way to generate this data is to copy ~/.tendermint_test/somedir/* to ~/.tendermint
|
|
and to run a local node.
|
|
Be sure to set the db to "leveldb" to create a cswal file in ~/.tendermint/data/cswal.

If you need to change the signatures, you can use a script as follows:

The privBytes comes from config/tendermint_test/...
