tx_spammer

Tools to enable the semi-reproducible growth of a large and complex chain over RPC, for testing and benchmarking purposes

Usage:

./tx_spammer autoSend --config=./environments/gen.toml

The autoSend command takes as input a .toml config of the below format, the fields can be overridden with the env variables in the comments. It uses the provided key pairs and configuraiton parameters to generate and deploy a number of contracts with a simple interface for Puting to a dynamic data structure. It can then spam these contracts with Put operations at deterministically generated storage locations in order to grow the storage tries indefinitely and in a reproducible manner. Additionally, it can be configured to send large numbers of eth value transfers to a set of manually designated or deterministically derived addresses, in order to grow the state trie.

This process is semi-reproducible, in that given the same input it will generate and send the same set of contract deployment, eth transfer, and contract calling transactions. The precise ordering of transactions is not guaranteed, and uncertainty is introduced by the miner processing the transactions.
