Long: `This command is used to validate the completeness of state data corresponding specific to a specific root

It can operate at three levels:
|
|
|
|
"full" validates completeness of the entire state corresponding to a provided state root, including both state and storage tries
|
|
|
|
./eth-ipfs-state-validator validateTrie --config={path to db config} --type=full --state-root={state root hex string}
|
|
|
|
|
|
"state" validates completeness of the state trie corresponding to a provided state root, excluding the storage tries
|
|
|
|
./eth-ipfs-state-validator validateTrie --config={path to db config} --type=state --state-root={state root hex string}
|
|
|
|
|
|
"storage" validates completeness of only the storage trie corresponding to a provided storage root and contract address
|
|
|
|
./eth-ipfs-state-validator validateTrie --config={path to db config} --type=storage --storage-root={state root hex string} --address={contract address hex string}
