blockNumber
string
The block number as a string in hexadecimal format or tags. The supported tag values include earliest for the earliest/genesis block, latest for the latest mined block, pending for the pending state/transactions, safe for the most recent secure block, and finalized for the most recent secure block accepted by more than 2/3 of validators. safe and finalized are only supported on Ethereum and Gnosis

Returns

array
The block traces, which have the following fields (please note that all return types are hexadecimal representations of their data type unless otherwise stated):
output
The data which is returned as an output encoded in hexadecimal format
stateDiff
It returns the information on altered Ethereum state due to execution of the given transaction
trace

action
The action to be performed on the receiver id:
from
The address of the sender
callType
The type of method such as call, delegatecall

subtraces
The traces of contract calls made by the transaction
traceAddress
The list of addresses where the call executed, the address of the parents and the order of the current sub call
type
The value of the method such as call or create
vmTrace
It is used to get a full trace of the virtual machine's state during the execution of the given transaction, including for any sub-calls
