// Validate validates the given envelope corresponding to a transaction with an endorsement
// policy as given in its serialized form.
// Note that in the case of dependencies in a block, such as tx_n modifying the endorsement policy
// for key a and tx_n+1 modifying the value of key a, Validate(tx_n+1) will block until Validate(tx_n)
