+- The size of the transaction, in bytes, exceeds the maximum transaction size as specified in the consensus parameters. The size of a transaction is calculated as the sum of the sizes its static and dynamic parts as determined by canonical serialization.   
 
 When serializing a transaction, fields are serialized as follows (with inner structs serialized recursively):
 
 1. `uint8`, `uint16`, `uint32`, `uint64`: big-endian right-aligned to 8 bytes.
 1. `byte[32]`: as-is.
 1. `byte[]`: as-is, with padding zeroes aligned to 8 bytes.
 
-When deserializing a transaction, the reverse is done. If there are insufficient bytes or too many bytes, the transaction is invalid.
