43 - Transactions vs Messages Messages

Transactions vs Messages:

1. A transaction is produced by an EOA where an external actor sends a signed data package which either:

   1. triggers a message to another EOA where it leads to a transfer of value or
   2. triggers a message to a contract account where it leads to the recipient contract account running its code

2. A message is either:

   1. triggered by a transaction to another EOA or contract account or
   2. triggered internally within the EVM by a contract account when it executes the CALL family of opcodes and leads to the recipient contract account running its code or value transfer to the recipient EOA
