 ## Types of messages
 There are three types of messages:
- * external—messages that are sent from outside of the blockchain to a smart contract inside the blockchain. Such messages should be explicitly accepted by smart contracts during so called `credit_gas`. If the message is not accepted, the node should not accept it into a block or relay it to other nodes.
- * internal—messages that are sent from one blockchain entity to another. Such messages (in contrast to external) may carry some TON and pay for themselves. Thus, smart contracts that receive such messages may not accept it. In this case, gas will be deducted from the message value.
- * logs—messages that are sent from a blockchain entity to the outer world. Generally speaking, there is no mechanism for sending such messages out of the blockchain. In fact, while all nodes in the network have consensus on whether a message was created or not, there are no rules on how to process them. Logs may be directly sent to `/dev/null`, logged to disk, saved an indexed database, or even sent by non-blockchain means (email/telegram/sms), all of these are at the sole discretion of the given node.
