  1. An action is an atomic behaviour in a transaction.
    An action can be explicit or implicit.

  2. Explicit actions:

    • are included explicitly in the list of action of the transaction;
    • contain the actual payload data to be executed as part of the transaction.

    Implicit actions:

    • are executed as a result of an explicit caller action within the transaction;
    • work within the same scope of permissions of the caller action.

  3. An action define an atomic behaviour in a transaction.
    A transaction contains a group of actions that execute automatically,
    in a certain order, in a decentralized application.

  4. A transaction receipt is created after the execution of all the actions of the transaction (and after the
    creation of the relative action receipts). It includes:

    • the result of the transaction;
    • the amount of CPU billed;
    • the total NET storage used.

    Receiving the transaction receipt means that the transaction has been executed.
    The relative results are written in the receipt.

What’s an action?
Atomic behaviours are defined by the actions, actions can be explicit or implicit. Explicit actions are created within a smart contract or generated by application code. An action requires authorization by one or more actors previously created on the blockchain. Unless an action that forms a blockchain transaction succeeds, one by one in a predefined order, it will fail.

What’s the difference between explicit actions and implicit (or inline) actions?
Actions can be created explicitly within a smart contract, a given actor: action pair requires an explicit minimum permission. Explicit actions are present in the signed transaction.

Implicit action although defined in the smart contract but are generated by an explicit action within a transaction requiring an implicit action.

What’s the difference between an action and a transaction?
A group of actions form the transactions. Action are the behaviours within the smart contract.

What is a transaction receipt and what does it mean to receive it?
the transaction receipt is created after the generation of the action receipt for the transaction.

The transaction receipt summarizes the result of the transaction (executed, unexecuted, failed, deferred, expired, etc.), including the actual amount of CPU billed in microseconds, and the total NET storage used

  1. In EOS, an action is an atomic behaviour, or in other words a single, indivisible operation.

  2. An explicit action is one that is included in the “list of actions that form a transaction”.
    An implicit (inline) action is generated as a result of an explicit action being executed. They are executed in the same transaction as the explicit actions, but are not propagated throughout the network.

  3. An action define behaviours in a smart contract.
    A transaction defines a set of actions on the blockchain.

  4. A transaction receipt “summarizes the result of the transaction”. It contains:

  • status ( {executed, soft_fail, hard_fail, delayed, expired} ): result of transaction execution attempt
  • cpu_usage_us (uint32_t): total CPU used in microseconds
  • net_usage_words (unsigned int): total NET used in 64-bit words
  • trx (variant): holds transaction ID or packed transaction

To receive a transaction receipt is to have all action receipts generated - in other words, all actions executed - for the transaction in question.

  1. What is an action?

An action that is implemented as C++ is an atomic behavior written within a smart contract to define the function of the contract; such as, implementation for account creation, producer voting, token operations, extend, replace, or disable the functionality.

  1. What is the difference between explicit actions and implicit (or online) actions?

Explicit actions and implicit (or inline) actions are different in the way that they are executed by the ESOSIO software. Explicit actions are presented in the signed transaction and are included in the actual list of actions. They are encoded and contain the actual payload data associated with an action to be executed as part of a transaction.
On the other hand, Implicit (or inline) actions are generated by an explicit caller action within a transaction as a side effect of processing a transaction. Implicit (online) action is required for the caller action to continue and work within the same scope and permission of the caller action, and are executed within the same transaction.

  1. What is the difference between an action and a transaction?

An action can be authorized by one or more actors previously created on a blockchain. An action can be created explicitly within a smart contract, or generate implicitly by application code.
A transaction is a group of actions that are executed atomically within a decentralized application and is referred to as a transaction blockchain.

  1. What is a transaction receipt and what does it mean to receive it?

A transaction receipt is all the action receipts that are generated after all actions included in the transaction are executed and a corresponding action receipt is produced for each action.
The transaction receipt means that the transaction is completed. It summarizes the results of the transaction where the transaction was successful, or not.

  1. Actions are the individual steps within a transaction that are generated explicitly within the contract or implicitly by the application code.
  2. Explicit actions are generated by the contract where implicit actions are side-effects of processing a transaction and are determined by the application code.
  3. A transaction consists of several actions.
  4. A transaction receipt is created when all of the action receipts have been created, so it means that the transaction either succeeded or failed.

  1. An action is a method performed within a smart contract.
  2. Explicit actions are defined within the code whereas implicit actions happen due to the execution of the code.
  3. A transaction contains actions whereas one action does not constitute a transaction.
  4. It signifies that a transaction was attempted and what the outcome of it was along with how much CPU and storage it consumed.

  1. What’s an action?

An action represents a single operation, whereas a transaction is a collection of one or more actions.

  1. What’s the difference between explicit actions and implicit (or inline) actions?

The main difference between explicit and implicit actions is the fact that implicit actions are not included in the actual transactions propagated through the network and eventually included in a block

  1. What’s the difference between an action and a transaction?

  1. An action is whereby a single operation is equal to a single or number of actions.

  2. The difference between an explicit action and implicit or (inline) action is that inline actions are not included in a block, they are implicit. Explicit actions are included in the actual list of actions that form a transaction and are encoded as action instances.

  3. The difference between an action and transaction is due to the fact that “Actions” define atomic behaviours within a smart contract & “Transactions” define groups of actions that execute atomically within a decentralised application.

  4. A transaction receipt is whereby a transaction has been completed with no error containing both the block number and transaction hash. However, this indicates only that a block producer has accepted the transaction and does not mean that the transaction is confirmed only that the block producer has accepted the transaction.

  1. What’s an action?
    Action defines atomic behaviour inside a smart contract where individual steps within a transaction are generated explicitly (within a contract) or implicitly (by the application code).

  2. What’s the difference between explicit actions and implicit (or inline) actions?
    Explicit actions are directly included in the list of actions to be executed as part of the transaction. They contain the actual payload data associated with a transaction.
    Implicit actions are the side effects of processing a transaction and are determined by the application code. They work within the same scope and permission of the caller action and are executed within the same transaction.

  3. What’s the difference between an action and a transaction?
    A transaction is made up of a set of actions (which are coded behaviours) which are then executed to determine the functionality of smart contracts and dapps.

  4. What is a transaction receipt and what does it mean to receive it?
    In short, a transaction receipt outlines the result of a transaction.nIt includes the billed amount of CPU (computation) which is measured in microseconds, as well as the total NET storage use.

2.Explicit actions are present in a signed transaction and implicit(inline) actions are side effects of processing transactions. The key difference is that inline actions are not included in the actual transactions block.
3. Actions define the actual behaviours in the contract, while transactions are created at the application level. Actions are implemented as C++ methods within the derived class and transactions are dynamically within a EOSIO applications. Signature validation is at the transaction level.
4.A receipt is generated from the return of the public keys and the creation of the transaction instance on the blockchain. All generated actions are included in the receipt, generated during transaction finalization. The receipt is returned once the transaction is final and all action receipts have been finalized.

  1. What’s an action?
    Actions specify and define the actual behaviors of the contract. There are two types of actions that can be created explicitly within a smart contract, or generated implicitly by application code.

  2. What’s the difference between explicit actions and implicit (or inline) actions?
    Explicit actions are included in the actual list of actions that form a transaction and may contain the actual payload data associated with the action to be executed as part of the transaction. Whereas implicit (inline) action is generated as a result of an explicit caller action within a transaction (or another inline action, if nested) that requires that implicit action to perform an operation for the caller action to continue. As such, inline actions work within the same scope and permissions of the caller action. Therefore, inline actions are guaranteed to execute within the same transaction.

  3. What’s the difference between an action and a transaction?
    Actions define the actual behaviours of the contract and each action included in the transaction are executed. The transaction goes through multiple validation processes at various levels before it is dispatched for execution.

  4. What is a transaction receipt and what does it mean to receive it?

The transaction receipt summarizes the result of the transaction (executed, unexecuted, failed, deferred, expired, etc.), including the actual amount of CPU billed in microseconds, and the total NET storage used

  1. What’s an action?

Actions define atomic behaviors within a smart contract. An action can be authorized by one or more actors previously created on the blockchain. Actions can be created explicitly within a smart contract, or generated implicitly by application code. For any given actor:action pair there is at most one explicit associated minimum permission. If there are no explicit minimum permissions set, the implicit default is actor@active . Each actor can independently set their personal minimum permission for a given action. Also, a complex but flexible authorization structure is in place within the EOSIO software to allow actors to push actions on behalf of other accounts.

  1. What’s the difference between explicit actions and implicit (or inline) actions?

There are two types of actions involved in a transaction. They mainly differ in the way they are executed by the EOSIO software:

  1. Explicit actions, which are present in a signed transaction (see 2. Transaction Instance).
  2. Implicit (inline) actions, which are created as a side effect of processing a transaction.

Implicit (inline) actions are also defined in smart contract code, just like explicit actions. The key difference is that inline actions are not included in the actual transactions propagated through the network and eventually included in a block; they are implicit.1.1.1. Explicit Actions

Regular or explicit actions, as their name implies, are included in the actual list of actions that form a transaction. Explicit actions are encoded as action instances before being pushed into the transaction. Explicit actions also contain the actual payload data, if any, associated with the action to be executed as part of the transaction.

Implicit Actions

An implicit (inline) action is generated as a result of an explicit caller action within a transaction (or another inline action, if nested) that requires that implicit action to perform an operation for the caller action to continue. As such, inline actions work within the same scope and permissions of the caller action. Therefore, inline actions are guaranteed to execute within the same transaction.

  1. What’s the difference between an action and a transaction?

An action prepares and checks permissions and the ability to perform the transaction. The transaction is the actual sending of the money.

  1. What is a transaction receipt and what does it mean to receive it?

After all action receipts are generated for the transaction, a transaction receipt is finally created and pushed into the signed block, along with other transaction receipts included in the block. The transaction receipt summarizes the result of the transaction (executed, unexecuted, failed, deferred, expired, etc.), including the actual amount of CPU billed in microseconds, and the total NET storage used.

An action is:
Define atomic behaviours within a smart contract. Actions are implicit and explicit authorizations is a smart contract. Execution of a task that leads to creating a transaction

Difference between explicit actions and implicit(or inline) actions:
They mainly differ in the way they are executed by the EOSIO software.
Explicit actions are created within a smart contract and implicit actions are created by application code.

Difference between an action and a transaction:
An action is an instance of a transaction while the transaction is the validating process of action or actions.

What is a transaction receipt and what does it mean to receive it?
Once a transaction is completed, a transaction receipt is being generated. It means that a node confirmed the transaction to be errorless. But the transaction hasn’t been confirmed and still needs to be tested and verified by the rest nodes.
