Use case title	[FR0100] Sending the instruction to the Iroha network
Preconditions	The user has an account in the Iroha network The user has prepared the command The user has permissions to execute the instruction The Iroha network is working in normal condition
Use case flow	The user sends the instruction to the Iroha peer through the API The Iroha peer receives the instruction and validates its contents The Iroha peer checks that the user's account have enough permissions to run the instruction The Iroha peer executes the instruction by applying it to the current block The Iroha peer returns the result of the operation to the user
Postconditions	The instruction is successfully executed and applied to the network state
Alternative flow	On step 4, if the current user's account is multi-signature, the result of instruction will be applied to the block-store only when the number of signatures will reach the current quorum value. In other case, the Iroha peer will return "pending" status as a response on step 5.
Exception flow	On step 2, of the instruction has invalid structure, the Iroha peer returns an error message with description to the users and stops the flow On step 3, if the user's account does not have required permissions, the Iroha peer returns information about that error and stops the flow

Use case title	[FR0105] Sending instruction and subscribing to the status of finalization
Preconditions	The user has permissions to execute requested instruction
Use case flow	The user prepares the instruction parameters according to his/her needs The user sends the instruction into the Iroha peer (<<includes>> FR0100) The user uses the same connection for obtaining the status of the instruction finalization The Iroha peer sends updates about the instruction finalization status to the user The user receives the "successfully finalized" status about the instruction
Postconditions	The instruction is accepted and finalized in the block-storage The user did not spend additional resources for redundant network connections and requests
Alternative flow
Exception flow	At Step step 4 if the instruction cannot pass the validation, the user would not get the "successfully finalized" status; instead, he/she will get the "invalid instruction" status. At Step step 4 if the network is in "bad" condition, the user would get the "successfully finalized" status eventually, when the network will return in a "good" state.

Use case flow	The user obtains the current list of pending instructions (<<include>> FR0203) The user finds information about all instructions that can be signed by his/her signatures The user signs one or more instructions using one or more available key pairs The user sends signed instructions to the Iroha peer (<<include>> FR0100)
