# Multiple-Valued Logic Modelling for Agents Controlled via Optical Networks
## 4 Conclusions  
Modern fiber optics can become the base for the distant control of unmanned robotic agents and MASs. However, mass and inexpensive unmanned mobile hardware agents can scarcely be realized as trusted nodes; moreover, they should interact with network nodes that have different levels of trust. As a result, traditional memory data storage becomes the vulnerable component of a mass autonomous robot, and the situation cannot be radically changed for the modern level of quantum memory technologies. That is why, for the reliable work of autonomous mass agents, they should more closely interact with partner network nodes and agents, which can be used for mutual monitoring and as distributed backup storages of critical data necessary in case of breakdowns and attacks. The trend is also to involve different estimates of trust and various verification procedures. Thus, the problem of illegal modifications of data in mass unmanned robots makes the actual design of complicated verification procedures based on AI and multiagent models difficult.  
In the present paper, the use of some of the methods designed earlier for the blockchain and distributed ledgers and to applying logic analogs of the linked list and a distributed ledger scheme are proposed. As a robotic version of a ledger is aimed at technical tasks, the approval of data can be realized as simple majority voting instead of expensive proof-of-work schemes from the blockchain.  
In order to integrate classical and quantum verification protocols with digital images and other possible data structures, the AGA logic model of a linked list is proposed for agents, autonomously interacting with network nodes. This model uses the AGA function for the logic modelling of two entries, attributed to the time parameter and random hash values assigned collectively by partner nodes. Such a scheme simplifies the integration of complicated quantum and classical verification protocols, such as the protocol PU for position-based verification, and makes the earlier proposed RO schemes for hashing more interesting.  
Keys for access to backup storages in external nodes are proposed to be sets of random hash values, assigned by network partners involved with the pool as verifiers, or by entries written in the special format of the data. Such functions that include entries and hash values can be directly used for data extraction from distributed storages. Entries in these functions are intended to approve licenses, credentials, and other critical data for the unmanned work of agents.  
The method of \"prohibited\" product terms is proposed in order to prevent illegal modification of the logic ledger by the minimization of logic expressions, which may be applied for the shortening of the ledger's length and time computing.  
Initial testing was held for MVL programs necessary for agents and logic ledger design, stimulating the choice of specific architecture for involved agents, which is necessary for full-scale testing of the proposed method.
