MODULE:UTILIZING THE FREE STORAGE OF A SMARTPHONE AS AN ASSET
MODULE is a blockchain-based platform designed to utilize the free storage of smartphones, PCs, servers, etc. as an asset. Using the MODULE platform, one will be able to participate in mining even from a smartphone. Servers and enterprises can also participate in mining.
Module’s consensus (mining) algorithm makes it possible to earn rewards by lending out storage space. As the storage capacity of devices progresses and expands, one can expect the various services offered to expand. In addition to issuing new original coins, users will also be able to develop Dapps (Decentralized applications) on the platform.
THE MODULE PLATFORM
MODULE employs a new transaction approval algorithm. It is a new technology platform that enables everyone to participate in mining, even from a mobile device. In addition to building DApps, users will also have the ability to issue new currencies on the platform.
MODULE focused on mobile devices as a way to solve problems such as the power consumption concerns caused by cryptocurrencies and their centralization. The Module project announces the future of mining with such energy-efficient and easy to use devices such as smartphones and tablets. By releasing the capacity of your device, you will be able to earn rewards, which will vary depending on the capacity of free storage, utilization time, space and transaction type. In other words, lending of storage space will make you eligible for compensation. The platform also has great potential as a platform that can provide other distributed application services.
MODULE App — data storage service
MODULE is suitable for storage of sensitive information because its distributed storage keeps data in fragments in many different places. It can be used to store information that should be kept secret from others.
In particular, by storing information in a distributed store like MODULE, one can enhance information security through “secret sharing”. In other words, if sensitive information is divided into fragmentary pieces of information and stored in separate places, information cannot be reproduced with only one fragment, but if several pieces are gathered, the information can be reproduced. This Secret Sharing method will be used in blockchain, and to build secure cloud storage for the safe storage of sensitive information.
The technique for concealing documents recorded in blockchain through the management of secret sharing keys has already been developed. One obstacle to utilizing blockchain to handle sensitive information was the fact that information on blockchain must be disclosed to the entire community of users. However, by combining blockchain technology and secret sharing, one can expect higher security and convenience. In this way blockchain can be used in various fields such as finance, distribution, in the supply chain, official document management, etc.
MODULE TECHNOLOGY
About the PoSTT block chain mechanism
The PoSTT blockchain was born from the idea to introduce blockchain technology to existing cloudbased servers. The existing client-server solution is plagued by problems of server management costs and hacker attacks. In a client-server solution, the user’s data are stored in the client’s server, and data may leak or be destroyed if the server is attacked. However, this data security problem can be resolved by distributing and storing the user’s data using the P2P method on blockchain. Besides, data can be stored at a lower cost.
Nodes participating in the PoSTT blockchain
* Node that is requesting data storage (Verifier): a node that attempts to divide data and store it in the P2P network
* Node that provides storage capacity (Farmer): a node that provides storage capacity on the P2P network and receives rewards (coins) for data storage
* Node which maintains the blockchain (Miner): a node that verifies the transaction history and smart contract, generates blocks and maintains the blockchain.
Mechanism of the PoSTT blockchain
1. The PoSTT blockchain has its own coin.
The Verifier will pay the cost of storing the data with this coin, and the Farmer will receive coins as compensation for providing storage capacity to store the data. This means that the PoSTT blockchain has a transaction function associated with the sending and receiving of coins.
2. The Verifier and the Farmer also conclude a smart contract related to storing each other’s data, so that the Verifier and the Farmer can safely perform data processing. In other words, blockchain stores smart contracts related to transactions with coins (transmission/reception) and data management. To do so, the Farmer possess the address of the token for the smart contract. There is also a bridge server which exists separately from blockchain.
3. Finally, there is the Miner, who maintains the blockchain.
The Miner:
1) checks the content of the smart contract related to the transaction of created coins and uploading/downloading the data, and
2) generates the block. The Miner implements the Farmer’s calculation logic for the compensation payment and issues coins to the Farmer when the block is created.
4. Bridge server (hereinafter referred to as the Bridge)
The Bridge forms the connection between the Farmer and the Verifier. The Bridge stores only MetaData, not the personal data of the Verifier. The Bridge periodically checks the status of the Farmer and monitors the accuracy and validity of the data stored in the Farmer’s network, the status of the data and the payment relationship. By providing API, the Bridge gives other blockchain developers the opportunity to extend various functions of the PoSTT blocks. Using this API, the developer can check the current state of the blockchain state and so on, and develop various programs using the PoSTT blockchain. The Bridge also includes algorithms such as file status, setting the criteria for the selection of a Farmer, and so on. In addition, the Merkle Tree function will establish mutual trust between the Farmer and the Verifier and serve as verification of file accuracy.
ABOUT GAS AND THE PoSTT FEE
All transactions and smart contracts processed in the PoSTT blockchain can be seen as scripts. For example, looking at a simple transaction, transactions can be seen as a combination of opcodes. The meaning of the opcode is the minimum unit constituting the script of the transaction. As an example, when we see the instruction “Push PublicKey”, it is a simple command to enter the Public Key to the stack.
In this case, the transaction, being a combination of instructions as seen above, can issue the verification code of the transaction as a script. This script is executed by the virtual engine on blockchain, and can confirm the accuracy of the transaction as the execution result of the script.
Here, Gas is the amount of coins necessary to execute the opcode, which is the smallest unit constituting the script of the transaction. Both transactions and smart contracts can be seen as a combination of opcodes (i.e. as scripts).
In other words, Gas can be seen as the cost of processing the opcode, which is the smallest execution unit constituting the script.
Why is Gas necessary?
When there is no Gas, that is, when there is no cost to execute the opcode, a malicious attacker can destroy the virtual engine on blockchain by inserting code that will repeat infinitely in the script. By adding a cost-per-execution unit to prevent this, it is possible to prevent various malicious attacks by adding expenses proportional to the length of the script command.
