Cryptocurrency and blockchain financing have been suffering from a black eye lately because the traditional form of crypto mining generally involves a high demand on the standard power grid.
And that drives up the need for more electricity consumption as well as the additional fuel sources needed to create that electricity. While some countries have focused on producing energy from solar or hydro sources, many other countries with significant crypto-mining operations rely on their power from dirty sources like coal and similar.
An Alternative to Polluting Crypto
Alternatively, imagine a cryptocurrency purposefully designed to be compatible with sustainable objectives and the environment. Instead of producing waste, the crypto coin produces value and net gain. There are no negative side effects and downstream losses. It can operate on a viable and valid blockchain network, the Binance network, and it still provides the exponential benefits of blockchain data transfer, value exchange and more. This is the concept with the GreenTrust token.
Originally put out on the Binance network in April 2021, the Green Trust token was intended to hit two goals right away: avoid creating more pollution and energy waste problems in its product, and boost computational capability. GreenTrust token is strategically focused on merging the power generation sector with cryptocurrency mining. Developing expertise and knowledge of green technologies, GreenTrust aims to bring renewable energy solutions for powering blockchain mining operations. Additionally, The GreenTrust network is committed to planting new trees to offset the minimal carbon footprint it does create, producing far more positive impacts than what typically occurs with other cryptocurrencies.
Making a Point on the Blockchain
The GreenTrust token is one of the few options that pushes the green economy proactively into the blockchain environment to stop carbon emission damage in the physical, real world. Further, every commitment and staking adds to the carbon sequestration with new trees adding oxygen and reducing greenhouse gases in real-time application. The other big currencies like Ethereum, Bitcoin and Ripple can’t say the same.
Granted, there are lots of choices on the Ethernet now for digital cryptocurrency investment and value staking. However, it’s time for financial digital power to go beyond just the basic purpose of producing gain and making a profit. It’s time to also push the blockchain to producing greater change than simply moving financial assets from one network to another. The GreenTrust token does exactly that, helping people engage blockchain in sustainability, reducing the negative effects of prior crypto mining, and helping preserve the world, maybe as a better place for the next generation at the same time.

Original Intention for Decentralized Cloud Storage System Design via MEMO
Nowadays, everyone is deeply surrounded by massive amounts of information. On the one hand, it does raise anxiety among people; on the other hand, there is no lack of useful information for those in need. Besides, almost every individual has the need for storing private data, especially for some organizations.
However, with the exponential explosion of data, people have found that the cost of existing data storage methods has increased correspondingly. In addition, frequent information security incidents also make people re-examine the existing data storage mode, and people look forward to a safer and more efficient new storage mode. Considering the above, the decentralized cloud storage based on blockchain has emerged.
Since the decentralized cloud storage system is deployed in a low-trust P2P network, there is no centralized third-party organization responsible for the management, and the storage devices are mostly idle edge devices offered by Providers, not proprietary storage servers. Therefore, for this application scenario, the decentralized cloud storage management system first faces system management problems, which are divided into system role management, storage market management, data maintenance management, etc. These management requirements are ultimately solved by smart contracts, so the management problems of smart contracts must also be solved.
1. Management of System Roles–Solve the Problem of Role Division
According to the needs of storage scenarios and functions, users in a decentralized cloud storage system are divided into three categories, which are defined as User (storage demander), Provider (storage provider) and Keeper (storage coordinator). Their functions in the system are stated as follows:
① User (Storage Demander): use storage service, including uploading data which is then saved by the storage node in the system, downloading and reading stored data according to needs.
② Keeper (Storage Coordinator): responsible for the function of information intermediary and management, including collecting the situation of storage provided by the Provider connected to it; collecting the evaluation information of the Keeper connected to it; seeking for the suitable Provider according to the User’s storage needs and challenging the Provider.
③ Provider (Storage Provider): provide storage space, including providing User with storage space, saving User’s data, keeping online to satisfy User’s requests for downloading and reading data at any time.
2. Management of Storage Market–How to Implement Decentralized Cloud Storage Service in MEMO System on Blockchain
The key application of Mamoriae is storage service, so the management of storage market is essential. With the help of Keeper, User finds some suitable Providers who provides the space and time for data storing. Keeper challenges Provider on a regular basis, so if there is a Provider found to fail, then the data repair function needs to be triggered. User downloads and reads its data from Provider when there is a need. According to the application scenario above, User needs to pay Provider for storing and downloading data and pay Keeper for information coordination and management.
If one of the three roles violates the storage rules, such as damaging data and refusing to repair, etc., a corresponding penalty mechanism is needed to maintain the normal operation of the system. How Keeper matches between User and Provider; how to pay according to the price after the storage service is established; how to solve it when faced with a request from a User to download data. These problems stated above are collectively referred to as the requirements of storage market management, so MEMO has designed a storage duration management solution for this.
3. Management of Data Maintenance–Solve the Problem of Data Maintenance
Decentralized cloud storage systems face the need for data maintenance and management. User’s data is stored on the selected Provider in the form of object storage, and the corresponding Keeper will challenge to ensure that the Provider saves the data completely and correctly. However, this mechanism lacks credibility. All Keepers facing the same User may act dishonestly and provide false challenge results.
In addition, the user’s metadata information is stored on the corresponding Keeper and synchronized between the Keepers. This can solve the problem of the unbalanced load of metadata information or node failure in centralized cloud storage. However, this method does not completely guarantee the correctness of the metadata information because the Keepers may negotiate and commit evil together. Therefore, based on the decentralization and trustworthiness of the smart contract, important information related to the stored data can be stored in the smart contract, so as to facilitate the maintenance of the correctness of the data.
In order to maintain data security and integrity, various mainstream cryptographic technologies, such as symmetric encryption and decryption, anti-collision hash functions, and digital signature technologies, are applied to meet strict data privacy and integrity requirements. Cryptography technology and data redundancy and repair technology will provide the system with sufficient flexibility to tolerate various possible software and hardware failures and small-scale malicious attacks, such as attempts to invade the equipments of Keeper, Provider and User, thereby tampering, destroying, or disclosing data and information. At the same time, MEMO uses proven POW and more innovative POS technology, supplemented by third-party security tools to further enhance system security.
Management of Smart Contract
One of the key issues in building a large-scale decentralized cloud storage system is the efficient management of system roles and their relationships. As mentioned above, the system has requirements for role management, storage market management, data maintenance and management.Also,these requirements ultimately need to be realized by smart contracts. Therefore, smart contract management is the basis for the realization of the above three types of management requirements. Contract management runs through the entire operating system.
How to Call the Smart Contract?
After the smart contract is deployed, the user needs to use the contract instance to call the methods in the contract. The contract instance can be constructed by the contract address. For some contract functions that need to change the on-chain state information, a specific user identity is required to call; and for those contract functions that obtain the on-chain state information, any user identity can call. Therefore, the system has management issues such as storage and acquisition of contract addresses.
In the MEMO system, the account is first registered as a certain role, such as User. During this process, the address and User role of the account will be saved in the role module on smart contract. When the account is online, the role smart contract will be called. Get your own role, and get the corresponding service according to it. The account determines the role that it wants to play in the system based on its own storage requirements, conditions, etc. After the user goes online, the role information of the account is obtained from the role module.
Different roles have different functions, and role information also needs to be saved. The traditional method is to save the user’s role, address and other information in the database, which is managed by the specific company that owns it. In the decentralized scenario in MEMO system, according to the characteristics of the account address that uniquely identifies users, smart contracts are used to manage system role information. In the initial stage of use, the Keeper of each User is randomly matched by the system. After the Keeper has accumulated certain data about the availability and reliability of the Provider, a scoring system can be built to match the Provider and the User, which can greatly reduce the transaction time.
Demand analysis is a prerequisite for design and implementation. Based on the above management needs, MEMO has designed multiple modules to solve the problems of role division, storage service implementation data maintenance, and contract invocation. It is these that constitute the solidity of the open-source decentralized cloud storage system of MEMO.
