In developing the blockchain backbone for our ecosystem, we have selected Solana as our primary Main-Net. This decision is grounded in Solana's technical capabilities, which align closely with the demands of our C2E (Collect-to-Earn) model and broader blockchain business model. Solana is the ideal Main-Net for our blockchain ecosystem due to its high throughput, low transaction costs, fast finality, robust security, ecosystem compatibility, and energy efficiency. By leveraging Solana’s advanced capabilities, we can build a scalable, secure, and sustainable blockchain infrastructure that supports our C2E model and drives our mission to create a greener, more equitable future.
One of the most critical requirements for our blockchain ecosystem is the ability to handle a high volume of transactions quickly and efficiently. Solana excels in this regard, offering unparalleled scalability with its Proof of History (PoH) consensus mechanism, which can process up to 65,000 transactions per second (TPS). This high throughput ensures that our ecosystem can scale to accommodate millions of users and transactions, including COTC token exchanges, oil mining compensations, and carbon credit allocations, without suffering from congestion or delays.
Cost efficiency is vital for the success of our C2E model, where microtransactions will be a common occurrence. Solana offers extremely low transaction fees, typically averaging around $0.00025 per transaction. This is crucial for ensuring that participants in our ecosystem, particularly those from underdeveloped regions, can engage in transactions without being burdened by high costs. The low fees also make it feasible to implement and maintain a rewards system that incentivizes small-scale actions, such as waste plastic collection and community engagement.
Solana’s network provides near-instant transaction finality, with block times averaging around 400 milliseconds. This rapid confirmation time is essential for maintaining a seamless user experience within our ecosystem. Whether it’s issuing COTC tokens, logging environmental data, or processing oil mining rewards, the speed of Solana ensures that all transactions are settled almost instantaneously, reducing the risk of double-spending and enhancing the overall efficiency of the network.
Security and decentralization are paramount for the integrity of our blockchain ecosystem. Solana’s architecture is designed to maximize both. It utilizes Gulf Stream (a mempool-less forwarding protocol) and Turbine (a block propagation protocol), which help distribute data more efficiently across nodes, contributing to greater network security. Additionally, Solana’s growing number of validators (over 1,000 active validators) enhances the decentralization of the network, reducing the risk of centralization and ensuring that the blockchain remains resilient against attacks.
Solana’s compatibility with various tools and frameworks makes it an attractive platform for developers. The Solana ecosystem includes comprehensive support for smart contracts and decentralized applications (dApps), which are crucial for implementing our C2E model, community governance, and carbon credit system. Furthermore, Solana’s active developer community and extensive resources ensure that our technical team can efficiently build and deploy the necessary components of our blockchain ecosystem.
Given our commitment to environmental sustainability, the energy efficiency of our blockchain infrastructure is a significant consideration. Solana’s consensus mechanism, which combines Proof of History with Proof of Stake, is designed to be more energy-efficient compared to traditional Proof of Work (PoW) systems. This lower energy consumption aligns with our goal of minimizing the environmental impact of our operations while supporting the broader adoption of green technologies.
CityOil dApp is a robust decentralized application built on the Solana blockchain, tailored to drive the CityOil ecosystem by enabling a variety of functions including COTC coin transfers, C2E (Collect-to-Earn) mining, donations, staking, loans, and decentralized governance (DAO). This dApp is designed to transform waste plastic collection into a profitable venture, where participants earn COTC tokens as rewards. It integrates blockchain technology to ensure secure, transparent, and efficient transactions, all governed by smart contracts. The user-friendly interface makes it easy for anyone to navigate and participate in the ecosystem, whether they're engaging in environmental protection activities, managing their digital assets, or contributing to community governance. CityOil dApp also plays a crucial role in expanding the CityOil mission globally, enabling a circular economy that promotes sustainability and economic empowerment. Through this innovative platform, CityOil is setting new standards for how technology can be leveraged to protect the environment while fostering economic growth and community development.



The COTC Ecosystem is a meticulously designed, integrated economy that benefits all stakeholders, including investors, collectors, government agencies, and the community. At its core, the ecosystem revolves around the COTC coin, which powers every transaction, from oil mining rewards to carbon credits. Collectors are incentivized through the C2E model, earning rewards for their efforts in waste plastic collection and contributing to environmental sustainability. Investors are rewarded with oil mining returns, while government and community stakeholders receive support funds, ensuring alignment with sustainable development goals. The ecosystem is governed by a decentralized autonomous organization (DAO), allowing stakeholders to participate in decision-making through proposals and votes. The integration of logistics, blockchain development, and operations management ensures a seamless flow of resources, creating a sustainable, profitable, and transparent system for all participants.
