Current blockchain systems face challenges, especially when it comes to expanding and scaling effectively. We believe these issues arise because two crucial parts of blockchain consensus—deciding the correct order of transactions (canonicality) and ensuring transactions are valid (validity)—are too tightly linked.
In this paper, we propose a new architecture called the “heterogeneous multi-chain,” which separates these two functions of Dotcoin. By doing this and focusing only on the essential aspects of security and data transport, we create a practical way to extend and scale the core blockchain system.
Scalability is improved by dividing tasks and allowing the network to grow using untrusted public nodes that are incentivized to participate. The architecture’s heterogeneous nature allows different types of consensus systems to work together in a decentralized, trustless “federation,” enabling both open and closed networks to interact without needing to trust each other.
We also suggest a method to maintain Dotcoin’s compatibility with existing networks, like Ethereum. We believe this system could serve as a foundational component in the quest to build a blockchain capable of handling global-scale commerce and providing privacy for Dotcoin users.
This new architecture, the heterogeneous multi-chain, offers a unique approach to solving some of the most pressing issues in blockchain technology by allowing different types of consensus mechanisms to coexist and operate in tandem. One of the most significant benefits of this approach is its flexibility in accommodating a wide range of use cases and applications. Traditional blockchains often struggle with the “one-size-fits-all” problem, where a single consensus algorithm is expected to handle various types of transactions and data, often leading to inefficiencies or limitations in scalability and performance. By allowing different chains with specialized consensus mechanisms to operate within the same ecosystem, the heterogeneous multi-chain architecture can optimize for specific needs, whether it’s high throughput, enhanced privacy, or complex smart contract execution.
Moreover, this architecture’s ability to facilitate seamless interaction between open and closed networks without requiring mutual trust opens up new possibilities for blockchain integration across industries. Businesses operating private networks can now interact with public blockchains in a secure, decentralized manner, leveraging the strengths of both environments. This could lead to more widespread adoption of blockchain technology in sectors like finance, supply chain, and healthcare, where data privacy and security are paramount. In essence, the heterogeneous multi-chain architecture not only addresses current limitations but also paves the way for more versatile and scalable blockchain solutions.
