The Need For Layer 3 on the Internet of Value

Layer 2 projects such as Lightning Network, Raiden Network, Trinity Network (payment channels), as well as Celer Network and Counterfactual (generalized state channels) belong to state channel projects. Meanwhile, Plasma, RSK, and Liquid use side chains to solve the problem of scalability for basic blockchain systems. But, as we discussed above, none of them solves our problem number 4 — the problem of interoperability. And although projects such as LN and Raiden state that they will in the future, that’s quite a challenge for any project focused on a specific DLT. The fact is that the provision of atomic untrusted transactions between two different blockchains is an extremely difficult task due to differences in technological approaches and the misalignment between project schedules. But why is this such a serious problem? Let’s try to imagine a physical world without interoperability, using some historical examples. In the 19th century, the United States experienced a boom in railway construction. Several large companies were engaged in the construction and development of a network of railways. But imagine the consequences if each of these companies had built a railroad to their own standards, incompatible with the others? Different track gauges, different rail shapes, etc. Perhaps one of these hypothetical widths or shapes would be more optimal than that used today, or some of these standards would be better suited for specific tasks. However, each company would have to forge its own line to each point, while producing separate cars and locomotives compatible with their proprietary standards, and so on. Instead of one universal railway station in each village, we would have to build several different ones for each of the incompatible railway networks. What do you think would happen in this case? Would the railroad still have become an essential conduit for the development of new territories, the improvement of economic ties between regions, etc.? In other words, how would a lack of interoperability have affected the adoption of this technology? Some developers of Layer 2 solutions state that they plan to solve the problem of interoperability in the future. But today, nevertheless, they continue to improve their projects focusing on a particular blockchain; at best, on compatible blockchains (for example, Bitcoin forks, or smart contract projects similar to Ethereum, etc.) On the other hand, should Layer 2 projects even try to solve the problem of interoperability? In our opinion, this problem belongs to a different level; namely, Layer 3. And this means that it’s better to solve it separately and with the help of more specialized approaches. It might be appropriate to draw an analogy here with the development of the Internet itself. The Internet has its own technological layers, each of which performs a specific function: - Link layer: various technologies and data transfer protocols between devices on the local network, for example, Ethernet, WiFi, PPP, HDLC, etc. - Network layer: protocols that transfer data over a wide area network. - Transport layer: protocols responsible for the complete delivery of data, etc. The peculiarity of the Network layer is that it is as abstract as possible from lower-level protocol technologies. Its task is to ensure the possibility of global data transmission, or, in our terms, to ensure interoperability for various devices and local area networks (LANs), binding all of them into a single global network (the Internet). Layer 3 A similar main task, in our opinion, should be accomplished by projects of the Layer 3 level: ensuring interoperability and functioning of separate blockchain-ecosystems in a single global Internet of Value. The main characteristics that should be inherent to projects of the Layer 3 level are: - Should be based on off-chain technologies. - To be blockchain-agnostic, i.e. not be tied to a particular blockchain-ecosystem. - To provide the possibility of trustless multi-asset transactions, i.e. allow easy exchange of one cryptoasset for another in the process of making a payment. - To ensure payments’ atomicity. As for atomicity, we should return to the analogy using the conventional Internet. It transpires that the Transport layer is in charge of the analogue of atomicity: it’s rendered into a separate technological layer there. Whether a similar state of affairs will eventuate in the case of the Internet of Value will only be known with time. Meanwhile, this problem should be tackled one way or another. In general, precisely because of the characteristics discussed above, Layer 3 technologies are not restricted to ensuring interoperability and combining individual blockchain systems into a single global network. They can also connect traditional financial systems and physical assets, or other non-blockchain value carriers. Just as the Network layer in the conventional Internet abstracts from specific low-level data transfer technologies and ensures their global interaction, Layer 3 technologies in the Internet of Value can provide interoperability and global value transfer, regardless of where this value comes from or what its basic carrier is. Furthermore, Layer 3 technologies in the Internet of Value can become the basis for the functioning of the following practical solutions and services: - Payment systems - Decentralized cross-chain exchanges (Cross-chain DEX) - Cross-border Payments (“Crypto VISA”) - dAPP scaling - Solutions in the field of Internet of Things (IoT), and others. However, the most significant benefits will flow from the network effect of the Internet of Values. Each new service, and each new participant attracted by this service will increase the value of the entire Internet of Value network for all participants, including the various DLT projects. Layer 3 Solutions. Imagine if someone in the 1970s, exposed to only a few local area networks, were asked to describe a global Internet of the future — one that would allow half of the world’s population to instantly share any information. Imagine if they were asked to predict how this would affect the economic, professional, and social life of people. In the 1970s, it would be very difficult to predict what is now commonplace to us. Similarly, at our present stage of evolution, it is very difficult to imagine where a similar development — what we call the Internet of Value — will lead us. Conclusion It’s likely that, at some point in the future, the basic DLT technologies (Layer 1) will perform the main function of the carrier of value, a kind of custodianship of specialized value. Developers will focus primarily on the thorough implementation of these basic and natural functions. Meanwhile, the logistical functions for value transfer will be folded into the superstructures of the technological levels — Layer 2, 3, 4. Their task will be to solve a particular level of problems such as scalability, interoperability, and atomicity. Being separated into distinct levels of technology, they will be able to act beyond the limitations of lower-level technologies. This is especially true for interoperability. After all, a given blockchain-ecosystem, whatever it may be, is unlikely in itself to become what we could call the Internet of Value, just as WiFi could not become the internet. But all of them working together can. However, this will happen only in the event of the emergence of a Layer 3 technology which can ensure their interoperability. We in the team have been working on research in this area since 2015, and we are developing a solution that, we hope, can become part of the future Internet of Value.
