A zero layer or Layer0 blockchain is a type of protocol that enables communication and interoperability between different Layer one (Layer1), two (Layer2) and three (Layer3) blockchains.
This is possible because a Layer0 blockchain is in charge of validating the data that is transferred between the different networks, without the need to depend on smart contracts or other external solutions. In this way, a Layer0 can improve the scalability and efficiency of decentralized applications that are built on top of other blockchains.
An example of a zero layer blockchain is Polka dots (DOT). This Layer0 capability in Polkadot is possible thanks to the use of a technology generated by this project that is known as Substrate. Thanks to this development, Polkadot is capable of generating parachains (parallel blockchains) capable of connecting different layer one blockchains, such as Ethereum, Bitcoin or BNB Smart Chain. In this case, each parachain has its own logic, token and consensus mechanism, but you can benefit from the security and performance of Polkadot's mainnet.
Another Layer0 blockchain is Cosmos (ATOM), which uses hubs to connect different layer one blockchains, such as Ethereum, Binance Chain or Kava. Each hub has its own token and consensus mechanism, but can facilitate the exchange and transfer of value between the various networks. The same can be seen replicated in Avalanche or in Horizen, which are also other examples of what a Zero Layer blockchain is.
In this way, Layer0 blockchains become an important innovation in the world of cryptocurrencies, since they allow the creation of more diverse ecosystems, flexible and collaborative. Above all, because by facilitating interoperability between the different blockchains, Layer0 can drive the development and adoption of decentralized applications in different sectors and use cases.
How does Layer Zero Blockchain work?
The operation of a zero-layer or Layer0 blockchain is based on the creation of a blockchain development framework, which allows the generation of a peer-to-peer (P2P) communications network on which an initial blockchain is based that can later be be used to generate bridges or interoperability bridges with other blockchains (eg Bitcoin) or for the creation of new blockchains based on said development framework (eg Polkadot parachains that use Substrate for this task).
In this case, The generation of the P2P network is in charge of communicating all the processes between the different parties. In addition, this secondary network is responsible for processing transactions and validating them. Once a transaction is validated, it is added to the underlying blockchain.
The Zero Layer Blockchain uses a Proof of Stake (PoS) consensus mechanism, which is more efficient than the Proof of Work (PoW) mechanism used by Bitcoin and Ethereum. PoS allows users to validate transactions by staking their tokens. The more tokens a user stakes, the more likely they are to be selected to validate transactions. The Zero Layer Blockchain also uses the fragmentation (sharding), a technique that allows you to divide the network into smaller, more manageable parts. Thus each shard can process transactions independently, which means that the network can handle a much larger number of transactions.
For example, in the following image we can see how Polkadot serves as Layer0 to generate a new network with a very clear objective: sustain Acala's DeFi services. Acala divides all its needs and develops them as needed to respond to the needs of its users. But at the same time, the use of Polkadot and its Layer0 capability allows the project to have advanced services to manage decentralized applications that revolve around Acala. Thus, Acala can generate tools to interconnect with other ecosystems, such as the case of Acala's EVM to interoperate with networks such as Ethereum and compatible ones.
Advantages of the Zero Layer Blockchain
The Layer Zero (Layer0) Blockchain offers several advantages over existing blockchain technology. These are some of the main advantages:
Scalability
The most significant advantage of the Zero Layer Blockchain is its Scalability. By creating a secondary network that handles transaction processing, the underlying blockchain can focus on security and consensus. This approach allows the network handle a much larger number of transactions, which is essential for many applications.
Take for example Polkadot and its parachais. Polkadot with Substrate offers Layer0 or Layer Zero capability that we can explore through its parachains. Each parachain on Polkadot is capable of generating its own network of nodes, its own consensus rules, its own unique ecosystem and capabilities, which uniquely extends the system.
But not only that, parachains isolate the execution of operations from the rest of the elements of the network and with this provide a greater capacity to scale, which, together with Proof of Stake systems and high-speed BFT systems, have a positive impact on overall scalability. of the network.
Speed
The Zero Layer Blockchain can process transactions much faster than existing blockchain technology. This is because the secondary network is optimized for transaction processing. By using sharding and a PoS consensus mechanism, the network can validate transactions quickly and very efficiently.
Security
The Zero Layer Blockchain maintains the same level of security as the underlying blockchain. This is because the secondary network is built on top of the existing blockchain and uses the same security protocols.
Cost
Finally, Layer Zero blockchains are more cost effective than existing blockchain technology. This is because the secondary network is optimized for transaction processing, which means that the network can handle a higher number of transactions without the need for expensive hardware. Not only that, being networks with great speed and scalability, network fees tend to be much lower in cost compared to other blockchain networks.
Importance and necessity of zero layer blockchains
All the above advantages make it very clear to us the importance and the need to build this type of blockchain technology. On the one hand, developers understand that blockchain technology faces a significant challenge in terms of scalability, speed, and cost of operation/use. Addressing this problem without destroying the decentralization of the blockchain is not an easy challenge to overcome, in fact, this problem is known as the “Scalability Trilemma” or “Blockchain Trilemma”. However, zero-layer blockchains can open the doors to solve this problem permanently.
For example, Bitcoin can only process seven transactions per second, and Ethereum can only process fifteen transactions per second. This limitation makes it difficult to use Blockchain technology for applications that require high performance, such as financial transactions, supply chain management, and IoT applications.
However, networks such as Polkadot or Cosmos can easily process 1000 transactions per second, and this capacity is extended with the use of parachains/hubs, taking this operational load to their own networks that process said transactions and in the end only record a summary of all the operations carried out in the main network. Thanks to this, zero-layer blockchains can perfectly cope with large numbers of users, which makes it possible to generate applications of massive reach, without sacrificing the decentralization of the network.
Use cases of Layer Zero Blockchain
The Zero Layer Blockchain has several use cases, some of which are:
Financial transactions
The financial sector is one of the main beneficiaries of Blockchain technology. However, existing blockchain technology is not suitable for high-throughput financial transactions. The Zero Layer Blockchain is designed to manage high-performance financial transactions, which makes it an ideal solution for the financial sector.
Supply chain management
The zero-layer blockchain can also be used to manage the supply chain, since applications with high performance and very high scalability are needed.
IoT applications
The Internet of Things (IoT) is another area where Blockchain technology can be used. However, existing blockchain technology is not suitable for IoT applications that require high performance. The Zero Layer Blockchain can handle high-performance IoT applications, making it an ideal solution for the industry.
