Overthrowing the Scale with Blockchain Technology
Blockchain technology has come a long way since its launch with Bitcoin. Technology adoption has been increasing over time; however, before blockchain technology is central, it must have the scaling capability necessary for mainstream use as one of the issues that form part of the blockchain triad of scalability, interop, ability, and efficiency, a number of blockchain projects in the market are looking for ways to increase the scalability of blockchain technology. In this article, we will take a look at the different layers that make up blockchain technology, the two types of blockchain scalability, and a blockchain ecosystem that could be a solution to help scale all connected blockchains.
Different Layers of Blockchain Technology
Just as a blockchain consists of several nodes, it also cons various layers. Each layer fulfills a specific role in the blockchain net, works, and when combined with other layers, makes it possible to have a distributed system.
This is the layer where all the applications that use the blockchain for their specific use-cases are. These use cases benefit from the decentralization made possible by other layers of the blockchain.
This layer facilitates the intelligent contracts of the network and is responsible for creating workflows and how the user interacts with the system.
This layer takes care of the smart contract itself. Smart contracts must be coded correctly as there can be financial repercussions for poorly designed intelligent contracts. Therefore, developers must pass multiple audits to identify potential weaknesses in the code before deployment.
All the necessary components to protect the blockchain reside in this layer. This layer consists of features such as mining consensus and all its associated subsystems.
Data is stored at this layer and can be kept both off-chain, in the database, and on-chain.
The network layer is the foundation of every blockchain. This layer is the peer network that makes up the blockchain network. Continuous communication of the current state of the blockchain is handled by each of the peers who broadcast the state to other peers in the network. Peers also handle communication regarding the security of the blockchain and the data transmitted within the network.
Types of Blockchain Scaling
There have been many approaches to enable the scalability of blockchain technology. Some of these approaches focused on making improvements at one or more of the layers covered above. These scaling approaches can be divided into two categories: on-chain scaling and off-chain scaling. These categories are known as tier 1 (on-chain) and tier 2 scaling (off-chain).
On-chain or layer 1, scaling and improvements are made to the blockchain. The primary purpose of these on-chain improvements is to change the network's consensus rules to increase the network's overall speed and throughput. An example of Tier 1 scaling is increasing transaction block sizes so that transactions can be processed much faster as more transactions can be processed and stored simultaneously.
Off-chain, or layer 2 scaling, refers to methods of scaling a blockchain without making any changes to it. This is achieved by implementing solutions that are augmented in nature and run on top of the blockchain to expand their capabilities. Tier 2 scaling solutions aim to remove the burden of high transaction volumes from the primary blockchain through off-chain processing. Once processed off-chain, transactions are sent to the blockchain for finality. An example of off-chain scaling is nested blockchains. These are smaller blockchains built on the primary blockchain so that the transaction processing is more distributed across the network. These smaller blockchains process small chunks of the blockchain's transactions and then send them to the primary blockchain for precision.
Several blockchain projects in the market are trying to solve the blockchain's scalability problem. These solutions enhance or replace one or more of the layers that make up a blockchain network, either on-chain, layer 1, scaling solutions, or off-chain, layer 2, scaling solutions.
A Project That Solves Blockchain Scalability
Posschain is a blockchain ecosystem that will enable the scalability of any blockchain connected to the ecosystem. This is achieved by combining both on-chain and off-chain scalability solutions and an AI-based Proof of Stake consensus model with a secure and scalable parallel protocol for distributed ledgers. It is a hybrid solution for distributed ledgers that combines similar scalable protocol, sharding, sidechains, and off-chain processing. Posschain can achieve accelerated block release times by combining these protocols and blockchain technologies.
