Blockchain technology, which combines ideas from game theory and other contemporary technologies, has many potential applications, including the creation of digital currencies. A blockchain lowers costs, boosts efficiency, and eliminates the need for middlemen by providing transparency and security. Through the use of technology, trust is developed between people or groups that would not otherwise be motivated to do so. This makes it possible for users on blockchain networks to exchange data and values securely.
Since there is no central authority, blockchains need to be extremely secure. In order to handle increasing user numbers, transaction volumes, and other data, they must also be highly scalable. This need for scalability while preserving the highest level of security led to the development of blockchain layers, or blockchains on top of blockchains.
What is the scalability of a blockchain?
The increasing use of digital currencies in daily life has made blockchain layers all but essential as they improve network security, revolutionise recordkeeping, and more.
Consider Bitcoin.
The Visa network's electronic payment network can process over 20,000 transactions per second, whereas Bitcoin's primary chain can only handle seven. The disparity is astounding. For this reason, there are currently many layer two blockchain technologies in use. These systems use smart contracts to automate transactions.
What is the significance of blockchain scalability?
Since a blockchain cannot simultaneously optimise for every desired feature, trade-offs must be made. Due to the increased transaction costs caused by the increased demand, some people are no longer able to use the blockchain.
Blockchains like Ethereum and Bitcoin don't have much room to grow these days. To overcome the blockchain trilemma, a global community of IT firms, startups, and researchers is frantically developing layer one and layer two solutions. Blockchain systems are designed to be scalable, secure, and fast. Additionally, they back new products and technologies that could make existing blockchain networks more scalable. By adding another layer to the current blockchain layer, Bitcoin aims to solve the issue.
Blockchain developers are working to broaden the scope of blockchain efficiency as Bitcoin gains traction in the business world. We can reduce processing times and increase TPS (transactions per second) by creating blockchain layers and improving scalability through what are now known as "layer two" solutions.
What are the layers of a blockchain?
Understanding the answers to questions like "What are blockchain layers?" is crucial when studying blockchain technology.
Because there is no central authority overseeing all transactions on a blockchain, data is securely stored on a distributed ledger that is open to all users for access and verification. Such a distributed ledger system adheres to a preset protocol that requires that multiple computers (or nodes) in the network reach a "consensus" in order to validate transactional data. Every node is constantly adding, reviewing, and editing new entries.
Let's get right to the point: what are blockchain layers? Blockchains use a layered architecture to provide this special method of transaction authentication. Each of the five phases of play has a distinct set of duties. Below is an explanation of the blockchain's layers.
Layer 1 vs Layer 2 Blockchains Networks Explained
An Overview of Layers 1 and 2
The throughput, or processing speed, of any digital currency blockchain network can be increased with Layer 1 and Layer 2 blockchain scaling solutions. To assist in processing more transactions, they may consist of additional network solutions or protocol updates.
Updates like altering block sizes, consensus procedures, or sharding—the division of a database into several sections—are included in Layer 1. Layer 2 consists of off-chain transaction processing (also called state channels), parallel blockchains (also called side chains), and rollups (bundling transactions).
Important Takeaways
- Solutions for Layer 1 and Layer 2 blockchain scaling aid in raising a blockchain network's overall throughput, which is another term for processing speed.
- Updates to primary blockchains, such as those pertaining to database partitioning, consensus methods, and block sizes, are included in Layer 1 scaling.
- Transaction bundling, parallel processing, and off-chain transaction handling are examples of Layer 2 scaling.
- A blockchain's security may be jeopardised by Layer 1 and Layer 2 scaling.
The Significance of Layer 1 and Layer 2 Scaling Solutions
With consensus protocols that confirm the transactions' accuracy, a blockchain is a decentralised network of nodes that handles digital currency transactions autonomously. After that, the transactions are sequentially recorded, creating an unchangeable chain of data blocks.
Regretfully, as a blockchain gains popularity Bitcoin is one example it requires more processing power to manage the increasing volume of transactions. Blockchain protocols for digital currencies may also restrict the volume of transactions that can be handled, causing a network bottleneck.
Popular blockchain networks have become extremely slow as a result, occasionally processing transactions in as long as ten minutes or longer. Scaling activities have been created to address this problem and offer a more effective way to handle a significantly higher volume of transactions.
Every network can be scaled in a variety of ways, and numerous scaling solutions have been created for different well-known blockchains. Through a code update, these solutions assist in improving the base-layer network itself or offloading the transaction processing power onto other networks.
Comparing Layer 1 and Layer 2 Blockchains
The foundational design of a decentralised digital currency network is a Layer 1 blockchain. Ethereum, Cardano, and Bitcoin are a few instances of Layer 1 blockchains. These blockchains use a shared consensus mechanism, like proof of stake (PoS) or evidence of work (PoW), to manage transaction processing and network security.
An additional blockchain or collection of protocols that are layered "on top" of a Layer 1 solution is referred to as a Layer 2 blockchain. Although Layer 2 protocols are more adaptable in their capacity to scale transaction processing and network throughput overall, they still rely on the Layer 1 blockchain for network and security infrastructure. Bitcoin's Lightning Network and Polygon, which sits on top of Ethereum, are two examples. In August 2023, Coinbase's Ethereum Layer 2 network, Base, went live.
Types of Blockchain Scaling Solutions for Layer 1
Layer 1 blockchains can be scaled in a number of ways, such as:
A larger block size
The code of some Layer 1 digital currency blockchains has been modified to increase the block size, which enables more transactions to be verified simultaneously and increases the network's overall capacity. The Bitcoin Cash (BCH) network is one example of this; it increased the block size from 1 MB to 8 MB and then to 32 MB, which should enable it to process over 100 transactions per second as opposed to Bitcoin's seven transactions per second.
Revised Consensus Process
A blockchain's consensus process verifies transactions to guarantee the network's accuracy and security. For instance, the proof-of-work (PoW) consensus used by Bitcoin necessitates a significant amount of processing power in order to solve a puzzle and record the subsequent block in the blockchain. After the puzzle is solved, the blockchain verifies block hashes to validate transactions in the blocks.
In order to process transactions, node operators must lock up a sizable Ethereum (ETH) deposit. Ethereum also used proof-of-work (PoW) at first but has since switched to proof-of-stake (PoS) consensus.
Sharding
Database partitioning, which divides a blockchain database into smaller sections so that transactions can be handled concurrently, is comparable to sharding. This boosts a Layer 1 blockchain network's overall capacity.
Types of Blockchain Scaling Solutions for Layer 2
Additionally, there are various kinds of Layer 2 blockchain scaling solutions, such as:
Roll-ups
The number of transactions that can be processed simultaneously can be greatly increased by "rolling up" bundles of transactions into a single transaction rather than processing them separately. The transactions are contracted out to be bundled, recorded off-chain, and then processed as a single unit on the main chain.
Five Side Chains
Side chains are independent blockchain networks with their own set of validators that allow transactions to be processed in parallel. This vastly increases the transaction-processing power of a blockchain, but you must trust the integrity of the sidechain network and the bridge network that connects it to the main blockchain.
State Channels
State channels are similar to a side chain, as transactions are recorded off-chain, but these transactions are recorded in bulk off-chain, and then the state of the channel is set at complete. The transactions are then recorded in bulk on the main blockchain network by broadcasting a completed “state” to the main network. This is how Bitcoin’s Lightning Network is set up.
Hazards of Blockchain Scaling Solutions at Layers 1 and 2
There are some risks associated with using a scaling solution, even though scaling a blockchain is a fantastic way to enhance transaction handling and boost overall adoption:
- Forks in blockchains: Blockchains are collections of data blocks, or files, that contain a record of every transaction in chronological order. Supporters of the blockchain may become divided if a fork of the blockchain is necessary to update it to scale. The scaling update can occur when the code is forked, but this causes two networks (like Bitcoin and Bitcoin Cash) to operate concurrently. Users may become perplexed, and the value of digital currencies as a whole may decline.
- More difficult to confirm: Certain scaling solutions transfer transactions to an off-chain network, preventing public verification. Because of this lack of transparency, a blockchain could be vulnerable to malicious actors who want to alter transaction data.
Layer 1 and Layer 2: What Are They?
Any solutions that manage transactions are referred to as off-chain Layer 2 blockchains by the digital currency community, while the primary blockchain is known as Layer 1. Although a blockchain actually consists of multiple layers, only Layers 1 and 2 are used to describe scaling solutions for a blockchain. These layers include hardware, data, network, consensus, and application.
Layer 2 scaling: what is it?
A blockchain called Layer 2 was created to finish tasks for the main blockchain more quickly. The blockchain is adjusted for increased throughput by Layer 2 scaling.
What is an example of a Layer 1 scaling solution?
An example of a Layer 1 scaling solution is Ethereum's transition to proof-of-stake, which reduced the network's processing demands and enabled a planned future of hundreds of thousands of transactions per second.
