Types Of Layer 2 Blockchain Protocols
Layer 2 solutions are a way to increase the speed and scalability of blockchain networks, and the protocols used in these solutions aim to make blockchain technology more user-friendly and cost-effective. In this post, we will be discussing the four types of layer 2 blockchain protocols.
Payment Channel Networks Such As Lightning Network And Raiden Network
Payment channel networks or pcns are designed to reduce the cost and processing time of blockchain transactions. These protocols enable the creation of off-chain payment channels between two parties, allowing for multiple transactions to take place without the need for every block to be broadcasted and validated on the main blockchain.
Here are some key points about payment channel networks:
- The lightning network is the most widely used pcn for bitcoin blockchain, while raiden network is ethereum’s equivalent.
- In pcns, users can transact with each other without relying on third-party intermediaries or mining fees.
- These protocols can significantly increase the speed of transaction processing on the blockchain.
Sidechains Such As Liquid Network And Plasma
The second type of layer 2 blockchain protocol is the sidechain. Sidechains allow for the transfer of assets from one blockchain platform to another, which reduces the load on the main blockchain and increases its scalability while maintaining full security.
Here are some important points about sidechains:
- The liquid network is a popular sidechain for bitcoin, while plasma is ethereum’s sidechain protocol.
- These protocols rely on pegging, which allows assets to be transferred securely between two chains.
- They are useful when there is a need for fast and cheap transactions with reduced load on the main blockchain.
State Channels Such As Connext Network And Celer Network
State channels are similar to payment channel networks, but they are designed to handle smart contracts as well as asset transfers. In other words, state channels allow for more complex transactions to take place off-chain while still retaining the security and reliability of the blockchain.
Here are some points to remember about state channels:
- Connext network and celer network are popular state channel protocols for ethereum.
- In state channels, smart contracts can be executed off-chain, which reduces computational requirements on the blockchain.
- State channels provide faster transaction times and lower costs for complex and frequent transactions.
Rollups Such As Zk-Rollups And Optimistic Rollups
Rollup protocols are designed to increase scalability by bundling multiple transaction inputs into a single transaction output, reducing the load on the blockchain. They come in two types: zk-rollups and optimistic rollups, and each uses a different approach to bundling transactions.
Here are some points to remember about rollups:
- Zk-rollups use zero-knowledge proofs to bundle transactions securely while preserving privacy.
- Optimistic rollups do not use zero-knowledge proofs, but instead rely on optimistic assumptions that most transactions are valid.
- Rollup protocols are expected to significantly increase the throughput of blockchain transactions.
Layer 2 blockchain protocols are innovative solutions that increase the speed and scalability of blockchain networks. The protocols used in these solutions allow for faster and cheaper transactions, reduced load on the main blockchain, and improved scalability. These types of protocols are essential for the mainstream adoption of blockchain technology.
How Layer 2 Blockchain Addresses The Scalability Issue

Solutions Offered By Layer 2 Blockchain Technology To Address Scalability Issue
- Layer 2 blockchain technology is built on top of layer 1, offering a viable solution to scalability issues.
- With layer 2, transactions are processed more cheaply and quickly by allowing activities off-chained from the main blockchain, using channels for private transactions.
- Layer 2 blockchains reduce the number of interactions carried out on layer 1, thereby offering a more efficient and scalable solution.
- Off-chain scaling solutions enable a higher throughput, faster transaction finality, and lower fees due to reduced congestion in the main chain.
Examples Of How Layer 2 Blockchain Can Significantly Increase Transaction Speed And Volume
- Bitcoin’s lightning network operates as a layer 2 blockchain solution and enables faster and cheaper payments by bundling multiple transactions into one blockchain channel.
