Layer 2 Scaling Solutions| Revolutionizing Blockchain Scalability

Blockchain solutions development has changed various industries by providing decentralization of money, high levels of security, and irreversible record-keeping. Decentralization refers to the meaningful distribution of processing power and consensus throughout a network, while security refers to a blockchain protocol’s protections against bad actors and network assaults.

Blockchain Scalability

A blockchain in an ideal world would be capable of processing an infinite number of transactions per second TPS (Transactions per second). On the other hand, the Bitcoin main chain can only handle 3-7 TPS. Developers are working to broaden the scope of what a blockchain can achieve to meet these concerns. As a result, more transactions processing per second can happen along with reduced processing times.

What is Layer-2 Scaling Solution

Layer-2 refers to a supplemental framework or protocol built on top of an existing blockchain system. The fundamental goal of these protocols is to address the transaction speed and scale difficulties that plague the major cryptocurrency networks.

Workings of Layer-2 Solutions

Layers 1 and 2 are linked, and a summary of Layer-2 transactions is uploaded to Layer 1 at regular intervals for archival purposes. Layer-2 networks must consider how transactions are validated before they are "cast in concrete" on the main chain.

Types of Layer-2 solutions

Rollups

Layer-2 scaling options, known as rollups, offload transaction processing off the main Ethereum network while still publishing transaction data to layer 1. Because transaction data is stored on layer 1, rollups are subject to the same layer 1 security standards as transactions. For users, this is the differentiating feature of rollups.

Rollups are beneficial because they reduce transaction costs, increase transaction throughput, and increase participation. Rollups come in two sorts, each with its own set of security features:

1. Optimistic Rollups

2. Zero-knowledge rollups

Sidechains

Sidechains combine Layer 1 and Layer 2 scaling algorithms. A sidechain is a blockchain of a cryptocurrency’s main chain, such as Bitcoin.

Plasma Chains

Solutions for Plasma Layer-2 Ethereum uses child or subsidiary blockchains to aid in the verification of the parent chain. Like sidechains, plasma chains feature a consensus process and generate transaction blocks.

State Channels

A channel creation happens between two parties after crypto placement in an Ethereum smart contract. After the execution of payments, Layer-2 is where signed ticket creation happens. After ticket finalization on Layer 1, it gets signed. If state channels have been opened earlier, they can be bidirectional and handle a second party.

Conclusion

As a result, L2 scaling solutions will play a critical role in supporting a multichain future. Also, it will put the onus on developers to guarantee sustainable growth without compromising the core precepts of blockchains: security, decentralization, and scalability.
