How Totally different Sorts of Layer 2 Options are Redefining Blockchain’s Future

Learn Time: 5 minutes

Ethereum stands out amongst good contract blockchains, largely as a result of substantial affect of Layer 2 options on its rise. These options, resembling Optimism and Arbitrum, boast a bigger Complete Worth Locked (TVL) on Ethereum than main Layer 1 blockchains like Solana.

Layer 2 options are designed to reinforce Ethereum’s capabilities, aiming to make the community sooner, extra scalable, and cheaper for customers when making transactions.

Now that we’ve touched on the significance of Layer 2, let’s delve into the article to discover the broader Layer 2 ecosystem and the various kinds of Layer 2 options out there.

Diving into the world of Layer 2:

Why does it matter?

Blockchain is way praised for its fascinating qualities of Decentralization, Safety and Scalability. However attempting to have all three without delay? Tremendous onerous. Compromising on any of it means slower transactions, increased prices, and gradual processing instances—layer 2 options step in to deal with these challenges utilizing an modern strategy. 

How does Layer 2 resolve the blockchain trilemma?

Layer 2 options work their magic by shifting transactions to totally different Layers. This fashion, they deal with extra transactions approach sooner and cost-effectively. Consider it like bundling a bunch of off-chain transactions into one large on-chain transaction. This makes charges a lot decrease, making Ethereum user-friendly for tons extra folks.

That’s why large gamers like Arbitrum and Polygon are all in for making crypto transactions simpler and cheaper and opening the door to extra issues we are able to do on blockchains.

How have Layer 2 options improved blockchain utilization?

The adoption of Layer 2 scaling options is clear by way of the growing variety of each day energetic addresses, surpassing a number of Layer 1 blockchain networks. Let’s discover the affect these options have had.

  • Arbitrum leads the way in which in creating Layer 2 options, boasting a thriving ecosystem of 331 decentralized purposes.
  • Complete Worth Locked (TVL) showcases consumer belief, emphasizing a robust desire for Layer 2 options. Each Arbitrum and Optimism exceed the TVL of competing Layer 1 chains like Solana and Avalanche, reflecting consumer confidence.
  • Within the realm of notable Layer 2 tasks, Optimism and Arbitrum stand out with practically $1 billion market caps and efficiently launched tokens. 
  • Starknet reveals distinctive developer engagement, whereas zkSync leads in each day addresses and complete transactions among the many listed Layer 2 options.
  • Optimism’s progress, attributed partly to its Optimism Superchain imaginative and prescient and BASE’s involvement, has made it the biggest Layer 2 by market cap. (Extra on this Superchain beneath).

Now that we’ve lined the prominence of Layer 2 options, let’s delve into the varied sorts of Layer 2.

What are the various kinds of Layer 2s?

Layer 2 options will be broadly categorized as, 

  • Rollups
  • State Channels
  • Plasma
  • Aspect Chains 


Layer 2 rollups are scaling options working off the Ethereum blockchain however document transaction knowledge on the primary chain (Layer 1), securing transactions with Layer 1’s safety measures.

Here’s a listing of some properties of rollups,

  • By executing transactions, it reduces fuel charges.
  • Transaction knowledge resides on Layer 1, thereby guaranteeing safety.
  • A rollup good contract on Layer 1 oversees and enforces transaction execution on Layer 2 utilizing saved Layer 1 knowledge.
  • Customers stake a bond within the rollup good contract, incentivizing correct transaction verification.

There are two sorts of Rollups:

  1. Optimistic Rollups: Function parallel to Ethereum’s mainnet on Layer 2 and don’t compute transactions by default. After finishing transactions, it submits new states to the Ethereum mainnet, decreasing fuel charges.

Benefits: Low fuel charges, elevated throughput, good contract capabilities, Ethereum Mainnet’s safety.

Purposes: Arbitrum, Boba, Cartesi, Gas Community, Optimism

  1. Zero-Information Rollups (ZK Rollups): Bundles quite a few transactions off Ethereum’s foremost chain, creating cryptographic proofs referred to as SNARKs (succinct, non-interactive argument of data). Hold transaction knowledge on Layer 2 and edit it solely with validity proof, decreasing knowledge inclusion and transaction prices.

Benefits: Close to immediate transfers, enhanced safety, decentralization.

Purposes: Aztec 2.0, Immutable X, Loopring, Matter Labs zkSync, Polygon Hermez, Starkware, zkTube

State Channels

State channels are a method that allows individuals to execute quite a few transactions off the primary blockchain (like Ethereum) swiftly and with out incurring the same old charges and time delays. These transactions happen privately between concerned events and are solely settled on the primary blockchain after finishing all interactions off-chain.

Purposes: Raiden Community is a venture devoted to refining and implementing state channel know-how.


Plasma chains are unbiased blockchains linked to the Ethereum foremost chain by way of anchoring. They leverage fraud proofs, much like optimistic rollups, to resolve disputes or discrepancies that may come up throughout the chain.

Purposes: OMG Community implements Layer-2 Plasma structure to facilitate quick and safe transactions. 

Aspect Chains

Sidechains are unbiased blockchains that run alongside the primary blockchain, working parallel to it. They’re linked to the primary blockchain, permitting property to maneuver between the mainchain and the sidechain effectively.

These sidechains alleviate the mainchain’s load by dealing with transactions and good contract executions on their very own. Doing this enhances scalability, making transactions faster and less expensive.

Sidechains supply flexibility by enabling custom-made consensus mechanisms and rule units. This adaptability permits for specialised use instances tailor-made to particular wants, as they are often designed in a different way from the primary blockchain.

Purposes: Polygon PoS 

Closing Ideas

Whereas Layer 2 options supply scalability and transaction effectivity, safety stays a big concern regardless of efforts to take care of the primary chain’s safety. The susceptibility to assaults is tied carefully to every community’s design and execution, making strong safety measures essential.

Furthermore, the complexity launched by various Layer 2 networks poses new challenges and vulnerabilities. This complexity calls for a meticulous strategy to safety to mitigate potential dangers.
