Ethereum Layer 2 Solutions

Along the way of the phenomena of blockchain technology development. Ethereum can be named a leader in decentralized applications (DApps) and smart contracts. For the moment Ethereum successfully manages to handle the growth of its user base. The services in demand are still limited. However, scalability becomes a very current issue as Ethereum’s user base keeps on growing. The demand for its services ever unfolds. Ethereum congestion and gas price spikes have been displeasing to the users. And led to inquiries about how effectively Ethereum can scale. Likewise, the Ethereum community has undertaken multiple innovation projects to address these challenges, intending to make the platform more scalable and flexible in performance. This article examines the technology being developed to hit big and the future of Ethereum Layer 2 Scaling Solutions.

Ethereum’s Scaling Challenges

Scalability being the crux of the matter, Ethereum struggles to meet the high demand for countless transactions compared to a decentralized network. Being based on a Proof of Work (PoW) consensus mechanism, the blockchain’s current network infrastructure is unable to deal with the growing transaction volume and network congestion. Thus whitening transaction confirmation times of the growing blockchain. Furthermore, the spikes in gas fees during rush hours have impacted so much on Ethereum users. So traditionally small transactions and forex trading using smart contracts become financially draining.

Layer 2 Solutions

Layer 2 scaling has seen the light of day as a promising solution that Ethereum can use to tackle scalability issues in a way that the applicable security and decentralization aspects are not compromised in any sense. These solutions are implemented on top of the Ethereum blockchain itself thus allowing quicker and cheaper processing. As transactions in a second chain either run off-chain or in a parallel to the main blockchain. Various Layer 2 solutions implement the Ethereum which all have unique features and some kind of benefits and disadvantages.

Optimistic Rollups

The most widely known (YYZ) of the Layer 2 scaling solutions is Optimistic Rollup (OR). This type of rollup is permissible as the transactions would otherwise have to be submitted to the blockchain for validation. And are aggregated into just one which is then verified using cryptographic proofs. Through the batching of several transactions into a single proof, Optimistic Rollups markedly decrease the number of calculations necessary for processing transactions on Ethereum and reduce their costs since the computational load and cost are distributed. Sequences like Optimism and Arbitrum have become popular for their applications of Optimistic Rollups, which intend to boost Ethereum’s scalability without shaving off its electricity and the state of centralization.

zk-Rollups

Besides Layer 2 solutions for Ethereum that use zk-Rollups based on zero-knowledge proofs to compress the data and exit them off-chain, another approach is L2 sidechains. zk-Rollups achieve increased privacy and scalability by way of the imitation function that is applied to identify a set of transactions without disclosing its contents to the community in general. By doing this the computational load of the Ethereum mainnet will be reduced. But the transaction lengths and privacy requirements will remain. As for the projects, such as ZKSync and Loopring, they are developing zk-Rollups to improve 2(two) scalability and users’ experience on Ethereum.

Plasma

Plasma is an L2 scaling solution that enables the creation of hierarchical blockchain structures with independent “daughter chains”. These daughter chains can individually process the transactions and then submit them to the Ethereum L1 network for final verification. Plasma chains execute transactions independently of each other, following the rules of their own consensus. They still provide a secure environment by accumulating unconfirmed transactions in this case. They is still needed to address its deficiency in real application and implementation. But projects such as OMG Network or Matter Labs agree that these challenges would be overcome by the emerging innovative approaches to Plasma technology.

State Channels

Channels controlled by state provide another path for scaling Ethereum along with enabling every party. To conduct off-chain interactions keeping the security and cleanliness of transactions intact. In the meanwhile, state channels allow the execution of several contracts off-chain. And at the end covering the final state on the Ethereum blockchain. It helps to relieve the congestion on the main chain network. It takes a load to the sidechain making the transactions speedy and highly cost effective which is beneficial for applications where high speed and low cost are the primary requirements. If a solution like Raiden Network or Connext will be developed by the projects mostly for the scalability. And the utility of the Ethereum Network it may be a game-changer in solving Ethereum’s scalability issue.

Sidechains

By using sidechains, a degree of independence from the main Ethereum network. We are able to employ parallel blockchains that operate independently of the main Ethernet. Such sidechains allow them to by pass mainnet bottlenecks in terms of transaction time/cost and gas for the user. Side chains are assumed to be of several types, private and public. Respectively, which leads to an overall level of centralization and security varying from one another. The layer-2 scalability projects like Polygon (previously Matic Network) and xDai Chain have brought interest back to the Ethereum ecosystem as many use these sidechains to increase the scalability of the network when they require using the Ethereum network for their projects.

Ethereum 2.0 (Eth2)

The most vitalistic of Ethereum’s serenity is Eth2, also called Eth2 or Serenity. Ethereum 2.0 is set out to solve the scalability, security, and sustainability issues that the platform faces with the help of a transition from a Proof of Work to a Proof of Stake (PoS) consensus mechanism and by implementing of shard chains. The Beacon Chain, which was launched in December 2020, is the foundation of Ethereum 2.0 (Eth2). It maintains the integrity of the POS consensus protocol. And may be upgraded at a later stage to include sharded blockchains. The division of the network by Shard chains will lead to more efficient Ethereum scalability capability by reducing the volume of each segment in order to facilitate parallel transaction processing and raise transaction rates.

The Merge

One of Ethereum’s most salient attributes is the move that should happen to become a reality in the coming days:. The merger of Ethereum 1.0 with Ethereum 2.0. The merge will represent the switch of the Ethereum’s existing PoW platform to the new PoS-oriented democratic mechanism. Where both networks will merge into one solid and cohesive system. The precinct is forecasted to cause the enlargement of the network’s capacity, the reduction of energy consumption. And the increase of the network security through establishing consensus rules that encourage legitimate validators.

Cross-Shard Communication

Communication across shards shapes the etherscale puzzle by allowing functions. Such as easy communication and interaction to happen among the different shard chains. The other work that has been incessant is to design protocols. And standards for effective multi-shard communication, something that will enable applications to operate across several shards with no compromise on performance or security. Ambiguities like Connext or Cosmos are making the jumps and their appearance are laying the foundation for a more coherent and scalable Ethereum ecosystem.

Other Innovations

Besides the Layer 2 solutions and Ethereum unlocks whose features are cutting edge. There are numerous other innovations the purpose of which is to make Ethereum scalable. Research are trying to find innovative methods to save the network’s efficiency, multipoint of a consensus algorithm and utilize all the resources available. Programs including Immutable-X and StarkWare are proving to be a revolutionary avenue for scaling Ethereum given the innovations. Introduced such as Validium and Validium Prime that are allowing new applications in the market to utilize decentralization and security offered by Ethereum.

Industry Collaboration

Partnership between the developers, researchers, and other economic agents has a paramount role in helping Ethereum to grow and survive in the long run. The solutions that address scalability cannot be achieved without joint effort, experience, resourcefulness, and cooperation, founded on overcoming technical barriers and developing new approaches. The Ethereum Foundation, ConsenSys, and other research sites, which are currently the main driving forces of fundraising, programming, and providing de-centralized knowledge for the Ethereum network development, are carrying out this exchange openly.

Conclusion

To sum up, there is the problem of Ethereum scaling which is multidimensional in nature and needs a persisting innovation. Layer 2 solutions, upgrade of Ethereum 2.0 and other research initiatives are principal elements that make progress in scalability issues. And new possibilities for decentralized applications and smart contracts, Scalability issue is still something that the community can be working on, yet the developers of Ethereum continue to work “hand-to-hand” with these drawbacks and produce a more scalable, efficient, and inclusive blockchain ecosystem for the future.
