Good Ethereum scaling solutions help provide web3 developers and users with lower gas fees and faster transactions, while also keeping transactions secure. Ethereum scaling solutions are platforms specifically designed to improve transaction execution on the Ethereum network. Ethereum scaling solutions like layer 2 rollups and sidechains are protocols that use different mechanisms to increase network throughput.


The platform also offers support for pallets on Ethereum Virtual Machine for ensuring seamless compatibility with decentralized applications developed over Ethereum. Best Ethereum layer 2 solutions is the support for sidechain aggregation of transactions, also referred to as the rollup technology. Most important of all, the different notable entries in the list of partners of Arbitrum include Chainlink, Graph Protocol, OKEx, and many others. Both optimistic and zero-knowledge rollups bundle (or ’roll up’) hundreds of transactions into a single transaction on layer 1. Rollup transactions get executed outside of layer 1 but transaction data gets posted to layer 1.

The difference lies in the level of decentralization and privacy that Bitcoin and other blockchains aim to provide. It takes a good deal of time and processing power to replace a simple centralized system. Each transaction must be accepted, mined, distributed, and validated by a global network of nodes. Zero-knowledge rollups (ZK-Rollups) consolidate transactions that have been taken off the main blockchain and generate a cryptographic proof known as a SNARK (Succinct Non-Interactive Argument of Knowledge). This proof, also called a validity proof, is the only record required on the main blockchain; hence, reducing the gas fee that users would have incurred from processing the entire data.

The two main methods of transferring value between L2s and the Ethereum mainnet are Optimistic Rollups and zk-Rollups. Within the payment channel, the IOUs will be accepted as money because both parties know that they have enough assets locked away for their IOUs to be redeemed in full when necessary. Layer 2 solutions like Polygon, Arbitrum, Loopring and Optimism currently exist on Ethereum to mitigate some of these scalability challenges. From user-centric mobile apps to full-blown cross-platform enterprise ecosystems — we’ll bring your concept to life, exactly as you think it should look and work.

The different Ethereum layer 2 solutions introduced here have prolific potential for disrupting the blockchain landscape in a positive way. Layer 2 solutions are basically the next big thing in ensuring the resourceful utilization of blockchain networks. On the other hand, it is also important to note that many Ethereum layer 2 solutions are in the development or testing stages. So, it may take some time before we see full-fledged layer 2 solutions dominating the Ethereum landscape. Ethereum layer 2 scaling solutions could serve different functions such as off-chain computation and scalability of payments.

  • Data aggregators will compute merkle roots to achieve increased transaction speeds.
  • This technique has a series of smart contracts running on top of a root blockchain.
  • The compiler helps in the compilation of an assortment of Solidity smart contracts into an executable file compatible with running on AVM or the Arbitrary Virtual Machine.
  • While these are in the roadmap, further scaling through layer 2 networks is still necessary.
  • Beyond improving scalability, rollups offer levels of security similar to Ethereum itself because transactions in rollups are anchored to the L1 chain, which guarantees transaction finality.

https://www.beaxy.com/’s Lightning Network is an example of a payment channel layer 2 solution, enabling very low-fee micro-transactions. So for example, if I want to make five transactions to my friend Jane, each time sending her 1 BTC, the main blockchain will only record a single transaction at the end validating that Jane now has 5 BTC. The two largest blockchain networks, Bitcoin and Ethereum, currently have different layer 2 solutions built on top of their main chains. Read on to learn about layer 2 scaling solutions and how they are helping Ethereum retain its market-leading position as a smart contract protocol. As stated earlier, the Ethereum blockchain suffers from slow transaction speed and high gas costs, especially during network spikes, mostly due to its initial design that favors decentralization and security over scalability.

Some layer 1 blockchains have higher throughput and lower transaction fees than Ethereum. These alternative layer 1s have had to sacrifice on security or decentralization in order to achieve higher transactions per second and lower transaction fees. The Ethereum community has taken a strong stance that it would not throw out decentralization or security in order to scale.

L2BEAT is an analytics and research website about Ethereum layer two scaling. We provide a comparison of the various Ethereum L2 systems available today. Although the Lightning Network was originally designed to scale Bitcoin, cryptocurrencies such as Litecoin and Dogecoin have also integrated the solution. Projects offering sidechain implementations include POA Network and xDai chain. Compatibility is achieved via a two-way bridge to Ethereum, though its security is not directly inherited and is the responsibility of the sidechain. The catalysts and technology coming to Ethereum form a compelling case to be positive about the growth of Ethereum’s ecosystem and increasing user adoption.

The Layer 2 Landscape Is Evolving, and Adoption Is Rising:

As a result, ZK-proofs offer faster finality times while remaining ADA secure and decentralized since the data needed to recover the state is stored on Ethereum layer 1. However, some ZK-rollups do not have EVM support, and validity proofs are intensive to compute, making them unsuitable for dApps with little on-chain activity. L2 solutions can help solve the scalability trilemma as they’re built on L1, so they can secure off-chain interactions by leveraging the security of L1. This helps to ensure there are no security trade-offs, while helping to provide more block space for transactions to be processed—helping scale the network and reduce transaction fees.. Ethereum’s Plasma layer 2 solution uses child or secondary blockchains that will assist the main chain in verification. Plasma chains are similar to smart contracts or parachains from Polkadot.

Ethereum 2.0 is the upgrade expected to significantly boost the network’s scaling performance, but it isn’t due until 2023. EthBridge is basically a decentralized application, which is deployed on the Ethereum main network. It serves as a connection between the Ethereum main network and Arbitrum. Best Ethereum layer 2 solutions that have been successful in resolving many critical issues.

Both offer different approaches for the Ethereum mainnet to confirm the true state of operations on the execution layers (i.e., account balances and total values in each L2) without the need to validate every single transaction. Like a payments channel, fees are only incurred to open and close the channel, and any transactions that occur between users within the channel are essentially instantaneous and free. They are also much cheaper because users only need to pay a fee to the L1 when locking their funds in a smart contract to open the channel, and when submitting the final balances to the L1 in order to close the channel. By contrast, layer 2 networks exist primarily to scale a single layer 1 network.

The main problem with the growing blockchain and crypto space is that there is a scarcity in processing transactions. What gives it a solid back up is Ethereum’s emphasis on decentralization and security. The reason may trigger a question of what the problem of scalability affects. In short, it affects the overall network throughput and as a result affects the scaling ability of decentralized applications . It is basically a sidechain based on Ethereum, which supports users in processing transactions at faster speeds and reduced costs.

Is Avax a layer 2 solution?

Avalanche is a layer 1 smart contract based blockchain that tries to address the most challenging issues in the space such as transaction fees and scalability.

To prove the validity of transactions, child chains submit cryptographic proofs to the root chain. Sidechains designed specifically for Ethereum have Ethereum Virtual Machine compatibility and can support smart contracts. This means you can deploy projects on sidechains and leverage their scalability improvements for dApps. ZK-rollups are more secure since they generate validity proofs, however, this makes them slower than optimistic rollups.

The ethereum layer 2 scaling solutions blockchain can only process a maximum of 13 – 15 transactions per second. And as on-chain activities increase, the network becomes congested, drastically reducing transaction speed. This, in turn, affects ETH gas prices as users aim to outbid each other for confirmation of transactions. And, therefore, a poor and expensive long-term choice for decentralized applications. Layer 2 scaling solutions are protocols built on top of an existing blockchain to achieve higher throughput and transaction speeds without compromising decentralization or security.

Ethereum’s emphasis on decentralization and security means that transactions are processed slowly. This affects network throughput and impacts the ability of decentralized applications to scale. Although the Ethereum blockchain is the most widely used blockchain and arguably the most secure, that doesn’t mean it doesn’t come with some shortcomings. The Ethereum Mainnet is known to have slow transaction times and expensive gas fees.

The scalability of blockchains is a mission-critical aspect of their adoption. With Layer 2 solutions, the exponential growth of users who use DeFi to access, store, and exchange value will not be stunted. While the blockchain trilemma is an ongoing challenge, it is expected to be overcome in the near future.

  • Best Ethereum layer 2 solutions is the support for sidechain aggregation of transactions, also referred to as the rollup technology.
  • However, one of the main problems with many blockchain networks is their scalability.
  • QuickSwap, a Uniswap-like decentralized exchange on Polygon, launched into the network’s deep liquidity stores to provide users a cheap alternative to Ethereum DEXes.
  • This could be for the purpose of launching a token or dapp while still taking advantage of the low cost and faster speeds enabled by not deploying smart contracts directly on the L1.

By settling ethereum layer 2 scaling solutions off-chain as layer 2 solution, fees are greatly reduced, allowing for instant micropayments. The Bitcoin lightning network also claims that it is capable of processing millions to billions of TPS, which is many times higher than legacy payment providers like Visa.
